A comparison of the long-term risk of malignancy between indeterminate cytological diagnoses, namely, atypical versus suspicious for malignancy, from endoscopic ultrasound-guided (EUS) fine-needle aspiration (FNA) of a pancreatic mass has not been well characterized. The primary aim of this study was to compare the risk of malignancy between patients with such indeterminate diagnoses. Secondarily, we investigated whether serologic markers serve as predictors of risk of malignancy in the setting of indeterminate cytological diagnoses.

We reviewed 484 cases of EUS-FNA on solid pancreatic lesions, performed at a single academic tertiary care center from 2004 to 2017. Patients with solid pancreas mass lesions who had atypical or suspicious final cytology were identified for further clinical outcome analysis.

Of the 484 patients with pancreas mass lesions, 53 (11 …
