Mert I, et al. - Considering the FIGO staging consensus agreement from 2012 says that bowel mucosal invasion for epithelial ovarian cancer (EOC) should be allocated to stage IV disease, researchers examined how recto-sigmoid colonic invasion influences survival in ovarian cancer by analyzing patients having recto-sigmoid resection to achieve complete gross resection for stage IIIC/IV EOC between 2003 and 2011. They analyzed 85 patients with a mean age of 64.5 years and identified no prognostic significance of depth of recto-sigmoid colon wall invasion. A higher tendency for upper abdominal or miliary disease was reported among EOC patients with superficial bowel invasion. The findings do not support assigning mucosal recto-sigmoid invasion to stage IV disease.
