Five-year overall survival of early- and late-onset colorectal cancer in Medellín, Colombia: a comparative study.

Purpose: Early-onset colorectal cancer (CRC) (EOCRC, < 50 years) has distinct clinicopathological features from late-onset CRC (LOCRC, ≥ 50 years). However, evidence on survival outcomes is contradictory. We aimed to analyse the differences in 5-year overall survival (OS) between EOCRC and LOCRC.

Clinical and pathological differences between early- and late-onset colorectal cancer and determinants of one-year all-cause mortality among advanced-stage patients: a retrospective cohort study in Medellín, Colombia.

Objective: To identify the differences between early- (EOCRC) and late-onset colorectal cancer (LOCRC), and to evaluate the determinants of one-year all-cause mortality among advanced-stage patients.

Methods: A retrospective cohort study was carried out. CRC patients ≥ 18 years old were included.
