FOXP1 and neuroblastoma: We noticed that low FOXP1 expression was associated with poor EFS (Figure 1e; 5-year EFS 0.49 ± 0.03 vs. 0.85 ± 0.02; P < 0.001) and OS (Figure 1f; 5-year OS 0.60 ± 0.04 vs. 0.93 ± 0.02; P < 0.001), demonstrating that FOXP1 transcript levels discriminate neuroblastoma patients with beneficial and adverse outcome.
