Scientists at three US Cancer Centers have unveiled a new system for predicting survival in people with the epithelioid form of peritoneal mesothelioma. Surviving Mesothelioma has just posted an article on the new system. Click here to read it now.
Doctors at Wake Forest Baptist Health, the University of Mississippi and Memorial Sloan Kettering used a 2011 pleural mesothelioma grading system as a guide. The system involves microscopic examination of peritoneal mesothelioma cells by a pathologist.
“The low-grade tier had a higher overall survival with a median of 11.9 years and 57% at 5 years when compared with the high-grade tier with a median of 3.3 years and 21% at 5 years,” write lead author Karl Valente, MD, in the American Journal of Surgical Pathology.
Mesothelioma patients in the lower tier also tended to live longer without disease progression after cytoreductive surgery and intraperitoneal chemotherapy than did people in the higher tier.
“Until now, there has not been a reliable grading system for peritoneal mesothelioma, largely because few cancer centers have a large enough cohort of this rare asbestos cancer,” says Alex Strauss, Managing Editor for Surviving Mesothelioma. “This is potentially a very important development in the treatment of peritoneal mesothelioma.”
