Abstract
Introduction
Rates of bilateral mastectomy are rising in women with unilateral, nonhereditary breast cancer. We aim to characterize how psychosocial outcomes evolve after breast cancer surgery.
Patients and Methods
We performed a prospective cohort study of women with unilateral, sporadic stage 0–III breast cancer at University Health Network in Toronto, Canada between 2014 and 2017. Women completed validated psychosocial questionnaires (BREAST-Q, Impact of Event Scale, Hospital Anxiety & Depression Scale) preoperatively, and at 6 and 12 months following surgery. Change in psychosocial scores was assessed between surgical groups using linear mixed models, controlling for age, stage, and adjuvant treatments. P < .05 were significant.
Results
A total of 475 women underwent unilateral lumpectomy (42.5%), unilateral mastectomy (38.3%), and bilateral mastectomy (19.2%). There was a significant interaction (P < .0001) between procedure and time for breast satisfaction, psychosocial and physical well-being. Women having unilateral lumpectomy had higher breast satisfaction and psychosocial well-being scores at 6 and 12 months after surgery compared with either unilateral or bilateral mastectomy, with no difference between the latter two groups. Physical well-being declined in all groups over time; scores were not better in women having bilateral mastectomy. While sexual well-being scores remained stable in the unilateral lumpectomy group, scores declined similarly in both unilateral and bilateral mastectomy groups over time. Cancer-related distress, anxiety, and depression scores declined significantly after surgery, regardless of surgical procedure (P < .001).
Conclusions
Psychosocial outcomes are not improved with contralateral prophylactic mastectomy in women with unilateral breast cancer. Our data may inform women considering contralateral prophylactic mastectomy.
