The purpose of this study is to establish a scoring system for preoperative screening of resectable patients. Methods: The clinical information and laboratory tests of 105 resectable patients with PC were enrolled and analysed. Results: The consistency of clinical stage and pathological stage was poor (κ = 0.193, P
