RESUMO

The question of returning to work and pursuing professional activity during cancer treatment is an increasingly important consideration. The present work focuses on factors affecting the feasibility of maintaining professional activity during treatment for breast cancer, for women who wished to do so. Written questionnaires were collected from 216 patients between March and November 2012. Since the onset of their treatment, 31.4% of the women (68/216) had not been on sick-leave. The main factors associated with the pursuit of professional activity were: considering the availability of their physician to answer questions as unimportant [OR = 18.83 (3.60-98.53); P ≤ 0.05]; considering the diagnosis of cancer as likely to have a weak impact on career perspectives [OR = 4.07 (2.49-6.64); P ≤ 0.05]; not having any children in the household [OR = 3.87 (2.38-6.28); P ≤ 0.05]; being in a managerial position [OR = 3.13 (1.88-5.21); P ≤ 0.05]. Negative predictive factors were: physician mentioning adverse effects of the treatment [OR = 0.31 (0.16-0.58); P ≤ 0.05], and patient rating workload as high [OR = 0.26 (0.15-0.46); P ≤ 0.05]. As a result of advances in therapeutic strategies, more patients will expect healthcare professionals, as well as employers and occupational health societies, to prioritise issues pertaining to the maintenance of professional activities during cancer treatment.

RESUMO

PURPOSE: Our previously published data showed rapidly increasing rates of prostate cancer screening in men aged 50-74, which rose from 36% in 2005 to 48% in 2008. Based on men's reported intentions at that time, this was expected to rise to 70% in 2011. Here we report the actual rate of prostate cancer screening. METHOD: Three nationwide observational telephone surveys (EDIFICE opinion polls) were conducted in 2005, 2008, and 2011. The overall target was a representative sample of > 1,500 individuals living in France and aged 40-75 years, including 481 men aged 50-74 years. RESULTS: Within this male population, the rate of screening reported remained stable between 2008 and 2011 (48 and 49%, respectively). However, comparison of privileged versus disadvantaged populations showed significant differences, with a relative decrease in screening among those of higher socioprofessional status (p = 0.03) and from higher-income groups (p = 0.02). For households with a monthly income above 2,500€, the screening rate decreased from 61% in 2008 to 51% in 2011 (p = 0.05), while for those with an income below 2,500€, it increased from 36% in 2008 to 44 % in 2011 (p = 0.18). CONCLUSION: A plateau or even a reduction in prostate cancer screening is currently being observed; this is possibly due to progressive recognition among the population at large of the controversy surrounding prostate cancer screening, whereas this speculation was formerly limited to health-care professionals. After previously being more likely to undergo prostate cancer screening, it is the younger, wealthier populations that are currently showing the most noteworthy step backwards.

RESUMO

OBJECTIVES: The incidence of skin cancers, melanoma in particular, is increasing rapidly. Consequently, specific recommendations for sun-protection measures now exist. This survey set out to assess the compliance of the general population with these guidelines. METHODS: The French nationwide observational survey, EDIFICE Melanoma, was conducted (28 September to 20 October 2011) through phone interviews of a representative sample of 1502 subjects aged ≥ 18 years, using the quota method. Sun-protection was defined as frequent or systematic use of clothes or sunscreen. The group of individuals who declared exposure to the sun (N = 1172) was subdivided: risk-takers (N = 442), and those who used sun protection (N = 730). RESULTS: Risk-takers were significantly more often male (62% vs. 44%, P < 0.01), had a lower level of education (40% vs. 26%, P < 0.01), lower incomes (2587 euros vs. 2948 euros/month) and were more often smokers (42% vs. 31%, P < 0.01). In contrast, age, marital status and use of sunbeds were not significantly different between the two groups. Interestingly, risk-takers had less risk factors for melanoma. However, they were less well-informed about high-risk exposure and optimal use of sunscreen. Sun-protection measures for their children were less stringent than those of the group who used sun protection: systematic/frequent use of sunglasses (42% vs. 59%, P < 0.01), systematic use of sunscreen (77% vs. 86%, P < 0.01), and frequent renewal (69% vs. 82%, P < 0.01), high sun protection factors (SPF) (46% vs. 56%, P < 0.01), use of clothing (84% vs. 92%, P < 0.01) and hats (88% vs. 94%, P < 0.01). CONCLUSIONS: Risk-takers are characterized by a lesser understanding of sun-protection measures and behaviours. Their children benefit less from protective measures than those of people who use sun protection themselves. Improved understanding may well improve behaviours; one can therefore legitimately predict a considerable impact on parents' attitude to their own protection and that of their children.

