The low-grade tier had higher overall [mesothelioma] survival...when compared with the high-grade tier...
Raleigh, NC (PRWEB) August 10, 2016
A new study on the relationship between tumor grade and prognosis suggests that the level of abnormality seen in the nuclei of tumor cells under the microscope is related to mesothelioma outcomes. Surviving Mesothelioma has just posted an article on the new research. Click here to read it now.
Doctors at Wake Forest Baptist Health, the University of Mississippi Medical Center, and Memorial Sloan Kettering Cancer Center examined the pathological findings from 46 peritoneal mesothelioma cases. They found that those with a higher tumor grade (greater nuclear abnormality) had the worst odds of mesothelioma survival.
“The low-grade tier had 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 (P=0.002),” writes study author Kari Valente, MD, with Wake Forest Baptist Health in North Carolina.
The findings of this study, published in the American Journal of Surgical Pathology, were similar to the findings of an earlier study on tumor grade and pleural mesothelioma.
“Although tumor grade has been associated with pleural mesothelioma prognosis, this is the first study to link it to peritoneal mesothelioma outcomes, as well,” says Surviving Mesothelioma Managing Editor, Alex Strauss.
Details of the new study and an explanation of tumor grade, including how it differs from tumor stage, can be found in Tumor Grade Helps Predict Peritoneal Mesothelioma Survival, now available on the Surviving Mesothelioma website.
