Feasibility and Colonoscopy Yield Using the Fecal Immunochemical Test (FIT)-Based Colorectal Cancer Screening in a Latin America Country. Clin Gastroenterol Hepatol 2024:S1542-3565(24)00161-7. [PMID: 38342277 DOI: 10.1016/j.cgh.2024.01.033] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/10/2023] [Revised: 01/15/2024] [Accepted: 01/16/2024] [Indexed: 02/13/2024]
Abstract
BACKGROUND & AIMS Organized colorectal cancer (CRC) screening is not widely practiced in Latin America and the results of regional studies may help overcome barriers for implementation of national screening programs. We aimed to describe the implementation and findings of a fecal immunochemical test (FIT)-based program in Brazil. METHODS In a prospective population-based study, asymptomatic individuals (50-75 years old) from Sao Paulo city were invited to undergo FIT for CRC screening. Participants with positive FIT (≥10 μg Hb/g feces) were referred for colonoscopy. Subjects were classified into groups according to the presence of CRC, precursor lesions, and other benign findings, possibly related to bleeding. RESULTS Of a total of 9881 subjects, 7.8% had positive FIT and colonoscopy compliance was 68.9% (n = 535). Boston scale was considered adequate in 99% and cecal intubation rate was 99.4%. CRC was diagnosed in 5.9% of the cases, adenoma in 63.2%, advanced adenoma in 31.4%, and advanced neoplasia in 33.0%. Age was positively associated with CRC (P = .03). Higher FIT concentrations were associated with increased detection of CRC (P < .008), advanced adenoma (P < .001), and advanced neoplasia (P < .001). CONCLUSIONS Implementation of a FIT-based CRC screening program was feasible in a low-resource setting, and there was a high yield for neoplasia in individuals with a positive FIT. This approach could be used as a model to plan and disseminate organized CRC screening more broadly in Brazil and Latin America.

APPLIED HEALTH ECONOMICS AND HEALTH POLICY 2023; 21:701-717.

Abstract
OBJECTIVE To assess the range of strategies analysed in European cost-effectiveness analyses (CEAs) of colorectal cancer (CRC) screening with respect to the screening intervals, age ranges and test cut-offs used to define positivity, to examine how this might influence what strategies are found to be optimal, and compare them with the current screening policies with a focus on the screening interval. METHODS We searched PubMed, Web of Science and Scopus for peer-reviewed, model-based CEAs of CRC screening. We included studies on average-risk European populations using the guaiac faecal occult blood test (gFOBT) or faecal immunochemical test (FIT). We adapted Drummond's ten-point checklist to appraise study quality. RESULTS We included 39 studies that met the inclusion criteria. Biennial screening was the most frequently used interval which was analysed in 37 studies. Annual screening was assessed in 13 studies, all of which found it optimally cost-effective. Despite this, 25 of 26 European stool-based programmes use biennial screening. Many CEAs did not vary the age range, but the 14 that did generally found broader ranges optimal. Only 11 studies considered alternative FIT cut-offs, 9 of which found lower cut-offs superior. Conflicts between current policy and CEA evidence are less clear regarding age ranges and cut-offs. CONCLUSIONS The existing CEA evidence indicates that the widely adopted biennial frequency of stool-based testing in Europe is suboptimal. It is likely that many more lives could be saved throughout Europe if programmes could be offered with more intensive annual screening.

