ABSTRACT
Objective@#To explore preoperative predictive markers for invasive malignancy in intraductal papillary mucinous neoplasm(IPMN).@*Methods@#The retrospective case-controlled study was adopted.Seventy-nine patients who underwent surgery and with pathologically confirmed IPMN from January 2005 to December 2014 at Department of Pancreatic Surgery, Zhongshan Hospital Fudan University were enrolled.Forty-six patients were male and 33 were female,with an average age of (62.9±8.9)years (range37-82 years).Tumor sites56 tumors were located at the head of the pancreas,22 were located at the body and tail of the pancreas,and 1 was located across the whole pancreas.Surgical procedures 51 patients underwent pancreaticoduodenectomy, 22 patients underwent distal pancreatectomy, 4 patients underwent segmental pancreatectomy and 2 patients underwent total pancreatectomy.IPMNs were classified into non-invasive lesions and invasive carcinomas according to the histopathological findings of the tumor.Thirty-two tumors were non-invasive lesions and 47 were invasive carcinomas.The preoperative findings were compared between patients with non-invasive IPMN and patients with invasive carcinoma by univariate analysis using t test and χ2 test accordingly,and factors with statistically significance were subsequently submitted to multivariate analysis.@*Results@#Univariate analysis showed that tumor size(P=0.022), carcinoembryonic antigen(P=0.012), CA19-9(P=0.011), lymphocytes(P=0.034), neutrophil-to-lymphocyte ratio(P=0.010)and platelet-to-lymphocyte ratio(PLR)(P=0.004)were predictive markers with statistical significance.Multivariate analysis showed that CA19-9(P=0.012)and PLR(P=0.025) were independent predictive markers for invasive malignancy in IPMN.The area under curve of the combination factor of CA19-9 and PLR(0.864) was larger than that of CA19-9(0.806) or PLR(0.685) alone, and all the authentic indicators of the combination factor were better than those of each alone.@*Conclusions@#CA19-9 and PLR are independent predictive markers for invasive malignancy in IPMN.The combination of CA19-9 and PLR has improved efficacy than each alone.
