abstract = {Central nervous system (CNS) tumors account for the highest
mortality among pediatric malignancies. Accurate diagnosis
is essential for optimal clinical management. The increasing
use of molecular diagnostics has opened up novel
possibilities for more precise classification of CNS tumors.
We here report a single-institutional collection of
pediatric CNS tumor cases that underwent a refinement or a
change of diagnosis after completion of molecular analysis
that affected clinical decision-making including the
application of molecularly informed targeted therapies. 13
pediatric CNS tumors were analyzed by conventional
histology, immunohistochemistry, and molecular diagnostics
including DNA methylation profiling in 12 cases, DNA
sequencing in 8 cases and RNA sequencing in 3 cases. 3
tumors had a refinement of diagnosis upon molecular testing,
and 6 tumors underwent a change of diagnosis. Targeted
therapy was initiated in 5 cases. An underlying cancer
predisposition syndrome was detected in 5 cases. Although
this case series, retrospective and not population based,
has its limitations, insight can be gained regarding
precision of diagnosis and clinical management of the
patients in selected cases. Accuracy of diagnosis was
improved in the cases presented here by the addition of
molecular diagnostics, impacting clinical management of
affected patients, both in the first-line as well as in the
follow-up setting. This additional information may support
the clinical decision making in the treatment of challenging
pediatric CNS tumors. Prospective testing of the clinical
value of molecular diagnostics is currently underway.},
