Feasibility and efficacy of a novel audiovisual tool to increase colorectal cancer screening among rural Appalachian Kentucky adults. Front Public Health 2024; 12:1415607. [PMID: 39056077 PMCID: PMC11269215 DOI: 10.3389/fpubh.2024.1415607] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/10/2024] [Accepted: 06/28/2024] [Indexed: 07/28/2024] Open
Abstract
Introduction Residents of Appalachian regions in Kentucky experience increased colorectal cancer (CRC) incidence and mortality. While population-based screening methods, such as fecal immunochemical tests (FITs), can reduce many screening barriers, written instructions to complete FIT can be challenging for some individuals. We developed a novel audiovisual tool ("talking card") to educate and motivate accurate FIT completion and assessed its feasibility, acceptability, and efficacy. Materials and methods We collected data on the talking card via: (1) cross-sectional surveys exploring perceptions of images, messaging, and perceived utility; (2) follow-up focus groups centered on feasibility and acceptability; and (3) efficacy testing in community-based FIT distribution events, where we assessed FIT completion rate, number of positive vs. negative screens, demographic characteristics of participants, and primary drivers of FIT completion. Results Across the three study phases, 692 individuals participated. Survey respondents positively identified with the card's sounds and images, found it highly acceptable, and reported high-to-very high self-efficacy and response efficacy for completing FIT, with nearly half noting greater likelihood to complete screening after using the tool. Focus group participants confirmed the acceptability of the individuals featured on the card. Nearly 75% of participants provided a FIT accurately completed it, with most indicating the talking card, either alone or combined with another strategy, helped with completion. Discussion To reduce CRC screening disparities among Appalachian Kentuckians, population-based screening using contextually relevant implementation strategies must be used alongside clinic-based education. The talking card represents a novel and promising strategy to promote screening uptake in both clinical and community settings.

J Community Genet 2024; 15:217-234. [PMID: 38769249 PMCID: PMC11217210 DOI: 10.1007/s12687-024-00709-8] [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: 12/11/2023] [Accepted: 05/02/2024] [Indexed: 05/22/2024] Open
Abstract
BACKGROUND Polygenic scores (PGS) have been developed for cancer risk-estimation and show potential as tools to prompt earlier referral for high-risk individuals and aid risk-stratification within cancer screening programmes. This review explores the potential for using PGS to identify individuals at risk of the most common cancers seen in primary care. METHODS Two electronic databases were searched up until November 2023 to identify quantitative, qualitative, and mixed methods studies that reported on the acceptability and clinical impact of using PGS to identify individuals at highest risk of breast, prostate, colorectal and lung cancer in primary care. The Mixed Methods Appraisal Tool (MMAT) was used to assess the quality of included studies and a narrative synthesis was used to analyse data. RESULTS A total of 190 papers were identified, 18 of which were eligible for inclusion. A cancer risk-assessment tool incorporating PGS was acceptable to the general practice population and their healthcare providers but major challenges to implementation were identified, including lack of evidence for PGS in non-European ancestry and a need for healthcare provider education in genomic medicine. A PGS cancer risk-assessment had relatively limited impact on psychosocial outcomes and health behaviours. However, for prostate cancer, potential applications for its use in primary care were shown. CONCLUSIONS Cancer risk assessment incorporating PGS in primary care is acceptable to patients and healthcare providers but there is a paucity of research exploring clinical impact. Few studies were identified, and more research is required before clinical implementation of PGS can be recommended.

Abstract
Risk-based genetic tests are often used to determine cancer risk, when to initiate screening, and frequency of screening, but rely on interest in genetic testing. We examined overall interest in genetic testing for cancer risk assessment and willingness to change behavior, and whether these are affected by demographic or socioeconomic factors.We conducted a community needs health survey in 2019 among primary care and cancer patients, family members and community members in New York City. We used univariable analysis and relative risk regression to examine interest in genetic cancer risk testing and willingness to modify lifestyle behaviors in response to an informative genetic test.Of the 1225 participants, 74.0% (n = 906) expressed interest in having a genetic test to assess cancer risk. Interest in genetic testing was high across all demographic and socioeconomic groups; reported interest in genetic testing by group ranged from 65.0 (participants aged 65 years and older) to 83.6% (participants below federal poverty level). Among the 906 participants that reported interest in genetic testing, 79.6% were willing to change eating habits, 66.5% to change exercise habits, and 49.5% to lose weight in response to an informative genetic test result.Our study reveals that interest in genetic testing for cancer risk is high among patients and community members and is high across demographic and socioeconomic groups, as is the reported willingness to change behavior. Based on these results, we recommend that population-based genetic testing may result in greater reduction cancer risk, particularly among minoritized groups.

