Abstract
Heritable factors account for approximately 35% of colorectal cancer (CRC) risk, and almost 30% of the population in the UK have a family history of CRC. The quantification of an individual's lifetime risk of gastrointestinal cancer may incorporate clinical and molecular data, and depends on accurate phenotypic assessment and genetic diagnosis. In turn this may facilitate targeted risk-reducing interventions, including endoscopic surveillance, preventative surgery and chemoprophylaxis, which provide opportunities for cancer prevention. This guideline is an update from the 2010 British Society of Gastroenterology/Association of Coloproctology of Great Britain and Ireland (BSG/ACPGBI) guidelines for colorectal screening and surveillance in moderate and high-risk groups; however, this guideline is concerned specifically with people who have increased lifetime risk of CRC due to hereditary factors, including those with Lynch syndrome, polyposis or a family history of CRC. On this occasion we invited the UK Cancer Genetics Group (UKCGG), a subgroup within the British Society of Genetic Medicine (BSGM), as a partner to BSG and ACPGBI in the multidisciplinary guideline development process. We also invited external review through the Delphi process by members of the public as well as the steering committees of the European Hereditary Tumour Group (EHTG) and the European Society of Gastrointestinal Endoscopy (ESGE). A systematic review of 10 189 publications was undertaken to develop 67 evidence and expert opinion-based recommendations for the management of hereditary CRC risk. Ten research recommendations are also prioritised to inform clinical management of people at hereditary CRC risk.

Invitation to Screening Colonoscopy in the Population at Familial Risk for Colorectal Cancer. DEUTSCHES ARZTEBLATT INTERNATIONAL 2019; 115:715-722. [PMID: 30518470 DOI: 10.3238/arztebl.2018.0715] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/19/2018] [Revised: 01/19/2018] [Accepted: 05/30/2018] [Indexed: 12/13/2022]
Abstract
BACKGROUND Screening colonoscopy can lower the incidence of colorectal cancer (CRC), yet participation rates are low even in groups at high risk. The goal of this study was to double the rate of participation in screening colonoscopy among persons at familial risk and then to determine the frequency of neoplasia in this risk group. METHODS In a nationwide, cluster-randomized, multicenter study, first-degree relatives (FDR) of patients with CRC across Germany received written informational materials concerning the familial risk of CRC, along with an invitation to undergo colonoscopy. Participants in the intervention group were additionally counseled by nurses over the telephone. The primary endpoint of the study was colonoscopy uptake within 30 days. RESULTS The participants' mean age was 50.8 years. The colonoscopy uptake rates were 99/125 (79%) in the intervention group and 97/136 (71%) in the control group (RR = 1.11; 95% confidence interval [0.97; 1.28]). A polypectomy was performed in 72 of 196 asymptomatic persons (37%). In 13 cases (7%), an advanced neoplasia was detected; two of these persons had colon cancer (stages T0 and T1). 42% of the participants expressed barriers against colonoscopy. 22 reported mild side effects; there were no serious side effects. CONCLUSION Additional counseling by nurses over the telephone does not increase the participation rate. Approaching patients who have CRC is an opportunity to increase the participation of their first-degree relatives in screening colonoscopy. The frequency of neoplasia that was found in this study underscores the need to screen relatives even before they reach the usual age threshold for screening.

