Although multigene panel testing (MGPT) is increasingly utilized in clinical practice, there remain limited data on patient-reported outcomes. BRCA 1/2 negative patients were contacted and offered MGPT. Patients completed pre- and posttest counseling, and surveys assessing cognitive, affective and behavioral outcomes at baseline, postdisclosure and 6 and 12 months. Of 317 eligible BRCA1/2 negative patients who discussed the study with research staff, 249 (79%) enrolled. Decliners were more likely to be older, non-White, and recruited by mail or email. Ninety-five percent of enrolled patients proceeded with MGPT. There were no significant changes in anxiety, depression, cancer specific distress or uncertainty postdisclosure. There were significant but small increases in knowledge, cancer-specific distress and depression at 6-12 months. Uncertainty declined over time. Those with a VUS had significant decreases in uncertainty but also small increases in cancer specific distress at 6 and 12 months. Among those with a positive result, medical management recommendations changed in 26% of cases and 2.6% of all tested. Most BRCA1/2 negative patients have favorable psychosocial outcomes after receipt of MGPT results, although small increases in depression and cancer-specific worry may exist and may vary by result. Medical management changed in few patients. 相似文献

We investigated the uptake of genetic testing by 54 families in South East Scotland with a BRCA1/2 mutation. At a median of 37 months since identification of the mutation, the overall rate of uptake of testing in 269 eligible family members was 32%. First-degree relatives were significantly (P<0.05) less likely to be referred for genetic counselling in more, compared to less, socioeconomically deprived families (46 versus 68%). Among relatives who attended for genetic counselling, females were more likely to be tested than males (76 versus 53%; P<0.05) and relatives with children more than those without children (82 versus 53%; P<0.001). Tested relatives were older than relatives who did not undergo testing (mean 41.9 versus 36.8 years, P<0.05) but did not differ in degree of relationship to the index case or in socioeconomic deprivation. Our results confirm the findings from other studies of substantially lower rates of uptake of genetic testing for BRCA1/2 mutations than anticipated in earlier predictions. Relatives in more socioeconomically deprived families were less likely to be referred for genetic counselling, which is a matter of concern. This may be partly the result of a lack of understanding of the testing process. Cascading currently does not work in breast cancer families and further work is required to investigate intrafamilial communication patterns, testing behaviour and counselling strategies. 相似文献

Pristauz G, Petru E, Stacher E, Geigl J B, Schwarzbraun T, Tsybrovskyy O, Winter R & Moinfar F(2010) Histopathology 57, 877–884 Androgen receptor expression in breast cancer patients tested for BRCA1 and BRCA2 mutations Aim: To assess the expression of receptors for androgen (AR), oestrogen (ER) and progesterone (PR) as well as human epidermal growth factor receptor type 2 (Her‐2/neu) status of breast carcinomas in breast cancer susceptibility gene (BRCA) BRCA1/2 mutation carriers and BRCA1/2 negative tested women. Methods: One hundred and thirty‐five breast cancers in women tested for BRCA1/2 mutations. Screening for BRCA1 and BRCA2 mutations was performed by direct sequencing of all BRCA1 and BRCA2 exons as well as the surrounding intronic sequences. Additionally, BRCA genes were analysed with multiplex ligation‐dependent probe amplification. Consecutive paraffin sections were examined immunhistochemically for AR, ER, PR and Her‐2/neu. Results: Of the 135 tumours, 43 (32%) were BRCA1‐related, 18 (13%) were BRCA2‐related and 74 (55%) were BRCA1/2‐negative. Seventy‐two per cent of the BRCA1‐related, 22% of the BRCA2‐related and 12% of the BRCA1/2‐negative tumours were triple (ER, PR, Her2neu)‐negative. Eighty‐four per cent of BRCA1 mutated cancers were high‐grade (G3) tumours. ARs were expressed in 30% (13 of 43) of BRCA1‐related, in 78% (14 of 18) in BRCA2‐related tumours and in 76% (56 of 74) in BRCA1/2 negative tumours. Twenty‐one per cent of ER‐negative BRCA1‐related tumours expressed androgen receptors. Conclusion: Approximately one in five BRCA1 mutated breast cancers negative for ER and PR express androgen receptors. Modulation of AR might open a new avenue for treating these high‐risk cancers. 相似文献

