Early-Onset Colorectal Cancer Patients Too Young for Screening

Early-Onset Colorectal Cancer Patients Too Young for Screening: Outcomes and Treatment Patterns

This is a population-based retrospective study using the Surveillance, Epidemiology, and End Results (SEER) registry and National Cancer Data Base (NCDB) to look at colorectal cancer (CRC) patients younger than 35 and comparing them against CRC patients older than 35 years of age.

Specifically, investigator want to investigate the effect of having a diagnosis of CRC before the age of 35 years on:disease stage at presentation, insurance status at diagnosis, treatment patterns by stage, and adjusted cancer-specific survival. The hypothesis is that patients younger than 35 years of age with CRC will present with more advanced disease at diagnosis but will have longer survival overall through more aggressive therapy.
