Combined Patients and Medical Related Cosmetic Breast Cancer Outcomes—A Preferred Approach to Outcomes Assessment

摘要

Introduction: Reducing positive margins and need for re-excision yet maintaining cosmesis is key in breast cancer surgery. This study describes the evaluation of early outcomes of a combined cosmetic assessment programme following breast conservation surgery (BCS). Methods: An ethically approved prospective study was conducted at Letterkenny University Hospital and a 15-month timeframe was chosen. All consecutive patients undergoing conservative breast surgery with complete local excision, from July 2015 to October 2016, were entered into the study. Patients undergoing mastectomy and reconstruction with either implant or autologous tissue were not included. 41 patients undergoing BCS were analysed. Objective and subjective cosmetic evaluations were carried out. Assessments used were the Breast Cancer Conservative Treatment—cosmetic results [BCCT.core 2.0] Software, a panel of 4 experts in breast surgery and the Breast Cancer Treatment Outcome Scale (BCTOS). Demographic and pathological data, breast excision weight, % breast volume excised (BVE), margin positivity, complications and re-excision were documented. Data was expressed as mean and standard deviation for normally distributed data and medians and inter quartile range for non-normal data. Scores were also dichotomised to excellent/good and fair/poor and results were analysed. Results: 41 patients’ mean age is 55 ± 13 years. Mean breast volume was 768.3 cm3 ± 440;BVE weighed 78.6g ± 42.6 (18.9 - 214.4) and %BVE 11.3% ± 5.2% (5.1 - 23.3). Re-excision rate was 2/41 (4.9%) all for positive margins. 0/41 infections or haematomas occurred. Cosmetic status of 10 - 14 days post surgery was excellent or good by BCCT.core Software 78%, Expert panel 82.9%, BCTOS scale (92.7%), and fair or poor in 22%, 17.1% and 7.3% respectively. Conclusion: This study successfully evaluated objective and subjective cosmetic related outcomes following breast conserving surgery, incorporating both patient and surgeon in these assessments. The encouraging results show that despite low re-excision rates, acceptable cosmetic outcomes were achieved.