Several studies have reported that women with ovarian cancer and a BRCA1 or BRCA2 mutations have better survival than women with ovarian cancer and no mutation. Potential reasons for this include possible differences in histologic subtype, stage, grade and response to chemotherapy, but some of the difference in survival may be due to systematic bias, i.e. a difference in survival rates for women who do and who do not undergo genetic testing. We estimated the survival rate in 1423 ovarian cancer patients from Ontario who had genetic testing and compared this with the survival rate for all 3367 ovarian cancer patients from the province from whom the tested sample was derived. Tested women had a 10‐year survival of 54.5%, compared to 35.8% for all patients in the province. We evaluated the extent to which three different methods of adjustment eliminated the observed difference. The adjusted rates for the tested cohort were closer to the provincial average, but each adjustment method resulted in a modest over‐estimate of 10‐year survival, ranging from 6.1% to 10.0%. The mortality advantage for tested women was due, in part, to a lower than expected mortality rate of tested women in the period following genetic testing. 相似文献

Accurate estimates of breast and ovarian cancer penetrance in BRCA1/2 mutation carriers are crucial in genetic counseling. Estimation is difficult because of the low frequency of mutated alleles and the often-uncertain mechanisms of family ascertainment. We estimated the penetrances of breast and ovarian cancers in carriers of BRCA1/2 mutations by maximizing the retrospective likelihood of the genetic model, given the observed test results, in 568 Italian families screened for germline mutations. The software BRCAPRO was used as a probability calculation tool in a Markov Chain Monte Carlo approach. Breast cancer penetrances were 27% (95% CI 20-34%) at age 50 years and 39% (27-52%) at age 70 in BRCA1 carriers, and 26% (0.18-0.34%) at age 50 and 44% (29-58%) at age 70 in BRCA2 carriers, and ovarian cancer penetrances were 14% (7-22%) at age 50 and 43% (21-66%) at age 70 in BRCA1 carriers and 3% (0-7%) at age 50 and 15% (4-26%) at age 70 in BRCA2 carriers. The new model gave a better fit than the current default in BRCAPRO, the likelihood being 70 log units greater; in addition, the observed numbers of mutations in families stratified by gene and by cancer profile were not significantly different from those expected. Our new penetrance functions are appropriate for predicting breast cancer risk, and for determining the probability of carrying BRCA1/2 mutations, in people who are presently referred to genetic counseling in Italy. Our approach could lead to country-customized versions of the BRCAPRO software by providing appropriate population-specific estimates. 相似文献

Many rearrangement mutations in the BRCA1 gene have been identified. It is becoming clear that some of these mutations are prevalent, and therefore their detection is necessary in order for clinical genetic tests to have high sensitivity. Published information on particular rearrangements is frequently limited to a single patient, small groups of patients, or patients of a particular ethnicity. The objectives of this work included characterizing the prevalence of five specific rearrangement mutations in a large North American patient population. A mutation-specific multiplex PCR assay was used for determining the prevalence of five BRCA1 rearrangement mutations that previously had been reported to occur in unrelated patients. The mutation status of these rearrangements, which came from 20,712 patients at high risk for hereditary breast and/or ovarian cancers who had submitted specimens for clinical genetic testing, is presented. The results, obtained from 2,634 mutation carriers, showed a 6-kb duplication of exon 13, identified in 53 patients (2.01%); a 26-kb deletion encompassing exons 14-20, detected in seven patients (0.27%); a 510-bp deletion of exon 22, detected in 5 patients (0.19%); and a 3.4-kb deletion of exon 13, detected in one patient (0.04%). A previously reported 7.1-kb deletion of exons 8-9 was not found. The high frequency of the exon 13 duplication makes it the fourth most prevalent mutation in these patients. These results provide an accurate picture of the prevalence of these mutations in hereditary breast/ovarian cancer patients undergoing genetic testing in North America. 相似文献

