In search of the original leukemic clone in chronic myeloid leukemia patients in complete molecular remission after stem cell transplantation or imatinib

It is not clear if absence of BCR-ABL transcripts—complete molecular response (CMR)—is
synonymous with, or required for, cure of chronic myeloid leukemia (CML). Some patients
achieve CMR with imatinib (IM), but most relapse shortly after treatment discontinuation.
Furthermore, most patients in long-term remission (LTR) post–stem cell transplantation
(SCT) are considered functionally cured, although some remain occasionally positive for low-
level BCR-ABL mRNA. Interpretation of the latter is complicated because it has been …

Existe uma forte associação causal entre o gene de fusão BCR-ABL e a leucemia mielóide
crónica (LMC). Daí o interesse na compreensão da origem do rearranjo BCRABL, assim
como na utilização do BCR-ABL para medir doença residual em doentes com LMC. Uma
proporção relevante dos indivíduos saudáveis tem ARNm de BCR-ABL no sangue
periférico. Este facto levanta questões relativas 1) ao desenvolvimento da LMC; e 2) ao
significado da ocorrência de níveis baixos de transcritos de BCR-ABL no sangue periférico …
