Abstract
Recent advances in anti-cancer chemotherapy and in targeted and immune therapies raise the question whether there is a future for haematopoietic cell transplants. I discuss their importance but in the end the magnitude of these improvements is modest. I point out the efficacy of immune therapy is predominately restricted to B-cell cancers and that many if not most successful immune therapy recipients eventually receive an allogeneic haematopoietic cell transplant, especially those with acute lymphoblastic leukaemia (ALL). I also discuss most allotransplants are done for cancers not treated with current immune therapy. Randomized trials show an autotransplant is better than new drugs in young persons with plasma cell myeloma. Considerable data indicate much of the efficacy of allotransplants results from a non-cancer-specific allogeneic effect not expected to operate with current immune therapies. Lastly, I discuss a role for donor-derived chimeric antigen receptor (CAR)-T-cells in persons relapsing after an allotransplant for B-cell cancers. The sum of these considerations suggest an ongoing role for haematopoietic cell transplants in diverse settings.
