Kaiser Permanente Researcher Profiles


 
Marilyn L. Kwan, PhD, is a Research Scientist III (equivalent to Professor academic rank) at the Division of Research, Kaiser Permanente Northern California. She graduated from University of California, Berkeley, with her PhD in Epidemiology in May 2004 and completed a one-year postdoctoral fellowship in September 2005, also at UC Berkeley. Dr. Kwan joined the Division of Research in July 2005, where her current research focus is breast and bladder cancer prognosis and survival. Specifically, her interests include lifestyle and molecular factors and their associations with cancer recurrence, survival, and quality of life. She also studies the long-term health effects of cancer treatment specifically lymphedema, fractures, and cardiovascular disease, in breast cancer survivors. Dr. Kwan’s research has been funded by the National Cancer Institute, American Cancer Society, and California Breast Cancer Research Program.

Predictors of CVD among Breast Cancer Survivors in an Integrated Health System

This study will comprehensively examine clinical and behavioral predictors of cardiovascular disease (CVD) outcomes among breast cancer survivors, and will maximize unique patient and data resources available at Kaiser Permanente Northern California (KPNC). We will compare CVD events in the Pathways Study, a cohort of female KPNC members age ≥21 years diagnosed with invasive breast cancer (n=4,453, R01CA105274) with CVD events in a new age, race/ethnicity, history of comorbidity, and length of KPNC membership matched cohort of healthy KPNC female members (n=22,265). Results from this study will have important implications for identifying breast cancer subgroups at high risk of CVD and identifying potential targets for intervention, such as medication adherence and control of CVD risk factors.

Impact of Low IL-10 Levels at Birth and Leukemia Risk

The objectives of this retrospective cohort study of an established case-control study of childhood leukemia are to understand the relationships among immune status at birth, infectious exposures during childhood, and leukemogenesis, and to use this understanding to decrease the incidence of childhood acute lymphoblastic leukemia (ALL). The aims are to: 1) Assess whether a low interleukin-10 level at birth is associated with an increased incidence of early infections characterized by severe clinical symptoms from medical records and self-report; and 2) Determine whether decreased interleukin-10 can contribute to increased ALL in the setting of immune system activation.

Risk of Pediatric and Adolescent Cancer Associated with Medical Imaging

The aims of this multiple PI grant are to: 1) Evaluate patterns of medical imaging (utilization and radiation dose) and estimate cumulative exposure to ionizing radiation from medical imaging in a) children (0-18 years old) and b) pregnant women, from 1996-2016; 2) Determine the risk of childhood leukemia among children and adolescents following exposure to all medical imaging examinations that deliver ionizing radiation from 1996-2016 and followed through 2017. We will also examine effects due to exposure from CT exams alone; 3) Determine the risk of childhood cancers among children and adolescents following fetal, in utero (maternal pregnancy) exposure to medical imaging from 1996-2016 followed through 2017; 4) In the subset of the population with complete information during in utero and child or adolescent exposure to medical imaging, assess the cumulative impact of these exposures on childhood cancers.

Diet and Lifestyle in a Prospective Study of Bladder Cancer Survivors

This study involves a new prospective cohort of more than 1,800 non-muscle invasive bladder cancer cases to investigate the role of cruciferous vegetable intake, along with associated individual genetic profiles, on reducing recurrence and progression of disease and improving the efficacy of current treatment modalities.

Lifestyle and Molecular Factors of Bone Health in Breast Cancer Survivors

This project will investigate the impact of modifiable lifestyle factors, germline genetic variations, and serum biomarkers, on adverse skeletal outcomes among aromatase inhibitor users, as well as develop a prediction model for risk of fractures for postmenopausal breast cancer patients taking aromatase inhibitors.

Urinary Diversion Among Bladder Cancer Survivors: Cost, Complications and QOL

This mixed-method, comparative effectiveness study will compare costs, complications, patient- and family-centered outcomes related to urinary diversion. Study participants will include bladder cancer patients undergoing cystectomy and their family caregivers within three Kaiser Permanente regions with a membership base of over six million enrollees.
