Objective To analyze the prevalence and risk factors of underscreening among cervical cancer screening participants in Wuxiang County,Shanxi Province in 2019,providing evidence-based support for optimizing mobilization strategies.Methods Data from cervical cancer screening programs conducted between 2019 and 2024 in Wuxiang County were retrospectively collected.The follow-up screening behaviors of women screened in 2019 were analyzed,and factors associated with underscreening were identified.Results A total of 3759 women underwent cervical cancer screening in 2019.Among them,492 women(13.09％)with abnormal primary screening results requiring follow-up in 12 months,yet only 43(8.74％)completed;2154 women(57.30％)with negative liquid-based cytology testing(LCT)results needed re-screening after 3 years,701(32.54％)completed;1113 women(29.61％)with negative HPV/combined results needed re-screening after 5 years,734(65.95％)completed.Overall,2299 women(60.69％)exhibited underscreening.Multivariate analysis showed that underscreening was more likely among community residents than rural residents(OR=2.309,P=0.018),older women(OR=1.065,P＜0.001),those in organized screening compared to opportunistic screening(OR=3.789,P＜0.001),those undergoing LCT(OR=4.607,P＜0.001)or combined screening instead of human papillomavirus testing(OR=3.624,P＜0.001),and those with abnormal screening results(OR=6.859,P＜0.001).Conclusion Substantial proportions of cervical cancer screening participants demonstrate poor adherence to guideline-recommended screening intervals,and particularly need to focus on older women and those with abnormal screening results.Implementation of electronic screening record systems and emphasizing knowledge of periodical screening in health education could enhance compliance with"70％screening coverage"target for cervical cancer prevention.

Objective:To analyze the real-world practices of resecting sessile colorectal polyps of varying long diameters using cold forcep polypectomy (CFP), cold snare polypectomy (CSP), or endoscopic mucosal resection (EMR).Methods:A total of 12 290 nonpedunculated colorectal polyps of long diameter ≤19 mm (from 10 295 patients) were retrospectively enrolled from January 2022 to December 2023. Polypectomy was conducted by 30 endoscopists. The polyps were categorized into three groups based on long diameter: 1-5 mm, >5-10 mm and >10-19 mm, and the differences of polypectomy methods were compared in three groups. The usage of hemostatic clips in CSP among >5-10 mm polyps and the changes in resection methods between 2022 and 2023 were analyzed.Results:CFP (6 769 polyps, 81.7%) was the predominant method for resecting 1-5 mm sessile polyps (8 289 polyps). For sessile polyps sized >5-10 mm (2 455 polyps), CSP was used most (1 372, 55.9%), although its utilization varied significantly among physicians with the median usage rate of 52.9% (40.3%, 60.0%). EMR (1 349 poolyps, 87.3%) was the main method for >10-19 mm sessile polyps. The usage rate of CSP in sessile polypectomy for polyps >5-10 mm significantly increased from 45.7% (503/1 101) in 2022 to 64.2% (869/1 354) in 2023. The overall frequency of using clip in CSP for >5-10 mm sessile polyps was 40.1% (550/1 372), demonstrating notable variability among different endoscopists with median usage rate of 48.3% (29.8%, 67.9%).Conclusion:Varied resection methods are observed among endoscopists for sessile polyps measuring ≤19 mm. CFP is primarily utilized for polyps of 1-5 mm, while CSP is favored for polyps >5-10 mm, with an increasing annual usage rate. EMR is the main approach for the polyps >10-19 mm. Additionally, notable variations in the use of metal clips during CSP are observed among different physicians.

Globally, colorectal cancer (CRC) is a substantial public health burden, and it is increasingly affecting populations in Asian countries. The overall prevalence of CRC is reported to be low in Asia when compared with that in Western nations, yet it had the highest number of prevalent cases. This review described the prevalence of CRC in Asia according to the International Agency for Research on Cancer from World Health Organization (WHO) database and summarized its major risk factors. Non-modifiable factors include genetic factors, ethnicity, age, gender, family history and body height; smoking, alcohol drinking, weight, Westernized diet, physical inactivity, chronic diseases and microbiota were involved in environmental factors. These risk factors were separately discussed in this review according to published literature from Asian countries. CRC screening has been playing an important role in reducing its disease burden. Some recommendations on its screening practices have been formulated in guidelines for Asia Pacific countries.

