Abstract

Mouth and oropharyngeal cancers (CAs) are considered to be global public health problems, with high psychosocial impacts and high costs. Developing an epidemiological profile and examining the survival rate among patients with CAs of the mouth and oropharynx are important for the development of public policy. Therefore, this retrospective study aimed to evaluate mouth and oropharyngeal CA patients treated at the Municipal Hospital Salgado Filho in Rio de Janeiro, Brazil between 2007 and 2017. Patient data regarding gender, age, ethnicity, diagnosis, anatomical site affected by the tumor, and habits were obtained from patient records and reports, and data regarding the deaths of patients were obtained from records and the Mortality Information System. After tabulation, data were descriptively analyzed using the Kaplan-Meier survival curve, and the log-rank test was used for the comparison of variables. Survival rates at 5 and 8 years were 71.1% and 48.8%, respectively. There were no significant differences among survival rates according to age, sex, ethnicity, or the anatomical location of tumors. The survival rates among mouth and oropharyngeal CA patients in this study were comparable with the results reported in developed countries.
