| Outline of Final Research Achievements |
Severe oral mucositis often occurs in patients who undergo radiotherapy (RT) or chemo-radiotherapy (CRT) to the oral region. The aim to the study is to investigate the effectiveness of oral management on development of grade 3 oral mucositis in patients with oral cancer undergoing RT by a multicenter, randomized clinical trial. A total of 88 patients were enrolled in the study, and randomly divided into the intervention and the control group. Patients in the intervention group received spacer, administration of pilocarpine and dexamethasone ointment. Various demographic, tumor-related, and treatment-related factors were examined. The primary endpoint is development of grade 3 oral mucositis. Oral care intervention did not prevent grade 3 oral mucositis in all 88 patients. However, when patients were divided into RT and CCRT groups, the occurrence rate of grade 3 mucositis was significantly lower in the oral care group than that in the control group in patients undergoing RT alone.
