[Fertility preservation, contraception and menopause hormone therapy in women treated for rare ovarian tumors: Guidelines from the French national network dedicated to rare gynaecological cancer]

Abstract

Introduction: Rare ovarian tumors include complex borderline ovarian tumors, sex-cord tumors, germ cell tumors, and rare epithelial tumors. Indications and modalities of fertility preservation, infertility management and contraindications for hormonal contraception or menopause hormone therapy are frequent issues in clinical practice. A panel of experts from the French national network dedicated to rare gynaecological cancers, and of experts in reproductive medicine and gynaecology have worked on guidelines about fertility preservation, contraception and menopause hormone therapy in women treated for ovarian rare tumors.

Methods: A panel of 39 experts from different specialties contributed to the preparation of the guidelines, following the DELPHI method (formal consensus method). Statements were drafted after a systematic literature review, and then rated through two successive rounds.

Results: Thirty-five recommendations were selected, and concerned indications for fertility preservation, contraindications for ovarian stimulation (in the context of fertility preservation or for infertility management), contraceptive options (especially hormonal ones), and menopause hormone therapy for each tumor type. Overall, prudence has been recommended in the case of potentially hormone-sensitive tumors such as sex cord tumors, serous and endometrioid low-grade adenocarcinomas, as well as for high-risk serous borderline ovarian tumors.

Discussion: In the context of a scarce literature, a formal consensus method allowed the elaboration of guidelines, which will help clinicians in the management of these patients.
