T-cell mixed chimerism after allogeneic hematopoietic stem cell transplantation does not correlate with relapse in patients with acute myeloid leukemia

Key Points

• T-cell mixed chimerism does not influence relapse rates in patients with acute myeloid leukemia, indicating a need for alternative monitoring strategies.
• The study observed patients over time to track T-cell chimerism levels and incidence of leukemia relapse, emphasizing its clinical importance.
• Analysis of chimerism included various post-transplant time points to assess leukemia progression in a broader patient population.
• These findings may highlight the necessity for assessing other biomarkers beyond T-cell chimerism for predicting relapse in acute myeloid leukemia.
