 Among 1,011 cases of gastric cancer detected by our association's gastric mass examination out of 717,199 examinees during the period between 1992 and 1994,202 cases of advanced cancer who had previously undergone screening examinations were evaluated for the development and progress of cancer by reassessment of the previous 478 x-ray films for six years prior to detection. For the evaluation purposes, the detected cancers was classified into six types (Type Ⅰ to Ⅵ) by the presence of peptic ulcers and carcinomatous protrusions.

 By the analysis of the annual lesion appearance rates, rates were low for the cancers of Ul(-) group, such as the Types ⅠA, ⅡA and ⅢA, which indicated that the cancer without peptic ulcers may showed rapid morphological changes. On the other hand, the annual lesion appearance rates were high for cancers of Ul(+) groups, such as the Type ⅤA and ⅥA, which suggested that the cancer with peptic ulcers may progress slowly. Our study estimated the relation between previous and current shapes of the advanced gastric cancer as follows: Type ⅠA may develop from Type ⅠE, Type ⅡA from Types ⅡE and ⅢE, Type ⅢA from Type ⅢE, Type ⅤA from Types ⅤE and ⅥE, and Type ⅥA from Type ⅥE.
