Background and objective At present, population-based cancer registries were not well established and epidemiologic data for cancer were limited at the province level in China. Using the available mortality data for cancer, estimation model of lung cancer was established to provide the mortality profile for the population in 31 provincial regions in China in 2008. Methods Based on the population coverage and accuracy of the available mortality for provinces, the methods used to produce mortality estimates fall into 1 of the 3 categories: data were used directly; a model was developed to calculate annual change of mortality rate based on historical and current data; relative frequency data combining with mortality for all sites were used to estimate site-specific mortality. Results The total estimated deaths of lung cancer in 2008 were 493,348 (338,346 in males and 155,002 in females) in the whole country. The age-standardized rates were highest in Jilin (52.29 per 100,000 in males and 24.68 per 100,000 in females), and the lowest rates were in Tianjin (24.12 per 100,000 in males) and Chongqing (8.72 per 100,000 in females). Conclusion The models for lung cancer mortality at the province level have been established and the data will provide valuable scientific reference for describing the epidemic of lung cancer as well as estimating other site-specific cancer mortality in China.

Objective: To evaluate the trend of cervical cancer incidence and mortality rates during 1989-2008 in Chinese women, so as to inform the development of relevant policies and strategies in China. Methods: The incidence and mortality rates of cervical cancer during 1989-2008 in urban and rural areas were calculated based on the data from the National Cancer Registry Database. Age-standardized rates were calculated using the Chinese population of 1982 and World Segi's population of 1985. Joinpoint regression analysis was performed to obtain annual percentage changes (APC) so as to assess the trend of incidence and mortality rates over the period from 1989 to 2008. Results: The crude incidence rate of cervical cancer in Chinese women increased from 3.06/10 5 in 1989-1990 to 11.87/105 in 2007-2008 (from 4.96/105 to 11.98/105 in urban registration areas and from 2.39/105 to 11.77/105 in rural registration areas). The crude mortality rate slightly increased from 2.19/105 in 1989-1990 to 3.20/105 in 2007-2008 (from 3.21/105 to 2.56/10 5 in urban registration areas and from 1.82/105 to 3.75/105 in rural registration areas). Generally, the upward trends of crude incidence rates were shown over the year 1989-2008, with an APC of 14.4% after 1997 in urban areas and 22.5% after 1999 in rural areas. After age standardization of world population, the APC of incidence rates in recent decade in urban areas remained stable, and the one in rural areas slightly decreased. Although the overall crude and world age-standardized mortality rates had no significant changes during 1989-2008, the crude mortality rates increased by 8.1% annually after 1999. The upward trends were also shown for crude and world age-standardized mortality rates in urban areas after 2001 with an APC of 7.3%. The crude mortality rates in rural areas increased by 3.9% annually during 1989-2008, but no significant change was found after age standardization. Conclusions: Over the last decade, the cervical cancer incidence and mortality rates ascended by year in China. It is particularly urgent to establish a comprehensive prevention and control system that combines cervical cancer screening and human papillomavirus vaccination, so as to reduce the burden of cervical cancer in Chinese women.

Objective: Cancer is one of the leading causes of death in China. The study aimed to examine the temporal trend of cancer mortality rate during 1989-2008 in urban and rural areas of China. Methods: The mortality data of all cancers from 1989 to 2008 from National Cancer Registry database were sorted and checked. Age standardized mortality rates were calculated by the direct methods using the China population of 1982 and World Segi's population. Joinpoint regression was performed to obtain the annual percentage changes (APC) in mortality rates. The top ten cancer sites were calculated and analyzed. The mortality rates were compared with statistics of the United States. Results: From 1989 to 2008, the trend of crude cancer mortality increased with an annual percentage change (APC) of 1.0%. After age standardization, the mortality rate was significantly decreased, with an APC of -1.2%. In urban areas, lung cancer was the most common cancer of death, whereas in rural areas, stomach cancer and esophageal cancer remained top cancers of death. Especially, in both urban and rural areas, the mortality of lung cancer was on increase. The mortality rates of stomach and esophageal cancers showed a decrease in urban areas. Compared with the cancer mortality rates of the United States, the Chinese cancer mortality rate in males remained highest. The decreasing trend of cancer mortality in females of China was less obvious than that of the United States. Conclusions: The crude mortality rates of cancer in China show an increase whereas the age standardized mortality raters has declined between 1989 and 2008. Cancer is still a major public health issue threatening people's life in China. Effective intervention for cancer control and prevention is needed in the future.

