Diffuse Intrinsic Pontine Glioma Management Strategies
Summary
Diffuse intrinsic pontine glioma (DIPG) remains one of the most formidable paediatric brain cancers, with a median survival under one year. Located within the vital pons region, its infiltrative nature precludes surgical resection and renders conventional chemotherapy largely ineffective due to the intact blood–brain barrier and marked tumour heterogeneity. Fractionated focal radiotherapy offers transient symptom relief and modest tumour control but does not alter overall prognosis. Advances in stereotactic biopsy have enabled molecular profiling, revealing recurrent histone H3 K27M mutations and distinct epigenetic subgroups that are driving the development of targeted small-molecule inhibitors and epigenetic therapies. Immunotherapeutic approaches and innovative delivery methods—including convection-enhanced delivery and nanoparticle carriers—are under active investigation to surmount delivery barriers. Concurrently, quantitative imaging biomarkers and radiomic analyses are emerging as indispensable tools for early response assessment, risk stratification and personalised treatment planning. Despite these advances, global clinical practice remains heterogeneous, emphasising the urgent need for harmonised guidelines and multinational collaborative trials to translate molecular discoveries into effective, standardised management protocols.

Technical terms
Diffuse intrinsic pontine glioma (DIPG): A highly invasive, high-grade glioma arising in the paediatric brainstem pons, characterised by rapid progression and poor prognosis.
Radiomics: The computational extraction and analysis of high-dimensional quantitative features from medical images to characterise tumour phenotype and predict clinical outcomes.
T2-weighted magnetic resonance imaging (MRI): An MRI sequence sensitive to water content and tissue heterogeneity, commonly used to delineate tumour boundaries and assess treatment response.
Machine learning prognostic model: An algorithmic framework that identifies patterns within clinical or imaging data to forecast patient outcomes such as survival or treatment response.
Fractionated focal radiotherapy: A treatment approach delivering targeted ionising radiation in multiple small doses to control tumour growth while minimising damage to surrounding healthy tissue.
