Older homes and buildings may contain asbestos. In many cases, it's more dangerous to remove the asbestos than it is to leave it intact. Breaking up asbestos may cause fibers to become airborne, where they can be inhaled. Consult experts trained to detect asbestos in your home. These experts may test the air in your home to determine whether the asbestos is a risk to your health. Don't attempt to remove asbestos from your home — hire a qualified expert. The Environmental Protection Agency offers advice on its Web site for dealing with asbestos in the home.

Follow all safety precautions in your workplace, such as wearing protective equipment. You may also be required to shower and change out of your work clothes before taking a lunch break or going home. Talk to your doctor about other precautions you can take to protect yourself from asbestos exposure.

No alternative medicine treatments have proved helpful in treating mesothelioma. But complementary and alternative mesothelioma treatments may help control signs and symptoms. Discuss options with your doctor.

Mesothelioma can cause pressure within your chest that can make you feel as though you're always short of breath. Breathlessness can be distressing. Your doctor may recommend using an oxygen mask or taking medications to make you more comfortable, but often these aren't enough. Combining your doctor's recommended treatments with complementary and alternative approaches may help you feel better.

Alternative treatments that have shown some promise in helping people cope with breathlessness include:

• Acupuncture. Acupuncture uses thin needles inserted at precise points into your skin.
• Breath training. A nurse or physical therapist can teach you breathing techniques to use when you feel breathless. Sometimes you may feel breathless and begin to panic. Implementing these techniques may help you feel more in control of your breathing.
• Relaxation exercises. Slowly tensing and relaxing different muscle groups may help you feel more at ease and breathe easier. Your doctor may refer you to a therapist who can teach you relaxation exercises so that you can do them on your own.
• Sitting near a fan. Directing a fan to your face may help ease the sensation of breathlessness.

Complications from spreading cancer

As pleural mesothelioma spreads in the chest, it puts pressure on the structures in that area. This can cause complications, such as:

* Difficulty breathing
* Chest pain
* Difficulty swallowing
* Swelling caused by pressure on the large vein that leads from your upper body to your heart (superior vena cava syndrome)
* Pain caused by pressure on the nerves and spinal cord
* Accumulation of fluid in the chest (pleural effusion), which can compress the lung nearby and make breathing difficult

Death

Mesothelioma that progresses can lead to death. People who die of mesothelioma usually die from related complications, such as lung failure, heart problems, stroke and other causes.

A diagnosis of mesothelioma can be devastating not only to you, but also to your family and friends. Take time to experience the sadness and despair and to grieve. And remember that you decide how you'll spend your time and with whom you'll spend it.

In order to regain a sense of control, try to:

■Learn everything you can about mesothelioma. Write down a list of questions to ask your doctor. Ask your health care team for information to help you better understand your disease. Consult the National Cancer Institute (NCI) and the American Cancer Society (ACS). Both organizations have Web sites and toll-free telephone information lines. Call the NCI at 800-4-CANCER (800-422-6237). Call the ACS at 800-ACS-2345 (800-227-2345).
■Surround yourself with a support network. Close friends or family can help you with everyday tasks, such as getting you to appointments or treatment. If you have trouble asking for help, learn to be honest with yourself and accept help when you need it.
■Seek out other people with cancer. Ask your health care team about cancer support groups in your community. Sometimes there are questions that can only be answered by other people with cancer. Support groups offer a chance to ask these questions and receive support from people who understand your situation. Online support message boards, such as the ACS's Cancer Survivors Network, can offer similar benefits while allowing you to remain anonymous.
■Plan for the unknown. Ask your health care team about advance directives that give your family guidance on your medical wishes in case you can no longer speak for yourself. Talk to a lawyer about your will, if you haven't already done so.

If you have signs and symptoms that might indicate mesothelioma, your doctor will conduct a physical exam to check for any lumps or other unusual signs. Your doctor may order imaging scans, such as a chest X-ray or a computerized tomography (CT) scan of your chest or abdomen, to look for abnormalities.

It's not uncommon for mesothelioma to be misdiagnosed initially because mesothelioma is rare, and its signs and symptoms aren't specific. Your doctor will likely rule out other more common conditions before considering mesothelioma.

Biopsy


Biopsy, a procedure to remove a small portion of tissue for laboratory examination, is the only way to determine whether you have mesothelioma. Depending on what area of your body is affected, your doctor selects the right biopsy procedure for you. Options include:

■Fine-needle aspiration. The doctor removes fluid or a piece of tissue with a small needle inserted into your chest or abdomen.
■Thoracoscopy. Thoracoscopy allows the surgeon to see inside your chest. In this procedure, the surgeon makes one or more small incisions between your ribs. A tube with a tiny video camera is then inserted into your chest cavity — a procedure sometimes called video-assisted thoracoscopic surgery (VATS). Special surgical tools allow your surgeon to cut away tissue for testing.
■Laparoscopy. Laparoscopy allows the surgeon to see inside your abdomen. Using one or more small incisions into your abdomen, the surgeon inserts a tiny camera and special surgical tools to obtain a small piece of tissue for examination.
■Thoracotomy. Thoracotomy is surgery to open your chest between the ribs to allow a surgeon to check for signs of disease. He or she removes a sample of tissue for testing.
■Laparotomy. Laparotomy is surgery to open your abdomen to allow a surgeon to check for signs of disease. He or she removes a sample of tissue for testing.
The tissue sample is analyzed under a microscope to see whether the abnormal tissue is mesothelioma and what types of cells are involved. The type of mesothelioma you have determines your treatment plan.

Staging


Once mesothelioma is diagnosed, your doctor orders other tests to determine the extent, or stage, of the cancer. Imaging tests that may help determine the stage of your cancer include:

■Chest X-ray
■CT scans of the chest and abdomen
■Magnetic resonance imaging (MRI)
■Positron emission tomography (PET)
Once the extent of pleural mesothelioma is determined, a stage is assigned. Formal stages aren't available for other types of mesothelioma because these types are rare and aren't well studied. The stages of pleural mesothelioma are:

■I. Stage I pleural mesothelioma is considered localized cancer, meaning it's limited to one portion of the lining of the chest.
■II. Stage II mesothelioma may have spread beyond the lining of the chest to the diaphragm or to a lung.
■III. Stage III mesothelioma may have spread to other structures within the chest and may involve nearby lymph nodes.
■IV. Stage IV mesothelioma is an advanced cancer that has spread to distant areas (metastasized). Mesothelioma most commonly spreads (metastasizes) to the brain, lymph nodes in the chest and areas of the lung that are away from the tumor.

You're likely to start by first seeing your family doctor or a general practitioner. However, in some cases when you call to set up an appointment, you may be referred immediately to a doctor who specializes in lung diseases (pulmonologist) or abdominal problems (gastroenterologist).

Because appointments can be brief, and because there's often a lot of ground to cover, it's a good idea to be well prepared for your appointment. Here's some information to help you get ready for your appointment, and what to expect from your doctor.

