To the Editor We read with great interest the article by Chen et al1 reporting a prediction model based on collagen architecture and morphology to estimate the risk of lymph node metastasis (LNM) in patients with early gastric cancer (EGC). The newly developed tools were suggested to be useful in decision-making in the choice of surgical or endoscopic submucosal dissection (ESD) treatment in patients with T1 gastric cancer. However, we have some concerns about this study from the perspective of endoscopists.
