Objective:
Performing risk-reducing salpingectomy (RRS) at the time of hysterectomy or as a method of tubal ligation has been suggested as a way to reduce the incidence of high grade serous carcinoma (HGSC) of the ovary, since this type of cancer is hypothesized to originate in the fallopian tube. We conducted a survey of Canadian obstetrician-gynaecologists to better understand the uptake and knowledge of implementing this procedure, and to identify barriers to doing so.
Methods:
An anonymous, web-based survey using both quantitative and qualitative methods was sent to obstetrician-gynaecologist members of the Society of Obstetricians and Gynaecologists of Canada and the Society of Gynecologic Oncology of Canada. The survey contained questions about demographics, knowledge and beliefs about RRS, and possible barriers to its implementation in women at average risk for ovarian cancer.
Results:
One hundred ninety-two physicians responded to the survey, a response rate of 25%. Respondents varied in their duration in practice, came from all provinces, and spent a large proportion of their time practising gynaecology. Ninety percent of respondents had heard of RRS; however, 37% were unaware of the evidence supporting the hypothesis that HGSC originates in the fallopian tube, and 38% were unsure whether there would be any population benefit from performing RRS at the time of other gynaecologic surgery. Multiple barriers to implementation were identified.
Conclusion:
Most Canadian obstetrician-gynaecologists responding to our survey were aware of RRS as a possible method to prevent ovarian cancer in women at average risk; however, barriers still exist to widespread implementation. Further research is needed to quantify the population benefit of this procedure.