What you can do


■Be aware of any pre-appointment restrictions. At the time you make the appointment, be sure to ask if there's anything you need to do in advance, such as restrict your diet.
■Write down any symptoms you're experiencing, including any that may seem unrelated to the reason for which you scheduled the appointment.
■Write down key personal information, including any major stresses or recent life changes. If you're worried about mesothelioma, make a list of all your occupations, even those you had for only a few months.
■Make a list of all medications, as well as any vitamins or supplements, that you're taking.
■Take a family member or friend along, if possible. Sometimes it can be difficult to soak up all the information provided during an appointment. Someone who accompanies you may remember something that you missed or forgot.
■Write down questions to ask your doctor.
Your time with your doctor is limited, so preparing a list of questions will help you make the most of your time together. List your questions from most important to least important in case time runs out. For mesothelioma, some basic questions to ask your doctor include:

■What is likely causing my symptoms or condition?
■What are other possible causes for my symptoms or condition?
■What kinds of tests do I need?
■Is my condition likely temporary or chronic?
■What is the best course of action?
■What are the alternatives to the primary approach that you're suggesting?
■I have these other health conditions. How can I best manage them together?
■Are there any restrictions that I need to follow?
■Should I see a specialist? What will it cost, and will my insurance cover seeing a specialist?
■Is there a generic alternative to the medicine you're prescribing me?
■Are there any brochures or other printed material that I can take home with me? What Web sites do you recommend?
■What will determine whether I should plan for a follow-up visit?
In addition to the questions that you've prepared to ask your doctor, don't hesitate to ask questions during your appointment at any time that you don't understand something.

What to expect from your doctor


Your doctor is likely to ask you a number of questions. Being ready to answer them may allow more time to cover other points you want to address. Your doctor may ask:

■When did you first begin experiencing symptoms?
■Have your symptoms been continuous, or occasional?
■How severe are your symptoms?
■What, if anything, seems to improve your symptoms?
■What, if anything, appears to worsen your symptoms?
■Do your symptoms affect your ability to work?

What you can do in the meantime


Try to avoid anything that worsens your signs and symptoms. For instance, if you're experiencing shortness of breath, try to take it easy until you can meet with your doctor.

Asbestos exposure: The primary risk factor for mesothelioma


Asbestos is a mineral that's found naturally in the environment. Asbestos fibers are strong and resistant to heat, making them useful in a wide variety of applications, such as in insulation, cement, brakes, shingles, flooring and many other products. People who work around asbestos fibers are thought to have the greatest risk of mesothelioma.

When asbestos is broken up, such as during the mining process or when removing asbestos insulation, dust may be created. If the dust is inhaled or swallowed, the asbestos fibers may settle in the lungs or in the stomach, where they can cause irritation that may lead to mesothelioma, though how exactly this happens isn't understood.

Mesothelioma risk is believed to be increased in people who are exposed to high levels of asbestos, in people who are exposed to asbestos over a long period of time and in people exposed to asbestos at a young age. It can take 30 to 40 years or more for mesothelioma to develop as a result of asbestos exposure.

Some people with years of asbestos exposure never develop mesothelioma. And yet, others with very brief exposure develop the disease. This indicates that other factors may be involved in determining whether someone gets mesothelioma or doesn't. For instance, you could inherit a predisposition to cancer or some other condition could increase your risk.


Possible risk factors


Factors that may increase the risk of mesothelioma include:

■Personal history of asbestos exposure. If you've been directly exposed to asbestos fibers at work or at home, your risk of mesothelioma is greatly increased.
■Living with someone who works with asbestos. People who are exposed to asbestos may carry the fibers home on their skin and clothing. These stray fibers can put others in the home at risk of mesothelioma. People who work with asbestos should shower and change clothes before leaving work.
■Smoking. Risk of mesothelioma is increased greatly in smokers who are exposed to asbestos.
■SV40. Some research indicates a link between mesothelioma and simian virus 40 (SV40), a virus originally found in monkeys. Millions of people may have been exposed to SV40 when receiving polio vaccinations between 1955 and 1963, because the vaccine was developed using monkey cells. Once it was discovered that SV40 was linked to certain cancers, the virus was removed from the polio vaccine. Whether SV40 increases the risk of mesothelioma is a point of debate, and more research is needed.
■Radiation. Some research links mesothelioma to the radioactive substance thorium dioxide, which was used along with X-rays to diagnose various health conditions from the 1920s to the 1950s. Thorium dioxide was later found to cause cancer and is no longer used.
■Family history. A family history of mesothelioma may increase your risk of mesothelioma, but more research is needed to understand this theory.


Complications


Complications from spreading cancer
As pleural mesothelioma spreads in the chest, it puts pressure on the structures in that area. This can cause complications, such as:

■Difficulty breathing
■Chest pain
■Difficulty swallowing
■Swelling caused by pressure on the large vein that leads from your upper body to your heart (superior vena cava syndrome)
■Pain caused by pressure on the nerves and spinal cord
■Accumulation of fluid in the chest (pleural effusion), which can compress the lung nearby and make breathing difficult

The volume of paperwork involved in managing insurance claim forms, co-pays, benefits statements, etc., can be overwhelming for a mesothelioma patient who is trying to concentrate on their health care, but by keeping organized, accurate records, you can eliminate unnecessary stress.

Perhaps the simplest way of keeping information to be referred to when filing an insurance claim, is to use a paper calendar to make note of all doctor's appointments, lab tests, procedures and treatments, as well as prescription drugs purchased. If this information is recorded on the day it occurs, you will have a complete chronological record when you need it. Other records you should organize in an expandable folder or binder include:

•Bills from all health care providers.
•Bills or receipts for prescription drugs.
•Receipts from co-pays or other health care related costs.
•Insurance claims filed.
•Reimbursements received.
Keeping medical expenses entered on a basic computer spreadsheet is another option, or, there is specialized software available for those who prefer a better display of information and the ability to search for and sort information. One of these programs is the "Medical Expense Manager" offered by Quicken. This program will allow you to track and organize medical expenses, tax deductions, medical and prescription history for multiple individuals, insurance payments and deductibles and billing or claims disputes.

Another alternative is to hire someone to manage your claims for you, and if you feel you need professional help, there are health insurance claims assistance services available in many areas. These professionals can file and track claims, contact health care providers and insurance companies to resolve claim issues, review medical bills for accuracy and appeal rejected claims. Fees for services rendered can vary significantly according to provider.

For those with Medicare coverage, a health insurance assistance program is available in every state. Counselors can help Medicare recipients understand their benefits, and can make suggestions on establishing a record keeping system.

Before you were diagnosed with mesothelioma, you may have been taking a small number of medications, or perhaps, none at all. Now, it is possible you have been prescribed several different drugs, and you may be taking over-the-counter medications as well. With the added stress of disease or treatment-related symptoms, it can be easy to confuse medications or simply to inadvertently miss taking a dose. Following are some easy ways to help organize and manage your medications:

•Compile a complete list of all drugs you are taking, including both their brand and generic names (i.e., Tylenol = acetaminophen), the dosage amount, times they are to be taken and any additional instructions (i.e., take with food, take before bedtime, etc.). This list should include both prescription and over-the-counter drugs, as well as any herbal supplements or vitamins you may be taking.
•When a new medication is prescribed, find out the name of the drug, how and when it should be taken, whether there can be any interactions with other medications, foods or beverages, what side effects are possible and what to do if you miss a dose. Write down this information and include it on your list.
•If possible, purchase all medications from the same pharmacy so that the records of what you purchased will be all in one place. Keep the patient information that is attached to prescriptions in case you need to refer to it later.
•If you need help organizing dosage schedules or have questions about medications you are taking, talk to your doctor, physician's assistant, nurse or pharmacist.
•Read and keep package inserts that come with your prescription medicine. This is not highly technical material or useless boilerplate wording. It is directly relevant to your experience with the medicine. More on package inserts.
•Read the label on the drug container before you taking any medication. If you are confused or can't read the label, have someone else read it to be sure you are taking the right medication.
•Do not skip scheduled doses. If you are taking medications for pain, they need to be taken as directed to be effective. If you have breakthrough pain between doses, follow your doctor's recommendations.
•If you don't feel confident that you will remember to take your medication on schedule, set an alarm on your clock, watch, cell phone or computer.
•Store medications in a safe place away from heat, light and humidity.
There are pill cases with compartments, organized by time of day, that may be helpful, and dose tracker devices such as 'Dose Dial' that will attach to any container, and can monitor the number of doses and/or the interval of doses.

