Abstract

Purpose: This study aimed to evaluate the relationship between pre-operative image-guided large needle core biopsy (LNCB) histopathology results and surgical resection volumes in breast conserving surgery (BCS), with attention to both margin status and cosmetic outcome. Methods: Breast volumes (BV) were calculated using the elliptical cone based formula on mammography images for each patient. Initial resected volume (IRV), final resected volume (FRV), and resected volume ratio (RVR) were calculated and compared according to histopathological diagnosis and cosmetic outcomes. Final pathology results were classified as benign, high risk lesion (HRL), ductal carcinoma in situ (DCIS), or invasive cancer. The cosmetic results were graded based on the Harvard breast cosmesis grading scale. Results: A total of 217 women underwent BCS by the same experienced breast surgeon. The resected volumes (mean, cm3) were higher among patients who underwent LNCB than those who did not (54.3 vs 26.5 ;p=0.005). The LNCB diagnoses were 16% benign, 19% HRLs, 16% DCIS, and 49% invasive cancers. Reexcision rates were 15.6% and 25.8% for DCIS and invasive cancer, respectively. Cosmesis was excellent in 79.8%. Age, pathological tumor size, IRV and FRV were different among the benign, HRLs and carcinoma groups (p= 0.001). Conclusion: The diagnosis of carcinoma by LNCB leads to the planning of a wider resection, but the need for reexcision is no different than less resection. HRLs are best approached with diagnostic excision, as there is no strong evidence that larger resections reduce the incidence of involved resection margins.