Lower Relative Contribution of Positive Family History to Colorectal Cancer Risk with Increasing Age: A Systematic Review and Meta-Analysis of 9.28 Million Individuals. Am J Gastroenterol 2018; 113:1819-1827. [PMID: 29867176 PMCID: PMC6768593 DOI: 10.1038/s41395-018-0075-y] [Citation(s) in RCA: 20] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/29/2017] [Accepted: 03/19/2018] [Indexed: 02/08/2023]
Abstract
OBJECTIVES Existing algorithms predicting the risk of colorectal cancer (CRC) assign a fixed score for family history of CRC. Whether the increased CRC risk attributed to family history of CRC was higher in younger patients remains inconclusive. We examined the risk of CRC associated with family history of CRC in first-degree relative (FDR) according to the age of index subjects (<40 vs. ≥40; <50 vs. ≥50; and <60 vs. ≥60 years). METHODS Ovid Medline, EMBASE, and gray literature from the reference lists of all identified studies were searched from their inception to March 2017. We included case-control/cohort studies that investigated the relationship between family history of CRC in FDR and prevalence of CRC. Two reviewers independently selected articles according to the PRISMA guideline. A random effects meta-analysis pooled relative risks (RR). RESULTS We analyzed 9.28 million subjects from 63 studies. A family history of CRC in FDR confers a higher risk of CRC (RR = 1.76, 95% CI = 1.57-1.97, p < 0.001). This increased risk was higher in younger individuals (RR = 3.29, 95% CI = 1.67-6.49 for <40 years versus RR = 1.42, 95% CI = 1.24-1.62 for ≥40 years, p = 0.017; RR = 2.81, 95% CI = 1.94-4.07 for <50 years versus RR = 1.47, 95% CI = 1.28-1.69 for ≥50 years, p = 0.001). No publication bias was identified, and the findings are robust in subgroup analyses. CONCLUSIONS The increase in relative risk of CRC attributed to family history was found to be higher in younger individuals. Family history of CRC could be assigned a higher score for younger subjects in CRC risk prediction algorithms. Future studies should examine if such approach may improve their predictive capability.

Utilization of colonoscopy and colonoscopic findings among individuals aged 40-54 years with a positive family history of colorectal cancer: a cross-sectional study in general practice. Eur J Cancer Prev 2017; 27:539-545.

Abstract
Guidelines recommend early colonoscopy for individuals with a positive family history of colorectal cancer (CRC), but little is known about the utilization of colonoscopy and the frequency of colorectal neoplasms among younger affected individuals in Germany. The aim of this study was to determine the utilization of colonoscopy and the frequency of colorectal neoplasms in this risk group. We conducted a cross-sectional study in a general practice setting. Patients aged 40-54 years with at least one first-degree relative with CRC were identified, counseled on their increased risk, and referred to colonoscopy if they decided to undergo this procedure. We assessed the reported utilization of colonoscopy before study participation with a questionnaire and obtained results of colonoscopies performed during the study period from colonoscopy reports. Out of 484 patients with a positive family history of CRC, 191 (39.5%) fulfilled the inclusion criteria and participated in the study: 54% reported that at least one colonoscopy had been performed before study participation. Out of 191 participants, 86 (45%) underwent a colonoscopy during study period. No CRC was found, but 16.3% had any adenoma, and 7.0% had advanced adenomas. Overall, 155 (82%) study participants underwent a colonoscopy either before or during the study period. The utilization of colonoscopies among participants was remarkably high even before study participation. This rate increased up to 82% after counseling by general practitioners. A relevant number of participants had (advanced) adenomas. It appears worthwhile to involve general practitioners in identifying and counseling younger individuals with familial risk for CRC.

Abstract
OBJECTIVES Colorectal cancer (CRC) is one of the most common malignancies worldwide. The aim of this study was to compare the outcomes of two different screening approaches in a small country (Montenegro, 650,000 inhabitants) with a CRC incidence lower than the European average. METHODS Two structured invitation programs were compared with respect to compliance and neoplasia yield: (i) program A focused on first-degree relatives of CRC patients diagnosed in two hospitals (n=206), inviting them for colonoscopy; (ii) program B was an invitation program for fecal occult blood testing, followed by colonoscopy if positive, conducted in University Hospital, Podgorica, Montenegro, on 2760 randomly selected average-risk persons, age 50-74 years, living in a single municipality. RESULTS Of 710 first-degree relatives of 206 CRC patients approached, 540 presented for colonoscopy (76.05% uptake). Overall, 31 were diagnosed with a cancer, 58 with advanced adenoma, and 151 with adenoma in general. In the general screening program, of 2760 individuals invited, 920 underwent fecal immunochemical test (33.3% uptake) and colonoscopy was performed in all 95 positive cases (10.3%); six cancers was found in five patients (one patient had two cancers), 19 patients were diagnosed with advanced adenoma, and 26 with any adenomas. The risk-targeted screening program had a significantly higher yield for cancers in both per invited (31/710 vs. 5/2760, P<0.001) and per eligible person analysis (31/540 vs. 5/920, P<0.001). CONCLUSION In a low-incidence country with limited resources, it may be advisable to start with CRC screening targeted to risk groups.

