Estimates and prediction on incidence, mortality and prevalence of breast cancer in China, 2008 / 中华流行病学杂志

Objective To estimate the incidence,mortality and 5-year prevalence of breast cancer in China,in 2008.Methods Data from 36 cancer registries and the Third National Death Survey in China (2004-2005) were used to estimate the incidence,mortality and 5-year prevalence of breast cancer in China in 2008.Mathematical models were used to predict the breast cancer incidence and mortality in the next 20 years.Results In 2008,the incidence of breast cancer was 169 452 (14.2％) with the incidence rate of 21.6/100 000,ranking the second among all the cancers.Deaths due to breast cancer was 44 908 (6.1％) with mortality as 5.7/100 000,which ranked the sixth among all the cancers.The 5-year prevalence rate of breast cancer in China was 120.8/100 000,taking up the proportion as 26.1％,ranking the first among all the cancers.Breast cancer was seen more frequently among people aged between 40 to 70.Our data on prediction showed that the incidence and mortality of breast cancer in China would gradually increase in the next 20 years.Conclusion Breast cancer was the second cause of incidence rates among all the cancers in China,with both increasing incidence and mortality.Population at most risk for breast cancer were those aged 40 to 70,who deserved special programs for prevention and control.

Estimates and prediction of prostate cancer incidence, mortality and prevalence in China, 2008 / 中华流行病学杂志

Objective To estimate the incidence,mortality and 5-year prevalence of prostate cancer in China,in 2008.Methods Data from 36 cancer registries and the Third National Death Survey in China (2004-2005)was used to estimate the incidence,mortality and 5-year prevalence rates of prostate cancer in China in 2008.Mathematical models were used to predict the incidence and mortality of prostate cancer in the next 20 years.Results In 2008,the incidence of prostate cancer was 33 802 (2.1％),with the incidence rate as 4.3/100 000,which ranked the eighth among all the male cancers.Mortality of prostate cancer in China was 14 297 (1.2％) with the mortality rate of 1.8/100 000,which ranked eleventh among all the male cancers.The 5-year prevalence rate of prostate cancer in China was 75 535 (3.5％) with the proportion of 13.8/100 000,ranking the seventh among all the male cancers.The incidence and mortality of prostate cancer in men before the age of 60 maintained at a low level,but rose rapidly after the age of 60.Data on prediction showed that the incidence and mortality of prostate cancer in China would gradually increase in the next 20 years.Conclusion Both incidence and mortality of prostate cancer in China would keep increasing in the future.Prevention and control programs for prostate cancer should be strengthened.
