Change of Patient-Reported Aesthetic Outcome Over Time and Identification of Factors Characterizing Poor Aesthetic Outcome After Breast-Conserving Therapy: Long-Term Results of a Prospective Cohort Study

We analyzed the change of aesthetic outcome (AO) over time and explored factors characterizing poor AO after breast-conserving surgery (BCS).
This prospective single-center cohort study included 849 patients preoperatively planned for BCS between September 2007 and December 2011. Long-term follow-up was made once in 2013. AO was measured by the Aesthetic Status (AS) of the Breast Cancer Treatment Outcome Scale questionnaire. Clinical, surgical, and pathologic variables were evaluated to identify predictors of poor AO. We applied single factor variance analyses and univariable logistic regression analyses for outcome analysis.
The long-term follow-up rate in 2013 was 73 % (621 nonrecurrent with final BCS). A poor or fair AO was reported in 30 (4.8 %) and 98 (15.8 %) of these 621 patients, respectively. Single factor variance analysis showed a negative impact of higher specimen weight on AO (p < 0.001). Univariable logistic regression analysis revealed the following risk factors for poor AO: radial breast incision [odds ratio (OR) 1.97], periareolar incision (OR 1.85), fishmouth-shaped incision with resection of the nipple–areola complex (OR 8.12), impaired wound healing (OR 3.14), and seroma (OR 2.16). No patient rating her AO as fair or poor shortly after BCS improved in the long-term follow-up.
The incidence of poor AO is relatively rare but increases in the long-term follow-up. Patients experiencing poor AO after BCS are likely to remain unsatisfied with the outcome over time. Factors predicting unfavorable AO can assist preoperative planning with regards to the choice between simple breast conserving techniques or more complex oncoplastic procedures.
