Abstract :

Oral care is an important aspect in the quality of life of patients undergoing radiation therapy for oral cancer. Oral mucositis are commonly seen in this group of patients. Propolis has anti-inflammatory, antifungal, antibacterial, antioxidative, and anesthetic properties and it has been used worldwide as an alternative medicine for the treatment of various conditions. This phase II study was to determine the effectiveness of a Mucoadhesive Brazilian propolis gel in the prevention of radiation- induced oral mucositis. Twenty-four patients who were selected to undergo radiation therapy for oral cancer were included. They were advised to use a mucoadhesive gel containing propolis 5,0% w/v three times a day starting one day before the course of radiation therapy and concluding after 2 weeks of radiation therapy. A weekly follow-up for evaluation of food intake, pain and grading of mucositis was performed. In order to confirm the absence of Candida -related mucositis in patients who developed mucositis, it was performed exfoliative cytology stained with Periodic Acid Schiff and Candifast® kit for biochemical Candida spp identification. Twenty patients did not develop mucositis, two patients developed grade 1 mucositis and two patients developed grade 2 mucositis. None of the patients discontinued food intake and no pain was observed during the study. Candidosis was not detected in any patient. Mucoadhesive propolis gel could be considered as a potential topical medication for preventing radiation-induced oral mucositis. Phase III study with larger number of patients and comparing with market product will be made for confirmation of these results.