Medications can play a significant role in how well you feel and can enhance, or in some cases, lessen your quality of life. Always follow directions when taking any medication, and if you have questions, concerns or are experiencing undesirable side effects you feel may be related to the drugs, speak frankly with a member of your health care team.

When you or a family member is going through the diagnostic process, or are being treated for mesothelioma, it is an undeniable fact that there will be a multitude of paperwork and reports involved. Although each individual medical professional or facility will keep its own record of your care, it is also important that you maintain an accurate, up to date medical history of your own.

It is likely that several different doctors, possibly at various locations, will be involved in your care, and each will generate a series of test results, treatment reports, scripts for medications, etc. By consolidating and organizing this information in one file, you will always have access to what you need if questions arise, or if a report is lost or inadvertently destroyed. It will also give you an opportunity to go over your records in your own time, and make note of any questions or concerns you might have. In this way, you will become a more active participant in your health care, and will feel more knowledgeable and in control of your situation. Keeping a personal medical file is also helpful in managing your health insurance claims, taxes and other legal matters.

Your personal medical record file should include the following:

•Information on past medical history, including the dates and details of any previously diagnosed illnesses such as diabetes or heart disease.
•Information on past physical examinations and screening tests.
•Immunization records.
•Contact information for all doctors, clinics and/or hospitals involved in your diagnosis, treatment or other care.
•Dates of initial diagnosis and a schedule for subsequent treatments.
•Copies of reports and diagnostic tests, including laboratory results, pathology reports and imaging tests (x-ray, CT, MRI, PET).
•Treatment information including surgical reports, names and dosages of drugs used for chemotherapy and sites and dosages for radiation therapy.
•Notes on treatment results including any complications or side effects experienced.
•Information on supportive care such as pain management or nutritional support. All medications you are taking, including prescription and over the counter drugs, should be listed by name, dosage and how often they are taken.
If you have been diagnosed with mesothelioma, it is best to collect information for your file each time you have an appointment, test or procedure. At each doctor appointment, ask for any records being added to your file, and if you have a laboratory test or a procedure of any kind, request a copy of the test results or the procedure report. If you are hospitalized for any reason, request a complete copy of your hospitalization records when you are released. Keep copies of medical bills and insurance claims.

How you organize your file is a matter of personal preference. Some people prefer a filing cabinet, while others prefer a folder, binder or box; some prefer to scan documents into a computer file. Records can be divided according to date or by category such as appointments, tests or treatments. However you choose to compile your file, be sure it is stored in a safe place. You may wish to leave an additional copy with a relative or friend in case of emergency.

The Health Insurance Portability and Accountability Act of 2003 assures that all patients have access to their medical records, so if you did not start a medical file when you were first diagnosed or treated, you can still obtain the information you need. In this case, it may be necessary to request your records in writing, and you may need to complete an "Authorization to Release Medical Information". Unfortunately, requesting records after the fact can take time, and you may be charged copying fees.

NEW! The Mesothelioma Center at the New York-Presbyterian Hospital and Columbia University is recruiting patients for a new clinical trial on treatment of mesothelioma with targeted radiation an chemotherapy. This multimodality treatment is an innovative approach led by oncologist Dr. Robert Taub. Click here to learn more.



CLINICAL TRIAL BASICS


Clinical trials are studies of the safety and/or effectiveness of new drugs being tested on humans. For mesothelioma, trials are being conducted to find a better and more effective means of treatment. Anyone interested in participating in a clinical trial should discuss the particular trial thoroughly with their doctor before a making a decision on whether it is right for them.

All clinical trials carry potential benefits and risks, and it is important that you have a complete understanding of what you might expect. For instance, since clinical trials are often conducted at larger cancer centers, in many cases, travel may be necessary to receive treatment and routine tests. On the other hand, care is provided at top-notch facilities by physicians who are leaders in the field of cancer research. Another benefit would be having access to the new drug before it is widely available, however, the new drug may ultimately be proven not as effective as the “standard” of care.

Eligibility requirements for clinical trials are not the same; each study has specific guidelines to participate. Some trials allow participation after other treatments have failed, while others require that the patient have no prior treatment. Your doctor should be able to advise you which trial might be the best fit in your particular case.

Some treatment trials are “randomized”, meaning the new treatment is compared with a current standard of treatment. Depending on which arm of the protocol you are assigned, you may receive the new treatment or the standard. You should be informed in advance of this eventuality by the doctor conducting the trial. Placebos (pills that contain no active ingredient) are rarely used in cancer trials.

For more information on the terminology associated with clinical trials, visit our clinical trial glossary.

TRIAL PHASES


Though mesothelioma has no cure, there are clinical trials currently underway to test new drugs and procedures in the fight against the disease. All clinical trials or studies are divided into different phases:

Phase I trials usually enroll only a small number of people and test how new drugs or procedures should be administered. Click here for an in-depth description of Phase I trials.

Phase II trials give early information about whether or not a new drug or procedure works and also provide information about safety and benefit. Click here for an in-depth description of Phase II trials.

Phase III trials compare promising new drugs or procedures with the current standard treatment. Large numbers of people from across the nation usually participate in Phase III trials and receive either the new treatment or the standard treatment. Click here for an in-depth description of Phase III trials.

ELIGIBILITY


In order to be sure the study results are accurate, trial participants in all phases must fit a certain profile. Eligibility for mesothelioma trials are often specific as to age, how long it has been since therapy, stage of disease, and other characteristics. To find out about the eligibility requirements and other information for the trials listed below, click on the clinical trial web site listed after each trial or call one of our MW Coordinators toll-free at 1-877-367-6376.

CLINICAL TRIALS AND MEDICARE


If you choose to enter a clinical trial and are on Medicare, it is important that you have a complete understanding of the trial itself, and what costs will or will not be covered under your Medicare policy.

Clinical trials for cancer are currently covered if:

•The trial is funded by the National Cancer Institute (NCI), the NCI-Designated Cancer Centers, the NCI-Sponsored Clinical Trials Cooperative Groups or other Federal agencies that fund cancer research.
•The goal of the trial is to diagnose or treat cancer (cancer prevention trials are not covered).
More on clinical trials and medicare.




CURRENT CLINICAL TRIALS


The National Cancer Institute states that the purpose of most listed clinical trials is to test new cancer treatments or new methods of diagnosing, screening for or preventing cancer. Because all potentially harmful side effects are not known before a trial is conducted, dose and schedule modifications may be required for participants if they develop side effects from the treatment or test. The therapy or test described in each clinical trial is intended for use by clinical oncologists in carefully structured settings, and may not prove to be more effective than standard treatment. A responsible investigator associated with this clinical trial should be consulted before using this protocol.

At present, the following trials are actively testing new drugs or treatments for mesothelioma. They are listed by title with a short description and have no particular order or endorsement.

Your role as the most important member of the team is to be a good consumer by gathering information and asking questions. Following are some easy ways to make the most of your appointment times with other members of your medical team:

•Once you know the day and time of your appointment, start a list of questions you want to ask that particular team member. These questions could be about mesothelioma itself, about test results or about treatments you are undergoing or considering. It is also a good idea to write down any symptoms you may be experiencing so that they can be addressed at this time. If there is something you don’t completely understand, ask to have it explained in simpler terms. Above all, don’t be embarrassed to ask questions or request clarifications.
•If possible, take along another person who can take notes, ask additional questions or record your appointment for later review. Sometimes it can be helpful to return home and play back what was discussed.
•Ask for written material or brochures that can help in making treatment or care decisions . These might include information on nutrition, pain management, support groups or hospice or home care.
Other than your doctors, who could include your primary care doctor, surgeons, medical oncologists, and/or radiation oncologists, you will probably have the most contact with your nursing staff and your social worker. These medical professionals can be your best source of practical assistance when trying to navigate the waters of a mesothelioma diagnosis.


