Abstract: | Background and objectiveEUS-FNA of pancreatic lesion has been put into clinical use widely in many centers. The present meta-analysis was conducted to study the diagnostic role of EUS-FNA in pancreatic cancer.MethodsA comprehensive review of study on the precision of EUS-FNA in the diagnosis of pancreatic cancer. A random effects model was used to pool the sensitivity, specificity, positive likelihood ratio (PLR), negative likelihood ratio (NLR) and diagnostic odds ratio (DOR). A summary receiver-operating characteristic (SROC) was constructed to summarize the overall test performance.ResultsThirty-one articles were eligible for the meta-analysis. The pooled sensitivity, specificity, PLR, NLR and DOR of EUS-FNA in the diagnosis of pancreatic cancer were 0.89 (95% CI: 0.88–0.90), 0.96 (95% CI: 0.95–0.97), 16.88 (95% CI: 10.63–26.79), 0.13 (95%CI: 0.10–0.16) and 150.80 (95%CI: 95.94–237.03) respectively. In subgroup meta-analysis of the prospective studies, the pooled sensitivity, specificity, PLR, NLR and DOR were 0.91 (95% CI: 0.90–0.93), 0.94 (95% CI: 0.91–0.96), 11.19 (95% CI: 6.36–19.69), 0.10 (95% CI: 0.07–0.15) and 125.22 (62.37–251.41). The area under the curve (AUC) was 0.97, indicating a good performance of overall accuracy.ConclusionEUS-FNA has the high sensitivity and specificity in differentiating pancreatic cancer. Moreover, it is also a safe diagnostic modality with little complications. |
