Purpose: The purpose of this study was to compare the prevalence of carcinoma found at surgical excision identified as atypical ductal hyperplasia by the US-guided automated 14-gauge needle (AG) and the 11-gauge directional vacuum-assisted device (VA).
Materials and Methods: We retrospectively reviewed all sonographically guided core biopsies performed from January 2002 to June 2006. Evaluation of 3410 large-core needle biopsies (1093 VA and 2317 AG) yielding atypical ductal hyperplasia (61 lesions, 1.8%) was performed. The 19 cases that have not taken further surgical evaluation were excluded. The results of 41 large-core needle biopsies (17 VA and 24 AG) and subsequent surgical specimens were retrospectively compared between the two groups.
Results: The underestimation of breast carcinoma was significantly less frequent using the 11 gauge directional vacuum-assisted biopsy device than that with the automated 14-gauge needle (p =0.006). With the automated 14-gauge needle, 16(67%) of 24 lesions (8 ductal carcinoma in situ and 8 invasive ductal carcinoma) were underestimated. With the 11-gauge directional vacuum-assisted biopsy device, 4 (32%) of 17 lesions (2 ductal carcinoma in situ and 2 invasive ductal carcinoma) were underestimated. Atypical ductal hyperplasia underestimation rate of 11 gauge-VA is significantly lower than that of 14gauge-AG method in mass lesion or small lesion (less than 2cm). Lesion type, size and BI-RADS category did not affect ADH underestimation rate.
Conclusion: The frequency of histologic underestimation of breast carcinoma initially diagnosed as atypical ductal hyperplasia is significantly lower with the 11-gauge directional vacuum-assisted biopsy device (VA) than that with the automated 14-gauge needle (AG). Atypical ductal hyperplasia underestimation at US-guided core biopsy can be reduced but can not be removed by larger sampling amount.
