RESUMEN
Objective: To analyze the detection of colorectal advanced neoplasms in the population who underwent colonoscopy screening in Henan Province as part of the Urban China Cancer Screening Program and its influencing factors. Methods: A cross-sectional study design was employed. Based on the Cancer Screening Program conducted in Henan Province, the study enrolled 7 454 urban residents who manifested no symptoms and were recruited from eight cities in the province, including Zhengzhou, Zhumadian, Anyang, Luoyang, Nanyang, Jiaozuo, Xinxiang, and Puyang from October 2013 to October 2019, and participated in colonoscopy screening. The χ2 test was used to compare the detection rates of colorectal advanced neoplasms among participants with different characteristics, and a multivariate logistic stepwise regression model was used to analyze the factors affecting the detection rates. Results: A total of 7 454 subjects underwent colonoscopy screening, and 112 cases of colorectal advanced neoplasms were detected. Multivariate logistic regression analysis suggested that older age, smoking, higher meat intake, history of diabetes, and family history of colorectal cancer in a first-degree relative were risk factors for colorectal advanced neoplasms. The detection rate was significantly higher in people aged 60-74 years compared with those aged 40-49 years, with an odds ratio (OR) of 2.04 (95% CI: 1.23-3.38).The rates were higher in people who smoked than those who did not smoke, with an OR of 2.21 (95% CI: 1.48-3.31), and in people who consumed more meat than those who consumed less, with an OR of 1.53 (95% CI: 1.04-2.26). Those with diabetes had a higher detection rate compared with those without, with an OR of 1.69 (95% CI: 1.07-2.69), and those with a first-degree family history of colorectal cancer had a higher detection rate than those without, with an OR of 1.64 (95% CI: 1.09-2.46). Conclusion: The detection rate of colorectal advanced neoplasms through colonoscopy screening in Henan Province covered by the Urban China Cancer Screening Program is 1.50%. Older age, smoking, higher meat intake, history of diabetes, and family history of colorectal cancer in a first-degree relative are identified as risk factors for colorectal advanced neoplasms.

High-risk human papillomavirus (HPV)-related cancers consist of cervical cancer, anal cancer, penile cancer, vulvar cancer, vaginal cancer, and head and neck cancer (HNC). Of these, the disease burden of HNC is second only to cervical cancer. HNC mostly originates from malignant lesions of squamous epithelial cells and mainly includes oral cavity cancer, pharyngeal cancer (including nasopharyngeal cancer, oropharyngeal cancer, and hypopharyngeal cancer), and laryngeal cancer. Tobacco use, alcohol abuse, and HPV infection are three primary risk factors. Recently, there is an upward trend of HNC incidence globally, especially in high-income countries. In China, the disease burden and trends of HPV-related HNC are still not clear. A few small sample size and single-center studies suggest a high HPV prevalence and increasing trend in HNC. Methodological differences in HPV testing and regional variabilities still exist among these studies. Among the anatomic sites, oropharyngeal cancer has been shown to be caused by HPV infection, but the association of HPV with other sites is still under debate. In addition, there is a paucity of relevant studies. Here, this review narrates the association between HPV infection and HNC, compares the differences between global and Chinese studies, and then explores the importance of HPV infection in various anatomical sites. The main objective is to highlight the research on HPV-related HNC and promote relevant prevention and treatment programs.

