Analysis on prostate cancer incidence and mortality in Shanghai 2016 and trends of 2002-2016 / 肿瘤

ABSTRACT

Objective:To analyze the incidence and mortality of prostate cancer in Shanghai in 2016 and trends during 2002-201 6,and to provide a basis for prostate cancer prevention and treatment. Methods:The data of prostate cancer incidence and mortality in Shanghai from 2002-2016 were obtained from the Population-Based Cancer Registry and Vital Statistics of Shanghai Municipal Center for Disease Control and Prevention.The incidence,mortality,proportion,crude rate,age-specific rate and age standardized rate of prostate cancer were calculated.Age-standardized incidence and mortality were calculated using Segi's 1960 world standard population.Trends of prostate cancer incidence,mortality,age-standardized rate and age-specific rate were estimated by Joinpoint 4.9.1.0 software. Results:In 2016,there were 3 226 cases of newly diagnosed prostate cancer and 1 067 deaths in Shanghai,crude rate of incidence was 44.91/105,crude rate of mortality was 14.85/105,age-standardized incidence and mortality were 15.47/105 and 4.34/105.Age-specific incidence and mortality increased with age,and reached the highest level in the 80-84 year-old group and 85-year-old group.Urban incidence was higher than suburb in the 50-54 year-old group,75-79 year-old group,and 80-84 year-old group,with no statistical difference in mortality.Between 2002 and 2016,incidence and mortality increased gradually,the rise of age-standardized incidence slowed down after 2012,and the age-standardized mortality in urban area declined after 2012.The age-standardized incidence in suburb increased faster than that in urban area,and the incidence rate increased faster in the younger age groups. Conclusion:The incidence and mortality of prostate cancer in Shanghai were lower than the world level but higher than the national level,and the incidence increased gradually between 2002 and 2016.Incidence and mortality were higher in urban area than in suburb,but increased faster in suburb,and the incidence increased more rapidly in younger age groups,but the proportion of early stages at diagnosis was still low,suggesting that appropriate screening strategies should be considered.
