Abstract:
Objective To analyze the incidence and mortality of cancer in Ya'an City in 2022 and its trends from 2013 to 2022.
Methods The crude and age-standardized cancer incidence and mortality rates (based on the Chinese standard population) were calculated by gender and age group from the Ya'an City registry data for 2022, and their trends from 2013 to 2022 were assessed using Joinpoint regression analysis.
Results In 2022, the crude incidence rate of cancer in Ya'an City was 317.19/105, and the age-standardized incidence rate was 178.45/105. The crude mortality rate of cancer in Ya'an City was 185.10/105, and the age-standardized mortality rate was 85.22/105. The top three cancer types with the highest incidence were lung cancer, colorectal cancer, and female breast cancer, and those with the highest mortality were lung cancer, colorectal cancer, and liver cancer. From 2013 to 2022, the overall age-standardized incidence rate of cancer was relatively stable but showed a downward trend in males (P<0.05) and an upward trend in females (P<0.05). The overall age-standardized mortality rate exhibited a downward trend (P<0.05). The age-standardized incidence rate of thyroid cancer, prostate cancer, and lung cancer showed an upward trend (P<0.05), whereas those of liver cancer, gastric cancer, and esophageal cancer showed a downward trend (P<0.05). The age-standardized mortality rate of gastric cancer, female breast cancer, liver cancer, and esophageal cancer showed a downward trend (P<0.05).
Conclusion The burden of cancer remains severe in Ya'an City. Targeted interventions should be implemented for lung cancer, colorectal cancer, female breast cancer, liver cancer, thyroid cancer, prostate cancer, and other common cancers to effectively control the cancer burden.
