摘要: Abstract Purpose Pancreatic neuroendocrine tumors (PNETs) exhibit various tumor behaviors and symptoms that are difficult for physicians to stage predict prognosis. We assess prognostic factors combined with staging classifications optimal the models try improve follow-up strategy monitor liver metastases after surgery. Methods Patients PNETs treated at Sun Yat-sen Memorial Hospital between 2000 2015 were recruited. regrouped on basis of functional status mitotic rates. Nomograms values (AJCC, ENETS, WHO) constructed; accuracy nomograms quantified by C-index calibration plots. Results identified 78 patients pathological reports. Correlations OS in univariate analysis included nonfunctional ( P = 0.002), CgA>200 ng/ml = 0.014; >20%, = 0.011; >20/10HPF, = 0.039; 3–20/10HPF, = 0.015; = 0.007). Evaluating new proposed system, difference low- high-groups was statistically significant = 0.001). The higher than premise ones (AJCC cohort, 0.605 v 0.576, 0.691, 0.603, Conclusion An model based rates correlates strongly survival. should return visits every 2 months first half years, 3 as followed until years
