Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The aim of the study is to perform a French multicenter prospective interventional study in order to assess the feasibility and safety of ovarian hyperstimulation for oocyte / embryo cryopreservation in young women with breast cancer. The oncologic and reproductive benefit / risk ratio will be investigated in the oncology and reproductive area.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Medical Oncology:

* Information and collection of consent,
* Imaging staging,
* Inclusion
* Physical examination
* Contraception advise given

Reproductive medicine center:

* Ovarian reserve assessment: serum anti-mullerian hormone (AMH) measurement and antral follicle count (AFC) by ultrasound.
* Serology syphilis, hepatitis B and C, HIV (human immunodeficiency virus). In case of embryo cryopreservation, same serology determination for the men.
* Infertility risk and fertility preservation techniques information.
* In case of agreement, this technique will be done during the time-interval between surgery and chemotherapy
* Fertility preservation (COH stimulation, triggering and oocyte retrieval)

Adjuvant chemotherapy:

* The chemotherapy regimen is 3 FEC (fluorouracil epirubicin cyclophosphamide) 100 followed by standard chemotherapy (according to local practice) +/- Trastuzumab. Adjuvant chemotherapy may only begin after the oocyte retrieval.
* Usual adjuvant chemotherapy is not changed

During chemotherapy:

* Clinical exam before each cycle of chemotherapy
* AMH, AFC at cycle 6

After chemotherapy:

* Usual patient monitoring in expert center :

physical examination at Month 3 (M3), M6 M9 M12 M18 and M24 and mammography at M9 then annual

* AMH at Month 3 (M3), M6 M9 M12 M18 and M24
* AFC at Month 12 (M12) and M24

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Oocyte/embryo cryopreservation

1. Controlled ovarian hyperstimulation (COH)
2. Oocyte/embryo freezing

Group Type EXPERIMENTAL

Controlled ovarian hyperstimulation (COH)

Intervention Type PROCEDURE

After information and consent, patients are addressed to a reproductive medicine center.

The COH will be performed according to a standardized protocol between surgery and the start of adjuvant chemotherapy. Follicular growth will be achieved with an antagonist protocol and by using high dose recombinant FSH (r-FSH). The triggering of the final follicular and oocyte maturation will be obtained by a GnRH (Gonadotropin Releasing Hormone) agonist injection in order to minimize the risk of ovarian hyper-stimulation.

Oocyte/embryo freezing

Intervention Type PROCEDURE

Egg or embryo freezing will be performed according to a standardized protocol: slow-freezing process for embryo; vitrification technique for oocytes. Cryopreserved oocytes and embryos will be stored in the biological bank of each reproductive medicine center (min. 10 years).
