Abstract
PURPOSE: Treatment of locally advanced head and neck carcinoma by surgery and/or radiotherapy is associated with a high recurrence rate, poor survival, and, often, limitation in speech and swallowing functions. Because prolonged time of treatment might be detrimental for tumor control, we designed a study to develop a schedule of alternating radiotherapy and chemotherapy that should be administered over the shortest period of time and with the highest dose of radiotherapy as possible. PATIENTS AND METHODS: Following four successive steps of schedule modifications, regimens alternating split hyperfractionated radiotherapy (2.0 Gy/d times three over 30 to 40 days, to a total of 48 Gy to 60 Gy) and chemotherapy (cisplatin 80 to 100 mg/m2 and fluorouracil 1,000 mg/m2 by continuous infusion for 3 to 4 days, +/- vindesine 8 mg/m2 for two cycles) were administered in 91 patients with advanced squamous cell carcinoma of the head and neck. Adenectomy was performed for residual nodes and major surgery for progression only. RESULTS: The overall response rate was 95.6% (95% confidence interval [CI], 89.1 to 98.8), with 69.2% complete and 26.4% partial responses. Among partial responders, two patients were converted into complete responders by resection of a residual node. With a median follow-up duration of 45 months, distant mestastases occurred in 18% and a second primary tumor in 7.7% of patients. The median overall survival (OS) and progression-free survival (PFS) durations were 24 months and 17 months, respectively. At 4 years, the survival rate was 40%. All of the locoregional recurrences occurred within the first 15 months, in 14% and 73% of the complete and partial responders, respectively. Mucositis was the dose-limiting toxicity, with a World Health Organization (WHO) grade III and IV rate of 81% at a 60-Gy dose of radiotherapy, compared with 65% at 48 Gy or 54 Gy, which precluded further dose escalation. Leukopenia was severe in the first two steps of treatment, with WHO grade IV toxicity occurring in 41% of patients; however, this decreased to 10% when vindesine was deleted from the chemotherapy regimen in the last two steps. Late toxicity in 29% of patients was not different from that expected with radiotherapy alone. Among patients with resectable tumors, a 64% rate of organ preservation was obtained. CONCLUSION: We demonstrated that a full dose of hyperfractionated radiotherapy alternated with chemotherapy over 40 days could produce high antitumor activity. Mucositis was the dose-limiting toxicity, but this resolved completely within a median period of 6 weeks.
