taxane + irinotecan + fluoropyrimidine

This is a combination chemotherapy regimen consisting of three classes of cytotoxic agents frequently used in the treatment of advanced gastrointestinal cancers, particularly metastatic gastric and colorectal cancer. The regimen includes: - A taxane (such as paclitaxel or docetaxel), which stabilizes microtubules and inhibits cell division. - Irinotecan, a topoisomerase I inhibitor that prevents DNA unwinding and replication. - A fluoropyrimidine (such as 5-fluorouracil or capecitabine), which inhibits thymidylate synthase, disrupting DNA synthesis. This combination is typically used in patients who have previously been treated with other regimens containing these agents individually or in different combinations. It is not marketed under a unique brand name but represents a multi-agent protocol tailored for refractory or advanced-stage disease[4][6]. The specific drugs within each class may vary depending on institutional protocols and patient factors.
