[PMID: 39088934 DOI: 10.1016/j.clinimag.2024.110241] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/07/2024] [Revised: 06/27/2024] [Accepted: 07/23/2024] [Indexed: 08/03/2024]
Abstract
PURPOSE Computed tomographic colonography (CTC) is a non-invasive screening test for colorectal cancer (CRC) with high sensitivity and low risk of complications. We used a nationally representative sample of screening-eligible adults to examine trends in and factors associated with CTC use. METHODS We examined CTC use among 58,058 adults in the National Health Interview Survey in 2010, 2015, 2018, 2019, and 2021. For each survey year, we estimated CTC use by sociodemographic and health factors. We used multivariable logistic regression to identify factors associated with CTC use. RESULTS A total of 1.7 % adults reported receiving CTC across all survey years. CTC use was similar in 2010 (1.3 %), 2015 (0.8 %), 2018 (1.4 %), and 2019 (1.4 %) but increased in 2021 (3.5 %, p < 0.05). In multivariable analysis, survey year 2021 [vs. 2010, odds ratio (OR) 2.51, 95 % confidence interval (CI) 1.83-3.43], Hispanic (OR 1.73, 95 % CI 1.34-2.23), non-Hispanic Black (OR 2.07, 95 % CI 1.67-2.57), and household income <200 % federal poverty level (vs. >400 %, OR 1.25, 95 % CI 1.01-1.57) was associated with CTC use. Further, adults with a history of diabetes (OR 1.20, 95 % CI 1.01-1.45), chronic obstructive pulmonary disease (OR 1.58, 95 % CI 1.25-1.99), cancer (OR 1.29, 95 % CI 1.05-1.58), or past-year hospital admissions (OR 1.44, 95 % CI 1.18-1.78) were more likely to receive CTC. CONCLUSION CTC use remained low from 2010 to 2019 but increased in 2021. CTC use was more frequent among adults with chronic health conditions, minorities, and adults with lower income, and may help reduce disparities in CRC screening.

Socioeconomic differences in discrepancies between expected and experienced discomfort from colonoscopy and colon capsule endoscopy. Heliyon 2024; 10:e34274. [PMID: 39100485 PMCID: PMC11295845 DOI: 10.1016/j.heliyon.2024.e34274] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/25/2023] [Revised: 03/07/2024] [Accepted: 07/07/2024] [Indexed: 08/06/2024] Open
Abstract
Background Social inequalities in colorectal cancer screening participation are evident. Barriers to screening participation include discomfort from diagnostic modalities. We aimed to describe the discomfort experienced from colonoscopy and colon capsule endoscopy (CCE) and investigate the discrepancy between expected and experienced discomfort stratified by socioeconomic status. Methods A randomised controlled trial was conducted offering half of the colorectal cancer screening invitees the choice between CCE and colonoscopy after a positive faecal immunochemical test. This paper includes those who elected to undergo CCE. A positive CCE elicited referral for a therapeutic colonoscopy. Participants reported their discomfort from CCE and from any following colonoscopies in electronically distributed questionnaires. Discomfort was measured using visual analogue scales and compared between socioeconomic subgroups determined by educational level and income. Results The experienced discomfort from CCE and colonoscopy differed significantly between educational levels but not income levels. The bowel preparation contributed the most to the experienced discomfort in both CCE and colonoscopy. The discrepancy between expected and experienced discomfort from colonoscopy increased with increasing educational and income levels. A similar trend was seen in CCE between educational levels but not income levels. Conclusions None of the results indicated a higher discomfort in lower socioeconomic subgroups. Regardless of the investigation modality, the bowel preparation was the main contributor to experienced discomfort. The discrepancy between expected and experienced discomfort did not seem to be larger in lower socioeconomic subgroups, indicating that this is not a major barrier causing inequalities in screening uptake. This is the first study investigating individual discomfort discrepancy in both CCE and colonoscopy, while being able to stratify by socioeconomic status.