Objective To investigate the rational program of colorectal cancer(CRC)screening between ages and genders by using single or repeated fecal immunochemical test(FIT)and colonoscopy. Methods Data of 6 193 patients who underwent opportunistic CRC screening at Peking Union Medical College Hospital were retrospectively analyzed.Patients were divided into four groups:(1)direct colonoscopy;(2)one FIT followed by colonoscopy;(3)two FITs followed by colonoscopy;(4)three FITs followed by colonoscopy.Cost-effectiveness of the four screening procedures was compared between different age groups and genders.Results Ninety-seven(1.6%)patients with CRC and 1 038(16.8%)with colorectal adenoma were detected. In patients younger than 40 years old,1-3 positive FIT strategies were superior to direct colonoscopy. In men aged 40 to 60,one or two positive FITs out of three was more cost-effective than direct colonoscopy,so was one positive FIT out of three in women aged 40 to 60. Direct colonoscopy was the most cost-effective strategy in men older than 60,while one positive FIT out of two was the best screening choice in women older than 60. Conclusion Age and gender are two influential factors for cost-effectiveness of CRC screening. Direct colonoscopy is the most cost-effective screening strategy for men older than 60,but one or more positive FIT followed by colonoscopy is preferred in other age and gender groups.

Objective To assess the fecal immunochemical test (FIT) followed by colonoscopy in opportunistic screenings for colorectal neoplasm.Methods Total 6 193 patients, who underwent opportunistic colorectal cancer (CRC) screening, were classified into four groups: 3 812 patients underwent direct colonoscopy (group 1), 1 244 patients received one FIT followed by colonoscopy (group 2), 341 patients received two FITs followed by colonoscopy (group 3), and 796 patients received three FITs followed by colonoscopy (group 4).Results Total 97 (1.6%) patients with CRC and 1 038 (16.8%) with colorectal adenoma were detected.The positive predictive value of 1, 2 and 3 positive tests out of three FITs for CRC were 4.53%, 5.62% and 8.94%, respectively, which was higher than that of direct colonoscopy (1.52%).One or more positive tests out of three FIT had the largest area under receiver operating characteristic curve (0.743).For colorectal adenoma, detection rate of direct colonoscopy (17 581.25/105) was higher than all FIT strategies (3 732.30/105-13 127.41/105).Conclusions Single or repeated FIT and colonoscopy have different screening utility.One or more positive tests out of three FIT followed by colonoscopy is preferred to screen CRC, and direct colonoscopy is better for detection of colorectal adenoma.

Objective: Based on the Cancer Screening Program in urban districts in Beijing from 2013 to 2014, target populations included pulmonary, mammary, esophageal, colorectal, hepatic and gastric cancers and precancerosis patients. The EQ-5D-3L and Functional Assessment of Cancer Therapy (FACT) questionnaires were used to measure the patients' quality of life and the reliability and validity of EQ-5D-3L and FACT were analyzed. Methods: The EQ-5D-3L and FACT questionnaires were used to measure 1 001 patients with cancer and precancerosis. The Cronbach's α coefficient was calculated to test the consistent reliability of EQ-5D-3L and FACT. The factor analysis was used to measure the construct validity of FACT and the FACT as standard to test the convergent validity of EQ-5D-3L. Results: Cronbach's α coefficients of EQ-5D-3L for pulmonary, breast, esophageal, colorectal, hepatic and gastric cancers were 0.846, 0.805, 0.877, 0.862, 0.793 and 0.844, respectively; the Cronbach's α coefficients of FACT were 0.935, 0.916, 0.950, 0.952, 0.915 and 0.953, respectively. The cumulative explained variances of FACT were 64.28%, 65.15%, 71.43%, 67.21%, 64.76% and 70.56%, respectively. Compared with FACT, the convergent validities of EQ-5D-3L were 0.592, 0.503, 0.715, 0.672, 0.561 and 0.444, respectively. The convergent validities of EQ-Visual Analogue Scale (VAS) were 0.553, 0.606, 0.576, 0.579, 0.361 and 0.364, respectively. Conclusion: EQ-5D-3L and FACT questionnaires for pulmonary, breast, esophageal, colorectal, hepatic and gastric cancers and the precancerosis patients are verified to have good reliabilities, and the FACT questionnaires of six types of cancers are being verified to have good construct validities. The EQ-5D-3L questionnaires for esophageal, colorectal, pulmonary, hepatic and breast cancers are being verified to have good convergent validities; but for the gastric cancer and precancerosis, there are limited validities.
