Surgery Surgeons work to remove mesothelioma in instances where it is diagnosed at an early stage. Sometimes it isn't possible to remove all of the cancer. In those cases, surgery may help to reduce the signs and symptoms caused by mesothelioma spreading in your body. Surgical options may include:
Surgery to decrease fluid buildup. Pleural mesothelioma may cause fluid to build up in your chest, causing difficulty breathing. Surgeons insert a tube or catheter into your chest to drain the fluid. Surgeons may also inject medicine into your chest to prevent fluid from returning (pleurodesis).
Surgery to remove the tissue around the lung or abdomen. Surgeons may remove the tissue lining the ribs and the lungs (pleurectomy) or the tissue lining the abdominal cavity (peritonectomy) in order to relieve signs and symptoms of mesothelioma.
Surgery to remove as much of the cancer as possible (debulking). If all of the cancer can't be removed, surgeons may attempt to remove as much as possible.
Surgery to remove a lung and the surrounding tissue. Removing the affected lung and the tissue that surrounds it may relieve signs and symptoms of pleural mesothelioma. This procedure also allows doctors to use higher doses of radiation against any remaining mesothelioma, since they won't need to worry about protecting your lung from damaging radiation.
Chemotherapy Chemotherapy uses chemicals to kill cancer cells. Systemic chemotherapy travels throughout the body and may shrink or slow the growth of a pleural mesothelioma that can't be removed using surgery. Chemotherapy may also be used before surgery (neoadjuvant chemotherapy) to make an operation easier or after surgery (adjuvant chemotherapy) to reduce the chance that cancer will return.
Chemotherapy drugs may also be heated and administered directly into the abdominal cavity (intraperitoneal chemotherapy), in the case of peritoneal mesothelioma, or into the chest cavity (intrapleural chemotherapy), in the case of pleural mesothelioma. Using this strategy, chemotherapy drugs can reach the mesothelioma directly without injuring healthy cells in other parts of the body. This allows doctors to administer higher doses of chemotherapy drugs.
Intraperitoneal chemotherapy may also be used to reduce the signs and symptoms of peritoneal mesothelioma that can't be removed through surgery.
Radiation therapy Radiation therapy focuses high-energy beams to a specific spot or spots on your body. Radiation may reduce signs and symptoms in people with pleural mesothelioma. Doctors aim radiation at the entire chest to obtain the best result. However, many sensitive organs are in the chest, such as the heart, lungs, esophagus and spinal cord, so doctors must use low doses of radiation to spare these organs. Radiation therapy is sometimes used after biopsy or surgery to prevent mesothelioma from spreading to the surgical incision.
Radiation therapy is used occasionally in people with peritoneal mesothelioma to reduce signs and symptoms caused by the cancer.
Combination therapy Surgery, chemotherapy and radiation therapy may be combined. This aggressive therapy can be grueling and may not be appropriate for everyone. Younger, healthier people and those with earlier stage mesothelioma may be more able to endure this treatment. Combination therapy has shown the most promise in treating mesothelioma. However, most people will eventually experience a recurrence of this cancer despite aggressive treatment. Combination therapy has been used in both pleural mesothelioma and peritoneal mesothelioma.
Clinical trials Clinical trials are studies of new mesothelioma treatment methods. People with mesothelioma may opt for a clinical trial for a chance to try new types of treatment. However, a cure isn't guaranteed. Carefully consider your treatment options and talk to your doctor about what clinical trials are open to you. Your participation in a clinical trial may help doctors better understand how to treat mesothelioma in the future.
Clinical trials are currently investigating a number of targeted drugs. Targeted drug therapy uses drugs to attack specific abnormalities within cancer cells. Targets being studied in mesothelioma include a substance that cancer cells make to attract new blood vessels to bring the cancer oxygen and nutrients. Another target is an enzyme that helps cancer cells develop resistance to chemotherapy drugs. Researchers hope drugs that target these areas can help kill mesothelioma cells.
Treatment for other types of mesothelioma Pericardial mesothelioma and mesothelioma of the tunica vaginalis are very rare and can be very aggressive. Early-stage cancer may be removed through surgery. Doctors have yet to determine the best way to treat later stage cancers, though. Your doctor may recommend other treatments to improve your quality of life.
