Perceptions of risk and reward in BRCA1 and BRCA2 mutation carriers choosing salpingectomy for ovarian cancer prevention

Menée aux Etats-Unis par enquête auprès de 22 femmes porteuses d'une mutation BRCA, cette étude analyse leurs intentions de recourir à une salpingectomie bilatérale prophylactique et évalue le risque perçu de cancer de l'ovaire avant et après avoir subi cette opération (durée médiane de suivi : 3 ans ; âge médian lors de la chirurgie : 39,5 ans)

Résumé en anglais

Salpingectomy with interval oophorectomy has gained traction as an ovarian cancer prevention strategy, but is not currently recommended for high risk women. Nevertheless, some choose this approach. We aimed to understand risk perception and plans for oophorectomy in BRCA1 and BRCA2 (BRCA) mutation carriers choosing salpingectomy for ovarian cancer prevention. This was a longitudinal survey study of BRCA mutation carriers who underwent bilateral salpingectomy to reduce ovarian cancer risk. An initial written questionnaire and telephone interview was followed by annual phone interviews. 22 women with BRCA mutations were enrolled. Median follow-up was three years. The median age at salpingectomy was 39.5 years (range 27–49). Perceived lifetime ovarian cancer risk decreased by half after salpingectomy (median risk reduction 25%, range 0–40%). At final follow-up, five (22.7%) had undergone oophorectomy and five women (22.7%) were not planning to undergo completion oophorectomy. BRCA mutation carriers who had salpingectomy after the recommended age of prophylactic surgery (vs. before the recommended age) were less likely to plan for future oophorectomy (28.6% vs. 66.7%, p = 0.037). All women were satisfied with their decision to undergo salpingectomy with eighteen (81.8%) expressing decreased cancer-related worry. There were no diagnoses of ovarian cancer during our study period. In conclusion, most BRCA mutation carriers undergoing risk-reducing salpingectomy are satisfied with their decision and have lower risk perception after salpingectomy, though some older mutation carriers did not plan on future oophorectomy. Salpingectomy with delayed oophorectomy in BRCA mutation carriers remains investigational and should preferably be performed within a clinical trial to prevent introduction of an innovation before safety has been proven.