RESUMO

BACKGROUND/AIM: Sociodemographic factors associated with colorectal cancer screening participation have been extensively analysed although few, if any, studies have focused on regional/geographical factors as determinants of non-participation rates. The purpose of this study was to investigate the effects of individual and geographical determinants on the variable participation rates seen for colorectal cancer screening. METHODS: The study population comprised 183,978 individuals in the first round of screening and 175,596 in the second round, all of whom were residents of the city of Marseille in France. The influence of age, gender and regional/geographical characteristics, such as proportion of migrants and property prices per square meter, on participation rates was assessed by multilevel analysis. RESULTS: The participation rate was lower for men (0.85; 95% CI: 0.83-0.86), and higher for those aged 65-69 years. Univariate analysis showed that participation rates were significantly different across the 16 municipal districts of Marseille (range: 22.8-36.7%; OR: 1.97; 95% CI: 1.86-2.08). On multivariate analysis, having a higher proportion of migrants in the district population was still associated with lower participation (OR: 0.96; 95% CI: 0.95-0.97). CONCLUSION: In addition to individual factors, regional/geographical factors appear to be relevant determinants of participation rates in urban colorectal cancer screening programs.

RESUMO

OBJECTIVE: BRCA1/2 gene mutations are not frequently identified in breast or ovarian cancer patients who are the first members of their family to be tested. Little is known about how probands interpret and cope with these results, which are generally referred to as 'inconclusive'. The aim of this study was to describe subjective understanding by women with cancer in response to an inconclusive BRCA1/2 test, describing the difficulties or non-difficulties they encountered about the transmission of information to their family. METHODS: A cohort of 30 women with breast/ovarian cancer were followed for a period of up to 2 years after delivery of their inconclusive genetic test results. Self-administered questionnaires with closed and open questions were distributed. A qualitative analysis of open-ended questions is presented here. RESULTS: These women's reactions to inconclusive results were of three kinds. The majority (n=14) were still uncertain about their carrier status, which is an adequate medical interpretation of the results, while others (n=9) took their inconclusive results to mean that they were definitely not carriers, and the women in the last group (n=7) were convinced that they were actually carriers. There was some overlap between these perceptions and actual genetic risk. CONCLUSIONS: The transmission of information to the family was found to differ qualitatively across the three groups and more difficulties in this respect were expressed by those who were uncertain about their carrier status.

RESUMO

BACKGROUND: The EDIFICE survey aimed to investigate the compliance of the general population to the screening tests available in France for the 4 most common cancers: breast, colorectal, prostate and lung. Implementation of breast cancer screening has been generalized in France since 2003: women aged between 50 and 74 years are systematically invited to perform a mammography every second year. Results pertaining to breast cancer are reported hereafter. METHODS: This nationwide observational survey was carried out in France from 18 January to 2 February 2005 among representative samples of 773 women aged between 40 and 75 years and 600 general practitioners (GPs). Information collected included socio-demographic characteristics, attitude towards cancer screening and actual experience of cancer screening, as well as GPs' practice regarding screening. The precision of the results is +/- 4.3% for a 95% confidence interval. RESULTS: Among the 507 participating women aged between 50 and 74 years, 92.5% (469/507) had undergone at least one mammography: 54.6% (256/469) underwent this test on their own initiative and 44.6% (209/469) of women performed it in the framework of a systematic screening plan. Most women participating in the systematic screening (89.0% i.e. 186/209) had a mammography within the last dating from less than 2 years versus 73.8% (189/256) of those who performed it outside the screening program (Chi(2) test; p<0.01). Interestingly, 422 women (61.9% i.e. 422/682 women aged between 40-75 years with at least one mammography) had performed a mammography before the recommended age for screening. There was a significant correlation (p = 0.009) between the existence of a first mammography before 50 years of age and subsequent screening on women's own initiative (54.6% of 469 screened women). Main reasons for not performing the screening test every second year (77 women aged between 50-74 years) included: feeling unconcerned and/or unmotivated (p = 0.0001), no cancer anxiety (p = 0.020) and no recommendation by the GP (p = 0.015); Of the 600 participating GPs, 68.6% (412/600) systematically recommended a mammography to their patients. GPs' perceptions of the reasons for women's avoidance of the screening test were unwillingness to be aware of mammography results (44.4% - 266/600) and the belief that mammography was painful (52.5% - 315/600). CONCLUSION: The main result of the EDIFICE survey is the high rate of women's attendance at mammography screening. The EDIFICE survey pointed out that systematic and organized screening played a major role in the regularity of screening tests for breast cancer every second year. GPs and gynaecologist are key actors in heightening public awareness.

