Abstract P2-14-03: Longitudinal changes in psychosocial health in young women following breast cancer surgery: Results from a multi-center cohort study

Abstract

Abstract Background: Young women with breast cancer (BC) are increasingly choosing contralateral prophylactic mastectomy (CPM), yet little is known about the impact of surgical choices on quality of life (QOL) and psychological health. Using a large, prospective cohort of young women with BC, we sought to evaluate psychosocial outcomes following surgery. Methods: Among participants of the Young Women's BC Study, a multi-center cohort of women dx'd with BC at age ≤40, we identified women with Stage 0-3 unilateral BC who had surgery and completed surveys that included measures of QOL (CARES) and psychological health (HADS). Linear mixed-effects models were fit to assess changes from 1 to 3 years (yrs) post-dx in anxiety, depression, psychosocial, body image, and sexual scores. Adjusted (stage, hormone receptor status, chemotherapy, age) means were estimated and differences compared (Bonferroni adjusted p-values) between CPM vs breast conserving surgery (BCS) and unilateral mastectomy (UM) at 1, 2, and 3 yrs. Results: Of 863 women, 30% had BCS, 24% UM, 46% CPM. Median age at dx was 37 (range: 22-40). Of women who had UM/CPM, 84% had reconstruction. Among women who had CPM, mean body image (p=.02), psychosocial (p<.0001), sexual (p<.0001), and depression p=.0007) scores decreased, indicating improvement, from yr 1 to 2 but remained stable from yr 2 to 3 (Table). Anxiety decreased from yr 1 to 2 for women who had BCS (p=.0007) and M (p=.03), and from yr 2 to 3 for women who had CPM (p=.003). Body image scores did not change significantly between any time points among women who had M or BCS. Overall change trajectories for sexual (p=.03) and anxiety scores (p=.008) differed by surgery. Compared to BCS and UM, psychosocial scores were higher in women who had CPM at 1 yr (p<.05) and remained higher compared to BCS at 2 yrs (p=.04). Anxiety was higher among women who had CPM vs UM at 1 and 2 yrs (p<.01), vs BCS at 2 yrs (p=.004). Depression was higher among women who had CPM vs UM in yr 1 (p=.05). By yr 3, there were no significant differences in anxiety, depression, and overall psychosocial scores between groups. Compared to BCS, women who had CPM had higher sexual and body image scores (p<.01), indicating worse QOL, at all timepoints. Compared to UM, women who had CPM had higher sexual scores at 1 and 3 yrs (p<.05) and body image scores at 3 yrs (p=.02). Conclusions: While psychosocial health improves over time, differences by surgery persist, with women who have CPM experiencing more sexual and body image issues compared to women who undergo BCS or M in the years following surgery. Given that surgical choices may be affected by distress experienced before or at dx, ensuring young women receive adequate support when making surgical decisions as well as after surgery is warranted.
