Report of Cancer Incidence and Mortality in China,2011

[Purpose] To estimate the cancer incidence and mortality in China in 2011. [Methods]On basis of the methods and criteria of data quality control made by NCCR,177 registries' data qualified from 234 submitted registries after data clearance and assessment as pooled data. The data was stratified by area(urban/rural),gender,age group and cancer site,incidence and mortality were calculated combined with national population in 2011. Chinese population census in 2000 and Segi's population were used for age-standardized incidence/mortality rates. [Results] All 177 cancer registries(77 in urban and 100 in rural) covered a total of 175 310 169 population(98 341 507 in urban areas and 76 968 662 in rural areas),accounted for 13.01% of whole national population in 2011. The morphology verified cases(MV%) accounted for 70.14%,and 2.44% of incident cases were identified through death certifications only(DCO%) with mortality to incidence ratio(MI ratio) of0.63. It was estimated that new cancer cases and cancer deaths were 3 372 175 and 2 113 048 in2011,respectively. The crude incidence in China was 250.28/105(male 277.77/105,female 221.37/105),age-standardized incidence by Chinese standard population(ASR China) and by world standard population(ASR world) were 186.34/105 and 182.76/105 with the cumulative incidence(0~74 age years old) of 21.20%. The cancer incidence and ASR China were 261.38/105 and 189.89/105 in urban areas, whereas 238.60/105 and 182.10/105 in rural areas,respectively. The crude mortality in China was 156.83/105(male 194.88/105,female 116.81/105),age-standardized mortalities by Chinese standard population(ASR China) and by world standard population(ASR world) were 112.88/105 and 111.82/105 with the cumulative mortality(0~74 age years old) of 12.69%. The crude cancer mortality and ASR China were 154.37/105 and 108.20/105 in urban areas, and 159.42/105and117.97/105 in rural areas,respectively. Cancers of lung cancer,female breast,stomach,liver,colon and rectum,esophagus,cervix,uterus,pancreas and ovary were the most common cancers,accounting for about 75% of all cancer new cases. Lung cancer,liver cancer,gastric cancer,esophageal cancer,colorectal cancer,breast cancer,pancreatic cancer,brain tumor,cervical cancer and leukemia were the leading causes of cancer death,accounted for about 80% of all cancer deaths.[Conclusions] The coverage of cancer registration population had a greater increase than that in the last year. The data quality and representativeness are gradually improved. As the basic work of cancer prevention and control,cancer registry is playing an irreplaceable role. The disease burden of cancer is increasing,the health department has to take effective measures to contain the increased cancer burden in China.
