Collaborative webinar presented by Oncoendocrinology SIG and Transgender Research & Medicine SIG  

Date: January 4, 2024 
Time: 12:00 to 1:30 PM ET 

Moderator: Ole-Petter R. Hamnvik, MB, BCh, BAO 
Case Presenters: Tugce Akcan, MD; and Ling Zhu, MB, BChir   
Expert Discussants: Ann Partridge, MD, MPH; Alexi Wright, MD, MPH; and Koen M. A. Dreijerink, MD, PhD

Description: As increasing numbers of transgender and gender diverse patients are seeking gender-affirming hormone treatment, more patients are needing to balance the risks and benefits of such treatment in the setting of known or newly diagnosed sex hormone-sensitive cancers (for example breast cancer and cancers of the reproductive tract). In this webinar, experts in oncology and gender-affirming care are discussing two clinical cases, providing their insights in the considerations that need to be made. 

Learning Objectives: 

  1. Appraise current data on cancer risk with gender-affirming hormone therapy.
  2. Summarize therapeutic approaches for gender affirmation in transgender patients who are diagnosed with sex-hormone sensitive cancers.
  3. Contrast post-cancer diagnosis sex hormone management in cisgender people from management in transgender and gender diverse people.
