RESUMEN
BACKGROUND: The accurate evaluation of surgical margins holds crucial importance in determining the success of breast-conserving surgery (BCS). The aim of this study was to introduce a novel technique for the positioning of surgical margins in BCS while highlighting its advantages. METHODS: This study included a cohort of breast cancer patients who underwent BCS. The patients were categorized into two groups: one group underwent BCS with the traditional palpation-guided method, and the other with the 3D-MPT technique. The study assessed and compared the feasibility, advantages, and outcomes in terms of quality of life between the two groups. RESULTS: A total of 80 patients were successfully enrolled in the study. No significant differences in clinicopathological features were observed between the two groups. The 3D-MPT technique was found to be feasible and offered several advantages over the palpation-guided method. The utilization of guide wires by experienced radiologists to position the margins before surgery enabled precise and swift specimen removal, resulting in the conservation of valuable time and a reduction in the need for re-excision. Furthermore, the 3D-MPT technique exhibited the potential to enhance cosmetic outcomes and elevate patient satisfaction, particularly in cases with uncertain tumor boundaries detectable by palpation. CONCLUSION: The 3D-MPT technique proves to be an effective and safe approach for reducing tumor positivity rates in initial surgical margins, thereby improving the quality of life for patients undergoing breast-conserving surgery in comparison to the conventional method.
