ABSTRACT

Objective:To investigate the change trend of etiological burden of disease of liver cancer in the Chinese population from 1990 to 2019.Methods:The descriptive epidemiologic method was conducted. Based on the Global Burden of Disease data from the Institute for Health Metrics and Evaluation at the University of Washington, the data related to liver cancer burden caused by hepatitis B virus (HBV) infection, hepatitis C virus (HCV) infection, alcohol, nonalcoholic steatohepatitis (NASH) and other factors, including number of new cases, the crude incidence rate, age-specific incidence rate, number of deaths, crude mortality rate and age-specific mortality rate, in the Chinese population from 1990 to 2019 were collected. The age-standardized rate was calculated based on the world standardized population structure in 2019 from the Global Burden of Disease data. Observation indicators: (1) the incidence of liver cancer caused by different etiologies in the Chinese population from 1990 to 2019; (2) the mortality of liver cancer caused by different etiologies in the Chinese population from 1990 to 2019; (3) the change trend of age-specific incidence rate of liver cancer caused by different etiologies in the Chinese population from 1990 to 2019; (4) the age-specific mortality rate of liver cancer caused by different etiologies in the Chinese population from 1990 to 2019. Count data were expressed as absolute numbers, percentages and ratio. Based on the junction point regression model, the Joinpoint software (V.4.9.1.0) was used to calculate the annual percentage change, average annual percentage change (AAPC) and 95% confidence intervals ( CI) of age-specific incidence rate and age-specific mortality rate of liver cancer caused by different etiologies. Results:(1) The incidence of liver cancer caused by different etiologies in the Chinese population from 1990 to 2019. From 1990 to 2019, the number of new cases of liver cancer in Chinese population decreased from 236 825 to 210 462, and the crude incidence rate decreased from 20.01/100,000 to 14.80/100,000. The new cases of liver cancer caused by HBV infection, HCV infection and other factors showed a downward trend, and the absolute change rates were ?14.76%, ?3.98% and ?26.67%, respectively. The new cases of liver cancer caused by alcohol and NASH showed a increase trend, and the absolute change rates were 9.31% and 13.91%, respectively. (2) The mortality of liver cancer caused by different etiologies in the Chinese population from 1990 to 2019. From 1990 to 2019, the number of deaths of liver cancer in Chinese population decreased from 232 449 to 187 700, and the crude mortality rate decreased from 19.64/100,000 to 13.20/100,000. The number of deaths of liver cancer caused by HBV infection, HCV infection and other factors showed a down-ward trend, and the absolute change rates were ?23.34%, ?10.99% and ?33.75%, respectively. The number of deaths of liver cancer caused by alcohol showed a slow downward trend, and the absolute change rate was ?0.51%. The number of deaths of liver cancer caused by NASH showed a increase trend, and the absolute change rate was 6.03%. (3) The change trend of age-specific incidence rate of liver cancer caused by different etiologies in the Chinese population from 1990 to 2019. From 1990 to 2019, the AAPC of age-specific incidence rate of liver cancer caused by HBV infection, HCV infection, alcohol, NASH and other factors was ?3.61%(95% CI as ?4.10% to ?3.11%), ?3.57%(95% CI as ?3.99% to ?3.14%), ?2.79%(95% CI as ?3.24% to ?2.33%), ?2.65%(95% CI as ?3.09% to ?2.21%) and ?3.62%(95% CI as ?4.05% to ?3.19%), respectively. (4) The age-specific mortality rate of liver cancer caused by different etiologies in the Chinese population from 1990 to 2019. From 1990 to 2019, the AAPC of age-specific mortality rate of liver cancer caused by HBV infection, HCV infection, alcohol, NASH and other factors was ?3.92%(95% CI as ?4.42% to ?3.41%), ?3.90%(95% CI as ?4.45% to ?3.35%), ?3.15%(95% CI as ?3.71% to ?2.58%), ?2.86%(95% CI as ?3.34% to ?2.38%) and ?4.09%(95% CI as ?4.64% to ?3.55%), respectively. Conclusions:From 1990 to 2019, the liver cancer burden of the Chinese population shows an overall downward trend, in which the liver cancer burden caused by HBV and HCV infection decreases the most, but HBV and HCV infection is still the main reason for the heavy burden of liver cancer. The age-specific incidence rate and age-specific mortality rate of liver cancer caused by alcohol and NASH show a downward trend, but the number of new cases of liver cancer caused by alcohol and NASH shows significant growth. The liver cancer burden caused by other factors shows a downward trend.

