Overview of Mesothelioma
Mesothelioma is a rare and aggressive form of cancer that affects the lining of the lungs, chest, or abdomen. It is caused by exposure to asbestos, a fibrous mineral that was once commonly used in building materials and insulation.

There are three main types of mesothelioma:
- Pleural mesotheliomais the most common type, accounting for about 75% of cases. It affects the lining of the lungs.
- Peritoneal mesotheliomaaffects the lining of the abdomen. It is less common than pleural mesothelioma, accounting for about 10-15% of cases.
- Pericardial mesotheliomaaffects the lining of the heart. It is the rarest type of mesothelioma, accounting for less than 1% of cases.
The risk of developing mesothelioma is highest among people who have been exposed to asbestos for a long period of time, such as workers in the construction, shipbuilding, and automotive industries. Other risk factors include smoking and exposure to radiation.
The signs and symptoms of mesothelioma can vary depending on the type of mesothelioma. However, some common symptoms include:
- Shortness of breath
- Chest pain
- Abdominal pain
- Swelling in the abdomen
- Weight loss
- Fatigue
Mesothelioma is a serious and often fatal disease. However, there are treatments available that can help to improve the quality of life for patients and extend their survival.
Treatment Options for Mesothelioma
Mesothelioma treatment options depend on the stage of the cancer, the patient’s overall health, and their personal preferences. The main goal of treatment is to relieve symptoms, improve quality of life, and prolong survival.
Types of Surgery for Mesothelioma
Surgery is the primary treatment for mesothelioma. The type of surgery performed depends on the location and stage of the cancer. The most common types of surgery for mesothelioma are:
- Pleurectomy/decortication:This surgery removes the lining of the lungs (pleura) and the lining of the chest wall (pericardium). It is used to treat mesothelioma that is confined to the chest cavity.
- Extrapleural pneumonectomy:This surgery removes the lung, the lining of the lungs, and the lining of the chest wall. It is used to treat mesothelioma that has spread to the lung.
- Cytoreductive surgery:This surgery removes as much of the tumor as possible. It is used to treat mesothelioma that has spread to other parts of the body.
Chemotherapy for Mesothelioma
Chemotherapy is a type of cancer treatment that uses drugs to kill cancer cells. It is often used to treat mesothelioma, a type of cancer that affects the lining of the lungs, abdomen, or heart.

The side effects of chemotherapy for mesothelioma can include:
- Nausea and vomiting
- Hair loss
- Fatigue
- Low blood counts
- Increased risk of infection
Chemotherapy can be an effective treatment for mesothelioma, but it is important to weigh the benefits and risks before starting treatment.
Radiation Therapy for Mesothelioma
Radiation therapy is a treatment option for mesothelioma that uses high-energy radiation to kill cancer cells. It can be used before surgery to shrink tumors, after surgery to kill any remaining cancer cells, or as a standalone treatment for patients who are not eligible for surgery.There
are two main types of radiation therapy used for mesothelioma: external beam radiation therapy and internal radiation therapy. External beam radiation therapy uses a machine to deliver radiation from outside the body, while internal radiation therapy uses radioactive seeds or pellets that are placed inside the body near the tumor.The
side effects of radiation therapy for mesothelioma can include fatigue, nausea, vomiting, diarrhea, skin irritation, and hair loss. The severity of these side effects depends on the dose of radiation and the area of the body being treated.
Targeted Therapy for Mesothelioma
Targeted therapy is a type of cancer treatment that uses drugs to target specific molecules or proteins involved in cancer growth and survival. In the case of mesothelioma, targeted therapy drugs can block the growth and spread of cancer cells by interfering with these specific molecules or proteins.

Types of Targeted Therapy Drugs for Mesothelioma
Several targeted therapy drugs have been approved for the treatment of mesothelioma, including:
- Bevacizumab (Avastin): A monoclonal antibody that blocks the growth of new blood vessels that supply tumors with nutrients.
- Crizotinib (Xalkori): A small molecule inhibitor that targets the ALK protein, which is found in some mesotheliomas.
- Pembrolizumab (Keytruda): An immune checkpoint inhibitor that blocks the PD-1 protein, which helps cancer cells evade the immune system.
Side Effects of Targeted Therapy for Mesothelioma
Targeted therapy drugs can cause side effects, which may vary depending on the specific drug and the individual patient. Common side effects of targeted therapy for mesothelioma include:
- Fatigue
- Nausea and vomiting
- Diarrhea
- Skin rashes
- High blood pressure
- Bleeding or clotting problems
Immunotherapy for Mesothelioma
Immunotherapy is a relatively new treatment option for mesothelioma that uses the patient’s own immune system to fight the cancer. It works by stimulating the immune system to recognize and attack mesothelioma cells.There are different types of immunotherapy drugs used for mesothelioma, including:
- Immune checkpoint inhibitors, which block proteins on the surface of immune cells that prevent them from attacking cancer cells.
- Adoptive cell therapy, which involves removing immune cells from the patient’s body, modifying them in the laboratory to make them more effective at fighting cancer, and then returning them to the patient.
- Oncolytic viruses, which are viruses that have been modified to infect and kill cancer cells.
Immunotherapy can be an effective treatment for mesothelioma, but it can also cause side effects. These side effects can include:
- Fatigue
- Nausea
- Vomiting
- Diarrhea
- Skin rash
- Fever
- Chills
In some cases, immunotherapy can also cause more serious side effects, such as:
- Pneumonitis
- Hepatitis
- Colitis
- Myocarditis
- Neurotoxicity
If you are considering immunotherapy for mesothelioma, it is important to discuss the potential risks and benefits with your doctor.