Abstract
Background Polygenic risk scores (PRSs) can predict the risk of colorectal cancer (CRC) and target screening more precisely than current guidelines using age and family history alone. Primary care, as a far-reaching point of healthcare and routine provider of cancer screening and risk information, may be an ideal location for their widespread implementation. Methods This trial aims to determine whether the SCRIPT intervention results in more risk-appropriate CRC screening after 12 months in individuals attending general practice, compared with standard cancer risk reduction information. The SCRIPT intervention consists of a CRC PRS, tailored risk-specific screening recommendations and a risk report for participants and their GP, delivered in general practice. Patients aged between 45 and 70 inclusive, attending their GP, will be approached for participation. For those over 50, only those overdue for CRC screening will be eligible to participate. Two hundred and seventy-four participants will be randomised to the intervention or control arms, stratified by general practice, using a computer-generated allocation sequence. The primary outcome is risk-appropriate CRC screening after 12 months. For those in the intervention arm, risk-appropriate screening is defined using PRS-derived risk; for those in the control arm, it is defined using family history and national screening guidelines. Timing, type and results of the previous screening are considered in both arms. Objective health service data will capture screening behaviour. Secondary outcomes include cancer-specific worry, risk perception, predictors of CRC screening behaviour, screening intentions and health service use at 1, 6 and 12 months post-intervention delivery. Discussion This trial aims to determine whether a PRS-derived personalised CRC risk estimate delivered in primary care increases risk-appropriate CRC screening. A future population risk-stratified CRC screening programme could incorporate risk assessment within primary care while encouraging adherence to targeted screening recommendations.

Abstract
Background: The integration of genetic testing into eHealth applications holds great promise for the personalization of disease prevention guidelines. However, relatively little is known about the impact of eHealth applications on an individual's behavior. Aim: The aim of the pilot study was to investigate the effect of the personalized eHealth application approach to behavior change in a 1-month follow-up period on groups with previously known and unknown caffeine impacts. Method: We created a direct-to-consumer approach that includes providing relevant information and personalized reminders and goals on the digital device regarding the caffeine intake for two groups of individuals: the intervention group (IG) with the genetic raw data available and the control group (CG) to test the impact of the same content (article about caffeine metabolism) on participants without the genetic test. Study participants were all Estonians (n = 160). Results: The study suggests that eHealth applications work for short-term behavior change. Participants in the genetic IG tended to increase caffeine intake if they were informed about caffeine not being harmful. They reported feeling better physically and/or mentally after their behavioral change decision during the period of the study. Conclusions: Our pilot study revealed that eHealth applications may have a positive effect for short-term behavior change, regardless of a prior genetic test. Further studies among larger study groups are required to achieve a better understanding about behavior change of individuals in the field of personalized medicine and eHealth interventions.

Genetic counselling for the prevention of mental health consequences of cannabis use: A randomized controlled trial-within-cohort. Early Interv Psychiatry 2021; 15:1306-1314.

Abstract
BACKGROUND Cannabis use is a risk factor for severe mental illness. However, cannabis does not affect everyone equally. Genetic information may help identify individuals who are more vulnerable to the harmful effects of cannabis on mental health. A common genetic variant within the AKT1 gene selectively increases risk of psychosis, only among those who use cannabis. Therapeutically oriented genetic counselling may enable us to reduce cannabis exposure among genetically sensitive individuals. METHODS Using a trial-within-cohort design, we aim to test if genetic counselling, including the option to receive AKT1 rs2494732 genotype, reduces cannabis use. To this end, we have designed a genetic counselling intervention: Interdisciplinary approach to Maximize Adolescent potential: Genetic counselling Intervention to reduce Negative Environmental effects (IMAGINE). RESULTS IMAGINE will be implemented in a cohort of children and youth enriched for familial risk for major mood and psychotic disorders. Approximately 110 eligible individuals aged 12-21 years will be randomized in a 1:1 ratio to be offered a single genetic counselling session with a board-certified genetic counsellor, or not. Allocated youth will also be invited to attend a follow-up session approximately 1 month following the intervention. The primary outcome will be cannabis use (measured by self-report or urine screen) at subsequent annual assessments as part of the larger cohort study. Secondary outcomes include intervention acceptability and psychopathology. CONCLUSION This study represents the first translational application of a gene-environment interaction to improve mental health and test an intervention with potential public health benefits. This study is registered with clinicaltrials.gov (NCT03601026).

