We describe adolescents' and parents' interest in hematopoietic stem cell transplant (HSCT) as a cure for sickle cell disease (SCD) and factors associated with increased interest. We administered a 40 question survey to assess the interest in HSCT in parents and adolescents with HBSS or HBSβ(0) thalassemia. The survey tool assessed factors that may influence interest in HSCT including demographic data, disease severity, views on prognosis, and health-related quality of life (HRQOL). All participants were given a handout on the risks and benefits of an HSCT before completing the survey. One hundred twenty-nine parents and 59 adolescents completed the survey. Forty-five percent of parents (54 of 119) would likely have their child undergo HSCT, and 35% of adolescents (19 of 55) would likely undergo HSCT if it was recommended by their hematologist. Parents of adolescents, as well as adolescent patients with better HRQOL, were more interested in HSCT. Prior exchange transfusion was associated with increased interest in HSCT (62% [23 of 37] versus 38% [29 of 76]; P = .02). The majority of parents believe their child's SCD will get better (66%; [80 of 122]), will not likely prevent their child from achieving life goals (83%; [100 of 121]), and will not shorten their child's lifespan (86%; [102 of 119]). There is strong parent and adolescent interest in HSCT as a cure for SCD. It is concerning that few parents and adolescents believe SCD will negatively impact their prognosis. Education on the potential long-term sequelae of SCD is needed when considering the role for HSCT.

CCS ≥ 18 demonstrated prematurely elevated PVW. Further studies are needed to determine the predictive value of PWV in this population and its utility as a screening modality.

Background The prognosis for patients with pediatric high-grade glioma (pHGG) is poor despite aggressive multi-modal therapy. Objective responses to targeted therapy with BRAF inhibitors have been reported in some patients with recurrent BRAF-mutant pHGG but are rarely sustained. Methods We performed a retrospective, multi-institutional review of patients with BRAF-mutant pHGG treated with off-label BRAF +/- MEK inhibitors as part of their initial therapy. Results Nineteen patients were identified, with a median age of 11.7 years (range, 2.3–21.4). Histologic diagnoses included HGG (n=6), glioblastoma (n=3), anaplastic ganglioglioma (n=4), diffuse midline glioma (n=3), high-grade neuroepithelial tumor (n=1), anaplastic astrocytoma (n=1), and anaplastic astroblastoma (n=1). Recurrent concomitant oncogenic alterations included CDKN2A/B loss, H3 K27M, as well as mutations in ATRX, EGFR and TERT. Eight patients received BRAF inhibitor monotherapy. Eleven patients received combination therapy with BRAF and MEK inhibitors. Most patients tolerated long-term treatment well with no grade 4–5 toxicities. Objective and durable imaging responses were seen in the majority of patients with measurable disease. At a median follow-up of 2.3 years (range, 0.3–6.5), three-year progression-free and overall survival for the cohort were 65% and 82%, respectively, and superior to a historical control cohort of BRAF-mutant pHGG patients treated with conventional therapies. Conclusions Upfront targeted therapy for patients with BRAF-mutant pHGG is feasible and effective, with superior clinical outcomes compared to historical data. This promising treatment paradigm is currently being evaluated prospectively in the Children’s Oncology Group ACNS1723 clinical trial.

High-risk neuroblastoma is a highly aggressive solid tumor that most commonly presents in early childhood. Advances in treatment through decades of clinical trials and research have led to improved outcomes. This review provides an overview of the current state of treatment for high-risk neuroblastoma.
