Contraception in breast cancer survivors from the FEERIC case-control study (performed on behalf of the Seintinelles research network).

OBJECTIVE: To compare the prevalence of contraception in breast cancer (BC) patients at risk of unintentional pregnancy (i.e. not currently pregnant or trying to get pregnant) and matched controls. STUDY DESIGN: The FEERIC study (Fertility, Pregnancy, Contraception after BC in France) is a prospective, multicenter case-control study, including localized BC patients aged 18-43 years, matched for age and parity to cancer-free volunteer controls in a 1:2 ratio. Data were collected through online questionnaires completed on the Seintinelles research platform. RESULTS: In a population of 1278 women at risk of unintentional pregnancy, the prevalence of contraception at study inclusion did not differ significantly between cases (340/431, 78.9%) and controls (666/847, 78.6%, p = 0.97). Contrarily, the contraceptive methods used were significantly different, with a higher proportion of copper IUD use in BC survivors (59.5% versus 25.0% in controls p < 0.001). For patients at risk of unintentional pregnancy, receiving information about chemotherapy-induced ovary damage at BC diagnosis (OR = 2.47 95%CI [ 1.39-4.37] and anti-HER2 treatment (OR = 2.46, 95% CI [ 1.14-6.16]) were significantly associated with the use of a contraception in multivariate analysis. CONCLUSION: In this large French study, BC survivors had a prevalence of contraception use similar to that for matched controls, though almost one in five women at risk of unintentional pregnancy did not use contraception. Dedicated consultations at cancer care centers could further improve access to information and contraception counseling.

Pregnancy, fertility concerns and fertility preservation procedures in a national study of French breast cancer survivors.

RESEARCH QUESTION: What are the real-life oncofertility practices in young women diagnosed with breast cancer? DESIGN: The FEERIC (FErtility, prEgnancy, contRaceptIon after breast Cancer in France) study is a web-based cohort study launched with the French collaborative research platform Seintinelles. The current work is based on the enrolment self-administered questionnaire of 517 patients with prior breast cancer diagnosis, free from relapse and aged 18 to 43 years at inclusion (from 12 March 2018 to 27 June 2019). RESULTS: Median age at breast cancer diagnosis was 33.6 years and 424 patients (82.0%) received chemotherapy. Overall, 236 (45.6%) patients were offered specialized oncofertility counselling, 181 patients underwent at least one fertility preservation procedure (FPP); 125 (24.2%) underwent one or more FPP with material preservation (oocytes n = 108, 20.9%; embryos n = 31, 6.0%; ovarian cryopreservation n = 6, 1.2%) and 78 patients received gonadotrophin-releasing hormone agonists (15.1%). With a median follow-up of 26.9 months after the end of treatments, 133 pregnancies had occurred in 85 patients (16.4%), including 20 unplanned pregnancies (15.0%). Most of the pregnancies were natural conceptions (n = 113, 87.6%), while 16 (12.4%) required medical interventions. For the planned pregnancies, median time to the occurrence of an ongoing pregnancy was 3 months. Patients who had an unplanned pregnancy reported lower rates of information on the consequences of the treatments on fertility (P = 0.036) at diagnosis. CONCLUSIONS: Most of the patients were not offered proper specialized oncofertility counselling at the time of breast cancer diagnosis. Naturally conceived pregnancies after breast cancer were much more frequent than pregnancies resulting from the use of cryopreserved gametes. Adequate contraceptive counselling seems as important as information about fertility and might prevent unplanned pregnancies.

Faced to an undetermined ovarian mass on ultrasound, an MRI is recommended and the ROMA score (combining CA125 and HE4) can be proposed (grade A). In case of suspected early stage ovarian or fallopian tube cancer, omentectomy (at least infracolonic), appendectomy, multiple peritoneal biopsies, peritoneal cytology (grade C) and pelvic and para-aortic lymphadenectomy are recommended (grade B) for all histological types, except for the expansive mucinous subtype where lymphadenectomy may be omitted (grade C). Minimally invasive surgery is recommended for early stage ovarian cancer, if there is no risk of tumor rupture (grade B). Adjuvant chemotherapy with carboplatin and paclitaxel is recommended for all high-grade ovarian or Fallopian tube cancers, stage FIGO I-IIA (grade A). In case of ovarian, Fallopian tube or primitive peritoneal cancer of FIGO III-IV stages, thoraco-abdomino-pelvic CT scan with injection (grade B) is recommended. Laparoscopic exploration for multiple biopsies (grade A) and to evaluate carcinomatosis score (at least using the Fagotti score) (grade C) are recommended to estimate the possibility of a complete surgery (i.e. no macroscopic residue). Complete medial laparotomy surgery is recommended for advanced cancers (grade B). It is recommended in advanced cancers to perform para-aortic and pelvic lymphadenectomy in case of clinical or radiological suspicion of metastatic lymph node (grade B). In the absence of clinical or radiological lymphadenopathy and in case of complete peritoneal surgery during an initial surgery for advanced cancer, it is possible not to perform a lymphadenectomy because it does not modify the medical treatment and the overall survival (grade B). Primary surgery is recommended when no tumor residue is possible (grade B). After a complete first surgery, it is recommended to deliver 6 cycles of intravenous (grade A) or to propose intraperitoneal (grade B) chemotherapy, to be discussed with patient, according to the benefit/risk ratio. After a complete interval surgery for a FIGO III stage, the hyperthermic intra peritoneal chemotherapy (HIPEC) can be proposed in the same conditions of the OV-HIPEC trial (grade B). In case of tumor residue after surgery or FIGO stage IV, chemotherapy associated with bevacizumab is recommended (grade A).
