Prevalência de queilite actínica e câncer de lábio na população de Governador Valadares - MG

Abstract

Introduction: Actinic cheilitis (AC) is considered a potentially malignant oral disorder that can progress to squamous cell carcinoma of the lip. It affects more male patients and fair-skinned individuals who engage in outdoor activities. Objective: This study was aimed at characterizing the profile of patients affected by AC in the city of Governador Valadares, Minas Gerais, Brazil. Methods: Medical records of 301 patients treated at the Stomatology Service of the Federal University of Juiz de Fora, Governador Valadares Campus in 2022 and 2023 were accessed. Results: Of the total sample, 4,65% of patients (14 patients) were diagnosed with AC, indicating a low local prevalence of AC. The profile of patients diagnosed with AC at the site was in accordance with that reported in the literature. The patients diagnosed included 87,5% male patients with fair skin, with a mean age of 64,5 years, and the majority engaged in outdoor activities. Of the patients, 37,5% reported tobacco use and 14,2% showed progression to squamous cell carcinoma of the lip. Conclusion:The present study reflects the profile of a local population, with a low prevalence of AC and lip cancer. Despite the population being located in a city with a tropical climate, it is predominantly made up of people with brown skin, which justifies the study's findings. More studies are needed to establish the real prevalence of AC in the population of Governador Valadares.
