[The role of organization measures in the early detection of lung cancer during mass screening].

The experience gained in fluorographic mass screenings for early detection of lung cancer in Rostov Region showed their effectiveness to depend on differential selection of population study groups on the basis of examination periods determined according to the data of local registries, formation of high risk groups on the basis of the suggested criteria, and further research in the rhythm of fluorographic screenings in different population groups. Practical aspects of mass screenings deserve more attention. The percentage of lung malignancies detected in the course of mass screenings increased as a result of taking certain effective organizational measures, thus making the case for further research into the problem.
