Abstract

Abstract: Aim: There is no consensual indication for surgical resection after diagnosis on per-cutaneous biopsy of borderline breast lesions (B3). We evaluate under-evaluation rate of per-cutaneous biopsy and predictive factors of under-evaluation. We analyze accuracy of reported decision-making tools. Methods: We conduct a prospective multicentric study including, atypic-ductal hyperplasia (ADH), atypic-lobular hyperplasia (ALH), atypic-cylindro-cubic metaplasia (FEA), papilloma, radial scars (RS) and phyllod tumors. When several B3 lesions were associated, the more severe lesion was used to classify the lesion. We determined breast cancers (BC) rate and histologic type. Among 478 patients, 518 B3 lesions were studied: 15.1% (78) FEA, 48.6% (252) ADH, 16.8% (n = 87) ALH, 5.4% (n = 28) RS, 12% (n = 62) papilloma, 0.8% (n = 4) phyllod tumors and 0, 8% (n = 4) with a suspicious low grade DCIS. More than 1 lesion was identified in 31.9% (165) of cases. A surgical resection was performed for 86.3% (447/518) lesions. Significant factors of surgical resection were: residual micro-calcification after biopsy (OR: 2.7) and type of B3 lesion. Results: Overall BC rate was 15.3% (68/445) with 79.4% (54) in-situ carcinomas. According to B3 lesions, BC rates were 12.9% for FEA, 20% for ADH, 11.6% for ALH, 3.7% for RS, 8.8% for papilloma and 25% for suspicious in-situ carcinoma. A score has been calculated and patients were distributed in 3 groups. Patient's rates without BC were respectively: 100%, 80.4% and 80.6% (p = 0.029). Conclusion: In conclusion, it could be suggested to avoided complementary surgical resection in case of good radio-pathologic concordance and low probability of BC. Highlights: Among 518 B3 lesions a surgical resection was performed for 86.3%. BC rate was 15.3% (79.4% in-situ carcinomas): 20%–3.7% according toB3 lesion type. A score has been calculated with 3 groups. Surgical resection with low probability of BC.