Hereditary breast cancer comprises a minor but clinically meaningful breast cancer (BC) subgroup. Mutations in the major BC‐susceptibility genes are important prognostic and predictive markers; however, their carriers represent only 25% of high‐risk BC patients. To further characterize variants influencing BC risk, we performed SOLiD sequencing of 581 genes in 325 BC patients (negatively tested in previous BRCA1/BRCA2/PALB2 analyses). In 105 (32%) patients, we identified and confirmed 127 truncating variants (89 unique; nonsense, frameshift indels, and splice site), 19 patients harbored more than one truncation. Forty‐six (36 unique) truncating variants in 25 DNA repair genes were found in 41 (12%) patients, including 16 variants in the Fanconi anemia (FA) genes. The most frequent variant in FA genes was c.1096_1099dupATTA in FANCL that also show a borderline association with increased BC risk in subsequent analysis of enlarged groups of BC patients and controls. Another 81 (53 unique) truncating variants were identified in 48 non‐DNA repair genes in 74 patients (23%) including 16 patients carrying variants in genes coding proteins of estrogen metabolism/signaling. Our results highlight the importance of mutations in the FA genes' family, and indicate that estrogen metabolism genes may reveal a novel candidate genetic component for BC susceptibility. 相似文献

Heterozygous carriers of ATM (ataxia telangiectasia mutated gene) mutations have increased risk of breast cancer (BC). We have estimated the prevalence of mutations in the ATM gene among Spanish patients with early-onset BC. Forty-three patients diagnosed with BC before the age of 46 years, and negative for BRCA1 and BRCA2 mutations, were analysed for the presence of ATM mutations. A total of 34 ATM sequence variants were detected: 1 deleterious mutation, 10 unclassified variants and 23 polymorphisms. One patient (2.3%) carried the ATM deleterious mutation (3802delG that causes ataxia telangiectasia in the homozygous state) and 13 patients carried the 10 ATM unclassified variants. The truncating mutation 3802delG and eight of the rare variants were not detected in a control group of 150 individuals. Different bioinformatic sequence analysis tools were used to evaluate the effects of the unclassified ATM changes on RNA splicing and function protein. This in silico analysis predicted that the missense variants 7653 T>C and 8156 G>A could alter the splicing by disrupting an exonic splicing enhancer motif and the 3763 T>G, 6314 G>C, and 8156 G>A variants would affect the ATM protein function. These are the initial results concerning the prevalence of germline mutations in the ATM gene among BC cases in a Spanish population, and they suggest that ATM mutations can confer increased susceptibility to early-onset BC. 相似文献

The perceived benefits and risks of genetic testing may vary between groups of individuals with different cultural, demographic, and family history features. This multicentre study examined the factors that influenced the decision to undergo genetic testing for BRCA1 and BRCA2 in Canadian Jewish women with breast cancer. A self-administered questionnaire was developed and distributed to 134 individuals enrolled in a research-based testing program for Ashkenazi women. The questionnaire assessed demographic, social, and family history parameters, and the influence of medical, family, social, psychological, and cultural/religious factors on decision making about genetic testing. Seventy-six percent of women completed the questionnaire. Forty-one percent of study participants had no family history of breast or ovarian cancer. The most important factors influencing the decision to undergo testing were a desire to contribute to research, potential benefit to other family members, curiosity, and the potential for relief if not found to be a carrier (endorsed by 87, 78, 70, and 60% of participants, respectively). The main perceived risks of undergoing genetic testing related to insurance discrimination, confidentiality, accuracy and interpretability of results, potential impact on marriage prospects for family members, and focus on the Jewish community (endorsed by 28, 24, 30, 17, and 14% of participants, respectively). This study provides novel information on the motivating factors for BRCA1 and BRCA2 mutation testing in Canadian women of Ashkenazi Jewish descent. The focus on altruistic factors and those related to perceived psychological benefits of testing is notable. 相似文献