Abstract
BACKGROUND The effects of recently implemented colorectal cancer screening programmes in Europe on colorectal cancer mortality will take several years to be fully known. We aimed to analyse the characteristics and parameters of screening programmes, proportions of colorectal cancers detected through screening, and stage distribution in screen-detected and non-screen-detected colorectal cancers to provide a timely assessment of the potential effects of screening programmes in several European countries. METHODS We conducted this population-based study in nine European countries for which data on mode of detection were available (Belgium, Denmark, England, France, Italy, Ireland, the Netherlands, Slovenia, and Spain). Data from 16 population-based cancer registries were included. Patients were included if they were diagnosed with colorectal cancer from the year that organised colorectal cancer screening programmes were implemented in each country until the latest year with available data at the time of analysis, and if their age at diagnosis fell within the age groups targeted by the programmes. Data collected included sex, age at diagnosis, date of diagnosis, topography, morphology, clinical and pathological TNM information based on the edition in place at time of diagnosis, and mode of detection (ie, screen detected or non-screen detected). If stage information was not available, patients were not included in stage-specific analyses. The primary outcome was proportion and stage distribution of screen-detected versus non-screen detected colorectal cancers. FINDINGS 228 667 colorectal cancer cases were included in the analyses. Proportions of screen-detected cancers varied widely across countries and regions. The highest proportions (40-60%) were found in Slovenia and the Basque Country in Spain, where FIT-based programmes were fully rolled out, and participation rates were higher than 50%. A similar proportion of screen-detected cancers was also found for the Netherlands in 2015, where participation was over 70%, even though the programme had not yet been fully rolled out to all age groups. In most other countries and regions, proportions of screen-detected cancers were below 30%. Compared with non-screen-detected cancers, screen-detected cancers were much more often found in the distal colon (range 34·5-51·1% screen detected vs 26·4-35·7% non-screen detected) and less often in the proximal colon (19·5-29·9% screen detected vs 24·9-32·8% non-screen detected) p≤0·02 for each country, more often at stage I (35·7-52·7% screen detected vs 13·2-24·9% non-screen detected), and less often at stage IV (5·8-12·5% screen detected vs 22·5-31·9% non-screen detected) p<0·0001 for each country. INTERPRETATION The proportion of colorectal cancer cases detected by screening varied widely between countries. However, in all countries, screen-detected cancers had a more favourable stage distribution than cancers detected otherwise. There is still much need and scope for improving early detection of cancer across all segments of the colorectum, and particularly in the proximal colon and rectum. FUNDING Deutsche Krebshilfe.

Abstract
INTRODUCTION Colorectal cancer (CRC) screening programs based on the fecal immunochemical test (FIT) and guaiac-based fecal occult blood (gFOBT) are associated with a substantial reduction in CRC incidence and mortality. We conducted a systematic review and comprehensive meta-analysis to evaluate colonoscopy-related adverse events in individuals with a positive FIT or gFOBT. METHODS A systematic and detailed search was run in January 2021, with the assistance of a medical librarian for studies reporting on colonoscopy-related adverse events as part of organized CRC screening programs. Meta-analysis was performed using the random-effects model, and the results were expressed for pooled proportions along with relevant 95% confidence intervals (CIs). RESULTS A total of 771,730 colonoscopies were performed in patients undergoing CRC screening using either gFOBT or FIT across 31 studies. The overall pooled incidence of severe adverse events in the entire patient cohort was 0.42% (CI 0.20-0.64); I2 = 38.76%. In patients with abnormal gFOBT, the incidence was 0.2% (CI 0.1-0.3); I2 = 24.6%, and in patients with a positive FIT, it was 0.4% (CI 0.2-0.7); I2 = 48.89%. The overall pooled incidence of perforation, bleeding, and death was 0.13% (CI 0.09-0.21); I2 = 22.84%, 0.3% (CI 0.2-0.4); I2 = 35.58%, and 0.01% (CI 0.00-0.01); I2 = 33.21%, respectively. DISCUSSION Our analysis shows that in colonoscopies performed after abnormal stool-based testing, the overall risk of severe adverse events, perforation, bleeding, and death is minimal.

Abstract
OBJECTIVE To evaluate the quality of colonoscopies performed after a positive faecal immunochemical test in the French colorectal cancer screening programme. METHODS Retrospective analysis of all colonoscopies performed between 2015 and 2019 after a positive quantitative faecal immunochemical test in the population-based colorectal cancer screening programme organised in Alsace, part of the French programme. The following indicators were evaluated: annual colonoscopy volume, caecal intubation rate, adenoma detection rate, proximal serrated lesion detection rate and proportion of patients referred directly to surgery for benign polyp management. Endoscopists who performed <30 faecal immunochemical test positive colonoscopies were non-assessable. RESULTS Overall, 13,455 faecal immunochemical test-positive colonoscopies performed by 116 community gastroenterologists were included, 13,067 of them by 80 assessable endoscopists. The overall caecal intubation, adenoma detection and proximal serrated lesion detection rates were 97.9%, 57.6% and 7.6%, respectively. They were <90%, <45% and <1% for 1.3%, 12.5% and 6.3% of the endoscopists, respectively. Overall, 1028 (7.9%) individuals were examined by 13 low-performing endoscopists and 328 (2.4%) individuals by 33 low-volume non-assessable endoscopists. Among 9133 individuals harbouring polyps, 155 (1.7%) had unwarranted surgery for a benign polyp. Overall, 1487 individuals (11.1%; 95% confidence interval 10.5-11.6) were not given the best possible chances, whereas 5545 individuals (41.2%; 95% confidence interval 40.4-42.0) were offered the best possible chances by 37 endoscopists. CONCLUSIONS At programme level, the key performance indicators evaluated largely exceeded the target standards. At individual level, at least one in nine individuals was not given the best possible chances during faecal immunochemical test-positive colonoscopies by a minority of poor-performing and/or low-volume endoscopists.

