However, it is not clear whether EU can differentiate exactly between mucosal gastric cancer and deeper gastric cancer. In different studies, the sensitivity of measurement of this difference varies from 18.2% to 100% average 87.8%, specificity varies from 34.7% to 100% average 80.2%, and accuracy is 89.24% as measured by areas under ROC curves 7.
