OBJECTIVES: Diagnosis of pancreatic lesions remains a clinical challenge. Early and accurate diagnosis is extremely important for improving the therapeutic usefulness of pancreatic cancers and Endoscopic ultrasonography - fine needle aspiration (EUS-FNA) cytology has come up with this advantage. For current study the authors evaluated the diagnostic accuracy of EUS-FNAC by applying PSC system for reporting pancreaticobiliary cytology and Calculated the malignancy risk associated with the diagnostic categories. MATERIAL AND METHODS: A retrospective study over the period of 2.5 years (April 2017 to Oct 2019) 60 patients in our cohort EUS-FNAC guided unstained fixed and unfixed slides received of pancreatic lesion and were stained with Papanicolau and Giemsa using standard technique and immunocytochemistry, where required Application of Papanicolaou Society of Cytopathology system for reporting pancreaticobiliary cytology Histopathological and clinical follow-up were retrieved. RESULTS: Our study has comparable results with sensitivity, specificity, PPV, and NPV of 92.8%, 100%, 100%, and 92.59%, respectively. Fuurthermore, a diagnostic accuracy of 96.2%. Risk of malignancy is lower for benign and indeterminate category whereas it is higher for suspicious and malignant categories. CONCLUSION: The application of the new proposed terminology for pancreaticobiliary cytology brings standardization. Final diagnosis can be reached by the multidisciplinary approach of EUS-FNA cytology, cell block preparation, immunocytochemistry, and immunohistochemistry; if required, can be adopted as an alternative approach to biopsy. The present study showed high sensitivity and specificity for EUS-FNA in the diagnosis of pancreatic carcinoma, which may influence the treatment plans of both surgeons and oncologists.