Abstract
BACKGROUND The risks associated with colonoscopy performed through the British Columbia Colon Screening Program (BCCSP) are not known. We aimed to determine the rate of colonoscopy-related serious adverse events within this program. METHODS For this prospective observational study, we used the BCCSP database to identify participants 50 to 74 years of age who had a positive result on fecal immunochemical testing (FIT) between Nov. 15, 2013, and Dec. 31, 2017, followed by colonoscopy. Unplanned medical events were recorded at the time of colonoscopy and 14 days later. We reviewed the unplanned events and defined them as serious adverse events if they resulted in death, hospital admission or intervention; we also classified them as probably, possibly or unlikely related to the colonoscopy. The primary outcome was the overall rate of serious adverse events; the secondary outcomes were 14-day post-colonoscopy rates of perforation, bleeding and death. RESULTS During the study period, a total of 96 192 colonoscopies were performed by 308 physicians at 50 sites. The median age of patients was 62 (10th-90th percentile 52-71) years, and 56% were male. Of these, 78 831 patients were contacted after the colonoscopy. Serious adverse events were deemed to have occurred in 350 colonoscopies (44 per 10 000, 95% confidence interval [CI] 39-50 per 10 000), with a number needed to harm of 225. Of the 332 (94.9%) serious adverse events that were probably or possibly related to colonoscopy, perforation occurred in 6 (95% CI 5-8) per 10 000 colonoscopies, bleeding in 26 (95% CI 22-30) per 10 000 colonoscopies and death in 3 (95% CI 1-10) per 100 000 colonoscopies. INTERPRETATION The rate of serious adverse events associated with colonoscopy in the BCCSP was in keeping with previous publications and met accepted benchmarks. The findings of this study inform stakeholders of the risks associated with colonoscopy in an FIT-based colon screening program.

Abstract
We aimed to assess the impact of the first three rounds of the National Colorectal Cancer Screening Program (NCCSP) on CRC incidence and mortality in Slovenia. In NCCSP, we use two fecal immune tests (FITs) and if test is positive patient is referred to colonoscopy. From 2009, we invite Slovenian residents aged 50-69 years, one screening round takes 2 years. The response rate was from 56.9 to 59.9%. FIT was positive in 6.0-6.2% (more in older patients and in men; P < 0.05). The adenoma detection rate was >51.3% (more in men; P < 0.01). In NCCSP, 70.3% of all cancers diagnosed were in stages I and II, while 20.7% of all CRC were found in polyps resected during colonoscopies. Patients with positive first FIT have odds ratio 2.19 [95% confidence interval (CI), 2.06-2.32] for advanced neoplasia and cancer compared to patients with two negative FITs. The incidence rate for CRC has dropped significantly after 6 years in population and in men (P < 0.01) but not in women. Five-year CRC survival was 31.3% higher if cancer was diagnosed in NCCSP (P < 0.05). After 6 years of NCCSP, the incidence rate for CRC has dropped significantly (P < 0.01). Hazard ratio for death from CRC was 3.84 higher (95% CI, 3.36-4.40; P < 0.001) in patients with cancer detected outside the program.

