ABSTRACT

OBJECTIVE:

To investigate the clinical features, treatment and prognosis of children with SIL-TAL1 fusion gene positive T-cell acute lymphoblastic leukemia (T-ALL).

METHODS:

The data of 101 children with T-ALL were collected from April 2005 to November 2012 in Beijing Children's Hospital. The common clinical features, early treatment response, minimal residual disease (MRD), event-free survival (EFS) and relapse-free survival (RFS) were compared between children with SIL-TAL1 positive and negative T-ALL. The treatment efficacy in children with SIL-TAL1 positive T-ALL was compared between BCH-2003 and CCLG-2008 protocol.

RESULTS:

Out of 101 cases, 22 cases (21.9%) of T-ALL carried SIL-TAL1 fusion gene. The distribution of sex, age, response to prednisone and central nervous system (CNS) involvement were no significant different at diagnosis between SIL-TAL1 positive and negetive patients. However, the WBC count in SIL-TAL1 positive cases were significantly higher than that of SIL-TAL1 negative cases at diagnosis (P<0.05). Additionally, MRD levels were not significantly different between children with SIL-TAL1 positive or negative T-ALL at 3 time points including after the remission induction therapy, before delayed intensive therapy II and before maintenance therapy. However, the number of cases with high MRD levels before consolidation therapy were more in SIL-TAL1 positive group than that in SIL-TAL1 negative group (P<0.05). The cases with high MRD levels before delayed intensive therapy I was more in SIL-TAL1 negative group than that in the SIL-TAL1 positive group (P>0.05). Besides, there were no significant differences in 5-year EFS and RFS between the two groups. The risk of 22 children with SIL-TAL1 positive acute T-ALL was again stratified according to the typing stemdard in CCLG-2008 protocol, as a result, the risk in BCH-2003 group (10 cases) was significantly higher than that in BCH-2008 group (12 cases) (P<0.05), but no significant difference was found in common clinical features, early treatment response, MRD levels and treatment efficacy.

CONCLUSIONS:

Although WBC level was significantly higher in SIL-TAL1 positive group than that in SIL-TAL1 negative group, the treatment efficacy in SIL-TAL1 positive group was similar to SIL-TAL1 negative group. Meanwhile, the children with SIL-TAL1+ T-ALL may respond poorly to early intensive therapy, the BCH-2003 protocol may be more suitable for the patients with this subtype of leukemia.
