Dorothy Teegarden, Ph.D. Oncological Sciences Center Lead, Cancer Prevention and Control Program Department of Foods and Nutrition Cancer Care Engineering: The Cancer Prevention Perspective
Cancer Prevention Impact • Diet • 30% of cancer deaths are related to diet (Doll, 1981). • Tobacco use • 30% or 170,000 cancer deaths in the United States in 2006 (ACS, 2006). • Other modifiable factors • Environmental exposures • Obesity • Lack of physical activity. • Could achieve by 2015 (IoM, 2004): • 19% decline in new cancer cases • 29% decline in the rate of cancer deaths

A Systems Approach to the Prevention & Treatment of Cancer Cancer Care Engineering
Cancer Care Engineering Goals Cancer Prevention and Chemoprevention We want to know who will develop specific cancers (environment/gene interactions) and what strategies will prevent the development of that cancer.
Cancer Prevention & Chemoprevention • Cancer Prevention by Dietary Agents • Nutrient and botanical • Chemoprevention • Very early detection • Biomarkers and imaging • Identification of risk factors • Behavioral modification/Public Policy approaches to reduce risk • Smoking cessation • Reducing incidence of obesity • Application of knowledge in healthcare settings
Treat Cancer and Cancer Prevention as a System • Interdisciplinary Team Approach • Enabling Systems Infrastructure • Data Integration • Patient Data, Literature Data, HSR Data • Rapid Communication • Efficient clinical validation • Hypothesis generation • Community-based Approach

Oxidative stress Balance oxidant>antioxidants Damage (proteins, lipid and nucleic acids) Cancer Factors that Impact Oxidative Stress Overproduction of reactive oxygen species Faulty or inadequate enzymatic antioxidant defenses Inadequate intake of antioxidants Faulty or inadequate DNA repair Association with genetic variants Vitamin D Status Colon cancer prevention Inhibits proliferation, induces differentiation, stimulates apoptosis Genetic variants associated with colon cancer progression Promote enhanced oxidative defenses Oxidative Stress, Vitamin D and Colon Cancer
Colon Cancer Susceptibility: Role of Oxidative Stress (and Vitamin D) Chemoprevention strategies involving both antioxidant and vitamin D supplementation may be useful for preventing colon carcinogenesis. Hypothesis The formation and progression of preneoplastic colon lesions (or a subset thereof) is dependent on the induction of oxidative stress and damage that is due in part, to genetic susceptibility factors and/or dietary and lifestyle factors that influence oxidative stress status.
