Diagnostic value of breast mass biopsy in different locating methods / 中国医师进修杂志

ABSTRACT

Objective To explore the value of preoperative diagnosis for breast cancer patients in different locating ways. Methods The tissues were gotten by core needle biopsy from 146 breast cancer patients through different locating ways,and were taken for histopathological examinations and were compared with postoperative pathologic results. Results Seventy-four cases were biopsied with ultrasound-guide (ultrasound-guide group), and 72 cases with free-hand (free-hand group), without serious complications.Compared with postoperative pathologic results,the false negative rate in ultrasound-guide group was 5.41%(4/74);the false negative rate in free-hand group was 18.06% (13/72). The accuracy of the ultrasound-guided biopsy was higher than that in free-hand (U = 13.63,P ＜ 0.01 ). Conclusions Preoperative ultrasoundguided biopsy and postoperative pathologic examination has no significant difference, with high consistency.The study provides a good basis for selection for clinical work,so as to the more effective guide for the comprehensive treatment of breast cancer patients.
