Odhiambo P, Okello H, Wakaanya A, Wekesa C, Okoth P. Mutational signatures for breast cancer diagnosis using artificial intelligence. J Egypt Natl Canc Inst 2023; 35:14. [PMID: 37184779 DOI: 10.1186/s43046-023-00173-4] [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: 07/02/2022] [Accepted: 04/19/2023] [Indexed: 05/16/2023] Open
Abstract
BACKGROUND Breast cancer is the most common female cancer worldwide. Its diagnosis and prognosis remain scanty, imprecise, and poorly documented. Previous studies have indicated that some genetic mutational signatures are suspected to lead to progression of various breast cancer scenarios. There is paucity of data on the role of AI tools in delineating breast cancer mutational signatures. This study sought to investigate the relationship between breast cancer genetic mutational profiles using artificial intelligence models with a view to developing an accurate prognostic prediction based on breast cancer genetic signatures. Prior research on breast cancer has been based on symptoms, origin, and tumor size. It has not been investigated whether diagnosis of breast cancer can be made utilizing AI platforms like Cytoscape, Phenolyzer, and Geneshot with potential for better prognostic power. This is the first ever attempt for a combinatorial approach to breast cancer diagnosis using different AI platforms. METHOD Artificial intelligence (AI) are mathematical algorithms that simulate human cognitive abilities and solve difficult healthcare issues such as complicated biological abnormalities like those experienced in breast cancer scenarios. The current models aimed to predict outcomes and prognosis by correlating imaging phenotypes with genetic mutations, tumor profiles, and hormone receptor status and development of imaging biomarkers that combine tumor and patient-specific features. Geneshotsav 2021, Cytoscape 3.9.1, and Phenolyzer Nature Methods, 12:841-843 (2015) tools, were used to mine breast cancer-associated mutational signatures and provided useful alternative computational tools for discerning pathways and enriched networks of genes of similarity with the overall goal of providing a systematic view of the variety of mutational processes that lead to breast cancer development. The development of novel-tailored pharmaceuticals, as well as the distribution of prospective treatment alternatives, would be aided by the collection of massive datasets and the use of such tools as diagnostic markers. RESULTS Specific DNA-maintenance defects, endogenous or environmental exposures, and cancer genomic signatures are connected. The PubMed database (Geneshot) search for the keywords yielded a total of 21,921 genes associated with breast cancer. Then, based on their propensity to result in gene mutations, the genes were screened using the Phenolyzer software. These platforms lend credence to the fact that breast cancer diagnosis using Cytoscape 3.9.1, Phenolyzer, and Geneshot 2021 reveals high profile of the following mutational signatures: BRCA1, BRCA2, TP53, CHEK2, PTEN, CDH1, BRIP1, RAD51C, CASP3, CREBBP, and SMAD3.

Breast Cancer Res Treat 2019; 177:705-711. [PMID: 31280425 PMCID: PMC6745275 DOI: 10.1007/s10549-019-05338-1] [Citation(s) in RCA: 17] [Impact Index Per Article: 3.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/20/2019] [Accepted: 06/26/2019] [Indexed: 12/25/2022]
Abstract
PURPOSE To investigate the utility of mammography for breast cancer screening in a population of males at increased risk for breast cancer. METHODS In this HIPAA-compliant institutional review board-approved single-institution study, mammography records and clinical data of 827 male patients who underwent digital mammography from September 2011-July 2018 were analyzed via the electronic medical record. 664 of these men presented with masses, pain, or nipple discharge and were excluded from this study. The remaining 163 asymptomatic men with familial and/or personal history of breast cancer, or with a known germline mutation in BRCA, underwent screening mammography and were included in this analysis. RESULTS 163 asymptomatic men (age: mean 63 years, range 24-87 years) underwent 806 screening mammograms. 125/163 (77%) had a personal history of breast cancer and 72/163 (44%) had a family history of breast cancer. 24/163 (15%) were known mutation carriers: 4/24 (17%) BRCA1 and 20/24 (83%) BRCA2. 792/806 (98%) of the screening mammograms were negative (BI-RADS 1 or 2); 10/806 (1.2%) were classified as BI-RADS 3, all of which were eventually downgraded to BI-RADS 2 on follow-up. 4/806 (0.4%) mammograms were abnormal (BI-RADS 4/5): all were malignant. The cancer detection rate in this cohort was 4.9 cancers/1000 examinations. CONCLUSIONS In our cohort, screening mammography yielded a cancer detection rate of 4.9 cancers/1000 examinations which is like the detection rate of screening mammography in a population of women at average risk, indicating that screening mammography is of value in male patients at high risk for breast cancer.

Abstract
The concept 'hereditary breast cancer' is commonly used to delineate a group of people genetically at risk for breast cancer-all of whom also having risk for other cancers. People carrying pathogenic variants of the BRCA1 and BRCA2 genes are often referred to as those having predisposition for 'hereditary breast cancer'. The two genes, however, are when altered, associated with different risks for and dying from breast cancer. The main risk for dying for carriers of both genes is from ovarian cancer. These biological facts are of philosophical interest, because they are the facts underlying the public debate on BRCA1/2 genetic testing as a model for the discussion of how to implement genetic knowledge and technologies in personalized medicine. A contribution to this public debate describing inherited breast cancer as 'biological citizenship' recently printed in Med Health Care and Philos illustrated how fragmented and detached from the biological and socio-political facts this debate sometimes is. We here briefly summarize some of the biological facts and how they are implemented in today's healthcare based on agreed philosophical, ethical and moral principles. The suggestion of a 'biological citizenship' defined by hereditary breast cancer is incorrect and ill-advised. 'Identity politics' focusing hereditary breast cancer patients as a group based on a bundle of ill-defined negative arguments is well known, but is supported neither by scientific nor philosophical arguments. To those born with the genetic variants described, the philosophical rule of not doing harm is violated by unbalanced negative arguments.