OBJECTIVE: Ovarian cancer is the leading cause of gynecological death in the United States, and 14% of ovarian cancer cases are attributed to BRCA1/2 hereditary mutations. This study examined (1) change in subjective ovarian cancer risk in response to genetic counseling and testing, (2) accuracy of subjective ovarian cancer risk estimates, and (3) new methods for conceptualizing subjective ovarian cancer risk based on Leventhal's Common Sense Model, in women at increased risk to carry BRCA1/2 mutations. METHODS: Women (n=78) were asked their subjective risk of ovarian cancer (in terms of a percentage, estimated survival time, and projected age of onset) at pre-counseling, post-counseling, 1 week post-result, and 6 months post-result. RESULTS: Women with a personal history of breast cancer were most inaccurate at pre- but improved post-counseling. Subjective survival time increased post-counseling. Accuracy of subjective risk improved at post-result for those with uninformative negative results. Subjective percentage risk and subjective survival time decreased at 6 months. CONCLUSIONS: Subjective risk changed in response to genetic counseling and testing. Common Sense Model-derived assessments of risk may be useful for understanding the impact of genetic counseling and testing. PRACTICE IMPLICATIONS: Genetic counseling can assist women at risk of carrying BRCA1/2 mutations to understand their risk of ovarian cancer, and genetic testing further refines their risk. 相似文献

232 family members from 27 Norwegian families with BRCA1 mutations were offered genetic testing. 180/232 (78%) chose to be tested, 14/232 (6%) have not yet decided and 38/232 (16%) declined. All 232 persons were invited to fill in the following questionnaires when offered testing: Impact of Event Scale (IES), Hospital Anxiety and Depression Scale (HADS), General Health Questionnaire (GHQ-28) and Beck Hopelessness Scale (BHS). 207/232 (89%) responded to the questionnaires. Of those declining to be tested 23/38 (61%) answered the questionnaires compared to 170/180 (94%) of those wanting the test (p < 0.0001). A higher proportion of females with a history of cancer than females without such a history had abnormal scores on the IES-intrusion and GHQ questionnaires (p < 0.001). Healthy females who were deciding on predictive testing had the same or lower prevalence of mental distress compared to the general population, between 4.3% and 18.0% as measured by the different questionnaires. Males did not differ from healthy females on any of the measures. According to their HADS scores, women without a history of cancer deciding on predictive testing for breast-ovarian cancer had lower or equal levels of mental distress compared to the general population. The high uptake of genetic testing combined with the lower than normal prevalence of mental distress indicates that the activity may continue as practised, awaiting longitudinal data concerning the levels of mental distress after genetic testing. 相似文献

There have been few studies addressing uptake of predictive testing for BRCA1/2 , only one comparing a proactive with usual family networking approach to dissemination. We report uptake of predictive genetic testing after directly offering BRCA1 presymptomatic genetic testing to 100 individuals in two generations of 5 large BRCA1 families compared with service testing of 196 families since that time. Uptake was significantly higher in the first generation (group 1), who were directly offered testing, and much higher in females. Seventy-four percent of unaffected women in the first generation proceeded to testing, 42% of men. This decreased to 44% of women in the second generation (group 2) and 9% males (p = 0.0003). Uptake in unaffected individuals in the final group (group 3) with no proactive approach was significantly lower than that in the first group. Overall uptake after 10 years was 56% (95% confidence interval, CI, 50–62%) for group 1 and 36% (95% CI 34.3–37.7%) for 1084 group 3 individuals (p = 0.0003). Among women, uptake was 74% (95% CI 67–81%) in group 1 at 10 years compared with 51.5% (95% CI 49–54%) in 552 group 3 women (p = 0.023). In men, uptake was 42% (95% CI 33–52%) in group 1 and 21.1% (95% CI 18.1–23.1%) among 532 men in group 3 (p = 0.0098). Although these results are not from a randomized trial, they show particularly among men a substantially higher uptake of genetic services with a direct approach. Importance should be given to more proactive approaches to ensure that men in BRCA1/2 -positive families receive the appropriate information. 相似文献

