Introduction: The aim of this study was to investigate and analyze the incidence of early-onset colorectal cancer in Arizona, using the Arizona Cancer Registry. Methods: We performed a retrospective analysis of patients with colorectal cancer reported in the Arizona Cancer Registry from 1995-2010. Outcome measure: incidence of CRC in patients younger than 50 years. Results: A total of 39,623 cases of colorectal cancer were reported to the Arizona Cancer Registry during a period of 15 years. Overall, there was a 17% decrease in the incidence of CRC. However, there was a 23% increase in incidence among patients in the age group 10-50. The most significant increase (102%) in overall CRC incidence was seen in the age group 10-29. The highest increase (110%) in incidence of colon cancer was observed in the same age group, while the most significant increase in incidence rates (225%) of rectal cancer was seen in the age group 30-34. Conclusion: Although there is an overall decrease in incidence of colorectal cancer in Arizona, alarming increase in incidence of early-onset CRC was observed; mirroring the national trends.
