Risk of Infertility Related to Adjuvant Chemotherapy for Early Breast Cancer: Oocyte/Embryo Cryopreservation

Not Applicable
Active, not recruiting
Conditions
Breast Cancer
Interventions
Procedure: Controlled ovarian hyperstimulation (COH)
Procedure: Oocyte/embryo freezing
Registration Number
NCT02871167
Lead Sponsor
Centre Oscar Lambret
Brief Summary

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

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

Primary Outcome Measures
NameTimeMethod
Quality of oocytes: total number of oocytes preservedafter 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.

Secondary Outcome Measures
NameTimeMethod
Rate of patients wishing for re-utilization of their frozen gametesup to 10 years after the end of the study or at 43 years old

To assess the number of patients wishing for re-utilization of their frozen gametes

Type of oocytesafter oocyte retrieval (35-36 hours after triptorelin injection)

mature, immature, fractured

Toxicity related to the controlled ovarian stimulation according to NCI CTCAE v4.0 scale24 months

Toxicities will be tabulated with frequencies and percentages by type of adverse events and by grade

Antral Follicular Count (AFC) measurementbaseline, 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

To measure the degree of project completion of subsequent pregnancy(ies)

Disease-free survivalthrough study completion, an average of 5 years

defined as the interval between inclusion and the first occurrence of local, regional or distant relapse, estimated using the Kaplan-Meier method

Serum AMH measurementbaseline, 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 preservedat 44-46 hours post intra-cell sperm injection