Objective: To investigate the clinical features, morphological characteristics, immunophenotype, and differential diagnosis of goblet cell adenocarcinoma (GCA) in the digestive system. Methods: The clinicopathological data, morphological characteristics, immunophenotypes of 22 cases of GCA in the digestive system diagnosed from January 2010 to January 2021 were collected. Meanwhile, 25 cases of neuroendocrine neoplasm (NEN) and 24 cases of adenocarcinoma were used as controls. Relevant literature was also reviewed. Results: There were 16 males and 6 females, aged from 36 to 79 years with an average of 56 years. The anatomical sites of the 22 GCA were mostly appendix (17 cases) and occasionally extra-appendix (5 cases), including 3 cases in stomach, 1 case in duodenum and 1 case in anal. All 17 cases of appendiceal GCA were pure GCA. Among the 5 cases of extra-appendiceal GCA, One case of gastric GCA was pure, two cases of gastric GCA with NEN or adenocarcinoma, duodenal GCA with NEN and adenocarcinoma, anal GCA with NEN.Low-grade GCAs were composed of goblet, Paneth and neuroendocrine cells, which were arranged in intestinal crypt tubular or cluster structures and distributed in the wall of digestive system. The tubular and cluster structures lacked adhesion. Goblet cells were columnar, located in the base, with clear cytoplasm, small nuclei, inconspicuous atypia, and uncommon mitoses. Extracellular mucus and signet-ring cells with nuclear variations could be seen in some cases. Nerve fiber bundle invasion and tumor thrombus in vessels were often present. High-grade GCAs lacked tubular and cluster structures, and their histological structures were more complex. Tumor cells expressed mixed neuroendocrine and glandular epithelial markers. Similar to the expression patterns of synaptophysin and chromogranin A, CD200 and INSM1 were also dot-like or patch-positive in GCA. Conclusions: GCA is an infrequent tumor of the digestive system and shows the bi-directional differentiation characteristics of neuroendocrine and glandular epithelium. Accurate diagnosis and staging are related to its prognosis.

Objective: To estimate the incidence and mortality of esophageal cancer in 2016 and their changing trend during 2010-2016 according to the cancer registration data in Henan province. Methods: The data quality including completeness, validity, and reliability of local registries which submitted the cancer registration data of 2016 were assessed according to the criteria of Guideline on Cancer Registration in China and IARC/IACR. Esophageal cancer cases (ICD10: C15) were extracted from the database, and the incidence and mortality stratified by gender, age, and areas (urban/rural) were calculated, the incidence and mortality of provincial cancer were estimated combined with provincial population data. China's 2000 census population and Segi's population were used to calculate the age-standardized rate. Joinpoint model was used to estimate the changing trend of age standardized incidence and mortality along with the calendar year. Results: Approximately 40.10 thousand new esophageal cancer cases were diagnosed in Henan in 2016, accounting for 13.46% of all new cancer cases, and it ranked the third among cancer of all sites. The crude incidence of esophageal cancer was 37.21/100 000 with an age-standardized incidence rate by China standard population (ASIRC) of 26.74/100 000 and an age-standardized incidence rate by world standard population (ASIRW) of 27.12/100 000. The incidence of esophageal cancer in males was higher than that in females, with the ASIRC of 34.53/100 000 and 19.19/100 000, respectively. It was higher in rural areas than that in urban areas, with the ASIRC of 28.13/100 000 and 20.90/100 000, respectively. About 29.30 thousand deaths of esophageal cancer in Henan in 2016, accounting for 15.61% of all cancer deaths in Henan, which ranked the third among cancer of all sites. The crude mortality rate was 27.14/100 000 with an age-standardized mortality rate by China standard population (ASMRC) of 18.74/100 000 and an age-standardized mortality rate by world standard population (ASMRW) of 18.78/100 000. The mortality in males was higher than that in females, with the ASMRC of 24.78/100 000 and 13.12/100 000, respectively. It was also higher in rural areas than that in urban areas, with the ASMRC of 19.48/100 000 and 15.73/100 000, respectively. The ASIRC and ASMRC were declining with annual percent change (APC) of 3.12% (APC=-3.12%; 95%CI: -5.30%, -0.90%; P=0.015) and 2.47% (APC=-2.47%; 95%CI: -4.70%, -0.20%; P=0.039) during 2010-2016. However, the significant declining trend was only observed in rural areas in Henan, and the changing trend was same between males and females. Conclusions: The incidence and mortality of esophageal cancer are declining since 2010, however, the disease burden remains large in Henan. Therefore, comprehensive prevention and control efforts should be strengthened according to its epidemic characteristics and risk factors.

