Type 2 Diabetes Increases Risk of Death Among Ovarian Cancer Patients, Study Says
Ovarian cancer patients with type 2 diabetes have a greater chance of dying from their cancer -- or from any cause -- than patients without diabetes, according to a meta-analysis of 12 studies. The research, "Diabetes mellitus and long-term mortality of ovarian cancer patients. A systematic review and meta-analysis of 12 cohort studies," was published in Diabetes/Metabolism Research and Reviews. Diabetes, a chronic disease that affects nearly 9 percent of adults worldwide, is characterized by the pancreas' inability to produce enough insulin or to use it effectively. By affecting blood-sugar levels, diabetes can affect the prognosis of other diseases. Some studies suggest it reduces cancer survival rates. To assess whether diabetes influences the mortality rates of ovarian cancer patients, researchers at the Gillings School of Global Public Health at the University of North Carolina at Chapel Hill did a meta-analysis of studies dealing with overall survival, cancer-specific mortality, and mortality from all causes in patients with ovarian cancer and diabetes. The studies, conducted between 1961 and 2012, covered 17,451 ovarian cancer cases. Four studies looked at the median survival times of those with various stages of diabetes. Patients without diabetes survived longer than those with the disease. Ovarian cancer patients with diabetes had a 44 percent higher risk of dying from any cause than those without diabetes. Similarly, they had a 44 percent higher risk of dying from their cancer, although there was a wide statistical range from study to stu
