研究概览
简要总结
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.
详细描述
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)

结局指标
主要结局
Quality of oocytes: total number of oocytes preserved
时间窗: after oocyte retrieval (35-36 hours after triptorelin injection)
The distribution of the total number of oocytes preserved will be summarized by the mean (standard error) and median (range) and presented with a 95% confidence interval.
次要结局
- Rate of patients wishing for re-utilization of their frozen gametes(up to 10 years after the end of the study or at 43 years old)
- Type of oocytes(after oocyte retrieval (35-36 hours after triptorelin injection))
- Toxicity related to the controlled ovarian stimulation according to NCI CTCAE v4.0 scale(24 months)
- Antral Follicular Count (AFC) measurement(baseline, at month 3, at month 12, at month 24)
- Number of Spontaneous or medically assisted pregnancy(ies)(up to 10 years after the end of the study or at 43 years old)
- Disease-free survival(through study completion, an average of 5 years)
- Serum AMH measurement(baseline, at the end of the first sequence of chemotherapy, at the last injection of treatment, at Month 3, Month 6, Month 9, Month 12, Month 18 and Month 24)
- Quality of embryos: total number of embryos preserved(at 44-46 hours post intra-cell sperm injection)
