||BACKGROUND: This study aimed to analyze the trend in the number of hospitalized cases of oral cancer in Brazil, according to the coverage of oral health services in public health system, and also investigate the influence of healthcare and clinical characteristics on the severity of oral cancer cases. MATERIAL AND METHODS: This retrospective study considered the period between 2009 and 2017. Data from the Hospital Registry of Cancer from the National Cancer Institute were used, considering the primary locations C00 to C06. Detailed information including sex, age, alcohol and tobacco use, year of first consultation, and the clinical stage of the cases were also collected. The frequency of hospitalized cases was correlated with the coverage of Primary Care Oral Health Teams (ESB) and the number of Dental Specialty Centers (CEO). It was also estimated the chance of advanced oral cancer cases, according to healthcare and clinical characteristics. Data were analyzed using Tweedie's multiple regression and multiple binary logistic regression (Alpha < 0.05). RESULTS: There was an increasing trend in the number of hospitalized cases of oral cancer in Brazil between 2009 and 2017 (B = 0.043, p < 0.001, PR = 1.044). The increase in ESB coverage was associated with small increase in the number of hospitalized cases of oral cancer (B = 0.001, p = 0.003, PR = 1.001). The increase in the number of CEO was associated with decrease in the number of hospitalized cases of oral cancer (B = -0.085, p < 0.001, PR = 0.918). The increase of ESB (OR = 0.998) and CEO (OR = 0.974) contributed for reducing the number of stage IV cases, whilst the history of alcohol and tobacco use (OR = 1.574) was associated with an increase in the number of stage IV cases. CONCLUSIONS: Although an increasing trend was detected, the expansion of the public health system reduced the number of hospitalized cases and the frequency of advanced oral cancer cases in Brazil|
