Research progress on liver cancer epidemiology

The newest researches and data about liver cancer epidemiology available now were collected, and the current status and progress on the research of liver cancer epidemiology were systematically reviewed. It was found that liver cancer was still one of the common cancers, the top 7 and 2 incident cancer, respectively in the world and China in 2012. With very poor prognosis and low survival, it posed big threat to people`s life and health. Its incidence was high in underdeveloped areas, basically with the same geographical distribution for its mortality, but a little difference for its prevalence. Its male incidence, mortality, and prevalence were much higher than the female rates. Recently, its incidence and mortality remained stable in the world, but decreased slightly for its incidence, mortality, and prevalence, and rose slightly for its survival in China. The DALYs of liver cancer accounted for 54.6% of the DALYs caused by all cancers in China in 2016, and China was the country with the highest DALYs caused by liver cancer globally. It suggested that the control and prevention of liver cancer should be enhanced.