Abstract
Background The genetic mechanisms for families who meet the clinical criteria for Lynch syndrome (LS) but do not carry pathogenic variants in the mismatch repair (MMR) genes are still undetermined. We aimed to study the potential contribution of genes other than MMR genes to the biological and clinical characteristics of Norwegian families fulfilling Amsterdam (AMS) criteria or revised Bethesda guidelines. Methods The Hereditary Cancer Biobank of the Norwegian Radium Hospital was interrogated to identify individuals with a high risk of developing colorectal cancer (CRC) for whom no pathogenic variants in MMR genes had been found in routine diagnostic DNA sequencing. Forty-four cancer susceptibility genes were selected and analyzed by using our in-house designed TruSeq amplicon-based assay for targeted sequencing. RNA splicing- and protein-dedicated in silico analyses were performed for all variants of unknown significance (VUS). Variants predicted as likely to affect splicing were experimentally analyzed by resorting to minigene assays. Results We identified a patient who met the revised Bethesda guidelines and carried a likely pathogenic variant in CHEK2 (c.470 T > C, p.I157T). In addition, 25 unique VUS were identified in 18 individuals, of which 2 exonic variants (MAP3K1 c.764A > G and NOTCH3 c.5854G >A) were analyzed in the minigene splicing assay and found not to have an effect on RNA splicing. Conclusions Among high-risk CRC patients that fulfill the AMS criteria or revised Bethesda guidelines, targeted gene sequencing identified likely pathogenic variant and VUS in other genes than the MMR genes (CHEK2, NOTCH3 and MAP3K1). Our study suggests that the analysis of genes currently excluded from routine molecular diagnostic screens may confer cancer susceptibility.

Genetic variants of prospectively demonstrated phenocopies in BRCA1/2 kindreds. Hered Cancer Clin Pract 2018; 16:4.

Abstract
Background In kindreds carrying path_BRCA1/2 variants, some women in these families will develop cancer despite testing negative for the family’s pathogenic variant. These families may have additional genetic variants, which not only may increase the susceptibility of the families’ path_BRCA1/2, but also be capable of causing cancer in the absence of the path_BRCA1/2 variants. We aimed to identify novel genetic variants in prospectively detected breast cancer (BC) or gynecological cancer cases tested negative for their families’ pathogenic BRCA1/2 variant (path_BRCA1 or path_BRCA2). Methods Women with BC or gynecological cancer who had tested negative for path_BRCA1 or path_BRCA2 variants were included. Forty-four cancer susceptibility genes were screened for genetic variation through a targeted amplicon-based sequencing assay. Protein- and RNA splicing-dedicated in silico analyses were performed for all variants of unknown significance (VUS). Variants predicted as the ones most likely affecting pre-mRNA splicing were experimentally analyzed in a minigene assay. Results We identified 48 women who were tested negative for their family’s path_BRCA1 (n = 13) or path_BRCA2 (n = 35) variants. Pathogenic variants in the ATM, BRCA2, MSH6 and MUTYH genes were found in 10% (5/48) of the cases, of whom 15% (2/13) were from path_BRCA1 and 9% (3/35) from path_BRCA2 families. Out of the 26 unique VUS, 3 (12%) were predicted to affect RNA splicing (APC c.721G > A, MAP3K1 c.764A > G and MSH2 c.815C > T). However, by using a minigene, assay we here show that APC c.721G > A does not cause a splicing defect, similarly to what has been recently reported for the MAP3K1 c.764A > G. The MSH2 c.815C > T was previously described as causing partial exon skipping and it was identified in this work together with the path_BRCA2 c.9382C > T (p.R3128X). Conclusion All women in breast or breast/ovarian cancer kindreds would benefit from being offered genetic testing irrespective of which causative genetic variants have been demonstrated in their relatives.

Abstract
Background BRCA2 c.68-7T>A has been demonstrated to cause aberrant splicing and is possibly pathogenic. The population prevalence of the variant is 0.2%, which higher than usual for pathogenic BRCA2 variants. The pathogenicity of the variant is discussed. Methods The outpatient genetic clinic at The Norwegian Radium Hospital, part of Oslo University Hospital, has invited breast cancer kindreds for genetic examinations and prospective follow-up of high risk patients since 1988. We have complete files of all activities and results, and we examined the files for association between BRCA2 c.68-7T>A and breast cancer. Results Seventeen out of 714 (2.4%) breast cancer kindreds sequenced for BRCA2 carried the variant BRCA2 c.68-7T>A (p < 0.0001 compared to population controls). Segregation analysis was inconclusive (likelihood ratio 0.36) for pathogenicity. Two breast cancers were prospectively observed during 134 observation years (annual incidence rate 1.5% (95% CI 0.15% to 5.4%) and one additional breast cancer was diagnosed at first (prevalence) round. Conclusion BRCA2 c.68-7T>A is associated with breast cancer. In the families selected due to aggregation of breast cancer, carriers of the BRCA2 c.68-7T>A variant have increased risk for breast cancer. It is, however, possible that the variant has lower penetrance than the average pathogenic BRCA2 variants, and that in the families selected for having known aggregation of breast cancer other (modifying) factors contributed to the observed results.

Abstract
Background The addition of annual MRI screening to mammography has heightened optimism that intensive screening along with improved treatments may substantially improve life expectancy of women at high risk of breast cancer. However, survival data from BRCA2 mutation carriers undergoing intensive combined breast screening are scarce. Methods We have collated the results of screening with either annual mammography or mammography with MRI in female BRCA2 mutation carriers in Manchester and Oslo and use a Manchester control group of BRCA2 mutation carriers who had their first breast cancer diagnosed without intensive screening. Results Eighty-seven BRCA2 mutation carriers had undergone combined (n = 34) or mammography (n = 53) screening compared to 274 without such intensive screening. Ten year breast cancer specific survival was 100 % in the combined group (95 % CI 82.5–100 %) and 85.5 % (95 % CI 72.6–98.4 %) in the mammography group compared to 74.6 % (95 % CI 66.6–82.6 %) in the control group. Better survival was driven by lymph node status (negative in 67 % of screened vs 39 % of unscreened women; p < 0.001) and a significantly greater proportion of intensively screened women had invasive breast cancers <2 cm at diagnosis (74.6 % vs 50.4 %; p = 0.002). Conclusion Intensive combined breast cancer screening with annual MRI and mammography appears to improve survival from breast cancer in BRCA2 mutation carriers. Data from larger groups are required to confirm the effectiveness of combined screening in BRCA2 carriers.

Abstract
Women from breast cancer families without a demonstrable BRCA1/2 mutation were subjected to annual mammography from age 30 years onwards. One-hundred and ninety-eight patients were diagnosed prospectively with invasive breast cancer and followed for a total of 1513 years. Overall 10-year survival was 88 %. Together with our previous report that women in such kindreds had about twice the population risk of breast cancer, the combined conclusion was that the overall chances of developing breast cancer causing death within 10 years before 50 years of age was 1 % or less when subjected to annual mammography and current treatment. These are empirical prospective observations which may be used for genetic counselling. The majority (160/194 = 84 %) of patients had ER+ and/or low grade tumours with 92 % 10-year survival. One minor group of the patients had ER- tumours, another small group had high grade tumours with nodal spread, both groups were associated with worse prognosis, but the two groups were not mutually associated.

