Mechanism of action

FOLFIRI combines fluorouracil (5-FU), leucovorin, and irinotecan (a topoisomerase I inhibitor that prevents DNA unwinding and repair). FOLFOX combines fluorouracil, leucovorin, and oxaliplatin (a platinum agent causing DNA cross-links). Both regimens are standard chemotherapy backbones for colorectal cancer that work through distinct mechanisms of DNA damage and inhibition of nucleotide synthesis.
