Abstract Background Most studies that have identified variables associated with the health-related quality of life HRQL of patients with colorectal cancer have been cross-sectional or included patients with other diagnoses.

Methods We conducted a population-based longitudinal study of patients identified through three regions of the California Cancer Registry. Surveys were completed by 568 patients approximately 9 and 19 months .