ABSTRACT

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.

ABSTRACT

Objective:To analyze the changing trend of the incidence and mortality rates of liver cancer in the Chinese population from 1990 to 2019, and predict the future development trend of liver cancer.Methods:The descriptive epidemiologic method was conducted. Based on the Global Burden of Disease data from the Institute for Health Metrics and Evaluation at the University of Washington, the crude incidence rate and total number, crude mortality rate and total number, age- and sex-specific incidence rate and number, age- and sex-specific mortality rate and number of liver cancer in the Chinese population from 1990 to 2019 were collected. The age-standardized rate was calculated using the year 2000 China's standard population. Observation indicators: (1) the incidence and mortality of liver cancer in the Chinese population from 1990 to 2019; (2) changing trend of the age-standardized incidence and mortality rates of liver cancer in the Chinese population from 1990 to 2019; (3) prediction of the incidence and mortality of liver cancer in the Chinese population during 2020-2044. Count data were described as absolute numbers, percentages and ratios. The Joinpoint V.4.9.0.0 software was used to calculate the annual percent change (APC), average annual percent change (AAPC) and its 95% confidence interval ( CI) of age-standardized incidence and mortality rates of liver cancer in different time periods. The age-period-cohort model in the Nordpred package of R software (V.4.1.1) was used to predict the incidence and mortality of liver cancer in the Chinese population during 2020-2044. Results:(1) The incidence and mortality of liver cancer in the Chinese population from 1990 to 2019: the crude incidence rate and the age-standardized incidence rate of liver cancer in the Chinese population decreased from 20.01/100,000 and 24.31/100,000 in 1990 to 14.80/100,000 and 9.71/100,000 in 2019, respectively. The crude incidence rate and the age-standardized incidence rate of liver cancer in the Chinese male popula-tion decreased from 27.88/100,000 and 34.76/100,000 in 1990 to 22.05/100,000 and 15.22/100,000 in 2019, respectively. The crude incidence rate and the age-standardized incidence rate of liver cancer in the Chinese female population decreased from 11.63/100,000 and 13.51/100,000 in 1990 to 7.26/100,000 and 4.29/100,000 in 2019, respectively. The crude mortality rate and the age-standardized mortality rate of liver cancer in the Chinese population decreased from 19.64/100,000 and 23.97/100,000 in 1990 to 13.20/100,000 and 8.44/100,000 in 2019, respectively. The crude mortality rate and the age-standardized mortality rate of liver cancer in the Chinese male population decreased from 27.03/100,000 and 34.10/100,000 in 1990 to 19.18/100,000 and 13.03/100,000 in 2019, respectively. The crude mortality rate and the age-standardized mortality rate of liver cancer in the Chinese female population decreased from 11.78/100,000 and 13.64/100,000 in 1990 to 6.98/100,000 and 3.97/100,000 in 2019, respectively. (2) Changing trend of the age-standardized incidence and mortality rates of liver cancer in the Chinese population from 1990 to 2019: the trend of age-standardized incidence rate of liver cancer in the Chinese population could be divided into 5 periods, namely year 1990 to 1996, year 1996 to 2001, year 2001 to 2005, year 2005 to 2010 and year 2010 to 2019. In these 5 periods, the APC of age-standardized incidence rate changed from 1.27%(95% CI as 0.81% to 1.73%, P<0.001) to 1.12%(95% CI as 0.91% to 1.33%, P<0.001) of the total Chinese population, from 1.68%(95% CI as 1.19% to 2.17%, P<0.001) to 1.65%(95% CI as 1.42% to 1.87%, P<0.001) of the Chinese male population and from 0.21%(95% CI as -0.32 % to 0.75%, P=0.406) to -0.14%(95% CI as -0.40% to 0.11%, P=0.241) of the Chinese female population, respectively. The trend of age-standardized mortality rate of liver cancer in the Chinese population could be divided into 5 periods, namely year 1990 to 1996, year 1996 to 2000, year 2000 to 2005, year 2005 to 2012 and year 2012 to 2019. In these 5 periods, the APC of age-standardized mortality rate changed from 1.47%(95% CI as 0.74% to 2.20%, P=0.001) to 1.34%(95% CI as 0.78% to 1.90%, P<0.001) of the total Chinese population, from 1.96%(95% CI as 1.18% to 2.75%, P<0.001) to 1.79%(95% CI as 1.18% to 2.41%, P<0.001) of the Chinese male population and from 0.14%(95% CI as -0.54% to 0.82%, P=0.670 ) to 0.48%(95% CI as 0.02% to 0.93%, P=0.041) of the Chinese female population, respectively. From 1990 to 2019, the AAPC of age-standardized incidence and age-standardized mortality rates of liver cancer were -3.22%(95% CI as -3.41% to -3.03%) and -3.51%(95% CI as -3.82% to -3.19%) in the Chinese population, -2.90%(95% CI as -3.10% to -2.71%) and -3.22%(95% CI as -3.57% to -2.88%) in the Chinese male population, -3.96%(95% CI as -4.17% to -3.76%) and -4.13%(95% CI as -4.43% to -3.82%) in the Chinese female population, respectively. (3) Prediction of the incidence and mortality of liver cancer in the Chinese population during 2020-2044: the age-standardized incidence rate of liver cancer would decrease from 9.51/100,000 in 2015-2019 to 5.78/100,000 in 2040-2044 in the Chinese population, from 14.84/100,000 in 2015-2019 to 9.75/100,000 in 2040-2044 in the Chinese male population and from 4.28/100,000 in 2015-2019 to 1.88/100,000 in 2040-2044 in the Chinese female population, respectively. The age-standardized mortality rate of liver cancer would decrease from 8.40/100,000 in 2015-2019 to 4.62/100,000 in 2040-2044 in the Chinese population, from 12.91/100,000 in 2015-2019 to 7.59/100,000 in 2040-2044 in the Chinese male population and from 4.01/100,000 in 2015-2019 to 1.70/100,000 in 2040-2044 in the Chinese female population, respectively. The incidence number and mortality number of liver cancer from 2020 to 2044 would remain stable at around 160,000 per year and 140,000 per year in the Chinese population, 128,500 per year and 109,000 per year in the Chinese male population, 36,000 per year and 34,900 per year in the Chinese female population, respectively. Conclusion:The incidence and mortality rates of liver cancer in the Chinese popula-tion show a significant downward trend from 1990 to 2019, and the incidence number and mortality number of liver cancer in the Chinese population will remain stable above 100,000 during 2020-2044.

