Treatment of advanced head and neck cancer with concomitant radiation and chemotherapy.

Forty-four patients with predominantly inoperable or recurrent head and neck cancers were treated with combined chemotherapy (CT) and radiation therapy (RT) in a Phase I/II study. CT and RT were combined in a concomitant fashion to take advantage of radiosensitizing properties of the chemotherapeutic agents. Each treatment cycle consisted of cisplatin 60 mg/M2 on day 1, 5-FU infusion at a dose of 800 mg/M2 per day continuously for 5 days and RT at 200 cGy per day, days 1 through 5. The treatment cycle was repeated every 2 weeks for 7 cycles in patients treated curatively and for 2 to 6 cycles in patients treated palliatively due to prior radiation therapy or the presence of metastatic disease. Regional control was achieved in 98% of the patients. Regional control has persisted in 87% of the patients treated curatively with a minimum follow-up of 24 months. Distant failure occurred in 23% of this group. Actuarial survival of 2 years for the curative group is 66%. Concomitant combination of radiation with radiation potentiating chemotherapeutic agents shows promise of increase in local control.
