En Cheng, MD, PhD, is a Research Fellow at the Kaiser Permanente Northern California Division of Research. He is dedicated to promoting the adoption and integration of cancer research findings into everyday practice and public health settings to improve the health and healthcare of the population. His research focuses on long-term survival and causes of death after cancer diagnosis; health outcomes among young cancer populations; the development of novel prediction models for individualized survival after cancer diagnosis; the effects of diet, lifestyle, energy balance, and body composition on cancer risk, survival, and treatment-related complications; and disparities in healthcare and health outcomes among cancer survivors.

Dr. Cheng received his MD from Peking University and earned his PhD in epidemiology at Yale University. He also holds an MSPH in epidemiology from Emory University.

    Develop and Validate Novel Body Composition Scores to Predict Survival in Breast Cancer Patients

    Researchers have typically investigated how each body compartment may be individually associated with poor survival and other cancer outcomes. This ignores synergistic effects of adipose tissue and muscle on inflammation, oxidative stress, insulin resistance, and chemotherapy dosing, which collectively influence cancer prognosis. We aim to develop and validate novel composite scores of body compositions to predict breast cancer survival.

    Assess Inflammatory Potential of Diet Among Breast Cancer Patients: Novel Index and Short-Form Questionnaire

    Inflammation impacts cancer progression via stimulating tumor proliferation, migration, and angiogenesis. As a key regulator of inflammation, post-diagnosis diet strongly influences risk of breast cancer recurrence and mortality. We propose to develop an inflammatory dietary index for breast cancer patients that predicts canonical plasma inflammatory biomarkers. We will also design a brief inflammatory dietary questionnaire as a feasible dietary screener for clinical use.
