We aimed to identify relapse predictors in children with a B-cell precursor acute lymphoblastic leukemia (ALL) and an intrachromosomal amplification of chromosome 21 (iAMP21), a novel genetic entity associated with poor outcome. ⋯ The overall and early relapse rates in the BFM study were lower than that in a previous United Kingdom Medical Research Council/Childhood Leukemia Working Party study (38% v 61% and 27% v 47%, respectively), which might result from more intensive induction and early reintensification therapy in the ALL-BFM protocols. MRD values were the only reliable parameter to discriminate between a low and high risk of relapse (P = .02).

Randomized Controlled Trial Multicenter Study
Efficacy and safety of lapatinib as first-line therapy for ErbB2-amplified locally advanced or metastatic breast cancer.
This study (EGF20009) assessed the efficacy and tolerability of two lapatinib administration schedules as first-line monotherapy in women with ErbB2-amplified locally advanced or metastatic breast cancer. ⋯ Lapatinib demonstrated clinical activity and was well tolerated as first-line therapy in ErbB2-amplified locally advanced or metastatic breast cancer. This study supports further evaluation of lapatinib in first-line and early-stage ErbB2-overexpressing breast cancer.