Abstract
Background The Breast and Ovarian Analysis of Disease Incidence and Carrier Estimation Algorithm and the International Breast Cancer Intervention Study breast cancer risk models are used to provide advice on screening intervals and chemoprevention. We evaluated the performance of these models, which now incorporate polygenic risk scores (PRSs), using a prospective cohort study. Methods We used a case-cohort design, involving women in the Melbourne Collaborative Cohort Study aged 50-75 years when surveyed in 2003-2007, of whom 408 had a first primary breast cancer diagnosed within 10 years (cases), and 2783 were from the subcohort. Ten-year risks were calculated based on lifestyle factors, family history data, and a 313-variant PRS. Discrimination was assessed using a C-statistic compared with 0.50 and calibration using the ratio of expected to observed number of cases (E/O). Results When the PRS was added to models with lifestyle factors and family history, the C-statistic (95% confidence interval [CI]) increased from 0.57 (0.54 to 0.60) to 0.62 (0.60 to 0.65) using IBIS and from 0.56 (0.53 to 0.59) to 0.62 (0.59 to 0.64) using BOADICEA. IBIS underpredicted risk (E/O = 0.62, 95% CI = 0.48 to 0.80) for women in the lowest risk category (<1.7%) and overpredicted risk (E/O = 1.40, 95% CI = 1.18 to 1.67) in the highest risk category (≥5%), using the Hosmer-Lemeshow test for calibration in quantiles of risk and a 2-sided P value less than .001. BOADICEA underpredicted risk (E/O = 0.82, 95% CI = 0.67 to 0.99) in the second highest risk category (3.4%-5%); the Hosmer-Lemeshow test and a 2-sided P value was equal to .02. Conclusions Although the inclusion of a 313 genetic variant PRS doubles discriminatory accuracy (relative to reference 0.50), models with and without this PRS have relatively modest discrimination and might require recalibration before their clinical and wider use are promoted.

Abstract
INTRODUCTION Risk stratification has been proposed as a strategy to improve participation in colorectal cancer (CRC) screening, but evidence is lacking. We performed a randomized controlled trial of risk stratification using the National Cancer Institute's Colorectal Cancer Risk Assessment Tool (CCRAT) on screening intent and completion. METHODS A total of 230 primary care patients eligible for first-time CRC screening were randomized to risk assessment via CCRAT or education control. Follow-up of screening intent and completion was performed by record review and phone at 6 and 12 months. We analyzed change in intent after intervention, time to screening, overall screening completion rates, and screening completion by CCRAT risk score tertile. RESULTS Of the patients, 61.7% of patients were aged <60 years, 58.7% female, and 94.3% with college or higher education. Time to screening did not differ between arms (hazard ratio 0.78 [95% confidence interval (CI) 0.52-1.18], P = 0.24). At 12 months, screening completion was 38.6% with CCRAT vs 44.0% with education (odds ratio [OR] 0.80 [95% CI 0.47-1.37], P = 0.41). Changes in screening intent did not differ between the risk assessment and education arms (precontemplation to contemplation: OR 1.52 [95% CI 0.81-2.86], P = 0.19; contemplation to precontemplation: OR 1.93 [95% CI 0.45-8.34], P = 0.38). There were higher screening completion rates at 12 months in the top CCRAT risk tertile (52.6%) vs the bottom (32.4%) and middle (31.6%) tertiles (P = 0.10). DISCUSSION CCRAT risk assessment did not increase screening participation or intent. Risk stratification might motivate persons classified as higher CRC risk to complete screening, but unintentionally discourage screening among persons not identified as higher risk.

METHODS Participants aged 45-74 years recruited from 4 Australian general practices were offered a genomic CRC risk test. Participants received brief verbal information about the test comprising 45 CRC-associated single-nucleotide polymorphisms, before choosing whether to undertake the test. Personalized risks were given to testers. Uptake and knowledge of the genomic test, cancer-specific anxiety (Cancer Worry Scale), psychosocial impact (Multidimensional Impact of Cancer Risk Assessment [MICRA] score), and impact on CRC screening behaviour within 6 months were measured. RESULTS In 150 participants, test uptake was high (126, 84%), with 125 (83%) having good knowledge of the genomic test. Moderate risk participants were impacted more by the test (MICRA mean: 15.9) than average risk participants (mean: 9.5, difference in means: 6.4, 95% confidence interval (CI): 1.5, 11.2, p = 0.01), but all scores were low. Average risk participants' cancer-specific anxiety decreased (mean differences from baseline: 1 month -0.5, 95% CI: -1.0, -0.1, p = 0.03; 6 months -0.6, 95% CI: -1.0, -0.2, p = 0.01). We found limited evidence for genomic testers being more likely to complete the risk-appropriate CRC screening than non-testers (41 vs. 17%, odds ratio = 3.4, 95% CI: 0.6, 34.8, p = 0.19), but some mediators of screening behaviour were altered in genomic testers. CONCLUSIONS Genomic testing for CRC risk in primary care is acceptable and likely feasible. Further development of the risk assessment intervention could strengthen the impact on screening behaviour.

Abstract
Pharmacogenetics and biomarkers are becoming normalised as important technologies to improve drug efficacy rates, reduce the incidence of adverse drug reactions, and make informed choices for targeted therapies. However, their wider clinical implementation has been limited by a lack of robust evidence. Suitable evidence is required before a biomarker's clinical use, and also before its use in a clinical trial. We have undertaken a review of five pharmacogenetic biomarker-guided randomised controlled trials (RCTs) and evaluated the evidence used by these trials to justify biomarker inclusion. We assessed and quantified the evidence cited in published rationale papers, or where these were not available, obtained protocols from trial authors. Very different levels of evidence were provided by the trials. We used these observations to write recommendations for future justifications of biomarker use in RCTs and encourage regulatory authorities to write clear guidelines.

