 We investigated the problems of multiple early gastric cancers for endoscopic treatment. The incidence of simultaneous multiple early gastric cancers in the resected stomach was 9.4%. In elderly patients, however, the incidence was higher than that of all ages: aged 70-79 years; 13.7% and aged over 80 years; 17.6%. Histological examination of the resected specimen revealed that 79.3% of multiple early gastric cancers was a combination of differentiated adenocarcinomas.

 Endoscopic treatment includes laser irradiation treatment and endoscopic mucosal resection.“simultaneously discovered carcinoma”was found in 10.5% of the cases with laser treatment, whereas“carcinoma discovered during the follow-up period”was 8.8%. Endoscopic mucosal resection was performed in 65 lesions of 58 cases (mean age; 68.9 years).“simultaneously discovered carcinoma”was found in 6.9% of these cases and“carcinoma discovered during the follow-up period”was found in 5.2%.

 Since all carcinomatous lesions that were discovered in other areas of the stomach during the follow-up period could be treated endoscopically, current observation method seems to be adequate.

 Furthermore, there is a high probability of discovering new lesions in multiple cancer cases, therefore it is important to perform endoscopic observation with great care.