RESUMO

The Hereditary Non-Polyposis Colorectal Cancer syndrome (HNPCC) has initially been described as a predisposition to colorectal cancers (CRC). Subsequently, other cancers, such as endometrial cancers (EC), have been added. The objective of this review was to update data on endometrial cancers of HNPCC syndrome. Endometrial cancers of the HNPCC syndrome are characterized by a younger age at diagnosis (46-48 year old), and a higher cumulative risk along life (30% at 70 years). Complex atypical hyperplasia seems to occur before the cancer, but the transition between precursors and cancer seems to be short. Histology of endometrial cancers of the HNPCC syndrome appears quite similar to that of sporadic cases, except for non-endometrioid lesions which seem more frequent and could occur in younger women. Screening of endometrial cancer in predisposed women should associate annual clinical examination, transvaginal sonography and endometrial sampling. Unfortunately, available data on screening by sonography show that this test seems poorly accurate, with no asymptomatic cancer or hyperplasia recognized and interval cancers between screenings. Endometrial biopsy appears as the most interesting method, since 11 asymptomatic cancers and 14 hyperplasia have been diagnosed in 175 mutation carriers. Diagnostic hysteroscopy seems also interesting, but requires further evaluation. Prophylactic hysterectomy confers a complete protection against endometrial cancer. However, perioperative morbidity (especially in women with history of colorectal surgery) and long-term effects of ovarian suppression should also be considered. Screening of endometrial cancer remains the main objective of the management of those patients. Endometrial biopsy should have a larger place.

RESUMO

The existence of two subgroups of BRCA1-associated breast cancer (BC) families has been recently posited: the first with highly proliferating tumors, and the second composed of cases with a low proliferation rate. Our aim was to test whether the proliferation rate of BRCA1-associated breast cancers was affected by the site of the germ line mutation in the BRCA1 gene. We analyzed the distribution of the mitotic index, a histoprognostic grade component shown to segregate in families, matching for germ line mutation location in a series of 28 breast cancers from 20 kindreds. We observed a prevalence of highly proliferating tumors when the mutation occurs in the two terminal conserved domains of the BRCA1 protein, ie., in the amino and carboxyl termini (P = 0.0024). Our data provide evidence for a genotype-phenotype correlation and along with their strong conservation during evolution argue for the importance of these two regions in the control of mammary cell growth.

RESUMO

A family history of breast and/or ovarian cancer is the main criterion used in screening BRCA1 gene carriers. However, ascertaining a patient's family history is a difficult task, which significantly restricts the use of this parameter in clinical practice. Alternative individual criteria that can be used to identity BRCA1 gene carriers would, therefore, be of great value. In this context, it was recently established that BRCA1-associated breast cancers (BRCA1-BCs) show a specific morphoclinical pattern. In multivariate analyses, the two most discriminant morphoclinical parameters available for establishing the BRCA1 status, in addition to an early age at onset, are estrogen receptor negativity (ER-) and poor tumor differentiation (TD3). Here we tested the efficacy of these two morphological parameters as BRCA1 mutation indicators and investigated their economic impact, in a population-based survey on a series of women who developed invasive breast cancer by the age of 35 years, regardless of their family history. A high rate of 28.6% of BRCA1 mutations was found to have occurred in the group of tumors with both ER- and TD3 versus only 3.6% in tumors with other profiles (P = 0.007; odds ratio, 10.8). When the sole criterion used was early onset by the age of 35 years, the mutation rate was found to be 8.6%. The resulting cost of testing only women with ER- and TD3 tumors worked out at 30% that of testing the whole population of women with cancer by the age of 35 years, and the sensitivity was found to be of 66%. Lastly, the family history of ER- and TD3 cases with a BRCA1 mutation was investigated retrospectively, and none of these cases was found to have a particularly extensive family history of breast and/or ovarian cancer. The use of these morphological features of BRCA1-BCs that are currently typed in clinical practice, therefore, provides a helpful and cost-effective tool for those making decisions about genetic screening. This strategy makes it possible to identify gene carriers who would be overlooked using current criteria.

