Cancer Incidence Trend in Chinese Longevity Town Cenxi City from 2016 to 2020
Abstract
Background Along with the acceleration of population aging and the increase in average life expectancy, how to improve the quality of life of residents has become a social focus. Cancer is a major factor that seriously affects the health, causing increased medical burden. Therefore, it is of great significance to analyze cancer incidence in Cenxi City, Guangxi. Objective To perform a statistical analysis of cancer incidence in Cenxi from 2016 to 2020. Methods Data on cancer incidence in Cenxi from 2016 to 2020 were obtained from the Cancer Registry System of Cenxi Center for Disease Control and Prevention. Cancers were classified by the Guideline for Chinese Cancer Registration and International Classification of Disease for Oncology, Third Edition (ICD-O). Sex-specific and age-specific crude incidence rates, standardized incidence rates, and cumulative incidence rates (0-74 years), as well as truncated age-standardized incidence rate (35-64 years) were calculated. The standardized incidence rate was calculated by the 2000 Population Census of China and Segi's world population structure (Chinese age-standardized incidence rate was referred to as ASIRC, and world age-standardized incidence rate as ASIRW) . Results There were 4 205 registered new cases of cancer from 2016 to 2020 in Cenxi. The crude cancer incidence rate was 98.77/105. The ASIRC, ASIRW, cumulative incidence rate (0-74 years) and the truncated age-standardized incidence rate (35-64 years) were 85.48/105, 82.54/105, 9.08%, and 165.08/105, respectively. The male crude incidence rate was higher than that in female (χ2=161.703, P<0.001). The crude cancer incidence rates for 0-34 year-old overall population, males and females were all under 34.00/105, for 35-39 year-old overall population, males and females were 64.02/105, 83.94/105, 43.75/105, respectively, and for 75-79 year-old were 437.83/105, 597.17/105, 292.76/105, respectively, reaching the highest incidence rate. The top three cancers in terms of crude incidence rate for the overall population were liver cancer (23.47%), lung cancer (17.53%), and nasopharynx cancer (10.70%), for males were liver cancer (30.94%), lung cancer (20.84%), and nasopharynx cancer (12.51%), while for females were breast cancer (16.44%), lung cancer (12.12%), and liver cancer (11.31%) . Conclusion Compared to the Chinese average (ASIRC and ASIRW were 190.64/105, 204.8/105), and world average (ASIRW were 201.0/105) from 2016 to 2020, Cenxi had lower overall standardized cancer incidence rates (ASIRC and ASIRW were 85.48/105, 82.54/105). The crude cancer incidence rate in males was higher than that of females. The crude cancer incidence rate reached its peak at the age range of 75-79 years for the overall population, males or females. The top three cancers in terms of crude incidence in the overall population were liver cancer, lung cancer and nasopharynx cancer.
