Fertility-sparing treatment has been accepted as a standard treatment for epithelial ovarian cancer in stage IA non-clear cell histology grade 1/grade 2. In order to expand an indication of fertility-sparing treatment, we have started a non-randomized confirmatory trial for stage IA clear cell histology and stage IC unilateral non-clear cell histology grade 1/grade 2. The protocol-defined fertility-sparing surgery is optimal staging laparotomy including unilateral salpingo-oophorectomy, omentectomy, peritoneal cytology and pelvic and para-aortic lymph node dissection or biopsy. After fertility-sparing surgery, four to six cycles of adjuvant chemotherapy with paclitaxel and carboplatin are administered. We plan to enroll 250 patients with an indication of fertility-sparing surgery, and then the primary analysis is to be conducted for 63 operated patients with pathologically confirmed stage IA clear cell histology and stage IC unilateral non-clear cell histology grade 1/grade 2. The primary endpoint is 5-year overall survival. Secondary endpoints are other survival endpoints and factors related to reproduction. This trial has been registered at the UMIN Clinical Trials Registry as UMIN000013380.
