PDX

Tumor tissue that has been taken from a patient and implanted into mice for research purposes. Cancer drugs and other types of treatment may be tested on xenografts to see how well they work before they are given to the patient. PDXs may be used to help plan treatment and learn what the best treatment may be for a patient. They are also being used in the development of new cancer drugs. Also called patient-derived xenograft.
