[Research progress of diagnosis and treatment of early-onset colorectal cancer].

Abstract

In recent years, the incidence rate of early-onset colorectal cancer (EOCRC) continues to rise, but its pathogenesis is still unclear. EOCRC is different from late-onset colorectal cancer in terms of the clinical and molecular pathological features, but their treatment strategies are the same, due to a lack of specific guidelines of screening, diagnosis and treatment for EOCRC. This article summarizes the research progress of epidemiological characteristics, risk factors, clinical features, molecular pathological features, pathogenesis, and prevention and screening strategies for EOCRC, in order to provide theoretical basis for the clinical treatment of patients with EOCRC.
