A Foundation Model of Cancer Genotype Enables Precise Predictions of Therapeutic Response.

MutationProjector, a cancer genotype foundation model, accurately predicts therapeutic resistance and sensitivity across multiple cancer types, surpassing existing methods in all tested contexts.

• Why it matters: Understanding how complex tumor mutation profiles influence treatment response is critical for personalized cancer therapy, yet translating genetic data into actionable insights remains a major challenge.
• What they did: The model was pre-trained on over 30,000 tumor genomes, integrating extensive molecular knowledge to interpret altered pathways and predict resistance or sensitivity to immunotherapy and chemotherapy.
• The result: It successfully identifies novel biomarkers like KMT2D mutations and combined SMARCA4/STK11 alterations, enabling more precise, mechanism-based treatment decisions and advancing personalized oncology.