Nurses


All specialized cancer treatment facilities have nurses who are familiar with implementing the cancer treatment plan initialized by your doctor, and are trained to administer medication, monitor side effects and conduct routine tests. Whether you are a hospital inpatient or outpatient, you can benefit greatly from developing a strong working relationship with your nursing staff.

You may also request home visits by a registered nurse, if necessary. If approved by your doctor, these visits may be covered under insurance. Be sure to check with your individual insurance provider for details.

Social Workers


Social workers are a good starting point for newly diagnosed patients who are overwhelmed by their diagnosis and the many things that have to be accomplished and decided.

Some types of social workers include:

•Oncology social workers specialize in assisting those diagnosed with cancer. Most cancer treatment facilities have certified oncology social workers on staff.
•Clinical social workers specialize in providing services aimed at family therapy and counseling, or counseling for those coping with a serious illness.
•Hospital social workers can help find resources in your local area such as home care, transportation services or support groups, and can also help you understand your diagnosis, your treatments and other care options.
Psychiatrists and Psychologists
Because of the emotional issues surrounding a mesothelioma diagnosis, some patients or their family members may benefit from the help of someone trained to deal with depression, anxiety or inability to cope. Don’t be afraid to ask for this type of help for yourself or your loved one – good emotional health is essential to quality of life.

•Psychiatrists are medical doctors who specialize in providing psychotherapy and other general psychological services to their patients. They are licensed to prescribe medications such as antidepressants and sleep aids. (Related: concerns about drug addition during cancer treatment.)
•Psychologists can provide many of the same services as a psychiatrist such as counseling for depression, anxiety, etc., however, they are not medical doctors. Most have PhD’s in psychology and counseling.


Nutritionists and Dietitians


Nutrition is another area that can greatly affect quality of life. Many patients lose weight because of anxiety associated with the diagnostic process, subsequent treatments or the natural progression of mesothelioma. Working with a nutritionist or dietitian as soon after diagnosis as possible is one of the most important benefits you can obtain from your health care team. These professionals can help you be sure you receive enough calories, vitamins and protein to maintain a healthy weight, as well as tailoring a program for those with concurrent health problems such as diabetes or high cholesterol. They can also suggest ways to minimize the side effects of chemotherapy or other aggressive treatment.

Most local hospitals have registered dietitians on staff, or you can ask your doctor to recommend someone in your area. As with other health care needs, check to see whether these services are covered under your insurance. If they are not, there may be community-based services available in your area at no cost.

A diagnosis of mesothelioma brings with it one of the most difficult challenges you or your loved one will ever face. One of the most important things to remember, however, is that there are resources to help with every aspect of care, and that you or your loved one is at the center of the health care team that will provide help in many different forms. Remember also that in addition to your doctor you can also get a second opinion from another physician.

The following physicians are specialists in the treatment of malignant mesothelioma. You will find links to their web sites, when available and to some of their published articles.They are listed in no particular order with no particular endorsement.

Mesothelioma is typically treated by an interdisciplinary team of doctors rather than by a single physician. You may run into professionals called oncologists, thoracic surgeons, and pulmonologists. Glossary of members of a thoracic oncology care team. More on choosing your mesothelioma doctor.

Palliative care is a specialized form of care that alleviates pain and other symptoms. The goal of palliative medicine is not to prolong life or hasten death, but rather, to keep the patient as comfortable as possible, while offering support to the patient and their family. Palliative care contributes to the quality of life for patients with life-threatening illnesses, such as mesothelioma, at any phase of the disease.

For the patients who are undergoing life-prolonging therapies, palliative care includes symptom management and therapy aimed at restoring function. For the dying patient, it addresses the traditional roles of the hospice movement. During the course of a serious illness, patients and their families should realize that the goals of care can, and do, change, sometimes rapidly. An open line of communication is essential to optimize patient care.


Symptoms Managed through Palliative Care
Some of the common symptoms managed through palliative care include:

•Pain
•Shortness of breath
•Fatigue
•Dry Mouth
•Loss of appetite
•Gastrointestinal problems
•Skin problems
•Anxiety/Depression


Pain

Pain management is one of the most important aspects of palliative care. Because it is now considered a medical specialty, you may wish to consult a physician well versed in pain management if your physician seems unable or unwilling to provide adequate pain control.

Many people with cancer experience pain. Statistics show that 30 to 40 per cent of patients in active cancer therapy, and 70 to 90 percent of patients with advanced cancer report pain. In most cases, pain can be controlled through medications prescribed according to the World Health Organization's Analgesic Ladder, an approach using various levels of medication based on the severity of pain. This type of pain treatment, using drugs, is called pharmacological therapy. Medications may include innon-opioid pain relievers, opioid pain relievers, adjuvant medications (those whose primary purpose is not for pain, but for other conditions), and topical treatments such as a patch, gel, or cream. A study published the Annals of Oncology found a reluctance among cancer patients to take opioid medications due to a belief that such medications are offerred only at the end of life.

Non-pharmacological therapies, those that do not rely primarily on medication to achieve effect, include therapeutic exercise and cognitive behavioral techniques such as deep breathing, muscle relaxation, imagery, meditation, biofeedback therapy, and distraction. Complementary and/or alternative approaches include acupuncture and massage therapy. Integretive medicine refers to the combination of mainstream conventional treatment such as surgery, chemotherapy and radiation with complementary therapies proven to have sound scientific evidence as to their safety and effectiveness.

Shortness of Breath
Shortness of breath, or dyspnea, affects 20 to 80 percent of palliative care patients. Causes of this condition may include, lung disease, fluid in the lungs, infection, anemia, or emotional factors such as anxiety. While medications or oxygen may be used to treat shortness of breath, sometimes measures such as changing position, using relaxation techniques, or improving air circulation may help. More on anemia from chemotherapy treatment.

Fatigue
Cancer-related fatigue may be the result of the general progression of the disease, the effects of medication, or the after effects of treatments such as surgery, chemotherapy, or radiation therapy. The following symptoms are usually associated with fatigue:

•Diminished energy level disproportionate to activity
•Diminished activity associated with physical or intellectual performance
•Diminished motivation; lack of interest in activities
•Exhaustion, apathy, or lethargy
•Generalized tiredness
•Sleep abnormalities
•Irritability, impatience, or changes in mood


The treatment of fatigue is based on first identifying, and then managing, the underlying cause of the fatigue. Once that is accomplished, interventions such as medication, exercise, stress management, and nutrition are used. More on fatigue in mesothelioma patients.

Dry Mouth
Dry mouth, or xerostoma, is another symptom addressed in palliative care. Causes may be dehydration, depression or anxiety, or may be a side effect of medications such as pain relievers, antidepressants, diuretics, or tranquilizers. Chemotherapy treatments or radiotherapy may also be a cause.

Relief of dry mouth can often be achieved by:

•Drinking plenty of fluids
•Sucking on ice chips or Vitamin C tablets
•Chewing sugarless gum
•Maintaining good oral hygiene
•Providing humidified air


Loss of Appetite

Patients with life-threatening illnesses often lose their appetite, and subsequently, lose weight. If the condition becomes too severe, it is called cachexia. Doctors uniformly agree that nutrition plays a vital role in the patient's well being. Causes of weight loss include inadequate intake of nutrients because the patient can not or does not want to eat, poor absorption of the food that is eaten, and changes in the patient's metabolism.

