Pleural Mesothelioma: Causes, Symptoms, Diagnosis, Treatment, and Management

Pleural mesothelioma occurs when the pleural cells that cover the outer surface of the lungs grow and multiply abnormally, usually as a result of long-term exposure to asbestos. It is often not diagnosed until symptoms appear and is typically found in advanced stages. Diagnosis is usually made through radiological imaging, biopsy, and other medical tests. Treatment for this type of cancer may include surgery, chemotherapy, radiation therapy, or immunotherapy, depending on the stage of the disease, the patient’s overall health, and other factors. Due to the late-stage diagnosis of pleural mesothelioma, treatment can be challenging, and the prognosis is generally unfavorable.

Causes of Pleural Mesothelioma

Multiple factors are believed to play a role in the development of pleural mesothelioma:

Asbestos Exposure: Exposure to asbestos increases the risk of pleural mesothelioma.

Smoking: Smoking can increase the risk of pleural mesothelioma in individuals exposed to asbestos.

Other Exposures: Exposure to certain chemicals or toxins other than asbestos can also increase the risk of pleural mesothelioma.

Genetic Factors: Some genetic factors are thought to increase the risk of pleural mesothelioma.

Gender and Age: Pleural mesothelioma is more commonly seen in males.

Symptoms of Pleural Mesothelioma

Symptoms of pleural mesothelioma may appear in the advanced stages of the disease and are often initially mild or vague:

  • chest pain
  • shortness of breath
  • cough and sputum
  • rapid weight loss
  • weakness and fatigue
  • blisters on the chest wall
  • fever, hoarseness

Diagnosis of Pleural Mesothelioma

Diagnosing pleural mesothelioma is a complex process that usually requires a series of medical tests and imaging studies:

Patient History and Physical Examination: Describing symptoms and medical history helps doctors evaluate the suspicion of pleural mesothelioma.

X-ray: Chest X-ray is usually the first step in cases of suspected pleural mesothelioma.

Computed Tomography (CT) Scan: CT scans are used to evaluate the presence and extent of tumors by providing more detailed images of the lungs and pleural membrane.

Magnetic Resonance Imaging (MRI): In some cases, MRI scans may be used in addition to CT scans and provide a more detailed view of the extent of tumor spread.

Biopsy: Biopsy may be necessary to confirm the diagnosis.

Fluid Biopsy: In some cases, fluid samples from the chest cavity can be taken.

Blood Tests: Blood tests can be used to measure specific proteins known as tumor markers.

Treatment of Pleural Mesothelioma

Treatment for pleural mesothelioma may involve different methods depending on the stage of the disease, overall health, and patient’s preferences:

Surgery: Surgical intervention aims to remove cancerous tissue.

Pleurectomy: Pleurectomy involves the partial or complete removal of the pleural membrane.

Extrapleural Pneumonectomy: This procedure may involve the complete removal of a lung along with the pleural membrane and is usually performed in advanced stages.

Chemotherapy: Chemotherapy is a treatment method that uses drugs to kill cancer cells or slow their growth.

Radiation Therapy: Radiation therapy aims to target cancer cells using high-energy beams.

Immunotherapy: Immunotherapy is a new approach to cancer treatment that aims to stimulate the immune system to fight against cancer.

Symptom Management: Managing symptoms is important as part of pleural mesothelioma treatment.

Management of Pleural Mesothelioma

The management of pleural mesothelioma involves a closely monitored and treated process by a multidisciplinary healthcare team:

Diagnosis and Staging: After a diagnosis of pleural mesothelioma is made, the stage of the disease should be determined.

Treatment Plan: The treatment plan for pleural mesothelioma should be customized based on the patient’s specific condition.

Surgery: Surgical treatment may be an option depending on the patient’s overall health and tumor stage.

Chemotherapy: Chemotherapy involves the use of drugs that target cancer cells.

Radiation Therapy: Radiation therapy targets cancer cells using high-energy beams.

Immunotherapy: Immunotherapy is a treatment approach used to stimulate the immune system to fight against cancer.

Symptom Management: Symptom management is important during pleural mesothelioma treatment.

Psychological Support: Psychological support and counseling can help patients better manage this process.
