Summary

This is a multicenter hospital-based prospective cohort study conducted in institutions with known expertise in performing oocytes/embryo freezing for fertility preservation. The study aims at refining the understanding of the efficacy and safety of controlled ovarian stimulation with or without letrozole in young women with newly diagnosed breast cancer who are candidates to receive (neo)adjuvant chemotherapy.

Conditions

  • Breast Neoplasm Malignant Female

Interventions

DRUG

Letrozole

Patients start ovarian stimulation protocol according to their menstrual cycle phase at enrollment (standard or "random start"). Ovarian stimulation includes gonadotropins administration in a GnRH antagonist protocol. "Standard Protocol": letrozole is orally administered (5mg/d) from cycle day 2-3 throughout the ovarian stimulation with gonadotropins protocol until ovulation triggering. "Random start" protocol: letrozole is administered throughout the stimulation together with gonadotropins. GnRH antagonist is administered at cycle day 7 or as soon as at least one follicle reaches 12-14 mm. Oocytes are collected 36h after ovulation triggering with GnRH agonist.

OTHER

standard-stimulated cohort

Patients start ovarian stimulation protocol according to their menstrual cycle phase at enrollment (standard or "random start"). Ovarian stimulation includes gonadotropins administration in a GnRH antagonist protocol. "Standard Protocol": Gonadotrophins started from cycle day 2-3 throughout the ovarian stimulation until ovulation triggering. "Random start" protocol: Gonadotrophins started at any time of the cycle and throughout the stimulation. GnRH antagonist is administered at cycle day 7 or as soon as at least one follicle reaches 12-14 mm. Oocytes are collected 36h after ovulation triggering with GnRH agonist.
