Clinical features and prognostic significance of TCF3-PBX1 fusion gene in Chinese children with acute lymphoblastic leukemia by using a modified ALL-BFM-95 protocol..     ///    " For children with precursor B (pre-B) acute lymphoblastic leukemia (ALL) with TCF3-PBX1 fusion gene, their prognosis has been a controversial topic. "    ///    "Clinical characteristics of 20 patients with TCF3-PBX1 fusion gene were analyzed retrospectively, which were classified to the intermediate-risk (IR) group according to Chinese Children Leukemia Group-2008 (CCLG-2008) risk-stratification criteria and protocol based on the backbone of BFM 95 trails. "    ///    "When intensive chemotherapy was used, the TCF3-PBX1 was associated with a favorable outcome in childhood pre-B ALL. "    ///    There were not cases with CNS relapse in the TCF3-PBX1 group.     ///    "The 5-year probability of event-free survival (EFS) rates were 84.4 ?? 15.6% and 73.5 ?? 15.6% in the TCF3-PBX1 group and the comparison group (P = .35), respectively. "    ///    Eighty five cases without TCF3-PBX1 in the same IR group were regarded as the comparison group.