Objective: Nationwide cancer incidence data were used to analyze the trends of cancer incidence in China in order to provide basic information for making cancer control strategy. Methods: We retrieved and re-sorted valid cancer incidence data from the National Central Cancer Registry Database over the 20 year-period 1989-2008. Crude incidence rate and age-standardized incidence rate were calculated for analysis. Annual percent changes in incidence for all cancers combined were estimated using Joinpoint software. Results: The cancer incidence rate in cancer registration areas was increased from 184.81/10 5 in 1989 to 286.69/105 in 2008 (from 209.33/10 5 to 307.04/105 in urban and from 176.10/105 to 269.57/105 in rural areas). Uptrends of crude cancer incidence were shown in both male and female in urban and rural areas over the 20 year-period. After standardized by age, overall incidence rate kept stable with 0.5% annual increase in urban and no change in rural areas. Since 2000, the cancer incidences in both sexes and areas were significantly increased. The incidence increased for most major cancers, especially lung cancer, colorectal cancer, female breast cancer and cervical cancer. Conclusions: Over the 20 year-period 1989-2008, cancer incidence of most cancers has been increasing by time. The incidences of gastric cancer, liver cancer and esophageal cancer still keep gradually increasing. The incidences of lung cancer, female breast cancer, colorectal cancer and cervical cancer are markedly going up, so that cancer prevention and control should be enhanced. Cancer registration will play an important role on cancer control in China along with the number of registries increasing and data quality improving.

Objective: To analyze lung cancer epidemiological trends and estimate the lung cancer burden in China. Methods: The age-specific mortality/incidence ratios in different geographical areas and for both sexes for lung cancer were obtained from the National Cancer Registration database in 2004 and 2005. Cancer crude mortality rates were retrieved from the database of the third national death survey from 2004-2005. Age-specific incidence rates of lung cancer were calculated using mortality and mortality/incidence ratios. The annual percent change was estimated with a log regression model using joinpoint software analyzing pooled lung cancer incidence data from 10 cancer registries from 1988 to 2005. Results: The total estimated new lung cancer cases and deaths in 2005 were 536407 and 475768 respectively, the numbers were higher for men than for women, and show an increase of 1.63% annually from 1988 to 2005. However, the trend showed a slowdown of 0.55% after being adjusted for age. Conclusions: Lung cancer is one of the major health issues in China and the burden is getting serious. Aging is the main cause for the increasing incidence and mortality of lung cancer. Effective cancer prevention and control is imperative. Tobacco control especially should be implemented in nationwide. © Tianjin Lung Cancer Institute and Blackwell Publishing Asia Pty. Ltd.

OBJECTIVE: To analyze the changes of male/female and urban/rural incidences and average age of cancer diagnosis over the period 1989-2008 in China.METHODS: All cancer incident cases from 1989 to 2008 in registration areas were retrieved from the National Central Cancer Registry database. Data were stratified by sex (male/female) and area (urban/rural) and age group (19 age groups, including 0, 1-4, 5-9, 5-84 by 5, ≥ 85). Poisson regression was used to analyze the differences in incidence rates between males and females, urban and rural areas with 95% confident intervals and P values adjusted by age. The average age of cancer diagnosis was calculated every year. All trends were analyzed by linear regression.RESULTS: The ratio of male to female cancer incidences was 1.56 in 1989 and 1.35 in 2008. The ratio of urban to rural incidences was 0.89 in 1998 and increased to 0.98 in 2008. The average age of cancer diagnosis was 61.96 years old for men and 60.15 for women in 1989, compared with 64.87 and 61.81 years in 2008, respectively. The disparities in sex and areas have been decreasing in recent 20 years. The cancer patients tend to getting older. These trends were all significant.CONCLUSIONS: The cancer incidences in male/female populations and different areas have apparent disparities over the 1989-2008 period in China. However, the differences are narrowing and the average age is increasing. In the making of an efficient anti-cancer strategy, we should also take consideration of the differences of cancer burden in different population groups in our country.

Background and objective: The aim of this study is to analyze lung cancer epidemiological trend and estimate lung cancer burden in China. Methods: Lung cancer age specific mortality and incidence rate ratios in different areas and sexes were obtained from national cancer registration database in 2004 and 2005. Cancer crude mortalities were retrieved from the database of the third national death survey, 2004-2005. Age specific incidence rates of lung cancer were calculated using mortality and M/I ratios. Annual percent change (APC) was estimated by log regression model using Joint Point software by analyzing pooled lung cancer incidence data from 10 cancer registries from 1988 to 2005. Results: The total estimated new cases and deaths of lung cancer in 2005 were 536 407 and 475 768 which were higher in male than in female. There was 1.63% increase of lung cancer incidence per year from 1988 to 2005, however, the trend showed a slowdown by 0.55% annually after adjusted by age. Conclusion Lung cancer is one of major health issues in China and the burden is getting serious. Ageing population is main cause for increasing incidence and mortality of lung cancer. Effective cancer prevention and control is imperative. Especially, tobacco control should be carried out in statewide.