Objective: To estimate stomach cancer incidence and mortality in Henan, 2016 and analyze the trend of stomach cancer incidence and mortality from 2010 to 2016. Methods: Stomach cancer related data in 2016 was extracted from Henan cancer registration and follow-up system. All data were qualified in validity, reliability and completeness according to the Guideline on Cancer Registration in China and International Agency for Research on Cancer (IARC/IACR). The incidence and mortality of stomach cancer were estimated by areas, gender and age based on the quality data and the registered population data of Henan province in 2016. The epidemic trend of stomach cancer was also been evaluated based on the age-standardized incidence and mortality by Chinese population (ASR China) from 2010 to 2016. Results: In 2016, the estimated incident cases of stomach cancer were 44 311. The incidence was 41.07/100 000, ASR China was 30.17/100 000, ASR by world population (ASR world) was 30.36/100 000, and the cumulative incidence rate was 3.84%. The incidences of male and female were 55.65/100 000 and 25.35/100 000, respectively. Meanwhile, 32 927 people died of stomach cancer in Henan. The mortality was 30.52/100 000, ASR China was 21.45/100 000, ASR world was 21.54/100 000, and the cumulative mortality was 2.53%. From 2010 to 2016, both the ASR China for incidence and mortality of stomach cancer in Henan showed a steady downward trend. In rural, the ASR China for incidence and mortality decreased rapidly, while the stable trend was observed in urban. Nevertheless, the incidence and mortality of stomach cancer in rural were still higher than those in urban. Conclusions: The incidence and mortality of stomach cancer in Henan province showed steadily declining trend from 2010 to 2016, and the geographical distribution difference between rural and urban areas was gradually narrowing. However, the disease burden was still high in 2016.

Objective: To systematically evaluate the methodological quality of screening guidelines for upper gastrointestinal cancer (including esophageal cancer and gastric cancer) both at home and abroad, and provide reference for the update of upper gastrointestinal cancer screening guidelines in China. Methods: Original articles and grey literature published as of 31th Aug 2020 were retrieved using Chinese databases (CNKI, Wanfang, China Biomedical Literature Database and China Guideline Clearinghouse), PubMed, The Cochrane Library and Embase, as well as those from International Agency for Research on Cancer and the International Guide Collaboration Network. The inclusion criteria were being independent guidelines/recommendation documents for upper gastrointestinal cancer screening and meeting the definition of the institute of Medicine, USA. The exclusion criteria were being guideline abstracts, interpretation and evaluation literature, duplicate publications, updated original guidelines, and clinical treatment or practice guidelines for esophageal or gastric cancer. Appraisal of Guidelines for Research and Evaluation (AGREE â ¡) and Reporting Items for Practice Guidelines in Healthcare (RIGHT) were used to compare and evaluate the quality and reporting standard of esophageal or gastric cancer screening guidelines. Results: A total of 6 esophageal cancer screening guidelines and 5 gastric cancer screening guidelines were included. The results of the AGREE â ¡ quality evaluation showed that the overall quality of eleven guidelines varied, including two guidelines recommended for "A", one for "B", five for "C" and three for "D". The guidelines had higher scores in the areas of scope and purpose, and clarity. The esophageal cancer screening guidelines had different scores in the areas of rigor and independence. The gastric cancer screening guidelines generally had low scores in the areas of participants and application. The RIGHT evaluation results showed that the quality of eleven guidelines should be improved. The six items with poor report quality were background, evidence, recommendations, review and quality assurance, funding and conflict of interest statement and management and others. Conclusion: The quality of the included upper gastrointestinal cancer screening guidelines is general, and the standardization needs to be strengthened.

