The detection rates for malignant gastric tumors, particularly gastric cancers,were investigated in 5,975 first-time visits and 5,027 total revisits at the Nagano Cancer Center over the last 20 years. The detection rate for gastric cancers among first-time visits was 2.8% and among those reexamined 0.8%. In terms of the reason for the total visits,those in the referral group (6.4%)were the highest,followed by the voluntary visit group (1.9%), the mass screening group (1.5%), and other physical check-up group (1.1%). The proportion of gastric cancers was shown to rise with increasing age. In terms of the presence or absence of subjective symptoms among first-timers, the detection rate of gastric cancers in the group with subjective symptoms was higher than in that without subjective symptoms. In terms of the presence or absence of a hereditary relationship with gastric cancer among first timers, the detection rate of gastric cancers in the group with this factor was higher than in that without it. The Proportion of early cancers among detected gastric cancers accounted for over half,and those in the more recent decade were significantly higher than those in the earlier one. In summary,it was considered that sufficiently accurate examinations carried out for cancer screening in the upper gastrointestinal tract at Nagano Cancer Center.
