Platinum Plus Low-dose Long-term Continuous Intravenous Infused 5-Fluorouracil in Metastatic Nasopharyngeal Carcinoma

The treatment of distant metastasis is a key challenge for nasopharyngeal carcinoma because of poor outcomes, among which, chemotherapy is the cornerstone. However, many studies reported the use of different chemotherapy regimens to prolong the survival of metastatic nasopharyngeal carcinoma, while few of them focused on how to reduce the side effects of chemotherapy or improve the life quality of patients. Thus, we sought to find an efficient chemotherapy regimen with high tolerance according to the characteristics of chemotherapy drugs, that is, to explore the efficacy and safety of platinum plus 5-fluorouracil with continuous intravenous infusion at a low dose for a long term.
