Liver cancer incidence and mortality in China, 2009

Abstract

Liver cancer is a common cancer and a leading cause of cancer deaths in China. To aid the government in establishing a control plan for this disease, we provided real-time surveillance information by analyzing liver cancer incidence and mortality in China in 2009 reported by the National Central Cancer Registry. Liver cancer incidence and cases of death were retrieved from the national database using the ICD-10 topography code "C22". Crude incidence and mortality were calculated and stratified by sex, age, and location (urban/rural). China's population in 1982 and Segi (world) population structures were used for age-standardized rates. In cancer registration areas in 2009, the crude incidence of liver cancer was 28.71/100,000, making it the fourth most common cancer in China, third most common in males, and fifth most common in females. The crude mortality of liver cancer was 26.04/100,000, making it the second leading cause of cancer death in China and urban areas and the third leading cause in rural areas. Incidence and mortality were higher in males than in females and were higher in rural areas than in urban areas. The age-specific incidence and mortality were relatively low among age groups under 30 years but dramatically increased and peaked in the 80-84 years old group. These findings confirm that liver cancer is a common and fatal cancer in China. Primary and secondary prevention such as health education, hepatitis B virus vaccination, and early detection should be carried out both in males and females, in urban and rural areas.

Figure 1.. Age-specific incidence of liver cancer in males and females in urban and rural areas in 2009.

The age-specific incidence kept increasing with the age increase and reached at peak in the 80–84 years old group. Incidences in rural areas were higher than those in urban areas and incidences in males were higher than those in females in any age group.

Figure 2.. Age-specific mortality of liver cancer in males and females in urban and rural areas in 2009.

The age-specific mortality kept increasing with the age increase and reached at peak in the 80–84 years old group except for urban females. Mortalities in rural areas were higher than those in urban areas and mortalities in males were higher than those in females in any age group.
