Mechanism of action

XELOX (capecitabine + oxaliplatin) is a standard chemotherapy doublet where capecitabine is a fluoropyrimidine prodrug that inhibits thymidylate synthase and gets incorporated into DNA/RNA, while oxaliplatin is a platinum agent that forms DNA crosslinks. When combined with radiotherapy (RT), the chemotherapy acts as a radiosensitizer to enhance tumor cell killing through multiple mechanisms of DNA damage.
