Journal Title: Journal of Medical Science And clinical Research - Year 2018, Vol 6, Issue 7
Abstract
Background: Palpable breast lesions are one of the commonest presentations in general and oncological surgical practice. Breast cancer is the commonest cancer affecting women worldwide. Fine needle aspiration cytology (FNAC) is an ideal initial diagnostic modality in the management of palpable breast lesions which helps to avoid unnecessary surgical intervention in benign breast lesions and to confirm preoperative diagnosis in malignant breast lesions. Materials and Methods: Cytohistopathological correlation was done in 200 cases who presented with a palpable breast mass in FNA clinic of Dept. of Pathology, Government Medical College, Thrissur, Kerala. Results: A total of 200 cases was studied which included 87 benign cases (43.5%), 105 malignant cases (99 cases diagnosed as carcinoma and 6 cases as suspicious of malignancy) (Total 52.5%), 5 proliferative lesions with atypia (2.5%) and 3 inadequate cases (1.5%). Histopathological diagnosis of all 200 cases was collected and analyzed. There was a discrepancy in 5 cases (2.5%). Sensitivity, specificity, positive predictive value and negative predictive value of FNA for diagnosing benign lesions were found to be 98.8%, 96.3%, 95.6% and 99% and for malignant lesions the values were 96.3%, 98.8%, 99% and 95.6% respectively. The diagnostic accuracy of FNAC in this study was 97.45%. Conclusion: FNAC is a reliable primary screening technique for palpable breast lumps with high diagnostic accuracy and good specificity and positive predictive value, especially for malignant lesions.
