Introduction
Cancer is a life-threatening disease that has become a significant public health concern worldwide. Malignant mesothelioma, a rare and aggressive form of cancer, is caused by exposure to asbestos fibers and has a poor prognosis. The incidence of this disease is on the rise, and there is a need for effective treatment options to fight this cancer. In this article, we will discuss the treatment options available for malignant mesothelioma, including the latest therapies and clinical trials.
What is Malignant Mesothelioma?
Malignant mesothelioma is a form of cancer that develops in the mesothelial cells, which line the lungs, abdomen, heart, and other organs. The primary cause of this cancer is exposure to asbestos fibers, which are small and nearly invisible. These fibers can be inhaled or ingested, leading to the formation of cancerous growths. Mesothelioma can affect three different areas: the pleura (the thin membrane that lines the lungs and chest cavity), the peritoneum (the thin membrane that lines the abdomen), and the pericardium (the thin membrane that surrounds the heart).
What are the Treatment Options for Malignant Mesothelioma?
There are several treatment options available for malignant mesothelioma, including surgery, chemotherapy, radiation therapy, and immunotherapy. Treatment decisions will depend on the type and stage of the cancer, the patient’s overall health, and the goals of treatment. Mesothelioma is often detected at an advanced stage, making it difficult to treat effectively. Early detection can improve survival rates and increase treatment options.
1) Surgery
Surgery is the primary treatment for mesothelioma and involves removing the tumor and surrounding tissue. There are several surgical procedures for mesothelioma, including pleurectomy/decortication (P/D), extrapleural pneumonectomy (EPP), and cytoreduction with heated intraperitoneal chemotherapy (HIPEC).
Pleurectomy/Decortication (P/D)
P/D involves removing the pleura lining and any visible tumor. This surgery is less invasive than EPP and is suitable for patients with early-stage mesothelioma. This surgery aims to relieve symptoms and prolong life, not cure cancer.
Extrapleural Pneumonectomy (EPP)
EPP involves removing the affected lung, pleura lining, and surrounding tissue. This surgery is more invasive than P/D but may provide a better chance of long-term survival. EPP is typically reserved for patients with early-stage mesothelioma.
Cytoreduction with heated intraperitoneal chemotherapy (HIPEC)
HIPEC is a surgical technique used to treat peritoneal mesothelioma. It involves removing visible tumors from the abdomen and then pouring hot chemotherapy drugs directly into the abdominal cavity. This treatment can improve survival rates and is increasingly used in clinical trials.
2) Chemotherapy
Chemotherapy is a treatment that uses drugs to kill cancer cells. Chemotherapy drugs can be given orally or intravenously. Chemotherapy is often used in conjunction with surgery to reduce the risk of cancer recurrence.
Systemic Chemotherapy
Systemic chemotherapy is given through an IV and travels throughout the body. This treatment can cause side effects, such as hair loss, nausea, and fatigue.
Intraperitoneal Chemotherapy
Intraperitoneal chemotherapy is delivered directly into the abdominal cavity, providing a concentrated dose of chemotherapy drugs to the affected area. This treatment is reserved for peritoneal mesothelioma and can improve survival rates.
Newer Chemotherapy Drugs
There are several new chemotherapy drugs currently being tested in clinical trials, including immunotoxins and targeted therapies. These drugs may offer more effective treatments with fewer side effects.
3) Radiation Therapy
Radiation therapy uses high-energy radiation to kill cancer cells. This treatment is often used in combination with surgery and chemotherapy to shrink tumors and reduce cancer recurrence.
External Beam Radiation
External beam radiation involves directing high-energy radiation at the tumor from outside the body. This treatment typically involves several sessions and can cause side effects such as fatigue, skin irritation, and nausea.
Internal Radiation
Internal radiation involves placing radioactive material directly into the body near the tumor. This treatment is only suitable for certain types of mesothelioma and is typically reserved for palliative care.
4) Immunotherapy
Immunotherapy is a type of cancer treatment that uses the body’s immune system to fight cancer. This treatment works by stimulating the immune system to attack cancer cells. Several immunotherapy drugs are currently used to treat mesothelioma, including pembrolizumab and nivolumab.
Clinical Trials
There are several ongoing clinical trials researching new and innovative treatments for mesothelioma. These trials test new drugs, therapies, and treatments to find new ways to fight cancer.

Frequently Asked Questions (FAQs)
What is the prognosis for malignant mesothelioma?
The prognosis for mesothelioma depends on several factors, including the stage of cancer, the patient’s overall health, and the type of mesothelioma. The survival rate for mesothelioma is low, with an average life expectancy of 12-21 months after diagnosis.
How is mesothelioma diagnosed?
Mesothelioma is typically diagnosed through a combination of imaging tests, such as CT scans and MRIs. A biopsy is used to confirm the diagnosis and determine the type and stage of cancer.
Is mesothelioma curable?
Mesothelioma is rarely curable, but early detection and treatment can improve survival rates and prolong life.
Can mesothelioma be prevented?
The primary cause of mesothelioma is exposure to asbestos. Avoiding exposure to asbestos can reduce the risk of developing mesothelioma.
What are the side effects of treatment?
The side effects of treatment depend on the type of treatment and the patient’s overall health. Common side effects include nausea, fatigue, hair loss, and pain.
Can mesothelioma recur after treatment?
Yes, mesothelioma can recur after treatment. Follow-up care is important to monitor the disease and detect any recurrence.
What are clinical trials?
Clinical trials are research studies that test new treatments, drugs, and therapies for cancer. These trials are designed to find new and innovative ways to fight cancer.
How do I know if I qualify for a clinical trial?
Your doctor can help determine if you are a suitable candidate for a clinical trial. The eligibility criteria for clinical trials depend on several factors, including the type and stage of cancer, age, and overall health.