Familial aggregation is thought to account for 5-10% of all breast cancer cases, and high penetrance breast and ovarian cancer susceptibility genes BRCA1 and BRCA2 explain < or =20% of these. Hundreds of mutations among breast/ovarian cancer families have been found in these two genes. The mutation spectrum and prevalence, however, varies widely among populations. Thirty-six breast/ovarian cancer families were identified from a population sample of breast and ovarian cancer cases among a relatively isolated population in Eastern Finland, and the frequency of BRCA1/BRCA2 germline mutations were screened using heteroduplex analysis, protein truncation test and sequencing. Five different mutations were detected in seven families (19.4%). Two mutations were found in BRCA1 and three in BRCA2. One of the mutations (BRCA2 4088insA) has not been detected elsewhere in Finland while the other four, 4216-2nt A-->G and 5370 C-->T in BRCA1 and 999del5 and 6503delTT in BRCA2, are recurrent Finnish founder mutations. These results add to the evidence of the geographical differences in distribution of Finnish BRCA1/BRCA2 mutations. This screen also provides further evidence for the presumption that the majority of Finnish BRCA1/BRCA2 founder mutations have been found and that the proportion of BRCA1/BRCA2 mutations in Finnish breast/ovarian cancer families is around 20%. 相似文献

PurposePopulation screening for BRCA1/BRCA2. mutations is being considered for Ashkenazi Jews (AJ) because 2.5% carry recurrent deleterious mutations and effective cancer prevention exists. This study aimed to provide a qualitative focus on perspectives of individuals, particularly carriers, who were tested through a screening trial. In this trial, the pretest process included only written information.MethodsInterviews were performed with 26 carriers and 10 noncarriers who participated in a BRCA population screening trial for AJ.ResultsAttitudes toward screening were generally positive. The main motivator for testing was knowledge of BRCA status to enable cancer risk reduction. Knowledge of carrier status, although challenging, was thus viewed as health-empowering. The screening paradigm was sensed as increasing awareness and as overcoming access, referral, and familial barriers. Streamlining the pretest process was positively perceived as offering gradual, stepwise knowledge commensurate with test results. Participants were concerned that health systems provide the necessary conceptual and infrastructural framework and that individual autonomy be maintained.ConclusionsBRCA screening in AJ is viewed favorably, even by carriers. Stepwise acquisition of knowledge based on test results was viewed as most relevant to the screening context. Screening program development should account for safeguarding autonomy and providing requisite post-test services.Genet Med advance online publication 01 December 2016 相似文献

PurposeThe purpose of this study was to analyze laboratory performance on proficiency testing surveys offered jointly by the College of American Pathologists/American College of Medical Genetics and Genomics biannually for the three common Ashkenazi Jewish founder mutations in the BRCA1 and BRCA2 genes.MethodsSurvey responses were analyzed for accuracy of genotype determination and the associated clinical interpretation. Data on an individual laboratory’s participation over time, number of samples tested, turnaround time, and test methodology were also reviewed.ResultsBetween 2003 and 2012, 23 US laboratories and 39 international laboratories participated. There were six genotyping errors, with a corresponding analytical sensitivity of 99.0% (479/484 challenges; 95% confidence interval: 97.6–99.7%) and an analytic specificity of 99.9% (870/871; 95% confidence interval: 99.4–99.9%). Among the 1,325 clinical interpretations, 92.5% (1,226/1,325; 95% confidence interval: 91.0–93.9%) matched the intended response. Most of the 99 discrepancies—81% (80/99)—incorrectly interpreted the risk for a negative test result as having a lifetime risk of breast cancer “that is the same as that in the general population” instead of “that cannot be determined without BRCA mutation testing of the affected relative.”ConclusionClinical laboratories demonstrated excellent analytical sensitivity and specificity. The clinical interpretation requires additional education, focusing on the clinical interpretation of negative test results for these three mutations.ConclusionGenet Med advance online publication 19 June 2014 相似文献

