  • Abstract
  • Look Inside

 During the term from May 1962 to December 1976, 732 cases of early gastric cancer with single lesion were operated on at the National Cancer Center Hospital. In these cases, survival rate of each year was calculated with the Life Table Method (by Sidney J. Cutler et al.) with regard to several factors affecting prognosis of early gastric cancer, such as the depth of cancer invasion, lymph node metastasis, the depth of the gastric ulcer or ulcer scar accompanied with early gastric cancer (by Murakami's classification), macroscopic classification and histological type, etc.

Results :

 1) Five-year survival rate of all early gastric cancer cases was 97.7% and 10-year survival rate was 96.4%.

There was no recurrent cancer case after 10 years. So that, the prognosis of early gastric cancer should be estimated at the period of 10 years after the initial surgical treatment.

 2) Significant difference was found between cases with lymph node metastasis and without.

 3) Early gastric cancer cases associated with deep gastric ulcer or ulcer scar in the cancerous lesion showed a little worse prognosis than the cases with shallower ulcer or its scar.

 4) Early gastric cancer cases of protruded type presented an earlier recurrence than those of depressed type. And liver metastasis was the main cause of ealry recurrence of these cases with protruded type cancer.

 5) Almost all of these cases with earier recurrence showed well-differentiated adenocarcinoma histologically. The other cases with histological type of poorly differentiated adenocarcinoma showed a relatively late recurrence.
