On 8/7/09 my daughter, Courtney was dx with Pre-B ALL at age 13. As of 1/2010, she became weak and lost her ability to walk,she received vincristine that was stopped and continued with 6mp and MTX, she has been wheelchair bound since then. During her treatment we found out that she could not tolerate the full dose of her chemo treatment, genetic test was positive. Courtney had a very rough 2 1/2 years with her treatment, if it could happen it did to her. On 12/22/11 she finished her treatment and is cancer free! So very grateful for that! Courtney is in physical therapy 3 times a week and able to take steps and short walks with a walker. I would like to know if anyone else is or has gone through this? I have many questions. The doctors have not dealt with this and we feel lost. Any advice will greatly be appreciated.