Abstract
Simple Summary The first Lithuanian analysis of colorectal cancer screening program is presented in our manuscript. We found that program is run with minimal expenses and still surpasses minimal requirements proposed by the European Union. Still the coverage is lower being 49.6% and must be improved. Abstract We aimed to report the results of the implementation of the National Colorectal Cancer (CRC) Screening Program covering all the country. The National Health Insurance Fund (NHIF) reimburses the institutions for performing each service; each procedure within the program has its own administrative code. Information about services provided within the program was retrieved from the database of NHIF starting from the 1 January 2014 to the 31 December 2018. Exact date and type of all provided services, test results, date and results of biopsy and histopathological examination were extracted together with the vital status at the end of follow-up, date of death and date of emigration when applicable for all men and women born between 1935 and 1968. Results were compared with the guidelines of the European Union for quality assurance in CRC screening and diagnosis. The screening uptake was 49.5% (754,061 patients) during study period. Participation rate varied from 16% to 18.1% per year and was higher among women than among men. Proportion of test-positive and test-negative results was similar during all the study period—8.7% and 91.3% annually. Between 9.2% and 13.5% of test-positive patients received a biopsy of which 52.3–61.8% were positive for colorectal adenoma and 4.6–7.3% for colorectal carcinoma. CRC detection rate among test-positive individuals varied between 0.93% and 1.28%. The colorectal cancer screening program in Lithuania coverage must be improved. A screening database is needed to systematically evaluate the impact and performance of the national CRC screening program and quality assurance within the program.

Abstract
OBJECTIVE To assess the feasibility and evaluate the performance of a relaunched colorectal cancer (CRC) screening programme with different cut-offs for men and women. DESIGN Population-based registry study. SETTING Nine municipalities in Finland which started CRC screening with faecal immunochemical test (FIT) in April 2019 with cut-off levels 70 µg Hg/g faeces for men and 25 µg Hg/g faeces for women. PARTICIPANTS Men (n=13 059) and women (n=14 669) aged 60-66 years invited to screening during the first programme year. OUTCOME MEASURES Participation rates, positivity rates, detection rates of CRC and advanced adenoma (AA), and positive predictive values (PPV) of FIT for CRC and AA. RESULTS Altogether 21 993 invitees returned stool samples. The participation rate of women (83.4%; 95% CI 82.8 to 84.0) was significantly higher than that of men (74.7%; 95% CI 73.9 to 75.4). The positivity rates were 2.4% (2.2 to 2.7) and 2.8% (2.5 to 3.1), respectively. In total, 37 CRCs and 116 AAs were detected. The detection rates of CRC and AA per 1000 participants were 1.8 (1.1 to 2.9) and 7.2 (5.6 to 9.1) for men and 1.6 (0.9 to 2.4) and 3.8 (2.8 to 5.0) for women. The PPVs per 100 positive tests were 6.6 (4.0 to 10.3) and 25.7 (20.6 to 31.4) for men and 6.4 (3.9 to 9.8) and 15.5 (11.6 to 20.2) for women. CONCLUSIONS The chosen FIT strategy narrowed the gap in the diagnostic performance between men and women especially in the detection of CRC. The participation rates were excellent. The levels of positivity and detection rates were moderate and need further action. The results indicate that gender-specific protocols can be introduced to organised CRC screening. It is yet to be seen whether they are more effective than a uniform screening protocol.