Effectiveness of Screening With Annual Magnetic Resonance Imaging and Mammography: Results of the Initial Screen From the Ontario High Risk Breast Screening Program. J Clin Oncol 2014; 32:2224-30. [DOI: 10.1200/jco.2013.52.8331] [Citation(s) in RCA: 90] [Impact Index Per Article: 9.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 11/20/2022] Open
Abstract
Purpose The Ontario Breast Screening Program expanded in July 2011 to screen women age 30 to 69 years at high risk for breast cancer with annual magnetic resonance imaging (MRI) and digital mammography. To the best of our knowledge, this is the first organized screening program for women at high risk for breast cancer. Patients and Methods Performance measures after assessment were compared with screening results for 2,207 women with initial screening examinations. The following criteria were used to determine eligibility: known mutation in BRCA1, BRCA2, or other gene predisposing to a markedly increased risk of breast cancer, untested first-degree relative of a gene mutation carrier, family history consistent with hereditary breast cancer syndrome and estimated personal lifetime breast cancer risk ≥ 25%, or radiation therapy to the chest (before age 30 years and at least 8 years previously). Results The recall rate was significantly higher among women who had abnormal MRI alone (15.1%; 95% CI, 13.8% to 16.4%) compared with mammogram alone (6.4%; 95% CI, 5.5% to 7.3%). Of the 35 breast cancers detected (16.3 per 1,000; 95% CI, 11.2 to 22.2), none were detected by mammogram alone, 23 (65.7%) were detected by MRI alone (10.7 per 1,000; 95% CI, 6.7 to 15.8), and 25 (71%) were detected among women who were known gene mutation carriers (30.8 per 1,000, 95% CI, 19.4 to 43.7). The positive predictive value was highest for detection based on mammogram and MRI (12.4%; 95% CI, 7.3% to 19.3%). Conclusion Screening with annual MRI combined with mammography has the potential to be effectively implemented into an organized breast screening program for women at high risk for breast cancer. This could be considered an important management option for known BRCA gene mutation carriers.

Abstract
PURPOSE The purpose of this article is to highlight some new findings from a qualitative study that have not been previously considered. METHOD The research was based on a qualitative phenomenological method. Data were collected by semi-structured individual interviews. A purposeful sample was recruited from West Norway of 14 women with a possible risk of developing breast and ovarian cancer. Data collection took place at least one year after prophylactic removal of the ovaries. Data from the study was analyzed according to the phenomenological method of Amedeo Giorgi. KEY FINDINGS Two themes were revealed as essential factors of the interviewed women's experiences: "the loss of a mother" and "dealing with genetic cancer risk." For the most part, these two themes also appeared to be interrelated. When a mother died of ovarian cancer while her daughter was a child or a young woman, this often led to her daughter's strong desire to find an explanation for her mother's death, as well as to her efforts to undergo genetic testing and surgery to prevent cancer in her family in the future. CONCLUSION The study indicates that women's experiences in families at risk of hereditary cancer are closely related to an understanding of their life stories, particularly their "loss of a mother," and how this influences how they deal with genetic cancer risk. Health care workers can thus help patients identify connections and establish coherence through the act of storytelling, by listening to their illness experiences as part of their life stories.

Does perceived risk predict breast cancer screening use? Findings from a prospective cohort study of female relatives from the Ontario site of the breast cancer family registry. Breast 2014; 23:482-8. [PMID: 24821458 DOI: 10.1016/j.breast.2014.04.001] [Citation(s) in RCA: 9] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/30/2013] [Revised: 04/03/2014] [Accepted: 04/04/2014] [Indexed: 11/21/2022] Open
Abstract
While the relationship between perceived risk and breast cancer screening use has been studied extensively, most studies are cross-sectional. We prospectively examined this relationship among 913 women, aged 25-72 with varying levels of familial breast cancer risk from the Ontario site of the Breast Cancer Family Registry. Associations between perceived lifetime breast cancer risk and subsequent use of mammography, clinical breast examination (CBE) and genetic testing were assessed using logistic regression. Overall, perceived risk did not predict subsequent use of mammography, CBE or genetic testing. Among women at moderate/high familial risk, those reporting a perceived risk greater than 50% were significantly less likely to have a CBE (odds ratio (OR) = 0.52, 95% confidence interval (CI): 0.30-0.91, p = 0.04), and non-significantly less likely to have a mammogram (OR = 0.70, 95% CI: 0.40-1.20, p = 0.70) or genetic test (OR = 0.61, 95% CI: 0.34-1.10, p = 0.09) compared to women reporting a perceived risk of 50%. In contrast, among women at low familial risk, those reporting a perceived risk greater than 50% were non-significantly more likely to have a mammogram (OR = 1.13, 95% CI: 0.59-2.16, p = 0.78), CBE (OR = 1.11, 95% CI: 0.63-1.95, p = 0.74) or genetic test (OR = 1.29, 95% CI: 0.50-3.33, p = 0.35) compared to women reporting a perceived risk of 50%. Perceived risk did not significantly predict screening use overall, however this relationship may be moderated by level of familial risk. Results may inform risk education and management strategies for women with varying levels of familial breast cancer risk.

Abstract
We report prospectively observed risk for breast cancer in breast cancer kindreds without a demonstrable BRCA1/2 mutation. According to family history, the optimal available member(s) of each breast cancer kindred attending our clinic was tested for BRCA mutations. Women in families without a demonstrable BRCA mutation were subjected to annual mammography. BRCA mutations were demonstrated in 496/2,118 (23 %) breast cancer kindreds. In families without a demonstrable BRCA mutation, a total of 3,161 healthy women aged 25-59 years were prospectively followed for 24,808 observation years. Sixty-four cancers were observed, compared to 34.0 expected (p < 0.01), arriving at a 7.9 % cumulative risk at age 60 compared to 4.0 % in the population [relative risk (RR) = 2.0]. Women with one mother or sister affected ≤50 years and with no other close relatives with breast cancer did not have increased risk (0 cancers observed and 0.6 expected at age 40, 11 cancers observed and 7.9 expected at age 60, p > 0.05). Excluding these, cumulative risk at 60 years was 8.8 % (RR = 2.2). The highest cumulative risk at 60 years was 11.4 %, found in families with two cases ≤55 years (RR = 2.8). In breast cancer kindreds without a demonstrable BRCA mutation, the risk for breast cancer in female first degree relatives was about twice the risk in the general population. Women with one early affected relative only did not have increased risk for early onset breast cancer, while those with more than one young affected relative had close to three times population risk.

