title: Trends and Patterns of Late and Unstaged Lung, Colorectal, Female Breast, and Prostate Cancers among American Indians in the Northern Plains, 2002-2009.
abstract: BACKGROUND
  We investigated incidence and staging patterns of prostate, female breast, lung, and colorectal cancer among American Indians/Alaska Natives (AI/ANs) and non-Hispanic Whites (NHWs) in the Northern Plains.
  
  
  METHODS
  Cancer registry data (2002-2009) from Nebraska, North Dakota, and South Dakota were analyzed. Incidence rates were calculated and multivariate logistic regression analyses identified factors associated with unstaged versus staged and late-stage cancer cases versus early.
  
  
  RESULTS
  The incidence rate was higher among AI/ANs than NHWs for lung cancer (92.2 vs. 60.6 per 100,000). Compared with NHWs, AI/ANs were 2.0 times more likely to receive an unstaged diagnosis and 1.2 times more likely to receive a late-stage diagnosis. AI/ANs were significantly more likely than NHWs to receive an unstaged diagnosis.
  
  
  CONCLUSIONS
  Increased efforts are needed to reduce unstaged and late-stage diagnoses among Northern Plains AIs. Efforts to promote early detection of cancer should target younger AI/ANs.
