Introduction
Mesothelioma is a rare and aggressive type of cancer that affects the mesothelium, a thin layer of tissue that lines the lungs, chest cavity, and abdomen. It is most commonly caused by exposure to asbestos, a fibrous mineral that was once widely used in construction and insulation.Mesothelioma
is a relatively rare cancer, with an estimated 3,000 new cases diagnosed each year in the United States. It is more common in men than in women, and the average age at diagnosis is around 60 years old.
Link between Asbestos Exposure and Mesothelioma
Asbestos exposure is the primary risk factor for mesothelioma. When asbestos fibers are inhaled, they can lodge in the lungs and cause inflammation and scarring. Over time, this damage can lead to the development of mesothelioma. The risk of mesothelioma is directly related to the amount of asbestos exposure, and people who have worked in industries that use asbestos are at the highest risk.
Types of Mesothelioma
Mesothelioma is a rare form of cancer that develops in the thin layer of tissue that lines the internal organs. There are three main types of mesothelioma, each affecting a different part of the body:
Pleural Mesothelioma
Pleural mesothelioma is the most common type, accounting for about 75% of all cases. It affects the pleura, which is the membrane that lines the lungs and chest cavity. Symptoms of pleural mesothelioma can include chest pain, shortness of breath, and coughing up blood.
The prognosis for pleural mesothelioma is generally poor, with a median survival time of about 12 months.
Peritoneal Mesothelioma
Peritoneal mesothelioma is less common than pleural mesothelioma, accounting for about 10-20% of all cases. It affects the peritoneum, which is the membrane that lines the abdominal cavity. Symptoms of peritoneal mesothelioma can include abdominal pain, bloating, and weight loss.
The prognosis for peritoneal mesothelioma is also poor, with a median survival time of about 6-12 months.
Pericardial Mesothelioma
Pericardial mesothelioma is the rarest type of mesothelioma, accounting for less than 5% of all cases. It affects the pericardium, which is the membrane that lines the heart. Symptoms of pericardial mesothelioma can include chest pain, shortness of breath, and fatigue.
The prognosis for pericardial mesothelioma is the worst of all types, with a median survival time of less than 6 months.

Prognosis Factors: What Is Mesothelioma Prognosis
Several factors can influence the prognosis of mesothelioma, including the stage of the disease, histologic subtype, patient age and overall health, and treatment options and response.
Stage of Disease
The stage of mesothelioma is one of the most important prognostic factors. The stage refers to the extent of the cancer, including whether it has spread to other parts of the body. Mesothelioma is typically staged using 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).
Histologic Subtype
The histologic subtype of mesothelioma also affects the prognosis. There are three main histologic subtypes of mesothelioma: epithelioid, sarcomatoid, and biphasic. Epithelioid mesothelioma is the most common subtype and has a better prognosis than sarcomatoid mesothelioma. Biphasic mesothelioma has a prognosis that is intermediate between epithelioid and sarcomatoid mesothelioma.

Patient Age and Overall Health
Patient age and overall health can also affect the prognosis of mesothelioma. Younger patients and patients with good overall health tend to have a better prognosis than older patients and patients with poor overall health.
Treatment Options and Response
The treatment options available to a patient with mesothelioma and the patient’s response to treatment can also affect the prognosis. Patients who are able to undergo surgery and who respond well to chemotherapy and/or radiation therapy tend to have a better prognosis than patients who are not able to undergo surgery or who do not respond well to treatment.
Treatment Options
Mesothelioma treatment plans are personalized based on the stage of the cancer, the patient’s overall health, and their preferences. The goal of treatment is to control the disease, relieve symptoms, and improve the patient’s quality of life.
The main treatment options for mesothelioma include:
Surgery
- Extrapleural pneumonectomy (EPP): This surgery removes the entire lung and the lining of the chest cavity.
- Pleurectomy/decortication: This surgery removes the lining of the chest cavity and any tumors that are present.
- Cytoreductive surgery: This surgery removes as much of the tumor as possible to reduce its size and symptoms.
Chemotherapy
Chemotherapy uses drugs to kill cancer cells. It can be given intravenously (IV), orally, or through a port that is placed in the chest.

Radiation Therapy
Radiation therapy uses high-energy beams to kill cancer cells. It can be given externally or internally.
Immunotherapy
Immunotherapy uses the body’s own immune system to fight cancer. It can be given intravenously or through a port that is placed in the chest.
Palliative Care
Palliative care focuses on relieving symptoms and improving the quality of life for patients with advanced mesothelioma. It can include medications, therapies, and other support services.

Survival Rates
The prognosis for mesothelioma is generally poor due to its aggressive nature and lack of early detection methods. Survival rates vary depending on the stage of the disease at diagnosis, the type of mesothelioma, and the patient’s overall health.
Overall, the 5-year survival rate for all stages of mesothelioma is around 10%. However, survival rates can vary significantly based on the stage of the disease.
Stage-Specific Survival Rates
- Stage 1: 70-80% 5-year survival rate
- Stage 2: 40-60% 5-year survival rate
- Stage 3: 20-40% 5-year survival rate
- Stage 4: Less than 5% 5-year survival rate
Factors that Affect Survival Rates
- Age:Younger patients tend to have better survival rates than older patients.
- Overall health:Patients with good overall health are more likely to tolerate treatment and have better survival rates.
- Type of mesothelioma:Pleural mesothelioma has a slightly better prognosis than peritoneal mesothelioma.
- Stage of the disease:Patients diagnosed with early-stage mesothelioma have a better prognosis than those diagnosed with advanced-stage disease.
- Treatment:Patients who receive aggressive treatment, such as surgery, chemotherapy, and radiation therapy, have better survival rates than those who do not receive treatment.
Research and Advancements
Ongoing research efforts and advancements in mesothelioma treatment hold promise for improved prognosis and outcomes. Scientists and researchers are actively exploring various approaches to enhance treatment efficacy and patient survival.
