Baseline cancer worry and tumor marker testing among earlier-stage breast cancer patients participating in a Choosing Wisely pilot.

Abstract

153 Background: We developed a patient-facing video aimed at raising early breast cancer survivors’ adherence to ASCO’s Choosing Wisely recommendation against surveillance tumor marker testing. To understand the impact of the video on cancer worry regarding recurrence, we surveyed breast cancer survivors before and after viewing the video. Methods: Women with stage I-IIIA breast cancer (N=246) treated at six regional community clinics were surveyed prior to viewing a video at the start of surveillance, then again at follow-up one year later (N=171). Both surveys included the Cancer Worry Scale (CWS-8 items, 4-point Likert scale). Tumor marker (TM) testing during surveillance was collected for 728 patients and linked to surveys among those who provided consent (N=105). Results: Most women (77%) were white age 50+. Among women who completed both questionnaires (N=153), the average CWS summary score was 17.1 at baseline (range=9-29) and 16.9 at follow-up ( p=0.48, range=8-30). Women who did not view the video (A) and those with high baseline cancer worry (B) who viewed the video had similar rates of TM testing (19%) compared to patients with low baseline cancer worry (C) who viewed the video (3%). Cancer worry is highly correlated with the decision to use of TM testing. Viewing an informational video that provided evidence-based advice on follow-up and testing did not impact cancer worry. Enrollment among eligible patients was impacted by challenges to proactively identify and consent patients during their transition to surveillance. Conclusions: Patients with high baseline cancer worry may need different or additional guidance beyond an educational video during their transition to surveillance for breast cancer. [Table: see text]
