Epidemiologist Erin Bowles is looking at cancer and aging from many different perspectives. Her research brings new insight into breast cancer risk factors and treatment, while also helping improve cancer care for patients and families.
As a key member of two large cancer collaborations—the National Cancer Institute (NCI)'s Breast Cancer Surveillance Consortium and the HMO Cancer Research Network (CRN)—Ms.Bowles has developed diverse expertise that includes reading mammograms for breast density and doing statistical analyses. Her past work with Group Health Research Institute (GHRI) investigators Diana Buist, PhD, and Diana Miglioretti, PhD, confirmed that breast density is a key breast cancer risk factor. Her work with Ed Wagner, MD, MPH, resulted in a key publication showing that certain breast cancer treatments increase the risk of heart failure beyond what had been shown in clinical trials. Ms. Bowles is also passionate about doing research to help improve the quality of cancer care. She and CRN colleagues were funded through an NCI challenge grant to develop a national breast cancer surgical quality database and evaluate variation in surgical margins across facilities and providers.
Ms. Bowles' experience working with large cancer cohorts has provided her with expertise in data collection and management. She has worked with natural language processing programmers to successfully obtain findings from breast pathology and radiology reports. She has worked extensively with administrative data and published several papers on the validity of using health plan data for cancer treatment research. Recently she joined the Adult Changes in Thought study team, and is overseeing their large data repository and data sharing for aging research. She is especially interested in enhancing the efficiency of data collection on these large projects, which has been increasingly important in an era of limited funding.
