Abstract
First-degree relatives of patients with colorectal cancer (CRC) are at high risk of this disease. For this reason, medical organizations and clinical guidelines recommend more intensive screening and surveillance for such first-degree relatives than for the average-risk population. Colonoscopy has been the cornerstone of CRC screening in this setting. Although colonoscopy is the most sensitive technique for the detection of neoplastic lesions (especially non-advanced adenomas), its role is less clear for CRC. In addition, screening colonoscopy has several limitations that may affect the success of a screening campaign, such as poor participant acceptance, the need for skilled endoscopists, participant access to screening colonoscopy, overburdened endoscopy units, potential complications, and procedure-related costs. In addition, recent evidence has cast doubt on the advantage of colonoscopy over other strategies for the detection of advanced neoplastic lesions. Despite being less sensitive in general, other screening methods frequently recommended in the average-risk population may be more acceptable and thus help increase CRC screening uptake. This review discusses recent evidence on the risk of CRC in first-degree relatives, the advantages and disadvantages of each screening technique, participation rates depending on the technique, patient preferences, and barriers to screening.

Abstract
AIM The aims of the present study were: (i) to evaluate the focal incidental colorectal uptake of (18)F-fluorodeoxyglucose ([(18)F]FDG) and to correlate it with colonoscopy and histological findings; (ii) to evaluate the relationship between the presence/absence of neoplastic disease and clinical data and the anatomical site of [(18)F]FDG uptake; and (iii) to compare our results with those reported for incidental colorectal uptake of [(18)F]FDG in the literature and those obtained from various screening programmes for colorectal cancer. METHOD The database of 6000 patients referred for [(18)F]FDG positron emission tomography/computed tomography (PET-CT) to our centre was retrospectively reviewed for incidental colorectal uptake of [(18)F]FDG. Patients with focal uptake were selected and the aetiology of PET findings was verified with a subsequent colonoscopy and histopathological analysis when available. RESULTS Incidental colorectal uptake of [(18)F]FDG was seen in 144 (2.4%) patients, of whom 64 (1.1%) had focal uptake; 48 out of these 64 patients underwent colonoscopy, which showed malignant tumours in 12 (25%), premalignant lesions in 19 (40%), non-neoplastic lesions in six (12%) and lesions not confirmed by colonoscopy in 11 (23%). Our data agreed with previously published data. Statistical analysis did not show any significant relationship between the presence/absence of neoplastic disease and patient sex or age, type of primary disease and anatomical site of [(18)F]FDG uptake. Comparing our data with various screening programmes, a significant difference was found only with series in which colonoscopy was performed in patients at high risk for colorectal cancer. CONCLUSION Focal incidental colorectal uptake of [(18)F]FDG is observed in about 1% of PET/CT studies and carries a high risk of neoplastic disease. A PET-CT report should suggest colonoscopy when abnormal findings are reported.

Abstract
OBJECTIVE Colonoscopy is empirically recommended as the first choice screening strategy in first-degree relatives of patients with colorectal cancer (CRC). However, this strategy is accepted by less than 40% of the risk population and two-thirds of screened individuals and renders a normal exploration. This pilot study assessed the accuracy of a latex agglutination immunochemical fecal occult blood test (LA-FOBT) for detecting advanced colorectal neoplasm (cancer or adenomatous polyps > or =1 cm in size, with villous pattern or high grade dysplasia) in asymptomatic first-degree relatives of patients with CRC. METHODS One hundred and sixty-nine first-degree relatives of 135 index cases were prospectively included. All participants received a sensitive LA-FOBT (hemoglobin detection limit of 50 ng/ml buffer), and were invited to undergo colonoscopy. On the whole, 116 (69%) participants returned LA-FOBT and underwent colonoscopy. RESULTS LA-FOBT was positive in 19 of 116 (16%) cases. Colonoscopy detected neoplasms in 49 of 116 (42%) patients: 37 of 116 (32%) were nonadvanced adenomas and 12 of 116 (10%) advanced adenomas. LA-FOBT detected 10 of 12 (83%) advanced adenomas showing a sensitivity, specificity, positive predictive value, and negative predictive value of 83, 91, 53, and 98%, respectively. In patients with positive LA-FOBT, 1.9 colonoscopies were necessary for detecting one advanced adenoma, whereas in case of not performing this test 10 colonoscopies would be needed. Overall, approximately 80% of screening colonoscopies could be precluded using a LA-FOBT. CONCLUSION One-time screening with LA-FOBT successfully detects advanced colorectal adenomas and may save unnecessary colonoscopies in first-degree relatives of patients with CRC.

Abstract
INTRODUCTION Barriers to targeted colonoscopic screening of first-degree relatives of colorectal cancer patients have been the subject of considerable literature, always as seen from the patient's viewpoint. In the specific context of screening individuals with a family history, physicians may also play a predominant role in motivating their colorectal cancer patients to pass on screening information to their relatives. The aim of this study was to examine the views of general practitioners and specialists regarding barriers and facilitators affecting participation of relatives in colonoscopic screening. METHODS A qualitative study was conducted to collect and analyse information from two focus groups of 4 general practitioners and 9 gastroenterologists respectively, and from semi-structured individual interviews with 10 general practitioners, 2 surgeons and 3 oncologists. An extended focus group of 36 gastroenterologists was organized to validate the results. RESULTS The main barriers to colonoscopic screening of FDRs were associated with lack of direct communication between physicians and FDRs. Physicians needed support in the task of informing index patients and persuading them to transfer information on screening to their FDRs. The general practitioners spoke of their expectations in terms of training in and motivation for promoting screening and the gastroenterologists expressed the wish for patient education material specific to colonoscopy and for systematic post-colonoscopy consultations to inform patients about their results, follow-up and screening their relatives. CONCLUSION The findings, notably the need for specific education materials and for training to improve the motivation of physicians, will help to develop effective interventions intended to increase participation in screening.

