Objective: Ovarian cancer screening (OCS) for BRCA1/2 mutation carriers was stopped in our family cancer clinic in 2009 because of its ineffectiveness. The study objective was to investigate the effect of stopping OCS on the timing and uptake of risk-reducing salpingo-oophorectomy (RRSO) and on the percentage of occult cancers in the specimens.
Methods: 419 BRCA1/2 mutation carriers were recruited between January 1999 and June 2013. Uptake, timing and the outcome of the RRSO specimens before stopping OCS (period I) were compared to those after stopping OCS (period II).
Results: The percentage of women undergoing RRSO within the recommended age range increased from 81% to 95%. Receiving DNA test results in period II independently predicted a shorter time interval to RRSO (hazard ratio: 2.48,95% confidence interval: 1.81-3.39). The incidence of detecting occult cancers in RRSO specimens before and after stopping OCS was 1.3% and 1.8%, respectively, and was not statistically significantly different.
Conclusions: The presentation of risk management options to women may influence their decision. The increased patient awareness of the ineffectiveness of OCS could have led to a higher percentage of women undergoing RRSO and doing so more often within the recommended age range.
