New AI Tool Boosts Precision Medicine in Treating CNS Cancers
Harvard Medical School researchers have developed an AI system that distinguishes glioblastoma from other brain tumors during surgery. The tool called PICTURE achieved 99.8% accuracy in differentiating glioblastoma from primary central nervous system lymphoma. This rare malignancy is frequently misdiagnosed as glioblastoma, yet the AI system outperformed nine human neuropathologists who misclassified lymphoma as glioblastoma in 38% of test cases. With over 100 distinct subtypes, central nervous system tumors involve exceptional diagnostic complexity. Glioblastoma represents the most common variety, with patients typically receiving surgical tumor removal but facing a median survival of just eight months. Primary CNS lymphoma shares overlapping…
