The relationship beetwen tobacco exposure, alcoholabuse and poor dental hygiene and disease developement has been clearly proportional demonstrated. A clear dose-response relationship has been identified with a greater risk being directly proportional to intensity and duraton of exposure. Other possible etiologic agents are being investigated. Prognostic evaluation is based on clinical staging of the tumor, on histologic characteristic of the primary tumor and the lymph nodes. Selection of the therapy depends on multiple factors; three major types of therapeutic modalities are avaible; surgery, radiation and a combination of both surgery and radiation. The lip is the mostcommon site in the cancer of the head and neck. The majority of these lesions occur on the lower lip and males. A principal ethiologic factor is sunexposure and use of tobaco. The prognosis is better, compared to other forms of oral carcinoma. Surgery is the mainstay of therapyRak ustne votline predstavlja približno 6% rakavih obolenj in okoli 30% vseh tumorjev glave in vratu. Pomembni etiološki dejavniki so uporaba tobaka, uživanje alkoholnih pijačin slaba ustna higijena. Tveganje za nastanek boleznije odvisno od trajanja in intenzitete škodljivih dražljajev. Prognoza je odvisna od ocene kliničnega štadija in histoloških značilnosti tumorja in regionalnih bezgavk. Na izbiro zdravljenja vplivajo različni dejavniki, v poštev pa pride kirurško zdravljenje, radioterapija in kombinacija kirurškega zdravljenja in radioterapije. Rak ustnic je najpogostejši tumor v zgornjem aerodigestivnem traktu. Največkrat se pojavi na spodnji ustnici pri moškem. Glavni etiološki dejavnik je izpostavljenost sončni svetlobi in kajenje. Prognoza je na splošno boljša kot pri ostalih karcinomih ustne votline. Kirurgija je glavni način zdravljenjaTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaOnkološki inštitut Ljubljana
