Abstract Background: Increasing rates of mastectomy, primarily bilateral mastectomy (BMx), have been most dramatic in young women with breast cancer (BC). Impact on long-term quality of life (QOL) is largely unknown. Methods: Between 10/2016-11/2017, we administered the BREAST-Q, a validated patient-reported outcomes measure, to women dx with BC at age ≤40 in a large prospective cohort study. Demographic and treatment information was obtained by surveys and chart review. Mean BREAST-Q scores for each domain (breast satisfaction, physical, psychosocial, and sexual) were compared by surgery types; higher BREAST-Q scores (range: 0-100) indicate better QOL. Linear regression was used to identify predictors of BREAST-Q domain scores. Results: 581 women with stage 0-3 BC completed the BREAST-Q a median of 5.8 years from dx. Median age at dx was 37 (range: 26-40) years; 86% had stage 0, 1 or 2 disease; 28% had breast-conserving surgery (BCS); 72% had mastectomy (Mx), among whom 72% underwent BMx and 89% had reconstruction. Mean BREAST-Q scores (unadjusted) for breast satisfaction, psychosocial, and sexual well-being were lower for patients having unilateral mastectomy (UMx) or BMx compared to BCS; physical function was similar among groups. In multivariate analysis, lower BREAST-Q psychosocial scores were associated with radiation and Mx (UMx or BMx). Lower sexual well-being scores were also associated with Mx. Lower satisfaction with breast scores following radiation were of a clinically significant magnitude (β -8.1 95% CI -11.9- -4.3, p-value 0.03). Lower scores for physical well-being were seen for patients reporting lymphedema and higher for those who had undergone surgery more than 5 years prior. Lower scores across all 4 domains were associated with reported financial distress.

Socio-economic stressors also appear to play a role. When counseling young women about their surgical decisions, knowledge of potential long-term QOL impact is of critical importance.

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.

Abstract BACKGROUND: Arm morbidity, the most reported comorbidity following axillary surgery for breast cancer, is of particular importance in young patients given the longer survivorship period and detrimental effects of arm-morbidity on body image and social-, home- and personal care functions. We assessed the incidence of arm-morbidity stratified by local therapy strategies in young women enrolled in the Young Women's Breast Cancer Study (YWS). PATIENTS AND METHODS: The YWS, a multicenter prospective cohort study, established to explore biological, medical and psychosocial issues in young breast cancer patients, enrolled 1302 women with stage 0-4 breast cancer ≤40 years of age from October 2006 to June 2016. For this analysis, we examined incidence of patient reported arm-swelling or decreased range of motion (ROM) 1-year after diagnosis using relevant items of the CARES-SF. Patients with stage 4 disease (n = 60), those for whom no information on arm-morbidity was available (n=198) and those with bilateral cancer with different local therapy strategies on each side (n=7), were excluded. We performed logistic regression analyses to identify risk factors for arm morbidity. RESULTS: Among 1037 patients (median age 37 years), 13% and 40% reported arm-swelling or decreased ROM, respectively, in the ipsilateral arm at 1-year. 52% (n=539) of patients underwent SLNB and 39% (n=407) ALND. The incidence of arm-swelling was 4% (11/280) in patients who underwent SLNB without RT, 8% (21/252) in patients who underwent SLNB with RT, 20% (13/66) in patients who underwent ALND without RT and 24% (84/337) in patients who received ALND with RT. The incidence of decreased ROM was 21% (59) in patients who underwent SLNB without RT, 34% (86) in patients who underwent SLNB with RT, 33% (22) in patients who underwent ALND without RT and 44% (148) in patients who received ALND with RT. Being overweight, uncomfortable financial status, T4 tumors, ALND and RT were independently associated with an increased risk of arm-swelling. Overweight, mastectomy and RT were independently associated with an increased risk of a decreased ROM Table 1). Results of the logistic regression analyses.

CONCLUSION: Patient reported outcomes reveal high rates of arm-swelling and decreased ROM 1 year after breast cancer diagnosis in a large prospective cohort of young breast cancer survivors. These findings suggest an opportunity for pre-operative education and early intervention for arm impairment in this population.
