Analysis on mortality and burden of colorectal cancer in residents in Beijing, 2010–2015

Objective To analyze burden of colorectal cancer in residents in Beijing from 2010 to 2015, and provide evidence for colorectal cancer prevention and control.

Methods The data of colorectal cancer deaths in permanent residents in Beijing from 2010 to 2015 were collected, and the burden of colorectal cancer was analyzed according to the mortality, standardized mortality, cause eliminated life expectancy, and years of life lost (YLL).

Results The mortality rate of colorectal cancer in residents in Beijing increased from 14.40/100 000 in 2010 to 17.58/100 000 in 2015, an increase of 22.08% (28.75% in men and 14.14% in women). The standardized mortality rate of colorectal cancer increased from 9.67/100 000 in 2010 to 9.76/100 000 in 2015, an increase of 0.93% (an increase of 5.34% in men, but a decrease of 4.64% in women). The life expectancy after eliminating the death from colorectal cancer increased from 81.05 years in 2010 to 82.25 years in 2015, and the loss of life expectancy due to colorectal cancer increased from 0.24 years in 2010 to 0.30 years in 2015. The YLL per 100 000 people caused by colorectal cancer increased from 154.75 person years in 2010 to 173.06 person years in 2015, an increase of 11.83% (19.71% in men and 2.19% in women).

Conclusion The mortality and standardized mortality of colorectal cancer in residents in Beijing showed an upward trend. The loss of life expectancy and the burden of disease caused by colorectal cancer increased year by year, indicating that colorectal cancer is an important disease affecting the life and health of residents in Beijing.
