Conditional relative survival of oral cavity cancer: Based on Korean Central Cancer Registry

There were an estimated 300,383 global cases of lip and oral cavity cancer in 2012, with more than half of the patients located in Asia [1]. In Korea, the incidence of oral cavity cancer has been dynamically changing, with an increasing incidence among women, as well as an increasing incidence of tongue cancer among young adults [2]. Although oral cavity cancer does not account for a large proportion of all Korean cancer cases, the cancer is associated with significant effects on physiological function, facial esthetics, and survival.
