An increase in the incidence of oral squamous cell carcinomas (OSCC) in patients younger than 45 years old has been demonstrated worldwide. However, the scenario of young patients with oral cancer is still controversial, which limits the comprehension of its pathogenesis, biological behavior of tumors and patients prognosis. Hence, there is a lack of well-defined cancer treatment protocols in this context. Similarly, the impact of age in the risk for developing radiation-related oral toxicities is also unknown. Objectives: Determine the incidence and the severity of oral toxicities associated with radiotherapy (RT) in young patients with OSCC. Material and methods: Observational clinical study, retrospective, controlled, involving patients diagnosed with OSCC who completed RT and received dental support from the Service of Dental Oncologic at the São Paulo State Cancer Institute (ICESP), from December 2013 to December 2016. The patients will be distributed into two groups: young (<45 years old, n=20) and elderly (>60 years old, n=20) and paired according to tumor location, clinical stage of disease and cancer treatment modality. Demographic information and clinicopathological data concerning acute oral toxicities will be collected relative to the 7th, 21st and 35th days of RT, with emphasis to the following clinical outcomes: oral mucositis, xerostomia, trismus, dysgeusia, dysphagia, pain, opportunistic infections and radiodermitis, according to the Common Terminology Criteria for Adverse Events version 4.0 and the World Health Organization (1979). Expected Results: Contribute to the better understanding of the problematic of side effects of cancer treatment in young patients with oral cancer.
