Ătude Ă©pidĂ©miologique des expositions reprotoxiques des couples infertiles au CPMA, Ă Marseille
Contexte : de nombreuses Ă©tudes ont fait Ă©tat des effets dĂ©lĂ©tĂšres des expositions reprotoxiques environnementales sur la fertilitĂ© masculine ou fĂ©minine ; nĂ©anmoins, le dĂ©pistage des expositions reprotoxiques reste peu rĂ©alisĂ© dans la pratique actuelle.Objectif : identifier les facteurs de risque reprotoxiques (FRR), comportementales, domestiques, environnementales et professionnels chez les patients infertiles.Conception : Ă©tude monocentrique prospective.Patients : Femmes et hommes suivant un traitement en assistance mĂ©dicale Ă la procrĂ©ation (AMP), au CHU de lâhĂŽpital de la Conception Ă Marseille.Intervention : les patients ont rempli un auto-questionnaire pour recueillir des informations sur i) les diffĂ©rents types d'expositions reprotoxiques, et ii) la frĂ©quence et l'intensitĂ© des expositions (approche qualitative et semi-quantitative).Principales mesures des rĂ©sultats : Les FRR identifiĂ©s chez les patients ont Ă©tĂ© classĂ©s en deux catĂ©gories : "reconnu" et "suspectĂ©", dĂ©fini par une recherche bibliographique.RĂ©sultats : sur 1090 patients infertiles vus en consultation pour un traitement dâAMP, nous en avons inclus 810. Les rĂ©sultats montrent que 95,8 % des femmes et 97 % des hommes dĂ©clarent un FRR reconnu ou suspectĂ©. Le nombre de FRR reconnu par patient est gĂ©nĂ©ralement compris entre 1 et 3. Les principaux FRR reconnus auto-dĂ©clarĂ©s chez les hommes sont dus Ă l'exposition aux solvants, Ă la chaleur, aux substances psychoactives et Ă un IMC>25 ; chez les femmes, Ă l'exposition Ă un air intĂ©rieur de mauvaise qualitĂ©, aux substances psychoactives et Ă un IMC>25.Conclusions : presque tous les patients stĂ©riles sont exposĂ©s Ă au moins une substance reconnue ou suspectĂ©e de FRR. Nos rĂ©sultats suggĂšrent que si le dĂ©pistage individuel de chacun Ă©tait fait avant un traitement dâAMP, la plupart des patients pourraient agir sur un nombre de FRR modifiable, dans le but d'augmenter leurs chances de grossesse naturelle et d'amĂ©liorer les rĂ©sultats en AMP

Less than half of men with testicular cancer or lymphomas banked sperm before gonadotoxic treatment in France in 2018
International audienceStudy questionWhat is the proportion of men treated for testicular cancer or lymphoma who banked sperm before gonadotoxic treatment in France?Summary answerIn 2018, 41% of men with testicular cancer and 28% of men with lymphoma banked sperm before gonadotoxic treatment in France.What is known alreadyCancer treatments significantly improved survival rates in men. In Europe, the 5-year survival rate is above 90% for testicular cancer (TC) and Hodgkin lymphoma (HL), which, with Non Hodgkin Lymphoma (NHL), are the most frequent cancers in men of reproductive age. However, surgery, chemotherapy and/or radiotherapy may damage male fertility: between 15% and 30% of men remain permanently infertile after treatment. Since 2011, the French bioethics law recommends and guarantees free access to fertility preservation for all patients needing gonadotoxic treatments. Few international data are available about the rate of male cancer patients who receive sperm cryopreservation before cancer treatment.Study design, size, durationWe analyzed the data of male cancer incidence in 2018 published by the French National Institute of Cancer (INCa), only available and latest French national data, estimated from cancer registers of selected metropolitan departments (Defossez et al. 2019). We organized a survey among the 27 metropolitan centers of the CECOS network (public centers for study and conservation of human eggs and sperm) to collect the annual number of sperm cryopreservations for TC, HL or NHL.Participants/materials, setting, methodsWe compared the number of 0-59 years-old men with TC, HL or NHL in metropolitan France (extracted from 2018 INCa data) and the number of sperm banking for TC, HL or NHL in metropolitan centers of the CECOS network.Main results and the role of chanceINCa estimated that 38,048 new cancers were diagnosed in metropolitan France in 2018 in men aged 0-59 years. TC accounted for 2,630 new cases and lymphomas for 3,913 new cases (943âHL and 2,970 NHL).Twenty-six out of 27 metropolitan CECOS centers answered the survey (96% participation rate): in 2018, 1,079 men banked sperm for TC, 375 for HL and 211 for NHL.In 2018, the fertility preservation rate in metropolitan France was 41% for TC and 28% for lymphomas (51% for HL, and 15% for NHL). The results of our national study are in accordance with Uçar et al. 2020, a monocentric study on 110âTC patients showing a 43% fertility preservation rate, but differ from those of Abdel-Razek et al. 2020, a monocentric study on 59 NHL and 26âHL patients, showing respectively 32% and 14% fertility preservation rates.A limit of our study is to be based on estimated cancer incidence from INCa reports without stratification on age and parenthood; sperm banking activity was measured in the CECOS network, which performs 90% of French male fertility preservation (French