Fertility-sparing surgery for early stage epithelial ovarian cancer.

Discussion of fertility-sparing treatment is an important part of pretreatment counseling for young patients with early epithelial ovarian cancer. As a result of late childbearing nowadays, fertility preservation has become a major issue in ovarian cancer patients. The purpose of this review is to update current knowledge on fertility-sparing treatment for early stage epithelial ovarian cancer, which may be useful for pretreatment counseling for reproductive-age patients. The multicenter study data on the fertility-sparing treatment published by Japan Clinical Oncology Group in 2010 confirmed that fertility-sparing surgery is a safe treatment for Stage IA patients with non-clear cell histology and Grade 1 or 2 and suggested that Stage IA patients with clear cell histology and Stage IC patients with non-clear cell histology and Grade 1 or 2 can be candidates for fertility-sparing surgery followed by adjuvant chemotherapy. In the current review, we added the recent case series and review, and discussed the fertility-sparing treatment on young patients with early epithelial ovarian cancer. We need not to change the proposal by the Japan Clinical Oncology Group study, but we should wait for the results of an ongoing prospective study to strongly recommend the proposal of the Japan Clinical Oncology Group study.
