Abstract
Data on polyps seen during colonoscopy that were identified using the JNET Classification and were biopsied were collected. 360 polyps identified using JNET Classification and sent for histopathology were included in the study. For JNET Type 1, the specificity, PPV and accuracy were 95.7%, 89.4% and 85.87% respectively. Sensitivity was low at only 66%. For JNET Type 2A, the sensitivity, PPV, and accuracy were 87.8%, 82.2% and 80.6% respectively. Specificity is 70% and NPV is 75.86%. For JNET Type 2B, the minimum sample size required for the study was not met. Nonetheless, specificity is 94% while NPV is 99.7%. Sensitivity and PPV cannot be determined because none of the biopsies were identified as a high grade intramucosal neoplasia or shallow submucosal invasive cancer. For JNET Type 3, specificity was 100% but sensitivity was low at 33%. PPV, NPV, and accuracy are at least 99%.