Abstract
AIM To combine community and hospital services in order to enable improvements in patient management, an integrated gastroenterology service (IGS) was established. METHODS Referral patterns to specialist clinics were optimized; open access route for endoscopic procedures (including esophago-gastro-duodenoscopy, sigmoidoscopy and colonoscopy) was established; family physicians' knowledge and confidence were enhanced; direct communication lines between experts and primary care physicians were opened. Continuing education, guidelines and agreed instructions for referral were promoted by the IGS. Six quality indicators were developed by the Delphi method, rigorously designed and regularly monitored. Improvement was assessed by comparing 2010, 2011 and 2012 indicators. RESULTS An integrated delivery system in a specific medical field may provide a solution to a fragmented healthcare system impaired by a lack of coordination. In this paper we describe a new integrated gastroenterology service established in April 2010. Waiting time for procedures decreased: 3 mo in April 30th 2010 to 3 wk in April 30th 2011 and stayed between 1-3 wk till December 30th 2012. Average cost for patient's visit decreased from 691 to 638 NIS (a decrease of 7.6%). Six health indicators were improved significantly comparing 2010 to 2012, 2.5% to 67.5%: Bone densitometry for patients with inflammatory bowel disease, preventive medications for high risk patients on aspirin/NSAIDs, colonoscopy following positive fecal occult blood test, gastroscopy in Barrett's esophagus, documentation of family history of colorectal cancer, and colonoscopy in patients with a family history of colorectal cancer. CONCLUSION Establishment of an IGS was found to effectively improve quality of care, while being cost-effective.

Abstract
BACKGROUND The role of a faecal immunochemical test (FIT) in screening individuals with a positive family history of colorectal cancer (CRC) is not clear. AIM To assess the diagnostic accuracy of FIT using colonoscopy findings as the gold standard in identifying colorectal neoplasms. METHODS We analysed data from 4539 asymptomatic subjects aged 50-70 years who had both colonoscopy and FIT (Hemosure; W.H.P.M., Inc, El Monte, CA, USA) at our bowel cancer screening centre between 2008 and 2012. A total of 572 subjects (12.6%) had a family history of CRC. Our primary outcome was the sensitivity of FIT in detecting advanced neoplasms and cancers in subjects with a family history of CRC. A family history of CRC was defined as any first-degree relative with a history of CRC. RESULTS Among 572 subjects with a family history of CRC, adenoma, advanced neoplasm and cancer were found at screening colonoscopy in 29.4%, 6.5% and 0.7% individuals, respectively. The sensitivity of FIT in detecting adenoma, advanced neoplasm and cancer was 9.5% [95% confidence interval (CI), 5.7-15.3], 35.1% (95% CI, 20.7-52.6) and 25.0% (95% CI, 1.3-78.1), respectively. Among FIT-negative subjects who have a family history of CRC, adenoma was found in 152 (29.6%), advanced neoplasm in 24 (4.7%) and cancer in 3 (0.6%) individuals. CONCLUSION Compared with colonoscopy, FIT is more likely to miss advanced neoplasms or cancers in individuals with a family history of CRC.

Abstract
Patients with a positive family history have an increased risk of colorectal cancer (CRC) and, in many countries, more intensive screening regimens, sometimes involving the use of colonoscopy as opposed to sigmoidoscopy or fecal occult blood testing, are recommended. This review discusses current screening guidelines in the United States and other countries, data on the magnitude of CRC risk in the presence of a family history and the efficacy of recommended screening programs, as well as ancillary issues such as compliance, cost-effectiveness and accuracy of family history ascertainment. We focus on the relatively common “sporadic” family histories of CRC, which typically imparts a mild to moderate elevation in the risk for CRC development in the proband. Defined familial syndromes associated with extremely high risks of CRC, such as hereditary non-polyposis colorectal syndrome or familial adenomatous polyposis, require specialized management approaches and are beyond the scope of this article. We will also not discuss colonoscopic surveillance in patients with a personal history of adenomas or CRC.

