 Based on the current guidelines, ESD(endoscopic submucosal dissection)is accepted as a standard treatment only for EGCs(early gastric cancers)with a very low risk of lymph node metastasis(<1%). The standard treatment for other EGCs is surgical gastrectomy with lymphadenectomy regardless of patient age. However, gastrectomy for elderly patients is associated with a higher risk of complications and poor quality of life. Even when the procedure is successful, elderly patients may die of other diseases soon after treatment. In order to avoid overtreatment with gastrectomy, we proposed new ESD indications for elderly patients and initiated a clinical trial(JCOG1902)to confirm the non-inferiority of treatment with initial ESD for elderly patients with EGCs meeting the new indications versus standard gastrectomy. If non-inferiority is proven, ESD will be considered an appropriate initial treatment option for qualifying elderly patients.