Weight loss may be managed by:

•Eating smaller, more frequent meals
•Eating high calorie, high protein foods
•Receiving nutritional counseling


There are also medications which may help depending on the patient's desired goal. Some of these medications stimulate appetite, but do not usually increase weight, some stimulate appetite and cause slight weight gain, and still others help prevent nausea and vomiting.

Gastrointestinal Problems
Gastrointestinal problems may be associated with the disease process itself, or as a side effect of treatments or medications the patient is receiving. These may include nausea, vomiting, constipation, and diarrhea.

As mentioned above, there are medications which can help with nausea and vomiting. Your doctor or a nutritionist may also be able to provide eating hints and/or special diets tailored to fit the patient's individual needs. More on diarreah in mesothelioma patients.

Skin Problems


There are a variety of skin problems which may accompany cancer, including dryness, itching, rash, sores, and ulcers. It is important to treat these conditions as quickly as possible in order to reduce discomfort and the risk of infection.

•Dryness may be lessened by adding baby or mineral oil to warm bath water, and by applying moisturizers. It is also important to drink 8-10 glasses of water per day.
•Itching and rash may be lessened by adding baking soda to cool bath water, or by applying a cool, moist cloth to itchy areas. Avoid harsh laundry detergents, and change sheets and towels daily.
•Keep skin clean and dry and check skin daily for pressure sores or ulcers which may become infected.


Anxiety/Depression


Anxiety is a hallmark of a life-threatening illness. Feelings of fear, worry, or apprehension may lead to long-term generalized anxiety, or short, intense panic attacks. Causes may include difficulty in coming to terms with the illness, fear of isolation and separation, poorly controlled pain, or side effects of medication.

Treatments to control anxiety may include stress management techniques, counseling, support of family and friends, and control of pain or side effects from medication.

Depression, while less common, often affects family members as well as the patient themselves. Depression may be related to loss of the ability to function, changing family roles, limited social and financial support, pain, or other symptoms such as shortness of breath.

Control of the above symptoms is accomplished through antidepressant medication, support and counseling, pain management, and stress management.

New approaches to treat malignant mesothelioma are currently being tested. They often combine traditional treatments or include something entirely new. They include:

•Angiogenesis and Anti-angiogenesis Drugs
Although progress has been made in the early detection of cancer, and in improved treatment options once cancer is diagnosed, there are still many cancers, including mesothelioma, which can not be cured and remain difficult to treat effectively. In recent years, researchers have learned a great deal about how cancer cells differ from normal cells and, in an effort to find drugs without the potentially severe side effects of chemotherapy, have now discovered drugs which target the tumor itself while sparing the body’s normal cells. One such group are the anti-angiogenesis drugs.

Learn more about anti-angiogenesis agents in the treatment of mesothelioma.

•Immunotherapy, sometimes called biological therapy, uses the body's own immune system to protect itself against disease. Researchers have found that the immune system may be able to recognize the difference between healthy cells and cancer cells, and eliminate those that become cancerous. Immunotherapy is designed to repair, stimulate, or enhance the immune system's natural anticancer function.
Substances used in immunotherapy, called biological response modifiers (BRMs) alter the interaction between the body's immune defenses and cancer, thereby improving the body's ability to fight disease. Some BRMs, such as cytokines and antibodies, occur naturally in the body, however, it is now possible to make BRMs in the laboratory that can imitate or influence natural immune response agents. These BRMs may:

•Enhance the immune system to fight cancer cell growth.
•Eliminate, regulate, or suppress body responses that permit cancer growth.
•Make cancer cells more susceptible to destruction by the immune system.
•Alter cancer cell's growth patterns to behave like normal cells.
•Block or reverse the process that changes a normal cell into a cancer cell.
•Prevent a cancer cell from spreading to other sites.
Many BRMs are currently being used in cancer treatment, including interferons, interleukins, tumor necrosis factor, colony-stimulating factors, monoclonal antibodies, and cancer vaccines.

More on immunotherapy for mesothelioma.


•Photodynamic therapy (PDT) is a type of cancer treatment based on the premise that single-celled organisms, if first treated with certain photosensitive drugs, will die when exposed to light at a particular frequency. PDT destroys cancerous cells by using this fixed frequency light to activate photosensitizing drugs which have accumulated in body tissues.
In PDT, a photosensitizing drug is administered intravenously. Within a specific time frame (usually a matter of days), the drug selectively concentrates in diseased cells, while rapidly being eliminated from normal cells. The treated cancer cells are then exposed to a laser light chosen for its ability to activate the photosensitizing agent. This laser light is delivered to the cancer site, (in the case of mesothelioma, the pleura), through a fiberoptic device that allows the laser light to be manipulated by the physician. As the agent in the treated cells absorbs the light, an active form of oxygen destroys the surrounding cancer cells. The light exposure must be carefully timed, so that it occurs when most of the photosensitizing drug has left the healthy cells, but is still present in cancerous ones.

The major side effect of PDT is skin sensitivity. Patients undergoing this type of therapy are usually advised to avoid direct and even indirect sunlight for at least six weeks. Other side effects may include nausea, vomiting, a metallic taste in the mouth, and eye sensitivity to light. These symptoms may sometimes come as a result of the injection of the photosensitizing agent.

•Gene therapy is an approach to treating potentially fatal or disabling diseases by modifying the expression of an individual's genes toward a therapeutic goal. The premise of gene therapy is based on correcting disease at the DNA level and compensating for the abnormal genes.
Replacement gene therapy replaces a mutated or missing gene, most often a tumor suppressor gene, with a normal copy of that gene which serves to keep cell growth and division under control. The p53 gene, the most common gene mutated in cancer has become a prime target for gene replacement, and has met with some success in inhibiting cell growth, inhibiting angiogenesis (the development of a tumor's blood supply), and inducing apoptosis (cell death).

Knockout gene therapy targets the products of oncogenes (a gene that can induce tumor formation) in an effort to render them inactive and reduce cell growth.

With constantly expanding knowledge of the genes associated with cancer, their functions, and the delivery systems used in administering these genes, gene therapy has a promising future.

•Complementary and alternative medicine covers a wide range of healing philosophies that conventional medicine does not commonly accept or make available to its patients. Some of these practices include the use of acupuncture, herbs, homeopathy, therapeutic massage, and Far Eastern medicine to treat health conditions.
These therapies may be used alone as an alternative to conventional medicine, or in addition to conventional medicine, in which case they are referred to as complementary. Many are considered holistic, meaning their focus is to treat the whole patient - physically, mentally, emotionally, and spiritually. These treatments are not widely taught as a part of the medical curriculum, are not generally used in hospitals, and, for the most part, are not covered under insurance policies.

Many cancer patients try various complementary and/or alternative medicine techniques during the course of their treatment, and although they may not work for everyone, some patients benefit by managing their symptoms or side effects. One important caveat, is to discuss any complementary or alternative treatments you may be considering with your doctor to be sure nothing interferes with your conventional care. For instance, dietary supplements such as herbs or vitamins may be "natural", but not necessarily "safe". They may lessen the effectiveness of certain anticancer drugs, or when taken with other drugs or in large doses, may actually cause harm. Since supplements of this nature are not governed by the FDA (Food and Drug Administration), and a prescription is not necessary to purchase, it is up to the consumer to make informed and conscientious decisions regarding their use.

Your personal physician may be able to advise you about the use of complementary and alternative treatments and therapies, and how they relate to mesothelioma.

