In 1941, Walters, Gray, and Priestley1 with the assistance of Berkson described the results of an intensive study of cases of cancer of the stomach encountered at the Mayo Clinic in the 32 years from 1907 through 1938. In that study of approximately 11,000 patients, 6,352 underwent operations and 2,840 had gastric resections. This gave a resectability rate of 44.7%. When the 1907-1938 series is contrasted with the 1956-1957 series, an increase in resectability from 44.7% in the early period to approximately 60% in 1956 and 1957 is evident.
Comparison of Results over the Years
In the interval between these two periods several studies have been made on the treatment of cancer of the stomach at the Mayo Clinic, and I should briefly like to refer to those made in the period 1940 through 1949 and to contrast some of the observations with those of recent, partially completed studies
