Relationship Between Perceived COVID-19 Risk and Change in Perceived Breast Cancer Risk: Prospective Observational Study.

Background: Whether COVID-19 is associated with a change in risk perception about other health conditions is unknown. Because COVID-19 occurred during a breast cancer study, we evaluated the effect of COVID-19 risk perception on women's breast cancer risk perception.

Objective: This study aims to evaluate the relationship between perceived risk of COVID-19 and change in perceived breast cancer risk.

Receiving a Pathogenic Variant in a Population Breast Cancer Screening Trial: A Mixed Method Study.

Introduction: Risk-based breast cancer screening aims to address persistent high morbidity and mortality. This study examined the experience of participants in the Women Informed to Screen Depending on Measures of Risk (WISDOM) trial who received a pathogenic variant in one of nine high or moderate penetrance breast cancer genes.

Methods: Participants completed a brief survey (n = 181) immediately following the results disclosure and 1 year later.

Elevated risk thresholds predict endocrine risk-reducing medication use in the Athena screening registry.

Risk-reducing endocrine therapy use, though the benefit is validated, is extremely low. The FDA has approved tamoxifen and raloxifene for a 5-year Breast Cancer Risk Assessment Tool (BCRAT) risk ≥ 1.67%.

A novel clinical trial recruitment strategy for women's cancer.

Objective: To address a deficiency in clinical trial and research enrollment in gynecologic cancer studies, we launched a paper based patient research registry. To improve registry enrollment, we transitioned to an online registry and trial matching mechanism to aid women in accessing open studies.

Methods: Utilizing a validated verification platform, we designed a web-based registry and trial matching mechanism for women over age 18.

IGF-I and IGFBP-3 polymorphisms and risk of prostate cancer.

Background: Insulin-like growth factor-I (IGF-I) is a potent mitogen for both normal and malignant prostate epithelial cells. The majority of circulating IGF-I is bound in a complex with IGF binding protein-3 (IGFBP-3), which in turn limits IGF-I bioavailability. Multiple studies suggest that higher IGF-I and/or lower IGFBP-3 serum levels are positively associated with prostate cancer risk.

An integrated 4249 marker FISH/RH map of the canine genome.

Background: The 156 breeds of dog recognized by the American Kennel Club offer a unique opportunity to map genes important in genetic variation. Each breed features a defining constellation of morphological and behavioral traits, often generated by deliberate crossing of closely related individuals, leading to a high rate of genetic disease in many breeds. Understanding the genetic basis of both phenotypic variation and disease susceptibility in the dog provides new ways in which to dissect the genetics of human health and biology.

BRCA1 and BRCA2 mutations in women from Shanghai China.

Little is known about the frequency of germ-line mutations in the breast cancer susceptibility genes BRCA1 and BRCA2 among Asian populations. We investigated the distribution of BRCA1 and BRCA2 germ-line mutations and polymorphisms in a cohort of women from Shanghai, China. Study subjects totaled 1306, and included 645 women with breast cancer, 342 women with benign breast disease, and 319 unaffected controls, born between 1924 and 1958, selected from women enrolled in a randomized trial of Breast Self-Examination in Shanghai, China.

Association of HPC2/ELAC2 polymorphisms with risk of prostate cancer in a population-based study.

Genetic polymorphism in HPC2/ELAC2 was recently associated with risk of sporadic prostate cancer. To determine the contribution of two HPC2/ELAC2 missense variants (Ser217Leu and Ala541Thr) to the risk of developing prostate cancer, we conducted a population-based case-control study of middle-aged men (40-64 years). Cases (n=591) were ascertained from the Seattle-Puget Sound Surveillance, Epidemiology, and End Results Cancer Registry and Controls (n=538) from the same general population were identified through random-digit dialing.
