title: Evaluation of gastric mass survey.
abstract: The results of gastric mass survey during the 11-year period 1968-1978 were evaluated. The detection rate of gastric cancer was relatively high (0.22%) and that of early gastric cancer was surprisingly good (0.10%). The five-year survival rate (67%) accordingly was much higher than in Japanese out-patients in general. Gastric mass survey therefore is useful for the early diagnosis of gastric cancer. Although some questions of a practical nature remain to be solved, improvement and extension of surveys seem ot promise a reduction in the death rate from gastric cancer.
