To analyze the epidemiological characteristics of malignancy deaths and the changing patterns of potential life loss in Hengshui City from 2015 to 2024, providing data support for the formulation of malignancy prevention and control strategies.
We collected data on malignancy deaths among registered residents in Hengshui City, calculated the standardized mortality rates for total, gender, age, and malignancy categories, and analyzed the potential life loss and trends for the top four leading causes of malignancy deaths.
The standardized mortality rates for malignancy among registered residents in Hengshui City from 2015 to 2024 were 81.05/100 000, 72.89/100 000, 92.47/100 000, 97.23/100 000, 105.47/100 000, 97.66/100 000, 115.93/100 000, 116.78/100 000, 125.23/100 000, and 125.87/100 000, showing an upward trend (AAPC=6.20%, P<0.05). The standardized mortality rates for males were higher than those for females (all P<0.05). The top four leading causes of malignancy deaths among registered residents in Hengshui City were lung cancer, stomach cancer, liver cancer, and colorectal cancer, accounting for 26.51%, 11.34%, 11.57%, and 4.64% of deaths, respectively. The standardized mortality rates for all four malignancies showed an upward trend, with AAPC values of 11.01%, 15.17%, 3.35%, and 9.43%, respectively (all P<0.05). The proportions of malignancies, lung cancer, liver cancer, and stomach cancer in the 70-79 age group showed a significant upward trend for both males and females, and the proportion was the highest. The average age at death from malignancies, lung cancer, liver cancer, and stomach cancer showed a slight upward trend (AAPC: 0.46%, 0.47%, 0.54%, 0.46%, respectively; P<0.05), while the trend in the average age at death from colorectal cancer was not significant. Among the top four leading causes of malignancy deaths, lung cancer had the highest mean potential life loss (PYLL: 12 123.00 person-years), liver cancer had the highest average potential life loss (AYLL: 15.97 years), and lung cancer had the highest potential life loss rate (PYLLR: 2.80‰). Based on the average potential life loss, the order of life loss was liver cancer, colorectal cancer, lung cancer, and stomach cancer.
The standardized mortality rates for different types of malignancies showed an upward trend, with significantly higher rates for males than females. The proportion of deaths occurring in the 70-79 age group rose significantly, whereas that in the 40-49 age group declined. AYLL from malignant tumors showed an overall downward trend, while the PYLLR for lung, liver, and colorectal cancer increased, suggesting a growing impact on the life expectancy of residents with Hengshui household registration. These trends should be utilized to adjust malignancy prevention and control measures accordingly.
