Cyclophosphamide + Mitoxantrone + Paclitaxel + Thiotepa

This appears to be a chemotherapy combination regimen containing four different anticancer agents. The search results did not provide specific information about the exact combination of cyclophosphamide + mitoxantrone + paclitaxel + thiotepa together as a single regimen, but did offer details on individual components and their use in other combinations. Cyclophosphamide is an alkylating agent that works by damaging DNA and preventing cancer cells from dividing. Mitoxantrone is an anthracenedione antineoplastic agent that intercalates with DNA and inhibits topoisomerase II, preventing DNA repair and synthesis in cancer cells. Thiotepa is an alkylating agent that slows or stops the growth of cancer cells by interfering with DNA replication. Paclitaxel is a taxane that stabilizes microtubules, preventing cell division.
