Abstract: 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.

Abstract: The present disclosure relates to methods that involve obtaining a tissue or liquid biopsy sample from a subject. Extracellular vesicles and particles are separated from the sample, and protein from the separated extracellular vesicles and particles is isolated to form an extracellular vesicle and particle protein sample. The extracellular vesicle and particle protein sample is subjected to a detection assay suitable for detecting the sample's protein signature, and the presence, absence, status, and/or type of cancer in the subject is identified based the detected protein signature.
