Clinical management of gastric indefinite neoplasia (category 2 lesion) from endoscopic forceps biopsy is difficult to decide management in some conditions such as suspicious of early gastric cancer (EGC), macroscopically.


This retrospective study enrolled 127 patients of gastric indefinite neoplasia on index forceps biopsy. We analyzed the initial endoscopic distinctive features of lesions and predictive factors of EGC.


After complete work-up, the ultimate pathologic diagnoses were early gastric cancer (n =28, 22.0%), adenoma (n =9, 7.0%), and non-neoplasm (n =90, 70.8%). In the univariate analysis, lesion size more than 10 mm, surface nodularity and surface redness were associated risk factors. In the multivariate analysis, lesions diameter (p =0.023, OR 11.409, 95% CI 1.441-90.762) and surface redness (p =0.012, OR 3.762, 95% CI 1.312-10938) were significant risk factors.


Gastric indefinite neoplasia with larger size (≥ 10mm) and surface redness might be require more definite diagnostic modalities rather than simple and serial follow up endoscopy.
