[Determining the optimal frequency of preventive fluorographic examination of the population]. / Opredelenie optimal'noi periodichnosti profilakticheskikh fliuorograficheskikh obsledovanii naseleniia.

The results relating to a 4-year observation of 62,000 residents of Alma-Ata based on individual cards of fluorographic examinations are presented. It is shown that the intensive indices on the incidence of pulmonary tuberculosis, lung cancer and x-ray-positive nonspecific diseases of the lungs as well as the proportion of neglected forms of the diseases increased with increasing of the intervals between the fluorographic examinations. The economic losses due to the diseases also increased.

[The role of organization measures in the early detection of lung cancer during mass screening]. / Rol' organizatsionnykh meropriiatii dlia rannego vyiavleniia raka legkogo pri massovykh profilakticheskikh osmotrakh.

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.