Abstract
The purpose of this study was to develop a brief instrument, the Feelings About genomiC Testing Results (FACToR), to measure the psychosocial impact of returning genomic findings to patients in research and clinical practice. To create the FACToR, we modified and augmented the Multidimensional Impact of Cancer Risk Assessment (MICRA) questionnaire based on findings from a literature review, two focus groups (N = 12), and cognitive interviews (N = 6). We evaluated data from 122 participants referred for evaluation for inherited colorectal cancer or polyposis from the New EXome Technology in (NEXT) Medicine Study, an RCT of exome sequencing versus usual care. We assessed floor and ceiling effects of each item, conducted principal component analysis to identify subscales, and evaluated each subscale's internal consistency, test-retest reliability, and construct validity. After excluding items that were ambiguous or demonstrated floor or ceiling effects, 12 items forming four distinct subscales were retained for further analysis: negative emotions, positive feelings, uncertainty, and privacy concerns. All four showed good internal consistency (0.66-0.78) and test-retest reliability (0.65-0.91). The positive feelings and the uncertainty subscales demonstrated known-group validity. The 12-item FACToR with four subscales shows promising psychometric properties on preliminary evaluation in a limited sample and needs to be evaluated in other populations.

Abstract
IMPORTANCE Colorectal cancer screening (CRC) is recommended by all major US medical organizations but remains underused. OBJECTIVE To identify interventions associated with increasing CRC screening rates and their effect sizes. DATA SOURCES PubMed, Cumulative Index to Nursing and Allied Health Literature, the Cochrane Library, and ClinicalTrials.gov were searched from January 1, 1996, to August 31, 2017. Key search terms included colorectal cancer and screening. STUDY SELECTION Randomized clinical trials of US-based interventions in clinical settings designed to improve CRC screening test completion in average-risk adults. DATA EXTRACTION AND SYNTHESIS At least 2 investigators independently extracted data and appraised each study's risk of bias. Where sufficient data were available, random-effects meta-analysis was used to obtain either a pooled risk ratio (RR) or risk difference (RD) for screening completion for each type of intervention. MAIN OUTCOMES AND MEASURES The main outcome was completion of CRC screening. Examination included interventions to increase completion of (1) initial CRC screening by any recommended modality, (2) colonoscopy after an abnormal initial screening test result, and (3) continued rounds of annual fecal blood tests (FBTs). RESULTS The main review included 73 randomized clinical trials comprising 366 766 patients at low or medium risk of bias. Interventions that were associated with increased CRC screening completion rates compared with usual care included FBT outreach (RR, 2.26; 95% CI, 1.81-2.81; RD, 22%; 95% CI, 17%-27%), patient navigation (RR, 2.01; 95% CI, 1.64-2.46; RD, 18%; 95% CI, 13%-23%), patient education (RR, 1.20; 95% CI, 1.06-1.36; RD, 4%; 95% CI, 1%-6%), patient reminders (RR, 1.20; 95% CI, 1.02-1.41; RD, 3%; 95% CI, 0%-5%), clinician interventions of academic detailing (RD, 10%; 95% CI, 3%-17%), and clinician reminders (RD, 13%; 95% CI, 8%-19%). Combinations of interventions (clinician interventions or navigation added to FBT outreach) were associated with greater increases than single components (RR, 1.18; 95% CI, 1.09-1.29; RD, 7%; 95% CI, 3%-11%). Repeated mailed FBTs with navigation were associated with increased annual FBT completion (RR, 2.09; 95% CI, 1.91-2.29; RD, 39%; 95% CI, 29%-49%). Patient navigation was not associated with colonoscopy completion after an initial abnormal screening test result (RR, 1.21; 95% CI, 0.92-1.60; RD, 14%; 95% CI, 0%-29%). CONCLUSIONS AND RELEVANCE Fecal blood test outreach and patient navigation, particularly in the context of multicomponent interventions, were associated with increased CRC screening rates in US trials. Fecal blood test outreach should be incorporated into population-based screening programs. More research is needed on interventions to increase adherence to continued FBTs, follow-up of abnormal initial screening test results, and cost-effectiveness and other implementation barriers for more intensive interventions, such as navigation.

Effectiveness of personal genomic testing for disease-prevention behavior when combined with careful consultation with a physician: a preliminary study. BMC Res Notes 2018; 11:223.

