Speaker: John Pierce, Ph.D., University of California, San Diego Medical Center focusing in Cancer/Family & Preventive Medicine. He has published more than 260 papers in the areas of cancer prevention and control.

Synopsis: Dr. Pierce will present the results of his Women's Healthy Eating & Living (WHEL) study on the role of a plant-based diet in breast cancer progression.

Intended Audience: Internists, oncologists, registered dieticians, registered nurses, and cancer researchers.

Objectives: Upon completion of attending this presentation, participants should be able to:

  • Provide a detailed understanding of the methodology of the WHEL (Women’s Healthy Eating & Living) randomized trial.
  • Present and discuss the evidence for the degree of dietary change achieved by subgroups of the WHEL population.
  • Present and discuss the evidence that the dietary change achieved was associated with health outcomes among early stage breast cancer survivors.

John P. Pierce, Ph.D.John P. Pierce, Ph.D., is the Sam M. Walton Professor for Cancer Research and is director of population science at the Moores University of California, San Diego, Cancer Center. Dr. Pierce is broadly trained with degrees in physiology/pharmacology, epidemiology and biostatistics, and psychology, and he has a doctorate in communication research.

Dr. Pierce is a fellow of the American College of Epidemiology as well as the Society for Behavioral Medicine. He has published more than 270 papers in the areas of cancer prevention and control. His research group has become well known for its studies of health behavior related to cancer, with a particular emphasis on measurement in both the dietary and tobacco fields. In the 1990s, his research group developed lay lifestyle coaching over the telephone. This approach has been demonstrated to be successful for both smoking cessation and for promoting a major change in dietary pattern.

Dr. Pierce has been the principal investigator on the Women’s Healthy Eating and Living randomized trial of the effect of a plant-based dietary pattern on breast cancer prognosis. This study of more than 3,000 breast cancer survivors has reported on the main study results after 7.3 years of follow-up. Subpopulation data are currently being reported.
