Analysis of trends in cancer mortality and the years of life, which are lost in six provinces in northwestern China from 2013 to 2021

Trends in cancer mortality

From 2013 to 2021, the total population rose from six provinces in northwestern China from 28,920,573 to 29,374,940, in which a total of 280,967 deaths were recorded due to cancer, including 178,176 men and 102,791 women with 139,506 in urban areas and 141,461 in the Rural areas in the rural areas. In 2013 there were 24,333 deaths due to cancer with a rough mortality rate of 84.14/100,000 (95%CI 83.08/100,000-85.20/00,000) and an age-standardized mortality rate of 128.28/100,000 (95%CI : 128.09/9/9/9/100,000 (95%CI: 128.09/9/100,000-128.47/100,000) for cancer. 45/100,000) and an age -standardized mortality rate of 130.36/100,000 (95%CI: 130.17, 130.17, 130.17.

The rough death rate of cancer in the six provinces of Northwest China from 2013 to 2021 showed an increasing trend (AAPC = 3.96%, Pp = 0.928), however, showed a decreasing trend from 2017 to 2021 (AAPC = – 5.64%,, P= 0.047). From 2013 to 2021, the age -standardized mortality rate of men was consistently higher than that of women and was stable for both men and women as a whole. However, the age -standardized cancer rate in women showed an increasing trend from 2013 to 2017 (APC = 6.15%, P= 0.028) and showed a decreasing trend from 2017 to 2021 (APC = – 5.56%,, P= 0.032). The age-standardized mortality rate of cancer in rural and urban areas was stable overall, but the age-standardized mortality rate in urban areas showed a decreasing trend from 2015 to 2021 (APC = -4.80%,, P= 0.021), and the age -standardized mortality rate in rural areas showed an increasing trend from 2013 to 2019 (APC = 2.41%,, P= 0.010) and a decreasing trend from 2019 to 2021 (APC = – 8.53%,, P= 0.042) (Table 1).

From 2013 to 2021, all six northwestern provinces showed an increasing trend of the raw stability rate and a stable trend of the age -standardized mortality rate (Table 2).

Storing rate and cure trend according to age

In 2021, the mortality rate of cancer in the age groups from 0–14, 15–44, 45–64 and ≥ 65 years was 2.77/100,000, 11.33/100,000, 121.93/100,000 or 641.24/ 100,000. The cancer death rate in the entire population, different genders and various regions in the examination area rose low at the age of 45 and then gradually increased, which reached a highlight in the age groups from 80 to 84 and ≥ 85 years (Fig. 1 and 2).

From 2013 to 2021, Cancer Raw Dying rates showed a falling trend in the overall population, men, women and rural areas in the age group for 15 to 44 years and in the age groups of 0–14, 45–64, in the age groups from 0–14 , 45–64. and ≥ 65 years (Table 3).

However, the total population and men in the age group from 45 to 64 years showed a decreasing trend in 2017–2021 (APC = – 6.62% or – 6.64% PPP = 0.022).

In the age group ≥ 65 years, only urban areas showed a decreasing trend from 2015 to 2021 (APC = – 3.18%, P= 0.044).

Annual analysis of life expectancy and the years of life that have lost in six northwest provinces against cancer

Le rose by 1.01 years in the six northwestern provinces from 2013 to 2021, which is 0.87 years in rural areas (AAPC = 0.13%, P= 0.012) and 1.02, 0.91 and 0.86 years in men, women and urban areas with stable trends. Krebsceles rose by 1.06 years in the entire population; 1.07 and 0.95 years in men or urban areas with an increasing trend from 2015 to 2021 (APC = 0.45% or 0.71% P4).

From 2013 to 2021, total cancer increased among the residents of the six northwest provinces from 525,609.6 people to 640,313.7, and the YLL rate rose from 18.17 ° C in 2013 to 21.80 ‰ in 2021 with one increasing trend trend, which increases overall as an overall increasing trend towards Drank to increase. (AAPC = 2.16%, P= 0.001). The YLL rate of men was always higher than that of women. Ayll decreased from 21.60 years in 2013 to 19.25 years in 2021 with a total stable trend (AAPC = – 1.06%, P= 0.151). The YLL rate showed an increasing trend after gender and region (all PP. 5).

Contribution of changes in cancer mortality to changes in life expectancy according to the age group

In total, changes in cancer mortality in the six northwestern provinces contributed positively to the increase in life expectancy from 2013 to 2021, which contributed 0.217 years or 21.38% of the increase in life expectancy. Among the contribution values ​​for every age group, the biggest positive contribution was in 0 to 0

The change in cancer mortality in men contributed 0.248 years or 24.48% to increase life expectancy, with the greatest positive effect in 0 to largely

The contribution of the change in cancer mortality to increase life expectancy was smaller in women (0.163 years, 17.99%) than in men, with the greatest positive effect in 0 to

The change in urban cancer mortality contributed 0.225 years or 26.34% to increase life expectancy, with the greatest positive effect in the age group 60 to 64 years (0.046 years, 5.37%) and the greatest negative effect between ≥ 85 Years contributed ( – 0.0658 years, – 7.58%).

The contribution of the change in cancer mortality to increase life expectancy was smaller in rural areas (0.198 years, 22.65%) than in urban areas, with the greatest positive effect in 0 to 3).

Deaths and changes in the province of cancer and changes in the Pgles

From 2013 to 2021, Gansu Province had the highest Number of Cancer-Related Deaths at 76.615 (26.74%), Followed by Inner Mongolia Autonomous Region (69.162, 24.14%), Shaanxi Province (61,337, 21.40%), Ningxia Hui Autonomous region ( 32.367.

In 2013, Krebspgles in the six northwestern provinces in the autonomous region of Inner Mongolia (2.37 years) were the highest in the autonomous region of Ningxia Hui (1.98 years). In 2021, Krebspgles were the highest and lowest in the autonomous region of the inner Mongolia and in the autonomous Xinjiang Uyghur region (1.88 years). From 2013 to 2021, the Pgles in the province of Qinghai and the autonomous region of Xinjiang Uyghur (around 0.30 and 0.15 years) and increased in the remaining provinces with the highest increase in the province of Shaanxi (0.19 years) .
