Biopsija dojke pod kontrolom ultrazvuka - retrospektivna studija i pregled literature

AIM: The purpose of this study is to determine the accuracy and clinical usefulness of ultrasound guided core biopsy for diagnosing suspicious radiologically detected breast lesions. PATIENTS AND METHODS: We retrospectively evaluated the results of percutaneous core biopsy with 14-gauge needles performed over a period of 14 months on 229 suspicious lesions detectable on mammography and/or ultrasound exam (BI-RADS 4 or 5). The imaging-histological concordance was ascertained for each lesion. In cases of discordance, repeat biopsy or surgical excision was performed. Six-month ultrasound control was recommended in cases of benign lesions. For borderline and malignant lesions a surgical excision was done. Concordance between biopsy results and subsequent examinations (surgical excision or follow-up) was also evaluated. RESULTS: Histological analysis of core biopsy samples showed 143 (62.4%) benign lesions, 21 (9.2%) borderline lesions and 65 (28.4%) malignant lesions. Follow-up, repeated biopsy, or surgical excision showed four false negative cases. Accuracy of ultrasound guided core biopsy was 98.3%. CONCLUSION: Ultrasound guided core biopsy is a safe and reliable method for diagnosing suspicious breast lesions without any significant complications as was reported in previous studies.
