To describe some epidemiological characteristics of malignant oral cancers in a population of the Oncology Portuguese Institute of Porto (IPO-PORTO).MethodsAfter consulting databases of the IPO-PORTO database, we selected all patients diagnosed with oral cancer (C00 to C06) between 1 January 2004 and 31 December 2009, with histological confirmation. Data were analyzed according district of residence, gender, age, topographic location of the tumor, histological type, degree of differentiation, and stage (TNM).ResultsDuring this retrospective descriptive study, 1041cases were reported in both genders. Men were more affected than women in a 3:1 proportion. The number of diagnosed oral carcinoma cases increased in the 5th decade of age (19.69% ± 2.42%) and progressively decrease after the 7th (18.35% ± 2.35%). The most affected region was the tongue (C01 + C02) (43.51% ± 3.01%), followed by the floor of the mouth (C04) (17.48% ± 2.31%). The most prevalent histological entity was squamous cell carcinoma (93.37% ± 10.90%) in grade I (44.20% ± 5.86%). Regarding TNM stages, the most frequent was stage IV (42.00% ± 3.89%).ConclusionThe epidemiological profile of oral malignant neoplasms found in our study is in accordance with the existing literature. More epidemiological studies, as well as awareness and prevention programs, should be conducted in this area in Portugal.
