Core Tip

Core Tip: We evaluated differences in tumor biology between young-onset colorectal cancer patients (< 50 years of age) and late-onset colorectal cancer (CRC) patients (≥ 50 years of age) in a Swiss tertiary cancer center over a six-year period. Parameters of interest included clinical as well as histopathological characteristics. This study reports a surprisingly high rate of CRC of young-onset, while affected patients present more frequently with locally advanced tumors, lymphatic invasion and with more frequent lymphatic metastases. This work puts cancer incidence in relation to histopathological details, mutational status, surgical parameters and selected risk factors.
