RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

OBJECTIVE: To understand the epidemic status and influencing factors of intestinal parasitic diseases among rural children in Henan Province. METHODS: According to the Scheme for The National Survey on Current Status of Major Human Parasitic Diseases in China, the survey counties were selected based on the ecological zones and economic levels in Henan Province between 2014 and 2015. Then, the included counties were stratified according to the topography and economic levels. A township was randomly sampled from each stratum, and a village was randomly sampled from each township as the study site. Finally, a total of 104 study sites from 35 counties were enrolled for the survey of intestinal parasitic diseases in children. At least 250 fresh stool samples were collected from each study site for detection of intestinal helminth eggs with the Kato-Katz technique, for the identification of Necator americanus and Ancylostoma duodenale with the fecal culture method, and for the detection of intestinal protozoa trophozoite and cyst with the physiological saline smear and iodine staining techniques. In addition, the Enterobius vermicularis and tapeworm eggs were detected in children aged 3 to 6 years using the adhesive cellophane-tape perianal swab method. RESULTS: The overall prevalence of intestinal parasitic infections was 3.21% (214/6 671) among rural children in Henan Province, and the prevalence of intestinal helminthes (2.62%, 175/6 671) was higher than that of intestinal protozoa (0.60%, 40/6 671). A total of 12 species of intestinal parasites were found, including 4 nematodes species, one trematode species, and 7 protozoa species, and the highest infection was seen in E. vermicularis (2.47%, 161/6 671). Among the four ecological zones in Henan Province, the greatest prevalence of intestinal parasitic infections was detected among children in the Qinba Mountain Ecological Zone (5.85%, 90/1 538). There was no gender-specific difference in the prevalence of intestinal parasitic infections in children (P > 0.05); however, there were age- (χ2 = 32.762, P < 0.05) and education level-specific differences in the prevalence of intestinal parasitic infections in children (χ2 = 67.507, P < 0.05), with the greatest prevalence of E. vermicularis infection seen in all species of intestinal parasites in children at all age groups. Multivariate non-conditional logistic regression analysis showed that high education level, high coverage of harmless toilets, drinking tap water and deworming were protective factors for intestinal parasitic infections in children in Henan Province. The overall prevalence of intestinal parasitic infections appeared a tendency towards a gradual decline among children in Henan Province as compared to the previous two surveys. CONCLUSIONS: The overall prevalence of intestinal parasitic infections shows a tendency towards a remarkable decline among children in Henan Province. E. vermicularis infection should be given a priority for future parasitic disease control activities among rural children in Henan Province.

RESUMO

Developing safe, efficient and environment-friendly energy storage systems continues to inspire researchers to synthesize new electrode materials. Doping or substituting host material by some guest elements has been regarded as an effective way to improve the performance of supercapacitors. In this work, single-phase CuCo2-xNixS4 materials were synthesized by a facile two-step hydrothermal method, where Co in CuCo2S4 was substituted by Ni. Cobalt could be easily substituted with Ni in a rational range to keep its constant phase. But, a high content of Ni resulted in a multi-phase composite. Among a series of CuCo2-xNixS4 materials with different Ni/Co mole ratios, CuCo1.25Ni0.75S4 material presented a significantly high specific capacitance (647 F g-1 or 272 C g-1 at 1 A g-1) and the best cycling stability (∼98% specific capacitance retention after 10,000 charge-discharge cycles), which was mainly due to the modified composition, specific single phase, higher electroconductivity, more electroactive sites and the synergistic effect between Ni and Co. Moreover, the assembled asymmetric capacitor using CuCo1.25Ni0.75S4 as a positive electrode and activated carbon as a negative electrode delivered a high energy density of 31.8 Wh kg-1 at the power density of 412.5 W kg-1. These results demonstrated that ternary metal sulfides of CuCo2-xNixS4 are promising electrode materials for high-performance supercapacitors.

