abstract = {Objective: To descript the incidence and mortality rates of oral cancer among Chinese population in 2011, and provide valuable data for oral cancer prevention and research.
Methods: Data from 177 population-based cancer registries distributed in 28 provinces were accepted for this study after evaluation based on quality control criteria, covering a total of 175,310,169 populations and accounting for 13.01% of the overall national population in 2011. Incidence and mortality rates were calculated by area, gender and age groups. The numbers of new cases and deaths were estimated using the 5-year age-specific cancer incidence/mortality rates and the corresponding populations. The Chinese population in 2000 and World Segi’s population were used for age-standardized rates.
Results: The estimate of new cases diagnosed with oral cancer was 39,450 including 26,160 males and 13,290 females. The overall crude incidence rate for oral cancer was 2.93/100,000. The age-standardized rates by China (ASRCN) population and by World population (ASRwld) were 2.22/100,000 and 2.17/100,000, respectively. Among subjects aged 0-74 years, the cumulative incidence rate was 0.25%. The estimated number of oral cancer deaths of China in 2011 was 16,933, including 11,794 males and 5,139 females. The overall crude mortality rate was 1.26/100,000, accounting for 0.80% of all cancer deaths. The ASRCN and ASRwld for mortality were 0.90/100,000 and 0.89/100,000, respectively. Among subjects aged 0-74 years, the cumulative mortality rate was 0.10%. The incidence and mortality rates of oral cancer were much higher in males and urban areas than in females and rural areas. In addition, the incidence and mortality rates were increased by the raising of ages.
Conclusions: Results in the study may have important roles for oral cancer prevention and research. Although oral cancer burden of China is not high, we must pay attention to this malignancy as well. In addition, further researches need to be done for primary and secondary prevention research of oral cancer, especially for the high risk population.},
