The prospective study of six cases of the aged patients with early gastric cancer revealed the following results, 1. Progression of type IIc early gastric cancer was slow. Especially, a case of small IIc type in early gastric cancer (Figure 5) was still observed IIc like lesion (Figure 6) on the 69 months after the first endoscopy. The doubling time in case No. l was 407 days (Figure 2, 3). 2. IIa type of early gastric cancer (Figure 8) had developed to Borrmann Type 2 of advanced gastric cancer (Figure 10) after three years to 4 years and 8 Months. Therefore, the growth rate of early stage of gastric cancer was slow but was rapid when it was advanced. 3. It was quite enough to do gastric mass survey in aged group within every two years by endoscopy.
