2.2　数据质量控制及最终纳入数据

2.2　Data quality control and qualified data

国家癌症中心根据《中国肿瘤登记工作指导手册（2016）》，参照国际癌症研究机构（IARC）/国际癌症登记协会（IACR）、《五大洲癌症发病率》第11卷对肿瘤登记质量的有关要求，从数据可比性、有效性和完整性等方面制定中国肿瘤登记年报数据纳入排除标准。依据标准对2018年肿瘤登记数据进行质量控制，同时充分考虑区域覆盖面，本年报最终纳入700个登记处合格数据作为本年报数据。

全国700个肿瘤登记处2018年覆盖人口523160249人（男性265 488 549人，女性257 671 700人），占2018年中国总人口（1 405 410 000）的37.22%。其中城市地区肿瘤登记处267个，覆盖人口236 047 481人，占入选年报中国肿瘤登记地区人口数的45.12%；农村地区肿瘤登记处433个，覆盖人口287 112 768人，占54.88%。

According to Chinese guideline cancer registration（2016）and the standards of International Agency for Research on Cancer/International Association of Cancer Registries（IARC/IACR）on Cancer Incidence in Five Continents，Vol. Ⅺ，we have published a national criterion on data quality for Chinese cancer registration data from aspects of comparability，completeness and validity.We applied strict quality control on data and consider the wide coverage of different geographic areas in China.A total of 700 cancer registries were included in the present China Cancer Registry Annual Report.

The 700 cancer registries covered a total of 523 160 249 population（265 488 549 males，257 671 700 females），accounting for 37.49% of the national population in 2018.Especially，there were 267 urban cancer registries covering 236 047 481 population（45.12%）and 433 rural cancer registries with population coverage of 287 112 768（54.88%）.

The present annual report summarized data of the cancer incidence，mortality and demography through 700 cancer registration sites in 2018.We reported the quality control indicators including mortality incidence rate ratio（M/I），percentage of morphological verification（MV%），percentage of death certificate only（DCO%），et al，overall and by registration site.We reported data of new cases and deaths of all cancers and by site，including crude incidence，mortality，age-standardized rate（ASR）of China population in 2000，ASR of Segi′s world population，cumulative rates，age and sex-specific rates.Moreover，we presented detailed distribution of subsite and morphology for some cancers.We compared cancer incidence and mortality rates by urban and rural areas，three geographic areas（eastern areas，central areas and western areas），the seven administrative districts（North China，Northeast China，East China，Central China，South China，Southwest China and Northwest China），and 31 provinces（autonomous regions and municipalities）and Xinjiang Production and Construction Corps（not including Hongkong Tebiexingzhengqu，Macau Tebiexingzhengqu and Taiwan Sheng）.