Abstract
Although several studies have found screen-detected cancers in women with familial breast cancer risk have favorable prognostic features compared with symptomatic cancers, the impact of level of familial risk is unknown. A cohort of 899 first-degree female relatives of cases of breast cancer from the Ontario site of the Breast Cancer Family Registry was followed for 2 years. Logistic regression analyses compared diagnoses of breast cancer or benign breast disease (BBD) between women at high (n = 258, 28.7 %) versus low/moderate (n = 641, 71.3 %) familial risk. Similar analyses compared prognostic features of invasive cancers and BBD by level of familial risk and mammography screening status. Among 899 women, 44 (4.9 %) were diagnosed with invasive breast cancer and/or ductal carcinoma in situ, and 56 (6.2 %) with BBD. Women with high familial risk were significantly more likely to be diagnosed with breast cancer [odds ratio (OR) = 2.84, 95 % confidence interval (CI) 1.50-5.38] than low/moderate risk women, particularly if diagnosed at age ≥50 (OR = 2.99, 95 % CI 1.37-6.56) or screened with mammography (OR = 3.33, 95 % CI 1.54-7.18). High risk women were more likely to be diagnosed with BBD (OR = 1.94, 95 % CI 1.03-3.66). Level of familial risk was not associated with prognostic features. Cancers among unscreened women were larger (OR = 9.72, 95 % CI 1.01-93.61) and diagnosed at stage II or above (OR = 7.80, 95 % CI 1.18-51.50) compared with screen-detected cancers. Screening mammography may be effective for women with a first-degree family history of breast cancer, irrespective of level of familial risk.

Accuracy of Self-Reported Screening Mammography Use: Examining Recall among Female Relatives from the Ontario Site of the Breast Cancer Family Registry. ISRN ONCOLOGY 2013; 2013:810573.

Abstract
Evidence of the accuracy of self-reported mammography use among women with familial breast cancer risk is limited. This study examined the accuracy of self-reported screening mammography dates in a cohort of 1,114 female relatives of breast cancer cases, aged 26 to 73 from the Ontario site of the Breast Cancer Family Registry. Self-reported dates were compared to dates abstracted from imaging reports. Associations between inaccurate recall and subject characteristics were assessed using multinomial regression. Almost all women (95.2% at baseline, 98.5% at year 1, 99.8% at year 2) accurately reported their mammogram use within the previous 12 months. Women at low familial risk (OR = 1.77, 95% CI: 1.00–3.13), who reported 1 or fewer annual visits to a health professional (OR = 1.97, 95% CI: 1.15, 3.39), exhibited a lower perceived breast cancer risk (OR = 1.90, 95% CI: 1.15, 3.15), and reported a mammogram date more than 12 months previous (OR = 5.22, 95% CI: 3.10, 8.80), were significantly more likely to inaccurately recall their mammogram date. Women with varying levels of familial risk are accurate reporters of their mammogram use. These results present the first evidence of self-reported mammography recall accuracy among women with varying levels of familial risk.

Abstract
OBJECTIVES A small positive association has been consistently demonstrated between perceived breast cancer risk and mammography use. Evidence specific to women with familial breast cancer risk has not been previously reviewed. METHODS A literature search was conducted. 186 studies were identified for abstract/full-text review, of which 10 articles were included. Manual searching identified 10 additional articles. Twenty articles examining the association between perceived breast cancer risk and adherence to mammography, clinical breast examination (CBE) or breast self-examination (BSE) guidelines among women with familial breast cancer risk were reviewed. Studies were classified according to screening modality, categorized by finding and ordered by year of publication. Studies assessing mammography were further classified according to the applied method of measuring perceived risk. RESULTS Our review found a weak positive association between higher perceived risk and adherence to mammography guidelines among women with familial breast cancer risk. Consistent associations between perceived risk and adherence to CBE and BSE guidelines were not observed. CONCLUSIONS Our ability to understand the relationship between perceived breast cancer risk and adherence to breast screening guidelines is limited, because most previous research is cross-sectional. Future studies with prospective methodologies that use consistent measurement methods and are adequately powered are warranted.

Abstract
Penetrances of BRCA1 and BRCA2 mutations have been derived from retrospective studies, implying the possibility of ascertainment biases to influence the results. We have followed women at risk for breast and/or ovarian cancer for two decades, and report the prospectively observed age-related annual incidence rates to contract breast or ovarian cancer for women with deleterious BRCA1 or BRCA2 mutations based on 4830 observation years. Patients were grouped according to mutation, age and having/not having had previous cancer. In women not having had previous cancer and aged 40-59 years, the annual incidence rate to contract breast or ovarian cancer in those having the most frequent BRCA1 founder mutations was 4.0%, for women in this age group and with less frequent BRCA1 mutations annual incidence rate was 5.9%, and for women with BRCA2 mutations 3.5%. The observed figures may be used for genetic counseling of healthy mutation carriers in the respective age groups. The results may indicate that less frequent BRCA1 mutations have higher penetrances than BRCA1 founder mutations.

Abstract
GOALS OF WORK Genetic counseling for hereditary cancer is expected to involve a growing number of individuals in the near future since an increasing number of genetic tests are offered. This study was designed to identify psychosocial variables predicting distress after genetic investigation and genetic counseling (GC) in order to develop new counseling strategies. MATERIALS AND METHODS A prospective multi-site study was undertaken on 214 patients undergoing GC for hereditary cancer to explore the relationships between socio-demographic variables, medical variables, social support, self-efficacy, physical functioning, satisfaction with GC, the level of worry after GC, results of genetic testing, and the course and outcomes of distress. Distress was measured with the Impact of Event Scale, which includes subscales of intrusion and avoidance. Patients completed questionnaires mailed to them before and after GC. MAIN RESULTS The mean level of intrusion and avoidance was moderate, even though one quarter of participants reported a severe level of intrusion at baseline. Subjects with a low level of self-efficacy at baseline and high level of worry immediately after GC seemed to be vulnerable to both intrusion and avoidance. Lower level of intrusion was also associated with having a first-degree relative with cancer, while a lower avoidance level was associated with a higher level of education, having cancer, more social support, and higher satisfaction with GC. CONCLUSIONS In this study, subjects who had lower level of self-efficacy at baseline and a high level of worry immediately after GC seemed to be vulnerable to both intrusion and avoidance in this study.

