  Colorectal cancer (CRC) is the third most frequent malignant disease in the
world. In some countries with established screening programs, its incidence and
mortality have decreased, and survival has improved. AIMS: To obtain reliable
data about the epidemiology of CRC in Chile, we analyzed the trends in the last
ten years and the influence of observable factors on survival, including
explicit guarantees in CRC treatment access (GES program).
  Publicly available data published by the Health Ministry and National
Institute of Statistics were used. Data were obtained from registries of
mortality and hospital discharges, making follow-up of the individuals
possible. Crude and age-standardized incidence and mortality rates were
calculated, and individual survival was studied by constructing Kaplan-Meier
curves. Finally, a Cox statistical model was established to estimate the impact
of the observable factors.
