Tumor Grade and Peritoneal Mesothelioma Survival

A new study published in the American Journal of Surgical Pathology highlights the value between tumor grading in peritoneal mesothelioma and prognosis.

Tumor grade is different from mesothelioma tumor stage, which refers to the size or reach of the primary tumor and the level of cancer metastasis. Grading can only be done by looking at cells under a microscope. The study suggests that the level of abnormality seen in the nuclei of tumor cells under the microscope is related to mesothelioma outcomes.

Doctors 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 cases with the lowest tumor grades, were most likely to experience long-term mesothelioma survival.

For more detailed information on the study, titled ‘A Histomorphologic Grading System That Predicts Overall Survival in Diffuse Malignant Peritoneal Mesothelioma With Epithelioid Subtype,’ you can read the complete findings here.
