Histopathologic tumor spreading in primary ovarian cancer with modified posterior exenteration

摘要

BackgroundTo achieve optimal cytoreduction for advanced-stage ovarian cancer, modified posterior exenteration is the most frequently performed bowel surgery. We assessed the extents of tumor spreading in the rectosigmoid wall and pelvic side wall in modified posterior exenteration specimens during primary debulking surgery (PDS) and interval debulking surgery (IDS) following neoadjuvant chemotherapy, and compared the validity of selecting this surgical procedure in the patients undergoing PDS with that in the patients undergoing IDS.