Objective: To evaluate the performance of high risk human papilloma virus (HR-HPV) E6/E7 mRNA in triaging women with atypical squamous cells of undetermined signification (ASCUS). Methods: The ASCUS cohort determined by liquid-based cytology test in the cervical cancer screening queue in Luoshan County, Xinyang City, Henan Province 2017 were selected. The population underwent colposcopy biopsy and pathological tests, combined with HPV16 or 18 (HPV16/18), HR-HPV DNA and HPV E6/E7 mRNA test. By using the pathological result as the gold standard, the sensitivity, specificity, positive predictor (PPV), negative prediction (NPV), referral rate and 95% confident interval (CI) of HPV E6/E7 mRNA, HR-HPV DNA, HPV16/18 were calculated, respectively. Results: The average age of 312 ASCUS women was 52.6±7.3 years old. Among the 290 women diagnosed as normal by pathology, 64 (22.1%) were HPV E6/E7 mRNA positive, 86 (29.7%) were HR-HPV DNA positive, and 19 (6.6%) were HPV16/18 positive. All of the cervical intraepithelial neoplasia (CIN) cases determined by pathology were both HPV E6/E7 mRNA and HR-HPV DNA positive. The sensitivity, specificity, PPV, NPV and referral rate of HPV E6/E7 mRNA for predicting CIN2+ lesion in women with ASCUS were 100.0% (95%CI: 72.3, 100.0), 77.8% (95%CI: 72.8, 82.1), 13.0% (95%CI: 7.2, 22.3), 100.0% (95%CI: 98.4, 100.0) and 24.7%. Compared with HPV E6/E7 mRNA, the sensitivity of HR-HPV DNA was similar with HPV E6/E7 mRNA, but with a lower specificity [70.2% (95%CI: 64.8, 75.1), P<0.05], a higher referral rate (32.1%, P<0.05); while HPV 16/18 had a high specificity (93.4%, 95%CI: 90.0, 95.7) and a low sensitivity (30.0%, 95%CI: 10.8, 60.3). Based on the age stratification by age 45, the sensitivity of HPV E6/E7 mRNA in both age groups was 100.0%. The specificity of HPV E6/E7 mRNA in group of ≥45 years was a little higher than that in group of <45 years [79.0% (95%CI: 73.7, 83.5) versus 68.3% (95% CI: 53.0, 80.4)], but the difference was not statistically significant (P>0.05). Conclusions: The ASCUS woman triaging effect of HPV E6/E7 mRNA detection is better than those of HR-HPV and HPV16/18 under certain conditions. The application of HPV E6/E7 mRNA detection to triage ASCUS population can avoid unnecessary colposcopy referral and reduce the missed diagnosis of cervical lesions.

Objective: To analyze the effects of esophageal cancer screening in Henan rural areas with cancer screening program from 2014 to 2018. Methods: From July 2014 to June 2019, according to the National Early Diagnosis and Treatment of Upper Gastrointestinal Cancer in Rural Areas Project, cluster sampling method was adopted in 16 counties/county-level cities in rural areas with high incidence of esophageal cancer in Henan province. Endoscopic iodine staining and indicative biopsy were used to screen esophageal cancer. The patients with mild and moderate dysplasia confirmed in screening were followed up. The distribution of esophageal diseases in the screening population was calculated, and Chi-square test was used to compare the differences of detection rate and early diagnosis rate between the primary screening population and the follow-up population. Results: The age of 116 630 primary screening population was (54.29±7.70) years old, and the proportion of males was 41.2% (48 108). In the primary screening population, patients with normal esophagus, mild to moderate dysplasia, severe dysplasia and above accounted for 92.91% (108 363), 6.03% (7 035) and 1.06% (1 232), respectively. The detection rate of esophageal cancer was 1.06% (1 232/116 630), and the rate of early diagnosis was 85.80% (1 057). Among the follow-up population of 6 154 people, those with normal esophagus, mild to moderate dysplasia, severe dysplasia and above diseases accounted for 63.45% (3 905), 33.13% (1 519) and 3.41% (210), respectively. The detection rate of esophageal cancer was 3.41% (210/6 154), and the rate of early diagnosis was 91.90% (1 939). Compared with the primary screening population, the risk of esophageal cancer was higher in the overall follow-up population, people either with mild or with moderate dysplasia diagnosed in primary screening, with OR values (95%CI) of 3.23 (2.78, 3.75), 1.85 (1.49, 2.29) and 8.13 (6.69, 9.88), respectively. Conclusion: From 2014 to 2018, in the early diagnosis and early treatment of upper digestive tract cancer project in rural areas of Henan Province, the detection rate of the follow-up population is significantly higher than that of the primary screening population. Improving follow-up rate and paying more attention to the screening of people who need follow-up could further improve the screening effect.

