Patent number: 12086985Abstract: A scoring functions is developed and used for identifying patients who might be responsive to a PD-1 axis directed therapy. The scoring functions are obtained by extracting features from multiplex-stained sections, selecting features that correlate with response to the therapy using a feature selection function, and fitting one or more of the selected features to a plurality of candidate scoring functions. A candidate scoring function showing the desired balance between predictive sensitivity and specificity may then selected for incorporation into a scoring system that includes at least an image analysis system.Type: GrantFiled: March 30, 2021Date of Patent: September 10, 2024Assignees: Memorial Sloan Kettering Cancer CenterInventors: Mehrnoush Khojasteh, Jim F.