Abstract
BACKGROUND Per current guidelines, patients with a first-degree relative (FDR) with colorectal cancer (CRC) should get screened at least at age 40. Data about the prevalence of adenomas and advanced adenomas (AAs) in these patients are lacking. OBJECTIVE To examine the prevalence of adenomas and AAs in 40- to 49-year-old individuals undergoing screening colonoscopy for family history of CRC. DESIGN Retrospective chart review. PATIENTS Asymptomatic patients 40 to 49 years of age undergoing their first screening colonoscopy at the University of Michigan during the period 1999 to 2009 because of an FDR with CRC. MAIN OUTCOME MEASUREMENTS Prevalence of adenomas (any size), AAs, and risk factors associated with adenomas. RESULTS Among 640 study patients, the prevalence of adenomas (any size) was 15.4% and 3.3% for AAs. Adenoma prevalence was lower if the FDR with CRC was younger than 60 years of age versus an FDR with CRC older than 60 years of age (12.4% vs 19%, P = .034). Male sex (odds ratio 2.6; 95% CI, 1.06-4.4) and advancing age (odds ratio 1.16; 95% CI, 1.03-1.31) were associated with adenomas. LIMITATIONS Limited data on risk factor exposure and insufficient sample size to assess risk factors for AAs. CONCLUSIONS Among 40- to 49-year-old patients undergoing screening colonoscopy because of an FDR with CRC, the prevalence of adenomas and AAs is low. Further research should determine whether these individuals have a higher prevalence of adenomas compared with average-risk individuals.

Abstract
BACKGROUND A screening colonoscopy is recommended in first-degree relatives (FDRs) of colorectal cancer patients; few prospective, controlled studies have evaluated colorectal findings in a population-based screening program. OBJECTIVE To evaluate the prevalence of colorectal neoplasia (adenomas and adenocarcinomas) in this increased-risk population, to compare it with that of average-risk individuals, and to identify features that might allow risk stratification for neoplasia among FDRs. DESIGN Cross-sectional study. SETTING Population-based screening program in Trentino, Italy. PATIENTS FDRs of colorectal cancer patients between 45 and 75 years of age with no history of hereditary colorectal cancer syndromes or inflammatory bowel disease. CONTROLS Average-risk individuals undergoing screening colonoscopy. INTERVENTION Screening colonoscopy. RESULTS Neoplasia was found in 33.4% of 1252 FDRs and in 30.3% of 765 controls; advanced neoplasia was found in 11.3% of FDRs and in 6.3% of controls. Odds ratios (ORs) from the multivariate logistic regression analysis adjusted for age, sex, cecal intubation rates, and colon cleansing showed an increased risk of advanced neoplasia (OR 2.41; 95% CI, 1.69-3.43; P < .0001) in FDRs. Age older than 56 years (OR 1.83; 95% CI, 1.15-2.99; P = .013) and male sex (OR 2.17; 95% CI, 1.39-3.10; P < .001) are independent predictors of advanced neoplasia. LIMITATIONS Italian subjects living in the same geographic area; of 4301 FDRs, 2521 were excluded. CONCLUSIONS The increased risk of advanced neoplasia supports the current recommendation for colonoscopic screening in this group; age and sex may assist in risk stratification of these individuals.

A decision-analytic evaluation of the cost-effectiveness of family history-based colorectal cancer screening programs. Am J Gastroenterol 2010; 105:1861-9.

Abstract
OBJECTIVES The aim of this study was to determine the cost-effectiveness of family history screening (FHS) for colorectal cancer (CRC) susceptibility at age 40 with early screening of those with increased risk. METHODS The cost-effectiveness of several family history-based screening programs was estimated with a validated microsimulation model, using data from the SEER cancer registry, life tables, medicare records, and published data. Familial cancer syndromes were excluded. Screening programs evaluated included (i) colonoscopy screening every 10 years starting at age 50 (no family history assessment); (ii) colonoscopy every 10 years from age 40 for persons with a family history; (iii) colonoscopy every 5 years from age 50 for those with a family history; and (iv) colonoscopy every 5 years from age 40 for persons with a family history. In each FHS scenario, persons without a family history are screened with colonoscopy at age 50, then every 10 years to age 80. RESULTS Compared with colonoscopy screening of all persons from age 50, the cost-effectiveness of the family history-based screening programs varied from $18,000-$51,000 per life year (LY) gained. Screening family history cases every 5 years from age 40 is more cost-effective than screening every 10 years from age 40. Reducing screening frequency for those without a family history lowers program expenditures substantially at a modest loss of LYs. The results are sensitive to the CRC risk difference between positive and negative family histories. CONCLUSIONS The cost-effectiveness of CRC FHS guidelines varies widely. Economic issues should be considered before implementing family history-directed screening programs.

