Abstract
Objective To describe the profile of young Brazilian adults with squamous cell carcinoma (SCC) in the oral cavity and its relationship with death between 1985 and 2017. Study Design Cross-sectional hospital-based study with individuals aged 19 to 40 diagnosed with SCC from Brazilian cancer hospital records. Data were analyzed by the prevalence ratio, 95% CI, and logistic regression. Results 1761 cases of SCC in young adults during the study period were found. The largest number of cases were concentrated in the age group 31 to 40 years (79.80%), men (71.90%), White (50.20%), from the southeast region (36.40%), without a partner (58%), and with elementary schooling (63.40%). Regarding risk factors, 61.60% were smokers, 56.70% were drinkers, 18.50% were agricultural/aquaculture professionals, and 40.70% reported a family history of cancer. The most frequent localization was on the tongue (42.40%), and 25.50% of patients died. When the main association between death and cancer location on the tongue was adjusted, the odds ratio for death increased to 7.832 (95% CI, 2.625-23.374, P < .0001). Conclusions Greater attention to SCC is needed in this population to reduce the incidence and lethality of this public health problem.
