Protein Marker Linked to Prognosis in Peritoneal Mesothelioma
A cellular marker that helps tell cancer cells to replicate may be used to predict treatment outcomes in people with malignant peritoneal mesothelioma. That conclusion comes from a group of researchers at Australia’s University of New South Wales. The researchers tested tissue samples from 42 mesothelioma patients for the presence of Ki67, a protein associated with cell proliferation. According to the authors, Ki67 has been widely used as a prognostic indicator in other types of cancer, but has not been tested in mesothelioma. The researchers divided the tissue samples into two groups based on their level of Ki67 expression. Those with a Ki67 expression of less than 25% were put in the low category and all samples above that were…
