Comparison of the ultrasound-guided tru-cut biopsy with postoperative histopathology results in patients with breast mass.

AIM

We aimed to compare the tru-cut biopsy and postoperative pathology results of breast lesions with suspicion of malignancy. Furthermore we aimed to determine the efficacy, specificity and sensitivity of the tru-cut biopsy.

METHODOLOGY

140 patients who were operated due to breast mass following tru-cut biopsy were retrospectively evaluated. Patients' demographic characteristics, imaging findings, biopsy and histopathology results were compared.

RESULTS

The mean age of 140 patients was 51.3 (Ranged: 17-83 ages). Malignancy was statistically more common in patients older than 45 years old. According to tru-cut biopsy results 103 (73.5%) lesions were malign, 32 (23%) benign, and 5 (3,5%) suspicious. Histopathological evaluation established 113 (% 80.7) malign and 27 (19,3%) benign lesions. Tru-cut biopsy had a sensitivity, specifity, positive predictive value, negative predictive value and diagnostic accuracy of 93.5%, 95.4%, 99%, 75% and 80%, respectively in this study.

CONCLUSIONS

Our findings have confirmed that tru-cut biopsy is an accurate, reliable and as effective as open surgery for breast cancer diagnosis. The higher success rates may achieve by accordance of triple assessment which includes clinical, radiological and pathological evaluation with tru-cut biopsy.
