Abstract:
Objective: To analyze the incidence and mortality of colorectal cancer in Jiangsu province in 2015. Methods: Based on the method and criteria of data quality control from the National Central Cancer Registry, data in 2015 from 42 cancer registries in Jiangsu were evaluated by the Jiangsu Provincial Center for Disease Control and Prevention. Data from 35 registries were qualified after assess-ment and accepted as pooled data. Stratified by urban-rural, gender, and age groups, the crude rates of colorectal cancer incidence and mortality, age-standardized incidence/mortality rates, age-specific incidence/mortality rates, cumulative incidence/mortality rate (0-74 years old), and truncated age-standardized incidence/mortality rate (35-64 years old) were calculated. The Chinese population census in 2000 and Segi's standard world population were used for age-standardized incidence/mortality rates. Results: The 35 cancer registries covered a population of 38,761,144 (15,168,594 in urban areas, 23,592,550 in rural areas) in Jiangsu province in 2015. The number of new cases of colorectal cancer were 11,051, with a crude incidence rate of 28.51/105. The age-standardized incidence rates by the Chinese Standard Population (ASRC) and World Standard Population (ASRW) were 15.43/105 and 15.20/105, respectively. The cu-mulative incidence rate (0-74 years old) was 1.81%, with a truncated age-standardized incidence rate (35-64 years old) of 23.71/105. The crude and ASRC incidence rates in urban areas were 33.87/105 and 18.44/105, respectively, whereas those in rural areas were 25.06/105 and 13.54/105, respectively. The number of deaths due to colorectal cancer was 5,436, with a crude mortality rate of 14.02/105. The ASRC, ASRW, cumulative (0-74 years old), and truncated (35-64 years old) mortality rates were 6.92/105, 6.81/105, 0.70%, and 8.08/105, respectively. The crude and ASRC mortality rates in urban areas were 16.57/105 and 8.27/105, respectively, whereas those in rural areas were 12.39/105 and 6.07/105, respectively. Conclusions: There remains a heavy burden of colorectal cancer in Jiangsu. The incidence and mortality of colorectal cancer show a rising trend in Jiangsu in 2015. The burden and patterns of colorectal cancer show urban-rural differences. Preventative and control strategies should be implemented.
