People who join a study in the Developmental Therapeutics Clinic (DTC) have tests. These include blood draws and biopsies. Researchers collect data from these samples. Some people take part in more than one study at the DTC. At this time, data are connected only with one single study. Researchers want to access people s medical records. This will allow them to link the research data from all their studies they have or will take part in. Researchers also want to collect medical data about their diagnosis and treatment history. This will allow them to see how their cancer reacted to different drugs over time.
