The role of tumor molecular profiling in directing targeted therapy utilization remains to be defined for pediatric tumors. We aimed to evaluate the feasibility of a sequencing and molecular biology tumor board (MBB) program, and its clinical impact on children with solid tumors.
We report on a single-center MBB experience of 60 pediatric patients with a poor prognosis or relapsed/refractory solid tumors screened between October 2014 and November 2015. Tumor molecular profiling was performed with panel-based next-generation sequencing and array comparative genomic hybridization.
Mean age was 12 ± 5.7 years (range 0.1-21.5); main tumor types were high-grade gliomas (n = 14), rare sarcomas (n = 9), and neuroblastomas (n = 8). The indication was a poor prognosis tumor at diagnosis for 16 patients and relapsed (n = 26) or refractory disease (n = 18) for the remaining 44 patients. Molecular profiling was feasible in 58 patients. Twenty-three patients (40%) had a potentially actionable finding. Patients with high-grade gliomas had the highest number of targetable alterations (57%). Six of the 23 patients subsequently received a matched targeted therapy for a period ranging from 16 days to 11 months. The main reasons for not receiving targeted therapy were poor general condition (n = 5), pursuit of conventional therapy (n = 6), or lack of pediatric trial (n = 4).
Pediatric molecular profiling is feasible, with more than a third of patients being eligible to receive targeted therapy, yet only a small proportion were treated with these therapies. Analysis at diagnosis may be useful for children with very poor prognosis tumsors.
