Ultrasound-guided vacuum-assisted core biopsy in the diagnosis and treatment of focal lesions of the breast – own experience

INTRODUCTION: Vacuum-assisted core biopsy (VACB) guided by ultrasound is a minimally invasive method used in diagnosis and treatment of breast focal lesions. Vacuum-assisted core biopsy is an interesting minimally invasive alternative to open surgical biopsy. AIM: To assess the value of ultrasound-guided vacuum-assisted core biopsy in the diagnosis and treatment of breast focal lesions. MATERIAL AND METHODS: In the period 2009-2010, 397 ultrasound-guided vacuum-assisted core biopsies were performed. Mean age of the patients was 41.7 years (18-92 years), and size of the lesions ranged from 3 mm to 65 mm, mean size being 12 mm. All women with diagnosed atypical ductal hyperplasia or cancer were qualified for surgery. The patients with histopathologically benign lesions were under follow-up. RESULTS: Samples sufficient for histopathological examination were obtained from 394 cases (99.2%). Of all 397 lesions, 293 (73.7%) were diagnosed as benign, there were 6 (1.6%) cases of atypical ductal hyperplasia and 98 (24.7%) malignant lesions. Three hundred and sixty-nine lesions were below 15 mm in diameter, of which 339 (91.9%) were totally removed during the VACB. CONCLUSIONS: The results obtained confirm high efficiency of ultrasound-guided VACB in the differential diagnosis of breast focal lesions, including impalpable ones. It is a safe method with a low complication rate. In the case of benign lesions with a diameter not exceeding 15 mm, it allows one to excise the whole lesion and is a very good alternative to an open surgical biopsy. Vacuum-assisted core biopsy should be a standard and the method of choice in diagnosing breast lesions.
