DEMOGRAPHIC CHARACTERISTICS OF PATIENTS WITH ACTINIC CHEILITIS IN LABIAL MUCOSA DIAGNOSED IN 2 ONCOLOGIC CARE CENTERS

Objective The aim of this study was to characterize the demographic profile and evaluate the clinical stage of the cases of actinic cheilitis diagnosed in 2 oncologic care centers localized in Curitiba/PR and Joacaba/SC. Study Design The medical records of patients with potentially malignant lesions and squamous cell carcinoma (SCC) were analyzed. We evaluated the age, sex, occupation, tumor staging, and relation with habits (smoking, and alcohol) during the period from 2012 to 2016. Results Of the 160 medicals records evaluated, 70.62% were male, mean age 60 years, presenting high sun exposure rate (65%), and 40% of patients reported high-risk occupational occupation. The smoking habit was reported by 44.38% of patients and the alcohol consumption by 21.87%. In 12.5% of actinic cheilitis cases we observed the evolution to squamous cell carcinoma. Conclusions The use of sunscreen was effective in the prevention of squamous cell carcinoma in lip, and the absent of follow-up care in patients with actinic cheilitis can influence the rates of malignization to squamous cell carcinoma, because the patients does not change the habits and the dentist cannot identify earlier the malignization of actinic cheilitis.
