abstract = {DNA methylation profiling, recently endorsed by the World
Health Organisation (WHO) as a pivotal diagnostic tool for
brain tumours, most commonly relies on bead arrays. Despite
its widespread use, limited data exist on the technical
reproducibility and potential cross-institutional
differences. The LOGGIC Core BioClinical Data Bank registry
conducted a prospective laboratory comparison trial with 12
international laboratories to enhance diagnostic accuracy
for paediatric low-grade gliomas, focusing on technical
aspects of DNA methylation data generation and profile
interpretation under clinical real-time conditions.Four
representative low-grade gliomas of distinct histologies
were centrally selected, and DNA extraction was performed.
Participating laboratories received a DNA aliquot and
performed the DNA methylation-based classification and
result interpretation without knowledge of tumour histology.
Additionally, participants were required to interpret the
copy number profile derived from DNA methylation data and
conduct DNA sequencing of the BRAF hotspot p.V600 due to its
relevance for low-grade gliomas. Results had to be returned
within 30 days.High technical reproducibility was observed,
with a median pairwise correlation of 0.99 (range 0.94-0.99)
between coordinating laboratory and participants. DNA
methylation-based tumour classification and copy number
profile interpretation were consistent across all centres,
and BRAF mutation status was accurately reported for all
cases. Eleven out of 12 centres successfully reported their
analysis within the 30-day timeframe.Our study demonstrates
remarkable concordance in DNA methylation profiling and
profile interpretation across 12 international centres.
These findings underscore the potential contribution of DNA
methylation analysis to the harmonisation of brain tumour
diagnostics.},
