=== Radiation ===
===Chemotherapy===
Chemotherapy is one of the main treatments for mesothelioma. Many people are not diagnosed until their mesothelioma is advanced and cannot be removed with surgery. In these cases, chemotherapy is used to treat the disease and relieve symptoms.


For patients with localized disease, and who can tolerate a radical surgery, radiation is often given post-operatively as a consolidative treatment. The entire hemi-thorax is treated with radiation therapy, often given simultaneously with chemotherapy. This approach of using surgery followed by radiation with chemotherapy has been pioneered by the thoracic oncology team at Brigham & Women's Hospital in Boston. <ref name="sugarbaker">"Resection margins, extrapleural nodal status, and cell type determine postoperative long-term survival in trimodality therapy of malignant pleural mesothelioma: results in 183 patients." by D. Sugarbaker in ''J Thorac Cardiovasc Surg'' (1999) volume 117, pages 54-63 {{Entrez Pubmed|9869758}}.</ref>  Delivering radiation and chemotherapy after a radical surgery has led to extended life expectancy in selected patient populations with some patients surviving more than 5 years. As part of a curative approach to mesothelioma, radiotherapy is also commonly applied to the sites of [[chest drain]] insertion, in order to prevent growth of the tumor along the track in the chest wall.
Chemotherapy is the use of anti-cancer (cytotoxic) drugs to treat cancer. It is usually a systemic therapy

Although mesothelioma is generally resistant to curative treatment with [[radiotherapy]] alone, palliative treatment regimens are sometimes used to relieve symptoms arising from tumor growth, such as obstruction of a major blood vessel. Radiation therapy when given alone with curative intent has never been shown to improve survival from mesothelioma.

In February 2004, the United States [[Food and Drug Administration]] approved [[pemetrexed]] (brand name Alimta) for treatment of malignant pleural mesothelioma. Pemetrexed is given in combination with [[cisplatin]]. [[Folic acid]] is also used to reduce the side-effects of pemetrexed.

=== Immunotherapy ===
The most common chemotherapy drugs used to treat mesothelioma are:
Treatment regimens involving immunotherapy have yielded variable results. For example, intrapleural inoculation of [[Bacillus Calmette-Guérin]] (BCG) in an attempt to boost the immune response, was found to be of no benefit to the patient (while it may benefit patients with [[bladder cancer]]). Mesothelioma cells proved susceptible to in vitro lysis by LAK cells following activation by [[interleukin-2]] (IL-2), but patients undergoing this particular therapy experienced major side effects. Indeed, this trial was suspended in view of the unacceptably high levels of IL-2 toxicity and the severity of side effects such as fever and cachexia.  Nonetheless, other trials involving interferon alpha have proved more encouraging with 20% of patients experiencing a greater than 50% reduction in tumor mass combined with minimal side effects.

Although a single drug may be used, better responses to chemotherapy occur when a combination of drugs are given for mesothelioma. The most common chemotherapy combinations used to treat mesothelioma are:


This technique permits the administration of high concentrations of selected drugs into the abdominal and pelvic surfaces. Heating the chemotherapy treatment increases the penetration of the drugs into tissues. Also, heating itself damages the malignant cells more than the normal cells.

carboplatin and pemetrexed

Intrapleural chemotherapy can be used to control pleural effusions.
intraperitoneal chemotherapy
Chemotherapy drugs are injected into the peritoneal space or peritoneal cavity (space between the abdominal organs and the membrane lining the abdominal wall).
This is the way chemotherapy is most often given to treat peritoneal mesothelioma. Peritoneal mesothelioma usually remains confined to the peritoneal cavity until late in the course of the disease. Giving drugs directly into the peritoneal cavity greatly enhances the concentration of drugs in that area and limiting side effects to the rest of the body.
Sometimes regional chemotherapy is given right after surgery (in the operating room) or soon afterwards.
 
Some of the drugs used as regional chemotherapy to treat mesothelioma include:
 
cisplatin

Overview

Medical Therapy

The treatment for mesothelioma depend on various factors, which include:[1]

  • Location of the mesothelioma
  • Stage
  • Resectability of the tumor
  • Type of symptoms
  • Overall health and performance status
  • Performance status
  • Age

Supportive Care

Concern Supportive Care
Loss of appetite Small amounts of high-calorie foods or fluids, having smaller, more frequent meals, and nutritional supplements can be helpful. Anti-emetic drugs can be used to control nausea and vomiting. Cold foods may be better tolerated and using plastic cutlery can help if foods have a metallic taste. When appropriate, medicines may be prescribed to help increase appetite. Cachexia can occur in people whose mesothelioma is very advanced.
Shortness of breath Pleural effusion is common with pleural mesothelioma, but can also occur with some peritoneal mesothelioma. Treatment options for pleural effusion may include:

Relaxation and breathing exercises may help with problems breathing. Oxygen therapy may be ordered to help relieve difficulty breathing.

