BACKGROUND: Over the past years, the incidence of colorectal cancer has been increasing among young adults. A large percentage of these patients live at least 5 years after diagnosis, but it is unknown whether their rate of hospitalizations after this 5-year mark is comparable to the general population. METHODS: This is a population-based cohort consisting of 917 young adult survivors diagnosed with colorectal cancer in Ontario from 1992-1999 and 4585 matched cancer-free controls.
