ABSTRACT
The significance of clonal evolution in myelofibrosis (MF) relapse remains poorly understood. Here we performed panel sequencing in paired samples of 30 patients with MF who relapsed after undergoing allogeneic hematopoietic stem cell transplantation (alloSCT). We identified a median of 2 mutations (range, 0 to 12) in a median of 2 genes (range, 0 to 8) before allo-SCT, along with a median of 2 mutations (range, 0 to 12) in 2 genes (range, 0 to 6) at relapse. Additional whole-genome sequencing (n = 6) did not elucidate additional molecular changes. Taken together, our data provide further evidence, here on MF, that clonal evolution after alloSCT is limited and that instead, alloSCT selects specific (sub)clones.
