Pancreatic cancer (PC) is a fatal disease with a high mortality and poor prognosis. PC is the fourth leading cause of cancer death in America, and 80 % of PCs are diagnosed at an unresectable stage. Effective early detection assays are crucial since a successful operation at early stage is the best strategy for this disease. S100 calcium-binding protein P (S100P) has been reported as a predictive diagnostic index for PC and involves in the development of PC. However, the diagnostic accuracy of S100P in detecting PC has never been systematically assessed. The aim of the present study was to evaluate the diagnostic performance of S100P for PC. All relevant original articles about S100P in the diagnosis of PC published up to December 2013 were retrieved. The methodological quality of each study was assessed by QUADAS. The overall diagnostic sensitivity, specificity, diagnostic odds ratio (DOR), with 95 % confidence interval (CI), and area under the receiver operating characteristic curve (AUC) were pooled to evaluate the diagnostic value of S100P for PC using the Meta-DiSc1.4 statistical software. Eight studies met our criteria in the present meta-analysis. The pooled sensitivity, specificity, and DOR calculated by the bivariate random effects model were 0.87 (95 % CI 0.83-0.90), 0.88 (95 % CI 0.82-0.93), and 38.32 (95 % CI 11.22-130.87), respectively. The summary receiver operating characteristic (SROC) curve was located near the desirable left corner and the AUC was 0.9272. The current evidence suggests that S100P plays an important role in the diagnosis of PC with a high sensitivity and specificity. S100P may be regarded as a promising diagnostic marker to PC screening.