RESUMO

Estimating the feed intake of grazing herbivores is critical for determining their nutrition, overall productivity and utilization of grassland resources. A 17-day indoor feeding experiment was conducted to evaluate the potential use of Medicago sativa as a natural supplement for estimating the total feed intake of sheep. A total of 16 sheep were randomly assigned to four diets (four sheep per diet) containing a known amount of M. sativa together with up to seven forages common to typical steppes. The diets were: diet 1, M. sativa + Leymus chinensis + Puccinellia distans; diet 2, species in diet 1 + Phragmites australis; diet 3, species in diet 2 + Chenopodium album + Elymus sibiricus; and diet 4, species in diet 3 + Artemisia scoparia + Artemisia tanacetifolia. After faecal marker concentrations were corrected by individual sheep recovery, treatment mean recovery or overall recovery, the proportions of M. sativa and other dietary forages were estimated from a combination of alkanes and long-chain alcohols using a least-square procedure. Total intake was the ratio of the known intake of M. sativa to its estimated dietary proportion. Each dietary component intake was obtained using total intake and the corresponding dietary proportions. The estimated values were compared with actual values to assess the estimation accuracy. The results showed that M. sativa exhibited a distinguishable marker pattern in comparison to the other dietary forage species. The accuracy of the dietary composition estimates was significantly (P < 0.001) affected by both diet diversity and the faecal recovery method. The proportion of M. sativa and total intake across all diets could be accurately estimated using the individual sheep or the treatment mean recovery methods. The largest differences between the estimated and observed total intake were 2.6 g and 19.2 g, respectively, representing only 0.4% and 2.6% of the total intake. However, they were significantly (P < 0.05) biased for most diets when using the overall recovery method. Due to the difficulty in obtaining individual sheep recovery under field conditions, treatment mean recovery is recommended. This study suggests that M. sativa, a natural roughage instead of a labelled concentrate, can be utilized as a dietary supplement to accurately estimate the total feed intake of sheep indoors and further indicates that it has potential to be used in steppe grassland of northern China, where the marker patterns of M. sativa differ markedly from commonly occurring plant species.

RESUMO

Objective: To characterize the clinical epidemiological features of primary lung cancer patients based on massive clinical data. Methods: The demographic and histological information of 8 081 primary lung cancer patients who were initially identified from 1 January 2012 to 31 December 2013 in 16 hospitals from 6 provinces were retrospectively analyzed to determine the characteristics of different histological subtypes among different gender, age-group and birth cohort. Results: Among the 8 081 lung cancer patients, 5 422 (67.10%) were male and 2 659 (32.90%) were female, the average age was (60.96±10.14) years. The most common histological subtypes of lung cancer successively were adenocarcinoma (ADC), squamous cell carcinoma (SCC), small cell carcinoma and large cell carcinoma, and the proportions of these subtypes were 53.13%, 24.51%, 14.59% and 0.66%, respectively, which collectively accounted for 92.89%. The current highest smoking rate was observed in SCC patients, which was 62.45%, while lowest in ADC, which was 29.68%. The incidence of lung cancer in male was significantly higher that that of female, with a sex ratio of 2.04∶1. The highest sex ratio was observed in SCC, which was 9.14∶1, while lowest in ADC, which was 1.14∶1. The distribution of histological subtypes in male lung cancer patients was consistent with the general situation.While among the female lung cancer patients, the proportion of ADC was the highest (75.42%), followed by SCC (10.08%), squamous cell carcinoma (7.34%) and large cell carcinoma (0.39%). Analyzed by the birth cohort, the proportion of ADC gradually increased with the age, while the reduced tendency was observed in SCC (P<0.000 1). Conclusion: Adenocarcinoma is the most important histological subtype of lung cancer, and the distribution characteristics of histological subtypes of lung cancer differs among genders, age and birth cohort.

RESUMO

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.

RESUMO

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.

