1. A method for assessing a response to administration of a chemotherapeutic or biological therapeutic agent to an individual, comprising: (a) obtaining a first tissue or cell sample from the individual before exposing the individual to the chemotherapeutic or biological therapeutic agent; (b) obtaining a second tissue or cell sample from the individual after exposing the individual to the chemotherapeutic or biological therapeutic agent; (c) detecting the amount of one or a plurality of biological markers in the first and second tissue or cell sample; (d) comparing the amount of the one or a plurality of biological markers in said first and second tissue or cell sample; (e) determining whether expression or activation of the one or a plurality of biological markers decreases following exposure to the chemotherapeutic or biological therapeutic agent when the amount of the one or a plurality of biological markers in the second tissue sample is less than the amount of the one or a plurality of biological markers in the first tissue sample; wherein a response to the administration of a chemotherapeutic or biological therapeutic agent to an individual is assessed.
