Panelists discuss how comprehensive post–chimeric antigen receptor (CAR) T follow-up care includes proactive immune system support through IVIG (intravenous immunoglobulin) therapy that rapidly improves immune function within days, resulting in patients achieving complete remission with undetectable light chains, eliminated M spike, negative bone marrow for plasma cells, and minimal residual disease (MRD)-negative status, representing the deepest possible remission, while patients report significantly improved quality of life with better stamina, ability to work in their yards, and freedom from daily chemotherapy compared with traditional treatments, with many describing CAR T as “a walk in the park” compared with stem cell transplant and emphasizing their desire to be healed rather than continuously harmed by ongoing chemotherapy regimens.