Abstract
Objectives There are many direct-to-consumer (DTC)-type personal genomic testing (PGT) services commercially available to the public, providing the specific disease susceptibilities of individuals. While these services do not appear to stimulate disease-prevention behavior, few studies have addressed the methods to do so. We investigated the effectiveness of combining a consultation with a physician with the delivery of test results from a DTC-type PGT, as a preliminary study to identify the effective genomic testing for disease-prevention. A prepared physician disclosed the PGT results of twenty healthy subjects and provided a specific consultation on the high-risk diseases for each subject. The effects on the sense of health, understanding of possible future diseases, and preventive behaviors for each subject were examined pre-PGT, post-PGT, and 3, 6, and 12 months post-PGT. Results Significant increases between the pre- and post-PGT scores were observed for the awareness of lifestyle effects on developing those diseases (P < 0.05) and the awareness of the ability to influence disease onset (P < 0.01). The follow-up questionnaire results showed that over 60% of the subjects changed their lifestyles in favor of disease prevention. These results suggest that combining the DTC-PGT with a careful physician consultation may be effective at motivating people toward preventive behavior.

Abstract
OBJECTIVE Colorectal cancer (CRC) leads to significant morbidity/mortality worldwide. Defining critical research gaps (RG), their prioritisation and resolution, could improve patient outcomes. DESIGN RG analysis was conducted by a multidisciplinary panel of patients, clinicians and researchers (n=71). Eight working groups (WG) were constituted: discovery science; risk; prevention; early diagnosis and screening; pathology; curative treatment; stage IV disease; and living with and beyond CRC. A series of discussions led to development of draft papers by each WG, which were evaluated by a 20-strong patient panel. A final list of RGs and research recommendations (RR) was endorsed by all participants. RESULTS Fifteen critical RGs are summarised below: RG1: Lack of realistic models that recapitulate tumour/tumour micro/macroenvironment; RG2: Insufficient evidence on precise contributions of genetic/environmental/lifestyle factors to CRC risk; RG3: Pressing need for prevention trials; RG4: Lack of integration of different prevention approaches; RG5: Lack of optimal strategies for CRC screening; RG6: Lack of effective triage systems for invasive investigations; RG7: Imprecise pathological assessment of CRC; RG8: Lack of qualified personnel in genomics, data sciences and digital pathology; RG9: Inadequate assessment/communication of risk, benefit and uncertainty of treatment choices; RG10: Need for novel technologies/interventions to improve curative outcomes; RG11: Lack of approaches that recognise molecular interplay between metastasising tumours and their microenvironment; RG12: Lack of reliable biomarkers to guide stage IV treatment; RG13: Need to increase understanding of health related quality of life (HRQOL) and promote residual symptom resolution; RG14: Lack of coordination of CRC research/funding; RG15: Lack of effective communication between relevant stakeholders. CONCLUSION Prioritising research activity and funding could have a significant impact on reducing CRC disease burden over the next 5 years.

Psychological and behavioural impact of returning personal results from whole-genome sequencing: the HealthSeq project. Eur J Hum Genet 2017; 25:280-292. [PMID: 28051073 PMCID: PMC5315514 DOI: 10.1038/ejhg.2016.178] [Citation(s) in RCA: 44] [Impact Index Per Article: 6.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/10/2015] [Revised: 10/18/2016] [Accepted: 11/01/2016] [Indexed: 11/29/2022] Open
Abstract
Providing ostensibly healthy individuals with personal results from whole-genome sequencing could lead to improved health and well-being via enhanced disease risk prediction, prevention, and diagnosis, but also poses practical and ethical challenges. Understanding how individuals react psychologically and behaviourally will be key in assessing the potential utility of personal whole-genome sequencing. We conducted an exploratory longitudinal cohort study in which quantitative surveys and in-depth qualitative interviews were conducted before and after personal results were returned to individuals who underwent whole-genome sequencing. The participants were offered a range of interpreted results, including Alzheimer's disease, type 2 diabetes, pharmacogenomics, rare disease-associated variants, and ancestry. They were also offered their raw data. Of the 35 participants at baseline, 29 (82.9%) completed the 6-month follow-up. In the quantitative surveys, test-related distress was low, although it was higher at 1-week than 6-month follow-up (Z=2.68, P=0.007). In the 6-month qualitative interviews, most participants felt happy or relieved about their results. A few were concerned, particularly about rare disease-associated variants and Alzheimer's disease results. Two of the 29 participants had sought clinical follow-up as a direct or indirect consequence of rare disease-associated variants results. Several had mentioned their results to their doctors. Some participants felt having their raw data might be medically useful to them in the future. The majority reported positive reactions to having their genomes sequenced, but there were notable exceptions to this. The impact and value of returning personal results from whole-genome sequencing when implemented on a larger scale remains to be seen.

