Abstract :

Background: Fine Needle Aspiration Cytology (FNAC) is a well established technique in the biopsy of breast masses, although there has been a trend toward using Core Needle Biopsy (CNB). The aim of our study was to compare the effectiveness of both FNAC and CNB in identifying breast lesions. Methodology: A retrospective, comparative hospital based study conducted on 209 patients who underwent either FNAC and/or CNB breast lesions and had histopathological confirmation with surgical biopsy during the period from January 2010 to May 2015. Results: There were no false positives and only one false negative in CNB, while FNAC showed 3 false positives and 20 false negative results. The sensitivity, specificity, positive predictive value, negative predictive value and accuracy for FNAC were 79.4%, 96%, 96.3%, 79.6% and 87% respectively. CNB had 97% of sensitivity, 100% for both specificity and positive predictive value, 75% of negative predictive value and 97.6% of diagnostic accuracy. Conclusion: FNAC still regarded as the first method to evaluate less invasive breast lesions. CNB should be performed for equivocal diagnostic cases especially when evaluation of invasiveness or histological type of breast lesions is needed.
