Chimeric antigen receptor (CAR) T-cell therapy is one of the hottest advances in lymphoma treatment, but who should get it and what does the process look like? Allison Winter, MD, of the Cleveland Clinic helps answer those questions on the podcast. She joins Blood & Cancer host David H. Henry, MD, of the Pennsylvania Hospital, Philadelphia, to break down the side effects and look ahead to possible off-the-shelf products.
In Clinical Correlation, Ilana Yurkiewicz, MD, of Stanford (Calif.) University discusses optimism bias. She recalls a time when a patient’s drive for optimism affected what she told them and whether that was a good or bad thing.

- What is the process for a patient to get CAR T-cell therapy?

- Reception of genetically modified T cells by patients.
- Administration of lymphodepleting chemotherapy.
- Admission to the hospital for CAR T-cell infusion.