Three founder alleles of BRCA1 (C61G, 4153delA, 5382insC) were reported in Poland in 2000, and these three mutations have comprised the standard testing panel used throughout the country. However, since 2000, other recurrent mutations of BRCA1 and BRCA2 have been reported. To establish if the inclusion of one or more of these mutations will increase the sensitivity of the standard test panel, we studied 1164 Polish women with unselected breast cancer diagnosed at age of 50 or below. All women were genotyped for 12 recurrent mutations of BRCA1 and BRCA2. We identified a mutation in 83 of 1164 patients (7.1%) including 61 women with one of the original three mutations (C61G, 4153delA, 5382insC) and 22 women with a different mutation (1.9%). Three new mutations (3819del5, 185delAG and 5370C>T) were seen in multiple families. By including these three mutations in the extended panel, the mutant frequency increased from 5.2 to 6.7%. Polish women with breast cancer diagnosed at age of 50 or below should be screened with a panel of six founder mutations of BRCA1 (C61G, 4153delA, 5382insC, 3819del5, 185delAG and 5370C>T). 相似文献

PurposeTo determine when, in reference to the course of their treatment, women with ovarian cancer are seen for genetic counseling, as well as to determine what factors influence this timing.MethodsSingle institution retrospective chart review of patients with ovarian cancer who underwent BRCA1/BRCA2 genetic testing.ResultsThirty-three percent of our sample (n = 100) were seen for genetic counseling after ovarian cancer recurrence. In four cases, genetic test results were disclosed to next of kin. Thirty percent of women seen for genetic counseling after recurrence received their initial treatment elsewhere. Women with a history of breast cancer were significantly more likely to be seen for genetic counseling at an earlier phase of their treatment than women with no history of breast cancer.ConclusionWe found that one third of patients with ovarian cancer who underwent genetic testing were seen for initial genetic counseling after disease recurrence. In some cases, genetic counseling took place during the end of life care, with genetic test results disclosed to next of kin. Given the poor prognosis of women with recurrent ovarian cancer, we advocate providing genetic counseling at the time of initial ovarian cancer treatment both in comprehensive cancer centers and in community oncology settings. 相似文献

PurposePopulation screening of three common BRCA1/BRCA2 mutations in Ashkenazi Jews (AJ) apparently fulfills screening criteria. We compared streamlined BRCA screening via self-referral with proactive recruitment in medical settings.MethodsUnaffected AJ, age ≥25 years without known familial mutations, were either self-referred or recruiter-enrolled. Before testing, participants received written information and self-reported family history (FH). After testing, both non-carriers with significant FH and carriers received in-person genetic counseling. Psychosocial questionnaires were self-administered 1 week and 6 months after enrollment.ResultsOf 1,771 participants, 58% were recruiter-enrolled and 42% were self-referred. Screening uptake was 67%. Recruited enrollees were older (mean age 54 vs. 48, P < 0.001) and had less suggestive FH (23 vs. 33%, P < 0.001). Of 32 (1.8%) carriers identified, 40% had no significant FH. Post-test counseling compliance was 100% for carriers and 89% for non-carrier women with FH. All groups expressed high satisfaction (>90%). At 6 months, carriers had significantly increased distress and anxiety, greater knowledge, and similar satisfaction; 90% of participants would recommend general AJ BRCA screening.ConclusionStreamlined BRCA screening results in high uptake, very high satisfaction, and no excess psychosocial harm. Proactive recruitment captured older women less selected for FH. Further research is necessary to target younger women and assess other populations.Genet Med advance online publication 08 December 2016 相似文献