Abstract
OBJECTIVE The objective of this review was to assess the association between quality indicators used to evaluate individual colonoscopist performance and subsequent interval colorectal cancers (CRCs) in patients participating in bowel cancer screening programs. INTRODUCTION Colorectal cancer is a leading cause of cancer death. Bowel cancer screening has been shown to reduce CRC mortality and morbidity, and has therefore been introduced in many countries. Endoscopy societies have developed quality assurance guidelines and guidelines on quality indicators for screening colonoscopies. These quality indicators need to be validated against a relevant outcome to assess their value. INCLUSION CRITERIA We included studies on screening colonoscopies conducted on participants in a bowel cancer screening program, regardless of comorbidity. Studies on procedures performed on patients with known CRC, hereditary nonpolyposis colorectal cancer or familial adenomatous polyposis were excluded. We also included studies evaluating the quality indicators of withdrawal time (WT), cecal intubation rate (CIR) and adenoma detection rate (ADR). The search did not reveal any studies evaluating the quality indicators polyp retrieval rate and incomplete adenoma resection/incomplete polyp resection. Only studies with interval CRC as an outcome were included (i.e. CRC diagnosed after a negative screening colonoscopy, but before the next recommended examination date). METHODS Published studies were searched in: MEDLINE, Embase, Web of Science and CINAHL. Unpublished studies were searched in: OpenGrey and Grey Literature Report. The sources were searched from 1980 to2018. Data were extracted using the JBI critical appraisal checklist for analytical cross sectional studies. A meta-analysis was conducted based on three of the colonoscopist dependent quality indicators: WT, CIR and ADR. RESULTS Seven prospective and retrospective cohort studies were included out of 2373 papers identified after duplicates were removed. The included studies were on bowel cancer screening programs with colonoscopy as the primary screening tool, resulting in the inclusion of a total of 616,390 screening colonoscopies performed by 1431 colonoscopists and 2319 subsequent interval CRCs. Six studies were assessed as high-quality studies, and one study was of low quality. The meta-analysis on WT revealed a 61% lower risk of interval CRC among the patients if the mean WT per colonoscopist was >6 minutes as compared to a mean WT of <6 minutes (RR: 0.39 [95% CI: 0.23 - 0.66]). The meta-analysis on CIR revealed a 31% lower risk of interval CRC among the patients if the CIR per colonoscopist was ≥90% as compared to a CIR of <85% (RR: 0.69 [95% CI: 0.56 - 0.83]). One of two meta-analyses on the individual colonoscopist ADR suggested that this should be 15-19%, as compared to an ADR <10% (RR: 0.77 [95% CI: 0.62 - 0.96]), in order to significantly reduce the risk of interval CRC. The other meta-analysis on ADR revealed a significant association between an individual colonoscopist ADR of ≥25% and a lower risk of interval CRC as compared to an ADR of <25% (RR: 0.51 [95% CI: 0.33 - 0.80]). The meta-analyses on WT and CIR showed no heterogeneity concerning the significant results (I = 0.0%). A high variability across studies due to heterogeneity concerning an ADR of ≥20% resulted in an I = 59.9%, and an I = 63.2% for an ADR of ≥25%. CONCLUSIONS To minimize the risk of interval CRC, it may be recommended that WT and CIRs are monitored in bowel cancer screening programs, with an optimal individual colonoscopist mean withdrawal time of >6 minutes and a cecal intubation rate of ≥90%. In bowel cancer screening programs using colonoscopy as their primary screening tool, it may be recommended that the individual colonoscopist ADR be 15-19% or better ≥25% to minimize the risk of interval CRC.

Utilisation of Colorectal Cancer Screening Tests in European Countries by Type of Screening Offer: Results from the European Health Interview Survey. Cancers (Basel) 2020; 12:cancers12061409.

Abstract
In the past two decades, an extensive rollout of colorectal cancer (CRC) screening programmes has been initiated in European countries with a large heterogeneity of screening offers. Using data from a population-based cross-sectional survey conducted between 2013 and 2016 in all European Union countries, we analysed the utilisation of faecal tests and colonoscopy among people aged 50–74 years and the factors associated with uptake by type of screening offer. We observed the highest utilisation of either test for countries with fully rolled out organised programmes with faecal tests (ranging from 29.7% in Croatia to 66.7% in the UK) and countries offering both faecal tests and colonoscopy (from 22.7% in Greece to 70.9% in Germany). Utilisation was very low for countries with no programme (from 6.3% in Romania to 30.5% in Norway). Younger age (50–54 years), longer time since last consultation with a doctor and a lifestyle score associated with increased CRC risk were significantly associated with lower test use, a pattern observed across all types of screening offers. Our results suggest that more countries should implement organised programmes with faecal immunochemical tests, in combination with alternative endoscopy offers where resources allow. Furthermore, there is a large potential for increasing screening use in Europe by better reaching the younger eligible individuals, those who have not been to the doctor recently and those at increased risk for CRC.

