Embarking on the journey of pleural mesothelioma treatment, we delve into the complexities of this rare and aggressive cancer. Join us as we explore the latest advancements, treatment modalities, and supportive care strategies that empower patients and their families in navigating this challenging path.
Definition and Overview of Pleural Mesothelioma
Pleural mesothelioma is a rare and aggressive cancer that forms in the thin layer of tissue that lines the lungs and chest cavity (pleura). It is caused by exposure to asbestos, a mineral fiber that was once commonly used in construction and insulation materials.
There are three main types of pleural mesothelioma:
- Epithelial mesothelioma: This is the most common type, accounting for about 70% of cases. It starts in the cells that line the surface of the pleura.
- Sarcomatoid mesothelioma: This type is less common, accounting for about 20% of cases. It starts in the cells that make up the connective tissue of the pleura.
- Biphasic mesothelioma: This type is the rarest, accounting for about 10% of cases. It has features of both epithelial and sarcomatoid mesothelioma.
The risk of developing pleural mesothelioma is highest in people who have been exposed to asbestos for a long period of time. Asbestos fibers can be inhaled or ingested, and they can become lodged in the lungs or pleura. Over time, these fibers can damage the DNA in cells, leading to the development of cancer.
The signs and symptoms of pleural mesothelioma can vary depending on the type of mesothelioma and the stage of the disease. Some common symptoms include:
- Shortness of breath
- Chest pain
- Cough
- Fatigue
- Weight loss
- Night sweats
- Fever
If you have any of these symptoms, it is important to see your doctor right away. Early diagnosis and treatment of pleural mesothelioma is important for improving the chances of survival.
Diagnostic Procedures for Pleural Mesothelioma
Diagnosing pleural mesothelioma involves a combination of imaging techniques, biopsies, and other diagnostic tests. These procedures help identify the presence and extent of the disease.
Imaging Techniques
- X-rays:Chest X-rays provide initial images of the lungs and pleura, detecting abnormalities like pleural thickening or masses.
- CT scans (computed tomography):CT scans use X-rays to create cross-sectional images of the chest, providing more detailed views of the pleura and surrounding structures.
- MRI (magnetic resonance imaging):MRI scans use magnetic fields and radio waves to produce detailed images of the pleura and surrounding tissues, highlighting any abnormal growths or fluid accumulation.
Biopsy
A biopsy is a procedure where a small sample of tissue is removed from the pleura for examination under a microscope. This is the definitive method to confirm a diagnosis of pleural mesothelioma.
Other Diagnostic Tests
- Blood tests:Blood tests can detect certain biomarkers associated with mesothelioma, such as elevated levels of mesothelin or soluble mesothelin-related peptides.
- Pleural fluid analysis:Fluid from the pleural space can be analyzed for the presence of mesothelioma cells or other indicators of the disease.
Treatment Options for Pleural Mesothelioma
Treatment for pleural mesothelioma depends on the stage of the disease, the patient’s overall health, and their preferences. The primary goal of treatment is to remove or destroy as much of the cancerous tissue as possible, while preserving lung function and minimizing side effects.

There are several different treatment options for pleural mesothelioma, including surgery, chemotherapy, radiation therapy, targeted therapy, and immunotherapy. The best course of treatment for each patient will be determined by their individual circumstances.
Surgical Treatment
Surgery is the primary treatment for pleural mesothelioma. The type of surgery performed will depend on the stage of the disease and the patient’s overall health. The two most common types of surgery are extrapleural pneumonectomy and pleurectomy/decortication.
- Extrapleural pneumonectomyinvolves removing the entire lung and the lining of the chest cavity (pleura). This is the most aggressive type of surgery for pleural mesothelioma, but it is also the most effective.
- Pleurectomy/decorticationinvolves removing the lining of the chest cavity (pleura) and any visible tumors. This is a less aggressive surgery than extrapleural pneumonectomy, but it is also less effective.
Chemotherapy, Pleural mesothelioma treatment
Chemotherapy is a type of drug treatment that uses chemicals to kill cancer cells. Chemotherapy can be used to treat pleural mesothelioma before or after surgery. It can also be used to relieve symptoms of the disease.
The most common chemotherapy drugs used to treat pleural mesothelioma are cisplatin, pemetrexed, and carboplatin.
Radiation Therapy
Radiation therapy uses high-energy beams of radiation to kill cancer cells. Radiation therapy can be used to treat pleural mesothelioma before or after surgery. It can also be used to relieve symptoms of the disease.
The most common type of radiation therapy used to treat pleural mesothelioma is external beam radiation therapy. This involves delivering radiation beams to the chest from outside the body.

Targeted Therapy
Targeted therapy is a type of drug treatment that uses drugs to target specific molecules or proteins that are involved in the growth and spread of cancer cells. Targeted therapy can be used to treat pleural mesothelioma that has spread to other parts of the body.
The most common targeted therapy drug used to treat pleural mesothelioma is bevacizumab (Avastin).
Immunotherapy
Immunotherapy is a type of treatment that uses the patient’s own immune system to fight cancer. Immunotherapy can be used to treat pleural mesothelioma that has spread to other parts of the body.
The most common immunotherapy drug used to treat pleural mesothelioma is pembrolizumab (Keytruda).
Prognosis and Management of Pleural Mesothelioma
The prognosis of pleural mesothelioma depends on several factors, including the stage of the disease, the patient’s age and overall health, and the type of treatment received. The median survival time for patients with pleural mesothelioma is approximately 12-18 months.
However, some patients may live for several years or even decades with the disease.

Palliative care is an important part of the management of pleural mesothelioma. Palliative care focuses on relieving the symptoms of the disease and improving the patient’s quality of life. Treatment options for pleural mesothelioma include surgery, chemotherapy, radiation therapy, and immunotherapy.
The best treatment option for a particular patient will depend on the stage of the disease and the patient’s overall health.
Support Groups and Resources
There are a number of support groups and resources available for patients and families affected by pleural mesothelioma. These groups can provide information about the disease, treatment options, and coping with the emotional challenges of living with mesothelioma.
