Abstract

Purpose: Intraductal papillary mucinous neoplasm (IPMN) has variable malignant potential ranging from premalignant intraductal lesions to malignant neoplasms with invasive carcinoma. To help physicians managing patients with IPMN, International consensus guidelines was made in 2006 and revised in 2012. This study was designed to evaluate the clinical usefulness of guidelines and to validate.
Methods: From October 1996 to December 2011, we retrospectively reviewed the data of 230 patients who underwent pancreatic resection for IPMN. Univariate and multivariable analyses were used to identify significant predictors of malignancy in IPMN.
Results: Of the 230 patients, 62 patients (27%) were diagnosed with invasive carcinoma. Jaundice (P < 0.001; 95% confidence interval [CI], 3.086?40.010) main pancreatic duct diameter equal to or greater than 10 mm (P < 0.001; 95% CI, 1.723?6.673) and also abdominal pain (P < 0.001; 95% CI, 4.363?22.600) show statistical significance in univariate and multivariate analysis. "High-risk stigmata" was statistical powerful predictors of malignancy than "worrisome features". International consensus guidelines 2012 had improvement on specificity but deterioration of sensitivity.
Conclusion: Revised guidelines seemed to bring about an improvement of weak side of Sendai criteria. Abdominal pain, jaundice, main pancreas duct greater than 10 mm can be clinical variables to predict malignancy.
