INPUT: ['The incidence of colorectal cancer in young patients is increasing. It remains unclear if the disease has unique features in this age group.', 'This was a single-center, retrospective cohort study which included patients diagnosed with colorectal cancer at age ≤40\xa0years in 1997-2013 matched 1:2 by year of diagnosis with consecutive colorectal cancer patients diagnosed at age>50\xa0years during the same period. Patients aged 41-50\xa0years were not included in the study, to accentuate potential age-related differences. Clinicopathological characteristics, treatment, and outcome were compared between groups.', 'The cohort included 330 patients, followed for a median time of 65.9\xa0months (range 4.7-211). Several significant differences were noted. The younger group had a different ethnic composition. They had higher rates of family history of colorectal cancer (p\xa0=\xa00.003), hereditary colorectal cancer syndromes (p\xa0<\xa00.0001), and inflammatory bowel disease (p\xa0=\xa00.007), and a lower rate of polyps (p\xa0<\xa00.0001). They were more likely to present with stage III or IV disease (p\xa0=\xa00.001), angiolymphatic invasion, signet cell ring adenocarcinoma, and rectal tumors (p\xa0=\xa00.02). Younger patients more frequently received treatment. Young patients had a worse estimated 5-year disease-free survival rate (57.6\xa0 vs. 70\xa0%, p\xa0=\xa00.039), but this did not retain significance when analyzed by stage (p\xa0=\xa00.092). Estimated 5-year overall survival rates were 59.1 and 62.1\xa0% in the younger and the control group, respectively (p\xa0=\xa00.565).'] Colorectal cancer in young patients: is it a distinct clinical entity?
