Hereditary Breast and Ovarian Cancer Genetic Risk: Screening and Treatment Among Transgender and Gender Diverse Patients.

IntroductionTransgender and gender diverse (TGD) populations with hereditary cancer syndromes face unique barriers to care and thus may not be accessing appropriate cancer screening or risk-reducing procedures. Our objective was to evaluate health care utilization of TGD patients with hereditary cancer syndromes. This includes counseling received, cancer screenings conducted, and risk-reducing procedures performed. MethodsA case series of TGD patients (N = 11) with hereditary breast and ovarian cancer (n = 9) or Lynch syndrome (n = 2) who received care within Kaiser Permanente Northern California between 2009 and 2019. ResultsAll patients received counseling and prophylactic options. Three patients (27%) completed all recommended screening, 6 (54%) had partial screening, 1 (9%) received no screening, and 1 (9%) did not require any screening. Six (55%) underwent a risk-reducing procedure. DiscussionThis case series highlights that despite all the study participants being appropriately counseled by practitioners about their risk of cancer, screening, and prophylactic options, in many cases, the screening received was partial or absent. Relatively few completed all the recommended screenings based on their clinical risk factors. ConclusionMany of the TGD patients with hereditary cancer syndromes in this cohort did not complete all the recommended cancer screening. This can be an area of focus in order to improve the quality of care provided to this vulnerable population.