RESUMO

Deletions of genomic regions involving tumor suppressor genes are thought to be important in the initiation and progression of breast cancer. We conducted a genome-wide search for deleted regions in a series of 75 human breast carcinomas by studying the allelic patterns of 184 microsatellite markers distributed over all chromosomes and looking for loss of heterozygosity (LOH). We identified 56 regions of consistent LOH. Strikingly, every tumor had a different set of deletions. To study this complexity, we applied a phylogenetic-like type of analysis. Each region was involved in a certain proportion of tumors, ranging from 20 to 62%; the most frequently involved regions were on chromosome arms 8p, 11q, 16q, and 17p. There was a correlation (P = 0.005) between the level of LOH and the size of the tumors. Tumors with a high level of LOH were also highly proliferative and had a high mitotic index.

RESUMO

Histoprognostic grade is a determinant parameter to select the initial therapeutic strategy in breast cancer. Our aim was to analyze the grade repartition in BRCA1-associated breast cancer (BC) and to explore the possible connections between grade and the BRCA1 gene function. We first compared 27 BRCA1-associated BCs from 14 families with 4,461 cases from an administrative district registry and 242 cases from a hospital-based registry, matching for grade and constitutive elements, and then considered their repartition in families. We observed a prevalence of grade 3 (P < 0.0001) in BRCA1-associated BC. This was attributed mainly to nuclear polymorphism (P < 0.0001), mitotic activity (P < 0.0001), and tubular differentiation (P = 0.0004), implying that BRCA1-associated BCs are highly proliferating tumors. Moreover, it is suggested that grade segregates as a genetic trait within families (P = 0.0015), and this was attributed to the mitotic index segregation only (P = 0.0005). Therefore grade, through its components, could be interpreted as the morphological translation of the BRCA1 germ line mutation. Thus, a genotype-phenotype correlation may exist between the type of mutation and the aggressiveness of the disease. These findings are bound to have an important impact in the care management of hereditary breast cancer at the individual and at the familial level and in the comprehensive approach of breast cancer development.

RESUMO

BRCA1-associated breast cancers (BRCA1-BCs) frequently harbor a high histoprognostic grade, p53 alterations, and estrogen receptor negativity. Although these parameters predict a poor outlook, the overall survival in BRCA1-BCs is equivalent to or even better than that in sporadic cases. These features are reminiscent of what is observed for breast carcinoma of the medullary type, a high-grade tumor with a particular favorable course. To explore a possible relationship between this phenotype and BRCA1 mutations, we first compared 32 BRCA1-BCs and 200 consecutive cases of breast cancer without familial history for the prevalence of typical medullary breast carcinoma (TMC) using the criteria given by Ridolfi et al. [R. Ridolfi et al, Cancer (Phila.), 40: 1365-1385, 1977]. Second, we searched for BRCA1 mutations in a set of 18 cases of TMC, using denaturing gradient gel electrophoresis and Cleavase fragment length polymorphism scanning. Six of 32 (19%) BRCA1-BCs were of the TMC type, compared to 0 of 200 controls (P < 0.0001). Among the 18 TMCs, 2 BRCA1 nonsense mutations were found. This corresponds to almost 7 times the contribution of BRCA1 mutations in the general population. Two additional missense mutations were identified. Together, these results suggest that, although TMC and BRCA1-BCs are not strictly coincidental, an important connection between the two populations does exist.

RESUMO

Breast cancer carrying BRCA mutation may be highly sensitive to DNA-damaging agents. We hypothesized a better outcome for BRCA-mutated (BRCA(mut)) metastatic breast cancer (MBC) patients receiving high-dose chemotherapy and autologous hematopoietic stem cell transplantation (HDC AHSCT) versus unaffected BRCA (BRCA wild type; (BRCA(wt))) or patients without documented BRCA mutation (BRCA untested (BRCA(ut))). All female patients treated for MBC with AHSCT at Institut Paoli-Calmettes between 2003 and 2012 were included. BRCA(mut) and BRCA(wt) patients were identified from our institutional genetic database. Overall survival (OS) was the primary end point. A total of 235 patients were included. In all, 15 patients were BRCA(mut), 62 BRCA(wt) and 149 BRCA(ut). In multivariate analyses, the BRCA(mut) status was an independent prognostic factor for OS (hazard ratio (HR): 3.08, 95% confidence interval (CI): 1.10-8.64, P=0.0326) and PFS (HR: 2.52, 95% CI :1.29-4.91, P=0.0069). In this large series of MBC receiving HDC AHSCT, we report a highly favorable survival outcome in the subset of patients with documented germline BRCA mutations.