RESUMO

Objective: From the economic point of view, this study was to systematically assess the status quo on lung cancer screening in the world and to provide reference for further research and implementation of the programs, in China. Methods: PubMed, EMbase, The Cochrane Library,CNKI and Wanfang Data were searched to gather papers on studies related to economic evaluation regarding lung cancer screening worldwide, from the inception of studies to June 30(th), 2018. Basic characteristics, methods and main results were extracted. Quality of studies was assessed. Cost were converted to Chinese Yuan under the exchange rates from the World Bank. The ratio of incremental cost-effectiveness ratio (ICER) to local GDP per capita were calculated. Results: A total of 23 studies (only 1 randomized controlled trial) were included and the overall quality was accepted. 22 studies were from the developed countries. Nearly half of the studies (11 studies) took 55 years old as the starting age of the screening program. Smoking history was widely applied for the selection of criteria on target populations (18). Low-dose computed tomography (LDCT) was involved in every study used to evaluate the economic effectiveness. Annual (17) and once-life time (7) screening were more common frequencies. 22 studies reported ICERs for LDCT screening, compared to no screening, of which 17 were less than 3 times local GDP per capita, and were considered as cost-effectiveness, according to the WHO's recommendation. 15 and 7 studies reported ICERs for annual and once-life time screening, of which 12 and 7 studies were in favor the results of their cost-effectiveness, respectively. Additionally, the cost-effectiveness of once-lifetime screening was likely to be superior to the annual screening. Differences of cost-effectiveness among the subgroups, by starting age or by the smoking history, might exist. Conclusions: Based on the studies, evidence from the developed countries demonstrated that LDCT screening programs on lung cancer, implemented among populations selected by age and smoking history, generally appeared more cost-effective. Combined with the local situation of health resource, the findings could provide direction for less developed regions/countries lacking of local evidence. Low frequency of LDCT screening for lung cancer could be adopted when budget was limited. Data on starting ages, smoking history and other important components related to the strategy of screening programs, needs to be precisely evaluated under the situation of local population.

RESUMO

Objective: To estimate the incidence and mortality of kidney cancer in China in 2014, based on the cancer registration data. Data was collected through the National Central Cancer Registry (NCCR). Methods: All together, 449 cancer registries submitted required data on incidence and deaths of kidney cancer occurred in 2014, to the NCCR. After evaluation on the quality of data,339 registries were accepted for analysis and stratified by areas (urban/rural) and age groups. Combined with data from the National population in 2014, the nationwide incidence and mortality of kidney cancer were estimated. Data from the 2000 National census was used, and with Segi's population used for the rates of age-standardized incidence/mortality. Results: The qualified 339 cancer registries covered a total population of 288 243 347, with 144 061 915 in urban and 144 181 432 in rural areas. The percentage of morphologically verified cases and cases with only available death certificates were 72.70% and 1.27%, respectively. The mortality to incidence ratio was 0.37. The estimates of new cases were around 68 300 in whole China, in 2014, with a crude incidence rate as 4.99/100 000 (95%CI: 4.95/100 000-5.03/100 000). The age-standardized incidence rates of kidney cancer, estimated by China standard population (ASR China) and world standard population (ASR world) were 3.43/100 000 (95%CI: 3.40/100 000-3.46/100 000) and 3.40/100 000 (95%CI: 3.37/100 000- 3.43/100 000), respectively. The cumulative incidence rate of kidney cancer was 0.40% in China. The crude and ASR China incidence rates for males appeared as 6.09/100 000 (6.03/100 000-6.15/100 000) and 4.32/100 000 (4.28/100 000-4.36/100 000), respectively, whereas those were 3.84/100 000 (3.79/100 000-3.89/100 000) and 2.54/100 000 (2.50/100 000-2.58/100 000) for females. The crude and ASR China incidence rates in urban areas appeared as 6.60/100 000 (95%CI: 6.54/100 000-6.66/100 000) and 4.25/100 000 (95%CI: 4.21/100 000-4.29/100 000), respectively, whereas those were 3.05/100 000 (95%CI: 3.01/100 000-3.09/100 000) and 2.29/100 000 (95%CI: 2.25/100 000-2.33/100 000) in rural areas. The estimates of kidney cancer deaths were around 25 600 in the country, in 2014, with a crude mortality rate of 1.87/100 000 (95%CI: 1.85/100 000-1.89/100 000). The ASR China and ASR world mortality rates appeared as 1.16/100 000 (95%CI: 1.14/100 000-1.18/100 000) and 1.16/100 000(95%CI: 1.14/100 000-1.18/100 000), respectively, with a cumulative mortality rate (0-74 years old) of 0.12%. The crude and ASR China mortality rates were 2.31/100 000 (95%CI: 2.27/100 000- 2.35/100 000) and 1.52/100 000 (95%CI: 1.50/100 000-1.54/100 000) for males, respectively, whereas those were 1.41/100 000 (95%CI: 1.38/100 000-1.44/100 000) and 0.81/100 000 (95%CI: 0.79/100 000- 0.83/100 000) for females. The crude and ASR China mortality rates were 2.49/100 000 (95%CI: 2.45/100 000-2.53/100 000) and 1.42/100 000 (95%CI: 1.40/100 000-1.44/100 000) in urban areas, respectively, whereas those were 1.12/100 000 (95%CI: 1.09/100 000-1.15/100 000) and 0.78/100 000 (95%CI: 0.76/100 000-0.80/100 000) in the rural areas. Conclusions: Both the incidence and mortality of kidney cancer seemed low, in China. However, the incidence of kidney cancer had greatly increased. Our findings suggested that prevention and control strategies for kidney cancer should be focused on males in the urban areas.

