uPAR, urokinase plasminogen activator receptor; H, head of pancreas; B, body of pancreas; T, tail of pancreas; P, papillary adenocarcinoma; Muc, mucinous carcinoma; W, well-differentiated adenocarcinoma; Mod, moderatery-differentiated adenocarcinoma. The pT, pN, and pM categories were determined according to the TNM classification [19]. The ap-values were obtained using the Mann-Whiteny U test. Values of age are given mean ± s.d. N.S., no significant.