The combinaton of complementary and conventional therapies is sometimes referred to as integrative medicine.

•Unconventional methods of cancer treatment make claims that can not be scientifically substantiated. They commonly claim to be effective against cancers that are considered incurable, and tout treatments with relatively few, if any, side effects.
The use of these unconventional methods may result in the loss of valuable time and the opportunity to receive potentially effective therapy. It is always important to remain in the care of a qualified physician who uses accepted methods of treatment or who is participating in scientifically designed investigational therapies.

Radiation therapy, also called radiotherapy, treats cancer by using penetrating beams of high energy or streams of particles called radiation. In treating mesothelioma, radiation may be used aggressively in combination with surgery, or palliatively to control symptoms.

In an aggressive combined modality approach, radiation is used to attack microscopic or residual disease remaining in the chest cavity after extrapleural pnuemonectomy. An example of this is Intensity Modulated Radiation Therapy (IMRT), which uses x-rays of varying intensities in conjunction with computer generated images to deliver targeted radiation directly to cancer cells while reducing the amount of radiation to surrounding healthy tissue. More on Intensity Modulated Radiation Therapy (IMRT).

Used palliatively, radiation can help control metastases (spread) of the tumor along tracks left by invasive procedures such as thoracoscopy, needle biopsy and chest tube drainage, or to control disease symptoms, such as pain or shortness of breath.

An exciting new development in radiation oncology is tomotherapy. A brief description of steps in the helical tomotherapy process

Diagnostic Procedures


As previously mentioned in the "Symptoms" section of this website, a diagnosis of mesothelioma from fluid is many times inconclusive. Given this fact, diagnostic surgery becomes a necessary next step in confirming and staging mesothelioma.

Thoracoscopy enables a physician to evaluate the pleural cavity and to conduct multiple tissue biopsies under direct vision. In up to 98% of cases, a definitive diagnosis can be obtained. Often, chemical pleurodesis aimed at relieving the accumulation of fluid in the intrapleural space, can be accomplished during the same procedure. It is also possible to gauge the extent of the tumor, and make a determination of surgical resectability. While less invasive than an open biopsy, it can only be performed on patients where tumor has not obliterated the pleural space.

VATS, or video-assisted thoracic surgery is an alternative to thoracoscopy, although because of its more invasive nature, concerns of tumor seeding increase. By utilizing small incisions, the physician can view the pleural space with the assistance of a camera, and obtain sufficient tissue samples for analysis by a pathologist. Extent of the tumor (i.e., pleural involvement, chest wall invasion) may also determined, and recommendation as to the type of debulking procedure necessary can be made at this time.

Mediastinoscopy is sometimes used as an aid in staging extent of disease when enlarged nodes are seen using imaging techniques.

Laproscopy is used in mesothelioma patients in cases where imaging techniques suggest possible invasion of the tumor through the diaphragm. This information can be important in evaluating a patient for potential pleurectomy or extrapleural pneumonectomy.

Palliative Procedures


Palliative surgical procedures are those which treat a symptom of mesothelioma, without aggressively treating the disease itself.

Chest Tube Drainage and Pleurodesis is considered the most common of palliative treatments. Fluid build-up, or pleural effusion, is most often the first symptom which will prompt mesothelioma patients to seek medical attention. Once this effusion has occurred, it is many times persistent, returning rapidly after initial thoracentesis (draining of the fluid). In order to eliminate this problem, the pleural space must be closed. This is accomplished by use of a talc slurry or other sclerosing agent which produces an adhesion.

Thoracoscopy and Pleurodesis is done in conjunction with VATS using a powdered form of talc versus talc slurry. Both this and chest tube drainage and pleurodesis will be only effective if there is no tumor encasing the lung which restricts its expansion.

Pleuroperitoneal Shunt plays a limited role in palliation for several reasons. It involves placement of a catheter run under the skin from the pleural to the peritoneal cavity. Obstruction of the catheter and possible seeding of the tumor into the abdominal cavity may be concerns.

Pleurectomy, used as a palliative procedure, may be performed where more extensive surgery is not an option. In these cases, it is understood that all visible or gross tumor will not be removed. It is considered the most effective means of controlling pleural effusion in cases where the lung's expansion is restricted by disease.

Potentially Curative Procedures


These procedures are performed with "curative intent". Their goal is removal of all gross disease, with the knowledge that microscopic disease will most likely remain. Adjuvant therapy (another form of treatment in addition to the primary therapy) is typically aimed at eliminating residual disease.

For Pleural Mesothelioma:

•Pleurectomy/Decortication is usually performed on patients with early stage disease (Stage I and selected Stage II), and attempts to remove all gross tumor. If it is found that all tumor can not be removed without removing the lung, this may be done at the same time and is called pneumonectomy.
•Extrapleural Pneumonectomy is considerably more radical than other surgical approaches, and should be carried out by surgeons with great expertise in evaluating patients and performing the procedure itself. (See Finding Specialists.) Because in the past surgery alone has failed to effect a cure, or even to help prolong life for any extended period of time, it is currently being combined with traditional chemotherapy and/or radiation, or other new approaches such as gene therapy, immunotherapy or photodynamic therapy.


General Patient Selection Criteria for Extrapleural Pneumonectomy

Extrapleural pneumonectomy is a serious operation, and doctors experienced in this procedure choose their patients carefully. It is up to each individual surgeon to advise the patient on its feasibility and to conduct whatever tests he/she feel are necessary to optimize the patient's chances for survival and recovery. Following is a general list of patient selection criteria. This list may not be all inclusive, and may vary according to the preference of the surgeon.

•Karnofsky Performance Status score of >70. This score relates to what symptoms of disease the patient may be experiencing and how well they are able to conduct their daily activities. Some surgeons may require a higher performance status than others.
•Adequate renal (kidney) and liver function tests; no significant kidney or liver disease.
•Normal cardiac function per electrocardiogram and echocardiography.
•Adequate pulmonary function to tolerate the surgery.
•Disease limited to the ipsilateral hemithorax (the same side of the chest in which the mesothelioma is located) with no penetration of the diaphragm, extension to the heart or extensive involvement of the chest wall.
•Age of the patient is taken into consideration, but may not be as important as their overall status.
Surgeries of this nature should always be done with a complete understanding of the possible benefits and risks involved. If you are considering surgery as a treatment option, speak openly with your doctor about your concerns, and be sure all of your questions are answered to your satisfaction.




For Peritoneal Mesothelioma:

•Cytoreductive Surgery is aimed at removing all or nearly all of the gross or visible tumor in the peritoneal cavity. In order to treat any remaining cancer cells, Intra-Peritoneal Hyperthermic (heated) Chemotherapy (IPHC) is then delivered to the abdominal cavity. The type of chemotherapy drug used may vary according to the physician’s preference. Click here for more on treatment of peritoneal mesothelioma.

The treatment program for mesothelioma depends on many factors, including: the stage of the cancer, where the cancer is, how far the cancer has spread, how the cancer cells look under the microscope and the patient’s age and desires.


TIME MATTERS

People diagnosed with this disease are often told the expected survival rate is only eight to twelve months. However, specialists in treating malignant mesothelioma at the leading cancer centers often have better statistics.

For instance, the five-year survival rate has approached 40% for selected patients of Dr. David Sugarbaker at Brigham and Women’s Center in Boston. To qualify for Dr. Sugarbaker’s treatment you must meet certain criteria. One of them is being in the early stages of the disease, so time is of the essence. To find out more about Dr. Sugarbaker and other physicians and cancer centers specializing in mesothelioma click on Finding Specialists.

Keeping track of your medical treatment is useful and a personal medical records file can help.



