RESUMO
OBJECTIVE: Five to 7% of breast cancers affect women under 40 years old. The survival of these patients has been improved thanks to therapeutic advances, often to the detriment of their fertility. The objective of this study is to evaluate the activity of oncofertility and the future of young women with breast cancer managed at the Montpellier University Hospital. METHODS: This is a retrospective study including women aged from 18 to 43 years-old diagnosed with breast cancer and referred in oncofertility consultation at the Montpellier University Hospital between July 2011 and December 2018. RESULTS: 190 patients were eligible, three refused to participate to the study, hence 187 patients were included. We estimate that only 33% of young breast cancer patients potentially eligible for fertility preservation (FP) benefited from an oncofertility consultation in our region. Of these 187 patients, 58 (31%) underwent ovarian stimulation for oocyte or embryo vitrification. They were significantly younger: 32.9 vs 34.6 years old (P=0.01) and had fewer invaded lymph nodes. A total of 66 cycles were achieved and 11.4 oocytes or 3 embryos were vitrified per patient. The reuse rate was 3.6% with 91% of post cancer pregnancies being spontaneous. CONCLUSION: The oncofertility care network seems effective at the regional level. Enhancing health professionals' awareness and creating a regional register could improve our long-term follow-up.
