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

• Conditions: Nasopharyngeal Carcinoma

• Registration Number: NCT04764149
• Lead Sponsor: Sun Yat-sen University

Brief Summary

Local control rates of nasopharyngeal carcinoma are increasing, but 15% of patients still have local recurrence within 5 years after initial treatment. Systematic treatment based on chemotherapy has become the mainstream approach for recurrent nasopharyngeal carcinoma which is intolerant to local therapy. 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.

Detailed Description

Nasopharyngeal carcinoma (NPC) is a malignant tumor of the nasopharyngeal epithelium with high sensitivity to ionizing radiation, but failure in local control was observed in approximately 15% of patients.

Chemotherapy is the cornerstone of the treatment of recurrent NPC. Many studies were aimed at the systemic treatment of recurrent NPC, but most of them were retrospective studies or phase II trials with small samples. Platinum-containing doublet chemotherapy is generally regarded as the standard treatment for recurrent NPC. After a multicenter phase III randomized clinical trial was published in 2016, gemcitabine plus cisplatin is recommended, however, less than 60% of patients could complete the treatment in the trail. Finding a proper regimen with promising efficacy results as well as high tolerance is still a big challenge.

Cisplatin plus 5-fluorouracil (PF) is a classical regimen widely used in recurrent NPC. The continuous infusion of 5-fluorouracil with low dose was investigated in esophagus carcinoma, rectal carcinoma and prostate carcinoma with encouraging outcome and acceptable toxicity. Whereas, data of platinum containing chemotherapy with low-dose continuous infused 5-fluorouracil in recurrent NPC was absent. In this study, we aimed to investigate the antitumor activity of platinum plus low-dose long-term continuous intravenous infused 5-fluorouracil (PFLL).
