My four year old daughter underwent her first round of ch14.18 and became neutropenic a few days after her treatment ended. Her WBC went from 7.1 to 1.5 overnight with her polys at 0.45. Just wondering if anyone has had a similar experince since the doctors at our hospital have never seen this happen. She is due to start her next cycle in a week and her polys are only 0.6. She has also needed a red blood cell and platelet transfusion which again the hospital says should not happen. Just wanted to know if anyone else has had to happen.
