Mesothelioma Cell Types – Biphasic Mesothelioma
Biphasic mesothelioma is the second most common form of this cell disease, accounting for 20-40 percent of all known cases. As the name implies, biphasic mesothelioma is a mixture of two cell types of mesothelioma.
Unlike the more common type epithelioid, biphasic mesothelioma cells lack a specific structure. This type of mesothelioma is a mixture of epithelioid and sarcomatoid. While the former has a clearly visible nucleus and is found in uniform, arrangements and tend to be organized in a unique way, the sarcomatoid cells are more oval or oblong in shape and have no readily identifiable core. Although both types of mesothelioma are present in a biphasic tumor, have a tendency to form in different groups are not normally found in the same tumor area.
Diagnosis and Treatment
Mesothelioma cancer is exceptionally difficult to diagnose, which is why a diagnosis of mesothelioma is usually not done until stage 3 or stage 4 of Mesothelioma Mesothelioma is reached. It is important to confirm a history of exposure to asbestos, such as symptoms of mesothelioma are similar to a wide range of respiratory diseases.
Mesothelioma Doctors usually take an x-ray, if there is reason for concern, the patient is referred to a radiology lab, where images are taken more advanced. If abnormal areas are discovered, a tissue sample or biopsy is taken to confirm the diagnosis.
A recent test developed by a Japanese biotech company, called MESOMARK ™, can help pathologists in the diagnosis of mesothelioma at an earlier stage, when it is most treatable.
Treatment in most cases limited to these palliative, since the disease is usually diagnosed too late for surgery of mesothelioma. Mesothelioma is usually treated with a multi-modal therapy involving a combination of radiotherapy and chemotherapy, surgical techniques can be used to relieve symptoms, but in the later stages are usually not effective in treating disease.