Abstract
Objective: From the prevalent round of the Danish FIT-based colorectal cancer (CRC) screening program, we aimed (i) to evaluate the quality of recorded data and (ii) to characterize the colonoscopies by measuring variation in performance indicators between colonoscopists and assessing the ratio between adenoma detection rate (ADR) and polyp detection rate (PDR). Materials and methods: This study included screening colonoscopies performed in Central Denmark Region within 60 days of a positive FIT-result from 1 July 2015 through 30 June 2017. The participants were the colonoscopists, performing these procedures. The quality indicators cecal intubation rate (CIR), PDR, polyp retrieval rate (PRR), ADR and withdrawal time (WT) were evaluated. ADR/PDR ratios were calculated. Results: The concordance between the recorded data and the colonoscopy reports showed Kappa values in the range of 0.47-0.97. The overall CIR was 90.6% (range 73.7%-100%), PDR: 51.9% (range 18.4%-70.2%), PRR: 94.6% (range 69.6%-100%), ADR (conventional adenomas): 50.6% (range 18.4%-70.2%), ADRx (conventional adenomas, traditional serrated adenomas and sessile serrated lesions with dysplasia): 50.9% (range 18.4%-70.2%) and the mean WT was 11.3 min (range 4.5-24.9 min). The ADR/PDR ratio was 92.8% (95% CI: 92.0%-93.6%) and the ADRx/PDR ratio was 93.2% (95% CI: 92.4%-93.9%). Conclusion: Data quality was generally high. We found considerable variation in performance indicators between colonoscopists reflecting the potential for improvement. Further, our findings revealed that the PDR might be a good proxy for ADR in the context of the prevalent round of FIT-based CRC screening programs.

Abstract
Colorectal cancer accounts for 11% of all cancer-related deaths in Ireland. With the aim of diagnosing these cancers at an earlier stage, and detecting premalignant lesions, the National Screening Service (NSS) offered a fecal immunochemical test (FIT) to all individuals aged 60 to 69. All individuals in the age range were contacted by post and invited to participate in the programme. Those with a positive FIT result were offered a colonoscopy in an internationally accredited unit. From an eligible population of 488,628, 196,238 individuals participated giving an uptake of 40.2%. Commencing at a FIT threshold of 20 μg Hg/g feces, the positivity rate was 8.6%, which overwhelmed colonoscopy capacity and, thus, the threshold was increased to 45 μg, resulting in an overall 5% positivity rate. A total of 520 individuals had cancer detected (68.3% stage I or II), of which 104 were removed endoscopically (pT1s). Adenomas were present in 54.2% of all colonoscopies, 17.4% deemed high risk. Despite a lower uptake, males were twice as likely to have colorectal cancers as females and had a 59% increased rate of high-risk adenomas diagnosed. Challenges facing the programme include increasing participation, especially among males, and increasing colonoscopy capacity. The ability to alter the sensitivity of FIT to match colonoscopy capacity is a valuable option for such a programme as it ensures that the maximum public health benefit can be achieved within available resources.

Abstract
Background The Danish national screening program for colorectal cancer (CRC) consists of an immunochemical fecal occult blood test (iFOBT) followed by colonoscopy. The Danish Colorectal Cancer Screening Database (DCCSD) records data on the incidence of hospital-registered complications after colonoscopy. However, the validity of these data is unknown, and the incidence of complications is potentially underreported. Objective To evaluate the validity of the colonoscopy complications registered in the DCCSD by using medical records as the reference. Further, to evaluate the incidence of complications leading to hospital contact. Methods Among 14,671 individuals with a positive iFOBT result and a colonoscopy procedure performed from March 3, 2014 to December 31, 2014, we selected 295 individuals for medical record review. We calculated sensitivity as the proportion of true complications registered in the DCCSD out of all complications found in the medical records, and the positive predictive value (PPV) as the number of true complications in the DCCSD out of all DCCSD-registered complications. On the basis of the medical record data, we calculated the incidence proportion of hospital-registered complications overall and by subtype. Results In total, we reviewed 286 records and found 102 individuals with at least one complication. The sensitivity of the DCCSD for any complication was 29.4% (95% CI: 20.8–39.3) and the PPV was 88.2% (95% CI: 72.6–96.7). On the basis of the medical record data, the incidence proportion of any complication after colonoscopy was 0.70% (95% CI: 0.57–0.84) and that of perforation or lesion was 0.10% (95% CI: 0.06–0.17); bleeding, 0.41% (95% CI: 0.31–0.53); post-polypectomy syndrome, 0.16% (95% CI: 0.10–0.24); and other medical complications, 0.04 (95% CI: 0.02–0.09). Conclusion The DCCSD has low sensitivity for complications, and improvements in data registration are warranted. The incidence proportion of any hospital-treated post-colonoscopy complication was 0.70% in 2014, which was the first year of the Danish national CRC screening program. This is within the range of complications reported by other studies.

