 ESD(endoscopic submucosal dissection)was performed in 593 patients(735 lesions)with early gastric cancer. Cases were divided into four groups, and the clinical course and prognosis after the procedure were retrospectively investigated. Group A comprised cases treated by curative resection ; group B, cases treated by noncurative resection, including those with positive or indeterminate margins and with surgical piece-meal resection because of technical reasons ; group C, cases with pathologically noncurative resection, and group D, cases with surgical resection. There was no lymph node or distant metastasis in any group during the follow-up period. In group D, residual cancer and lymph node metastasis were positive in three cases each(6.8%). The overall survival was no different among the groups. The disease-specific survival rate was 100% for groups B, C, and D. However, two patients died of metachronous gastric cancer in group A. No distant metastasis or death due to gastric cancer was noted during the follow-up period in patients treated by noncurative resection.
