Interview Session One:
Segment 01 (Overview)
An Introduction to Clinical Genetics and Cancer and Isolating Hereditary Components (listen/read)
Louise C. Strong, MD begins by giving a brief overview of the topics she will discuss. Her presentation will focus on genetic variation and how this relates to cancer including hereditary tumors, conditions which predispose to cancer, and environmental factors. She explains how she will talk about several different types of cancer a why they provide unique information and data for research and studying the how’s and whys of cancer such as why people with certain preexisting disorders or conditions have higher instances of certain kinds of cancer. She talks about how looking at the rarer cancers can provide insight into genetic factors in cancer and allow heredity fractions to be isolated and identified.
Segment 02 (Overview)
Conditions Which Predispose To Cancer and What They Can Teach Us (listen/read)
Dr. Strong discusses conditions which predispose people to cancer and subgroups who experience higher rates of cancer such as chromosomal instability conditions such as Downs Syndrome. She then discusses skin cancer ideology and which conditions predispose to skin cancer such as single gene disorders, polygenic disorders, and environmental conditions, and talks about what we can learn from this.
Segment 03 (Overview)
Types of Genetic Studies (listen/read)
Dr. Strong discusses the different types of genetic studies including family studies, twin studies, linkage studies, association studies, immuno-competence studies, and in vitro studies. She explains how these studies are performed and why. In, addition, she also provides examples, and explains what was learned for each example.
Segment 04 (Overview)
Hereditary Breast Cancer Tumors (listen/read)
Dr. Strong discusses hereditary tumors including the importance of studying them and their characteristics such as family history, early age at onset, and multiple primary tumors. She uses hereditary Breast Cancer Tumors as an example. Next, Dr. Strong discusses how genetic studies can allow those at risk to be defined and identified as high risk for hereditary cancer which makes screening much more important. Then she talks about identifying and describing particular cancer syndromes related to a specific gene defect.
Segment 05 (Overview)
Prospective Family Study Including Twin Studies (listen/read)
Dr. Strong discusses what a prospective family study is, what can be learned from it, and why it is significant regarding cancer research. She explains these studies can help solve specific single gene defects, and provides an example of childhood tumors of retinoblastoma. Next. Dr. Strong describes what was known before the study as well as what was learned from the study, as well as the specifics such as the laterality of the tumors. Dr. Strong then talks about prospective twin studies including what they can teach us about cancer, and the difficulties involved in conducting twin studies, and provides examples of successful and useful twin studies explaining why they are valuable.
Segment 06 (Overview)
Linkage and Association Studies (listen/read)
Dr. Strong clarifies some common misconceptions about linkage studies, and discusses some of the difficulties and challenges involved in linkage studies. Next, Dr. Strong talks about what can be learned from linkage studies and why they are important. Dr. Strong then describes association studies including why they are important and what they can teach us. In addition, Dr. Strong explains important aspects and terminology regarding association studies including genetic markers, chromosomal markers, histocompatibility antigens, clinical markers, and tissue susceptibility studies, and provides examples.
