Trend analysis of the incidence of prostate cancer in cancer registration areas of China between 1988 and 2015 / 中华泌尿外科杂志

ABSTRACT

Objective:To investigate the trend of prostate cancer incidence in Chinese tumor registration areas between 1988 and 2015.Methods:Collect the data including number of males, prostate cancer incidence rate and age-standardized incidence rate by world standard population(ASIRW) in Chinese tumor registration areas between 1988 and 2015. Calculate the average annual increase rate, and evaluate the trend of changes in the incidence of prostate cancer in China.Results:From 1988 to 2015, the number of male population covered by Chinese tumor registration areas increased from 10.41 million to 162.76 million, an average annual increase of 10.72%.The incidence of prostate cancer increased from 1.71 per 100 000 to 10.39 per 100 000, with an annual percentage change of 6.91%. The ASIRW increased from 1.82 per 100 000 to 6.05 per 100 000, with an average annual increase of 4.55%. In 1988—1997, 1998, 1999—2008, 2009—2010, and 2011—2015, the average annual increase rate of the male population covered by Chinese tumor registration areas was 0.99%, 36.73%, 7.92%, 37.55%, and 20.88% respectively. The average annual increase rate of prostate cancer incidence was 8.43%, -0.75%, 12.08%, -9.74%, 3.01%, and the average annual increase rate of ASIRW was 5.94%, -6.01%, 8.88%, -7.04%, 0.78%, respectively.Conclusions:The incidence of prostate cancer in Chinese tumor registration areas increased gradually during the early era of epidemiological investigation, followed by a rapid increase and a subsequent mild increase. With the rapid changes in the national cancer registration area and the population covered, the incidence of prostate cancer has declined in a short period of time.
