LUNG CANCER IN UKRAINE

Introduction. In 2022, 155,239 new cases of cancer and 84,153 deaths were registered in Ukraine. Among them, lung cancer was diagnosed in 18% of men and 1.4% of women. The study aimed to estimate the incidence of lung cancer in Ukraine and the Sumy region from 2014 to 2023 and to compare it with the indicators of the United States and China. Materials and methods. Data from the National Cancer Registry of Ukraine and the Global Cancer Observatory were used to investigate the incidence of lung cancer in Ukraine and worldwide. Statistical analysis was performed in the Stata V.18.0 software environment. Results. In Ukraine, men are 6.3 times more likely to have lung cancer than women. From 2014 to 2019, the incidence in men remained at a stable level. From 2020 to 2023, a rapid decline in morbidity is observed. Compared to 2019, in 2023, the number of incidents in men in Ukraine decreased by 1.5 times, and in the Sumy region, it decreased by 1.7 times. Lung cancer incidence rates among women in Ukraine from 2014 to 2019 were stable. In Sumy region, there was a trend towards an increase in morbidity. Thus, in 2014, compared to 2019, the number of registered cases increased by 41.2%. However, from 2020 to 2023, the morbidity began to decline sharply. Compared to 2019, in 2023, the incidence of lung cancer among women in Ukraine decreased by 1.4 times and in the Sumy region – by 1.9 times. At the time of diagnosis, 38.5±5.07% of patients in Ukraine and 24.2±2.92% in the Sumy region were diagnosed in advanced stages. The highest incidence without a tendency to decrease or increase is observed among Chinese men (an average of 49.2 per 100,000 population). The incidence is lower among men in the USA and Ukraine (an average of 38.2 and 33.7 per 100,000 population, respectively). Among Ukrainian women, the incidence is 5.7 times and 4.2 times lower than in the USA and China. Conclusions. During the period from 2014 to 2019 in Ukraine, the incidence of lung cancer among men and women was at a stable level. From 2020 to 2023, a decrease in morbidity is observed. In Ukraine and Sumy region, the proportion of newly diagnosed patients with stage IV has increased. Compared to the USA and China, the incidence of lung cancer among men and women in Ukraine is lower.