Abstract
This study examined psychosocial factors influencing colorectal cancer (CRC) patients' communication with their first-degree relatives regarding their CRC risk. Among a sample of CRC patients who were members of a colon registry in New York (n = 127), 60% reported discussing CRC risk with their siblings. These discussions were related to the CRC patients' age of diagnosis, such that those diagnosed before age 45 years were more likely to communicate with their siblings about CRC risk. Despite advances made in CRC prevention, compliance with screening recommendations among individuals who may be at familial risk for the disease is low. Perhaps this underrepresentation reflects how CRC patients communicate with their first-degree relatives about their potential risk for the disease. This study examined the psychosocial factors influencing whether CRC patients communicate with their siblings about CRC risk. The sample included CRC patients with siblings who enrolled in a colon disease registry at a NYC metropolitan hospital. Participants completed questionnaires regarding their current psychosocial functioning, perceived risk of sibling's development of CRC, and communication of CRC risk with their siblings. Patients were predominantly Caucasian, with a mean age of 60.4 years. Of the 127 patients, 60% engaged in discussions with their siblings regarding their CRC risk. Patients diagnosed with CRC before the age of 45 years were more likely to discuss the risk of CRC with their siblings (P < 0.01). These data suggest that CRC patients may serve as an effective vehicle to promote CRC screening and support the need for health care providers to not only educate patients of the familial risk of CRC, but to also encourage these patients to communicate this information with their siblings.

Abstract
PURPOSE Proctocolectomy with ileoanal pouch construction is the standard therapy for patients with familial adenomatous polyposis coli (FAP) to prevent the genesis of colorectal carcinomas. In our patient population, we observed the postoperative development of adenomas not only in the pouch but also in the remaining small intestine. The exact incidence of these ileal polyps is still unknown, since the diagnostic possibilities of examining the small intestine are limited. METHODS We performed wireless capsule endoscopy (CE) in patients who developed postoperative pouch adenomas (PA) to record the simultaneous occurrence of small bowel adenomas and PA. We operated on 46 patients with FAP (m:f 17:10, age 33 +/- 9 years). Thirty-five patients underwent proctocolectomy with ileoanal pouch creation. Pouch endoscopy was performed in regular intervals at 3 months and then annually after proctocolectomy. Capsule endoscopy was additionally carried out in all patients with PA. RESULTS Ileal PA occurred in 22.8% (n = 8) of the patients with proctocolectomy (n = 35) after a mean of 5 years after surgery. Eight PA patients (all with PA) also had adenomas in the small intestine diagnosed by CE. CONCLUSIONS Since jejunal and ileal adenomas occur in all patients with PA, we recommend regular follow-up examinations, which include pouch endoscopy at 3 months and annually after surgery in the presence of PA after proctocolectomy and pouch creation. On the basis of our observations, we recommend adding CE or double-balloon enteroscopy to the follow-up examination.

