title: [Malignant tumors of the gastrointestinal tract and their early diagnosis].
abstract: Malignant tumors of the gastrointestinal tract belong to the main causes of death. The overall 5-years-survival rate is low. Systematic investigations of early gastric cancer and polyps of the colon revealed that asymptomatic carcinomas are detectable and have a definite chance for curative treatment. Mass survey of the population by means of endoscopic or radiological procedures are impossible due to high financial expense. Therefore, other diagnostic tools have to be inaugurated. Besides a maximum diagnostic effort in each individual with gastrointestinal complaints, high risk groups with a significantly increased incidence rate of malignant tumor development have been established. Thorough observation of those persons is necessary as are simple, inexpensive and practicable methods for screening examinations.
