CNS Tumor Criteria

CNS Tumor Criteria is a professional reference tool for quick consultation of neuro-oncology criteria, biomarkers and scales. It works entirely offline, with no registration and no data collection. WHAT YOU WILL FIND • Universal lookup — search tumour entities, biomarkers, former nomenclature and criteria; search tolerates accents and abbreviations. • Reference cards based on the WHO CNS5 classification (2021, including its corrigendum) — essential and desirable criteria, mimics, discriminating tests and sources. • cIMPACT-NOW layers shown separately as consensus, never as an official WHO classification. • Compatibility check — organise findings with checkboxes (positive / negative / not performed) and see which published criteria the set is compatible with, including the reasoning trail. • Side-by-side differential comparison. • RANO 2.0 reference calculator for response assessment in adult gliomas. • Methodology card with intended use, sources, version and limitations. Coverage: adult-type diffuse gliomas, meningioma, nerve sheath and mesenchymal tumours, ependymal, embryonal/paediatric, germ cell and sellar tumours. Important: this is a reference tool for healthcare professionals. Case examples are simulated. The app does not replace clinical assessment or a specialist report; every decision remains human.
