title: [Survival rate for breast cancer in Rabat (Morocco) 2005-2008].
abstract: BACKGROUND
  Breast cancer is a public health problem in Morocco. This study aims to estimate the survival rate for patients with breast cancer living in Rabat.
  
  
  METHODS
  We conducted a prognostic study of female patients with breast cancer diagnosed during 2005-2008, living in Rabat and whose data were recorded in the Rabat Cancer Registry. The date of inclusion in this study corresponded with the date on which cancer was histologically confirmed. Survival rate was estimated using the Kaplan-Meier method and the comparison between the different classes of a variable was made using the log rank test. The study of factors associated with survival was performed using the Cox model.
  
  
  RESULTS
  During the study period 628 cases of breast cancer were collected. Mortality rate was 19.9%. Overall 1-year survival rate was 97.1%, 89.2% at 3 years and 80.6% at 5 years. In multivariate analysis, breast cancer survival was statistically lower in patients over 70 years of age (p <0.001) with large tumor size (p < 0.001), advanced-stage adenopathies (p = 0.007), metastases (p < 0.001) and not using hormone therapy (p = 0.002).
  
  
  CONCLUSIONS
  Large tumor size and metastases are poor prognostic factors in breast cancer, hence the need to strengthen screening programs.
