From 1963 to 1982, 756 cases of early gastric cancer were resected in our hospital. Of them, 717 cases (94.8%) were treated with limited operation without extended dissection of lymph nodes and omentobursectomy. These cases were followed up more than 10 years. A total of 202 patients died from the following diseases: recurrent gastric cancer (23 patients, 11.4%), cancer of other organs (42 patients, 20.8%) and non-cancerous diseases (137 patients, 67.8%). Concerning macroscopic types, were found a high recurrence rate (7.3%) and a low survival rate (88.1%) in the cases with mixed type. Cases with lymph node metastasis had a high likelihood of recurrence (18.8). The 10-year relative survival rate with lymph node metastasis was lower than without lymph node metastasis, 84.1% and 100.8% respectively. The recurrence rate with limited operation for early gastric cancer was 3.2%, and 2.9% for curative resection. The 10-year relative survival rate was 99.2%. We concluded that the limited operation should cure most cases of early gastric cancer and we should select the cases for extended dissection of lymph nodes.
