ABSTRACT
The specificity and reliability from fine needle aspiration (FNA) and tru-cut biopsy as a diagnostic tool of breast cancer is actually a subject of discussion. Both procedures are used as screening test in the handling of suspicious lesions of breast cancer. The objective of the present study was to assess the sensibility, specificity, predictive positive value (PPV), predictive negative value (PNV) and diagnostic accuracy from both procedures, comparing their results with breast cancer diagnosis. The sample was obtained from histologic reports of the patients who went under either, FAN, tru-cut biopsy. “Gold standard” for both tests was the histologic report of the biopsy excisional or the of mastectomy piece. The sample was constituted by 132 cases. The results of the FAN were: sensibility of 88%, specificity of 98%, PPV of 98%, PNV of 87% and diagnostic accuracy of 92%. Tru-cut biopsy results were: sensibility of 88%, specificity of 100%, PPV of 100%, PNV of 85% and diagnostic accuracy of 93%. The inadequate samples of both procedures were 13 (9.8%) and 19 (14.32%) for BAAF and tru-cut biopsy, respectively. The evaluation of both results with the χ2 test showed that there is no significant difference between both procedures.