RESUMO

Objective: To estimate lung cancer incidence and mortality in China using population-based cancer registry data in 2014 collected by National Central Cancer Registry of China (NCCRC). Methods: 449 cancer registries submitted cancer registry data in 2014. All datasets were evaluated and 339 registries' data which met the quality control criteria of NCCRC were analyzed. Numbers of new lung cancer cases and deaths were estimated using calculated incidence and mortality rates and corresponding national population stratified by areas, sexes and age groups. The standard population of Chinese census in 2000 and world Segi' s population were applied to calculate age-standardized incidence and mortality rates in China and worldwide, respectively. Results: A total of 781, 500 new lung cancer cases were diagnosed in 2014. The crude incidence rate was 57.13 per 100 000 and the age-standardized incidence rates by Chinese standard population (ASIRC) and by world standard population (ASIRW) were 36.71 per 100 000 and 36.63 per 100 000, respectively. The cumulative incidence rate (0-74 years old) was 4.50%. Lung cancer was the most common cancer in male (ASIRW: 50.04 per 100 000) and the second most common cancer in female (ASIRW: 23.63 per 100 000). The incidence rates were slightly similar in urban areas and in rural areas (ASIRW: 36.64 per 100 000 vs 36.56 per 100 000). A total of 626 400 lung cancer deaths were reported. The crude mortality rate was 45.80 per 100 000 and the age-standardized mortality rates by Chinese standard population (ASMRC) and by world standard population (ASMRW) were 28.49 per 100 000 and 28.31 per 100 000, respectively. The cumulative mortality rate (0-74 years old) was 3.32%. Lung cancer was the most common cause of cancer deaths both in male (ASMRW: 40.21 per 100 000) and female (ASMRW: 16.88 per 100 000). The mortality rate was slightly higher in rural areas than in urban areas (ASMRW: 28.63 per 100 000 vs 28.04 per 100 000). Both lung cancer incidence and mortality rates increased with age, and the peak age was 80-84 years group. Conclusions: The disease burden of lung cancer is heavy in China. Efficient national health policies and prevention and control strategies against lung cancer should be promoted.

