Abstract: Objective To investigate the ability of different standards on the evaluation of vascular invasion of pancreatic carcinoma. Methods The MSCT imagings of 56 cases of pancreatic carcinoma confirmed by surgery were analyzed retrospectively. The vascular invasion degrees of 5 large vessels around the pancreas were evaluated according to Loyer classification standard, Lu classification standard and the Changhai standard, the surgical result was used as the gold standard. The accuracy of different standards was evaluated, and the Kappa coefficient were calculated. Results The accuracy, sensitivity, specificity, positive predictive value and negative predictive value of Loyer classification standard were 86.79%, 86.27%, 86.90%, 59.46% and 96.60%, respectively, and the Kappa coefficient was 0.623. The accuracy, sensitivity, specificity, positive predictive value and negative predictive value of Lu classification standard were 93.21%, 84.31%, 95.20%, 79.63% and 96.46%, respectively, and the Kappa coefficient was 0.777. The accuracy, sensitivity, specificity, positive predictive value and negative predictive value of Changhai standard were 95.36%, 84.31%, 97.82%, 89.58% and 96.55%, respectively. The Kappa coefficient was 0.841. Conclusions The Changhai standard was feasible to evaluate the vascular invasion of pancreatic carcinoma.