[PMID: 18295433 DOI: 10.1016/j.pec.2008.01.008] [Citation(s) in RCA: 16] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/05/2007] [Revised: 12/19/2007] [Accepted: 01/07/2008] [Indexed: 05/25/2023]
Abstract
OBJECTIVES The main aims of the study were to investigate changes in anxiety and depression over time in subjects attending genetic counseling (GC) for hereditary cancer, and secondly, to identify psychological, social, and medical variables associated with the course and outcome of anxiety and depression. METHODS Of 275 eligible individuals, 221 consented to participate, 214 returned the baseline questionnaire, and were included in a prospective multi-center study. Questionnaires were mailed to the subjects before and after the GC. RESULTS The mean values for anxiety and depression were quite low at all assessments. Mixed linear analyzes revealed that both anxiety and depression declined over time. Higher age, GC-related self-efficacy, and social support were associated with lower levels of anxiety. More social support, satisfaction with GC, self-rated physical function, and GC-related self-efficacy were associated with lower levels of depression. The effects of social support on both anxiety and depression had a significant interaction with time. CONCLUSION The results support the buffer theory, which proposes that social support acts as a buffer, protecting people from the potentially pathogenic influence of stressful life events, such as GC. PRACTICE IMPLICATIONS Subjects with less social support and less GC-related self-efficacy seem to be more vulnerable to anxiety and depression and should be offered extra attention by counselors.

Abstract
This is a cross-sectional study of coping strategies in 174 healthy women who fulfill clinical criteria for familial breast/ovarian cancer in the absence of demonstrated mutations (ADM) compared to 68 healthy women with BRCA1 carrier status. Both groups got a mailed questionnaire after genetic counseling and testing, respectively. The questionnaire included demographic and cancer-related variables as well as the Hospital Anxiety and Depression Scale (HADS) and the Coping Orientation to Problems Experienced Scale (COPE). In both groups 24% of the women had an anxiety disorder. Coping strategies which helped the women to accept and make the best out of their situation were most frequently applied in both the ADM and the carrier groups. Compared to the carrier group, the ADM group had higher mean levels on both emotion-focused and problem-focused strategies. The emotion-focused strategies were all significantly associated with presence of HADS-defined anxiety disorder in the ADM group. In the carrier group problem-focused strategies were significantly associated with increased prevalence of such anxiety disorder. In multivariate analysis 'focus on emotions' was significantly associated with increased prevalence of HADS-defined anxiety disorder in both groups, and 'acceptance' was associated with reduced prevalence in both groups.

Abstract
Women with germline BRCA1 mutation have a significant risk of breast and/or ovarian cancer. Prophylactic bilateral mastectomy (PBM) and prophylactic bilateral salpingo-oophorectomy (PBSO) prevent cancer in mutation carriers. The cost-effectiveness of PBSO (age of 35 years) with or without PBM five years earlier was compared to a no intervention setting employing a marginal cost analysis. National data on cancer incidence, mortality rates and costs were implemented together with observed Norwegian BRCA1 data in a Markov model and PBSO was assumed to reduce the risk of ovarian cancer by 90%. A 3% discount rate was used. The additional health care cost per mutation carrier undergoing PBSO and PBM was euro 15,784, and 6.4 discounted life years gained (LYG) was indicated (PBSO alone with 100% acceptance 3.1 LYG). The additional cost per LYG was euro 1973 (PBSO alone euro 1749/LYG). Including all resource use, the figure was a cost of euro 496 and euro 1284 per LYG, respectively. PBSO with or without PBM in BRCA1 mutation carriers is cost-effective. A testing of all incident breast cancers to identify mutation carrying families should be explored.

Abstract
AIM The aim of this longitudinal study was to explore both levels of and factors predictive of psychological and cancer-specific distress in women with demonstrated BRCA1 mutations belonging to families with hereditary breast/ovarian cancer (HBOC). METHODS We included 214 women from HBOC families who had BRCA1 testing, and who were examined with a mailed questionnaire at pre-test (T1), 6 weeks after getting the test result (T2) and 18 months later (T3). Self-rating instruments for psychological distress, cancer-specific distress and personality traits were used. RESULTS Hardly any significant changes were observed concerning the levels of psychological and cancer-specific distress from T1 via T2 to T3 for the total group or those with carrier or non-carrier status, while women with cancer had a significant reduction of cancer-specific distress over time. The pre-test levels of psychological and cancer-specific distress were significant and strong predictors of these types of distress at T3. The personality trait of neuroticism made a significant contribution to both types of distress at pre-test, and a small separate contribution to distress at T3. Carrier status, history of personal cancer, pre-test levels of optimism or multidimensional health locus of control did not significantly predict distress at T3. CONCLUSIONS Genetic testing or test results were not found to induce psychological or cancer-specific psychological distress at long-term. Neuroticism had a decisive influence at both pre-test and long-term levels of distress.

Abstract
We wanted to compare the sensitivities of breast magnetic resonance imaging (MRI) and the conventional screening programme consisting of mammography (XRM) +/- ultrasound for early diagnosis of breast cancer in BRCA1/2 mutation carriers. BRCA1/2 mutation carriers were examined prospectively by both breast MRI and XRM +/- ultrasound. Eight hundred and sixty-seven MRI examinations were carried out in 445 BRCA1 and 46 BRCA2 mutation carriers. A total of 25 cancers were observed, five (20%) as interval cancers. At the time of diagnosis, sensitivity to detect cancer was 19/22=86% for MRI and 12/24=50% for XRM. Twenty-one were examined by both methods at the time of diagnosis. In the19 BRCA1 mutation carriers among them, MRI had a sensitivity of 1/3(33%) to diagnose DCIS and 15/16 (94%) among the invasive cancers. For XRM the sensitivities were 1/3(33%) for DCIS, 3/7(42%) for pT1b, 3/6(50%) for pT1c, and 3/3/100%) for pT2. In the two BRCA2 mutation carriers, both were demonstrated by breast MRI, neither was detected by XRM. Breast MRI had increased sensitivity compared to XRM to diagnose all cancers staged less than pT2.

Abstract
Ten BRCA mutations were demonstrated to be frequent in the Norwegian population. We present maps verifying the uneven distribution of prevalences according to municipality. We tested incident breast cancer cases treated in Mid-Norway from 1999 onwards for these mutations. Uptake of testing was 97% and 2.5% were demonstrated to be mutation carriers. Ten (77%) were outside families previously known to carry a mutation. Ten (77%) did not meet clinical criteria to be selected for mutation testing. We tested incident ovarian cancer cases in South-West Norway from 2001 onwards. Uptake of testing was 80% and 23% were mutation carriers. Twenty-one (88%) were outside families previously known. Twelve (67%) did not meet clinical criteria to be selected for testing. All patients with mutation collaborated actively to give our offer of predictive genetic testing to their relatives. No complaint on the activity was received.

