Abstract

INTRODUCTION

In this study, we retrospectively reviewed the results and diagnostic value of the US guided coaxial breast TCB with current literature.

METHODS

A total of 343 patients were included in the study. The lesions were categorized as BI-RADS 3, BI-RADS 4 and BI-RADS 5 by using breast imaging reporting and data system (BI-RADS). Multiple biopsies were obtained from all lesions with coaxial fully automated TCB needle. Statistical analysis was performed with SPSS version 18.0.

RESULTS

After histopathological examination, 129 lesions were malign and 214 lesions were benign. The most frequent site of the masses was the upper external quadrant of the breast with 162 lesions. Retroareolar lesions were found to be benign in terms of statistical significance. Radiologically, 39.1% of the lesions were classified as BIRADS 3, 33.2% as BIRADS 4, and 27.7% as BIRADS 5. For BIRADS 3 lesions, the positive predictive value of ultrasonography for benign is 100%. The positive predictive value of ultrasonography for malignancy in BIRADS 4 lesions was calculated to be 29.8%. For BIRADS 5 lesions, the positive predictive value of ultrasonography for malignancy was evaluated as 100%.

DISCUSSION AND CONCLUSION

In our study, there was no non-diagnostic TCB. All of the 134 patients classifying BI RADS 3 were reported as benign. This finding encourages follow-up of BIRADS-3 lesions. Approximately 29,8% of BIRADS 4 lesions were diagnosed as malign in our study. However, most of these group lesions are benign lesions. This situation leads to the indication of TCB in BIRADS 4 lesions, while bringing in unnecessary biopsies. All 95 patients who were interpreted as BIRADS 5 were diagnosed as malignant. Therefore, BIRADS 5 lesions should be performed with biopsy. As a conclusion; Classification of breast lesions by US and ultrasonography guided coaxial TCB is an effective method which enables faster reliable preoperative planning without causing discomfort to the patient.