A digital intake tool to avert outpatient visits in a FIT-based colorectal cancer screening population: study protocol of a multicentre, prospective non-randomized trial - the DIT-trial. BMC Gastroenterol 2024; 24:38. [PMID: 38238726 PMCID: PMC10797858 DOI: 10.1186/s12876-023-03039-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/18/2023] [Accepted: 11/07/2023] [Indexed: 01/22/2024] Open
Abstract
BACKGROUND Currently all participants of the Dutch colorectal cancer (CRC) screening program with a positive faecal immunochemical test (FIT) are seen at the outpatient clinic to assess their health status, receive information on colonoscopy and CRC risk, and provide informed consent. However, for many patients this information could probably also safely be exchanged in an online setting, in order to reduce the burden for patients, healthcare system, and environment. In this study we will evaluate if a face-to-face pre-colonoscopy consultation can be replaced by a Digital Intake Tool (DIT) in a CRC screening population. METHODS This is a prospective multicentre single-arm, non-randomized study with a non-inferiority design. The DIT will triage a total of 1000 participants and inform them about CRC risk, colonoscopy, sedation, and provide bowel preparation instructions. Participants identified as high-risk (i.e., red-triaged) will be contacted by phone or scheduled for an appointment at the outpatient clinic. The primary outcome measure will be adequate bowel preparation rate, defined as the proportion of participants with a Boston Bowel Preparation (BBPS) score ≥ 6. To compare our primary outcome, we will use colonoscopy data from 1000 FIT positive participants who visited the outpatient clinic for pre-colonoscopy consultation. Secondary outcomes will include participation rate, colonoscopy adherence rate, patient experience in terms of satisfaction and anxiety, knowledge transfer, number of outpatient visits that can be averted by the DIT, and cost-effectiveness of the tool. Ethical approval was obtained from the Medical Ethical Committee of the Erasmus Medical Center (MEC-2021-0098). DISCUSSION This study aims to assess if a face-to-face pre-colonoscopy consultation can be replaced by an eHealth assessment and education tool in a FIT-based CRC screening program. In case favourable results are established, the intervention evaluated in this study could significantly impact CRC screening programs, benefiting both patients and healthcare systems on a (inter)national scale. Additionally, it would enable more personalized care as the DIT can be easily customized and made feasible in other languages, thereby enhancing healthcare accessibility. TRIAL REGISTRATION Dutch Trial Register: NL9315 , date of registration: March 8th, 2021.

JAMA Netw Open 2023; 6:e2343392. [PMID: 37971743 PMCID: PMC10654798 DOI: 10.1001/jamanetworkopen.2023.43392] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/19/2023] [Accepted: 09/15/2023] [Indexed: 11/19/2023] Open
Abstract
Importance Despite recommendations for universal screening, adherence to colorectal cancer screening in the US is approximately 60%. Liquid biopsy tests are in development for cancer early detection, but it is unclear whether they are cost-effective for colorectal cancer screening. Objective To estimate the cost-effectiveness of liquid biopsy for colorectal cancer screening in the US. Design, Setting, and Participants In this economic evaluation, a Markov model was developed to compare no screening and 5 colorectal cancer screening strategies: colonoscopy, liquid biopsy, liquid biopsy following nonadherence to colonoscopy, stool DNA, and fecal immunochemical test. Adherence to first-line screening with colonoscopy, stool DNA, or fecal immunochemical test was assumed to be 60.6%, and adherence for liquid biopsy was assumed to be 100%. For colonoscopy, stool DNA, and fecal immunochemical test, patients who did not adhere to testing were not offered other screening. In colonoscopy-liquid biopsy hybrid, liquid biopsy was second-line screening for those who deferred colonoscopy. Scenario analyses were performed to include the possibility of polyp detection for liquid biopsy. Exposures No screening, colonoscopy, fecal immunochemical test, stool DNA, liquid biopsy, and colonoscopy-liquid biopsy hybrid screening. Main Outcomes and Measures Model outcomes included life expectancy, total cost, and incremental cost-effectiveness ratios. A strategy was considered cost-effective if it had an incremental cost-effectiveness ratio less than the US willingness-to-pay threshold of $100 000 per life-year gained. Results This study used a simulated cohort of patients aged 45 years with average risk of colorectal cancer. In the base case, colonoscopy was the preferred, or cost-effective, strategy with an incremental cost-effectiveness ratio of $28 071 per life-year gained. Colonoscopy-liquid biopsy hybrid had the greatest gain in life-years gained but had an incremental cost-effectiveness ratio of $377 538. Colonoscopy-liquid biopsy hybrid had a greater gain in life-years if liquid biopsy could detect polyps but remained too costly. Conclusions and Relevance In this economic evaluation of liquid biopsy for colorectal cancer screening, colonoscopy was a cost-effective strategy for colorectal cancer screening in the general population, and the inclusion of liquid biopsy as a first- or second-line screening strategy was not cost-effective at its current cost and screening performance. Liquid biopsy tests for colorectal cancer screening may become cost-effective if their cost is substantially lowered.

