This document from the American Society for Gastrointestinal Endoscopy (ASGE) provides a detailed description of the methodology used to evaluate the role of endoscopic submucosal dissection (ESD) in the management of early esophageal and gastric cancers. The guideline suggests that ESD is preferred over EMR and/or surgery in certain patient populations, based on tumor characteristics. Different recommendations are provided for different types of cancer and lesions, taking into consideration tumor size.
This document from the American Society for Gastrointestinal Endoscopy (ASGE) provides a full description of the methodology used in the review of the evidence used to inform the final guidance outlined in the accompa-nying Summary and Recommendations document regarding the role of endoscopic submucosal dissection (ESD) in the management of early esophageal and gastric cancers. This guideline used the Grading of Recommenda-tions, Assessment, Development and Evaluation framework and specifically addresses the role of ESD versus EMR and/or surgery, where applicable, for the management of early esophageal squamous cell carcinoma (ESCC), esophageal adenocarcinoma (EAC), and gastric adenocarcinoma (GAC) and their corresponding precur-sor lesions. For ESCC, the ASGE suggests ESD over EMR for patients with early-stage, well-differentiated, nonul-cerated cancer 15 mm, the ASGE suggests either ESD or EMR. The ASGE suggests against surgery for such patients with ESCC, whenever possible. For EAC, the ASGE suggests ESD over EMR for patients with early-stage, well-differentiated, nonulcerated cancer 20 mm, whereas in patients with similar lesions measuring <20 mm, the ASGE suggests either ESD or EMR. For GAC, the ASGE suggests ESD over EMR for patients with early-stage, well or moderately differentiated, nonulcerated intestinal type cancer measuring 20 to 30 mm, whereas for patients with similar lesions <20 mm, the ASGE suggests either ESD or EMR. The ASGE suggests against surgery for patients with such lesions measuring <30 mm, whereas for lesions that are poorly differentiated, regardless of size, the ASGE suggests surgical evaluation over endosic approaches.
