New Mesothelioma Subtype Called Mesothelioma in Situ

A New Mesothelioma Subtype Called Mesothelioma in Situ

The 2015 WHO classification of pleural mesothelioma included three histological subtypes. The new fourth mesothelioma subtype is called mesothelioma in situ. It is a very early form of mesothelioma. Previous studies suggest that it may be a precursor to invasive mesothelioma. If patients know they have it, they may have years to try to keep mesothelioma from developing. Pathologists can tell the difference between the subtypes by looking at the cells under a microscope. Each subtype has a slightly different cell shape, growth pattern, and nuclear characteristics. Four Subtypes of Mesothelioma Pleural mesothelioma is a very rare type of cancer. Only about 2,500 people in the US receive a mesothelioma diagnosis every year. Asbestos inhalation is the primary cause of pleural mesothelioma. Most people with pleural … Continue reading New Mesothelioma Subtype Called Mesothelioma in Situ »

Mesothelioma Subtypes Often Misclassified by Biopsy

New Way to Identify Biopsy Sites to Diagnose Mesothelioma

Pleural biopsy is not perfect when it comes to telling the difference between the three mesothelioma subtypes. But misclassification could lead to shorter survival.  That is the conclusion reached by top mesothelioma researchers in Brescia, Italy.  They compared autopsy records from 134 Italian mesothelioma patients. The patients were either shipyard workers or their spouses. The researchers found that the mesothelioma subtypes identified from biopsy tissue were incorrect a large percent of the time. Misclassification matters because it impacts which mesothelioma treatments doctors choose.  The Three Mesothelioma Subtypes Pleural mesothelioma is an aggressive malignancy on the lung lining. It is caused by exposure to asbestos. Mesothelioma cells fall into three mesothelioma subtypes based on certain cellular characteristics. Pleural mesothelioma is notoriously … Continue reading Mesothelioma Subtypes Often Misclassified by Biopsy »
