Abstract
BACKGROUND: Fine-needle aspiration cytology plays role in preoperative diagnosis of any salivary gland mass lesions. Because of heterogeneity of salivary gland lesions and cytomorphology overlap, a uniform 6-tier Milan classification proposed which could be helpful in better communication of reports for patient's management. METHODS: Study included 4 years (2011-2015) retrospective data retrieval from cytology department of our Institute, which is a tertiary care cancer center of South India. Histopathology correlation was done wherever possible. RESULT: Total 253 cases were studied. Histopathological follow-up was available in 115 cases. Cases were categorized as nondiagnostic (1.58%), nonneoplastic (13.43%), benign (30%), atypia (0.8%), and suspicious for malignancy and malignant cytology (51.8%). The risk for malignancy was high for suspicious for malignancy and malignant cytological categories ranged from 96-100%. The sensitivity, specificity, and accuracy for diagnosing malignancy varied from 86.76%, 93.75%, and 89%, respectively. CONCLUSION: Risk stratification approach in classifying salivary gland cytology aspirate as per Milan system provides a standardized reporting and better communication to clinician.
