Biphasic mesothelioma describes a condition in which mesothelioma is comprised of both epitheloid and sarcomatoid cancer cells. This form of the disease was once thought to be quite rare, but the number of diagnosed cases has increased over time - possibly because advances in diagnostic tools have enabled more precise histological analysis. It is still, however, less common than is epitheloid mesothelioma.
Like patients with sarcomatoid mesothelioma, patients suffering from the biphasic version of the disease tend to survive for shorter periods of time than do patients with epitheloid mesothelioma. Conventional treatments, including surgery, chemotherapy and radiation, are still options for all three cell types, but patients who have been diagnosed with biphasic or sarcomatoid mesothelioma are often recommended for newer, more experimental treatments in an effort to treat the symptoms of the cancer as aggressively as possible.
As is the case with all forms of the disease, if a patient has received a diagnosis of biphasic mesothelioma, it is important to act quickly in forming a treatment plan. While there is still much to be understood about mesothelioma, conventional cancer data shows that virtually all cancers respond more favorably when treated at an early stage.