RESUMO

PURPOSE: Familial aggregation among patients with several hematological malignancies has been revealed. This emphasizes the importance of genetic factors. Only few genes predisposing to familial hematological malignancies have been reported until now due to the low occurrence. We have described in previous study PRF1 and CEBPA variants that might contribute to the background of genetic factors, which encourage us to extend our investigations to other cooperating genes. The aim of this study is to determine whether germline additional sex combs-like 1 (ASXL1) gene mutations may be involved? METHODS/PATIENTS: In this study, we investigated the candidate gene ASXL1 by direct sequencing in 88 unrelated Tunisian and French families with aggregated hematological malignancies. RESULTS: We report a new p.Arg402Gln germline missense substitution in two related Tunisian patients which has not been previously described. We identified here this variant for the first time in non-Hodgkin lymphoma. The p.Arg402Gln variant was not found in 200 control chromosomes. In silico analysis has predicted potential deleterious effect on ASXL1 protein. CONCLUSIONS: From an extended candidate genes analyzed in the field of familial hematological malignancies, ASXL1 might be involved. This variant should be considered since a potential damaging effect was predicted by in silico analysis, with a view to develop functional assay in order to investigate the biological assessment.

RESUMO

We have analysed losses of heterozygosity (LOH) at eight markers from the p12-p22 region of human chromosome 8 in a panel of 113 breast tumors. LOH were detected in almost half of the tumors. The most frequently deleted region included microsatellite (CA)n repeats markers D8S258, D8S133 and D8S259, located at 8p12-p22, while markers NEFL and LPL appeared less frequently altered. In parallel, linkage analysis was performed using the same informative markers, to test for the involvement of chromosome 8p loci in familial breast cancer. Positive cumulative multipoint lod score of 2.51 at theta = 0.0 was obtained with markers NEFL and D8S259. These results suggest that region 8p12-p22 carries at least one tumor suppressor gene involved in sporadic and perhaps also in familial breast cancer.

RESUMO

To appreciate the involvement of known or potential susceptibility genes in sporadic breast tumors, we have searched for chromosomal deletions by studying loss of heterozygosity (LOH) at 43 microsatellite (CA)n markers from human chromosomes 10, 11 and 17, in 115 unselected consecutive samples of breast carcinoma with particular emphasis on specific regions. No site of consistent LOH was identified on chromosome 10. Five regions of LOH were contained within bands q22-24 of chromosome 11 for which nearly 50% of the tumors had LOH at at least one marker. This region is thus a major site of deletion in breast cancer and several tumor suppressor genes seem to be involved. One of them may be the ataxia telangiectasia (ATM) gene which is located in one of the affected regions. Five regions of LOH, one of which is within the BRCA1 gene area, were recognized along chromosome 17. LOH at three of these regions were found in highly proliferative tumors. When combined with a previous study of chromosome 13 with emphasis on BRCA2 and Rb1 genes, this work allowed to distinguish a total of 12 regions of LOH, variably affected in breast tumors and correlated with prognostic parameters.

RESUMO

BACKGROUND: The hereditary non-polyposis colon cancer (HNPCC) syndrome is an inherited condition defined by clinical and genealogical information, known as Amsterdam criteria. In about 70% of cases, HNPCC syndrome is caused by germline mutations in MMR genes, leading to microsatellite instability of tumor DNA (MSI phenotype). Patients affected by the disease are at high risk for colorectal and endometrial carcinomas, but also for other organs tumors. HNPCC syndrome is responsible for 5% of colorectal cancers. MAJOR ASPECTS: The lack of sensitivity of Amsterdam criteria in recognizing patients carrying a MMR germline mutation led to an enlargement of these criteria for the recruitment of possible HNPCC patients, and to a two-steps strategy, asking first for a tumor characterization according to MSI phenotype, especially in case of early-onset sporadic cases. FURTHER DEVELOPMENTS: The identification of germline MMR mutations has no major consequence on the cancer treatments, but influences markedly the long-term follow-up and the management of at-risk relatives. Gene carriers will enter a follow-up program regarding their colorectal and endometrial cancer risks; other organs being at low lifetime risk, no specific surveillance will be proposed.

