To estimate the cancer incidence and mortality in China in 2004 - 2005 based on available resources.
The cancer mortality and incidence ratios were obtained on the basis of national cancer registration database in 2003 and 2004 adjusted by age and area. The crude cancer mortalities were retrieved from the database of the third national death survey 2004-2005. Incidence rates of specified cancer types were calculated using mortality and M/I ratios.
The total estimated cancer incidence and mortality per year in 2004 - 2005 were 2 596 112 new cases and 1 798 147 deaths, both were higher in males than in females. There were 1 337 227 new cases and 841 860 deaths in urban areas compared with 1 258 885 new cases and 956 287 deaths in rural areas. Cancers of the lung, stomach, liver, esophagus and colorectum/anus were the commonest cancers in China with 483 040, 428 380, 370 236, 236 589 and 197 873 new cases, respectively. Those five cancers were leading causes of cancer death with a number of 420 411, 339 308, 318 756, 190 233 and 101 684, respectively.
Cancer burden in China is getting more and more serious. It is imperative to enhance effective cancer prevention and control in China.
基于现有资源估算2004 - 2005年中国的癌症发病率和死亡率。
依据2003年和2004年经年龄和地区调整的全国癌症登记数据库获得癌症死亡率和发病率比值。从2004 - 2005年第三次全国死因调查数据库中检索粗癌症死亡率。使用死亡率和M/I比值计算特定癌症类型的发病率。
2004 - 2005年每年估计的癌症总发病率和死亡率分别为2596112例新发病例和1798147例死亡，男性均高于女性。城市地区有1337227例新发病例和841860例死亡，农村地区有1258885例新发病例和956287例死亡。肺癌、胃癌、肝癌、食管癌和结直肠癌/肛门癌是中国最常见的癌症，新发病例分别为483040例、428380例、370236例、236589例和197873例。这五种癌症是癌症死亡的主要原因，死亡人数分别为420411例、339308例、318756例、190233例和101684例。
中国的癌症负担日益加重。在中国加强有效的癌症预防和控制势在必行。
