✦ Synopsis

with IRFE. However, the specificity was simultaneously decreased to 87%, suggesting that neovascularization can occur even with submucosal invasion up to 500 micrometers.

Generally, ulcerative lesions have many vessels during the healing process, and it would be expected that fluorescence positivity in gastric cancer of the ulcerative form is affected by the vessels, independent of tumor vascularization. False-positive results should be evaluated in a larger number of cases of intramucosal cancer accompanied by ulceration; however, we had only 1 case in this study. In our preliminary study using IRFE, benign gastric ulcers showed no distinct fluorescence, unlike gastric cancer with submucosal invasion, and we hypothesize that there are differences in vessel walls and the mechanism of dye pooling into interstitial spaces. 2 The accuracy rate of IRFE for determining depth of invasion in the cases with ulceration was 83%, which seems to be equivalent to or as effective as EUS.