ABSTRACT

In China, the survival rate of liver cancer remains low while the mortality rate is high. Effectively reducing the burden of liver cancer is still a major challenge in the field of public health and chronic disease prevention in the Chinese population. Optimizing screening strategies for liver cancer remains a profound approach to secondary prevention worthy of continuous exploration. To address this pressing issue, the Bureau of Disease Control and Prevention of the National Health Commission commissioned this guideline. The National Cancer Center of China initiated the guideline development and convened a multidisciplinary expert panel and working groups. Following the World Health Organization Handbook for Guideline Development, this guideline integrated the most up-to-date evidence of liver cancer screening, China's national conditions, and existing practical experience in liver cancer screening. Evidence-based recommendations on the target population, screening technologies, surveillance strategies, and other key points across the process of liver cancer screening and surveillance management were provided. This guideline would help standardize the practice of liver cancer screening in China.

ABSTRACT

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. Progress in cancer prevention and care in the USA, and measures to actively respond to population aging, may help China to reduce the cancer burden.

ABSTRACT

In China, the malignant tumor with the highest incidence and motality is lung cancer (LC). As screening and early detection and treatment are effective in reducing LC mortality, formulating a guideline in line with China′s national conditions for the screening and early detection and treatment of LC will greatly promote the homogeneity and accuracy of LC screening, and result in an improvement of the effectiveness of LC screening. Commissioned and directed by the Disease Prevention and Control Bureau of the National Health Commission of the People′s Republic of China, the guidline was initiated by the National Cancer Center of China and formulated with joint effort by experts from different disciplines. Following the principles and methods in WHO Handbook for Guideline Development, the guidline integrates the latest development in LC screening and early diagnosis and treatment worldwide while fully considering China′s national conditions and practical experience in LC screening. It provides detailed evidence-based recommendations for different aspects of LC screening, such as the targeted population, the technologies and the procedures, to regulate the practices of LC screening and early diagnosis and treatment and enhance the effectiveness of the prevention and control of LC in China.

ABSTRACT

In the past decade, the incidence and mortality of malignant tumors in China have been growing as a serious public health problem. Health literacy is closely related to the individual cancer risk awareness, early cancer symptom recognition, cancer screening behavior, treatment compliance, disease self-management ability and outcome. It also has an important impact on the occurrence, development and outcome of cancer and plays an important role in the tertiary cancer prevention. This issue focuses on the consciousness of cancer prevention, early detection, early diagnosis and early treatment, as well as the demand of and access to the cancer prevention and treatment knowledge, and could provide reference for cancer prevention and control in urban residents.

ABSTRACT

Objective@#To understand the health literacy and relevant factors of cancer prevention consciousness in Chinese urban residents from 2015 to 2017.@*Methods@#A cross-sectional survey was conducted in 16 provinces covered by the Cancer Screening Program in Urban China from 2015 to 2017. A total of 32 257 local residents aged ≥18 years old who could understand the investigation procedure were included in the study by using the cluster sampling method and convenient sampling method. All local residents were categorized into four groups, which contained 15 524 community residents, 8 016 cancer risk assessment/screening population, 2 289 cancer patients and 6 428 occupational population, respectively. The self-designed questionnaire was used to collect the information of demographic characteristics and cancer prevention consciousness focusing on nine common risk factors, including smoking, alcohol, fiber food, food in hot temperature or pickled food, chewing betel nut, helicobacter pylori, moldy food, hepatitis B infection, estrogen, and exercise. The logistic regression model was adopted to identify the influencing factors.@*Results@#The overall health literacy of the cancer prevention consciousness was 77.4% (24 980 participants), with 77.4% (12 018 participants), 79.9% (6 406 participants), 77.2% (1 766 participants) and 74.5% (4 709 participants) in each group (P<0.001). The correct response rates for nine risk factors ranged from 55.2% to 93.0%. The multivariate logistic regression analysis showed that compared with community residents, people with primary school level education or below, and the number of people living together in the family <3, the cancer risk assessment/screening intervention population, cancer patients, those with junior high school level educationor above and the number of people living in the family ≥3 had better health literacy of the cancer prevention consciousness (all P values <0.05). Compared with females, 39 years old and below, government-affiliated institutions or civil servants, from the eastern region, males, older than 40 years, company or enterprise employees, and from the middle or western region had worse health literacy of the cancer prevention consciousness (all P values <0.05).@*Conclusion@#The health literacy of the cancer prevention consciousness in Chinese urban residents should be improved. The cancer screening intervention, gender, age, education, occupation, the number of people co-living in the family, and residential region were associated with the health literacy of the cancer prevention consciousness.

