Researchers discover ovarian cancer biomarker
A CWRU research team led by Analisa DiFeo, an assistant professor of General Medical Science-Oncology at the Case Comprehensive Cancer Center, found that the biomarker miR-181a is a molecular driver of epithelial ovarian cancer (EOC). The research team also found that elevated levels of miR-181a in ovarian tumors are associated with chemotherapy resistance and disease progression. "By looking at the expression of this microRNA in tumor samples, we get an idea which women may respond to standard chemotherapy and which are at a high risk for recurrence," DiFeo said. "This helps guide treatment decisions and improve survival rates." In the past, researchers have been unable to predict how EOC patients will respond to treatment…
