[Malignant neoplasms of the stomach in Berlin, capital of the G.D.R. - An analysis of the state of diagnosis and treatment].

In Berlin, capital of the German Democratic Republic, 7,386 new cases of gastric cancer (ICD 151) were registered in the period from 1955 to 1969 and in year 1973. 52 percent of patients were male. Percentage of cases 75 years old and more, increased from 21% (1955-1959) to 36% (1965-1969). There were only slight changes in incidence. About 30% of cases were in the operable stages I and II. With rising age, the proportion of the advanced stages III and IV increases. No real progress as made in early diagnosis of stomach cancer as measured by stage distribution during observation period. Patient's delay from first symptom to first visit was shorter than one month in 40%, physician's delay from first visit to correct diagnosis was shorter than one month in 54%. 15% of patients were treated within one month after first symptom and 47% within three months. There was no correlation between duration of history and percentage of early stages. When observation periods 1955 to 1959, 1960-1964, 1965-1969 and 1973 are compared, we find an increase in old patients (75+ years), a decrease of localized stages I + II, and a decrease in resection rate. Therefore, a decrease in survival rates is to be expected. Crude 5-year survival rate was 6.4% (1955-1959) and 6.2% (1960-1964). When we compare data from Berlin with observations in the Region of Erfurt and in Birmingham Region, the situation of detection and treatment of stomach cancer in Berlin seems to be somewhat better. Finally, some suggestions for the improvement of control of stomach cancer are made.
