• Clinical Trial Participation:
  • Enrolled in a clinical trial for a new targeted therapy, such as a novel FLT3 inhibitor, which showed promise in treating resistant AML.
• Stem Cell Transplant:
  • Following successful response to salvage therapy and clinical trial treatment, underwent an allogeneic stem cell transplant to achieve long-term remission.

1.3.4 Outcome and Results

• Survival Rate:
  • Achieved complete remission with no evidence of residual disease following stem cell transplant.
• Long-Term Results:
  • Stable remission and good quality of life post-transplant, with ongoing surveillance to monitor for relapse.
