Mesothelioma treatment options (traditional and new treatments being studied)
The oldest staging system and the one most often used is the Butchart system, which is based mainly on the extent of primary tumor mass and divides mesotheliomas into four stages.
What is the prognosis for mesothelioma
Like most cancers, the prognosis for this disease often depends on how early it is diagnosed and how aggressively it is treated. Unfortunately, mesothelioma is often found at a stage in which a cure is unobtainable. Many will succumb to the disease within one year of diagnosis.
How much asbestos exposure does it take to get mesothelioma
An exposure of as little as one or two months can result in mesothelioma 30 or 40 years later and in some cases, as much as 70 years later.
What causes mesothelioma
Most people with malignant mesothelioma have worked on jobs where they breathed asbestos. Usually, this involves men over 40 years of age. Others have been exposed to asbestos in a household environment, often without knowing it. Interestingly, the number of new cases of mesothelioma has been relatively stable since 1983, the same time that the restrictions on asbestos were instituted by the U.S. Occupational Safety and Health Administration (OSHA). In Europe, the number of new cases of mesothelioma continues to rise.
What are the symptoms of mesothelioma
Most people present with complaints of shortness of breath. They also can have complaints of chest pain. Surprisingly, this pain is often not pleuritic; that is, it does not get worse with deep breathing. This is surprising in that the pleura (outer surface of the lung) is often involved in this disease, and most other diseases involving the pleura are often associated with pleuritic pain (pain that worsens with deep breathing). Patients may also be asymptomatic, with the disease discovered by physical exam or an abnormal chest X-ray.
As the disease progresses, shortness of breath increases, and weight loss, decreased appetite, and night sweats can develop. Local invasion by the tumor can result in changing of voice, loss of function of the diaphragm, and symptoms specific to the area and involvement of adjacent structures.
What is mesothelioma
Mesothelioma is a rare form of cancer (malignancy) that most frequently arises from the cells lining the sacs of the chest (the pleura) or the abdomen (the peritoneum). Pleural mesothelioma is the most common form, often presenting with symptoms in the chest area. Peritoneal mesothelioma is much less common. This can effect the organs in the abdomen, and its symptoms are related to this area of the body, that is, abdominal swelling, nausea, vomiting, and bowel obstruction. The rarest form of mesothelioma is pericardial mesothelioma, which involves the sac surrounding the heart.
There are two major cell types of mesothelioma, epithelial and sarcomatoid. Sometimes both of these cell types can be present. The sarcomatoid type is rarer and occurs in only about 15% of cases; it portends a poorer prognosis. In very rare cases, mesothelioma can originate from benign, non-malignant cells. This so-called benign mesothelioma can be cured surgically.
Mesothelioma facts
Mesothelioma is a cancer that arises from the cells lining the chest or abdominal cavities.
Mesothelioma typically results from exposure to asbestos.
When mesothelioma affects the chest, the doctor may look inside the chest cavity with a special instrument called a thoracoscope.
When mesothelioma affects the abdomen, the doctor may look inside the abdomen with a special tool called a peritoneoscope.
Mesothelioma is diagnosed by a biopsy.
The outlook for patients with mesothelioma depends on how early the disease is detected and how aggressively it is treated.
Mesothelioma Diagnosed
Mesothelioma is a rare type of cancer that occurs in the lining of the body's internal organs, a thin layer of cells known as the mesothelium, which gives mesothelioma its name. While very thin, this layer of cells is vitally important to organ function and the health of the inner body structures. There are three recognized types of mesothelioma. Pleural mesothelioma occurs in the pleural lining of the lungs and is the most common form of the disease. Peritoneal mesothelioma occurs within the peritoneum, which lines the abdominal cavity and is the second most common form of the disease. Pericardial mesothelioma is the rarest variety of the disease and occurs in the pericardial lining of the heart. The primary cause of mesothelioma is exposure to asbestos, though other factors, such as smoking may increase the likeliness of mesothelioma in certain individuals.
How is Mesothelioma Treated?
