Understanding Malignant Epithelioid Mesothelioma: Causes, Symptoms, and Treatment

Malignant epithelioid mesothelioma is a rare and aggressive form of cancer that primarily affects the mesothelial cells lining the lungs, abdomen, heart, or testicles.


This condition is commonly associated with exposure to asbestos, a mineral once widely used in industries such as construction, insulation, and shipbuilding. In this article, we will delve into the details of malignant epithelioid mesothelioma, including its causes, symptoms, and available treatment options.

  1. Causes of Malignant Epithelioid Mesothelioma:

The primary cause of malignant epithelioid mesothelioma is exposure to asbestos fibers. When asbestos particles are inhaled or ingested, they can become lodged in the mesothelial tissue, leading to chronic inflammation and genetic damage over time. However, it’s important to note that not all individuals exposed to asbestos will develop mesothelioma, and there may be other contributing factors yet to be fully understood.

  1. Symptoms and Diagnosis:

Malignant epithelioid mesothelioma symptoms can vary depending on the affected area, but some common signs include:

  • Persistent cough or wheezing
  • Shortness of breath
  • Chest or abdominal pain
  • Fatigue
  • Unexplained weight loss
  • Fluid buildup in the affected area (pleural effusion or ascites)

Diagnosing malignant epithelioid mesothelioma typically involves a comprehensive evaluation, including a review of medical history, physical examination, imaging tests (X-ray, CT scan, MRI), and a biopsy to analyze the tissue for cancerous cells. Given its rarity and similarity to other conditions, obtaining an accurate diagnosis may require consultation with a specialized medical professional.

  1. Treatment Options:

The treatment approach for malignant epithelioid mesothelioma depends on various factors, including the stage of the disease, overall health, and patient preferences. Treatment options may include:

  • Surgery: Surgical procedures such as pleurectomy/decortication (removal of affected tissue) or extrapleural pneumonectomy (removal of the lung and surrounding tissue) may be performed in early-stage cases to remove tumors and improve prognosis.
  • Radiation Therapy: High-energy radiation is used to target and destroy cancer cells, either as a primary treatment option or in combination with surgery or chemotherapy. It may also be used to alleviate symptoms and reduce tumor size in advanced cases.
  • Chemotherapy: Anti-cancer drugs are administered orally or intravenously to destroy cancer cells throughout the body. Chemotherapy is commonly used to shrink tumors, relieve symptoms, and improve overall survival rates.
  • Targeted Therapy: This approach involves the use of drugs that specifically target certain genetic mutations or pathways in cancer cells, minimizing damage to healthy cells. Targeted therapy is still being studied and may be used in conjunction with other treatments or in clinical trials.
  • Immunotherapy: Immunotherapy utilizes drugs that boost the body’s immune system to recognize and attack cancer cells. It shows promise in treating mesothelioma and is often used in clinical trials or as a part of personalized treatment plans.
  1. Prognosis and Support:

Malignant epithelioid mesothelioma is often diagnosed at an advanced stage, which can impact the prognosis. However, advancements in treatment options and ongoing research offer hope for improved outcomes. It is crucial for patients to seek care from specialized medical centers and engage in comprehensive support services, including counseling, support groups, and palliative care, to manage symptoms and enhance their quality of life.
