Hi, Joy.
Welcome to Marrowforums. As is always the case, we're sorry you have to be here because it means someone in your family is sick, but we hope we can help you feel less alone and more informed about what is happening with your father.
You're right that the conventional wisdom is that AML that arises from MDS is generally harder to cure, but that doesn't mean people aren't cured and it doesn't mean your father won't be. The chemo for AML can be very difficult, but your father's age is only one aspect of the situation. You say he was diagnosed about a year ago. What treatments, if any, did he receive for his MDS? How did he respond to those treatments? Is he in generally good health--apart from his AML?
I hope that any Marrowforums members we have who might be familiar with your situation will speak up. In the meantime, you should call the Aplastic Anemia & MDS International Foundation (800/747-2820) and ask to speak to someone in their
Global Volunteer Network who has experiences with an MDS-to-AML transition.
Where is your father being treated?
Hope this helps.
