Cell Types of Mesothelioma
Mesothelioma can also be classified based on the type of cells that compose the tumor:
Epithelioid Mesothelioma:
Description: The most common cell type, accounting for 50-70% of cases.
Characteristics: Cells are uniform and structured, making this type more responsive to treatment and associated with a better prognosis.
Sarcomatoid Mesothelioma:
Description: Comprises about 10-20% of cases.
Characteristics: Cells are spindle-shaped and less organized, leading to more aggressive behavior and a poorer prognosis.
Biphasic (Mixed) Mesothelioma:
Description: Contains both epithelioid and sarcomatoid cells.
Characteristics: The prognosis and treatment response depend on the proportion of each cell type within the tumor.
