First Claim
1. A method of treating a human subject diagnosed with cancer, the method comprising:
- administering to the subject a first agent that is a Human Epidermal growth factor Receptor (HER) family targeted therapeutic that has been determined to be therapeutically active in the signaling pathway it is intended to address in the subject'"'"'s cancer cells, by a method comprising;
culturing a sample comprising viable cancer cells obtained from the subject;
contacting the sample with the first agent and with a second agent that is known to selectively affect the same signaling pathway the first agent is intended to address, so as to upregulate or downregulate the signaling pathway as measured by an effect on cell adhesion or attachment, to produce a sample contacted with both the first agent and the second agent;
continuously measuring cell adhesion or attachment of viable primary or metastatic cancer cells in the sample contacted with both the first agent and the second agent, relative to a sample of viable primary or metastatic cancer cells obtained from the subject which sample is contacted with the first agent or the second agent alone;
determining by mathematical analysis of the continuous measurements an output value, expressed as a percentage, that characterizes whether a change in cell adhesion or attachment has occurred in the sample contacted with both the first agent and the second agent, as compared to the sample contacted with the first agent or the second agent alone; and
administering the first agent to the subject wherein the output value that characterizes the change in cell adhesion or attachment is equal to or greater than 50%, indicating the first agent is therapeutically active in the cell signaling pathway of the subject'"'"'s cancer cells.

Abstract
The disclosure provides methods for analysis of disease cell response to a therapeutic agent. In embodiments, a method comprises administering the therapeutic agent to a disease cell sample from the subject in a device that measures at least one physiological parameter of a cell; determining whether a change occurs in the physiologic parameter of the disease cell sample in response to the therapeutic agent as compared to a baseline measurement or the physiological parameter before administration of the therapeutic agent, and selecting the therapeutic agent that results in the change in the at least one physiologic parameter. In embodiments, the disease cells are whole, viable, and/or label free.
