Open Biopsy Better for Diagnosing Mesothelioma Subtype

Open surgical biopsy – called thoracotomy – appears to be the best way to get an accurate diagnosis of mesothelioma subtype. Mesothelioma is a fast-growing malignancy caused by asbestos exposure.  Epithelial mesothelioma is the most common subtype, followed by sarcomatoid and biphasic.  Determining which subtype a patient has is an important prognostic indicator and can help guide doctors in making treatment decisions. But mesothelioma itself is notoriously difficult to diagnose, and determining subtype can be equally tricky. To help determine the most accurate diagnostic method, a group of Australian scientists evaluated the records of 83 patients who underwent a surgical procedure called extrapleural pneumonectomy (EPP) for mesothelioma between 1994 and 2009. A panel of pathologists reviewed the specimens collected during EPP and … Continue reading Open Biopsy Better for Diagnosing Mesothelioma Subtype »
