Trend of incidence and mortality on prostate cancer from 2009 to 2014 in Shaoxing, Zhejiang Province / 中华泌尿外科杂志

ABSTRACT

Objective To analyze the incidence and mortality of prostate cancer and its time trend from 2009 to 2014 in Shaoxing of Zhejiang province.Methods The data of prostate cancer in Shaoxing from 2009 to 2014 was collected to calculate the incidence,age-standardized incidence rate by Chinese standard population (ASR China) or by world standard population (ASR world) and percentage change (PC) of incidence.The annual percentage change (APC) of incidence was estimated by linear regression based on the logarithm of the incidence rates observed.Results During 2009-2014,a total of 1 417 new cases in Shaoxing were diagnosed as prostate cancer,and the average age was 74.14 ± 9.20 years.The crude incidence of prostate cancer was 10.74/100 000 (ASR China 4.06/100 000,ASR World 5.94/100 000).Mortality of prostate cancer in Shaoxing was 499 with the crude mortality rate of 3.78/100 000 (ASR China 1.25/100 000,ASR World 2.03/100 000),and the average age was 75.57 ± 8.21 years.The crude incidence of prostate cancer increased from 6.66/100 000 in 2009 to 17.00/100 000 in 2014 (APC =21.41％,P ＜ 0.05),while the APC values of ASR China and ASR World were 14.91％ (P ＜0.05) and 15.37％ (P ＜ 0.05),respectively.The crude mortality rate increased from 2.28/100 000 to 6.56/100 000 (APC =22.63％,P ＜0.05),while the APC values of ASR China and ASR World were 16.42％ (P ＞ 0.05) and 14.57％ (P ＞0.05),respectively.In Shaoxing,new cases and deaths of prostate cancer were never found among men younger than 40 years,but the incidence and mortality rate began to rise from the age of 40,with a rapid rise appearing after 50 years of age,and the incidence and mortality rate both reached the peak value (158.11/100 000 and 111.42/100 000) in the group of older than 85 years at last.Conclusions Although the incidence and mortality rate of prostate cancer were low in Shaoxing,but they had increased by time from 2009 to 2014.Elderly male population was the people at high risk of prostate cancer;specific corresponding measures should be taken to strengthen the prevention and control of prostate cancer.
