[Purpose] To investigate the cancer incidence and mortality in cancer registration areas in 2008.[Methods] After checking and evaluating the cancer registry data in 2008 from 56 cancer registries,of them 41 registries’ data were selected for this analysis.We classified cancer registries into two categories: urban and rural.Incidence and mortality rates,age-specific rates,age-standardized rates,proportions,cumulative rates were calculated.[Results] The population coverage of all 41 registries were 66 138 784(52 158 495 in urban areas and 13 980 289 in rural areas).The total cancer incident cases and deaths were 197 833 and 122 136,respectively with mortality to incidence rate ratio of 0.62.The morphological verified rate was 69.33% and 2.23% of cases were identified by death certificate only.The crude cancer incidence in registration areas was 299.12/10 5(330.16/10 5 in male and 267.56/10 5 in female) and age-standardized incidence rates by Chinese standard population(ASIRC) and by world standard population(ASIRW) were 148.75/10 5 and 194.99/10 5,respectively with cumulative incidence rate(0～74 age years old) of 22.27%.Both of crude and adjusted incidence rates in urban areas were higher than that in rural areas.The crude cancer mortality was 184.67/10 5(228.14/10 5 in male,140.48/10 5 in female),and age-standardized mortality rates by Chinese standard population(ASMRC) and by world population were 84.36/10 5 and 114.32/10 5 respectively with cumulative mortality rate(0～74 age years old) of 12.89%.Age-adjusted mortality rates in urban areas were lower than that in rural areas.The top ten commonest cancer types were lung,stomach,colorectum,liver,esophagus,pancreas,brain,lymphoma,breast and cervix,accounting for 75% of all cancer incidence in registration areas.Lung cancer was the leading cause of cancer death,followed by gastric cancer,liver cancer,esophageal cancer,colorectum cancer and pancreas cancer.The mortality of top ten cancers accounted for 80% of all cancer deaths.The cancer spectrum was quite different in different locations and sexes.In rural areas,cancers from digestive system were still common,such as esophageal cancer,gastric cancer and liver cancer.However,common cancers,such as lung cancer,colorectal cancer and breast cancer were the main cancer types in urban areas.[Conclusions] Lung cancer,gastric cancer,colon and rectum cancer,liver cancer and esophageal cancer are the major cancer burden in China,which should be focused on for national cancer prevention and control program in the future.Different cancer control strategies should be carried out due to the different cancer spectrum in urban and rural areas.
