Real-time quantitative reverse transcription polymerase chain reaction (RT-qPCR)-based detection of abnormal fusion transcripts is an important strategy for the diagnosis and monitoring of patients with acute myeloid leukemia (AML) with t(8;21)(q22;q22); RUNX1-RUNX1T1, inv(16)(p13.1;q22); CBFB-MYH11 or t(15;17)(q22;q12); PML-RARA.
In this study, CD10-negative infant ALL with MLL/AF4, CD10-positive infant ALL with germline MLL, CD10-positive pre-B ALL cell line, infant acute myeloid leukemia (AML; M5) with MLL/AF9 and pediatric AML (M2) with AML1/ETO were analyzed for VDJH status and methylation of CD10 gene promoters.
We performed this study to investigate the incidence of AML1/ETO rearrangement in adult acute myelogenous leukemia (AML), especially in M2 subtype, to make a comparison of clinical, morphological and immunophenotypic characteristics between AML1/ETO rearrangement positive and negative group in patients with AML and to analyze the correlation with other biological parameters.
