Core Tip

Core tip: Although extremely frequent, treatment-related gastrointestinal toxicities in patients with advanced colorectal cancer and pancreatic cancer are often underreported. As such, it is difficult to establish to what extent such toxicities affect both patient quality of life and cancer care costs. In our work we describe the main gastrointestinal toxicities as well as their pathophysiology and grading scales. Finally, based on the results of the main randomized clinical trials, we provide a critical update on their incidence with both chemotherapeutic agents and novel targeted drugs.
