China faces a disproportionate cancer burden to the population size and is undergoing a transition in the cancer spectrum.We extracted data in five aspects of cancer incidence,mortality,survival,staging distributions,and attribution to risk factors in China,the USA and worldwide from open-source databases.We conducted a comprehensive secondary analysis of cancer profiles in China in the above aspects,and compared cancer statistics between China and the USA.A total of 4,546,400 new cancer cases and 2,992,600 deaths occurred in China in 2020,accounting for 25.1%and 30.2%of global cases,respectively.Lifestyle-related cancers including lung cancer,colorectal cancer,and breast cancer showed an upward trend and have been the leading cancer types in China.41.6%of new cancer cases and 49.3%of cancer deaths occurred in digestive-system cancers in China,and the cancers of esophagus,nasopharynx,liver,and stomach in China accounted for over 40%of global cases.Infection-related cancers showed the highest population-attributable fractions among Chinese adults,and most cancers could be attributed to behavioral and metabolic factors.The proportions of stage I for most cancer types were much higher in the USA than in China,except for esophageal cancer(78.2%vs.41.1%).The 5-year relative survival rates in China have improved substantially during 2000–2014,whereas survival for most cancer types in the USA was significantly higher than in China,except for upper gastrointestinal cancers.Our findings suggest that although substantial progress has been made in cancer control,especially in digestive system cancers in China,there was still a considerable disparity in cancer burden between China and the USA.More robust policies on risk factors and standardized screening practices are urgently warranted to curb the cancer growth and improve the prognosis for cancer patients.

An increasing cancer incidence among adults younger than 50 years has been reported for several types of cancer in multiple countries.We aimed to report cancer profiles and trends among young adults in China.Data from the China Cancer Registry Annual Report were used to estimate incidence and mortality among young adults(ages 20–49 years)in China in 2017,and an age-period-cohort model was employed to estimate the average annual percent change(AAPC)in incidence and mortality from 2000 to 2017.All 25 cancer types were grouped into obesity-or overweight-associated cancers(12 cancer types)and additional cancers(13 cancer types).In 2017,there were 681,178new cases and 214,591 cancer deaths among young adults in China.Among young adults,the most common cancers were thyroid,breast,cervical,liver,lung,and colorectal cancer,and the leading causes of cancer deaths were liver,lung,cervical,stomach,breast,and colorectal cancer.From 2000 to 2017,the cancer incidence increased for all cancers combined among young adults,with the highest AAPC(1.46%)for adults aged 20–24 years,while cancer mortality decreased,with the highest AAPC(-1.63%)for those aged 35–39 years.In conclusion,the cancer incidence in China has increased among young adults,while cancer mortality has decreased for nearly all ages.Cancer control measures,such as obesity control and appropriate screening,may contribute to reducing the increasing cancer burden among young adults.

It is of great significance to study the effects of desert plants on soil enzyme activities and soil organic carbon(SOC)for maintaining the stability of the desert ecosystem.In this study,we studied the responses of soil enzyme activities and SOC fractions(particulate organic carbon(POC)and mineral-associated organic carbon(MAOC))to five typical desert plant communities(Convolvulus tragacanthoides,Ephedra rhytidosperma,Stipa breviflora,Stipa tianschanica var.gobica,and Salsola laricifolia communities)in the proluvial fan in the eastern foothills of the Helan Mountain in Ningxia Hui Autonomous Region,China.We recorded the plant community information mainly including the plant coverage and herb and shrub species,and obtained the aboveground biomass and plant species diversity through sample surveys in late July 2023.Soil samples were also collected at depths of 0–10 cm(topsoil)and 10–20 cm(subsoil)to determine the soil physicochemical properties and enzyme activities.The results showed that the plant coverage and aboveground biomass of S.laricifolia community were significantly higher than those of C.tragacanthoides,S.breviflora,and S.tianschanica var.gobica communities(P<0.05).Soil enzyme activities varied among different plant communities.In the topsoil,the enzyme activities of alkaline phosphatase(ALP)andβ-1,4-glucosidas(βG)were significantly higher in E.rhytidosperma and S.tianschanica var.gobica communities than in other plant communities(P<0.05).The topsoil had higher POC and MAOC contents than the subsoil.Specifically,the content of POC in the topsoil was 18.17%–42.73%higher than that in the subsoil.The structural equation model(SEM)indicated that plant species diversity,soil pH,and soil water content(SWC)were the main factors influencing POC and MAOC.The soil pH inhibited the formation of POC and promoted the formation of MAOC.Conversely,SWC stimulated POC production and hindered MAOC formation.Our study aimed to gain insight into the effects of desert plant communities on soil enzyme activities and SOC fra

Background:Large disparities exist in liver cancer burden trends across countries but are poorly understood.We aimed to investigate the global trajectories of liver cancer burden,explore the driving forces,and predict future trends.Methods:Data on the liver cancer burden in 204 countries and territories from 1990 to 2019 were extracted from the Global Burden of Disease Study.The age-standardized incidence rate(ASIR)and age-standardized mortality rate(ASMR)trajectories were defined using growth mixture models.Five major risk factors contributing to changes in the ASIR or ASMR and socioeconomic determinants were explored using the identified trajectories.A Bayesian age-period-cohort model was used to predict future trends through 2035.Results:Three trajectories of liver cancer burden were identified:increasing,stable,and decreasing groups.Almost half of the American countries were classified in the decreasing group(48.6%for ASIR and ASMR),and the increasing group was the most common in the European region(ASIR,49.1%;ASMR,37.7%).In the decreasing group,the decrease of liver cancer due to hepatitis B contributed 63.4%and 60.4%of the total decreases in ASIR and ASMR,respectively.The increase of liver cancer due to alcohol use,hepatitis C,and hepatitis B contributed the most to the increase in the increasing group(30.8%,31.1%,and 24.2%for ASIR;33.7%,30.2%,and 22.2%for ASMR,respectively).The increasing group was associated with a higher sociodemographic index,gross domestic product per capita,health expenditure per capita,and universal health coverage(all P<0.05).Significant variations in disease burden are predicted to continue through 2035,with a disproportionate burden in the decreasing group.Conclusion:Global disparities were observed in liver cancer burden trajectories.Hepatitis B,alcohol use,and hepatitis C were identified as driving forces in different regions.