TRADITIONAL CARE


There are three traditional kinds of treatment for patients with malignant mesothelioma:

•Surgery (taking out the cancer)
•Chemotherapy (using drugs to fight the cancer)
•Radiation Therapy (using high-dose x-rays or other high-energy rays to kill cancer cells)
Often two or more of these are combined in the course of treatment. (NEW! Click here for the newest trial of trimodal lung-sparing treatment for pleural mesothelioma: The Columbia Protocol.)



MESOMARK BLOOD TEST

In January 2007, the Food and Drug Administration (FDA) approved the MESOMARK assay to help monitor response to treatment in epithelial and bi-phasic malignant mesothelioma patients. A specific protein, or biomarker, called Soluble Mesothelin-Related Peptide (SMRP), may be released into the blood by mesothelioma cancer cells. By measuring the amount of SMRP in a blood sample, doctors may be able to better monitor a patient's progress. Based on the limited amount of data currently available, use of this test may be beneficial, but effectiveness has not been determined at this time. The MESOMARK blood test has NOT yet been approved for the early diagnosis of mesothelioma.

This test has been approved as a Humanitarian Use Device (HUD), meaning that physicians must follow certain procedures to qualify their patients for testing. Once the physician is certified, informational brochures will be sent to be distributed to each applicable patient.

Those wishing to take part in

MESOMARK testing will be asked to provide one or more samples of blood. The blood samples will then be sent to a national reference laboratory for testing. In conjunction with other clinical and laboratory data obtained by your doctor, decisions regarding your treatment and care may be simplified. You may discontinue testing at any time.

The costs associated with the MESOMARK blood test may not be covered under health insurance, therefore, you may be required to pay all or part of the costs out of pocket. It is recommended that you check with your insurance carrier to determine whether coverage is available under your policy.

A diagnosis of any specific type of cancer often means ruling out other cancers in the process. This is true in the case of mesothelioma, where the most common “differential diagnosis” is that of adenocarcinoma versus mesothelioma.

During the biopsy procedure, the surgeon removes tissue samples to be sent to the laboratory. In the lab, slides are produced and then viewed and analyzed by a pathologist. These tissue specimens arrive at the lab with a request form that details patient information and history along with a description of the site in the body from which the specimen was obtained. Each individual specimen is numbered for each patient.

The pathologist then does a “gross examination” which consists of describing the tissue, and then placing it in a plastic cassette. The cassettes are then placed in a fixative that preserves the tissue permanently. Once the tissue has been fixed, it is processed into a paraffin block that will allow the pathologist to slice off thin microscopic sections that will then be stained to determine the patient’s diagnosis.

Immunohistochemistry is defined as “a method of analyzing and identifying cell types based on the binding of antibodies to specific components of the cell”. It is this process that helps diagnose mesothelioma versus adenocarcinoma (or other types of cancer).

Early on, the “markers” which helped distinguish mesothelioma from adenocarcinoma were “negative markers”; those expressed in adenocarcinomas, but not in mesotheliomas. This made it more difficult to confirm a diagnosis, because pathologists were dealing with the absence of, rather than the presence of certain markers. Some of these markers, which are normally “positive” in an adenocarcinoma diagnosis and “negative” in a mesothelioma diagnosis, are carcinoembryonic antigen (CEA), CD 15 (LeuM1), epithelial glycoprotein (Bg8), tumor glycoprotein (BerEp4) and tumor glycoprotein (MOC-31).

In more recent years, “positive markers” expressed by mesotheliomas have come to the forefront. Some of the markers which are normally “positive” in mesotheliomas and “negative” in adenocarcincomas are calretinin, cytokeratin 5, HBME-1, mesothelin, N-cadherin, thrombomodulin, vimentin and Wilm’s tumor gene product (WT-1).

It is important to remember that while the above markers are commonly used to help diagnose the epithelial sub-type of mesothelioma, that they may also be expressed in other types of cancer, and may not necessarily apply to the bi-phasic or sarcomatoid sub-types of mesothelioma. Your doctor can always contact a more specialized lab if he/she feels your diagnosis is in any way inconclusive.

Pathology, or the scientific study of cells, tissue, or fluid taken from the body is an integral part of a mesothelioma diagnosis. Most hospitals have their own pathology labs staffed by board-certified pathologists and licensed technologists. The importance of pathological diagnosis can not be underestimated, since the course of treatment is dependent upon an accurate diagnosis.

To make a diagnosis, pathologists examine tissue under a microscope, and based on established criteria, make a determination of benign vs. malignant cells. (More on biopsy tissue processing.) Subsequently, the type of cancer is determined. Although most pathologists have a general expertise of various diseases, a small number acquire training in a subspecialty, such as mesothelioma. These are physicians who have received world-wide recognition as premier experts, and have achieved high acclaim for their research, published articles and abstracts, and teaching. For a list of expert pathologists in the field of mesothelioma diagnosis, please call the MW toll free at 1-877-367-6376 or fill in the form at the bottom of this page specifying your request.

Knowing the stage is a factor in helping the doctor form a treatment plan. Mesothelioma is considered localized if the cancer is confined to the pleura, or advanced if it has spread beyond the pleura to other parts of the body such as the lungs, chest wall, abdominal cavity, or lymph nodes.

How is mesothelioma diagnosed?
A diagnosis of mesothelioma is most often obtained with careful assessment of clinical and radiological findings in addition to a confirming tissue biopsy. (Learn about typical mesothelioma symptoms.) A review of the patient's medical history, including history of asbestos exposure is taken, followed by a complete physical examination, x-rays of the chest or abdomen, and lung function tests. A CT scan or MRI may also be done at this time. If any of these preliminary tests prove suspicious for mesothelioma; a biopsy is necessary to confirm this diagnosis.

Imaging Techniques and Their Value in Diagnosing and Assessing Mesothelioma
There are several imaging techniques which may prove useful when mesothelioma is suspected due to the presence of pleural effusion combined with a history of occupational or secondary asbestos exposure. While these imaging techniques can be valuable in assessing the possibility of the cancer, definitive diagnosis is still most often established through fluid diagnosis or tissue biopsy.

Some of the most commonly used imaging methods include:

• X-ray

A chest x-ray can reveal pleural effusion (fluid build-up) which is confined to either the right (60%) or left (40%) lung. On occasion, a mass may be seen. Signs of prior non-cancerous asbestos disease, such as pleural plaques or pleural calcification, or scarring due to asbestosis may also be noted.

• Computed Tomography (CT)

CT scans are also able to define pleural effusion, as well as pleural thickening, pleural calcification, thickening of interlobular fissures, or possible chest wall invasion. CT, however, is not able to differentiate between changes associated with benign asbestos disease (pleural disease), or differentiate between adenocarcinoma of the lung wh

ich may have spread to the pleura verses mesothelioma. CT scans may also be valuable in guiding fine needle aspiration of pleural masses for tissue diagnosis.

• Magnetic Resonance Imaging (MRI)

MRI scans are most often used to determine the extent of tumor prior to aggressive treatment. Because they provide images in multiple planes, they are better able to identify tumors as opposed to normal structures. They are also more accurate than CT scans in assessing enlargement of the mediastinal lymph nodes (those lymph nodes which lie between the two lungs), as well as a clear diaphragmatic surface, both of which play an important role in surgical candidacy.

• Positron Emission Tomography (PET)

PET imaging is now becoming an important part of the diagnosis and evaluation of mesothelioma. While PET scans are more expensive than other types of imaging, and are not always covered under insurance, they are now considered to be the most diagnostic of tumor sites, as well as the most superior in determining the staging of mesothelioma. Further explanation of PET scans.