Abstract
BACKGROUND Retrieving colorectal polyp after endoscopic snare polypectomy is time consuming and possibly incurs a failure. The aim of the study was to assess the effectiveness of the multiple-suction (M-S) technique for retrieving a variety of polyps. MATERIALS AND METHODS Four hundred and nine cases received endoscopic snare polypectomy from January 2003 to January 2007 were reviewed. The resected polyps were retrieved by M-S technique, in which suction regarded as the leading technique, was taken in combination with channel occlusion, trap, snare, and grasping forcep. Time of cecal intubation and of polypectomy, total examination time, shape, size, location, and number of polyp(s) were recorded. Retrieval time and polyp lost rate were also noted. RESULTS A total of 602 polyps more than 3 mm in diameter underwent snare polypectomy. There were 96.7% (582/602) of polyps retrieved by the M-S technique. The mean retrieval time was 1.5 +/- 0.6 min. Time of polypectomy, retrieval time, and total examination time were significantly positive correlative with the number of polyps (P < 0.05). In a univariate analysis, longer retrieval time was significantly associated with larger polyps, more distant polyps from the anus, and a greater number of polyps, while higher polyp lost rate was significantly associated with sessile polyp, smaller polyps, and a greater number of polyps. In a multivariate analysis, retrieval time level (< or = 2.0 or >2.0 min) was linked to the number of polyps. CONCLUSIONS The M-S technique is proved to be reliable when used in the majority cases of colorectal polyp retrieval. In retrieving too many polyps, the M-S technique is time consuming, and hence, additional methods should be applied to improve its retrieval effectiveness.

Colorectal cancer screening: results of a 5-year program in asymptomatic subjects at increased risk. Dig Liver Dis 2007; 39:33-9. [PMID: 17049323 DOI: 10.1016/j.dld.2006.09.001] [Citation(s) in RCA: 16] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/08/2005] [Revised: 08/16/2006] [Accepted: 09/05/2006] [Indexed: 02/06/2023]
Abstract
BACKGROUND AND AIMS The province of Ferrara has one of the highest incidences of colorectal cancer (CRC) in Italy. In January 2000, we set up a colonoscopy screening program focussing on first-degree relatives of CRC patients. We now report the results 5 years after the beginning of the project. SCREENEES AND METHODS: In October 1999, we started a campaign stressing the usefulness of colonoscopy for the first-degree relatives of CRC patients. Subjects included in the screening program were aged between 45 and 75 years with at least one first-degree relative affected by CRC. They were invited to an interview where a physician suggested colonoscopy as a screening option. RESULTS In 5 years, 776 subjects were interviewed and 733 (94.4%) agreed to an endoscopic examination (M/F:375/401; mean age 55 years): 562 colonoscopies were performed. Adenomas and cancers were found in 122 (21.7%) and 12 (2.1%) subjects, respectively. Histological examination in 181 persons with lesions (32.8%) showed (most serious lesion quoted) 47 hyperplastic polyps (26% of all lesions), 2 serrated adenomas (1.1%), 68 tubular adenomas (48%), 24 tubulovillous adenomas (13.3%), 9 adenomas with high grade dysplasia (5%) and 12 adenocarcinomas (6.6%). The majority of the cancers were at an early stage (8 Dukes A and 3 Dukes B). Sedation was used in only 42 colonoscopies (7.5%). CONCLUSIONS A colonoscopy-based screening in this selected high-risk population is feasible. Even without sedation subjects readily agreed to the endoscopic procedure. We identified a significant number of advanced neoplasms and cancers at an early stage suggesting that this could be a useful tool in early identification of CRC.

Abstract
BACKGROUND AND AIMS As shown previously, 40- to 50-year-old first-degree relatives of patients with colorectal cancer (CRC) have significantly more colorectal adenomas than controls of the same age. Screening colonoscopy of these persons at risk between 40 and 50 years might be cost beneficial. METHODS We prepared a detailed cost-benefit analysis of screening colonoscopy and possible repeat endoscopies according to current expenditures for endoscopic procedures in Germany. Since screening colonoscopy is generally offered and reimbursed from 55 years on in Germany, we analysed the period between 45 and 55 years, taking an annual interest rate of 5% into account. Costs were analysed based on the results of a former study [11] depending on various participation rates in a general screening programme. FINDINGS Based on the available 1994 figure of about 20,000 euros for diagnosis and treatment of one cancer case, screening colonoscopy is cost beneficial when participation is high. Under a more realistic assumption of currently about 40,000 euros per cancer case, screening colonoscopy is cost beneficial in any case. INTERPRETATION Our data support that systematic screening colonoscopy in first-degree relatives of patients with CRC by the age of 45 years most likely demonstrates an economic benefit.
