From unraveling the disease’s characteristics to examining treatment options and emerging therapies, this guide serves as an invaluable resource for patients, caregivers, and healthcare professionals alike.
Disease Overview
Pleural mesothelioma is a rare and aggressive type of cancer that occurs in the lining of the lungs and chest cavity. It is caused by exposure to asbestos, a mineral that was commonly used in construction and other industries in the past.
Types of Pleural Mesothelioma
There are three main types of pleural mesothelioma:
- Epithelioid mesothelioma is the most common type, accounting for about 50% of cases.
- Sarcomatoid mesothelioma is a more aggressive type, accounting for about 20% of cases.
- Mixed mesothelioma is a combination of epithelioid and sarcomatoid mesothelioma, accounting for about 30% of cases.
Incidence and Prevalence
Pleural mesothelioma is a rare cancer, with an estimated incidence of 2,000 to 3,000 new cases per year in the United States. The prevalence of pleural mesothelioma is estimated to be 10,000 to 15,000 cases in the United States.
Prognostic Factors
The prognosis of pleural mesothelioma is influenced by a combination of factors, including tumor stage, histology, patient age, gender, and performance status.
Tumor stage is a key prognostic factor. Patients with early-stage disease have a better prognosis than those with advanced-stage disease. Histology also plays a role in prognosis, with epithelioid mesothelioma having a better prognosis than sarcomatoid mesothelioma.
Patient Age and Gender, Pleural mesothelioma prognosis
Patient age and gender can also affect prognosis. Younger patients and female patients tend to have a better prognosis than older patients and male patients.
Performance Status
Performance status is another important prognostic factor. Patients with a good performance status have a better prognosis than those with a poor performance status.
Treatment Options and Prognosis
The treatment options and prognosis for pleural mesothelioma depend on several factors, including the stage of the disease, the patient’s overall health, and the availability of specialized treatment centers. The goal of treatment is to control the growth of the tumor and relieve symptoms, as a cure is often not possible.
Surgical Treatment
- Extrapleural Pneumonectomy (EPP):Involves removing the affected lung, the lining of the chest cavity (pleura), and the diaphragm.
- Pleurectomy/Decortication (P/D):Removes the pleura and any visible tumors, but not the lung.
Non-Surgical Treatments
- Chemotherapy:Uses drugs to kill cancer cells. It can be administered intravenously or directly into the chest cavity (intrapleural chemotherapy).
- Radiation Therapy:Uses high-energy X-rays or other forms of radiation to shrink tumors and relieve pain.
- Immunotherapy:Uses the patient’s own immune system to fight the cancer.
- Targeted Therapy:Uses drugs that target specific molecules involved in cancer growth.
Treatment Choice and Prognosis
The choice of treatment depends on the patient’s specific situation and the expertise of the treating team. The stage of the disease is a major factor in determining prognosis. Patients with early-stage mesothelioma have a better prognosis than those with advanced-stage disease.
Survival Rates and Life Expectancy
The overall survival rate for pleural mesothelioma is low, with a median survival time of around 12-18 months. However, some patients may live for several years or even decades with the disease. Survival rates vary depending on the stage of the disease, the type of treatment received, and the patient’s overall health.
Emerging Therapies and Prognosis
The future of pleural mesothelioma treatment holds promise with the emergence of innovative therapies that aim to improve patient outcomes and prolong survival.

One promising area is immunotherapy, which harnesses the body’s immune system to fight cancer. Immunotherapy drugs, such as pembrolizumab and nivolumab, have shown encouraging results in clinical trials, leading to improved survival rates.
Targeted Therapy
Targeted therapies focus on specific molecules or pathways involved in cancer growth and survival. Drugs like bevacizumab, which targets blood vessel growth, and crizotinib, which inhibits a specific protein, have demonstrated efficacy in treating mesothelioma.