Abstract
In this multi center study, genetic counseling for hereditary cancer was evaluated by assessing patients' worry, perceived risk of developing cancer and satisfaction with genetic counseling. An overall aim was to identify characteristics of vulnerable patients in order to customize genetic counseling. In addition, agreement between patients' and counselors' scores was measured. A total of 275 Norwegian patients were consecutively recruited, and 213 completed questionnaires before and after genetic counseling. Patients' perceived risk decreased after the genetic counseling session. There was incongruence between risk perception expressed as a percentage and in words. Patients were significantly less worried after counseling. Higher levels of worry were predicted by low instrumental satisfaction with counseling, high degree of perceived risk of developing cancer and younger age. In conclusion, counselors met the patients' psychological needs to a satisfactory degree during counseling. However, patients did not fully understand their risk of developing cancer.

Abstract
Cowden syndrome (multiple hamartoma syndrome, MIM 158350) is an early onset syndrome characterized by multiple hamartomas in the skin, mucous membranes, breast, thyroid and endometrium. Patients with Cowden syndrome have increased risk of breast cancer, thyroid cancer and endometrial cancer. In 1997 germline mutations in PTEN were demonstrated to cause Cowden syndrome. We report the results of diagnostic and predictive testing in all families with Cowden syndrome or suspected Cowden syndrome registered at the Norwegian cancer family clinics. PTEN mutations were found in all six families meeting the clinical criteria for Cowden syndrome, in none of the two families assumed to have Cowden syndrome but not fulfilling the criteria, and in none of the eight families selected in our computerized medical files to have a combination of breast and thyroid cancers. Age-related penetrances for the various neoplasms are given. All families but one were small and de novo mutations were found.

Abstract
BACKGROUND Screening mammography is associated with a small dose of radiation to the breast, and women with increased genetic risk might be particularly sensitive to the DNA-damaging effects of ionising radiation. We aimed to assess whether exposure to ionising radiation through mammography screening was associated with risk of breast cancer in BRCA1 or BRCA2 mutation carriers. METHODS We identified 1600 cases of breast cancer and 1600 controls without breast cancer who were matched for BRCA mutation, date of birth (within 1 year), and country of residence from an international registry of BRCA1 and BRCA2 mutation carriers. We used a questionnaire to inquire about whether participants had ever had screening mammography, and, if so, the age at which they first had the procedure. RESULTS We found no association between ever having screening mammography and risk of breast cancer (odds ratio [OR] 1.03 [95% CI 0.85-1.25], adjusted for parity, oral-contraceptive use, ethnic origin, and bilateral oophorectomy). The association was much the same for BRCA1 mutation carriers and BRCA2 mutation carriers (1.04 [0.84-1.29] vs 1.06 [0.67-1.66], respectively, adjusted for parity, oral-contraceptive use, ethnic origin, and bilateral oophorectomy). INTERPRETATION These findings do not lend support to the idea that exposure to ionising radiation through routine screening mammography contributes substantially to the burden of breast cancer in BRCA1 and BRCA2 mutation carriers. Prospective studies are needed to confirm the results of this initial report, and, where possible, these studies should assess a more appropriate endpoint of total exposure.

Abstract
BACKGROUND Although quality of life (QoL) and mental distress in women belonging to familial cancer families have been studied, little is known on these matters in women with absence of demonstrated mutations. The aim of this study was to examine QoL and cancer-related distress in such women. METHODS About 330 women at risk for familial cancers in the absence of demonstrated mutations were invited to the study. About 239 women (72%) (risk group) completed the Short Form 12 (SF-12) and the Impact of Event Scale (IES). The SF-12-findings were compared to the age-adjusted findings from the general female population (controls). RESULTS The risk group had significantly better physical QoL than controls, while no significant difference was found for mental QoL. Within the risk group the type of familial cancer did not make a significant difference in QoL, but to have a father with cancer or a deceased parent, was associated with increased risk of being a case with low QoL. Mental QoL showed moderate correlation with cancer-related distress. CONCLUSIONS Women belonging to familial cancer families in the absence of demonstrated mutations had at least as good QoL as controls in spite of living with a permanent cancer-related threat.

Abstract
BACKGROUND Although the use of mammography on at regular intervals can save lives, not all women obtain the repeat mammography recommended in guidelines. OBJECTIVE To assess the associations between routine mammography use, perceived cancer risk, and actual projected cancer risk. METHODS We include women who were 45 to 75 years of age and who had responded to the 2000 National Health Interview Survey. Women who reported that they believed their risk of getting cancer in the future was "medium" or "high" were considered jointly as "medium/high-risk perception.""Routine mammography use" was defined as having > or =3 mammograms in the previous 6 years. We used logistic regression to determine the independent relation between cancer risk perception, projected breast cancer risk, and routine mammography use. RESULTS Of the 6,002 women who met our inclusion criteria, 63.1% reported routine mammography use. About 76% of women in the highest quartile of projected breast cancer risk reported routine mammography use, compared with only 68%, 64%, and 51% in the third, second, and first quartiles, respectively (P<.001 chi-square test for trend). After adjusting for indicators of access to care, sociodemographic and behavioral factors, and perceived cancer risk, women in the highest quartiles of projected cancer risk were significantly more likely to report routine mammogram use than women in the lowest quartile (odds ratio [OR] of women in third and fourth quartiles were 1.57 [1.24 to 1.99], and 2.23 [1.73 to 2.87] vs the lowest quartile, respectively). Women with a higher perceived cancer risk were significantly more likely to undergo routine mammography (adjusted OR: 1.29 [1.12 to 1.48] P=.001). Cancer risk perceptions tended to be higher among women who were younger age, obese, smokers, depressed, or reported one of the following breast cancer risk factors: family breast cancer history, prior abnormal mammogram, and early age at menarche. CONCLUSION Actual and perceived risk were independent predictors of routine mammography use, suggesting that efforts to incorporate risk profiles into clinical decision making may need to involve more than just relaying information about projected risks to patients, but also to explore how risk perceptions can be affected by this information.

