Incidence Trend of Lung Cancer in Iran: A Systematic Review and Meta-analysis

Abstract

Context: Lung cancer (LC) is one of the common diseases in the pulmonary system, which is defined as the uncontrolled growth of cells in the lung tissue. Objectives: The present investigation was conducted with the aim of the prevalence of LC in Iran by meta-analysis method. Methods: In this meta-analysis study, the articles that were conducted to determine age-standardized incidence rates (ASRs) in the field of LC were included in the study. The inclusion criteria included determining the number of ASRs in Iranian LC patients, reporting the sample size in men and women groups, and publishing articles between 2000 and January 2023. Data were analyzed, using CMA software. Results: In this meta-analysis study, 889 articles were found in the initial search, and after the final search, 23 articles were included in the meta-analysis stage. Out of the 22 final articles, the prevalence of LC was 3.7% (95% CI, 2.6 - 5.3) in women and 7.1% (95% CI, 5.7 - 9) in males. Conclusions: Considering that the incidence rate of LC in this study was high, it is essential to carry out necessary preventive interventions in this field.
