Boosting transplants with natural killers: new combo therapy aims to stop blood cancer return

This study tested whether adding ready-made natural killer (NK) cells from a donor to a standard stem cell transplant could safely reduce the chance of cancer returning in people with high-risk myeloid cancers like acute myeloid leukemia, myelodysplastic syndrome, and chronic myeloid leukemia. Twenty-four adults aged 18 to 70 received the combination treatment. The goal was to see if this approach improves outcomes without causing graft failure or early death from causes other than relapse.