Abstract
OBJECTIVE The aim of the study was to estimate the prevalence of hereditary cancers and the need for surveillance in Telemark county, Norway. MATERIAL AND METHODS All persons attending the Norwegian Colorectal Cancer Prevention (NORCCAP) trial in Telemark were interviewed about cases of cancer in the family. Diagnoses were verified, pedigrees constructed and families classified according to preset criteria aiming at identifying hereditary cancer. Mutation analyses were performed in kindreds at risk for breast cancers when possible. Immunohistochemistry of tumors in assumed inherited colorectal cancer families was undertaken. RESULTS The screening examination was attended by 7,224 persons among whom 2,866 had cancer in the family. Of these, 2,479 had no suspicion of any known inherited cancer syndrome. Family information questionnaires were mailed to 387 persons and returned by 191. Sixty-four of these 191 met the clinical criteria for familial cancer by family history after verification of diagnoses. Observed prevalences for being at risk for hereditary breast and breast-ovarian cancer (HBOC) or hereditary non-polyposis colorectal cancer (HNPCC) were 2.8 per thousand and 0.77 per thousand, respectively. CONCLUSIONS The number of colonoscopies and mammograms obtained per year serving those who needed them was limited and reduced by clinical genetic work-up from 2,866 with a family history of cancer to 64 proven cases. Continued surveillance of an unnecessarily high number leads to unjustified cancer worry, is costly and uses up health-care facilities. Genetic work-up is a one-time job that reduces input numbers to surveillance programs, provides a starting-point for mutation testing and is economically cost beneficial if inherited cancers are prevented or cured by the health-care programs offered.

Abstract
AIM To examine psychological distress in women at risk of familial breast-ovarian cancer (FBOC) or hereditary non-polyposis colorectal cancer (HNPCC) with absence of demonstrated mutations in the family (unknown mutation). MATERIALS AND METHODS Two-hundred and fifty three consecutive women at risk of FBOC and 77 at risk of HNPCC and with no present or past history of cancer. They were aware of their risk and had received genetic counseling. Comparisons were made between these two groups, normal controls, and women who were identified to be BRCA1 mutation carriers. The questionnaires Beck Hopelessness Scale (BHS), General Health Questionnaire (GHQ-28), Hospital Anxiety and Depression Scale (HADS) and Impact of Event Scale (IES) were employed to assess psychological distress. RESULTS No significant differences concerning psychological distress were observed between women with FBOC and women with HNPCC. Compared to mutation carriers for BRCA1, the level of anxiety and depression was significantly higher in the FBOC group with absence of demonstrated mutation. Compared to normal controls, the level of anxiety was higher, while the level of depression was lower in the groups with unknown mutation. CONCLUSIONS Women in the absence of demonstrated mutations have higher anxiety and depression levels than women with known mutation-carrier status. Access to genetic testing may be of psychologically benefit to women at risk for FBOC or HNPCC.

Abstract
BACKGROUND Breast cancer is increasing in Indonesia and other developing countries. Germline mutations in the BRCA1/2 genes are most strongly associated with a high risk for breast cancer development. There have been no reports on BRCA1/2 gene mutations in the Indonesian population. Genetic research yielding insight into mutations affecting the Indonesian population can help in risk assessment of individual patients. AIMS To screen the BRCA1/2 genes for mutations in early onset Indonesian breast cancer patients and their families with a new, simple, and sensitive BRCA1/2 mutation screening strategy based on denaturing gradient gel electrophoresis (DGGE) and targeted sequencing. METHODS DNA was isolated from the blood of four Indonesian breast cancer patients from high risk families and seven family members, and the polymerase chain reaction was performed with specially designed primers throughout the BRCA1/2 coding sequences to produce fragments suitable for pooled DGGE analysis. The aberrantly migrating samples were reamplified and sequenced. RESULTS Two mutations were found in exons 13 and 16 of BRCA1 and two mutations in exons 2 and 14 of BRCA2, which turned out to be established polymorphisms according to the Breast Cancer Information Core. In addition, a novel 6 bp deletion in exon 11, leading to a premature stop, was found in BRCA2. CONCLUSION Pooled DGGE and targeted sequencing revealed four BRCA1/2 polymorphisms and one novel BRCA2 mutation in a group of Indonesian patients at high risk of hereditary breast cancer. This illustrates that the proposed method is sensitive and particularly suited for screening unknown populations.

Costs and benefits are ill-defined terms; this review discusses some interpretations and some ways of assessing costs and benefits. Cost-benefit calculation is a misconception in health care, in that costs should be considered together with what the patients gain in terms of prolonged life and life quality. In the emerging commercialization of Western health care, however, money benefit is to be calculated in order to ask for funding. As professionals we are dealing with inherited breast cancer. We come to know the families and the individual women within these families. We care, we cure, we prevent and we are gaining knowledge. We are doing good, not harm. We are profoundly involved, and we are so deeply and personally involved that we may not even try to be objective in a debate on choosing between our patients and patients cared for by others. As we present our arguments, society has to decide. There is no argument to provide service for other inherited disorders based on ethical standards alone, and to deprive women at risk for breast cancer the life-saving health service they need because of money costs. The money needed is based on a number of rapidly fluctuating factors: the most stable costs are genetic counseling and physical examinations to demonstrate disease, while laboratory costs are rapidly decreasing. The overall conclusion is that economical cost-benefit analysis as an argument for our activity is outside our professional ethics, and should never become a reason for our continued endeavors.

Abstract
Inherited breast-ovarian cancer was described in 1866. The underlying genetic defects in BRCA1/2 were demonstrated 128 years later. We now have 10 years of experience with genetic testing in BRCA kindreds. The majority of breast cancer kindreds (familial breast cancer) do not demonstrate ovarian cancer and are not associated with BRCA mutations. The effect of early diagnosis and treatment is monitored through international collaborations.BRCA1-associated breast cancer is biologically different from other breast cancers, including a worse prognosis. BRCA2-associated breast cancer is, beside early onset, in many ways similar to sporadic breast cancer. Mammography screening of the high risk groups aiming at early diagnosis and treatment, seems promising for familial breast cancer and for BRCA2-associated breast cancer, but numbers included for BRCA2 carriers are limited. BRCA1-carriers have worse prognosis, and the potential benefit of MRI for early diagnosis is now being explored. Early diagnosis and treatment of ovarian cancer does not substantially improve survival, and prophylactic oophorectomy at the end of childbearing ages is advocated. Prophylactic mastectomy is debated, and we may await the results of MRI trials before recommending this option. Familial breast cancer and BRCA2-associated breast cancers are often oestrogen receptor positive, and may be prevented by oestrogen blockers/inhibitors. Oophorectomy prevents ovarian cancer, and may possibly prevent both receptor positive and receptor negative breast cancer as well, also while using HRT. Oral contraceptives may reduce ovarian cancer risk and increase breast cancer risk, irrespective of initial risk and genetic subgroup.

