Core Tip
Core tip: At initial biopsy, ‘indefinite for neoplasm/dysplasia’ (IFND) lesions proved to be adenocarcinomas (22.6%). Independent risk factors for gastric IFND cancer were age (≥ 60 years), endoscopic size (≥ 10 mm), single lesion, spontaneous bleeding, atypical epithelia, and repeated IFND diagnosis. Additionally, fold change predicted undifferentiated or invasive carcinoma in the submucosal layers or deeper. However, diagnostic delays shorter than 1 year were not associated with worse prognoses. In summary, for IFND lesions with these features, endoscopic resection may be a better option than repeated endoscopic biopsy. In the absence of associated risk factors, accurate diagnosis through follow-up within 1 year is recommended.
