SYSTEMS AND METHODS FOR PREDICTING LUNG CANCER IMMUNE THERAPY RESPONSIVENESS USING QUANTITATIVE TEXTURAL ANALYSIS

摘要

Methods and apparatus for predicting responsiveness to immune therapy in lung cancer. The method includes the steps of: identifying a first population of known responders and a second population of known non-responders; processing imaging data for the first and second populations using quantitative textural analysis (QTA); generating, for each member of both populations, quantitative metrics using the QTA; performing logistical regression on the quantitative metrics for both populations to yield a predictive signature expressed in the form of Y = Mx + B where x comprises mean pixel density; performing QTA on a lung cancer scan for a subsequent patient; comparing the predictive signature to one or more relevant metrics associated with the subsequent patient; and predicting responsiveness to immune therapy for the subsequent patient based on the comparison.
