Correlation of preoperative citology/histology in radiologically detected lesions and histologic findings at excision

1552 Background: The major techniques used to diagnose breast abnormality has been for many years fine-needle aspiration (FNA) cytology and core needle biopsy (CNB) and more recently vacuum-assisted core biopsy (VACB). These techniques are accurate and allow definitive therapeutic surgery. The aim of our study was to detemine whether cytology/histologic findings mach histologic findings at excision. Methods: In our Institution, between January 2004 and June 2006, 43,138 mammographic exams were performed. 1,012 patients had patological lesions at mammography: 617 FNA cytology ( C due to European guidelines for breast cancer screening assessment) and 395 CNB/VACB (B) were performed. Patients with respectively suspicious and malignant FNA cytology (C4 and C5) and respectively uncertain malignant potential, suspicious and malignant histology (B3, B4 and B5) underwent to surgery. Results: The number of cancer identified by FNA cytology was 158 and the number of cancer identified by CNB/VACB was 253. The correl...