Abstract
Literature regarding screening behaviour in individuals with a family history of colorectal cancer was reviewed, in order to determine the prevalence of screening in this population and identify factors associated with screening participation. Four electronic databases were searched from 1994. Thirty papers met the inclusion criteria, including 3 community surveys, 13 studies on first-degree relatives of colorectal cancer patients, and 14 studies on genetic services for colorectal cancer risk assessment. Individuals with a family history of colorectal cancer, who have not received risk assessment, frequently have never had any form of screening for colorectal cancer. Uptake of endoscopic screening when offered to individuals identified as being at increased risk was generally high (often >60% participation). Having a medical recommendation to screen, a stronger family history and perceiving fewer barriers to screening were identified as predictors of screening behaviour. Existing data suggest that use of screening tests in individuals with a family history of colorectal cancer is variable, and our understanding of factors associated with screening behaviour is limited. A number of methodological problems in research to date were identified, and further research is needed in order to inform interventions to support sustained screening participation in this population.

Abstract
AIMS To characterize determining factors for compliance with colonoscopy recommendations in the familial screening of colorectal cancer through exploration of individual psychosociological factors and issues relating to patient/physician/sibling communication. METHODS A qualitative approach involving a review of the literature and interviews with general practitioners, specialists, patients, and their siblings. RESULTS A confrontation of the content of interviews with data from the literature made it possible to confirm the relevance of classic prevention models, the Health Belief Model and the Theory of Planned Behavior in the French cultural and healthcare environments, as well as their ability to identify the main individual factors liable to motivate or to discourage familial screening. The family network plays a decisive part in the transmission of information from the patient towards siblings. Physicians have expectations relating to communication aids and backup. This study above all highlights the difficulty in determining who is best suited to giving information to the patient, and when and how to relay this information to first-degree relatives. CONCLUSION In view of the many difficulties in establishing interaction between patient, physician and siblings that is liable to lead on to efficient screening, we propose the study of the usefulness of a health-counseling intervention aimed to tailor and follow-up the delivery of screening information to the first-degree relatives.

Abstract
BACKGROUND Current guidelines recommend screening colonoscopy in first-degree relatives of patients with colon cancer. The aim of this state-wide study was to investigate the compliance for colonoscopic in first-degree relatives, who were younger than 60 years of age. METHODS A total of 602 patients were identified from the tumor registry of the public health insurance of Lower Saxony. A questionnaire was sent to these patients, which included a number of different questions regarding their knowledge about the risk of colon cancer for their family members, as well as their participation in screening colonoscopy. RESULTS Data from 442 patients and their first-degree relatives (1005 siblings and 354 parents) were available; 178 parents had undergone screening colonoscopy and 344 siblings. Interestingly, the percentage of siblings who underwent screening colonoscopy was significantly higher (27%) among those siblings where the index patients were aware of the increased risk for the first-degree relatives, in contrast to the siblings of the index patients who were not aware of this risk (20%). CONCLUSION This study demonstrates that only a minority of first-degree relatives undergo screening colonoscopy and that informing patients about the potential risk for their relatives will increase participation in screening colonoscopy in first-degree relatives of the patients.

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 Little is known about compliance with colonoscopy as a screening method in first-degree relatives of patients with large adenomas. Aims To evaluate the compliance with screening colonoscopy among this population, and its determinants. METHODS Data were obtained from the family part of the GEADE study, a study on genetic factors of colorectal adenomas. Index cases were 306 patients with adenomas > or = 10 mm. All living first-degree relatives aged 40-75 who could be contacted by the index case were asked to undergo a colonoscopy, unless they had had one in the previous 5 years. RESULTS Among 674 eligible relatives, 56 had had a colonoscopy within the preceding 5 years and 114 underwent a screening colonoscopy resulting in a compliance with screening colonoscopy of 18%. This was not related to most characteristics of index cases. Compliance was significantly lower when the index case lived in the Greater Paris area than when he/she lived in other areas (12% vs. 21%). It was higher in siblings (18%) and offspring (23%) than in parents (9%) and in relatives under 55 years old (22%) than in relatives aged 55 and over (15%). CONCLUSIONS Compliance with colonoscopy was low in first-degree relatives of patients with large adenomas. The reasons for this should be determined and appropriate strategies developed to increase compliance.

Abstract
OBJECTIVE Direct and indirect evidence supports the concept of screening for adenomas and early stage colorectal cancer in reducing the incidence and disease-specific mortality. Controversy remains as to the appropriateness of and preferred methods for screening an asymptomatic population. METHODS Review of computed tomography (CT) colonography based on the literature and personal experience. RESULTS AND CONCLUSIONS Current discrepancies in the data on accuracy and patient acceptance of CT colonography reflect differences in the performance and evaluation of this examination. Before CT colonography can be implemented in colorectal cancer screening, factors that cause this variability must be elucidated. Studies in which high-resolution scanning, three-dimensional review methods and an enhanced colonoscopic reference are used achieve an accuracy that is similar to colonoscopy. At the same time the evidence that ultra-low radiation dose CT colonography is feasible is mounting, a development that dramatically reduces one of the largest obstacles for large-scale application of this technique.
