Brief summary

Interventional research with low risks and constraints, prospective and monocentric on the assessment of long-term fertility in patients who underwent an adjuvant sequential chemotherapy with or without a controled ovarian hyperstimulation. This study follows a previous one called NCT 01614704.

Detailed description

The patients will have a follow-up once a year during ten years beginning at the end of their chemotherapy. They will have a consultation in oncology consisting of: * a clinical exam, * a collection and follow-up of oncological data * a collection of ongoing cancer treatments and a consultation in gynecology consisting of: * a pelvic ultrasound scan (for AFC: Antral Follicle Count) * a biological test (FSH, LH, E2, AMH) * a collection of gynecological data, contraception and reproductive medicine

BIOLOGICALBiological Test

Design outcomes

Primary

MeasureTime frameDescription
Assessment of fertility in terms of cumulative incidence of long-term pregnancy10 years after chemotherapyfor patients who underwent adjuvant sequential chemotherapy of anthracycline and taxane separately, depending on whether or not they have had Controlled Ovarian Hyperstimulation

Secondary

MeasureTime frameDescription
Assessment of fertility in terms of cumulative incidence of births10 years after chemotherapyseparately, depending on whether or not they have had Controlled Ovarian Hyperstimulation
Assessment of fertility - number of pegnancies spontaneous versus assisted10 years after chemotherapydescribing the pregnancy type - number of pegnancies spontaneous versus assisted, with ot without the use of frozen gametes)
Assessment of fertility - pregnancy outcome : miscarriage or single or multiple birth separately10 years after chemotherapydescribing the pregnancy outcome : miscarriage or single or multiple birth separately, depending on whether or not they have had Controlled Ovarian Hyperstimulation
Assessment of the number of patient willing to re-exploit their frozen gametes10 years after chemotherapyfor patients who have had Controlled Ovarian Hyperstimulation
Assessment of the gonadotoxicity of the adjuvant sequential chemotherapy based on anthracyclines and taxanes - AMH rate10 years after chemotherapyin terms of AMH rate depending on whether or not they have had Controlled Ovarian Hyperstimulation
Assessment of the gonadotoxicity of the adjuvant sequential chemotherapy based on anthracyclines and taxanes - Antral Follicle Count10 years after chemotherapyin terms of Antral Follicle Count depending on whether or not they have had Controlled Ovarian Hyperstimulation
Study the long-term carcinologic safety of Controlled Ovarian Hyperstimulation without Letrozole or Tamoxifen co-treatment in terms of survival without relapseAfter chemotherapy ad until disease progression or death regardless of the cause, up to 10 years after chemotherapySurvival without relapse defined by the time frame between the date of surgery and the date of the first recurrence
