The activity of a single-agent 5-fluorouracil infusion in advanced and recurrent head and neck cancer.
Although chemotherapy regimens using cisplatin (CDDP) and 5-fluorouracil (5-FU) infusion have shown significant activity in advanced and recurrent head and neck cancer, their use requires normal renal function. The use of 5-FU infusion alone has not been evaluated in these tumors. Retrospective analysis revealed 11 patients who received 5-FU infusion alone because of poor renal function: 7 patients with recurrent disease who were previously treated with surgery and/or radiation therapy and 4 patients who received 5-FU as preoperative induction therapy for advanced disease were treated. The infusion dose consisted of 1000 mg/M2/24 hours for 96 hours for patients with previous radiation and 120-hour infusions for patients without previous radiation. The courses were repeated at 3-week intervals. Eight of 11 (72%) demonstrated a response (1 complete response [CR] and 7 partial responses [PRs]. Responses occurred in 4 of 4 (all PRs) patients with previously untreated epidermoid cancer, 1 patient with recurrent adenocystic cancer, and 3 of 6 patients with recurrent epidermoid cancer not previously treated with chemotherapy. Three patients, with no prior systemic or local therapy, who were clinical partial responders to 5-FU infusion went on to surgery and radiotherapy. Their responses were maintained for 18, 14, and 46+ months, respectively. The predominant toxicities were stomatitis (6/11, 55%) and leukopenia (2/11 patients). In this retrospective analysis, 5-FU infusion alone demonstrated good activity in head and neck cancer with tolerable toxicity. Since the number of patients is small and were selected on the basis of renal function, prospective evaluation is essential.
