Extended Data Fig. 8: Visualization of model attention showed regions of importance in survival prediction for lung cancer patients.
From: A pathology foundation model for cancer diagnosis and prognosis prediction
In patients with shorter-term survival, CHIEF paid high levels of attention to lesional regions with high tumor cellularity and strands of fibrosis in lung adenocarcinoma, tumor budding in squamous cell carcinoma, and necrotic regions in both types of lung cancers. In contrast, highly attended regions in patients with lower mortality risks highlighted dyskeratosis in lung squamous cell carcinoma.
