Fertility preservation before neoadjuvant chemotherapy in a premenopausal breast cancer patient: a case report

Abstract

Neoadjuvant chemotherapy is now a widely accepted treatment modality for operable breast cancer and therefore fertility preservation is an important component of care for young patients with breast cancer. It is critical that oocyte retrieval is completed without delays in the initiation of neoadjuvant chemotherapy. Here we report the case of a 34-year-old woman who was diagnosed with Stage IIA triple-negative breast cancer and underwent ovarian stimulation for fertility preservation prior to the initiation of neoadjuvant chemotherapy. Oocytes were retrieved and in vitro fertilization was conducted before neoadjuvant chemotherapy was started. Upon completion of neoadjuvant chemotherapy, the patient underwent breast surgery. Subsequently, a pathological complete response was achieved. She received a frozen embryo transfer 10 months after breast surgery. The patient became pregnant and delivered a healthy baby.