Abstract
African Americans continue to have a low rate of colonoscopy screening despite the U.S. Preventive Services Taskforce's (USPSTF) recommendations and its proven benefits. Colonoscopy has proven to be an effective screening and therapeutic procedure. Understanding the root cause of the problem is a crucial step toward achieving the desired colonoscopy rate among this population. This paper evaluates factors that contribute to the underutilization of colonoscopy. The paper also analyzes strategies that could be maximized to increase colonoscopy rates, minimize colorectal cancer inequalities, and promote optimal colorectal health among African Americans.

Abstract
AIMS To systematically examine and review relevant qualitative studies exploring the current lifestyle among individuals at high risk of colorectal cancer (CRC), and their awareness of the role of a healthy lifestyle in CRC prevention. BACKGROUND The increasing incidence and mortality of CRC have presented a serious threat against the health and life of people. As the major population affected by CRC, the lifestyle of individuals at a high risk of CRC is attracting increasing attention. DESIGN A qualitative evidence synthesis using the Thomas and Harden method and the PRISMA 2020 checklist provided by the EQUATOR network were used. DATA SOURCES Literature was retrieved from PubMed, Web of Science, the Cochrane Library, Embase, CINAHL and PsycINFO from the inception to December 2021. REVIEW METHODS Two reviewers independently screened the titles and abstracts and identified the eligible studies. Critical appraisals of each included study were performed. Thematic analysis was used to guide the data synthesis. RESULTS The data from nine articles were analysed. Three interpretive themes were extracted that formed an overarching synthesis of the experience with healthy lifestyles among high-risk individuals of CRC. The findings suggested that these individuals with limited awareness of CRC and personal risks lacked sufficient knowledge about the relationship between lifestyle and CRC, and their attitudes and practices towards the role of a healthy lifestyle in CRC prevention were also diversified. CONCLUSION Professionals can potentially provide personalised guidance for healthy lifestyles based on knowledge of prevention, the actual background and social support of individuals at high risk of CRC. IMPACT Considering that knowledge gaps and health beliefs among these individuals are the premise blocking their adoption of a healthy lifestyle, the findings of this review may make contributions to the design and content of public health policy and prevention programs. No patient or public contribution.

Fatalism and metaphor in Confucianism: A qualitative study of barriers to genetic testing among first-degree relatives of hereditary cancer patients from China. Psychooncology 2023; 32:275-282. [PMID: 36380559 PMCID: PMC10099923 DOI: 10.1002/pon.6068] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/21/2022] [Revised: 09/01/2022] [Accepted: 09/26/2022] [Indexed: 11/17/2022]
Abstract
OBJECTIVE Despite the benefits, the rate of genetic testing among first-degree relatives (FDRs; parents, children, and siblings) remains low, and the barriers to undergoing testing among FDRs in China are not clear. We explored the reasons why FDRs refused genetic testing. METHODS Semi-structured face-to-face interviews were conducted with 22 patients and 27 FDRs. Participants were recruited at an urban tertiary hospital in Guangzhou, South China. We used qualitative content analysis to analyse the transcripts of audio recordings and identify major themes and subthemes. RESULTS Three major themes emerged related to FDRs' low rate of participation in genetic testing. First, there is cognitive distance from genetic testing/cancer and a lack of knowledge of preventive medicine that deepens the 'fatalistic' attitude towards cancer among FDRs, which leads to an enormous gap between their knowledge and understanding of genetic testing. Second, medical consultation is not valued in Confucianism, and the view of cancer as 'bad news' and the risk of cancer as a curse makes cancer a metaphor, which leads to exhausting arguments when persuading FDRs to undergo genetic testing. Third, physical distance from the hospital, loss of privacy, possible discrimination in many social activities and genetic testing as a source of stress and anxiety lead FDRs to fear the disruption of their daily lives. CONCLUSIONS There are many barriers to genetic testing among the FDRs of hereditary cancer patients originating from the national social and cultural context. Healthcare professionals should develop interventions rooted in culture and promote cancer risk communication between hereditary cancer patients and FDRs.

