Latest Patents

Chang Xu holds a patent titled "Cancer risk stratification based on histopathological tissue slide analysis." This patent presents systems and computer-implemented methods designed to provide reliable risk stratification for early-stage cancer patients. The technology predicts the recurrence risk of patients and categorizes them into high or low-risk groups. A digital pathology system automatically analyzes a series of slides depicting serial sections of cancerous tissue. A score for these sections is calculated, and a Cox proportional hazards regression model is employed to stratify patients accordingly. This model utilizes training data comprising survival data for multiple patients and their respective tissue sections, allowing for a comprehensive scoring algorithm.
