THE IMPORTANCE OF VISUAL SCREENING FOR LUNG CANCER

Abstract

Relevance.Lung cancer is the leading cause of death among all cancers. An estimated 29% of the world's population 
over the age of 15 currently smoke tobacco. The presence of a high-risk population among tobacco smokers, the relatively 
asymptomatic nature of the disease at an early stage, and a relatively good prognosis with early detection make lung cancer 
screening attractive. This systematic review discusses recent advances in the use of imaging technologies in lung cancer 
screening, the rationale for screening, the results of ongoing research, and the current knowledge gaps in lung cancer 
screening. 
Aim. To review well-established imaging techniques, computed tomography and chest radiography, in lung cancer 
screening. 
Search strategy. The study examined full-text publications of foreign studies devoted to the methods of visual 
diagnostics, computed tomography and survey radiography of the lungs. The following search engines were used in the 
process of searching for literature: Pubmed, Web of science, Google Scholar by keywords. Publications with a depth of 20 
years were studied and analyzed, but some studies of authoritative authors of earlier years were included, which were of 
great value and without which it would be difficult to present the achievements in this area, the articles were mainly foreign 
and in English. More than 132 publications were identified on this topic. Of these, 67 publications met the objectives of our 
study. Inclusion criteria: Publications of evidence level A, B: meta-analyses, systematic reviews, cohort and cross-sectional 
studies. Exclusion criteria: brief reports, newspaper articles and personal communications. 
Results and conclusions. Comparison of plain chest radiography and computed tomography of the lungs in lung 
cancer screening. Advantages and disadvantages of imaging methods for lung cancer diagnosis are described. Cost
effectiveness of lung cancer screening using computed tomography and plain chest radiography is substantiated. 
Comparison of various aspects of chest radiography and computed tomography of the lungs in lung cancer screening based 
on the most advanced and emerging research.
