Using Tumor Models to Determine Treatments

PDO is a three-dimensional experimental model grown in a laboratory from patient's tumour tissues. PDO is used to test different drugs and select the drugs that may work for treating the patient's cancer. Researchers will review participants' PDO drug results from other studies from which they participated in and will identify the drug that seem to have the best effect on the PDO model. Participants will be offered to receive that drug during the study.
