Hereditary Breast and Ovarian Cancer

PROGECT is a registry for patients with Triple Negative breast cancer (TNBC) or patients who have an identified germline mutations (such as a mutation on the BRCA1 or BRCA2 genes).

NOTE: This is a research study and is not meant to be a substitute for clinical genetic testing. Families may never receive results from the study or may receive results many years from the time they enroll. If you are interested in clinical testing please consider seeing a local genetic counselor or other genetics professional. If you have already had clinical genetic testing and meet eligibility criteria for this study as shown in the Eligibility Section, you may enroll regardless of the results of your clinical genetic testing. While it is well recognized that hereditary factors contribute to the development of a subset of human cancers, the cause for many cancers remains unknown. The application of next generation sequencing (NGS) technologies has expanded knowledge in the field of hereditary cancer predisposition. Currently, more than 100 cancer predisposing genes have been identified, and it is now estimated that approximately 10% of all cancer patients have an underlying genetic predisposition. The purpose of this protocol is to identify novel cancer predisposing genes and/or genetic variants. For this study, the investigators will establish a Data Registry linked to a Repository of biological samples. Health information, blood samples and occasionally leftover tumor samples will be collected from individuals with familial cancer. The investigators will use NGS approaches to find changes in genes that may be important in the development of familial cancer. The information gained from this study may provide new and better ways to diagnose and care for people with hereditary cancer. PRIMARY OBJECTIVE: * Establish a registry of families with clustering of cancer in which clinical data are linked to a repository of cryopreserved blood cells, germline DNA, and tumor tissues from the proband and other family members. SECONDARY OBJECTIVE: * Identify novel cancer predisposing genes and/or genetic variants in families with clustering of cancer for which the underlying genetic basis is unknown.

Breast, colorectal, ovarian, and endometrial cancers constitute approximately 30% of newly diagnosed cancer cases in Switzerland and affect more than 12,000 individuals annually. Several hundred of these patients are likely to carry known genetic mutations associated with HBOC or LS. Genetic testing for hereditary susceptibility to cancer can prevent many cancer deaths through early identification and engagement in high-risk management care that involves intensive surveillance, chemoprevention and/or prophylactic surgery. However, current rates of genetic testing indicate that many Swiss mutation carriers and their family members do not use cancer genetic services (counseling and/or testing), either due to lack of coordination of care or due to lack of communication about the mutation among family members. Cascade screening identifies and tests family members of a known mutation carrier. It determines whether asymptomatic family members are carriers of the identified mutation and proposes management options to reduce harmful outcomes. Robust evidence of basic science and descriptive population-based studies in Switzerland support the necessity of cascade screening for HBOC and LS. However, translation of this knowledge into public health interventions is lacking. Specific Aims of the CASCADE study are: 1. Survey Index Patients diagnosed with HBOC or LS from clinic-based genetic testing records and determine their cancer status and surveillance practices; needs for coordination of medical care; psychosocial needs; patient-provider and patient-family communication needs; quality of life; willingness to serve as advocates for cancer genetic services for blood relatives. 2. Survey first- and second-degree relatives, and first cousins identified from pedigrees and/or family history records of HBOC and LS Index Patients and determine their cancer and mutation status; cancer surveillance practices; needs for coordination of medical care; barriers and facilitators to using cancer genetic services; psychosocial needs; patient-provider and patient-family communication needs; quality of life; willingness to participate in a study designed to increase use of cancer genetic services. 3. Explore the influence of patient-provider communication about genetic cancer risk on patient-family communication and the acceptability of a family-based communication, coping, and decision support intervention with focus group(s) of mutation carriers and blood relatives.

This is a mixed-methods Hybrid Type 1 research design (efficacy study) in which we aim to conduct a two-arm randomized controlled trial and an Implementation Focused Process Evaluation of a culturally-targeted video and referral screening tool. In this study, the investigators aim to evaluate the efficacy of a culturally targeted video previously developed by the research team vs. a Spanish-language fact sheet from an established group on enhancing genetic counseling and testing uptake and psychosocial outcomes in Latina women at risk for hereditary breast and ovarian cancer. The investigators will test the video's efficacy while also gathering data on the implementation and future sustainability of using the Risk Screening Tool (RST) and video in community clinics.
