 We assessed the diagnostic performance of normal endoscopy for advance pSM invasive cancer with invasion depths of 1,000μm, 1,500μm, or 2,000μm using sensitivity, specificity, positive predictive value, and negative predictive value. The lesions examined included 103 of pM cancer, 306 of pSM cancer, and 403 of early colon cancer. Endoscopic findings were used to indicate any significant relationships of the invasion depth of pSM cancer with disease characteristics including (1) the presence or absence of perilesional extension failure, (2) the presence or absence of recessed deep, and (3) the presence or absence of a tense feeling. As a result, the most important findings were a tense feeling in the diagnosis with a sensitivity and specificity and recessed deep in the diagnosis with a specificity and a positive predictive value. Further, by the addition of 2 other diagnostic findings, it was possible to slightly improve the diagnostic accuracy. Satisfactory diagnostic results were achieved when focusing on A)sensitivity and specificity and B)the positive predictive value and specificity. It is accompanied with a problem proportion of cases to turn to the next inspection that becomes high. Further study is required to efficiently make a decision regarding appropriate therapy.
