Background:
Oncoplastic breast surgery (OBS) increases eligibility for breast conserving surgery, though its impact on satisfaction and quality of life remains unclear. Most patients undergo level 1 OBS with removal of <20% of breast volume. However, variable technical approaches may influence patient reported outcomes (PRO).
Methods:
Patients undergoing standardized (sOBS-1) and advanced (aOBS-1) level 1 OBS were prospectively evaluated using the BREAST-Q (BQ) questionnaire pre-operatively and one year post-operatively. Domains included Satisfaction with Breasts (SatBr), Physical Well-being (PhWb), and Psychosocial Well-being (PsyWb). Linear regressions assessed relationships with BQ scores.
Results:
Of 58 patients, 43 underwent sOBS-1 and 15 aOBS-1. Groups were similar in age and BMI, though aOBS-1 patients had larger tumours (median 21 vs 12 mm; p = 0.0001). Tumor size negatively impacted SatBr (p = 0.018). No significant differences were found between groups across all BQ domains.
Conclusion:
Despite larger tumours, aOBS-1 yielded comparable PROs to standardized approaches.
