Analysis of the incidence and mortality trend of breast cancer in Chinese women from 2005 to 2013 / 中华疾病控制杂志

ABSTRACT

@# Objective To Analyze the change trend of the incidence and mortality of breast cancer in Chinese women from 2005 to 2013 in the Chinese Cancer Registry Annual Report in order to provide references for the implement of the prophylaxis and treatment of breast cancer. Methods Extracted all the records of the incidence and mortality of breast cancer in Chinese women from 2005 to 2013, applied the Joinpoint regression model to analyze the change trend of the incidence and mortality of breast cancer in Chinese women. Results The incidence levels of breast cancer among urban women in China was higher than that in rural from 2005 to 2013, the change trend of urban incidence was stable(t=-0.2, P=0.828), the rural incidence showed an increasing trend(t=7.8, P<0.001). The peaks of urban and rural incidence were in the age group of 50- and the age group of 45- respectively.The mortality of breast cancer among urban women in China was higher than that in rural from 2005 to 2013, the change trend of urban mortality was stable(t=0.8, P=0.458), and the rising trend of rural mortality was obvious(t=3.3, P=0.014). The mortality of urban women began to rise after the age of 30, accelerating to rise after the age of 75, the mortality of rural women began to rise after the age of 30, the change tended to be stable at the age of 55-69, and began to rise after the age of 70 again. Conclusions The incidence and mortality of breast cancer among urban women in China were all higher than that in rural from 2005 to 2013, the rising trend of the incidence and mortality of breast cancer among rural women was obvious, so the prophylaxis and treatment measures of breast cancer should be actively formulated and perfected.
