title: Incidence, mortality and survival of female breast cancer during 2003-2011 in Jiangsu province, China.
abstract: OBJECTIVE
  To assess the incidence, mortality and survival status of female breast cancer in Jiangsu province of China.
  
  
  METHODS
  Population-based cancer registry data in Jiangsu province were collected during 2003-2011. Crude rates, age-specific rates, age-standardized rates and annual percent changes of incidence and mortality were calculated to describe the epidemiologic characteristics and time trends. Patients diagnosed from 2003 to 2005 were chosen for analyzing the survival status of breast cancer.
  
  
  RESULTS
  From 2003 to 2011, 17,605 females were diagnosed with breast cancer and 4,883 died in selected registry areas in Jiangsu province. The crude incidence rate was 25.18/100,000, and the age-standardized rates by Chinese population (ASRC) and by world population (ASRW) were 19.03/100,000 and 17.92/100,000, respectively. During the same period, the crude mortality rate was 6.98/100,000 and the ASRC and ASRW were 4.93/100,000 and 4.80/100,000, respectively. From 2003 to 2011, the incidence and mortality increased with annual percent change of 11.37% and 5.78%, respectively. For survival analysis, 1,392 patients in 7 areas were identified in 2003-2005 and finished 5 years of follow-up. Survival rates were found to decrease with survival years, the 5-year observed survival rate was 45.9% and the relative survival rate was 52.0%. We also found that the survival rate varied across the province, which was lower in the north and higher in the south of Jiangsu province.
  
  
  CONCLUSIONS
  Breast cancer has become a significant public health problem in Jiangsu province and China. More resources should be invested in primary prevention, earlier diagnosis and better health services in order to increase survival rates among Chinese females.
