title: A comparative analysis of breast cancer stage between women enrolled in the National Breast and Cervical Cancer Early Detection Program and women not participating in the program.
abstract: OBJECTIVE
  To determine the proportional distribution of early- and late-stage breast cancers diagnosed in years 2004-2009 among women enrolled in the National Breast and Cervical Cancer Early Detection Program (NBCCEDP) and to compare this distribution to that of geographically comparable non-enrolled women diagnosed with breast cancer.
  
  
  METHODS
  Using data from the National Program of Cancer Registries, we compared the demographic characteristics and cancer stage distribution of women enrollees and non-enrollees by use of conditional logistic regression using the odds ratio as a measure of association.
  
  
  RESULTS
  NBCCEDP enrollees were slightly younger and more likely to identify as African-American, API and AIAN than were non-enrollees. The proportion of late-stage breast cancer (regional and distant) decreased slightly over the study period. NBCCEDP enrollees generally were diagnosed at a later stage of breast cancer than were those not enrolled in the NBCCEDP.
  
  
  CONCLUSIONS
  The NBCCEDP has been effective in achieving its goal of enrolling racial and ethnic populations; however, enrollees had a poorer stage distribution of breast cancer than did non-enrollees underscoring the need to expand breast cancer control efforts among low-income, underserved populations.