ABSTRACT

Objective@#To understand the consciousness of the cancer early detection among urban residents and identify the influencing factors from 2015 to 2017.@*Methods@#A cross-sectional survey was conducted in 16 provinces covered by the Cancer Screening Program in Urban China from 2015 to 2017. A total of 32 257 local residents aged ≥18 years old who could understand the investigation procedure were included in the study by using the cluster sampling method and convenient sampling method. All local residents were categorized into four groups, which contained 15 524 community residents, 8 016 cancer risk assessment/screening population, 2 289 cancer patients and 6 428 occupational population, respectively. Self-designed questionnaires were used to collect population, socioeconomic indicators, self-cancer risk assessment, regular participation in physical examination and other information. The multivariate logistic regression model was used to identify the factors of people who had not regularly participated in the regular physical examination in the past five years.@*Results@#The self-assessment results of 32 357 residents showed that there were 27.54% (8 882) of total study population with self-reported cancer risk, 45.48% (14 671) without cancer risk and 26.98% (8 704) with unclear judgement on their own cancer risk. Among population with cancer risk, 79.84% (7 091) considered physical examination accounted. In the past five years, there were 21 105 (65.43%) residents participated in regular physical examination and 11 148 (34.56%) participated in non-scheduled one, respectively. The multivariate logistic regression analysis showed that compared with unmarried and western region residents, divorced, middle and eastern region residents had a stronger consciousness to participate in the regular physical examination (P<0.05). Compare with residents with annual household income less than 20 000 CNY in 2014, cancer risk assessment/screening intervention population, and self-assessment with cancer risk, residents with annual household income between 20 000 CNY and 59 000 CNY in 2014, occupational population, community residents, cancer patients, self-reported cancer-free risk, and self-assessment with unclear judgement of cancer risk were less likely to participate in the regular physical examination (all P values <0.05).@*Conclusion@#From 2015 to 2017, the Chinese urban residents had a acceptable consciousness of the cancer early detection. The marital status, annual household income, population group and self-assessment of cancer risk were related to the consciousness of the cancer early detection of people who had not participated in the regular physical examination in the past five years.

ABSTRACT

Objective@#To understand the consciousness of the cancer early diagnosis among urban residents and identify the related factors from 2015 to 2017.@*Methods@#A cross-sectional survey was conducted in 16 provinces covered by the Cancer Screening Program in Urban China from 2015 to 2017. A total of 32 257 local residents aged ≥18 years old who could understand the investigation procedure were included in the study by using the cluster sampling method and convenient sampling method. All local residents were categorized into four groups, which contained 15 524 community residents, 8 016 cancer risk assessment/screening population, 2 289 cancer patients and 6 428 occupational population, respectively. The general demographic characteristics, the consciousness of the cancer early diagnosis (whether people would have a willingness or encourage their relatives/friends to confirm the abnormal results once which were detected from the physical examination) and other information were collected by using the self-designed questionnaire. The non-conditional logistic regression model was used to identify the relateol factors related to the consciousness of the cancer early diagnosis.@*Results@#As for residents with abnormal result from the physical examination, 89.29% (28 802) of residents would choose to seek medical treatment for further diagnosis. If their relatives/friends had abnormal results from the physical examination, 89.55% (28 886) of residents would encourage their relatives/friends to confirm the diagnosis in time. The non-conditional logistic regression model analysis showed that compared with the public institution staff/civil servants, annual household income less than 20 000 CNY, the western region and the cancer risk assessment/screening intervention population, the company staff, annual household income about 40 000 CNY and more, and the residents from the middle and eastern region had a stronger consciousness to seek further diagnosis; while the unemployed residents and community residents were less likely to seek further diagnosis (P<0.05).@*Conclusions@#From 2015 to 2017, the Chinese urban residents had a good consciousness of the cancer early diagnosis. Occupation, annual household income, residential region and population group were related to the consciousness of the cancer early diagnosis.

