PG - 194-7 AB - BACKGROUND AND OBJECTIVE: Interphase fluorescence in situ hybridization (FISH) and real-time quantitative reverse transcription PCR (RQ-PCR) are the common methods for monitoring minimal residual disease (MRD) in chronic myeloid leukemia (CML) patients. This study was to assess the value of monitoring BCR-ABL fusion gene level in CML patients after allogeneic hematopoietic stem cell transplantation (allo-HSCT) using FISH and RQ-PCR. METHODS: BCR-ABL fusion gene levels were detected in the bone marrow of 31 patients with CML before and 3-48 months after allo-HSCT using FISH and RQ-PCR. RESULTS: BCR-ABL positive cells detected by FISH were decreased 3-30 months after allo-HSCT and BCR-ABL/ABL mRNA was reduced by 2 logarithmic units in RQ-PCR (P < 0.05). While no BCR-ABL positive cell was detected by FISH 30 months after allo-HSCT, BCR-ABL/ABL mRNA was detected by RQ-PCR and declined by more than 3 logarithmic units, (P < 0.05). CONCLUSIONS: Dynamic monitoring of BCR-ABL gene on molecular level in CML patients after allo-HSCT is useful in the early prediction of susceptibility to recurrence in the patients and in designing intervention, and is thus helpful in improving the overall survival rate after transplantation.
