Understanding Your Options

Deciding whether to pursue a stem cell transplant is deeply personal and often complex. This is especially true for a preemptive transplant which is to have the procedure done before a blood cancer. Patients are encouraged to fully understand these considerations and engage in shared decision-making with their medical team before reaching a final decision. The information on this page is here to help you prepare for that conversation.

Your options:

You may be considering one of two main approaches:

• Move forward with a preemptive stem cell transplant
• Continue close monitoring without transplant at this time

This reflection tool was created specifically for individuals with RUNX1-FPD who are considering these options.