RESUMO

Objective: To estimate the incidence and mortality of laryngeal cancer in China based on the cancer registration data in 2014, collected by the National Central Cancer Registry (NCCR), and to provide support data for the control and prevention of laryngeal cancer. Methods: The incident and death data of laryngeal cancer in 2014 from 339 cancer registries met the quality criteria of NCCR, and then adopted for analysis. The incident and death number, crude rate, age standardized rate, truncated rate and proportion which stratified by areas (urban/rural) and age were calculated. The nationwide incidence and mortality of laryngeal cancer in 2014 were estimated by combining with those data on national population in 2014. Chinese population census in 2000 and Segi's population were used for age-standardized incidence/mortality rates. Results: It was estimates that 23.4 thousand new cases of laryngeal cancer occurred in China in 2014. There were 20.8 thousand males and 2.6 thousand females. And 14.5 thousand occurred in urban areas, while 8.9 thousand in rural areas. The age standardized rates of incidence by world standard population (ASRs world) in male, female and both genders were 2.05/100, 000, 0.24/100, 000 and 1.14/100, 000, respectively, whereas those were 1.22/100, 000 and 1.03/100, 000 for urban and rural areas. The incidence was much higher in males than females, and slightly higher in urban areas than those in rural areas. Moreover, it was estimates that 13.2 thousand death cases of laryngeal cancer occurred in China in 2014. There were 11.5 thousand males and 1.7 thousand females. And 7.8 thousand occurred in urban areas, while 5.4 thousand in rural areas. The age standardized rates of mortality by ASRs world in male, female and both genders were 1.08/100, 000, 0.14/100, 000 and 0.60/100, 000, respectively, whereas those were 0.60/100, 000 and 0.59/100, 000 for urban and rural areas. The mortality was much higher in males than females, and slightly higher in urban areas than those in rural areas. In males, the age specific incidence and mortality of laryngeal cancer increased greatly from 40-44 and 45-44 years old, respectively, and peaked at age group of 75-79 and >85 years old. In females, the age specific incidence and mortality increased slowly from 50-54 and 60-64 years old, respectively, and peaked at age group of 80-84 and >85 years old. The trends remained similar in urban and rural areas, except for the different peak ages. Conclusions: The incidence and mortality of laryngeal cancer in China are at middle-low levels worldwide, and there are obvious differences between urban and rural areas with distinct gender disparity. Comprehensive prevention and control strategies should be carried out according to local status and age groups.

RESUMO

Objective: To estimate the incidence and mortality of bladder cancer in China based on the cancer registration data in 2014, collected by the National Central Cancer Registry (NCCR). Methods: There were 449 cancer registries submitted bladder cancer new cases and deaths occurred in 2014 to NCCR. After evaluating the data quality, 339 registries' data were finally accepted for analysis. According to the national population data of 2014, the nationwide incidence and mortality of bladder cancer were estimated by stratification in the area (urban or rural), gender, and age. Chinese population census in 2000 and Segi's population were used for age-standardized incidence/mortality rates. Results: All 339 cancer registries covered a total of 288 243 347 populations (144 061 915 in urban and 144 181 432 in rural areas). The percentage of morphologically verified cases and death certificate-only cases were 74.86% and 1.45%, respectively. The mortality to incidence ratio was 0.41. The estimates of new bladder cancer cases were 78 100 in China in 2014, with a crude incidence rate of 5.71/100 000. The age-standardized incidence rates by China standard population (ASR China) and world standard population (ASR world) of bladder cancer were 3.61/100 000 and 3.56/100 000, respectively. Cumulative incidence rate of bladder cancer in China was 0.41%. The crude and ASR China incidence rates in urban areas were 6.88/100 000 and 4.07/100 000, respectively, whereas those were 4.29/100, 000 and 2.96/100 000 in rural areas. The estimates of bladder cancer deaths caused by bladder cancer were about 32 100 in China in 2014, with a crude mortality rate of 2.35/100 000. The ASR China and ASR world mortality rates were both 1.30/100 000 with a cumulative mortality rate (0-74 years old) of 0.12%. The crude and ASR China mortality rates were 2.79/100 000 and 1.41/100 000 in urban areas, respectively, whereas those were 1.81/100 000 and 1.14/100 000 in rural areas. Conclusions: The incidence and mortality pattern of bladder cancer were different in urban and rural areas. The incidence and mortality were higher in urban areas than that in rural areas, and higher for male than for female. We should focus on strengthening the prevention and control of bladder cancer in key population, especially men in urban areas.