Objective: To evaluate the compliance of colonoscopy screening and the detection rate of colorectal lesions with colonoscopy in urban areas of Henan province from 2013 to 2019. Methods: The study objects were derived from the Cancer Screening Program in Urban Henan Province, China. From October 2013 to October 2019, 282 377 residents, who had lived in the local area for more than three years, were recruited from Zhengzhou, Zhumadian, Anyang, Luoyang, Nanyang, Jiaozuo, Puyang and Xinxiang. The cancer risk assessment questionnaire was used to collect basic demographic characteristics, eating habits, living environment and habits, psychology and emotions, past disease history and family history of cancer, and women's physiological and reproductive history. The cancer risk assessment model was used for evaluating the risk of colorectal cancer. The data related to colonoscopy screening was obtained from the participating hospitals. Chi-square test was used to analyze the compliance rate among different groups. Results: The 282 377 subjects were (55.26±8.68) years old, of which 44.80% (126 505) were males, and 67.63% (190 694) had junior/senior/tertiary education background. A total of 39 834 (14.11%) subjects were assessed to be at high risk for colorectal cancer, of which 7 454 took the following colonoscopy screening, yielding a participation rate of 18.71%. The screening rate was higher in those aged 50 to 54 (20.42%) and 55 to 59 (20.43%) years, and lowest in those aged 70 years and older (12.30%) (P<0.001). A total of 17 colorectal cancer cases were detected, with a detection rate of 0.23% (17/7 454). Conclusion: Colonoscopy as a means of screening for colorectal cancer is helpful for early detection of colorectal lesions, but the participation rate is poor.

Objective: To evaluate the compliance rate and its impact factors of liver cancer screening for high-risk groups in urban areas of Henan Province from 2013 to 2019. Methods: Residents of 40-74 years old in 8 cities of Henan province were selected to investigate the risk factors and liver cancer risk assessment. Subjects with high risk of liver cancer received AFP combined ultrasonography for screening. Chi-square tests were used to compare the differences in liver cancer screening participation rates between groups. Multivariate logistic regression models were applied to explore the potential factors correlating to the compliance of liver cancer screening. Results: Overall, 3 6781 participants who met the inclusion criteria were included in this analysis, and 17 241 of them took the following liver cancer screening, yielding a participation rate of 46.87%. The participation rate varied greatly across cities, ranging from 62.50% to 38.59%. Moreover, the participation rate varied greatly across periods, ranging from 52.77% in 2014-2015 to 38.14% in 2013-2014. The multivariate Logistic regression analyses showed that: female, older, high education degree, cigarette and alcohol intake, infrequent physical exercise, chronic hepatitis B, chronic hepatitis C, fatty liver, gallstones and a family history of liver cancer were inclined to accept liver cancer screening (P<0.05). Conclusions: The overall participation rate of liver cancer screening among high-risk population is less than 50% in urban areas of Henan Province. Implement of effective interventions targeting the specific high-risk populations might improve the overall compliance rate of liver cancer screening in the future.

Objective: To estimate cancer incidence and mortality of kidney and unspecified urinary organs in China using cancer registry data in 2015. Methods: The cancer registry data from 501 local cancer registries in China were collected, checked and assessed based on the criteria of data quality control of the National Central Cancer Registry of China (NCCRC), and data from 368 registries were qualified for the analysis. Cancer incidence and mortality rates of kidney and unspecified urinary organs stratified by geographical location (eastern, middle, western areas), gender, age groups were calculated. Population data of 2015 was used to estimate the cancer cases and deaths of kidney and unspecified urinary organs in China. Chinese standard population in 2000 and Segi's world population were used for the calculation of age-standardized incidence and mortality rates. Results: A total of 74.2 thousand new cancer cases of kidney and unspecified urinary organs were diagnosed in 2015, 46.9 thousand of them were male, while 27.3 thousand were female, with a crude incidence rate of 5.40/10(5). The age-standardized incidence rates by Chinese (ASIRC) and world standard population (ASIRW) were 3.57/10(5) and 3.56/10(5), respectively. A total of 53.4 thousand and 20.8 thousand new cases were diagnosed in urban and rural area, with incidence rates of 6.93/10(5) and 3.45/10(5), respectively. The ASIRC of urban area was higher than that of rural area. There were 39.2 thousand, 20.6 thousand, and 14.4 thousand new cases diagnosed in eastern, middle, and western areas of China, respectively. The crude incidence rates were 7.60/10(5), 4.47/10(5), and 3.63/10(5), respectively, with a descend ASIRC of each area. A total of 27.1 thousand death cases reported, of them 16.9 thousand were male, while 10.2 thousand were female, with a crude mortality rate of 1.97/10(5), both of the ASIRC and ASMRW were 1.21/10(5). The deaths of urban and rural area were 19.5 thousand and 7.6 thousand cases, with the crude mortality rates of 2.53/10(5) and 1.26/10(5), respectively. The ASIRC of urban area was higher than that of rural area. There were 13.4 thousand, 8.4 thousand, and 5.1 thousand death cases reported in eastern, middle, and western areas, respectively, the crude mortality rates were 2.61/10(5), 1.83/10(5) and 1.30/10(5), respectively, with a descend ASIRC of each area. Conclusion: The disease burden of kidney cancer differs between urban area and rural area, and differs among eastern, middle, and western areas of China, therefore, different prevent and treatment strategies should be taken in different areas of China.

