PG - E815-9 LID - 10.1002/hed.24106 [doi] AB - BACKGROUND: The purpose of this study was to assess predictors of mucositis in oropharyngeal and oral cavity cancer after definitive or adjuvant volumetric modulated arc radiotherapy (VMAT) +/- chemotherapy. METHODS: Fifty patients were evaluated. Statistical analysis was performed for the following parameters as potential predictors of mucositis >/= G2: total oral mucosa and oral mucosa minus target high-low radiation dose regions (planning target volumes [PTVs]), mean dose (Dmean ), maximum dose (Dmax ), chemotherapy, weight loss, and dysphagia. RESULTS: Mucositis >/= G2 was found to be statistically related to chemotherapy, weight loss, dysphagia >/= G2, total oral mucosa Dmean >/=50 Gy and Dmax >/=65 Gy, V45 Gy >40%, V50 Gy >30%, and V55 Gy >20% of the oral mucosa minus target PTVs. A ratio between total oral mucosa and oral mucosa minus target PTVs >2.5 is related to G3 mucositis (p = .03). CONCLUSION: New parameters were found as predictors of moderate-severe mucositis.
