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.
