Age and cancer treatment factors influence patient-reported outcomes following therapeutic mammoplasty and contralateral symmetrisation for the treatment of breast cancer.

Background: Oncoplastic surgery for breast cancer has increased in popularity over the last few years, with oncological safety confirmed in several studies. There are, however, limited published data on patient-reported outcomes from this surgical approach. This study assessed patient-reported outcomes of satisfaction following therapeutic mammoplasty and contralateral symmetrisation (TMCS) as part of breast cancer treatment in relation to other patient and treatment factors.

Methods: The validated BREAST-Q™ breast reduction module was sent to all surviving patients who had no documented cancer recurrence and had undergone TMCS in NHS Tayside between August 2013 and August 2017. The Q-score was used to analyse data and correlate with patient clinical information, surgical, pathology and treatment factors. Ethical approval was granted by the University of Dundee ethics committee.

Results: The patient response rate to the study was 64.5% (60 of 93 patients), with a mean age of 59 years (range 41-75 years). In all domains, patients reported high levels of satisfaction with outcomes. There were strong correlations between domains with the exception of physical symptoms. Younger patients reported poorer outcomes in domains that related to satisfaction with outcomes of surgery, psychosocial aspects, sexual function and physical symptoms. Treatment with chemotherapy and/or trastuzumab and lymph node positivity were associated with poorer outcomes in a number of domains.

Conclusions: Our results demonstrate that patients report high levels of satisfaction after TMCS, but this is influenced by age. Patient-reported outcomes that include physical and psychosocial appear to be more strongly influenced by medical treatments than surgery.
