    Abstract:
    Twenty-one patients with Stage III or IV head and neck epidermoid cancer were treated by a three-fractions per day radiotherapy regime plus misonidazole (MIS). An initial course of 45 Gy was used, spread over 12 days and divided into 30 fractions 1.5 Gy each with a 3-hour interval between fractions. A daily MIS dose of 1 g/m2 was given 2 hours prior to the first fraction. A boost dose of 22.5 Gy/5 days was given to 10 patients, 4 weeks after the initial course, using the same fractionation scheme. The local acute and chronic reactions were acceptable. Eight patients suffered mild reversible peripheral neuropathy. The mean MIS blood level corresponded to an enhancement ratio of about 1.45. The 1-year disease-free survival rate was 9/21 and was significantly greater in patients receiving the boost irradiation. The control rate of nodal disease was encouraging. Based on this pilot study, a prospective trial is proposed aiming at testing the usefulness of MIS in MDF regimens in advanced head and neck cancer, either as the sole method of treatment or as a preoperative measure.