Objective: To evaluate the compliance of low-dose computed tomography (LDCT) screening for high-risk groups of lung cancer and influencing factors in urban area of Henan province during 2013-2017. Methods: Cluster sampling method was used to select the residents of 40-74 years old in Henan for cancer risk factor investigation and lung cancer risk assessment. Subjects with high risk of lung cancer received LDCT screening. The differences of LDCT receiving rates between groups were compared with χ(2) tests, and the time trend of rates were tested with the Cochran- Armitage trend test. The potential factors correlating to the compliance of LDCT screening were identified with multivariate logistic regression models. Results: Overall, 35 672 participants who met the inclusion criteria were included in this analysis, and 13 383 of them received LDCT screening, the receiving rate was 37.52%. The receiving rate varied greatly across cities, ranging from 38.47% to 26.73% (P<0.05). Moreover, the receiving rate varied greatly across periods, ranging from 29.22% during 2013-2014 to 43.30% during 2014-2015, and the receiving rate increases gradually as the screening year increases (P<0.001). The multivariate logistic regression analyses showed that: being female, age 45-69 years, with education level of junior high school/high school, previous smoking, drinking or previous drinking, infrequent physical exercise, history of tuberculosis, history of chronic bronchitis, history of emphysema, history of asthma bronchiectasis and family history of lung cancer were positive factors for receiving LDCT screening (All P<0.05). Conclusions: The overall compliance of LDCT screening in high-risk population of lung cancer was still not high in urban area of Henan. Implementation of effective interventions targeting the specific high-risk populations might improve the overall compliance of LDCT screening in the future.

Cervical cancer is the fourth common cancer in women globally, with the number of new cases accounted for 18.6% among all the cancer patients, in China. It is well known that the situation of prevention and control programs are quite challenging. Based on the efforts being made in the last 20 years, the etiology and carcinogenesis on cervical cancer had been clearly understood. Breakthroughs had been achieved in the development of prophylactic human papillomovirus vaccine and the technology of in screening. Various screening strategies are already available in areas with different economic status. Nevertheless, the capacity of health care services at the primary care clinics needs to be improved to narrow the gap between the reality and the demands.

