Patient‐reported outcomes post prophylactic risk‐reducing mastectomy: improved breast and psychosocial satisfaction yet poorer physical well‐being

Le résumé fourni par la source

BACKGROUND: Few studies have investigated patient-reported outcomes (PROs) for patients with high breast cancer risk undergoing elective risk reduction mastectomy and reconstruction. These patients incur operative risk in the absence of active cancer, which renders their treatment experience unique. This study aimed to identify longer-term quality of life (QoL) issues that persist in this patient cohort. METHODS: A cross-sectional cohort study assessed PROs in 48 women with high breast cancer risk who attended the Royal Melbourne Hospital Risk Management Clinic, at least 12 months post-mastectomy and reconstruction, with surgery between 2011 and 2020, using the BREAST-Q© Likert surveys. The BREAST-Q© internationally validated QoL instrument scales survey data from 0 (worst) to 100 (best) in 14 domains addressing satisfaction and psychosocial issues. RESULTS: There was higher overall breast and psychosocial satisfaction, with scores of 11 and four, respectively, yet lower chest, abdomen and sexual well-being scores with 14, three and four, respectively, in contrast to normative BREAST-Q© data from >1000 women without prior breast cancer or breast operations. High average scores >90 were found for patient satisfaction with surgical, medical and office staff. Twenty-one patients had an average score of 63 for satisfaction with breast implants, while 27 patients post-DIEP had average scores >72 for abdominal well-being, appearance and overall outcomes. Higher mean QoL outcomes were found with DIEP flap in all domains, compared with breast implant reconstruction. CONCLUSION: QoL assessment with PROs 12 months post-risk reduction mastectomy and reconstruction demonstrated higher psychosocial well-being, yet highlights physical implications, with patients experiencing reduced chest, abdomen and sexual well-being, compared with normative BREAST-Q© control data. Higher mean QoL outcomes were found with DIEP flap compared with breast implant reconstruction. PROs studies can identify unmet needs and facilitate change in service provision.
