floxuridine + dexamethasone + heparin + oxaliplatin + capecitabine + leucovorin + fluorouracil

This is a complex combination chemotherapy regimen that includes multiple cytotoxic agents and supportive medications. The core components include: - **Oxaliplatin**: A platinum-based cytotoxic agent that forms DNA adducts, inhibiting DNA replication and transcription - **Fluorouracil (5-FU)**: A pyrimidine analog that inhibits thymidylate synthase, disrupting DNA synthesis - **Capecitabine**: An oral prodrug of 5-FU that is converted to the active drug in tumor tissues - **Leucovorin (folinic acid)**: A reduced folate that enhances the efficacy of 5-FU by stabilizing the binding of 5-FU to thymidylate synthase - **Floxuridine**: A fluorinated pyrimidine nucleoside that is metabolized to 5-FU - **Dexamethasone**: A corticosteroid used to prevent nausea and vomiting associated with chemotherapy - **Heparin**: An anticoagulant that may be included to prevent thrombotic complications This combination may be used in advanced colorectal cancer treatment protocols, potentially in specific clinical contexts requiring intensive therapy.