ABSTRACT

Objective@#To understand the consciousness of the cancer early treatment and its demographic and socioeconomic factors.@*Methods@#A cross-sectional survey was conducted in 16 provinces covered by the Cancer Screening Program in Urban China (CanSPUC) from 2015 to 2017. A total of 32 257 local residents aged ≥18 years old who could understand the investigation procedure were included in the study by using the cluster sampling method and convenient sampling method. All local residents were categorized into four groups, which contained 15 524 community residents, 8 016 cancer risk assessment/screening population, 2 289 cancer patients and 6 428 occupational population, respectively. The questionnaire collected personal information, the consciousness of the cancer early treatment and relevant factors. The Chi square test was used to compare the difference between the consciousness of the cancer early treatment and relevant factors among the four groups. The logistic regression model was used to analyze the influencing factors related to the consciousness of the cancer early treatment.@*Results@#With the assumption of being diagnosed as precancer or cancer, 89.97% of community residents, 91.84% of cancer risk assessment/screening population, 93.00% of cancer patients and 91.52% of occupational population would accept active treatments (P<0.001). If the immediate family members were diagnosed as precancer or cancer, people who would encourage their family members to receive early treatment in the four groups accounted for 91.96%, 91.94%, 92.44% and 91.55%, respectively (P<0.001). The company employees, annual household income with 40 000 yuan and more and other three groups had a relatively better consciousness of the cancer early treatment (P<0.05). Male, widowed, unemployed and from the central and western regions had a relatively worse consciousness of the cancer early treatment (P<0.05).@*Conclusion@#Residents in urban China participants had a good consciousness of the cancer early treatment. The marital status, occupation, annual household income and residential regions were major factors related to the consciousness of the cancer early treatment.

ABSTRACT

Objective@#To understand the health literacy of the cancer prevention and treatment among urban residents of China, and explore the related factors.@*Methods@#A cross-sectional survey was conducted in 16 provinces covered by the Cancer Screening Program in Urban China (CanSPUC) from 2015 to 2017. A total of 32 257 local residents aged ≥18 years old who could understand the investigation procedure were included in the study by using the cluster sampling method and convenient sampling method. All local residents were categorized into four groups, which contained 15 524 community residents, 8 016 cancer risk assessment/screening population, 2 289 cancer patients and 6 428 occupational population, respectively. The health literacy of the cancer prevention, early discovery, early diagnosis, early treatment and the demands of cancer prevention and treatment knowledge was analyzed. The level of health literacy among different groups were calculated and compared. The binary logistic regression model was used to analyze the influencing factors of the health literacy of the cancer prevention and treatment.@*Results@#The level of health literacy of the cancer prevention and treatment was 56.97% among all study population; in each group it was 55.01% for community residents, 59.08% for cancer risk assessment/screening population, 61.99% for cancer patients and 57.31% for occupational population, respectively (P<0.001). The level of health literacy of the cancer prevention and treatment of residents aged 50 to 69 years old, other occupational groups, unmarried, the central and western region residents and the group with unclear self-assessment of cancer risk was significantly lower than that of residents younger than 40 years old, personnel of public institutions/civil servants, married, the eastern region residents and the group whose self-assessment without cancer risk (P<0.05) . The level of health literacy of cancer prevention and treatment of females, people who went to high school or over, cancer risk assessment/screening population, cancer patients and occupational population was significantly higher than that of males, people who had an education level of primary school or below and community residents (P<0.05) .@*Conclusion@#The health literacy of the cancer prevention and treatment of urban residents in China was relatively high, but there was still room for improvement. Gender, age, educational level, occupation, region, marital status, self-assessment of cancer risk, and type of respondents were the key influencing factors of the health literacy of the cancer prevention and treatment. Male, 50-69 years old, lower educational level, central and western regions, unclear cancer risk self-assessment, and without specific environmental exposure to cancer prevention and treatment knowledge or related risk factors were the characteristics of the key intervention group of the health literacy of the cancer prevention and treatment.