Abstract
This study was undertaken to examine transmission of information to first-degree relatives of BRCA1 mutation carriers and uptake of genetic testing. The intention was to consider revision of current legislation related to privacy if information on life-saving health care was not disseminated to at-risk family members. The Norwegian Radium Hospital provides clinical genetics services for families at high risk for hereditary breast and ovarian cancer. Together with major hospitals nationwide we provide medical surveillance. Nearly all expenses are covered by the National Health insurance. Because of the high number of families with founder mutations in BRCA1, we are in a unique position to gather information about these groups. Within a consecutive series, we identified 75 BRCA1 mutation carriers and registered information transmission and uptake of genetic testing 6 months or more after the index mutation carriers had been informed about their mutation status. These 75 BRCA1 mutation carriers had 172 living first-degree relatives, aged 18 years or older (84 females, 88 males). Forty-four out of 54 (81.5%) of females over 30 had opted for genetic testing. The testing rate among all relatives was 43%. At any age, 63 % of the females underwent genetic testing compared with 24% of the males (p<0.05%). The overwhelming majority of adult females at risk opted for genetic testing. Males with daughters more frequently than males without daughters asked for testing. The findings give neither reason to reconsider legislation on privacy, nor for us to consider more aggressive methods of contacting relatives.

Abstract
We aimed to describe the penetrances of the four Norwegian founder mutations in BRCA1 (816delGT, 1135insA, 1675delA and 3347delAG) with regard to breast and ovarian cancers in families ascertained through cancer family clinics or a consecutive series of women with breast or ovarian cancer. We have extended the families as far as possible and tested all family members that asked for genetic testing. Penetrance is based upon counting the mutation carriers. The series contains sufficient numbers of mutation carriers to minimise variation in the estimates due to a limited sample set. The penetrances for all four mutations were high, both with respect to breast and ovarian cancers. This is in accordance with other reports from cancer family clinics, but contrasts with reports from population-based series of mutation carriers. Risks of first cancer (breast or ovarian), breast cancer, and ovarian cancer at age 50 years were 43, 30 and 17%, respectively. Corresponding risks at age 70 years were 84, 58 and 58%. Risks for breast cancer before age 30 years and for ovarian cancer before 35 years were low. Penetrances with regard to ovarian cancer were different for the four mutations. The risk of ovarian cancer was doubled in carriers of the 1675delA mutation when compared with the 816delGT mutation (24 versus 12% at age 50 years, P=0.004). The mutations analysed are high penetrance alleles. No differences in penetrance between the series ascertained through the cancer family clinic or the series of consecutive cancer patients was observed. There are discrepancies between our findings and the low penetrances reported for other mutations in other populations. This may be due to methodological differences, but may reflect differences between mutations and/or modifying factors in different populations.

Abstract
The demand for genetic services by women with a family history of breast cancer has increased exponentially over the last few years. It is important that risks to women are accurately assessed and that processes are in place for appropriate counselling and management. The classification of risk into average, moderate, and high, depending upon the assessed lifetime risk of breast cancer, allows for the management of moderate risk women within cancer units and high risk women within the regional genetic centres. Management of high risk women includes discussion of options including screening, chemoprevention, and preventive surgery. The majority of these options are still unproven in the long term and continuing research is needed for their evaluation. Mutation screening and predictive testing are now a reality for a minority of families, allowing for a more informed basis for decisions regarding management options.

Abstract
Dedicated clinics have been established for the early diagnosis and treatment of women at risk for inherited breast cancer, but the effects of such interventions are currently unproven. This second report on prospectively diagnosed inherited breast cancer from the European collaborating centres supports the previous conclusions and adds information on genetic heterogeneity and the effect of oophorectomy. Of 249 patients, 20% had carcinoma in situ (CIS), 54% had infiltrating cancer without spread (CaN0) and 26% had cancer with spread (CaN+). Five-year survival was 100% for CIS, 94% for CaN0 and 72% for CaN+ (p = 0.007). Thirty-six patients had BRCA1 mutations, and 8 had BRCA2 mutations. Presence of BRCA1 mutation was associated with infiltrating cancer, high grade and lack of oestrogen receptor (p < 0.05 for all 3 characteristics). For BRCA1 mutation carriers, 5-year survival was 63% vs. 91% for noncarriers (p = 0.04). For CaN0 patients, mutation carriers had 75% 5-year disease-free survival vs. 96% for noncarriers (p = 0.01). Twenty-one of the mutation carriers had undergone prophylactic oophorectomy, prior to or within 6 months of diagnosis in 13 cases. All but 1 relapse occurred in the 15 who had kept their ovaries, (p < 0.01); no relapse occurred in those who had removed the ovaries within 6 months (p = 0.04) Contralateral cancer was more frequently observed in mutation noncarriers, but this finding did not reach statistical significance. Our findings support the concept that BRCA1 cancer is biologically different from other inherited breast cancers. While current screening protocols appear satisfactory for the majority of women at risk of familial breast cancer, this may not be the case for BRCA1 mutation carriers. The observed effect of oophorectomy was striking.

Abstract
Inherited breast cancer is a heterogenous group of diseases. We examined this heterogeneity in a prospective series of inherited breast and ovarian cancers, previously demonstrated to include 84% of inherited cancers. Ninety-two tumours (65 breast and 27 ovarian) in 82 patients from 70 kindreds were prospectively diagnosed. Fifteen of the breast cancers were in situ, 50 were infiltrating. 40 (49%) of the 82 women carried a BRCA1 mutation, whereas no mutation in BRCA2 was found. Approximately, two-thirds of the BRCA1 mutation carriers had one of the four most frequent Norwegian founder mutations. Ninety-five per cent of the epithelial ovarian cancers occurred in BRCA1 mutation carrying women versus 38% of infiltrating breast cancers and 7% of carcinoma in situ of the breast. The BRCA1 syndrome was phenotypically distinct with invasive, high grade, oestrogen receptor-negative breast cancers and epithelial ovarian cancers. Non-BRCA1/2 inherited breast cancers included carcinoma in situ and lobular carcinoma and were frequently bilateral. Non-BRCA1/2 inherited breast cancer is not associated with epithelial ovarian cancer and in breast cancers has distinct biological characteristics, indicating that the different subgroups of inherited breast cancer may need different healthcare services.
