Why stopped (as posted): The study was terminated due to difficulties in including patients because of the slow rate at which patients met the established treatment profile at the proposing institution.
Summary
Brief summary (as posted)
Oral mucositis is the most significant acute toxicity of oral cavity radiotherapy. The available scientific evidence supports its preventive and therapeutic approach with low-level laser; however, this is unsuitable for tumor regions due to the risk of stimulating cellular metabolism. In this sense, an alternative treatment becomes necessary. Based on the preliminary results of the phase I study, a double-blind, randomized phase II study is suggested to evaluate the effectiveness of copaiba-based mouthwash in the prevention of oral mucositis in patients undergoing radiotherapy for oral cavity tumors. Patients will be randomized into 2 groups: A (copaíba) and B (placebo) and will use the mouthwash 4x/day. Each group will have 20 patients and be blind to the group in which they are included. They will be evaluated daily by a dental surgeon about oral mucositis, pain in the oral cavity and oropharynx, and dysphagia and will undergo daily laser therapy sessions, until the end of radiotherapy.
