Near-term implementable finding

Deep Learning for Differentiating Pulmonary Metastasis from Primary Lung Cancer Constructed on Frozen Sections for Intraoperative Diagnosis.

AI model rapidly differentiates lung cancer types from frozen tissue during surgery, supporting real-time surgical decisions under time pressure.

Onozato et al. developed and validated a deep learning model trained on intraoperative frozen section histological images that accurately differentiates pulmonary metastasis from primary lung cancer, achieving high diagnostic accuracy in Modern Pathology. The model addresses a critical time-pressure intraoperative diagnostic scenario, offering AI-assisted decision support when tissue sampling is limited and definitive histological classification is urgently required to guide surgical resection extent.
