There are three different types of mesothelioma cell types. Cell type can influence the aggressiveness of the cancer, treatment protocols, life expectancy, and more.
Epithelioid
- Common Location: Lungs
- Frequency: 65-75% of cases
- Average Life Expectancy: 18-24 months
Epithelioid is the most common cell type found in mesothelioma patients. The epithelioid cells are uniform in shape. When viewed under a high magnification microscope the epithelioid cells appear have a uniform and elongated pattern. The uniform pattern makes these cells easier to distinguish from other cancer cells. Epithelioid cell type is the slowest spreading of the three mesothelioma cell types and typically has the most favorable prognosis.
Sarcomatoid
- Frequency: 15-20% of cases
- Common Location: Lungs, Abdominal Cavity
- Average Life Expectancy: 4-6 months
Sarcomatoid mesothelioma is a much less common cell type than epithelioid. While most sarcomatoids will be found in the lungs it is also associated with the peritoneal (abdominal) mesothelioma. These cells are spindle-shaped and arranged in a chaotic fashion. Sarcomatoid is the most aggressive form of mesothelioma. It originates in the muscles and bones and will often metastasize – making it the most difficult mesothelioma form to treat.
Biphasic
- Frequency: 25%-35%
- Common Location: Lungs, Abdominal Cavity
- Average Life Expectancy: 10-15 Months
Biphasic Mesothelioma cells are a mixture between epithelioid and sarcomatoid. Generally the epithelioid and the sarcomatoid cells are grouped together in different parts of the tumor. Aggressiveness of the malignant cells and the life expectancy largely depend on the amount of epithelioid cells versus sarcomatoid cells. The more the epithelioid cells there are compared to sarcomatoid cells the better the prognosis is for the patient.