Ascites Peritoneal mesothelioma can cause ascites. Paracentesis may be done to relieve symptoms. Another option is to insert catheter to drain the fluid from the abdomen.
Pain People with advanced mesothelioma may experience pain because the tumor grows into surrounding nerves and organs. The amount of pain often increases as the cancer advances. Pain may be managed by:
  • External beam radiation therapy: Palliative radiation therapy may help relieve pain by shrinking tumors that press on nerves or other organs.
  • Palliative surgery: Palliative surgery or procedures are not used to remove the tumor, but are done to relieve pain or other problems, such as pleural effusion or ascites. Palliative surgery or procedures may include:
  • Pain-relieving medications: Pain medications are used, especially for advanced mesothelioma.
Fatigue Poor appetite and trouble breathing can also make fatigue worse. It can be hard to cope when you are feeling very tired and don’t have a lot of energy, especially for a while after treatment or if the cancer is advanced.
Bowel obstruction Bowel obstruction can occur in people with peritoneal mesothelioma. A bowel obstruction can cause abdominal pain, nausea, vomiting, and an inability to pass feces. Resting the bowel by not having anything to eat or drink, or feeding through a nasogastric tube placement may help, but surgery to remove the obstruction may be necessary.
Coping with advanced cancer Mesothelioma is often diagnosed at an advanced stage. People with advanced mesothelioma are offered palliative care. This is a special type of care that focuses on making the person as comfortable as possible, relieving symptoms, providing support and improving or maintaining the person’s quality of life.
Financial concerns People with mesothelioma may have financial concerns as a result of their illness. There are special services or benefits to help workers (and their families) who have developed mesothelioma from occupational exposure to asbestos. Conditions about exposure and legal processing of claims for asbestos-related cancers can differ by province or territory.

Chemotherapy

Chemotherapy is one of the main treatments for mesothelioma. Many people are not diagnosed until their mesothelioma is advanced and cannot be removed with surgery. In these cases, chemotherapy is used to treat the disease and relieve symptoms.

Chemotherapy is the use of anti-cancer (cytotoxic) drugs to treat cancer.

Chemotherapy drugs

The most common chemotherapy drugs used to treat mesothelioma are:

cisplatin (Platinol AQ) carboplatin (Paraplatin, Paraplatin AQ) an antifolate drug pemetrexed (Alimta) raltitrexed (Tomudex) gemcitabine (Gemzar) Gemcitabine may be given to people who cannot have platinum-based (cisplatin or carboplatin) combination chemotherapy. vinorelbine (Navelbine) This drug may be also given to people who cannot have platinum-based combination chemotherapy or who have been treated previously with platinum-based combination chemotherapy. Although a single drug may be used, better responses to chemotherapy occur when a combination of drugs are given for mesothelioma. The most common chemotherapy combinations used to treat mesothelioma are:

cisplatin and an antifolate drug cisplatin and pemetrexed – most common combination used cisplatin and raltitrexed carboplatin (Paraplatin, Paraplatin AQ) and an antifolate drug Carboplatin may be used instead of cisplatin, especially in older adults because it causes less kidney and nerve problems than cisplatin. Drug combinations may include: carboplatin and pemetrexed carboplatin and raltitrexed cisplatin and gemcitabine carboplatin and gemcitabine These combinations of drugs are given intravenously for 3–6 cycles. In some cases, they are given until the disease progresses.

Regional chemotherapy

Regional (intracavitary) chemotherapy for mesothelioma may include:

intrapleural chemotherapy Chemotherapy drugs are injected through a chest tube or catheter into the pleural cavity (the space between the membranes lining the lung and chest wall). It is used to treat pleural mesothelioma. Intrapleural chemotherapy can be used to control pleural effusions. intraperitoneal chemotherapy Chemotherapy drugs are injected into the peritoneal space or peritoneal cavity (space between the abdominal organs and the membrane lining the abdominal wall). This is the way chemotherapy is most often given to treat peritoneal mesothelioma. Peritoneal mesothelioma usually remains confined to the peritoneal cavity until late in the course of the disease. Giving drugs directly into the peritoneal cavity greatly enhances the concentration of drugs in that area and limiting side effects to the rest of the body. Sometimes regional chemotherapy is given right after surgery (in the operating room) or soon afterwards.

Some of the drugs used as regional chemotherapy to treat mesothelioma include:

cisplatin mitomycin (Mutamycin) doxorubicin (Adriamycin) Regional chemotherapy drugs are sometimes heated before they are given (hyperthermic chemotherapy) to help them work better.