ABSTRACT

Objective@#To investigate the demand and access to the cancer prevention and treatment knowledge and related factors among urban residents in China from 2015 to 2017.@*Methods@#A cross-sectional survey was conducted in 16 provinces covered by the Cancer Screening Program in Urban China from 2015 to 2017. A total of 32 257 local residents aged ≥18 years old who could understand the investigation procedure were included in the study by using the cluster sampling method and convenient sampling method. All local residents were categorized into four groups, which contained 15 524 community residents, 8 016 cancer risk assessment/screening population, 2 289 cancer patients and 6 428 occupational population, respectively. The self-designed questionnaire was used to collect the information of general demographic characteristics, the demand and access to cancer prevention and treatment knowledge, and the influencing factors of the attitude. The Chi-square test was used to analyze the difference of the demand of the cancer prevention knowledge among different groups and the corresponding factors of the cancer prevention and treatment knowledge were analyzed by using the logistic regression model.@*Results@#The proportion of residents who need the cancer prevention and treatment knowledge was 79.5%. The demand rate of the inducement, symptom and diagnosis methods of cancer in the occupational population was highest, about 66.8%, 71.0% and 20.8%, respectively. The demand rate of treatment methods and cost in current cancer patients was the highest, about the 45.9% and 21.9%, respectively. The top three sources to acquire the cancer prevention and treatment knowledge were "broadcast or television" (69.5%), "books, newspapers, posters or brochures" (44.7%) and "family and friends" (33.8%). The multivariate analysis showed that compared with public institution personnel/civil servants, unmarried/cohabiting/divorced/widowed and others, annual household income less than 20 000 CNY, from the eastern region, people without cancer diagnosis and people with self-assessment of cancer risk, the demand rate of cancer prevention and treatment knowledge was higher in enterprise personnel/workers, married, annual household income between 60 000 CNY and 150 000 CNY, from the central region, people with cancer and people with unclear cancer risk (all P values <0.05).@*Conclusion@#There was a high demand for the cancer prevention and treatment knowledge among urban residents in China from 2015 to 2017. The main access to the knowledge is from the radio or television. The occupation, marital status, annual household income, residential region, health status and risk of disease were the main factors of the demand of the cancer prevention and treatment knowledge.

ABSTRACT

The health literacy refers to the ability of individuals to acquire and understand basic health information and services and use them to make the right decisions to maintain and promote their health. Health literacy data focusing on cancer prevention and control was limited in China. In order to understand the health literacy and awareness of cancer risk factors and the cancer screening, early diagnosis and treatment in Chinese urban residents and compare the effect of different stages of the cancer intervention, the Cancer Screening Program in Urban China (CanSPUC) program, supported by the National Key Public Health Program, conducted a survey on the health literacy of the cancer prevention and treatment among urban residents in 16 provinces nationwide from 2015 to 2017. Four subgroups were designed in this survey, including (1) general population who have never participated in any cancer screening programs at a community-level; (2) individuals who have previously attended the CanSPUC program for cancer risk assessment or screening intervention; (3) cancer patients who were receiving treatment in local hospitals; (4) a special group from employees of government and public institutions (non-health system), state-owned enterprises and private enterprises (to have better understand on the impact of socioeconomic factors). The self-designed questionnaire covered six parts, including basic information, consciousness of common risk factors to cancer, awareness of early detection, awareness of early diagnosis, awareness of early treatment, and the needs and approaches for knowledge of cancer prevention and treatment. A total of 32 257 individuals were included in the final analyses. This paper landscaped the overall design of the survey, including participants, domains of the instrument, quality control, basic characteristics of the included individuals. These descriptions are applicable to each individual report of the current special issue of "Health Literacy of Cancer Control in Urban China" and future reports, in which more detailed results are and will be reported. The findings of this survey could provide some useful implications for similar researches in the future.

ABSTRACT

This article reviews the literature on health literacy and cancer prevention, screening, treatment and prognosis. A large number of studies have shown that health literacy is positively correlated with public cancer risk awareness, cancer knowledge awareness rate, and cancer screening behavior, and positively correlated with the health service resource utilization ability of cancer patients, treatment compliance, and quality of life, and negatively correlated with the unhealthy lifestyle such as smoking and drinking. Some studies have problems such as small sample size, limited population, and inappropriate design. Some studies do not support the conclusions above. Therefore, multi-center, large-scale clinical studies and cohort studies should be conducted to provide more robust evidence for the relationship between the health literacy and cancer prevention, screening, and treatment.

