It's generous of you to share your mother's story so that it can provide information to other patients.
I'm very sorry to hear that you lost her to bone marrow failure, especially because ATG might have helped her. Keeping her platelets up was obviously a major treatment challenge.
Do you know why the diagnosis was "probable MDS" at first, and later MDS? How did they decide on the diagnosis?
