Stopped: insufficient recruitment, the planed sample size appears not achievable
The purpose of this study is to evaluate the benefit of a mouthwash with a phytopharmaceutical preparation, Homeodent®, compared to a mouthwash solution containing sodium bicarbonate, for prevention of severe mucositis (grade ≥3, RTOG classification) in patients receiving irradiation for oral cavity, oropharynx, hypopharynx or cavum cancer. This is a phase III, controlled, randomized, single blind study. The estimated inclusion period is approximately 24 months. The number of patients required in this monocentric study is 330 (165 per arm).