Abstract
PURPOSE We aimed to assess participant-reported factors associated with non-follow-up with colonoscopy in colorectal cancer (CRC) screening. METHODS In May 2019, we distributed a nationwide cross-sectional questionnaire (n = 4,009) to participants in the Dutch CRC screening program who received a positive fecal immunochemical test (FIT). Among respondents who reported no colonoscopy, we assessed the presence of a contraindication, and those without were compared with those who reported colonoscopy by logistic regression analysis. RESULTS Of 2,225 respondents (56% response rate), 730 (33%) reported no colonoscopy. A contraindication was reported by 55% (n = 404). Decisional difficulties (odds ratio [OR] = 0.29; 95% CI, 0.18-0.47), lacking the opportunity to discuss the FIT outcome (OR = 0.45; 95% CI, 0.28-0.72), and a low estimated risk of CRC (OR = 0.45; 95% CI, 0.26-0.76) were negatively associated with follow-up. Knowledge items negatively associated with follow-up included having an alternative explanation for the positive FIT (OR = 0.3; 95% CI, 0.21-0.43), having trust in the ability to self-detect CRC (OR = 0.42; 95% CI, 0.27-0.65), and thinking that polyp removal is ineffective (OR = 0.59; 95% CI, 0.43-0.82). The belief that the family physician would support colonoscopy showed the strongest positive association with follow-up (OR = 2.84; 95% CI, 2.01-4.02) CONCLUSIONS: Because decisional difficulties and certain convictions regarding CRC and screening are associated with non-follow-up, personalized screening counseling might be an intervention worth exploring as a means of improving follow-up in the Dutch CRC screening program. Involving family physicians might also prove beneficial.

Psychosocial determinants of colorectal Cancer screening uptake among African-American men: understanding the role of masculine role norms, medical mistrust, and normative support. ETHNICITY & HEALTH 2022; 27:1103-1122. [PMID: 33249920 PMCID: PMC8163893 DOI: 10.1080/13557858.2020.1849569] [Citation(s) in RCA: 17] [Impact Index Per Article: 8.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/21/2020] [Accepted: 11/02/2020] [Indexed: 05/04/2023]
Abstract
OBJECTIVES Despite having the highest colorectal cancer (CRC) incidence and mortality across all major racial/ethnic groups, African-American men consistently have poor CRC screening rates. Gendered and racialized beliefs and norms have been associated with African-American men's lower medical assistance-seeking rates, but how these notions influence African-American men's CRC screening practices merits further investigation. The purpose of this study was to examine the influence of psychosocial determinants of men's health on CRC screening uptake among African-American men in three states. DESIGN Participants were recruited via CuttingCRC.com and through culturally-tailored flyers, newspaper ads, and snowball sampling, among other methods. From April 2019-August 2019, 11 focus groups were conducted with English-speaking Black/African-American men who (a) were between ages 45-75, (b) were born in the United States, (c) had a working telephone, and (d) lived in Minnesota, Ohio, or Utah. Multiple-cycle coding, Hatch's 9-step approach, and constant comparative data analysis was employed for de-identified transcript data. RESULTS Eighty-four African-American men met inclusion criteria and participated. Their mean age was 59.34 ± 7.43. In regards to CRC screening status, Ohio had the most previously screened participants (85%), followed by Minnesota (84%) and Utah (76%). Two major CRC screening barriers (masculine role norms and medical mistrust) - both encompassed 3-5 subthemes, and one major facilitator (normative support from family members or social networks) emerged. CONCLUSIONS Despite CRC screening's life-saving potential, African-American men have had the lowest 5-year relative survival for more than 40 years. When developing interventions and health promotion programs aiming to eliminate the racial disparity in CRC outcomes, addressing both masculine role norms and medical mistrust barriers to CRC screening completion among African-American men is warranted.

Abstract
OBJECTIVES To investigate the psychosocial consequences of receiving a false-positive (no abnormalities) result or being diagnosed with polyps compared with receiving a negative result in a colorectal cancer (CRC) screening programme. DESIGN AND SETTING This was a longitudinal study nested in the roll-out of the Danish CRC screening programme that targets all individuals aged 50-74 years. PARTICIPANTS In the inclusion period (April-September 2017), all positive screenees (n=1854) were consecutively enrolled and matched 2:1:1 on sex, age (±2 years), municipality and screening date with negative screenees (n=933) and individuals not yet invited to screening (n=933).Questionnaires were sent by mail to all eligible participants in Region Zealand, Denmark, after the screening result, 2 months and 12 months after the final result.Positive screenees who did not receive the follow-up procedure were excluded. MAIN OUTCOME MEASURES The primary outcomes were psychosocial consequences. Outcomes were measured with the CRC screening-specific questionnaire Consequences of screening in CRC with 11 outcomes after the screening result and with 21 outcomes at the two later assessments. RESULTS After receiving the screening result, individuals with no abnormalities, low-risk and medium-risk and high-risk polyps scored significantly worse on 8 of 11 outcomes compared with the negative screenee group. At the 12-month follow-up, the differences were still significant in 8 of 21 outcomes (no abnormalities), 4 of 21 outcomes (low-risk polyps) and 10 of 21 outcomes (medium-risk and high-risk polyps). The negative screenee group and the group not yet invited to screening differed psychosocially on 5 of 11 outcomes after the screening result, but on none of the 21 outcomes at the 2 months and 12 months follow-up. CONCLUSIONS The study showed that there are both short-term and long-term psychosocial consequences associated with receiving a no abnormalities result or being diagnosed with polyps. The consequences were worst for individuals diagnosed with medium-risk and high-risk polyps.