RESUMO

After a BRCA mutation has been identified in the context of hereditary breast/ovarian cancer (HBOC), mammographic screening and prophylactic surgery are two of the main options available to those responsible for the clinical management of healthy women. The aim of this study was to describe the attitudes of specialists towards the clinical management of women with an HBOC risk: this information was collected prior to the publication of the recent French guidelines. A random national sample of 1169 French surgeons, gynaecologists and obstetricians was surveyed using a mailed questionnaire, to which 700 of these physicians (60%) responded. When dealing with a BRCA mutated woman, 88.6% of the respondents said they would recommend mammographic screening, but only 27.1% would recommend that it should be carried out annually from the age of 30 years onwards, as recommended in the French guidelines; 10.9% would find it acceptable to propose prophylactic mastectomy from the age of 30 years, and 22.9% would find it acceptable to propose prophylactic oophorectomy from the age of 35 years. The specialists who agreed with recommending breast/ovarian cancer genetic testing also had more positive attitudes towards prophylactic mastectomy (adj OR = 3.4, 95% CI = 1.4-8.2), as did those who had previously recommended prophylactic mastectomy when gene testing was not yet available (adj OR = 2.06, 95% CI = 1.23-3.44). The respondents' attitudes towards prophylactic oophorectomy and mastectomy were significantly associated (adj OR = 3.9; 95% CI = 2.3-6.5). Previous recommendation of prophylactic mastectomy was associated (P < 0.01) with a higher level of knowledge of breast/ovarian cancer genetics and with medical practice in this field. French physicians' attitudes towards mammographic screening and prophylactic surgery were not in complete agreement with the subsequently published French guidelines, the impact of which has now to be considered. Constantly evolving knowledge about the efficacy of preventive intervention will give practitioners new elements to integrate into their counselling.

RESUMO

Cancer patients attend oncogenetic clinics so that the existence of a genetic risk can be checked and the relatives informed. The aim of this study was to describe the expectations of cancer patients about genetic counselling and their beliefs about the aetiology of their disease. A survey based on self-administered questionnaires before and after the consultation was carried out on 115 women with breast/ovarian cancer who attended one of the six French participating clinics. In 59 cases (51%), the consultees' expectations focused on the preventive options available and in 86 cases (75%) on their offspring; 87 (76%) found the consultation informative. On average, the women rated heredity and diet as lower risk factors (P < 0.05) after the consultation than before. Heredity, stress and the environment were thought to be more decisive than diet, smoking and alcohol. 34 patients who seemed unlikely to have a genetic risk in the consultant's opinion thought heredity to be less relevant (P < 0.05) after the consultation than before. At the time of the survey, cancer patients accounted for at least half of the consultees attending oncogenetic clinics in France. They need to have the clinical specificities of their disease and its medical management explained. They attend mainly for their offspring's sake, whereas healthy clients attend for their own sake.

RESUMO

The aim of this study was to determine in healthy consultees attending cancer genetics clinics their risk status, their pathways leading to the clinics, their expectations and perception of cancer risk. In 1994, the consultees at six French centres completed a questionnaire before their first oncogenetic consultation. The oncogeneticists subsequently filled in a standardised form giving their risk assessment. Among the 206 healthy consultees, 91.3% were women, 92.2% had at least one cancer-affected first-degree relative and 73% had a "cancer family risk" as assessed by the oncogeneticist. Sixty-nine per cent of the consultees were referred to the clinics by a physician, 10.4% by their family and 18.8% on their own initiative: 83.5% of the sample perceived their family risk of cancer as being high and this belief was confirmed in 74.3% of the cases studied by the oncogeneticist. The families of self-referred consultees were less often at risk than those of consultees referred by a physician or by their family (P = 0.012). The majority (78%) expected to be informed about cancer prevention and screening, and this expectation depended on the consultee's level of education (P = 0.001). This study shows that medical pathways are more effective than the media as a means of reaching the members of the general population who are genuinely at risk, and shows that fuller information about prevention needs to be provided at cancer genetic consultations.
