Mesothelioma is a cancer caused by the inhalation or ingestion of asbestos fibers. The term mesothelioma refers to all forms of the disease, but there are different sub-types of mesothelioma: epithelioid, sarcomatoid, and biphasic mesothelioma. Because the patient’s prognosis and treatment will be determined by which type of mesothelioma is diagnosed, it is important to understand the differences between the three.
Epithelioid mesothelioma is the most common type of mesothelioma; with research showing as much as 70% of all mesothelioma diagnoses are epithelioid mesothelioma. The word ‘epithelioid’ indicates that the mesothelioma cells are developing from the body’s epithelial cells, which are present in the:
Since epithelioid mesothelioma responds better to treatment, diagnosed asbestos cancer victims can expect a:
Doctors estimate that only 10% of mesothelioma diagnoses are malignant sarcomatoid mesothelioma, which makes it the rarest type. The word ‘sarcomatoid’ indicates that the mesothelioma cells resemble sarcoma, a different form of cancer. Both sarcomatoid mesothelioma and sarcoma develop in the connective tissues of the body, commonly the:
The cells of sarcomatoid mesothelioma and sarcoma appear similar when viewed under a microscope. Because of this, doctors believe that many cases of sarcomatoid mesothelioma are misdiagnosed as sarcoma, particularly when the patient is not aware they were exposed to asbestos. Sarcomatoid mesothelioma:
Biphasic means ‘two parts.' Biphasic mesothelioma means that the mesothelioma is present as two different types, sarcomatoid and epithelioid. Biphasic mesothelioma is more common than sarcomatoid mesothelioma. This is partly due to the way that asbestos enters the body; asbestos that is inhaled or ingested is much more likely to come into contact with epithelioid tissue. Biphasic mesothelioma:
Epithelioid and sarcomatoid develop in different types of tissue, so it is rare for these types of mesothelioma to be mistaken for one another. However, each may be misdiagnosed as a different form of cancer. Biphasic mesothelioma develops in both types of tissue and, therefore, takes on characteristics of both diseases. Where these diseases vary the most is in recommended treatment and patient outcomes.
No matter which diagnosis a patient receives, a mesothelioma diagnosis is devastating. The asbestos attorneys of Clapper, Patti, Schweizer & Mason know this and file lawsuits on behalf of victims and their families against the companies responsible for asbestos exposure, helping affected individuals receive just compensation.
