Patent number: 11971402Abstract: The present invention relates to methods and kits for prognosing, treating, and managing treatment of cancer in a subject. The methods involve selecting a subject having cancer and obtaining, from the selected subject, a sample containing exosomes or an S100 molecule containing sample. The exosomes or S100 molecule containing sample, respectively, are then contacted with one or more reagents suitable to detect higher or lower levels or the presence or absence of one or more integrins on said exosomes or higher or lower levels or the presence or absence of one or more S100 molecules in the S100 molecule containing sample. The cancer is then prognosed, treatment is administered, or treatment is managed.Type: GrantFiled: April 25, 2016Date of Patent: April 30, 2024Assignee: CORNELL UNIVERSITYInventors: David C.