Mesothelioma is an aggressive cancer but can be managed with chemotherapy, radiation therapy, and surgery. Currently, there is no known cure for asbestos cancer but several mesothelioma treatment regimens have proven to be successful in helping the mesothelioma patient avoid pain and discomfort caused by the disease. Several therapies have emerged in recent years that have extended survival rates of mesothelioma patients to levels previously thought to be impossible. Cancer centers have initiated hundreds of clinical trials in recent years to help mesothelioma patients find a therapy that works for them while still working towards a cure for future mesothelioma patients. Progressive therapies are now being developed through the International Mesothelioma Program under the direction of thoracic specialist Dr. David Sugarbaker.
How is Mesothelioma Diagnosed?
Malignant mesothelioma can be difficult to diagnose because symptoms of the disease often closely mimic those of less serious conditions. Mesothelioma diagnosis often require X-ray and other body scans (CT or MRI) in addition to a biopsy to conclusively diagnose mesothelioma. Nevertheless, those experiencing chronic cough, difficulty swallowing, chest pain, or breathing difficulties should alert their physician immediately. This is particularly true among those with a known asbestos-exposure history. Those with asbestos exposure history should communicate this to their physician even before mesothelioma symptoms appear so that they may be able to alert patients to warning signs of the disease. If detected early enough, patients may be eligible for aggressive mesothelioma treatment options, including surgical resection of the mesothelioma cancer and affected tissue. Oncologists and thoracic specialists will be able to assist the patient in determining the extent of the disease and the best mesothelioma treatment options for that particular patient.
Asbestos Exposure
Asbestos exposure was common among industrial workers. Among the more common jobsites were those in the shipbuilding industry, such as the Todd Shipyards or Newport News Naval Shipyard. Other jobsites include power plants, chemical manufacturing, or the metal works industry. Those with asbestos history should notify their doctor and learn of possible warning signs of mesothelioma caused by exposure.

Mesothelioma Resource Online has created and developed this site to provide answers and support for people diagnosed with mesothelioma cancer, as well as their families and loved ones. Mesothelioma is a rare form of cancer that is caused by exposure to asbestos and has long been considered a mystery and incurable. However, over the past two decades, physicians, scientists and researchers have begun to unravel this mystery and help people diagnose mesothelioma in its earlier stages, while providing more extensive forms of treatment, vast resources, and general information to make coping and survival more about optimism rather than uncertainty. Mesothelioma Resource Online is presented by Seeger Weiss LLP.

Mesothelioma Cancer
Previously, diagnosing mesothelioma in its early stages had been a difficult, almost impossible task, because the early symptoms of this disease resemble those of similar diseases and sometimes even basic illnesses. The severity of mesothelioma is defined by four stages, with prognosis becoming bleaker as each stage progresses, so the discovery of symptoms in the first two stages is essential for ensuring a greater mesothelioma life expectancy. Additionally, the difficulty in diagnosing mesothelioma cancer is caused by a long latency period, meaning that it can take decades between the initial exposure to asbestos and development of symptoms. However, if you or a loved one has been exposed to asbestos and experiences initial symptoms such as chest pain, violent coughing, and fatigue, it is essential that you consult with a physician immediately.
Veterans and Mesothelioma
During the better part of the 20th century, the United States Armed Forces used asbestos in the production of many types of ships, buildings and vehicles, thus exposing countless soldiers and workers to this terrible mineral. At its peak, asbestos was used predominantly in factories during World War II and many U.S. veterans suffered from mesothelioma as a result, because the harmful effects of asbestos were not known until decades later. Even now, as asbestos use and production has declined significantly, many veterans could still be afflicted, unaware of the early symptoms of mesothelioma cancer.
The Mesothelioma Resource Online offers a comprehensive list of American naval vessels and military ships that were produced using asbestos, as well as a state-by-state directory of Veterans Affairs center and hospitals to assist service men and women who are suffering from mesothelioma.
