[A system of automated screening (used for factory personnel)]

The paper discusses automated screening procedures for detection of precancerous and tumor lesions in gastrointestinal organs in factory and office workers. These procedures include application of computers and a classifying matrix (a table of syndromes) in the processing of data obtained by means of questionnaires. Automated screening method provides a rationale for selection of subjects who should undergo further instrumental examination. Its application makes the work of medical staff at the initial stage of mass screening unnecessary. It also provides for standardization of procedures of screening for those who should be further examined for precancerous and tumor lesions in the esophagus, stomach, colon and rectum.
