[Heavy] 2015 China Cancer Statistics Report Released (Full Text)

As morbidity and mortality increase, cancer is becoming the leading cause of death in China and an important public health problem. Because of China's large population (1.37 billion people), previous national morbidity and mortality assessments were limited to small samples in the 1990s or based on specific years. Now through high-quality data from the National Central Cancer Registry, the authors analyzed 72 population-based cancer registrations (2009-2011), representing 6.5% of the population, to estimate the number of new cases and cancer deaths in 2015. Trend analysis (2000-2011) used data from 22 registries. The results indicate that 4292,000 new cancer cases and 2814,000 cancer deaths are expected in 2015, with the highest morbidity and mortality rates for lung cancer. The incidence and mortality of gastric cancer, esophageal cancer and liver cancer are also high. Combining the morbidity and mortality of all cancers, the age-standardized data of rural residents is higher than that of urban residents (incidence rate 213.6 people / 100,000 people vs 191.5 people / 100,000 people; mortality rate 149 people / 100,000 people) Vs109.5 people / 100,000 people). Combining all cancers, between 2000 and 2011, the incidence of men remained stable (+0.2% per year; P=.1), and the incidence of women increased significantly (+2.2% per year; P<.05) .

In contrast, mortality has been declining since 2006, regardless of male (-1.4% per year; P < .05) or female (-1.1% per year; P < .05).

Many cancers within the assessment can reduce morbidity and mortality by reducing cancer risk factors and improving the efficiency of clinical care services, especially for rural populations and vulnerable groups.

1 Introduction

Cancer morbidity and mortality in China have been rising, and since 2010 it has become the leading cause of death and has become a major public health problem in China. A significant portion of this increasing pressure can be attributed to population growth and ageing as well as changes in sociodemographic statistics. Although there were previous national morbidity assessments, those assessments could only represent a small population (less than 2%) or only a specific year. This has an impact on the uncertainty and representation of the assessment and can potentially influence the development of cancer control policies. Because the previous China Cancer Prevention and Control Project (2004-2010) was released 10 years ago, a more complex depiction of the scale and profile of cancer across China and everywhere will provide clearer priorities for Policy and planning for cancer spectrum provides a reference to alleviate the country's cancer burden.

The study assessed cancer morbidity, mortality, and survival across the country; morbidity and mortality in several major cancer subregions; time trends in several major cancers and guidance on how to provide information on cancer prevention in China .

2 data sources and methods

2.1 China Cancer Registry

The National Cancer Registry (NCCR) was established in 2002 to collect, evaluate, and publish cancer data in China. Cancer diagnosis will be reported to the local cancer registry, which has multiple sources, including local hospitals and community health centers, as well as urban residents' basic medical insurance and NCMS. Since 2002, the implementation of the standard registration regulations has greatly improved the quality of cancer data. In 2008, the Ministry of Health implemented the National Cancer Registry through the central financial system. Since then, the number of population-based registrations has increased from 54 in 2008 (population coverage of 110 million people) to 308 in 2014 (population coverage of 300 million people).

Not all registrations currently have sufficient high-quality data to report. Data submitted by each local registry will be reviewed by the NCCR and the International Agency for Research on Cancer/International Association for the Registration of Cancer (IARC/IACR). Quality assessment includes, but is not limited to, the proportion of morphological identification (MV%), the proportion of cancer cases with death certificates (DCO%), mortality/morbidity ratio (M/I), and the proportion of uncertified cancer ( UB%), the percentage of the primary cancer site that is not clear or located (CPU%). Only data that meets these requirements will be used in the analysis. The specific quality classification of the registration data can be found in previous publications (Table 1). Data classification as A or B was considered acceptable in this study. The percentage of available registration data available varies from year to year, from 69.2% in 2009 (72 out of 104), to 66.2% in 2010 (145 out of 219), and 75.6 in 2011. % (177 of 234 are available). We used data from 72 registries that were available for three years.