Abstract
BACKGROUND Prostate-specific antigen (PSA) screening may reduce death due to prostate cancer but leads to the overdiagnosis of many cases of indolent cancer. Targeted use of PSA screening may reduce overdiagnosis. Multimarker genomic testing shows promise for risk assessment and could be used to target PSA screening. METHODS To test whether counseling based on the family history (FH) and counseling based on a genetic risk score (GRS) plus FH would differentially affect subsequent PSA screening at 3 months (primary outcome), a randomized trial of FH versus GRS plus FH was conducted with 700 whites aged 40 to 49 years without prior PSA screening. Secondary outcomes included anxiety, recall, physician discussion at 3 months, and PSA screening at 3 years. Pictographs versus numeric presentations of genetic risk were also evaluated. RESULTS At 3 months, no significant differences were observed in the rates of PSA screening between the FH arm (2.1%) and the GRS-FH arm (4.5% with GRS-FH vs. 2.1% with FH: χ2 = 3.13, P = .077); however, PSA screening rates at 3 months significantly increased with given risk in the GRS-FH arm (P = .013). Similar results were observed for discussions with physicians at 3 months and PSA screening at 3 years. Average anxiety levels decreased after the individual cancer risk was provided (P = .0007), with no differences between groups. Visual presentation by pictographs did not significantly alter comprehension or anxiety. CONCLUSIONS This is likely the first randomized trial of multimarker genomic testing to report genomic targeting of cancer screening. This study found little evidence of concern about excess anxiety or overuse/underuse of PSA screening when multimarker genetic risks were provided to patients.

Abstract
The relationship between cyclin D1 (CCND1) rs9344 G>A polymorphism and colorectal cancer (CRC) risk is still ambiguous. To obtain a precise estimation of the relationship, we performed an extensive meta-analysis based on the eligible studies. Crude odds ratios with their 95% confidence intervals were harnessed to determine the strength of correlation between CCND1 rs9344 G>A polymorphism and CRC risk under the allele, the homozygote, the dominant, and the recessive genetic models, respectively (28 studies with 5,784 CRC cases and 7,858 controls). Our results indicated evidence of the association between CCND1 rs9344 G>A polymorphism and the increased risk of CRC in four genetic models: A vs G, AA vs GG, AA+GA vs GG, and AA vs GA+GG. In a stratified analysis by cancer type of CRC, there was an increased risk of sporadic CRC found in three genetic models: A vs G, AA vs GG, and AA+GA vs GG. In a stratified analysis by ethnicity, there was an increased CRC risk found among Asians in allele comparison genetic models, as well as Caucasians in two genetic models: AA+GA vs GG and A vs T. In summary, this meta-analysis demonstrates that CCND1 rs9344 G>A polymorphism may be a risk factor for CRC.

The effect of communicating the genetic risk of cardiometabolic disorders on motivation and actual engagement in preventative lifestyle modification and clinical outcome: a systematic review and meta-analysis of randomised controlled trials. Br J Nutr 2016; 116:924-34.

Abstract
Genetic risk prediction of chronic conditions including obesity, diabetes and CVD currently has limited predictive power but its potential to engage healthy behaviour change has been of immense research interest. We aimed to understand whether the latter is indeed true by conducting a systematic review and meta-analysis investigating whether genetic risk communication affects motivation and actual behaviour change towards preventative lifestyle modification. We included all randomised controlled trials (RCT) since 2003 investigating the impact of genetic risk communication on health behaviour to prevent cardiometabolic disease, without restrictions on age, duration of intervention or language. We conducted random-effects meta-analyses for perceived motivation for behaviour change and clinical changes (weight loss) and a narrative analysis for other outcomes. Within the thirteen studies reviewed, five were vignette studies (hypothetical RCT) and seven were clinical RCT. There was no consistent effect of genetic risk on actual motivation for weight loss, perceived motivation for dietary change (control v. genetic risk group standardised mean difference (smd) -0·15; 95 % CI -1·03, 0·73, P=0·74) or actual change in dietary behaviour. Similar results were observed for actual weight loss (control v. high genetic risk SMD 0·29 kg; 95 % CI -0·74, 1·31, P=0·58). This review found no clear or consistent evidence that genetic risk communication alone either raises motivation or translates into actual change in dietary intake or physical activity to reduce the risk of cardiometabolic disorders in adults. Of thirteen studies, eight were at high or unclear risk of bias. Additional larger-scale, high-quality clinical RCT are warranted.

Outreach and Inreach Organized Service Screening Programs for Colorectal Cancer. PLoS One 2016; 11:e0155276.

Abstract
BACKGROUND Outreach (i.e., to invite those who do not use, or who under use screening services) and inreach (i.e., to invite an existing population who have already accessed the medical system) approaches may influence people to increase their use of screening test; however, whether their outcomes would be equivalent remains unclear. METHODS A total of 3,363,896 subjects, 50-69 years of age, participated in a colorectal cancer (CRC) screening program using biennial fecal immunochemical tests; 34.5% participated during 2004-2009 when the outreach approach alone was used, and 65.5% participated from 2010-2013 when outreach was integrated with an inreach approach. We compared the outcomes of the two approaches in delivery of screening services. RESULTS Coverage rates increased from 21.4% to 36.9% and the positivity rate increased from 4.0% to 7.9%, while referral for confirmatory diagnostic examinations declined from 80.0% to 53.3%. The first period detected CRC in 0.20% of subjects screened, with a positive predictive value (PPV) of 6.1%, and the second detected CRC in 0.34% of subjects, with a PPV of 8.0%. After adjusting for confounders, differences were observed in the PPV for CRC (adjusted relative risk, 1.50; 95% confidence interval [CI], 1.41-1.60), cancer detection rate (1.20; 95% CI, 1.13-1.27), and interval cancer rate (0.72; 95% CI, 0.65-0.80). When we focused on the comparison between two approaches during the same study period of 2010-2013, the positivity rate of fecal testing (8.2% vs. 7.6%) and the PPV for CRC detection remained higher (1.07; 95% CI, 1.01-1.12) in subjects who were recruited from the inreach approach. CONCLUSIONS Outcomes of screening were equivalent or better after integration of outreach and inreach approaches. IMPACT The results will encourage makers of health-care policy to adopt the integration approach to deliver screening services.

