Abstract

We assessed the feasibility, patient acceptability of and compliance of a new surveillance strategy for ovarian cancer surveillance in women with BRCA mutations, based on assessments of serum CA125 and HE4 every 4 months (Risk of Ovarian Cancer Algorithm (ROCA) arm), compared to Standard of Care (SOC) surveillance with CA125 blood tests and pelvic ultrasounds every 6 months. Women were recruited 6/13/16-9/11/17 from an integrated health care system in California for this non-randomized prospective cohort study. Women were invited to participate in a novel serum biomarker surveillance strategy using ROCA or they could opt to be in the standard of care control arm with ultrasound and CA 125 every 6 months. Outcomes assessed included compliance, self-reported distress using the Impact of Event Scale (IES) and cancer anxiety using the Cancer Worry Scale. There were 159 women in the ROCA arm and 43 in the SOC arm. Overall, compliance was higher in the ROCA arm (83.2%) than in SOC (51.9%), p < 0.0001. Based on the IES, ROCA arm women reported less feelings about intrusion and avoidance at 12 months compared to baseline; the difference approached significance for intrusion (7.6% vs 4.1% severe, p = 0.057) and was statistically signifi...Continue Reading
