Background.
More clinically meaningful diagnostic tests are needed in pancreatic cancer (PC).
K-ras mutations are the most frequently acquired genetic alteration.
Methods.
Original research articles involving the diagnostic accuracy of K-ras mutation detection in PC were selected.
Data were presented as forest plots and summary receiver operating characteristic (SROC) curve analysis was used to summarize the overall test performance.
Results.
We assessed 19 studies from 16 published articles.
The reports were divided into three groups according to the process used to obtain the test material.
The summary estimates for detecting K-ras status using an invasive method (fine needle aspiration (FNA), endoscopic retrograde cholangiopancreatography (ERCP), or surgery) were better than cytology: the pooled sensitivity was 77% (95% confidence interval (CI): 74–80%) versus 54% (95% CI: 47–61%); specificity was 88% (95% CI: 85–91%) versus 91% (95% CI: 83–96%); and diagnostic odds ratio (DOR) was 20.26 (11.40–36.03) versus 7.52 (95% CI: 2.80–20.18), respectively.
When two procedures were combined, the diagnostic accuracy was markedly improved.
Conclusions.
The analysis of K-ras mutations in pancreatic tissue has a promising diagnostic significance in PC.
Further valuable studies are needed.
