- W1995031216 abstract "Abstract The measurement of fecal tumor M2‐pyruvate kinase (PKM2), overexpressed in tumor cells, has been proposed as a novel tool for detecting colorectal cancer (CRC). However, the sensitivity and specificity of this test varied among studies. The aim of this meta‐analysis was to determine the diagnostic accuracy of fecal PKM2 for CRC and to evaluate its utility in the CRC screening. It was compared to guaiac fecal occult blood test (gFOBT) or immunological fecal occult blood test (iFOBT). Through comprehensive literature search, 10 studies met the inclusion criteria and were included. Summary estimates for sensitivity and specificity were calculated by using the bivariate random effect model. The hierarchical summary receiver operating characteristic curve was also undertaken. The overall sensitivity and specificity of fecal PKM2 for detecting CRC were 79% (95% CI = 75–83%) and 81% (95% CI = 73–87%), respectively. The summary positive predictive value and negative predictive value were 74% (95% CI = 56–87%) and 86% (95% CI = 79–91%), respectively. The pooled diagnostic odds ratio was 16 (95% CI = 10–26). In head‐to‐head comparison, the diagnostic odds ratio of PKM2 and gFOBT for CRC were 10.167 (95% CI = 5.992–17.250) and 6.557 (95% CI = 3.467–12.403), respectively. The diagnostic odds ratio of PKM2 and iFOBT for CRC were 9.542 (95% CI = 5.893–15.452) and 67.248 (95% CI = 16.194–279.26), respectively. The fecal PKM2 test was a diagnostic tool with moderate sensitivity and specificity for detecting CRC. Its diagnostic efficiency was similar to that of gFOBT. Because of its relatively low specificity and positive predict value, fecal PKM2 was not recommended used alone as a screening tool for CRC." @default.
