Abstract

Colon cancer is relatively asymptomatic in the early stages, the manifestations appearing and intensifying with the evolution of the disease, especially when associated with local and/or systemic complications. In such cases, surgical interventions are often emergency and involve more extensive operations (on metabolically and immune-stressed organisms), so that an early diagnosis (endoscopy, tumor markers, etc.) remains not only desirable but even a priority, especially in predisposed patients (genetic factors, lifestyle, etc.). As a consequence, the involvement of tumor markers in colon neoplasms has become more and more investigated in recent times. This review investigates the roles of serological and genetic markers in the management of patients with colon cancer, focusing on carcinoembryonic antigen, mismatch repair deficiency (dMMR), as well as KRAS and BRAF mutations. As a preliminary conclusion, tumor biomarkers seem to have a significant contribution to the diagnosis, decisions related to operative management, prognosis and postoperative follow-up of colon cancer, both in the categories of patients from high-risk groups and those without a clear predisposition to this condition.
