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.

Grading System That Predicts Overall Survival in Diffuse Malignant Peritoneal
Mesothelioma With Epithelioid Subtype,’ you can
