- Abstract
Background: Enthusiasm for precision oncology may obscure the psychosocial and ethical considerations associated with the implementation of tumor genetic sequencing., Methods: Patients with advanced cancer undergoing tumor-only genetic sequencing in the National Cancer Institute Molecular Analysis for Therapy Choice (MATCH) trial were randomized to a web-based genetic education intervention or usual care. The primary outcomes were knowledge, anxiety, depression, and cancer-specific distress collected at baseline (T0), posteducation (T1) and after results (T2). Two-sided, 2-sample t tests and univariate and multivariable generalized linear models were used., Results: Five hundred ninety-four patients (80% from NCI Community Oncology Research Program sites) were randomized to the web intervention (n = 293) or usual care (n = 301) before the receipt of results. Patients in the intervention arm had greater increases in knowledge (P for T1-T0 < .0001; P for T2-T0 = .003), but there were no significant differences in distress outcomes. In unadjusted moderator analyses, there was a decrease in cancer-specific distress among women (T0-T1) in the intervention arm but not among men. Patients with lower health literacy in the intervention arm had greater increases in cancer-specific distress and less decline in general anxiety (T0-T1) and greater increases in depression (T0-T2) in comparison with those receiving usual care., Conclusions: Web-based genetic education before tumor-only sequencing results increases patient understanding and reduces distress in women. Refinements to the intervention could benefit low-literacy groups and men., (© 2021 The Authors. Cancer published by Wiley Periodicals LLC on behalf of American Cancer Society.)

- Abstract
Background: Breast cancer therapies are associated with a risk of cardiac dysfunction, most commonly defined by changes in left ventricular ejection fraction (LVEF). Recently, the authors identified 3 classes of LVEF change after exposure to anthracyclines and/or trastuzumab using latent class growth modeling. The objective of the current study was to characterize the clinical, biochemical, and functional profiles associated with LVEF trajectory class membership., Methods: Transthoracic echocardiography and biomarker assessments were performed and questionnaires were administered at standardized intervals in a longitudinal cohort of 314 patients with breast cancer who were treated with anthracyclines and/or trastuzumab. Univariable and multivariable multinomial regression analyses evaluated associations between baseline variables and LVEF trajectory class membership. Generalized estimating equations were used to define mean changes in cardiovascular measures over time within each class., Results: Among the 3 distinct subgroups of LVEF changes identified (stable [class 1]; modest, persistent decline [class 2]; and significant early decline followed by partial recovery [class 3]), higher baseline LVEF, radiotherapy, and sequential therapy with anthracyclines and/or trastuzumab were associated with class 2 or 3 membership. Sustained abnormalities in longitudinal strain and N-terminal pro-B-type natriuretic peptide (NT-proBNP) were observed in patients in class 2, as were heart failure symptoms. Similar abnormalities were observed in patients in class 3, but there was a trend toward recovery, particularly for longitudinal strain., Conclusions: Patients with modest, persistent LVEF declines experienced sustained abnormalities in imaging and biochemical markers of cardiac function and heart failure symptoms. Further investigation is needed to characterize the long-term risk of heart failure, particularly in those with modest LVEF declines., (© 2019 American Cancer Society.)

- Abstract
Background: BRCA1/2 testing is not recommended for children, as risk reduction measures and screening are not generally recommended before 25 years old (YO). Little is known about the prevalence and predictors of parent communication to offspring and how offspring respond to this communication., Methods: Semi-structured interviews were conducted with parents who had BRCA1/2 testing and at least 1 child <25 YO. Logistic regressions were utilized to evaluate associations with communication. Framework analysis was utilized to analyze open-ended responses., Results: A total of 253 parents completed interviews (61% response rate), reporting on 505 offspring. Twenty-nine percent of parents were BRCA1/2 mutation carriers. Three hundred thirty-four (66%) offspring learned of their parent's test result. Older offspring age (P ≤ .01), offspring gender (female, P = .05), parents' negative test result (P = .03), and parents' education (high school only, P = .02) were associated with communication to offspring. The most frequently reported initial offspring responses were neutral (41%) or relief (28%). Thirteen percent of offspring were reported to experience concern or distress (11%) in response to parental communication of their test results. Distress was more frequently perceived among offspring learning of their parent's BRCA1/2 positive or variant of uncertain significance result., Conclusions: Many parents communicate their BRCA1/2 test results to young offspring. Parents' perceptions of offspring responses appear to vary by offspring age and parent test result. A better understanding of how young offspring respond to information about hereditary risk for adult cancer could provide opportunities to optimize adaptive psychosocial responses to risk information and performance of health behaviors, in adolescence and throughout an at-risk life span., (Copyright © 2012 American Cancer Society.)

- Abstract
Increased availability and heightened consumer awareness of "cancer genes" has increased consumer interest in, and demand for breast cancer risk assessment, and thus a pressing need for providers to identify effective, efficient methods of communicating complicated genetic information to consumers and their potentially at-risk relatives. With increasing direct-to-consumer and -physician marketing of predictive genetic tests, there has been considerable growth in web- and telephone-based genetic services. There is urgent need to further evaluate the psychosocial and behavioral outcomes (i.e., risks and benefits) of telephone and web-based methods of delivery before they become fully incorporated into clinical care models. Given the implications of genetic test results for family members, and the inherent conflicts in health care providers' dual responsibilities to protect patient privacy and to "warn" those at-risk, new models for communicating risk to at-risk relatives are emerging. Additional controversies arise when the at-risk relative is a minor. Research evaluating the impact of communicating genetic risk to offspring is necessary to inform optimal communication of genetic risk for breast cancer across the lifespan. Better understanding the risks and benefits associated with each of these controversial areas in cancer risk communication are crucial to optimizing adherence to recommended breast cancer risk management strategies and ensuring psycho-social well-being in the clinical delivery of genetic services for breast cancer susceptibility.

- Abstract
Objective: To examine the experience, comprehension and perceptions of learning of a parent's BRCA mutation during adolescence and early adulthood, and explore the impact on offspring's physical and psychosocial well-being., Methods: Semi-structured interviews were completed with 22 adult offspring who learned of their parent's BRCA mutation prior to age 25 years. Data were summarized using qualitative methods and response proportions., Results: Offspring reports of the content shared varied; discussion of cancer risks and offspring genetic testing were described more frequently than risk modification strategies. The majority of offspring reported a good understanding of the information shared and no negative aspects for learning this information. Some offspring reported changing their health behaviors after learning of the familial mutation; many tobacco users stopped smoking. Offspring interest in genetic counseling surrounding parent disclosure and genetic testing during adulthood were high., Conclusions: Some offspring understand and respond adaptively to early communication of a genetic risk for cancer, and disclosure may foster improved health behaviors during adolescence and young adulthood. Further research is necessary to evaluate how offspring conceptualize and utilize genetic risk and to identify the biopsychosocial factors predictive of adaptive/maladaptive responses to early disclosure of hereditary risk for adult cancer., ((c) 2008 John Wiley & Sons, Ltd.)
