Irinotecan-based chemotherapy is a fundamental cytotoxic regimen for advanced colorectal cancer. The disposition of irinotecan is known to vary in a fashion partially depending on genetic variations in the drug metabolic pathways. UDP-glucuronosyltransferase (UGT)1A1 is a predominant enzyme that converts the active metabolite of irinotecan to the inactive form via a glucuronidation process. Several UGT1A1 polymorphisms are linked to SN-38 glucuronidation and irinotecan-related adverse events,