Objective: To evaluate the performance of High-risk HPV typing detection in cervical cancer screening. Methods: A total of 3 231 women were recruited as the subjects of cervical cancer screening from Jiyuan city of Henan provinces from June to July 2017. All women underwent HPV DNA test. The women with cytological examination ≥ASCUS or cytological examination negative and HPV 16/18 positive underwent colposcopy biopsy and pathological examination. Pathological diagnosis was used as the gold standard. Sensitivity, specificity, positive predictive value (PPV), negative predictive value(NPV) as well as corresponding 95% confidence interval (CI) of HR-HPV and HPV 16/18 were calculated. Results: The mean age of 3 231 subjects selected in this study was 46.84±10.00 (21-64) years old. 524 subjects had the positive results of HR-HPV, including 91 of HPV16 and 15 of HPV18. Pathological test result CIN2+ was the gold standard. The sensitivity and specificity of HR-HPV for cervical precancer lesions screening were 93.75 (95%CI: 79.85-98.27) and 84.56% (95%CI: 83.26-85.77), respectively. To compared with HR-HPV, HPV16/18 had low sensitivity (65.63%, 95%CI: 48.31-79.59)and higher specificity (97.44%, 95%CI: 96.83-97.93). After age stratification by age 30 and 45, the sensitivity of HPV 16/18 was same with HR-HPV (100%, 95%CI: 34.24-100.00), the specificity of HPV 16/18 was higher than HR-HPV (98.71%, 95%CI: 96.27-99.56 vs 84.48%, 95%CI: 79.27-88.58) in<30 age group.The sensitivity of HR-HPVin 30-45 and ≥45 age group were higher than HPV16/18 (85.71%, 95%CI: 48.69-97.43 vs 71.43%, 95%CI: 35.89-91.78, 95.65%, 95%CI: 79.01-99.23 vs 60.87%, 95%CI: 40.79-77.84), but the specificity werelower than HPV16/18 (86.89%, 95%CI: 84.58-88.90 vs 98.51%, 95%CI: 97.51-99.11ã83.49%, 95%CI: 81.81-85.04 vs 96.80%, 95%CI: 95.94-97.48). Conclusions: HR-HPV detection has relatively high sensitivity and specificity in cervical cancer screening. For >30 years old women, HR-HPV is more recommended in cervical cancer screening. Therefore, HR-HPV detection is an effective method for cervical cancer screening.

Objective: To study the compliance of endoscopic screening for high-risk population of upper gastrointestinal cancer and relevant factors in urban areas of Henan Province, 2013-2017. Methods: The study participants were from the Cancer Screening Program in Urban Henan Province, China. From October 2013 to October 2017, 43 423 residents, who were evaluated as high-risk population for upper gastrointestinal cancer, were recruited from Zhengzhou, Zhumadian and Anyang. The cancer risk assessment questionnaire was used to collect basic demographic characteristics, dietary habits, living environment and habits, psychology and emotions, disease history and family history of cancer, and women's physiological and reproductive history. The data of endoscopic screening was obtained from hospitals participating in the Cancer Screening Program. Multivariate logistic regression model was applied to explore potential factors related to the compliance of endoscopic screening. Results: The age of study participants was(55.49±8.15) years old, and 44.00% (19 105) were male. About 18.41% of study subjects (7 996) took the endoscopic screening. The multivariate logistic regression analysis showed that females, individuals aged 45-64 years old, with junior high school education or above, unmarried/divorced/widowed, previous smoking, alcohol drinking, infrequent physical exercise, history of reflux esophagitis, history of superficial gastritis, history of gastric ulcer, history of duodenal ulcer, history of gastric polyps and family history of upper gastrointestinal cancer were more likely to accept endoscopic screening. Conclusion: The overall participation rate of endoscopic screening among high-risk population of upper gastrointestinal cancer was still low in urban areas of Henan Province. Gender, age, education, marital status, smoking, alcohol consumption, physical activity, history of upper gastrointestinal disease and family history of upper gastroin testinal cancer were associated with the compliance of endoscopic screening.

Objective: To evaluate the performance of Hybribio human papillomavirus (HPV) typing test kit for high risk HPV-DNA typing detection in screening of cervical precancer lesions. Methods: A total of 9 914 women were recruited in Henan, Shanxi, and Guangdong provinces from June to July 2017. All women underwent HPV DNA test. The women who diagnosed as HPV positive and cytological examination ≥ atypical squamous cells of undetermined significance (ASCUS) or HPV negative and cytological examination≥low-grade squamous intraepithelial lesions (LSIL) underwent colposcopy biopsy and pathological examination. Using the pathological diagnosis as the gold standard, the sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and 95% confidence interval (CI) of high-risk HPV and HPV16/18 tests were calculated. Results: The mean age of 9 914 subjects was (45.0±9.3) years old. Among them, 1 302 subjects were detected as high risk HPV positive, including 211 of HPV16 positive and 64 of HPV18 positive. According to the pathological gold standard of cervical intraepithelial neoplasia grade 2 (CIN2) or worse, the sensitivity and specificity of high risk-HPV and HPV 16/18 for triaging ASCUS women were 90.6% (95%CI: 75.8%-96.8%) and 78.0% (95%CI: 74.5%-81.2%) as well as 56.3% (95%CI: 39.3%-71.8%) and 95.7% (95%CI: 93.8%-97.1%), respectively. The sensitivity and specificity of high risk-HPV and HPV 16/18 for cervical precancer lesions screening were 95.1% (95%CI: 88.1%-98.1%) and 87.6% (95%CI: 86.9%-88.2%) as well as 65.9% (95%CI: 55.1%-75.2%) and 97.8% (95%CI: 97.5%-98.1%), respectively. Conclusions: The Hybribio HPV test kit has a relative high sensitivity and specificity for cervical precancer lesions screening and ASCUS triaging. It is reliable for HPV DNA detection and cervical cancer screening.

