Minute gastric cancer.

Nineteen cases of minute early gastric cancer were diagnosed under endoscopical examinations. Diagnosis was established by endoscopic biopsy in 18 cases, and exceptional one case of type IIb was incidentally found. Some of the endoscopic characteristic features of superficial depressed minute cancer were mentioned. By these findings, the diagnosis of superficial depressed minute cancer is possibly made in certain extent only by endoscopic observation. Prognosis of minute gastric cancer is excellent. Especially in the minute early cancer, the actual 7-year-survival rate was 100%. Prognosis of minute advanced cancer is also quite good. Minute gastric cancers can be found clinically and are almost completely curable.