Treatment of Mesothelioma
Because of mesothelioma’s great latency period, treating mesothelioma is difficult, but there is hope in recent research and clinical trials. Current medical treatment options include chemotherapy, radiation, and surgery, and most patients choose to undergo a combination of these processes in order to increase their life expectancy. But survivors of mesothelioma have shown that treatment goes beyond hospitals, and that prognosis can be better for patients through healthy dieting, regular exercise and a variety of alternative therapies. Additionally, experimental treatments are available to individual patients depending on their stage progression.
Prognosis
The prognosis for malignant mesothelioma is rarely favorable, which is why early diagnosis is so incredibly important. Yet as mentioned above, there are great strides being taken in the medical and scientific communities to ensure that life expectancy and survival rates continue to climb for patients as researchers continue to find a cure.
Legal Options
People suffering from mesothelioma have almost always been unknowingly exposed to asbestos either in the workplace or through the use of household items that contain the hazardous mineral. After diagnosis, medical bills can be overwhelming and once prognosis is achieved a patient has his family to consider as well. There are legal options available for mesothelioma victims to help achieve just compensation.
Mesothelioma Causes
Mesothelioma Causes
Mesothelioma - a cancer that typically attacks the lungs and abdomen - was profoundly rare until the industrial and commercial use of asbestos expanded in the 20th century. Medical researchers have spent decades investigating the disease and what causes it, and their findings are that asbestos exposure is the primary culprit.
Through studies aimed at pinpointing the exact causes of mesothelioma, researchers gradually learned how being exposed to asbestos triggers cancer.
In March 2009, the International Agency for Research on Cancer reconfirmed that all forms of asbestos can cause mesothelioma - and asbestos exposure is the foremost cause of mesothelioma.
Mesothelioma Cancer
Mesothelioma is an aggressive cancer affecting the membrane lining of the lungs and abdomen.
Malignant mesothelioma is the most serious of all asbestos-related diseases. Although uncommon, mesothelioma cancer is no longer considered rare. The primary cause and risk factor for mesothelioma is exposure to asbestos.
Making a correct mesothelioma diagnosis is particularly difficult for doctors because the disease often presents with symptoms that mimic other common ailments. There is no known cure for mesothelioma, but treatments such as surgery and chemotherapy have helped to improve the typical mesothelioma prognosis.
Pleural mesothelioma (affecting the lung’s protective lining in the chest cavity) represents about three quarters of all mesothelioma incidence. Peritoneal mesothelioma which affects the abdominal cavity and pericardial mesothelioma, which affects the cardiac cavity, comprise the remainder. Testicular mesothelioma is extremely rare and typically presents with metastases of the peritoneal variety. There are three recognized mesothelioma cell-types. Between 50 and 70% of all mesotheliomas are of the epithelial variety. While prognosis is generally poor, it is considered less aggressive than sarcomatoid mesothelioma and biphasic mesothelioma, which comprise the remainder of cell type diagnoses.

The cavities within the body encompassing the chest, abdomen, and heart are surround by a membrane of cells known as the mesothelium. Mesothelial cells assist in general organ functions. The mesothelium is particularly important to organs that are commonly in motion, such as expansion or contraction of the lungs, stomach, or heart. Lubrication from the mesothelial cells allows free range of motion within the body. The mesothelium of the chest, abdomen, and cardiac cavity are called the pleura, the peritoneum, and the pericardium, respectively. Each of these groupings of mesothelial cells are extremely critical to the functions of the body structures which they encompass.
Malignancies (cancerous tumors) occurring within the mesothelial membranes are known as malignant mesothelioma, or simply mesothelioma. Benign tumors of the mesothelium are known to occur, but are much rarer than the more common malignant cancer.
While tumors of the mesothelium were first recognized in the late 18th century, it was not until the middle of the 20th century that this particular cancer was studied and examined with more detail. It was at this time where suspicions of the cancer’s causal relationship with asbestos exposure became more substantiated. A joint research venture through the Department of Thoracic Surgery at the University of the Witswater and/Johannesburg General Hospital in South Africa provided the most compelling evidence of the nexus between asbestos exposure and the development of pleural mesothelioma.