• CT/PET

For patients who may be candidates for aggressive multimodality treatment (surgery, chemotherapy and radiation), accurate clinical staging is extremely important. Integrated CT/PET imaging provides a relatively new tool in this respect, and has become the imaging technique of choice for determining surgical eligibility. By combining the benefits of CT and PET (anatomic and metabolic information) into a single scan, this technology can more accurately determine the stage of the cancer, and can help identify the best treatment option for the patient. Read about a study of CT-PET imaging in preoperative evaluation of patients with malignant pleural mesothelioma.

A needle biopsy of the mass, or the removal and examination of the fluid surrounding the lung, may be used for diagnosis, however, because these samples are sometimes inadequate as far as determining cell type (epithelial, sarcomatous, or mixed) or because of the unreliability of fluid diagnosis, open pleural biopsy may be recommended. In a pleural biopsy procedure, a surgeon will make a small incision through the chest wall and insert a thin, lighted tube called a thoracoscope into the chest between two ribs. He will then remove a sample of tissue to be reviewed under a microscope by a pathologist. In a peritoneal biopsy, the doctor makes a small incision in the abdomen and inserts a peritoneoscope into the abdominal cavity.

Once mesothelioma is suspected through imaging tests, it is confirmed by pathological examination. Tissue is removed, put under the microscope, and a pathologist makes a definitive diagnosis, and issues a pathology report. This is the end of a process that usually begins with symptoms that send most people to the doctor: a fluid build-up or pleural effusions, shortness of breath, pain in the chest, or pain or swelling in the abdomen. The doctor may order an x-ray or CT scan of the chest or abdomen. If further examination is warranted, the following tests may be done:

•Video-Assisted Thoracoscopic Surgery (VATS)

Over the past decade, the use of video-assisted thoracic surgery (VATS) has become one of the most widely used tools in the diagnosis of mesothelioma. Biopsies of the pleural lining, nodules, masses and pleural fluid can now easily be obtained using this minimally invasive procedure, and other therapies such as pleurodesis (talc) for pleural effusions can be done concurrently.While the patient is under general anesthesia, several small incisions or “ports” are made through the chest wall. The surgeon then inserts a small camera, via a scope, into one incision, and other surgical instruments used to retrieve tissue samples into the other incisions. By looking at a video screen showing the camera images, the surgeon is able to complete whatever procedures are necessary

In many cases, this video-assisted technique is able to replace thoracotomy, which requires a much larger incision to gain access to the chest cavity, and because it is minimally invasive, the patient most often has less post-operative pain and a potentially shorter recovery period.

•Thoracoscopy

For pleural mesothelioma the doctor may look inside the chest cavity with a special instrument called a thoracoscope. A cut will be made through the chest wall and the thoracoscope will be put into the chest between two ribs. This test is usually done in a hospital with a local anesthetic or painkiller.

If fluid has collected in your chest, your doctor may drain the fluid out of your body by putting a needle into your chest and use gentle suction to remove the fluid. This is called thoracentesis.

•Peritoneoscopy

For peritoneal mesothelioma the doctor may also look inside the abdomen with a special tool called a peritoneoscope. The peritoneoscope is put into an opening made in the abdomen. This test is usually done in the hospital under a local anesthetic.

If fluid has collected in your abdomen, your doctor may drain the fluid out of your body by putting a needle into your abdomen and using gentle suction to remove the fluid. This process is called paracentesis.

•Biopsy

If abnormal tissue is found, the doctor will need to cut out a small piece and have it looked at under a microscope. This is usually done during the thoracoscopy or peritoneoscopy, but can be done during surgery. More on needle biopsies.

The early symptoms of mesothelioma are generally non-specific, and may lead to a delay in diagnosis. Sometimes resembling viral pneumonia, pleural mesothelioma patients may present with shortness of breath, chest pain and/or persistent cough; some patients show no symptoms at all. A chest x-ray may show a build-up of fluid or pleural effusion (discussed below). The right lung is affected 60% of the time, with involvement of both lungs being seen in approximately 5% of patients at the time of diagnosis. Less common symptoms of pleural mesothelioma include fever, night sweats and weight loss. Symptoms of peritoneal mesothelioma may include pain or swelling in the abdomen due to a build-up of fluid, nausea, weight loss, bowel obstruction, anemia or swelling of the feet.

PLEASE KEEP IN MIND THAT THESE SYMPTOMS MAY BE CAUSED BY MESOTHELIOMA OR BY OTHER LESS SERIOUS CONDITIONS. ONLY A DOCTOR CAN MAKE A DEFINITIVE DIAGNOSIS.

Pleural Effusion


One of the most common symptoms of mesothelioma is a pleural effusion, or an accumulation of fluid between the parietal pleura (the pleura covering the chest wall and diaphragm) and the visceral pleura (the pleura covering the lungs). Both of these membranes are covered with mesothelial cells which, under normal conditions, produce a small amount of fluid that acts as a lubricant between the chest wall and the lung. Any excess fluid is absorbed by blood and lymph vessels maintaining a balance. When too much fluid forms, the result is an effusion.


Types

Pleural effusion is broken down into two categories, transudates and exudates. A transudate is a clear fluid that forms not because the pleural surfaces are diseased, but because of an imbalance between the normal production and removal of the fluid. The most common cause of transudative fluid is congestive heart failure. An exudate, which is often cloudy and contains many cells and proteins, results from disease of the pleura itself, and is common to mesothelioma. To determine whether a fluid is a transudate or exudate, a diagnostic thoracentesis, in which a needle or catheter is used to obtain a fluid sample, may be conducted.

Symptoms


As the volume of fluid increases, shortness of breath, known as "dyspnea", and sometimes pain, ranging from mild to stabbing, may occur. Some patients may experience a dry cough. When the doctor listens to the patient’s chest with a stethoscope, normal breath sounds are muted, and tapping on the chest will reveal dull rather than hollow sounds.

Diagnosis


Diagnosis of pleural effusion is usually accomplished with a simple chest x-ray, although CT scans or ultrasound may also be used. A special x-ray technique, called a lateral decubitus film, may be used to detect smaller effusions or to enable the physician to estimate of the amount of fluid present. If the underlying cause of the effusion is readily apparent (such as in the case of severe congestive heart failure), sampling of the fluid may not be necessary, however, because pleural effusion may be symptomatic of a number of disease processes from benign to malignant, a fluid sample is generally taken. Diagnostic thoracentesis, in which cells are extracted from the pleural cavity, is commonly done when the possibility of mesothelioma exists, however, in up to 85% of cases, the fluid tests negative or inconclusive even though cancer is present. It is ultimately a needle biopsy of the pleura (lining of the lung) or an open surgical biopsy which confirms a mesothelioma diagnosis.

Treatment


Pleural effusion caused by heart failure or infection can usually be resolved by directing treatment at the cause, however, when testing has realized no diagnosis, and fluid continues to build or recur, doctors may recommend chest tube drainage and chemical pleurodesis. Chemical pleurodesis is a technique in which a sclerosing agent is used to abrade the pleural surfaces producing an adhesion between the parietal and visceral pleurae. This will prevent further effusion by eliminating the pleural space. Talc appears to be the most effective agent for pleurodesis, with a success rate of nearly 95%. It is highly effective when administered by either poudrage or slurry. Poudrage is the most widely used method of instilling talc into the pleural space. Before spraying the talc, the medical team removes all pleural fluid to completely collapse the lung. After the talc is administered, they inspect the pleural cavity to be sure the talc has been evenly distributed over the pleural surface. Some doctors prefer to use talc mixed with saline solution which forms a wet slurry that can roll around the pleural cavity.
