As a result, biology-driven risk stratification and therapy assignment for medulloblastoma remains a major clinical challenge. Here, we report mass spectrometry-based analysis of clinical samples for medulloblastoma subgroup discovery, highlighting a MYC-driven prognostic signature and MYC immunohistochemistry (IHC) as a clinically tractable method for improved risk stratification.We analyzed 56 formalin fixed paraffin embedded (FFPE) medulloblastoma samples by data independent acquisition mass spectrometry identifying a MYC proteome signature in therapy resistant Group 3 medulloblastoma. We validated MYC IHC prognostic and predictive value across two Group 3/4 medulloblastoma clinical cohorts (n=362) treated with standard therapies.After exclusion of WNT tumors, MYC IHC was an independent predictor of therapy resistance and death [HRs 23.6 and 3.23; 95% confidence interval (CI) 1.04-536.18 and 1.84-5.66; P = .047 and < .001]. Notably, only ~50% of the MYC IHC positive tumors harbored MYC amplification. Accordingly, cross-validated survival models incorporating MYC IHC outperformed current risk stratification schemes including MYC amplification, and reclassified ~20% of patients into a more appropriate very high-risk category.This study provides a high-resolution proteomic dataset that can be used as a reference for future biomarker discovery. Biology-driven clinical trials should consider MYC IHC status in their design. Integration of MYC IHC in classification algorithms for non-WNT tumors could be rapidly adopted on a global scale, independently of advanced but technically challenging molecular profiling techniques. 000299528 536__ $$0G:(DE-HGF)POF4-312$$a312 - Funktionelle und strukturelle Genomforschung (POF4-312)$$cPOF4-312$$fPOF IV$$x0 000299528 588__ $$aDataset connected to CrossRef, PubMed, , Journals: inrepo02.dkfz.de 000299528 650_7 $$2Other$$aFFPE proteomics 000299528 650_7 $$2Other$$aMYC 000299528 650_7 $$2Other$$aMedulloblastoma 000299528 650_7 $$2Other$$abiomarker 000299528 650_7 $$2Other$$arisk-stratification 000299528 7001_ $$aBurwag, Fares$$b1 000299528 7001_ $$aBen-Neriah, Susana$$b2 000299528 7001_ $$aSuk, Yujin$$b3 000299528 7001_ $$aShyp, Taras$$b4 000299528 7001_ $$aKosteniuk, Suzanne$$b5 000299528 7001_ $$00000-0002-6244-0584$$aDunham, Christopher$$b6 000299528 7001_ $$aCheng, Sylvia$$b7 000299528 7001_ $$0P:(DE-He78)34b3639de467b2c700920d7cbc3d2110$$aOkonechnikov, Konstantin$$b8$$udkfz 000299528 7001_ $$0P:(DE-He78)e54a1e0999c1d8c95869ef9188b794cc$$aSchrimpf, Daniel$$b9$$udkfz 000299528 7001_ $$0P:(DE-He78)a8a10626a848d31e70cfd96a133cc144$$avon Deimling, Andreas$$b10$$udkfz 000299528 7001_ $$aEllezam, Benjamin$$b11 000299528 7001_ $$aPerreault, Sébastien$$b12 000299528 7001_ $$aSingh, Sheila$$b13 000299528 7001_ $$00000-0003-2618-4402$$aHawkins, Cynthia$$b14 000299528 7001_ $$0P:(DE-He78)4c28e2aade5f44d8eca9dd8e97638ec8$$aKool, Marcel$$b15$$udkfz 000299528 7001_ $$0P:(DE-He78)f746aa965c4e1af518b016de3aaff5d9$$aPfister, Stefan$$b16$$udkfz 000299528 7001_ $$aSteidl, Christian$$b17 000299528 7001_ $$aHughes, Christopher$$b18 000299528 7001_ $$0P:(DE-He78)8d9c904a6cea14d4c99c78ba46e41f93$$aKorshunov, Andrey$$b19$$udkfz 000299528 7001_ $$aSorensen, Poul H$$b20 000299528 773__ $$0PERI:(DE-600)2094060-9$$a10.1093/neuonc/noaf046$$gp. noaf046$$n9$$p2431-2444$$tNeuro-Oncology$$v27$$x1522-8517$$y2025 000299528 909CO $$ooai:inrepo02.dkfz.de:299528$$pVDB 000299528 9101_ $$0I:(DE-588b)2036810-0$$6P:(DE-He78)34b3639de467b2c700920d7cbc3d2110$$aDeutsches Krebsforschungszentrum$$b8$$kDKFZ 000299528 9101_ $$0I:(DE-588b)2036810-0$$6P:(DE-He78)e54a1e0999c1d8c95869ef9188b794cc$$aDeutsches Krebsforschungszentrum$$b9$$kDKFZ 000299528 9101_ $$0I:(DE-588b)2036810-0$$6P:(DE-He78)a8a10626a848d31e70cfd96a133cc144$$aDeutsches Krebsforschungszentrum$$b10$$kDKFZ 000299528 9101_ $$0I:(DE-588b)2036810-0$$6P:(DE-He78)4c28e2aade5f44d8eca9dd8e97638ec8$$aDeutsches Krebsforschungszentrum$$b15$$kDKFZ 000299528 9101_ $$0I:(DE-588b)2036810-0$$6P:(DE-He78)f746aa965c4e1af518b016de3aaff5d9$$aDeutsches Krebsforschungszentrum$$b16$$kDKFZ 000299528 9101_ $$0I:(DE-588b)2036810-0$$6P:(DE-He78)8d9c904a6cea14d4c99c78ba46e41f93$$aDeutsches Krebsforschungszentrum$$b19$$kDKFZ 000299528 9131_ $$0G:(DE-HGF)POF4-312$$1G:(DE-HGF)POF4-310$$2G:(DE-HGF)POF4-300$$3G:(DE-HGF)POF4$$4G:(DE-HGF)POF$$aDE-HGF$$bGesundheit$$lKrebsforschung$$vFunktionelle und strukturelle Genomforschung$$x0 000299528 9141_ $$y2025 000299528 915__ $$0StatID:(DE-HGF)0420$$2StatID$$aNationallizenz$$d2024-12-11$$wger 000299528 915__ $$0StatID:(DE-HGF)0100$$2StatID$$aJCR$$bNEURO-ONCOLOGY : 2022$$d2024-12-11 000299528 915__ $$0StatID:(DE-HGF)0200$$2StatID$$aDBCoverage$$bSCOPUS$$d2024-12-11 000299528 915__ $$0StatID:(DE-HGF)0300$$2StatID$$aDBCoverage$$bMedline$$d2024-12-11 000299528 915__ $$0StatID:(DE-HGF)0199$$2StatID$$aDBCoverage$$bClarivate Analytics Master Journal List$$d2024-12-11 000299528 915__ $$0StatID:(DE-HGF)0160$$2StatID$$aDBCoverage$$bEssential Science Indicators$$d2024-12-11 000299528 915__ $$0StatID:(DE-HGF)1110$$2StatID$$aDBCoverage$$bCurrent Contents - Clinical Medicine$$d2024-12-11 000299528 915__ $$0StatID:(DE-HGF)0113$$2StatID$$aWoS$$bScience Citation Index Expanded$$d2024-12-11 000299528 915__ $$0StatID:(DE-HGF)0150$$2StatID$$aDBCoverage$$bWeb of Science Core Collection$$d2024-12-11 000299528 915__ $$0StatID:(DE-HGF)9915$$2StatID$$aIF >= 15$$bNEURO-ONCOLOGY : 2022$$d2024-12-11 000299528 9201_ $$0I:(DE-He78)B062-20160331$$kB062$$lB062 Pädiatrische Neuroonkologie$$x0 000299528 9201_ $$0I:(DE-He78)HD01-20160331$$kHD01$$lDKTK HD zentral$$x1 000299528 9201_ $$0I:(DE-He78)B300-20160331$$kB300$$lKKE Neuropathologie$$x2 000299528 980__ $$ajournal 000299528 980__ $$aVDB 000299528 980__ $$aI:(DE-He78)B062-20160331 000299528 980__ $$aI:(DE-He78)HD01-20160331 000299528 980__ $$aI:(DE-He78)B300-20160331 000299528 980__ $$aUNRESTRICTED
