Advanced head and neck cancer: response to and toxicity of multimodality therapy

This pilot study for resectable stage III and stage IV squamous cell carcinoma of the head and neck used a cytoreduction phase of preoperative radiation with cisplatin, followed by an eradicative treatment phase with radical surgery (group 1) or radical dose radiation and cisplatin (group 2), followed by adjuvant chemotherapy with 5-fluorouracil infusion and cisplatin delivered at 4-week intervals for six cycles following initial radiation therapy to the primary site. A total of 43 patients were treated between January 1984 and January 1987; 14 were classified with stage III carcinoma, 28 with stage IV, and one patient was not staged. Out of 43 patients, two did not complete therapy. Forty-one patients completed the eradicative phase of treatment. Complete tumor clearance at the end of the eradicative treatment phase was 88% (36 of 41 patients), 95% (18 of 19) in group 1 and 82% (18 of 22) in group 2. Actuarial recurrence-free survival was 61% at 3 years. Among 36 patients with complete tumor clearance after the eradicative treatment phase, there was no statistically significant difference for overall and recurrence-free survival between group 1 and group 2. In general, toxicity was not excessive, although mucositis, weight loss, and hematologic and neurologic toxicity were observed in varying degrees in these patients.