Abstract
OBJECTIVE To assess the impact of communicating DNA based disease risk estimates on risk-reducing health behaviours and motivation to engage in such behaviours. DESIGN Systematic review with meta-analysis, using Cochrane methods. DATA SOURCES Medline, Embase, PsycINFO, CINAHL, and the Cochrane Central Register of Controlled Trials up to 25 February 2015. Backward and forward citation searches were also conducted. STUDY SELECTION Randomised and quasi-randomised controlled trials involving adults in which one group received personalised DNA based estimates of disease risk for conditions where risk could be reduced by behaviour change. Eligible studies included a measure of risk-reducing behaviour. RESULTS We examined 10,515 abstracts and included 18 studies that reported on seven behavioural outcomes, including smoking cessation (six studies; n=2663), diet (seven studies; n=1784), and physical activity (six studies; n=1704). Meta-analysis revealed no significant effects of communicating DNA based risk estimates on smoking cessation (odds ratio 0.92, 95% confidence interval 0.63 to 1.35, P=0.67), diet (standardised mean difference 0.12, 95% confidence interval -0.00 to 0.24, P=0.05), or physical activity (standardised mean difference -0.03, 95% confidence interval -0.13 to 0.08, P=0.62). There were also no effects on any other behaviours (alcohol use, medication use, sun protection behaviours, and attendance at screening or behavioural support programmes) or on motivation to change behaviour, and no adverse effects, such as depression and anxiety. Subgroup analyses provided no clear evidence that communication of a risk-conferring genotype affected behaviour more than communication of the absence of such a genotype. However, studies were predominantly at high or unclear risk of bias, and evidence was typically of low quality. CONCLUSIONS Expectations that communicating DNA based risk estimates changes behaviour is not supported by existing evidence. These results do not support use of genetic testing or the search for risk-conferring gene variants for common complex diseases on the basis that they motivate risk-reducing behaviour. SYSTEMATIC REVIEW REGISTRATION This is a revised and updated version of a Cochrane review from 2010, adding 11 studies to the seven previously identified.

Abstract
BACKGROUND Increased risk of some comorbidities has been reported in spondyloarthritis (SpA). Recommendations for detection/management of some of these comorbidities have been proposed, and it is known that a gap exists between these and their implementation in practice. OBJECTIVE To evaluate (1) the prevalence of comorbidities and risk factors in different countries worldwide, (2) the gap between available recommendations and daily practice for management of these comorbidities and (3) the prevalence of previously unknown risk factors detected as a result of the present initiative. METHODS Cross-sectional international study with 22 participating countries (from four continents), including 3984 patients with SpA according to the rheumatologist. STATISTICAL ANALYSIS The prevalence of comorbidities (cardiovascular, infection, cancer, osteoporosis and gastrointestinal) and risk factors; percentage of patients optimally monitored for comorbidities according to available recommendations and percentage of patients for whom a risk factor was detected due to this study. RESULTS The most frequent comorbidities were osteoporosis (13%) and gastroduodenal ulcer (11%). The most frequent risk factors were hypertension (34%), smoking (29%) and hypercholesterolaemia (27%). Substantial intercountry variability was observed for screening of comorbidities (eg, for LDL cholesterol measurement: from 8% (Taiwan) to 98% (Germany)). Systematic evaluation (eg, blood pressure (BP), cholesterol) during this study unveiled previously unknown risk factors (eg, elevated BP (14%)), emphasising the suboptimal monitoring of comorbidities. CONCLUSIONS A high prevalence of comorbidities in SpA has been shown. Rigorous application of systematic evaluation of comorbidities may permit earlier detection, which may ultimately result in an improved outcome of patients with SpA.

