Early detection of gastric cancer in Japan was discussed. The incidence of gastric cancer in Japan is high and has been increasing. The rates of increase in rural and urban areas have been similar. Until recently most diagnosed cases were advanced cancer that had a poor prognosis. Recently introduced techniques such as double contrast x-ray examination of the stomach and gastroendoscopy have improved the ability to detect cancer in its early stages. Clinical cases which were diagnosed and treated at the authors' hospital were discussed. A total of 127 patients with gastric cancer underwent surgery at the hospital between 1968 and 1977. Radical gastrectomy was performed in 94 cases. Only palliative procedures were done in the other cases because of the advanced stage of the cancer. Five of 14 cases in 1976 and 10 of 23 cases in 1977 were early gastric cancer. The 10 cases of early gastric cancer diagnosed in 1977 were summarized. Their age range was 27 to 72 years. Seven patients complained of slight epigastralgia. One complained of nausea. Two were asymptomatic and had been referred for detailed examination because of abnormalities found on routine stomach x-rays. Early gastric cancer was detected by double contrast x-ray examination in four cases and by gastroendoscopy in the other six. The authors conclude that a double contrast x-ray examination supplemented by an endoscopic examination should be performed on all patients with gastrointestinal distress. A follow up biopsy is recommended even if the lesion appears to be benign.
