Abstract

PURPOSE:

We report colon cancer survival rates that are conditioned on patients having already survived one or more years after diagnosis. These rates have more meaning clinically, because they consider those patients who have already survived a given period of time after treatment.

METHODS:

The life table method was used to compute conditional survival rates, using population-based data obtained from the Surveillance, Epidemiology, and End Results Program of the National Cancer Institute. Patients were diagnosed between 1983 and 1987 and followed up through 1994. Relative and observed survival rates are considered.

RESULTS:

Survival rates up to ten years after diagnosis are reported by stage of disease, gender, and race for colon cancer patients who survived from one to five years after diagnosis. Survival rates are also reported by lymph node involvement.

CONCLUSIONS:

Five-year and ten-year survival in colon cancer patients having already survived between one and five years after diagnosis continues to be influenced significantly by stage and race.
