Is it necessary to do retroperitoneal evaluation in borderline epithelial ovarian tumors?

Objective: Borderline epithelial ovarian tumors have good prognosis without any adjuvant therapy. The advantage of aggressive surgical staging, especially retroperitoneal lymph node sampling is questionable in patients with borderline ovarian tumors. We designed this study to evaluate the necessity of retroperitoneal pelvic and para-aortic lymph node dissection in the treatment of borderline epithelial ovarian tumors.
