The objective of this study was to measure the psychological impact of tumour genetic testing among individuals with a new diagnosis of HGSOC. Participants had a new diagnosis of HGSOC and received reflex BRCA1/2 tumour genetic testing as a component of their care. Eligible individuals were recruited from two oncology centres in Toronto, Canada. One week after disclosure of tumour genetic test results, consenting participants were asked to complete a questionnaire that measured cancer-related distress, dispositional optimism, knowledge of hereditary breast/ovarian cancer, recall of tumour genetic test results, satisfaction, and the psychological impact of receiving tumour genetic test results. The Multidimensional Impact of Cancer Risk Assessment (MICRA) questionnaire was used to measure the psychological impact of tumour genetic testing. 76 individuals completed the study survey; 13 said they did not receive their tumour test results. Of the remaining 63 participants, the average MICRA score was 26.8 (SD = 16.3). Higher total MICRA scores were seen among those with children (p = 0.02), who received treatment with primary surgery (p = 0.02), and had higher reported cancer-related distress (p < 0.001). Higher dispositional optimism (p < 0.001) and increasing age (p = 0.03) were associated with lower total MICRA scores. Most (83.5%) participants reported being satisfied/highly satisfied with having tumour testing completed; however, 40.8% could not accurately recall their tumor test results. This study is the first to assess psychological outcomes following reflex BRCA1/2 tumour genetic testing in women newly diagnosed with HGSOC. Increased dispositional optimism provided a protective effect, while increased cancer-related distress increased the psychological impact of tumour genetic testing. Educational resources are needed to help increase patient understanding and recall of tumour results, particularly when tumour genetic testing includes analysis of genes that may have implications for hereditary cancer risk. Additional research is required to better understand the patient experience of reflex tumour genetic testing.","PeriodicalId":55058,"journal":{"name":"Hereditary Cancer in Clinical Practice","volume":null,"pages":null},"PeriodicalIF":1.7,"publicationDate":"2022-04-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138509841","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Delineating the role of osteoprotegerin as a marker of breast cancer risk among women with a BRCA1 mutation","authors":"Park, Sarah Sohyun, Uzelac, Aleksandra, Kotsopoulos, Joanne","doi":"10.1186/s13053-022-00223-3","DOIUrl":"https://doi.org/10.1186/s13053-022-00223-3","url":null,"abstract":"Women with a pathogenic germline mutation in the BRCA1 gene face a very high lifetime risk of developing breast cancer, estimated at 72% by age 80. Prophylactic bilateral mastectomy is the only effective way to lower their risk; however, most women with a mutation opt for intensive screening with annual MRI and mammography. Given that the BRCA1 gene was identified over 20 years ago, there is a need to identify a novel non-surgical approach to hereditary breast cancer prevention. Here, we provide a review of the emerging preclinical and epidemiologic evidence implicating the dysregulation of progesterone-mediated receptor activator of nuclear factor κB (RANK) signaling in the pathogenesis of BRCA1-associated breast cancer. Experimental studies have demonstrated that RANK inhibition suppresses Brca1-mammary tumorigenesis, suggesting a potential target for prevention. Data from studies conducted among women with a BRCA1 mutation further support this pathway in BRCA1-associated breast cancer development. Progesterone-containing (but not estrogen-alone) hormone replacement therapy is associated with an increased risk of breast cancer in women with a BRCA1 mutation. Furthermore, BRCA1 mutation carriers have significantly lower levels of circulating osteoprotegerin (OPG), the decoy receptor for RANK-ligand (RANKL) and thus endogenous inhibitor of RANK signaling. OPG levels may be associated with the risk of disease, suggesting a role of this protein as a potential biomarker of breast cancer risk. This may improve upon current risk prediction models, stratifying women at the highest risk of developing the disease, and further identify those who may be targets for anti-RANKL chemoprevention. Collectively, the evidence supports therapeutic inhibition of the RANK pathway for the primary prevention of BRCA1-associated breast cancer, which may generate unique prevention strategies (without prophylactic surgery) and enhance quality of life.","PeriodicalId":55058,"journal":{"name":"Hereditary Cancer in Clinical Practice","volume":null,"pages":null},"PeriodicalIF":1.7,"publicationDate":"2022-04-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138509842","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