Abstract
OBJECTIVES Colonoscopy is integral in the early detection of colorectal cancer (CRC), be it for screening, diagnostic or therapeutic intentions. Despite the presence of multiple screening modalities, colonoscopy remains integral in providing a definitive CRC diagnosis. However, uptake rates remain low worldwide with minimal understanding towards stakeholders' perspectives. This systematic review is the first to outline the barriers and facilitators faced by providers and patients in receiving colonoscopy specifically. METHODS Using PRISMA guidelines, our systematic review consolidates findings from Medline, Embase, CINAHL, PsycINFO and Web of Science Core collection. All perceptions of healthcare providers and screening participants aged 45 and above towards colonoscopy were included. RESULTS Forty-five articles were included in our review. Five major analytical themes were identified - procedural perceptions, personal experiences, thoughts and concerns, societal influences, doctor-patient relationship and healthcare system. The discrepancies in knowledge between patients and providers have evidently reduced in the present decade, potentially attributable to the rising influence of social media. The sharing of providers' personal experiences, involvement of patients' family in colonoscopy recommendations and propagation of patients' positive recounts were also more apparent in the past compared to the present decade, highlighting the need to reevaluate the balance between medical confidentiality and personal touch. Additionally, Asian patients were reportedly more apathetic towards CRC diagnosis due to their strong belief in destiny, a crucial association consistent with present studies. CONCLUSION This study highlights pertinent gaps in our healthcare system, providing crucial groundwork for interventions to be enacted in engendering higher colonoscopy uptake rates.

Abstract
BACKGROUND Colorectal cancer screening can reduce the incidence and mortality through early detection. First-degree relatives (FDRs) of patients with colorectal cancer are at high risk for colorectal cancer and therefore require colonoscopy. However, despite the high risk, screening adherence among FDRs remains low and the barriers to undergoing screening among FDRs in China are not clear. We explored the reasons why FDRs refused screening. METHODS In this qualitative study, 28 semistructured, in-depth interviews were conducted face-to-face. Participants were recruited at two hospitals (an urban tertiary hospital and a community health center) in Guangzhou, South China. We used qualitative content analysis to analyze transcripts based on audio recordings and identify major themes and subthemes. RESULTS Three major themes emerged related to FDRs' low screening participation. First, the emotional distance between FDRs and medicine was pulled away by uncomfortable feelings approaching hospitals and misunderstanding of cancer. Second, they confirmed their health state and minimized cancer risk if they had no signs in routine health examination, no symptoms and maintained a healthy, happy life. Third, they considered screening far from their daily life from the perspective of spatial distance and priority. Therefore, screening was not necessary in their view. CONCLUSIONS Healthcare professionals should narrow psychological distance between people and screening when promoting screening technology.

Abstract
SETTING Participants with a positive faecal immunochemical test (FIT) in screening programs for colorectal cancer (CRC) have a high risk for colorectal cancer and advanced adenomas. They are therefore recommended follow-up by colonoscopy. However, more than ten percent of positively screened persons do not adhere to this advice. OBJECTIVE To investigate FIT-positive individuals' motives for non-adherence to colonoscopy advice in the Dutch CRC screening program. SUBJECTS Non-adherent FIT-positive participants of the Dutch CRC screening program. DESIGN We conducted semi structured in-depth interviews with 17 persons who did not undergo colonoscopy within 6 months after a positive FIT. Interviews were undertaken face-to-face and data were analysed thematically with open coding and constant comparison. RESULTS All participants had multifactorial motives for non-adherence. A preference for more personalised care was described with the following themes: aversion against the design of the screening program, expectations of personalised care, emotions associated with experiences of impersonal care and a desire for counselling where options other than colonoscopy could be discussed. Furthermore, intrinsic motives were: having a perception of low risk for CRC (described by all participants), aversion and fear of colonoscopy, distrust, reluctant attitude to the treatment of cancer and cancer fatalism. Extrinsic motives were: having other health issues or priorities, practical barriers, advice from a general practitioner (GP) and financial reasons. CONCLUSION Personalised screening counselling might have helped to improve the interviewees' experiences with the screening program as well as their knowledge on CRC and CRC screening. Future studies should explore whether personalised screening counselling also has potential to increase adherence rates. Key points Participants with a positive FIT in two-step colorectal cancer (CRC) screening programs are at high risk for colorectal cancer and advanced adenomas. Non-adherence after an unfavourable screening result happens in all CRC programs worldwide with the consequence that many of the participants do not undergo colonoscopy for the definitive assessment of the presence of colorectal cancer. Little qualitative research has been done to study the reasons why individuals participate in the first step of the screening but not in the second step. We found a preference for more personalised care, which was not reported in previous literature on this subject. Furthermore, intrinsic factors, such as a low risk perception and distrust, and extrinsic factors, such as the presence of other health issues and GP advice, may also play a role in non-adherence. A person-centred approach in the form of a screening counselling session may be beneficial for this group of CRC screening participants.

