Definition of Epithelioid Mesothelioma
Epithelioid mesothelioma is a rare and aggressive form of cancer that originates in the mesothelial cells, which line the internal organs and body cavities.
Histologically, epithelioid mesothelioma is characterized by polygonal or round tumor cells with eosinophilic cytoplasm and well-defined cell borders. These cells often form glandular or papillary structures, resembling epithelial cells.
Distinction from Other Mesothelioma Subtypes
Epithelioid mesothelioma is distinct from other mesothelioma subtypes, such as sarcomatoid and biphasic mesothelioma, based on the predominant histological features:
- Sarcomatoid mesothelioma:Composed of spindle-shaped cells resembling sarcoma cells.
- Biphasic mesothelioma:Contains both epithelioid and sarcomatoid components.
Incidence and Prevalence
Epithelioid mesothelioma is a relatively rare type of cancer, but it has a high mortality rate. The incidence and prevalence of epithelioid mesothelioma vary worldwide, with higher rates in certain regions and among specific populations.
Globally, the incidence of epithelioid mesothelioma is estimated to be around 1-2 cases per million people per year. However, it is more common in certain countries, such as the United Kingdom, Australia, and New Zealand, where the incidence rates can be as high as 5-10 cases per million people per year.
High-Risk Populations
Certain populations are at higher risk of developing epithelioid mesothelioma. These include people who have been exposed to asbestos, either occupationally or environmentally. Asbestos is a known carcinogen, and exposure to its fibers can increase the risk of developing mesothelioma.
Other risk factors for epithelioid mesothelioma include exposure to radiation, certain chemicals, and smoking.
Prognostic Factors and Survival Rates
The prognosis of epithelioid mesothelioma is influenced by various factors that affect the survival outcomes of patients. These factors provide valuable information in determining the appropriate treatment plan and predicting the course of the disease.

Staging, histological grade, and other clinical variables play a crucial role in assessing the prognosis of epithelioid mesothelioma patients. Understanding these factors helps healthcare professionals make informed decisions regarding treatment strategies and provides patients with a realistic understanding of their expected outcomes.
Staging
Staging is a key prognostic factor in epithelioid mesothelioma. It refers to the extent of the cancer within the body and is determined through imaging tests and biopsies. The stage of the cancer is assigned based on the TNM system, which considers the size and location of the primary tumor (T), the presence of regional lymph node involvement (N), and the presence of distant metastases (M).
- Early-stage (stage I and II)mesothelioma is confined to the chest cavity and has a better prognosis compared to advanced stages.
- Advanced-stage (stage III and IV)mesothelioma has spread beyond the chest cavity and is associated with a poorer prognosis.
Histological Grade
Histological grade is another important prognostic factor. It refers to the microscopic appearance of the tumor cells and is determined by examining a biopsy sample under a microscope. The grade is assigned based on the degree of differentiation of the tumor cells, with well-differentiated tumors having a better prognosis compared to poorly differentiated tumors.
- Well-differentiated tumors(grade I) resemble normal cells and have a slower growth rate.
- Poorly differentiated tumors(grade III) have lost most of their resemblance to normal cells and have a more aggressive growth pattern.
Other Clinical Variables
In addition to staging and histological grade, other clinical variables can also influence the prognosis of epithelioid mesothelioma patients.
- Age: Older patients tend to have a poorer prognosis.
- Gender: Men have a slightly worse prognosis than women.
- Performance status: Patients with a good performance status (able to carry out normal activities) have a better prognosis.
- Comorbidities: The presence of other medical conditions can affect the prognosis.
Treatment Options and Outcomes
Epithelioid mesothelioma treatment plans are tailored to the individual patient’s needs and the stage of their cancer. The primary goal of treatment is to improve survival rates and alleviate symptoms. Treatment options may include surgical resection, chemotherapy, radiation therapy, and targeted therapies, alone or in combination.
Surgical Resection, Epithelioid mesothelioma life expectancy
Surgical resection involves removing the affected tissue, including the tumor and surrounding lymph nodes. This is the preferred treatment option for early-stage epithelioid mesothelioma, when the cancer is localized and has not spread to other parts of the body.
- Efficacy:Surgical resection can be curative in some cases, especially if the cancer is completely removed.
- Side Effects:Surgery can cause pain, scarring, and other complications, depending on the extent of the resection.
Chemotherapy
Chemotherapy uses cytotoxic drugs to kill cancer cells. It can be administered intravenously or orally and is often used in combination with other treatments.
- Efficacy:Chemotherapy can shrink tumors and improve survival rates, but it is not typically curative.
- Side Effects:Chemotherapy can cause a range of side effects, including nausea, vomiting, hair loss, and fatigue.
Radiation Therapy
Radiation therapy uses high-energy radiation to kill cancer cells. It can be delivered externally or internally, using radioactive implants.
- Efficacy:Radiation therapy can shrink tumors and alleviate pain, but it is not typically curative.
- Side Effects:Radiation therapy can cause skin irritation, fatigue, and other side effects, depending on the dose and location of treatment.
Targeted Therapies
Targeted therapies are drugs that specifically target cancer cells by blocking their growth and spread. They are typically used in combination with other treatments.
- Efficacy:Targeted therapies can improve survival rates and alleviate symptoms, but they are not typically curative.
- Side Effects:Targeted therapies can cause a range of side effects, depending on the specific drug used.
Emerging Therapies and Research
Epithelioid mesothelioma is an aggressive cancer with a poor prognosis. However, recent advancements in research have led to the development of promising emerging therapies that offer hope for improved outcomes.One area of active research is immunotherapy, which harnesses the body’s immune system to fight cancer.
Immunotherapy drugs, such as checkpoint inhibitors, work by removing the brakes that normally prevent the immune system from attacking cancer cells. These drugs have shown promising results in clinical trials, and some have been approved for the treatment of epithelioid mesothelioma.Another
promising area of research is gene therapy, which involves using genetic material to treat or prevent disease. Gene therapy approaches for epithelioid mesothelioma aim to correct genetic defects that contribute to cancer development or to introduce new genes that can enhance the immune system’s ability to fight cancer.Personalized
medicine is also playing a role in the development of new treatments for epithelioid mesothelioma. By analyzing the genetic makeup of individual patients, doctors can identify specific targets for therapy. This approach can help to tailor treatments to each patient’s unique needs, improving outcomes and reducing side effects.
