Diagnostic accuracy of Modified Masood’s Scoring system for evaluation of breast lesions on Fine Needle Aspiration Cytology.

Introduction: FNAC has a pivotal role in the evaluation of breast lesions. Cytological grading systems are being utilized for the categorization of breast lesions. Modified Masood’s scoring System (MMSS) is used to improve the grading system for accurate pre-operative diagnosis. This study aims to assess the effectiveness and accuracy of the Modified Masood Scoring System for evaluating breast lesions and their correlation with histopathological diagnosis. Materials and Methods: This is a prospective study conducted in the Department of Pathology, MGM Medical College, Navi Mumbai which included 40 patients who presented with clinically palpable breast lump and were subjected to FNAC along with histopathological examination. The cytological smears were grouped into four categories according to MMSS. Correlation and concordance analysis between cytological categories and histopathological diagnosis was carried out. Observations and Results: The age of the patients ranged from 17 to 70 years with a mean age of 38.12 years, right-sided breast lesions were more common as compared to the left side. Of the total 40 cases, 27 cases were benign, and 13 cases were malignant on histopathology. The most common benign breast lesion was Fibroadenoma [Figure 1] and the malignant lesion was infiltrating duct carcinoma [Figure 2]. The sensitivity, specificity, Positive predictive value, Negative predictive value, and diagnostic accuracy were 76.9%, 100%, 100%, 90%, and 92.5% respectively. Conclusion: MMSS is simple, cost-effective, easily reproducible, reliable, and can be applied to FNAC aspirates to increase the diagnostic accuracy of Breast Lesions. [ABSTRACT FROM AUTHOR]
