  • Patent number: 7358046
    Abstract: The present disclosure provides methods for determining the sensitivity of cancerous cells to various anti-cancer therapies and predicting the efficacy of these therapies. Specifically, the present disclosure provides methods for predicting the efficacy of one or more candidate anti-cancer therapies in a patient, based on determining the sensitivity of the patient's cancerous cells after exposure to candidate anti-cancer therapies in vitro. The disclosure further provides methods for predicting the efficacy of candidate anti-cancer therapies by using an in vitro sensitivity test of the patient's cancerous cells and a surrogate in vivo efficacy test of the patient's cancerous cells grafted into a surrogate host. The disclosure further provides methods for selecting the most efficacious anti-cancer therapy(s) for a patient, thereby avoiding ineffective or unnecessary treatments.
