## Abstract

PROJECT SUMMARY/ABSTRACT
The purpose of this K01 career development award submission is to support a period of didactic training and
mentored research for Dr. Traci Bethea, Assistant Professor at Boston University School of Medicine, to
increase her ability to carry out studies of cancer survivorship and to become an independent cancer
researcher. Dr. Bethea’s long-term goal is to carry out studies that will result in a better understanding of
factors that influence cancer survivorship and that will lead, ultimately, to higher survival among Black women
affected by breast cancer and reduced cancer health disparities. She has already had training in environmental
health and cancer epidemiology. Through the K01 training, she will develop expertise in cancer survivorship,
statistical analyses of survival data, and molecular epidemiology, under the mentorship of a distinguished
panel of researchers – Drs. Julie Palmer, Christine Ambrosone, Nancy Keating, Michael LaValley, and Edward
Ruiz-Narváez. The mortality rate from breast cancer, the most commonly occurring cancer among women in
the U.S., is 42% higher in Black women than White women. Dr. Bethea’s research will address an
understudied topic, modifiable factors related to breast cancer survivorship in Black women. To this end, her
proposed research utilizes data from the Black Women’s Health Study (BWHS), a longitudinal study of 59,000
African American women. During follow-up, more than 2,300 incident invasive breast cancer cases have
occurred and they will be the subject of Dr. Bethea’s research. Dr. Bethea will assess several modifiable risk
factors – post-diagnosis use of aspirin and other nonsteroidal anti-inflammatory drugs (NSAIDs), and post-
diagnosis use of vitamin D supplements and of predicted plasma vitamin D levels – in relation to breast cancer
recurrence and breast cancer-specific mortality among breast cancer cases in the BWHS. She will create
genetic risk scores using data on single nucleotide polymorphisms (SNPs) from candidate genes and will
assess whether the associations of aspirin/other NSAIDs or of vitamin D supplementation and predicted
plasma vitamin D levels with breast cancer recurrence and breast cancer-specific mortality are modified by
genetic risk scores. Thus, Dr. Bethea will create a specific area of research in which she is highly proficient. As
an independent researcher, it is anticipated that she will lead further BWHS research on cancer survivorship,
which could be stand-alone studies or collaborative studies with other investigators. Dr. Bethea is an
outstanding candidate. A K01 career development award will enable her to conduct important research as an
independent investigator and put her on the path to obtaining NIH R01 and similar grant support and on a path
to promotion. Importantly, it will also provide valuable information on factors related to breast cancer survival in
Black women.
