Abstract
We are presenting a detailed 10-year survival analysis by stage, age, calendar period of diagnosis, and type of treatment for patients with cancer of the stomach diagnosed in the State of Connecticut between 1935 and 1954. Observed survival is measured relative to expected survival in the general population. Among patients diagnosed 1935–44, about 1 out of 5 who were expected to survive the 1st year after diagnosis, in fact survived; of those expected to live from the end of the 1st year through the 5th year, 1 out of 3 survived. Mortality among the 5-year survivors was far greater than that of persons in the general population of similar age. Patients diagnosed 1945–54 experienced slightly higher 5-year survival than those diagnosed 1935–44; this improvement in length of survival was associated with an increase in the percent of patients treated by surgical intervention and an increase in the survival time of the surgically treated patients. The data suggest that the delay from onset of symptoms to treatment was not shortened, but that mortality from operations was reduced. Five-year survival rates for stomach cancer in Connecticut are similar to the average obtained at 8 treatment centers in the United States.
