Long-term outcomes of endoscopic submucosal dissection and surgery for undifferentiated intramucosal gastric cancer regardless of size

Figure 1 Flow diagram of study population. ¹If the patient met within expanded indications except for lesion size factor > 2 cm (the only non-curative factor), we enrolled that patient for analysis. ASA: American Society of Anesthesiologists; EGC: Early gastric cancer; ESD: Endoscopic submucosal dissection.

Figure 2 Kaplan-Meier survival plots for recurrence-free survival and overall survival according to treatment modality for gastric cancer. A: Recurrence-free survival (RFS), endoscopic submucosal dissection (ESD) vs surgery; B: Overall survival (OS), ESD vs surgery; C: RFS, within the expanded indication vs beyond expanded indication; D: OS, within the expanded indication vs beyond expanded indication; E: RFS, ESD vs surgery in patients with beyond expanded indication; F: OS, ESD vs surgery in patients with beyond expanded indication. ESD: Endoscopic submucosal dissection.
