According to a study by Dr. Tan, median survival for patients with malignant mesothelioma is 11 months. It is almost always fatal. Median survival based on histologic type is 9.4 months for sarcomatous, 12.5 months for epithelial, and 11 months for mixed. Approximately 15% of patients have an indolent course.
His study seems to parallel others with the same result.
This type of cancer normally has a bad outcome regardless of the type of treatments administered.
