Abstract

Introduction: Glioblastomas are the most frequent malignant neoplasm among primary brain tumors in the childhood. Despite the advances in neurosurgery, radiotherapy and chemotherapy, with combination in multimodal approach, overall survival of such patients remains poor and rarely exceeds 10 to 14 months. Several attempts in use of targeted agents such as gefitinib in unselected patient population showed insufficient efficacy. In general perspective the most interesting approach is the selection of patients for targeted therapy based on predictive markers of response.

Methods: We performed the comprehensive analysis of mutational pattern of 30 child high grade brain tumors, due to WHO-classification 2016. Our research was based on the results of mass spectrometry method (OncoCarta, Sequenom, USA), which estimates 298 known mutations in 19 genes.

Results: We revealed 10 mutations in 9 tumors (30%). Mutations were found in BRAF, CDK, HRAS, EGFR, FGFR, MET and PI3K. The most mutated pathway was EGFR - in 20% of the samples (6/30).

Conclusions: Derived results seem to be very promising in usage of new targeted agents, including BRAF-inhibitors, on the final stage of clinical evaluation.