ABSTRACT

Objective@#The registration data of local cancer registries from 2008 to 2012 were collected by National Central Cancer Registry to estimate the incidence and mortality of female breast cancer in China.@*Methods@#Data from 135 registries were qualified and selected in the final analysis, and each registry at least has submitted data from 2010 to 2012. Cancer incidence and mortality analyses were stratified by area (urban/rural, eastern/middle/western areas) and age group. The age composition of standard population of Chinese census in 2000 and Segi′s population were used for age-standardized incidence and mortality in China and worldwide, respectively.@*Results@#A total of 135 registries were recruited in the analysis, covering 629 333 910 person-years (382 669 450 in urban and 246 664 460 in rural). About 13, 258 cases of female breast cancer were diagnosed and 32 205 cases were dead between 2008 and 2012. Female breast cancer incidence was 42.67/100, 000 and age-standardized rate calculated by worldwide standard population was 28.87/100, 000. The crude incidence of urban area was 51.85/100, 000, higher than 28.29/100, 000 of rural area, and the crude incidence of eastern area was 46.35/100, 000, higher than 36.38/100, 000 of middle area and 27.60/100, 000 of western area. The age-specific incidence increased with age and reached the peak at age 55-59 (96.36/100, 000), and declined at age 60. The age-standardized incidence rate by Chinese standard population increased 30.56% from 2003 to 2012. The increase rate of rural area was 72.32%, faster than 23.48% of urban area. Female breast cancer mortality was 10.36/100, 000 and the age-standardized rate calculated by worldwide standard population was 6.61/100, 000. The crude mortality of urban area was 11.64/100, 000, higher than 8.36/100, 000 of rural area, and the crude mortality of eastern area was 10.81/100, 000, higher than 7.38/100, 000 of middle area and 9.90/100, 000 of western area. The age-specific incidence increased with age and reached the peak at age above 85 (61.25/100, 000). Age-standardized incidence rate by Chinese standard population remained stable during the period of 2003-2012 (6.23%). The mortality rate mainly increased in rural area (54.94%), while decreased 2.32% in urban area over the 10 years.@*Conclusions@#Although the incidence and mortality of breast cancer in China are comparatively low worldwide, in China the incidence and mortality of female breast cancer have rose to the first and sixth place respectively among all the female cancers. The disease burden of breast cancer is very different between urban and rural area. Therefore, the targeted measure and strategy of control and prevention according to the area difference are needed.

ABSTRACT

Objective@#To systematically review the quality and reporting quality of colorectal cancer screening guidelines, and to provide reference for the update of colorectal cancer screening guidelines and colorectal cancer screening in China.@*Methods@#"Colorectal cancer", "colorectal tumor", "screening", "screening", "guide", "consensus", "Colorectal cancer", "Colorectal neoplasms", "Screening", "Early Detection of Cancer", "Guideline" and "recommendation" were used as search keywords. The literature retrieval for all the Chinese and English guidelines published before April 2018 was conducted by using PubMed, Embase, Web of Science, China National Knowledge Infrastructure (CNKI), Wanfang Data, China Biology Medicine disc (CBMdisc), Cochrane Library, Guideline International Network, China Guidelines Clearinghouse (CGC) and the official website of the US Preventive Services Task Force (USPSTF), the American Cancer Society (ACS), International Agency for Research on Cancer (IARC), Australia Cancer Council (ACC) and Association of Coloproctology of Great Britain & Ireland (ACPGBI). The inclusion criteria were independent guidance documents for colorectal cancer screening. The language is limited to Chinese and English. The exclusion criteria were literature on interpretation, evaluation, introduction, etc., as well as the translated version of the guide and old guides. The quality and reporting norms of colorectal cancer screening guidelines were compared and evaluated using the European Guideline Research and Assessment Tool (AGREE Ⅱ) and the Practice Guideline Reporting Standard (RIGHT).@*Results@#A total of 15 guides were included. The results of the AGREE Ⅱ quality evaluation showed that the overall quality of 15 guides was high. Among them, there were 9 guides with an overall score of 50 or more, 10 with a recommendation level of "A", and 2 with a rating of "B". There were 3 guides for "C"; each guide scores higher in scope and purpose, and clarity, and scores vary greatly in the areas of participants, rigor, applicability, and independence. The results of the RIGHT evaluation showed that 15 guides were insufficient in six areas except for background information, evidence, recommendations, reviews and quality assurance, funding and conflict of interest statements and management, and other aspects.@*Conclusion@#The overall quality of included guidelines for colorectal cancer screening is high, but the normative nature needs to be strengthened.