Background:The cancer burden in the United States of America(USA)has decreased gradually.However,China is experiencing a transition in its cancer profiles,with greater incidence of cancers that were previously more common in the USA.This study compared the latest cancer profiles,trends,and determinants between China and USA.Methods:This was a comparative study using open-source data.Cancer cases and deaths in 2022 were calculated using cancer estimates from GLOBOCAN 2020 and population estimates from the United Nations.Trends in cancer incidence and mortality rates in the USA used data from the Surveillance,Epidemiology,and End Results program and National Center for Health Statistics.Chinese data were obtained from cancer registry reports.Data from the Global Burden of Disease 2019 and a decomposition method were used to express cancer deaths as the product of four determinant factors.Results:In 2022,there will be approximately 4,820,000 and 2,370,000 new cancer cases,and 3,210,000 and 640,000 cancer deaths in China and the USA,respectively.The most common cancers are lung cancer in China and breast cancer in the USA,and lung cancer is the leading cause of cancer death in both.Age-standardized incidence and mortality rates for lung cancer and colorectal cancer in the USA have decreased significantly recently,but rates of liver cancer have increased slightly.Rates of stomach,liver,and esophageal cancer decreased gradually in China,but rates have increased for colorectal cancer in the whole population,prostate cancer in men,and other seven cancer types in women.Increases in adult population size and population aging were major determinants for incremental cancer deaths,and case-fatality rates contributed to reduced cancer deaths in both countries.Conclusions:The decreasing cancer burden in liver,stomach,and esophagus,and increasing burden in lung,colorectum,breast,and prostate,mean that cancer profiles in China and the USA are converging.Population aging is a growing determinant of incremental cancer burden.Progre

Cancer has become the most common cause of death in China.Owing to rapid economic development,improved livelihood,and shifts in risk factors,cancer epidemiology has experienced substantial changes during the past several decades.In this review,we aim to describe the current cancer epidemiology of the main types of cancer in China,report major risk factors associated with cancer development,and summarize the contributions of the Chinese government to controlling the cancer burden.A total of 4,064,000 new cases were diagnosed in China in 2016.The most frequent types are lung cancer(828,100;20.4%),colorectal cancer(408,000;10.0%),and gastric cancer(396,500;9.8%).Lung(657,000;27.2%),liver(336,400,13.9%),and stomach(288,500;12.0%)cancers are the 3 most deadly cancers in the general population.The 5-year survival rate for cancer has dramatically increased in recent decades.However,liver and particularly pancreatic cancers still have the poorest prognosis.The main modifiable risk factors associated with cancer development include infectious agents,smoking,alcohol consumption,obesity,unhealthful dietary habits,and inadequate physical activity.The Chinese government has made unremitting efforts to decrease the cancer burden,including cancer education and investment in cancer screening programs.

In 2020, stomach cancer was the fifth most commonly diagnosed cancer and the fourth leading cause of cancer-related death worldwide. Due to the relatively huge population base and the poor survival rate, stomach cancer is still a threat in China, and accounts for nearly half of the cases worldwide. Fortunately, in China, the incidence and mortality rates of stomach cancer presented a declining trend owing to the change of individual life styles and the persistent efforts to prevent stomach cancer from the governments at all levels. Helicobacter pylori(H. pylori)infection, poor eating habits, smoking, history of gastrointestinal disorders, and family history of stomach cancer are the main risk factors for stomach cancer in China. As a result, by taking risk factors for stomach cancer into account, specific preventive measures, such as eradicating H. pylori and implementing stomach cancer screening projects, should be taken to better prevent and decrease the burden of stomach cancer.

Burden of liver cancer:From epidemiology to prevention

Chinese Journal of Cancer Research 2022年第6期34卷 554-566页

作者： Qianru Li Maomao Cao Lin Lei Fan Yang He Li Xinxin Yan Siyi He shaoli zhang Yi Teng Changfa Xia Wanqing Chen Office of Cancer Screening National Cancer Center/National Clinical Research Center for Cancer/Cancer HospitalChinese Academy of Medical Sciences and Peking Union Medical CollegeBeijing 100021China Department of Cancer Prevention and Control Shenzhen Center for Chronic Disease ControlShenzhen 518020China

In this review,we offer a concise overview of liver cancer epidemiology in China and worldwide from the official databases of GLOBOCAN 2020 and the National Cancer Registry in China.We also summarized the evidence for the main risk factors associated with liver cancer risk and discuss strategies implemented in China to control the liver cancer burden.Overall,liver cancer was the sixth most commonly diagnosed cancer and the third leading cause of cancer-related death worldwide in 2020.Although China contributed to nearly half of cases across the world alone,the incidence and mortality rates of liver cancer presented a declining trend owing to the persistent efforts from the governments at all levels.The current liver cancer burden in China still faces an arduous challenge due to the relatively large population base as well as the substantially low survival rate(12.1%).To better control the liver cancer burden with the lowest cost,specific measures should be conducted by reducing exposure to established risk factors such as hepatitis B infection and aflatoxin.The promotion of surveillance is also an important method to prolong the survival of liver cancer.This review will provide basic information for future direction on the control of liver cancer burden.
