Decrease of dysmenorrhoea with hormonal treatment is a marker of endometriosis severity.

RESEARCH QUESTION: Is a decrease in dysmenorrhoea after suppressive hormonal therapy a marker of the endometriosis phenotype and of greater disease severity? DESIGN: Retrospective observational cohort study conducted in a French university hospital, between January 2004 and December 2019. Non-pregnant women aged younger than 42 years, who tested for dysmenorrhoea relief after suppressive hormonal therapy before surgery, and who had histological confirmation of endometriosis, were included. The comparisons were carried out according to the results of the suppressive hormonal test. RESULTS: Of the 578 histologically proven endometriosis patients with preoperative pain symptoms, the rate of dysmenorrhoea decrease after suppressive hormonal therapy was 88.2% (n = 510). These patients had a higher incidence of deep infiltrating endometriosis (DIE) intestinal lesions (45.7% [233/510] versus 30.8% [21/68], P = 0.01) and an increased rate of multiple DIE lesions (two or more) (72.8% [287/394] versus 56.4% [22/39], P = 0.02). After multivariate analysis, decrease of dysmenorrhoea after suppressive hormonal therapy remained significantly associated with the severe DIE phenotype (adjusted OR 3.9, 95% CI 2.0 to 7.6, P < 0.001). CONCLUSION: In women with endometriosis, a decrease of dysmenorrhoea after suppressive hormonal therapy is associated with the DIE phenotype and is a marker of greater severity.

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.
