Background . Cisplatin, 5‐fluorouracil (5‐FU), and leucovorin (PFL) chemotherapy has been reported to be effective in the treatment of cancers but severe mucositis or neutropenia are dose limiting toxicities. This Phase II study evaluated the anticancer effect and the toxicities of a new weekly 24‐hour infusional PFL chemotherapy in patients with nasopharyngeal carcinoma (NPC). Methods . Forty‐two patients with stage IV NPC were studied. Cisplatin 25 mg/m 2 /d, 5‐FU 2200 mg/m 2 /d, and leucovorin 120 mg/m 2 /d were administered weekly by 24‐hour intravenous continuous infusion in an outpatient setting. Clinical response and toxicity were evaluated weekly. Results . The complete response rate (CR) was 30% and the partial response (PR) rate 60% in the localized previously untreated group. The CR rate was 22.7% and PR rate 45.5% in local recurrent/metastatic group. The overall response rate was 79%. Eighty‐one percent of patients who had no previous chemotherapy and 67% of patients who had previous chemotherapy responded to weekly PFL. There were no dose limiting toxicities. No patient had grade 3 or 4 mucositis or neutropenia. Thirty‐two patients (76%) had no oral mucositis. Seven patients (17%) had grade 1 mucositis and 3 patients (7%) had grade 2 mucositis. Conclusions . Elimination of dose limiting toxicities is possible using a weekly 24‐hour infusion schedule of PFL chemotherapy while retaining significant anticancer activity as demonstrated in these patients with advanced NPC. To discover whether this schedule is superior to cisplatin and 5‐FU or other PFL chemotherapy regimens requires further investigation. Cancer 1995; 76:2186–92.