Abstract
Background and study aims To compare the quality of colonoscopy in a population-based coordinated program of colorectal cancer screening according to type of hospital (academic or non-academic). Patients and methods Consecutive patients undergoing colonoscopy after positive FIT (≥ 20 ug Hb/g feces) between January 2009 and September 2016 were prospectively included at five academic and seven non-academic public hospitals. Screening colonoscopy quality indicators considered were adenoma detection rate, cecal intubation rate, complications and bowel preparation quality. Results A total of 48,759 patients underwent colonoscopy, 34,616 (80 %) in academic hospitals and 14,143 in non-academic hospitals. Among these cases, 19,942 (37.1 %) advanced adenomas and 2,607 (5.3 %) colorectal cancers (CRCs) were detected, representing a total of 22,549 (46.2 %) cases of advanced neoplasia. The adenoma detection rate was 64 %, 63.1 % in academic hospitals and 66.4 % in non-academic hospitals ( P < 0.001). Rates of advanced adenoma detection, cecal intubation and adequate colonic preparation were 45.8 %, 96.2 % and 88.3 %, respectively, and in all cases were lower (implying worse quality care) in academic hospitals (45.3 % vs 48.7 %; odds ratio [OR] 0.87, 95 % confidence interval [CI] 0.84 - 0.91; 95.9 % vs 97 %; OR 0.48, 95 % CI 0.38 - 0.69; and 86.4 % vs 93 %; OR 0.48, 95 % CI 0.45 - 0.5; respectively; P < 0.001 in all cases). In 13 patients, all in the academic hospital group, CRC was diagnosed after colonoscopy (0.26 cases × 1000 colonoscopies). Rates of CRC treated by endoscopy were similar in both types of hospital (30 %). The rate of severe complication was 1.2 % (602 patients), with no significant differences by hospital type: bleeding occurred in 1/147 colonoscopies and perforation in 1/329. One patient died within 30 days after screening colonoscopy. Conclusions The quality of colonoscopy was better in non-academic hospitals. The rate of detection of advanced neoplasia was higher in non-academic hospitals and correlated with the rate of post-colonoscopy CRC.

Abstract
Background We assessed the incidence and characteristics of interval cancers after faecal immunochemical occult blood test and calculated the test sensitivity in Slovenian colorectal cancer screening programme. Patients and methods The analysis included the population aged between 50 to 69 years, which was invited for screening between April 2011 and December 2012. The persons were followed-up until the next foreseen invitation, in average for 2 years. The data on interval cancers and cancers in non-responders were obtained from cancer registry. Gender, age, years of schooling, the cancer site and stage were compared among three observed groups. We used the proportional incidence method to calculate the screening test sensitivity. Results Among 502,488 persons invited for screening, 493 cancers were detected after positive screening test, 79 interval cancers after negative faecal immunochemical test and 395 in non-responders. The proportion of interval cancers was 13.8%. Among the three observed groups cancers were more frequent in men (p = 0.009) and in persons aged 60+ years (p < 0.001). Comparing screen detected and cancers in non-responders with interval cancers more interval cancers were detected in persons with 10 years of schooling or more (p = 0.029 and p = 0.001), in stage III (p = 0.027) and IV (p < 0.001), and in right hemicolon (p < 0.001). Interval cancers were more frequently in stage I than non-responders cancers (p = 0.004). Test sensitivity of faecal immunochemical test was 88.45%. Conclusions Interval cancers in Slovenian screening programme were detected in expected proportions as in similar programmes. Test sensitivity was among the highest when compared to similar programmes and was accomplished using test kit for two stool samples.

Abstract
Colorectal cancer (CRC) is a significant cause of morbidity and mortality worldwide. However, colon cancer incidence and mortality is declining over the past decade owing to adoption of effective screening programs. Nevertheless, in some parts of the world, CRC incidence and mortality remain on the rise, likely due to factors including “westernized” diet, lifestyle, and lack of health-care infrastructure and resources. Participation and adherence to different national screening programs remain obstacles limiting the achievement of screening goals. Different modalities are available ranging from stool based tests to radiology and endoscopy with varying sensitivity and specificity. However, the availability of these tests is limited to areas with high economic resources. Recently, FDA approved a blood-based test (Epi procolon®) for CRC screening. This blood based test may serve to increase the participation and adherence rates. Hence, leading to increase in colon cancer detection and prevention. This article will discuss various CRC screening tests with a particular focus on the data regarding the new approved blood test. Finally, we will propose an algorithm for a simple cost-effective CRC screening program.
