Open surgical biopsy for nonpalpable breast lesions detected on screening mammography.
The aim of this retrospective clinical study was the analysis of histologic findings of nonpalpable breast lesions managed by open surgical biopsy. A series of 630 women underwent 664 preoperative localizations of nonpalpable, mammographically detected breast lesions during the last 10-year period. Indications for biopsy were (1) clustered microcalcifications, (2) solid mass, and (3) radiologic parenchymal distortion. The lesions were localized preoperatively using hook-wire methods, and all biopsies were performed under general anesthesia. Histopathology revealed carcinoma in 172 (25.9%) cases; noninvasive in 114 (66.3%) cases and infiltrating in 58 (33.7%) cases. The highest malignancy rate was found in cases with microcalcifications (112 carcinomas out of 323 cases, 34.7%). Lymph node invasion was present in 25% of patients with invasive cancers. The hook-wire localization of nonpalpable breast lesions is a simple, accurate and safe method for detection of early breast cancers. Frozen section is feasible and accurate in the majority of these lesions, and therefore, diagnostic and therapeutic one-step surgical procedures could be performed.
