[The clinical effect of recent decline in the gastric cancer mortality rate].
The clinical effect of the recent decline in the gastric cancer mortality rate in Niigata Prefecture was studied. The age-adjusted death rate for gastric cancer has been declining from average 60.5 per 1,000,000 population during 1958-1967 to 38.6 in 1981. From our analysis of surgically treated gastric cancer patients registered between 1972-1981 in Niigata Prefecture, the age-adjusted rate of early gastric cancer increased from 4.6 per 1,000,000 population in 1972 to 11.5 in 1981. Therefore, we conclude that there was a surgical effect of 46.1% in the decline in the gastric cancer mortality rate as of 1981.
