ABSTRACT
OBJECTIVE:
To evaluate the clinical application of high-frequency ultrasound-guided vacuum-assisted biopsy for breast microcalcifications.METHODS:
Sixty-six patients with 70 lesions of microcalcifications detected at mammography underwent high-frequency ultrasound-guided vacuum-assisted biopsy from July 2009 to October 2010. All patients were female, aged 24 to 61 years (median age 40 years). Among 70 lesions of microcalcifications, unilateral lesions were 62 cases and bilateral lesions were 4 cases. The clinical factors that affected the success of biopsy were investigated by χ(2) test and Logistic regression analysis.RESULTS:
Among 70 lesions of microcalcifications, the successful rate of biopsy was 72.9% (51/70). The biopsy successful rate of microcalcifications without and with masses were 65.2% (30/46) and 87.5% (21/34) respectively (χ(2) = 3.960, P = 0.047). The biopsy successful rate of microcalcifications of maximal diameter more than 5 mm was higher than that of maximal diameter less than 5 mm (88.9% vs. 55.9%, χ(2) = 9.633, P = 0.002). The Logistic regression analysis showed that the types and maximal diameter of microcalcifications were the main factors that affected the success of biopsy.CONCLUSION:
The clinical application of high-frequency ultrasound-guided vacuum-assisted biopsy was an effective option for the diagnosis of breast microcalcifications, especially for the type of microcalcifications with masses and the maximal diameter more than 5 mm.
