OBJECTIVE To provide evidence for breast cancer prevention and control through epidemiological analysis of the incidence, mortality and survival rate of female breast cancer patients in Beijing. METHODS The female registration data in the Beijing urban area from 1982 to 2001 were retrospectively reviewed. The incidence, mortality and survival rate of female breast cancer patients were analyzed using routine and life-table statistical methods. RESULTS During the period of 1982 to 2001, there was a trend of an average annual increase of female breast cancer incidence of 4.6% in urban Beijing, and of 4.9% in the world-population standardized incidence. The epidemiological features of urban Beijing female breast cancer showed:(1)The incidence distribution of different age groups from 25 to 80 years elevated with two peaks at ages of 45~ and 70~ years; (2)There was an elevation in each age group over the last 20 years; (3)The incidence rate at ages of 35 to 64 reached 95.3/105, causing breast cancer to become the number one cancer in females. The changes in the survival rate showed the following: the 5-year observed survival rate (OSR) increased from 62.0% in 1982~1983 to 68.7% in 1987~1988, and the relative-survival rate (RSR) increased from 66.3% to 74.2%. The 10-year OSR and RSR in 1987~1988 were 60.3% and 65.1%, and at 15 years 57.5% and 61.3%, respectively. The mortality rate of breast cancer patients fluctuated from 8 to 10 per 105 population over the 20 years of study. CONCLUSION There is a trend of an annual increase in female breast cancer in Beijing. The 5-year survival is being improved gradually while the mortality remains stable. The results demonstrate that the principles of “early prevention, diagnosis and treatment” for breast cancer are effective in Beijing. OBJECTIVE To provide evidence for breast cancer prevention and control through epidemiological analysis of the incidence, mortality and survival rate of female breast cancer patients in Beijing. METHODS The female registration data in the Beijing urban area from 1982 to 2001 were retrospectively reviewed. The incidence, mortality and of female breast cancer patients were analyzed using routine and life-table statistical methods. RESULTS During the period from 1982 to 2001, there was a trend of an average annual increase of female breast cancer incidence of 4.6% in urban Beijing, and of 4.9% in the world-population normal incidence. The epidemiological features of urban Beijing female breast cancer showed: (1) The incidence distribution of different age groups from 25 to 80 years elevated with two peaks at ages of 45 ~ and 70 ~ years; (2) There was an elevation in each age group over the last 20 years; (3) The incidence rate of ages 35-64 reached 95.3 / 105, causing brea The changes in the number of cancer in females. The changes in the survival rate showed the following: the 5-year observed survival rate (OSR) increased from 62.0% in 1982 ~ 1983 to 68.7% in 1987 ~ 1988, and the relative -survival rate (RSR) increased from 66.3% to 74.2%. The 10-year OSR and RSR in 1987 to 1988 were 60.3% and 65.1%, and at 15 years 57.5% and 61.3%, respectively. The mortality rate of breast cancer The patients fluctuated from 8 to 10 per 105 population over the 20 years of study. CONCLUSION There is a trend of an annual increase in female breast cancer in Beijing. The 5-year survival is being rampant the the mortality remains stable. The demonstrates that the principles of “early prevention, diagnosis and treatment ” for breast cancer are effective in Beijing.
