PROJECT SUMMARY/ABSTRACT
Transgender and gender diverse (TGD) individuals comprise a growing population of over 1.3 million
people in the United States. TGD individuals experience cancer care-related disparities with
comparatively more frequent late-stage cancer diagnoses and more premature cancer deaths. Although
cancer screening mammography saves lives, previous, relatively small studies suggest TGD individuals
who are eligible for screening are not screened. Further, TGD people generally remain inaccessible to
research because of fear of discrimination. This K23 career development application seeks to learn how
many of these screening-eligible individuals are not screened for breast cancer and why. In aim 1, we
propose to acquire the necessary – but unknown -- benchmark data on the actual rates of cancer
screening mammography in TGD individuals who should be screened and to identify factors associated
with screening or lack thereof. We propose to interrogate and analyze data from a 200 million-patient
insurance claims database (the national Optum Labs Data Warehouse). To identify TGD patients, we will
use surgical, pharmacy, and outpatient visit coding information (our preliminary data demonstrate access
to 13,561 eligible TGD individuals). We will report cancer screening mammography rates in these TGD
individuals and compare these rates to those in cisgender women. This first aim promises to provide the
most robust data to date on cancer screening mammography in TGD individuals and will be crucial in
planning future studies to improve screening rates in this population. In aim 2, the principal investigator
(PI) will undertake qualitative interviews of TGD individuals who are 40+ years of age (40 years is the
age when screening mammography typically starts) to understand these individuals’ thoughts on
screening mammography (and on other cancer screening). These in-depth interviews will allow us to
learn directly from these underserved individuals how life-saving cancer screening procedures can be
made more accessible and will enable the PI to forge trust among TGD individuals. These 2 aims – in
conjunction with the completion of relevant coursework and ongoing interactions with a multidisciplinary
team of senior mentors (an endocrinologist, who directs the Mayo Clinic Transgender and Intersex
Specialty Care Clinic; a medical oncologist, who is interested in healthcare disparities among older
sexual and gender minority patients; a statistician; a qualitative researcher; a primary care physician with
expertise in the effects of hormones on disease outcomes; and an epidemiologist who focuses on
screening mammography) -- will enable the PI, a medical oncologist, to develop the necessary skills to
emerge as a national leader in cancer care of TGD individuals. The ultimate goal of this research is to
help underserved TGD individuals receive the same lifesaving benefits of cancer screening as the
general population.