Incidence of mesothelioma is still quite rare, with only 2,500-3000 diagnoses in the United States each year. There was a spike in reported diagnoses between 1970 and 1984, which has been attributed to the latency period between diagnosis and the height of industrial exposures, which occurred roughly 40-60 years prior to this time. Exposure was common in nearly all industries but was particularly common in the WWII-era military industrial cycle, including Navy Shipyards.
Although this cancer is much more common in men over the age of 60 (largely attributed to the industrial exposures within male-dominated industries), mesothelioma in women and children has been described as well. Mesothelioma causes for diagnosis in women and children are mainly attributed to secondary exposure to asbestos, as it was not uncommon for men to bring asbestos back into the home on their body or clothing if proper cleaning facilities were not available on site.
Mesothelioma is diagnosed through a comprehensive combination of biopsy and imaging scans.
Mesothelioma can be a difficult malignancy to diagnose because the symptoms and pathology of the disease closely resemble other respiratory conditions. For this reason, misdiagnosis is not uncommon in mesothelioma patients. Symptoms of mesothelioma include chest pain, chronic cough, effusions of the chest and abdomen, and the presence of blood in lung fluid.
Diagnostic surgeries, including a biopsy, will typically be required to determine the type of malignant cells that are present in the body. Typically a body imaging scan, including a magnetic resonance image (MRI) or computer topography (CT scan) will be required to determine the extent and location of the disease.
Mesothelioma patients are generally referred by their personal physicians to one of the many renowned mesothelioma doctors in the United States. These oncologists are well versed in the disease behavior and pathology and are the most familiar with cutting-edge mesothelioma treatment options. Dr. David Sugarbaker of the Brigham and Women's Hospital, an extension of Harvard University and the Dana Farber Cancer Institute in Boston, MA, is at the forefront of mesothelioma treatment through the International Mesothelioma Program.
While mesothelioma is typically advanced at diagnosis, treatment options are available.
Mesothelioma, while certainly an aggressive disease, is a manageable malignancy. While there is no cure for the cancer, mesothelioma treatment options including surgery, chemotherapy, and radiation therapy are available for many patients. While a combination of Alimta® and Cisplatin is currently the only FDA approved chemotherapy regimen, several clinical trials are currently in progress utilizing other drugs including Gemcitabine and Onconase, with many showing dramatically improved results in certain cancer patients.
Radiation therapy is also utilized, but typically in conjunction with other treatment methods like surgery and chemotherapy. Surgical resection of mesothelioma is possible in early-stage-diagnosed patients. Aggressive surgeries such as extrapleural pneumonectomy can extend survival rates far beyond previously-thought timeframes. Diagnostic and palliative surgeries such as pleurocentesis and pleurodesis are also common in patients of malignant mesothelioma cancer.
Alternative therapies have also been used effectively by many mesothelioma patients to assist in managing symptoms of the disease and conventional treatments. These treatments are mainly preferential but can be extremely valuable to many patients.
Mesothelioma is caused by exposure to asbestos.
Mesothelioma is only caused by exposure to asbestos, though cases have been documented in children or other individuals with no asbestos history. Asbestos is a microscopic and naturally-occurring mineral that lodges in the pleural lining of the lungs and the peritoneal lining of the abdominal cavity. In most cases, several years will pass (up to 60) before mesothelioma develops in those who had been exposed to asbestos.
In many cases, those individuals diagnosed with mesothelioma that have been known to be exposed to asbestos may be eligible for financial compensation from asbestos manufacturers for their illness. Those who have been diagnosed with mesothelioma and were exposed to asbestos should fill out the brief form on this page. We'll rush you a complimentary mesothelioma and asbestos exposure information kit detailing new mesothelioma treatments, active clinical trials, top doctors, as well as how to obtain compensation for asbestos-related health conditions like mesothelioma.

