Bridge therapy" benefits children with high-risk neuroblastoma

No bridge therapy prior to consolidation therapy, bridge therapy prior to consolidation therapy, and additional post-induction therapy without consolidation therapy were the three groups. The investigators were interested in evaluating if the addition of bridge therapy prior to consolidation with stem cell transplant improved the event-free survival, or the time after treatment that cancer did not come back or get worse in patients with residual neuroblastoma at the end of induction therapy.

Among patients with stable cancer at metastatic sites after induction therapy, those who received bridge therapy had significantly improved event-free survival compared with those who directly underwent consolidation therapy.

Patients treated with post-induction therapy who did not receive consolidation therapy (group 3) experienced inferior event-free survival than patients in groups 1 or 2; however, those in group 3 with no signs of metastatic cancer following post-induction therapy had significantly better 3-year event-free survival than those with residual metastatic disease. Hence it was concluded that, the bridge therapy may benefit children suffering from neuroblastoma.
