To-date, 659 subjects have been enrolled. Study participation involves obtaining demographic, pathology and patient contact data on all colorectal cancer patients at the 14 participating sites and conducting a one-time telephone interview. Preliminary study data suggests that most veterans with colorectal cancer present with evidence of regional or distant spread of their colorectal cancer. No significant difference in stage at presentation among veterans versus the population-based SEER patients is evident. Fewer veterans present with localized disease (33% versus 40%) and, although not statistically significant, could suggest a trend toward presentation at a more advanced stage.
