Pleural Mesothelioma Overview

Pleural mesothelioma is a rare and aggressive type of cancer that affects the pleura, a thin layer of tissue that lines the lungs and chest cavity. It occurs when the cells in the pleura become abnormal and begin to grow uncontrollably, forming tumors.

There are three main types of pleural mesothelioma:

  • Epithelioid mesotheliomais the most common type, accounting for about 50-70% of cases. It is characterized by cells that resemble the cells that line the surface of the lungs.
  • Sarcomatoid mesotheliomais a less common type, accounting for about 20-30% of cases. It is characterized by cells that resemble the cells that make up connective tissue.
  • Mixed mesotheliomais a rare type that combines features of both epithelioid and sarcomatoid mesothelioma.

Pleural mesothelioma is a relatively rare cancer, with an estimated incidence of 2-3 cases per million people per year in the United States. It is more common in men than women, and the average age of diagnosis is around 60 years old.

Causes and Risk Factors of Pleural Mesothelioma

Pleural mesothelioma is a rare and aggressive type of cancer that affects the lining of the lungs and chest cavity. The primary cause of pleural mesothelioma is exposure to asbestos, a fibrous mineral that was widely used in various industries.

Asbestos fibers are small and can easily be inhaled. When inhaled, these fibers can become lodged in the pleura, the thin membrane that covers the lungs and lines the chest cavity. Over time, the asbestos fibers can damage the DNA in the pleura cells, leading to the development of mesothelioma.

Other Potential Risk Factors

While asbestos exposure is the primary risk factor for pleural mesothelioma, other factors may also increase the risk of developing this cancer. These include:

  • Smoking:Smoking cigarettes can damage the pleura and make it more susceptible to asbestos-induced damage.
  • Exposure to erionite:Erionite is a type of fibrous mineral that is similar to asbestos and can also cause mesothelioma.
  • Exposure to certain chemicals:Exposure to certain chemicals, such as beryllium and radon, has also been linked to an increased risk of mesothelioma.
  • Genetic factors:Some people may have a genetic predisposition to developing mesothelioma, although this is rare.

The diagnosis of pleural mesothelioma requires the expertise of specialists in thoracic surgery, pathology, and radiology.

Staging and Prognosis of Pleural Mesothelioma

The staging system for pleural mesothelioma helps determine the extent of the cancer and guides treatment decisions. The most commonly used staging system is the TNM system, which considers the size and location of the tumor (T), the presence or absence of lymph node involvement (N), and the presence or absence of distant metastases (M).

The prognosis of pleural mesothelioma patients depends on several factors, including the stage of the cancer, the patient’s age and overall health, and the type of treatment received. The average life expectancy of patients with pleural mesothelioma varies based on these factors, but overall, the prognosis is poor.

In addition to the funeral home and mortgage arrangements, I also needed to find a funeral home in my own hometown. I came across jennings funeral home in jamestown tennessee , which had a great reputation in the community.

Staging System

The TNM staging system for pleural mesothelioma is as follows:

  • T stage: This stage describes the size and location of the tumor.
  • N stage: This stage describes the presence or absence of lymph node involvement.
  • M stage: This stage describes the presence or absence of distant metastases.

The overall stage of the cancer is determined by combining the T, N, and M stages.

Prognostic Factors

The following factors can influence the prognosis of pleural mesothelioma patients:

  • Stage of the cancer: The earlier the stage of the cancer, the better the prognosis.
  • Age and overall health: Younger patients and patients with good overall health tend to have a better prognosis.
  • Type of treatment received: The type of treatment received can also affect the prognosis.

Average Life Expectancy, Pleural mesothelioma life expectancy

The average life expectancy of patients with pleural mesothelioma varies depending on the stage of the cancer and other prognostic factors. According to the American Cancer Society, the average life expectancy for patients with stage I pleural mesothelioma is about 12 months, while the average life expectancy for patients with stage IV pleural mesothelioma is about 6 months.

Treatment Options for Pleural Mesothelioma

Pleural mesothelioma life expectancy

Pleural mesothelioma is a rare and aggressive cancer that affects the lining of the lungs. Treatment options for pleural mesothelioma depend on the stage of the disease, the patient’s overall health, and their personal preferences.


Surgery is the primary treatment option for pleural mesothelioma. The goal of surgery is to remove as much of the tumor as possible. Surgery may be performed through an open incision or through a minimally invasive procedure.

Open surgery involves making a large incision in the chest to access the tumor. Minimally invasive surgery involves making several small incisions and using a camera and surgical instruments to remove the tumor.

Surgery can be curative for some patients with early-stage pleural mesothelioma. However, surgery is not always possible for patients with more advanced disease.


Chemotherapy is a type of drug treatment that uses chemicals to kill cancer cells. Chemotherapy can be given intravenously (IV) or orally.

Chemotherapy is often used in combination with surgery to treat pleural mesothelioma. Chemotherapy can also be used to treat patients who are not eligible for surgery.

Chemotherapy can cause side effects, such as nausea, vomiting, hair loss, and fatigue.

Radiation Therapy

Radiation therapy uses high-energy radiation to kill cancer cells. Radiation therapy can be given externally or internally.

External radiation therapy involves delivering radiation to the chest from outside the body. Internal radiation therapy involves placing radioactive seeds or pellets inside the chest.

Radiation therapy can be used to treat pleural mesothelioma at any stage. Radiation therapy can be used to relieve symptoms, such as pain and shortness of breath.

Radiation therapy can cause side effects, such as skin irritation, fatigue, and nausea.


Immunotherapy is a type of treatment that uses the patient’s own immune system to fight cancer. Immunotherapy can be given intravenously (IV) or orally.

Immunotherapy is often used in combination with other treatments for pleural mesothelioma. Immunotherapy can also be used to treat patients who are not eligible for surgery, chemotherapy, or radiation therapy.

Immunotherapy can cause side effects, such as fatigue, rash, and diarrhea.
