INTRODUCTION: The indications for resection of intraductal papillary mucinous neoplasms (IPMNs) have been optimized according to the high-risk stigmata (HRS) and worrisome features (WFs). However, the proportion of resected IPMNs diagnosed as low grade is not insignificant. This study aimed to investigate whether fibrinogen-to-albumin ratio (FAR) improves the diagnostic ability of high-grade dysplasia (HGD) or invasive carcinoma (IC) in IPMN.
METHODS: This study included 47 patients who underwent surgery between April 2008 and July 2024. Clinical factors were examined to determine HGD or IC. We also compared the accuracy of predicting HGD or IC between HRS alone and HRS plus FAR.
RESULTS: A total of 23 were diagnosed with HGD or IC based on pathological diagnosis. On multivariable analysis, contrasted walled nodules ≥5 mm and FAR ≥0.0833 were significant predictors of HGD or IC. Moreover, the HRS and high FAR (≥0.0833) group had better the positive predictive value and diagnostic accuracy rate.
CONCLUSIONS: FAR may be a significant predictor of HGD or IC in IPMN. In addition, when combined with HRS, its diagnostic ability as a predictor of HGD or IC may be further improved.