Biomedicine Agency 2018 data). This design may induce an underestimation of cancer incidence and of sperm banking activity.Limitations, reasons for cautionOur study did not consider patients who were informed of fertility preservation but did not want to/could not bank ejaculated sperm (azoospermia, sperm collection failure, no-show). In CECOS network, the estimated rate of such patients is 10%.French overseas regions were not studied (lack of INCa data).Wider implications of the findingsOur results suggest that despite the recommendations and facilities offered by the French bioethics law, the male patientsâ pathway for fertility preservation before cancer treatments could be improved. Further study should evaluate if this suboptimal rate of fertility preservation is homogeneous on French territory or related to postal code
Efficient pathway for men fertility preservation in testicular cancer or lymphoma: a cross-sectional study of national 2018 data
International audienceIn 15â49 years-old men, the main cancers are testicular cancer (TC) and lymphomas (L): freezing of ejaculated sperm is primarily used for male fertility preservation (FP) before cancer treatment. Our objective was to analyze the French FP rate in 15â49 years-old men diagnosed with TC or L in 2018. We designed a national descriptive cross-sectional study of sperm banking rate in men with a diagnosis of TC, Hodgkin L (HL) or non-Hodgkin L (NHL). From the French National Cancer Institute (INCa) 2018 data, we extracted the estimated incidence of TC and L in metropolitan France. From the 2018 activity report of CECOS network (Centers for Study and Banking of Eggs and Sperm), we extracted the number of men with TC or L who banked ejaculated sperm. We estimated the proportion of 15â49 years-old men diagnosed with TC or L who banked sperm. Results Among 15â49 years-old men, INCa estimated 38,048 new cancer diagnoses in metropolitan France in 2018: 2,630 TC and 3,913 L (943 HL and 2,970 NHL). The CECOS network provided data from 26/27 metropolitan centers (96% response rate): 1,079 sperm banking for men with TC, 375 for HL and 211 for NHL. We estimated that the 2018 sperm banking rate in France was 41% for TC, 40% for HL, and 7% for NHL. Conclusions To our knowledge, our paper is the first cross-sectional study with multicenter and national data analyzing FP rate in cancer men: it suggests an efficient pathway for men to FP before cancer treatment, compared to previously published studies. Although sperm banking rate in 15â49 years-old men could definitely be improved, further studies should evaluate the information given to patients before gonadotoxic treatments, the factors associated with the absence of sperm banking and whether this lack of referral induces a loss of chance for these men.Chez les hommes de 15 Ă 49 ans, les principaux cancers sont le cancer du testicule (CT) et les lymhomes (L): la congĂ©lation de spermatozoĂŻdes Ă©jaculĂ©s est utilisĂ©e en premiĂšre intention pour leur prĂ©servation de fertilitĂ© (PF) avant traitement du cancer. Notre objectif Ă©tait dâanalyser le taux de PF chez les hommes de 15 Ă 49 ans diagnostiquĂ©s avec un CT ou un L en 2018 en France. Nous avons rĂ©alisĂ© une Ă©tude nationale transversale descriptive du taux de congelation de spermatozoĂŻdes chez les hommes ĂągĂ©s de 15 Ă 49 ans diagnostiquĂ©s avec un CT, un L de Hodgkin (LH) ou un L non-Hodgkinien (LNH). A partir des donnĂ©es de lâInstitut National du Cancer (INCa) de 2018, nous avons extrait lâincidence estimĂ©e de CT et de L en France mĂ©tropolitaine. A partir des donnĂ©es du bilan dâactivitĂ© 2018 de la Federation Française des CECOS (Centre dâEtude et de Conservation des Oeufs et du Sperme), nous avons extrait le nombre dâhommes avec un CT ou un L qui ont congelĂ© leurs spermatozoĂŻdes. Nous avons enfin estimĂ© la proportion dâhommes de 15 Ă 49 ans diagnostiquĂ©s avec un CT ou un L qui ont congelĂ© leurs spermatozoĂŻdes. RĂ©sultats Chez les hommes de 15 Ă 49 ans, lâINCa a estimĂ© en 2018 38 048 nouveaux cas de cancers diagnostiquĂ©s en France mĂ©tropolitaine en 2018: 2 630 CT et 3 913 L (943 LH et 2 970 LNH). Le rĂ©seau des CECOS a produit les rĂ©sultats issus de 26/27 centres mĂ©tropolitains (taux de rĂ©ponse de 96%): 1 079 congĂ©lations de sperme pour des hommes atteints de CT, 375 pour LH et 211 pour LNH. Nous avons estimĂ© que le taux de congelation de spermatozoĂŻdes de 2018 en France Ă©tait de 41% pour le CT, 40% pour le LH et 7% pour le LNH. Conclusions A notre connaissance, notre travail est la premiĂšre Ă©tude transversale multicentrique de donnĂ©es nationales analysant le taux de PF chez les hommes atteints de cancer: il suggĂšre un parcours patient efficace pour la PF des hommes avant traitement dâun cancer, par rapport aux Ă©tudes prĂ©cĂ©demment publiĂ©es. Bien que le taux de PF chez les hommes puisse certainemen ĂȘtre amĂ©liorĂ©, des Ă©tudes futures devraient Ă©valuer lâinformation donnĂ©e aux patients avant traitement gonadotoxique, les facteurs associĂ©s Ă lâabsence de PF et si le dĂ©faut dâadressage au CECOS induit un perte de chance pour ces hommes.
