Epidemiology of uterine corpus cancer in some cancer registering areas of China from 2003-2007 / 中华妇产科杂志

ABSTRACT

Objective To analyze corpus uteri epidemiology in selected cancer registering areas of China during 2003-2007,and to provide scientific information for its prevention and control in China.Methods The incident and mortality data of corpus uteri cancer in 32 cancer registering areas of China with better quality during 2003-2007,which were selected according to the criteria of and provided by National Center for Cancer Registration,were analyzed.Results There were 8850 new cases and 1559 death cases of corpus uteri cancer,which accounted for 2.96％ ( 8 850/299 306 ) of all female new cancer cases and 0.94％ ( 1 559/166 305) of all female cancer death cases,respectively.Corpus uteri cancer was the 9th most common cancer for all new female cancer cases which world age adjusted incidence rates was 5.04/105,and 19th most common cancer for all female cancer death cases which world age adjusted mortality rate was 0.83/105 in 32 selected cancer registering areas of China during 2003-2007.Zhongshan city,Guangzhou city in Guangdong province and Beijing were the areas with the highest incidence rates in which were 14.51/105,8.51/105 and 6.69/105,respectively.Zhongshan city in Guangdong province,Dafeng city in Jiangsu province and Feicheng city in Shandong province were the areas with the highest mortality rates,in which were 4.03/105,3.19/10s and 1.65/105 respectively during 2003-2007.There were increasing trends for its incidence rates in above 32 areas during 2003-2007,its world age adjusted incidence rates increased from 3.94/105 in 2003 to 5.56/105 in 2007 ( P =0.026 ),while its urban world age adjusted incidence rates increased from 4.57/105 in 2003 to 6.18/105 in 2007 (P =0.038),and rural rates increased from 1.74/105 in 2003 to 3.01/105 in 2007 ( P =0.013 ),and the results showed that urban areas obviously higher than rural areas ( P ＜ 0.01 ).Although there was a slow increasing trend for its world age adjusted mortality rates in above 32 areas during 2003-2007 which increased from 0.64/105 in 2003 to 0.87/105 in 2007 ( P =0.214 ),and from 0.66/105 in 2003 to 0.88/105 in 2007 in urban areas ( P =0.340 ),and from 0.57/105 in 2003 to 0.83/105 in 2007 in rural areas( P =0.070),while increasing trends without statistical significance.But mortality rates in urban areas were obviously higher than those of rural areas (P ＜0.01 ).Conclusions Although the world standardized incidence and mortality rates of corpus uteri cancer were at low level worldwide,there were increasing trends for its incidence rates during 2003-2007 in the 32 selected cancer registering areas of China.Moreover,its incidence and mortality rates were at high level worldwide in some areas such as Zhongshan city of Guangdong province and Dafeng city of Jiangsu province during the period,in which suggested that its prevention and control should be enhanced.