Abstract
OBJECTIVE To evaluate how personalized quantitative colorectal cancer (CRC) risk information affects laypersons' interest in CRC screening, and to explore factors influencing these effects. METHODS An online pre-post experiment was conducted in which a convenience sample (N=578) of laypersons, aged >50, were provided quantitative personalized estimates of lifetime CRC risk, calculated by the National Cancer Institute Colorectal Cancer Risk Assessment Tool (CCRAT). Self-reported interest in CRC screening was measured immediately before and after CCRAT use; sociodemographic characteristics and prior CRC screening history were also assessed. Multivariable analyses assessed participants' change in interest in screening, and subgroup differences in this change. RESULTS Personalized CRC risk information had no overall effect on CRC screening interest, but significant subgroup differences were observed. Change in screening interest was greater among individuals with recent screening (p=.015), higher model-estimated cancer risk (p=.0002), and lower baseline interest (p<.0001), with individuals at highest baseline interest demonstrating negative (not neutral) change in interest. CONCLUSION Effects of quantitative personalized CRC risk information on laypersons' interest in CRC screening differ among individuals depending on prior screening history, estimated cancer risk, and baseline screening interest. PRACTICE IMPLICATIONS Personalized cancer risk information has personalized effects-increasing and decreasing screening interest in different individuals.

Abstract
PURPOSE Single-nucleotide polymorphism (SNP) panel tests have been proposed for use in the detection of, and prediction of risk for, prostate cancer and as prognostic indicator in affected men. A systematic review was undertaken to address three research questions to evaluate the analytic validity, clinical validity, clinical utility, and prognostic validity of SNP-based panels. METHODS Data sources comprised MEDLINE, Cochrane CENTRAL, Cochrane Database of Systematic Reviews, and EMBASE; these were searched from inception to April 2013. The gray-literature searches included contact with manufacturers. Eligible studies included English-language studies evaluating commercially available SNP panels. Study selection and risk of bias assessment were undertaken by two independent reviewers. RESULTS Twenty-one studies met eligibility criteria. All focused on clinical validity and evaluated 18 individual panels with 2 to 35 SNPs. All had poor discriminative ability (overall area under receiver-operator characteristic curves, 58-74%; incremental gain resulting from inclusion of SNP data, 2.5-11%) for predicting risk of prostate cancer and/or distinguishing between aggressive and asymptomatic/latent disease. The risk of bias of the studies, as assessed by the Newcastle Ottawa Scale (NOS) and Quality Assessment of Diagnostic Accuracy Studies (QUADAS) tools, was moderate. CONCLUSION The evidence on currently available SNP panels is insufficient to assess analytic validity, and at best the panels assessed would add a small and clinically unimportant improvement to factors such as age and family history in risk stratification (clinical validity). No evidence on the clinical utility of current panels is available.Genet Med 18 6, 535-544.

Abstract
The personalized medicine movement-also known as precision medicine and personalized genomics-has embraced the belief that genetic risk information can be used to motivate healthier choices and meaningful behaviour change. While a genuinely exciting area of research, there are numerous policy issues associated with a focus on the use of genetic risk information to personalize approaches to obesity prevention.

Abstract
Encouraging individuals at risk for common complex disease like heart disease, cancer, and diabetes to adopt lifestyle changes (e.g., smoking cessation, exercise, proper nutrition, increased screening) could be powerful public health tools to decrease the enormous personal and economic burden of these conditions. Theoretically, genetic risk information appears to be a compelling tool that could be used to provoke at-risk individuals to adopt these lifestyle changes. Unfortunately, however, numerous studies now have shown that providing individuals with genetic test-based risk information has little to no impact on their behavior. In this article (a commentary not a systematic review), the failed trials in which genetic information has been used as a tool to induce behavior change will be critically examined in order to identify new and potentially more effective ways forward.

Abstract
Little is known about the impact of genetic and environmental risk assessment (GERA) feedback on colorectal cancer (CRC) screening. In a recently completed randomized trial, primary care patients received GERA feedback based on a blood test for genetic polymorphisms and serum folate level (GERA Group) versus usual care (Control Group). Subsequently, participants were offered CRC screening. Among participants who received GERA feedback, being at elevated risk was negatively associated with prospective CRC screening adherence. Secondary analyses of data from this study were performed to identify independent predictors of adherence among participants who received GERA feedback. We obtained baseline survey, follow-up survey, and endpoint medical records data on sociodemographic background, knowledge, psychosocial characteristics, risk status, and adherence for 285 GERA Group participants. Univariate and multivariable analyses were performed to identify predictors of CRC screening adherence. Following a 6-month outcomes observation period, we also conducted two focus groups with GERA Group participants to assess their perceptions of GERA risk feedback and screening. Content analyses of focus group data were evaluated to gain insights into participant response to risk feedback. Overall, half of GERA Group participants adhered to screening within 6 months after randomization. Multivariable analyses showed a statistically significant interaction between race and GERA feedback status relative to screening adherence (p = 0.043). Among participants who received average risk feedback, adherence was comparable among whites (49.7 %) and nonwhites (54.1 %); however, among those at elevated risk, adherence was substantially higher among whites (66.7 %) compared to nonwhites (33.3 %). Focus group findings suggest that whites were more likely than nonwhites to view elevated risk feedback as a prompt to screen. In response to receiving elevated risk feedback, nonwhites were more likely than whites to report feeling anxiety about the likelihood of being diagnosed with CRC. Further research is needed to explore race-related CRC screening differences in response to GERA feedback.
