抄録

During the past 10 years from 1988 to 1997, 68 lesions in 68 patients were treated by local resection for early gastric cancers at Akita Red Cross Hospital. The criteria for local resection were 1) intramucosal gastric carcinoma (m-carcinoma) within 30mm in size and having a clear tumor margin, and 2) submucosal gastric carcinoma (sm-carcinoma) within 20mm in size and having an intolerance for major surgery. Local resection was performed to all layer resection (AR) and submucosectomy (SM). Of 51 patients, 42 with m-carcinoma and 9 with sm-carcinoma were treated by AR. Forty-five of them were treated successfully by AR, and the rest underwent additional intervention. Of 17 patients, 14 with m-carcinoma and 3 with sm-carcinoma were treated successfully by SM. There were no recurrences of lymph node and distant metastases. The 5-year survival rate was 100% except for other causes of death, and no cancer deaths. These local resections of early gastric cancers were thought to be effective in improving the postoperative QOL of patients without loss of survival benefit.
