Lastly, our biochemical data were validated using imatinib response data for first-line metastatic disease; patients with predicted exon 18 sensitive mutations had longer progression-free survival than patients with predicted imatinib-resistant mutations. These results provide key evidence that should be used to guide therapy selection for PDGFRA-mutant GIST.

For therapeutic categories, performance reached 0.84 for avapritinib sensitivity and 0.81 for imatinib sensitivity. Prognostic performance was comparable to pathology-based scores, with highest discrimination in the overall cohort and in patients without adjuvant therapy. DL applied to WSIs enables prediction of molecular alterations, treatment sensitivity, and RFS in GIST, performing comparably to established risk scores across international cohorts, providing a baseline for future multimodal predictors.

Functional invasion assays using a panel of patient-derived DMG, H3K27M cells, revealed that microglia-derived fibronectin significantly enhances tumour cell invasiveness, while its chemical inhibition with RGDS peptide or Avapritinib or its genetic silencing using small-interfering RNAs effectively suppresses invasion. Across independent patient cohorts (Kids First, PNOC, and CBTTC), and in archival tissues, DMG tumours were found to exhibit elevated expression of ECM components, and high fibronectin expression that correlated with poor prognosis. These findings suggest that microglia actively contribute to DMG invasiveness through ECM component production, identifying fibronectin as a potential therapeutic target in this lethal paediatric cancer.

A comprehensive multi-metric sustainability assessment-utilizing ten tools including AES, AGREE, BAGI, RGB, and RAPI-confirmed the methods' excellent greenness (e.g., AES score = 90), superior practicality, and robust analytical performance, achieving a high White Index of 94.2%. With a substantially higher throughput of ~ 500 samples/hour and minimal solvent consumption (200µL/well), the proposed MW-SPMs offers a rapid, sustainable, and cost-effective alternative to conventional chromatographic and spectrofluorimetric techniques for routine pharmaceutical analysis, aligning with multiple United Nations Sustainable Development Goals.

Avapritinib provides a favorable initial response in children with RUNX1::RUNX1T1-positive AML harboring KIT mutations, enabling deeper molecular remission; however, response rates decline with prolonged treatment. Avapritinib has a favorable safety profile.

This study delineates a novel MED8-SE-PDGFRA epigenetic axis driving resistance. The combination of avapritinib and venetoclax, co-targeting the oncogenic signal and its transcriptional regulator, presents a translatable dual-targeting strategy to improve outcomes in PDGFRA-driven glioma.

DL applied to WSIs enables prediction of molecular alterations, treatment sensitivity, and RFS in GIST, performing comparably to established risk scores across international cohorts, providing a baseline for future multimodal predictors. Deep learning on histology predicts KIT and PDGFRA mutations in a large international cohort of GISTs from multiple centers Whole-slide image models stratify recurrence-free survival comparable to pathology-based risk scores Prognostic value of deep learning is preserved in adjuvant therapy subgroups, supporting treatment duration decisions.

Eleven (10%) patients experienced TEAEs leading to death, of which 1 was deemed related to avapritinib by the principal investigator. With 4-year follow-up, avapritinib-treated patients with AdvSM experienced deep and durable responses and a favorable benefit-risk profile.
