Abstract
- The reported outcomes of endoscopic resection (ER) for early gastric cancer (EGC) remain limited to several single-institution studies. A multicenter retrospective study was conducted at 11 Japanese institutions concerning their results for ER, including conventional endoscopic mucosal resection (EMR) and endoscopic submucosal dissection (ESD). A total of 714 EGCs (EMR, 411; ESD, 303) in 655 consecutive patients were treated from January to December 2001. Technically, 511 of the 714 (71.6%) lesions were resected in one piece. The rate of one-piece resection with ESD (92.7%; 281/303) was significantly higher compared with that for EMR (56.0%; 230/411). Histologically, curative resection was found in 474 (66.3%) lesions. The rate of curative resection with ESD (73.6%; 223/303) was significantly higher compared with that for EMR (61.1%; 251/411). Blood transfusion because of bleeding was required in only 1 patient (0.1%) with EMR of 714 lesions. Perforation was found in 16 (2.2%). The incidence of perforation with ESD (3.6%; 11/303) was significantly higher than that with EMR (1.2%; 5/411). All complications were managed endoscopically, and there was no procedure-related mortality. The median follow-up period was 3.2 years (range, 0.5–5.0 years). In total, the 3-year cumulative residual-free/recurrence-free rate and the 3-year overall survival rate were 94.4% and 99.2%, respectively. The 3-year cumulative residual-free/recurrence-free rate in the ESD group (97.6%) was significantly higher than that in the EMR group (92.5%). ER leads to an excellent 3-year survival in clinical practice and could be a possible standard treatment for EGC. ESD has the advantage of achieving one-piece resection and reducing local residual or recurrent tumor. [ABSTRACT FROM AUTHOR]
