A method for predicting a response of a cancer patient's cancerous tumor to an oncology drug and developing a personalized therapy for the patient for treatment of the cancerous tumor, the method comprising the steps of:
- a) obtaining cancer cells from the patient's cancerous tumor;
- (b) culturing the cancer cells in WIT-OC, WIT-L, or WIT-OCe cell culture medium;
- (c) contacting the cultured cancer cells with the oncology drug;
- (d) determining an IC50 OR IC90 value for the oncology drug in the cultured cancer cells;
- and
- (e) correlating an increased IC50 or IC90 value relative to an IC50 or IC90 value for the oncology drug in control cultured cells with a poor response of the patient's cancerous tumor to the oncology drug and correlating a normal or low IC50 or IC90 value relative to the IC50 or IC90 value for the oncology drug in control cultured cells with a positive response of the patient's cancerous tumor to the oncology drug.