Objective: To evaluate the efficacy of lung cancer screening in urban areas of Henan province by low-dose computed tomography (LDCT) from 2013 to 2017. Methods: A cluster sampling method was used to select the residents of 40-74 years old in Henan province to investigate the risk factors and conduct lung cancer risk assessment. Subjects with high risk of lung cancer received LDCT for screening. Results: A total of 179 002 residents completed the lung cancer risk assessment, and 35 672 subjects were identified as high risk of lung cancer, with a high risk rate of 19.93%. A total of 13 383 subjects with high risk received LDCT, and the screening rate was 37.52%. There were 786 cases diagnosed as positive nodules, and the detection rate was 5.87%. Among them, 755 cases of solid/partial solid nodule were ≥5 mm, 23 cases of non-solid nodules were ≥8 mm, 8 cases were intratracheal nodules, and 115 cases were diagnosed as suspicious lung cancer. The detection rate in males was 6.74%, which was higher than 5.02% in females. The detection rate was positively related with age (P<0.05). Conclusions: The application of LDCT is a useful screening method which can elevate the early detection rate of positive nodules and other related diseases in lungs. In the future, males and older populations should be paid more attention to improve screening efficacy.

Objective: This study aimed to evaluate the clinical performance of p16/Ki-67 dual staining for triage high risk HPV (HR-HPV) infected women. Method: Target objects were women who infected HR-HPV and received colposcopy examination between April and December of 2016 at the Second Affiliated Hospital of Zhengzhou University. Gynecologists collected the cervical exfoliated cells from eligible women for p16/Ki-67 dual staining, LBC testing and HPV DNA testing. Histology diagnosis were used as gold standard. Sensitivities, specificities, positive predictive values (PPVs), negative predictive values (NPVs) of p16/Ki-67 dual staining, LBC testing and HPV16/18 testing for triage of HR-HPV positive population were calculated and compared. Results: A total of 295 HR-HPV infected women were selected, and the mean age was (44.29±11.48) years old. Positive rates of p16/Ki-67 dual staining, HPV16/18 testing and LBC testing were 70.17% (207), 56.95% (168) and 85.76% (253), respectively. When CIN2+as the endpoint, among the three triage methods, sensitivity of p16/Ki-67 dual staining was 90.00% (95%CI: 85.06%-93.43%), higher than the value of HPV 16/18 testing, but lower than the value of LBC testing. Specificity, PPV and NPV of p16/Ki-67 dual staining were the highest [71.58% (95%CI: 61.81%-79.67%), 86.96% (95%CI:81.69%-90.88%) and 77.27% (95%CI: 67.49%-84.78%)]. When detection for CIN3+, sensitivity of p16/Ki-67 dual staining was 92.90% (95%CI: 87.74%-95.99%), lower than the value of LBC testing, but higher than the value of HPV16/18 testing. Specificity of p16/Ki-67 dual staining was 55.00% (95%CI: 46.74%-63.00%), lower than the value of HPV16/18 testing, but higher than the value of LBC testing. PPV of p16/Ki-67 dual staining was 69.57% (95%CI: 62.99%-75.43%), lower than the value of HPV 16/18 testing, but higher than the value of LBC testing. NPV of p16/Ki-67 dual staining was 87.50% (95%CI: 78.99%-92.87%), higher than value of HPV 16/18 testing, but lower than the value of LBC testing. Conclusion: p16/Ki-67 dual staining has better clinical effects than HPV 16/18 testing and LBC testing for triage women with HR-HPV infection.
