Epidemiological features of the lip cancers and it’s relation with smoking

Abstract

Abstract. To evaluate the epidemiological features of thepatients with lip cancer and the relationship between these features andsmoking. The relationship between epidemiological features, localization of thelesions, histopathological type and smoking was evaluated in 92 patients inthis study. The number of the patients with lip cancers was average 5.41 peryear and the 80% of the cases were male. The average age was 62.1. When theaverage age was compared with gender, the females were meaningfully older thanmales (p<0.05). It wasseen that the patients who smokes were younger than the patients who do not (p<0.05). It was seen that a large number of thepatients (57.6%) were the farmers who work in the open air and they weremeaningfully younger than other professional groups (p<0.05). A large number of the lesions weresquamous cell carcinoma (SCC) (88%). While 86% of the lesions in the patientswith SCC were localized on the lower lip, 70% of the lesions in the patientswith basal cell cancer were localized on the upper lip. There was nostatistical difference in terms of smoking and histopathological types(p>0.05). Lip cancers do not reflect the characteristics of the oral cavitytumors because of the differences in behavioral patterns and while the exposureto ultraviolet sun lights has an important role in the ethiology, it wasevaluated that smoking had a little contribution to the tumor development.  Key words: Lipcancer, epidemiology, ultraviolet, smoking
