Oral cavity cancer incidence and mortality in China, 2010.
OBJECTIVE
To analyze the incidence and mortality of oral cavity cancer in the cancer registration areas of China in 2010.


METHODS
Until June 1, 2013, 219 population-based cancer registries submitted the data of 2010 to the National Central Cancer Registry of China covering about 207,229,403 population, and 120 cancer registries were selected after the quality evaluation for this analysis. Oral cavity cancer cases were selected from the database according to the International Classification of Diseases-10 coded as "C00-C10, C11-C12." We calculated the crude incidence and mortality rates of oral cavity cancer by sex, age, and location (urban/rural). The China population in 2000 and Segi's population were used as standardized populations for the calculation of age standardized rates.


RESULTS
In 2010, it was estimated that there were 34,319 new cases diagnosed as oral cavity cancer in China, including 23,096 males and 11,223 females. The crude incidence rate of oral cavity cancer was 2.61/100,000 in 2010, accounting for 1.11% of overall new cancer cases, ranked the 20th in all cancer sites. The age standardized by China population (ASRcn) and by world population (ASRwld) were 2.06/100,000 and 2.02/100,000, respectively. Cumulative rate (0-74 years old) and truncated age standardized rate (35-64 years old) were 0.23% and 3.82/100 000, respectively. In 2010, it was estimated that there were 14,652 cases died in oral cavity cancer in China, including 10,363 males and 4289 females. The crude mortality rate of oral cavity cancer was 1.11/100,000 in 2010, accounting for 0.75% of overall cancer deaths, ranked the 20th in all cancer sites. The ASRcn and ASRwld were 0.86/100,000 and 0.85/100,000, respectively. Cumulative rate and truncated age standardized rates were 0.10% and 1.30/100,000, respectively.


CONCLUSIONS
Both the incidence and mortality of oral cavity cancer in China were still low in 2010. Primary prevention such as smoking control, reducing alcohol consumption, changing the habit of chewing betel nut, and chemical prevention should be enhanced in the general population.
