PURPOSE: This study was designed to characterize the entity of colorectal cancer (CRC) in young patients and to evaluate whether it has any unique epidemiological or clinicopathological features.
METHODS: The study population consisted of all consecutive young (≤50 years old at diagnosis) patients with CRC who were diagnosed during the years 1997-2007 and were treated at our institution, and a matching group of patients (>50 years at diagnosis). The medical files of these patients were reviewed, and the epidemiological, clinical, and pathological features of both groups were compared.
RESULTS: There were 406 patients: 203 in each group. The features of the older group were typical for patients with CRC, but the younger group showed female predominance, different ethnic composition, prevalence of family history of cancer and hereditary CRC syndromes, and lower incidence of polyps. The incidence of left-sided tumors and advanced stages (III-IV) at diagnosis was higher in the younger patients. Mucinous/signet ring histology, grade, stage, lymphatic and vascular invasion were all predictive of survival, whereas age was not.
CONCLUSIONS: Colorectal cancer in young patients was found to display a cluster of unique characteristics but fewer than previously reported and young age by itself was not found to impact patient outcome.
