Abstract

The prognostic relevance of CRLF2 -rearrangements in childhood acute B-cell precursor lymphoblastic leukaemia (ALL), was assessed by a comparative analysis of 114 non-Down-syndrome patients (99 P2RY8-CRLF2+, 15 IGH@-CRLF2+), 76 from the AIEOP-BFM ALL 2000 and 38 from the MRC ALL97 trials. The 6-year cumulative relapse incidence of P2RY8-CRLF2+ patients treated on the two trials was not statistically different: 0·37 ± 0·06 vs. 0·25 ± 0·08 (P = 0·194). In contrast, 0/9 IGH@-CRLF2+ AIEOP-BFM, but 5/6 ALL97 patients relapsed. Conclusively, P2RY8-CRLF2+ patients had an intermediate protocol-independent outcome while the different prognosis of IGH@-CRLF2+ patients could be related to the different structures of the applied treatment protocols.