Malignant mesothelioma is a rare type of cancer that occurs in the thin layer of cells lining the body's internal organs, known as the mesothelium. There are three recognized types of mesothelioma. Pleural mesothelioma is the most common form of the disease, accounting for roughly 70% of cases, and occurs in the lining of the lung known as the pleura. Peritoneal mesothelioma occurs in the lining of the abdominal cavity, known as the peritoneum and pericardial mesothelioma originates in the pericardium, which lines the heart.
An individual may be at risk to develop mesothelioma if he or she was exposed to asbestos in the workplace or at home. Mesothelioma is caused by exposure to asbestos and the inhalation of asbestos particles. In most cases, mesothelioma symptoms will not appear in an individual exposed to asbestos until many years after the exposure has occurred. Those with a past asbestos exposure history experiencing symptoms should consult a physician with experience in accurately diagnosing mesothelioma. The earlier mesothelioma is diagnosed, the more likely it is to be caught at an early stage. At earlier stages of mesothelioma progression, more treatment options are available and oftentimes a better prognosis is given. Additional mesothelioma information and statistics can be found in this section.
Mesothelioma Treatment
Once an individual has been diagnosed by a qualified mesothelioma doctor, the next step is to discuss mesothelioma treatment options and to develop a treatment plan. Recent scientific research has produced significant breakthroughs with regard to treatment protocols for mesothelioma patients and more options are now available for managing mesothelioma and supporting improved quality of life. Newly diagnosed mesothelioma patients often have many questions for their doctors about the treatment options that would be most effective for them. Conventional treatment options for mesothelioma include surgery, radiation and chemotherapy. Recently, chemotherapy drugs including Alimta® and Cisplatin have showed promising results in some patients.
Mesothelioma clinical trials as well as experimental treatments are other options that certain mesothelioma patients may be eligible to participate in. Our site features a comprehensive mesothelioma cancer treatment section that includes important information for patients and families. We've included resources on top mesothelioma experts such as Dr. Sugarbaker, as well as a comprehensive list of cancer centers where mesothelioma treatment takes place. Beyond the conventional treatments for mesothelioma, certain alternative therapies may provide assistance to mesothelioma patients. We continually update this section of our site as new mesothelioma treatment information becomes available. Check back often to read about the most recent advances.
Mesothelioma
Mesothelioma (or, more precisely, malignant mesothelioma) is a rare form of cancer that develops from transformed cells originating in the mesothelium, the protective lining that covers many of the internal organs of the body. It is usually caused by exposure to asbestos.[1]
The most common anatomical site for the development of mesothelioma is the pleura (the outer lining of the lungs and internal chest wall), but it can also arise in the peritoneum (the lining of the abdominal cavity), and the pericardium (the sac that surrounds the heart),[2] or the tunica vaginalis (a sac that surrounds the testis).
Most people who develop mesothelioma have worked in jobs where they inhaled asbestos, or were exposed to asbestos dust and fibers in other ways. It has also been suggested that washing clothes of a family member who worked with asbestos increases their risk for developing mesothelioma.[3] Unlike lung cancer, there seems to be no association between mesothelioma and tobacco smoking, but smoking greatly increases the risk of other asbestos-induced cancers.[4] Some people who were exposed to asbestos have collected damages for asbestos-related disease, including mesothelioma. Compensation via asbestos funds or class action lawsuits is an important issue in law practices regarding mesothelioma (see asbestos and the law).
Signs and symptoms of mesothelioma include shortness of breath due to pleural effusion (fluid between the lung and the chest wall) or chest wall pain, and constitutional signs such as unexplained weight loss. The diagnosis may be suspected with chest X-ray and CT scan, but must be confirmed pathologically, either with serous effusion cytology or with a biopsy (removing a sample of the suspicious tissue) and microscopic examination. A thoracoscopy (inserting a tube with a camera into the chest) can be used to acquire biopsy material, and allows the introduction of substances such as talc to obliterate the pleural space (a procedure called pleurodesis), preventing more fluid from accumulating and pressing on the lung. Despite treatment with chemotherapy, radiation therapy or sometimes surgery, the disease carries a poor prognosis. Research about screening tests for the early detection of mesothelioma is ongoing.
