2020-2024年重庆市潼南区恶性肿瘤发病和死亡趋势分析

Objective Based on the surveillance results of malignant tumors in Tongnan District, Chongqing City from 2020 to 2024, to analyze the trends of incidence and mortality, and to provide a scientific basis for the prevention and treatment of malignant tumors. Methods The surveillance data of malignant tumors in Tongnan District, Chongqing City from 2020 to 2024 were collected. The incidence rate, mortality rate, the top 5 ranking of incidence/death, gender and age groups were statistically analyzed. The characteristics and changing trends of incidence/death were summarized. Results The results showed that the crude incidence rate of malignant tumors in Tongnan District, Chongqing City, generally showed an increasing trend, and the crude incidence rate in men was higher than that in women. From 2020 to 2024, the statistics on the incidence of the top five tumors showed that the incidence and mortality rates among men were both higher than those among women. From 2020 to 2024, the overall incidence of malignant tumors increased with age, with the high-incidence age group being ≥70 years old. The top five anatomical sites of new malignant tumors in men, from high to low, are(trachea, bronchi, and lung), liver, esophagus, colorectal and anal, and stomach. The top five anatomical sites of new malignant tumors in women, from high to low, are(trachea, bronchi, lung), breast, colorectal and anal, liver. The order of crude mortality rates for men is(trachea, bronchi, lung), liver, esophagus, stomach, colorectal and anal. For women, the sequence is(trachea, bronchi, lung), liver, esophagus, colon, rectum and anus, stomach, pancreas, and breast. Conclusion The incidence and mortality rates of malignant tumors in Tongnan District were higher than the national average. From 2020 to 2024, both the incidence and mortality rates of malignant tumors in Tongnan District, Chongqing City, are on the rise. The high-risk groups are men and the elderly. There are gender differences in the tumor sites. Special attention should be paid to key cancers such as lung cancer, liver cancer, colorectal cancer, esophageal cancer, and gastric cancer. We should do a good job in comprehensive prevention and control work such as health education, screening and intervention, and early diagnosis and treatment to reduce the incidence and mortality of malignant tumors.
