How is Mesothelioma Treated

Like most cancers, the outlook for recovery (prognosis) for people with mesothelioma depends on when the disease is diagnosed and how aggressively it is treated. The treatment plan depends on the stage and location of the cancer, as well as the age and desires of the patient. Treatment generally involves some combination of:
Surgery (to remove the cancer or buildup of fluid)
Radiation (the use of high-energy X-rays to kill cancer cells)
Chemotherapy (drugs that kill cancer cells)
Surgery
Surgery is a common treatment for mesothelioma. The doctor may remove part of the lining of the chest (pleurectomy) or abdomen, and some of the surrounding tissue to get out all of the cancer. Depending on how far the tumor has spread, a lung may also be removed in an operation called a pneumonectomy. Sometimes part of the diaphragm is also removed.
If fluid has collected in your chest or abdomen, your doctor may drain the fluid out by putting a needle into the area and using gentle suction to remove the fluid. Removal of chest fluid for diagnosis or for therapy is called thoracentesis; removal of abdominal fluid is called paracentesis.
Radiation
Radiation therapy uses high-energy X-rays to kill cancer cells or reduce the size of the tumor. Radiation may be administered from a machine outside the body (external radiation therapy) or by inserting materials that produce radiation (radioisotopes) through thin plastic tubes into the cancer area (internal radiation therapy).
Chemotherapy
Chemotherapy uses drugs to kill cancer cells. The drugs may be taken as pills or they may be put into your body by a needle into a vein or muscle. Chemotherapy is called a systemic treatment because the drug enters the blood, travels through the body (that is, through your entire system), potentially killing cancer cells anywhere in the body. For mesothelioma, chemotherapy may also be put directly into your chest (intrapleural chemotherapy). Recent approval of a new program using pemetrexed (Alimta®) and gemcitabine (Gemzar®) have shown beneficial results and good tolerability.
Treatment by stage
Therapies will vary according to the stage of disease, which is determined at the time of diagnosis. If the cancer is localized (found in only one place in the chest), treatment probably will consist of surgery to remove the tumor and surrounding tissue. If the cancer is present in a larger area, treatment may involve more extensive surgery, external radiation and/or chemotherapy.
Treatment for advanced disease may include thoracentesis or paracentesis to reduce discomfort, as well as drugs placed directly into the chest to prevent further fluid buildup. Surgery and radiation may relieve symptoms, and various types of chemotherapy may be used.
Other treatments
Not all patients respond to standard therapy, and some standard treatments have undesirable side effects. For these reasons, new approaches to therapy are currently being evaluated in clinical trials. These new therapies often combine traditional treatments with something entirely new.
Recent studies reported at the American Society of Clinical Oncology showing that combining a new drug called Alimta® (pemetrexed) with cisplatin have shown good results.
Clinical trials
Clinical trials are currently underway to test new drugs and procedures to fight mesothelioma.
