To evaluate the accuracy of our newly developed scoring systems in predicting early recurrence, we determined the ROC curves of our preoperative and postoperative scoring systems, as well as the currently used tumor markers (CA19-9, CEA, CA242), and the five independent inflammatory markers (neutrophils, platelets, lymphocytes, monocytes and ALB) or even their combinations (NLR, PLR, LMR, PNI, NAR and PAR) during the preoperative and postoperative period in the training group, and then compared their performance in predicting early recurrence of PDAC patients (Table 3). Here, ALB is linked to neoplasm.
