Abstract:
Objective:To analyze the trend of cancer incidence and age changes among men in cancer registration areas of China from 2000 and 2014.
Methods:We select the information of national cancer registry with continuous data from 2000 to 2014, review and organize the monitoring data at the above registries. A total of 22 monitoring registries were included in this study. The covering population of male were about 314 330 648 person years. The information on the incidence of all male prostate cancer patients with C61 was extracted from the International Classification of Diseases-10th Revision (ICD-10). To understand the incidence of male prostate cancer in each year, the age-standardized rate by Chinese population (ASR), average annual percent change (AAPC), adjusted mean age at onset were calculated. Incidence rates stratified by regions and age groups were also calculated. The linear regression model was employed to analyze the relationship between mean age at onset and year.
Results:The prostate cancer incidence in China increased by 11.5% (95%CI: 10.3%-12.7%) from 2000(4.62/100 000) to 2014(21.62/100 000), the age-standardized incidence rate increased by 7.1% (95%CI: 6.0%-8.1%) and the growth of rural was greater than that of urban. The age-specific incidence showed that the incidence rate increased significantly among the age group of 50 years; the incidence rates in men who have the same age but with different birth years showed a significant increase as birth years increased. The adjusted mean age at diagnosis of prostate cancer in cancer registry areas was 74.09 years old in the year of 2000, reduced by 0.13 year old to 72.35 years old in 2014 (β=-0.13, P<0.001). The adjusted mean age at onset declined significantly over time in urban areas (β=-0.13, P<0.001).
Conclusion:The trend of prostate cancer incidence among men in cancer registry regions generally increased, and the average age at diagnosis declined slightly from 2000 to 2014.