Colorectal screening using the immunochemical faecal occult blood test kit among the Malaysian cohort participants. Cancer Epidemiol 2020; 65:101656. [PMID: 31923638 DOI: 10.1016/j.canep.2019.101656] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/22/2019] [Revised: 11/19/2019] [Accepted: 12/04/2019] [Indexed: 01/01/2023]
Abstract
BACKGROUND There has been a rapid increase in colorectal cancer (CRC) cases in Asian countries, including Malaysia. CRC is usually diagnosed at a late stage, and early detection of CRC is vital in improving survival. This study was conducted to determine the uptake rate of the immunochemical faecal occult blood test (iFOBT), the response rate to colonoscopy, and the CRC detection rate. We also wanted to identify the association between colorectal neoplasia and the Asia Pacific Colorectal Cancer Screening (APCS) scoring system. METHODS We recruited 2264 individuals from The Malaysian Cohort participants aged 35-65 years who consented to colorectal screening using the iFOBT kit from July 2017 until January 2019. RESULTS The response rate and positive iFOBT test rate of this study were 79.6% and 13.1% respectively. Among those with positive results, 125 individuals (52.7%) underwent colonoscopy; CRC was detected in six of them while 45 others (36.0%) had polyps. The overall CRC detection rate was 0.3% while the colorectal neoplasia detection rate (both colorectal cancer and colorectal polyps) was 2.3%. The APCS scoring indicated a significant association with colorectal neoplasia risk, with increasing trend by severity from moderate to high risk (3.46-11.14) compared to low risk. Most of the participants who were positive for iFOBT were those at high risk. CONCLUSIONS The awareness of CRC risk and iFOBT screening are important strategies for early detection of CRC. We showed a CRC detection rate of 0.3 % among those who volunteered to have the iFOBT screening.

Abstract
BACKGROUND AND AIM PBK-1701TC is a novel sulfate tablet-based that contains 320 mg of simethicone and delivers 90% of the salt and water delivered by oral sulfate solution (OSS) preparation. This study evaluated the efficacy, safety, and tolerability of PBK-1701TC compared with OSS in bowel preparation for colonoscopy. METHODS This randomized, multicenter, phase 3 non-inferiority trial included adults aged 19 years or older with a body mass index of 19-30 kg/m2 undergoing colonoscopy at five university hospitals in Korea. The primary efficacy endpoint was successful bowel-cleansing rate, defined as Harefield Cleansing Scale grade A or B as evaluated by blinded central readers. Secondary endpoints included the presence of residual air bubbles. Adverse events and laboratory evaluations were monitored to assess safety. Tolerability was assessed via participant interview. RESULTS Overall, 235 participants were randomized, and 224 were included in the per-protocol analysis (PBK, 112; OSS, 112). Successful bowel cleansing was achieved for 95.5% (107/112) in the PBK group, which was non-inferior to the OSS group (98.2%, 110/112) with a difference of -2.7% (one sided 97.5% confidence limit, -8.1%). The participants in the PBK group had fewer intraluminal bubbles (0.9% vs 81.3%, P < 0.001) and reported a lower incidence of nausea and vomiting, with better acceptance, taste, and willingness to repeat the regimen than those in the OSS group (all P < 0.05). CONCLUSION The novel sulfate tablet, PBK-1701TC, was non-inferior to OSS with respect to bowel-cleansing efficacy and exhibited better safety and tolerability in adults undergoing colonoscopy.
