Abstract
BACKGROUND The Geometric Compensation Technique (GCT) and the Split Reduction Technique (SRT) enables breast conserving surgery (BCS) in selected patients with breast cancer initially candidates to mastectomy. METHODS Observational study of patients with breast cancer who underwent GCT consecutively treated. Evaluated retrospectively: indications, clinical characteristics, surgical features and recurrences. Cosmesis were evaluated prospectively by the BCCT.core software, Harris/Harvard and Garbay scales. Descriptive statistics were performed, chi-square test was used to compare aesthetic outcomes; Kappa and Weighted Kappa test was used to assess agreement between the postoperative evaluations; Kaplan-Meier model for follow-up and recurrence. A systematic review was carried out using PRISMA methodology. RESULTS Thirty-six patients were evaluated, 26 (72.2%) with medium/large breasts with or without ptosis, seven (19.4%) with small breasts with or without ptosis, a profile undergoing GCT not previously identified in the literature. The mean tumor clinical size was 3.65 ± 1.59 cm. 34 (94.4%) patients underwent GCT. Mean follow-up time was 36.6 ± 16.8 months, with no local recurrences. According to BCCT.core, the postoperative aesthetic was good in 17 (51.5%) patients and 11 (33.3%) was reasonable. In the systematic review, 3.584 articles were evaluated, 20 articles were selected, 243 patients undergoing GCT were found, with several indications for BCS instead of mastectomy, with high rates of free margins, low recurrence and good aesthetic outcomes. CONCLUSION GCT, an oncologically safe and aesthetically satisfactory option, has been extended to patients with small and medium breasts with ptosis, large tumors to breast volume or in unfavorable resection sites, initially candidates for mastectomy.
