<unk>  is the<unk>  in which<unk> s from the original stem cell<unk>  are infused, after the transplant, to augment an anti-tumor immune response or ensure that the<unk>  stem cells remain engrafted. These donated white blood cells contain cells of the immune system that can recognize and destroy cancer cells. The goal of this therapy is to induce a remission of the patient's cancer by a process called the graft-versus-tumor effect (GVT). The<unk>  T-cells can attack and control the growth of residual cancer cells providing the GVT effect. It is hoped that the<unk>  leukocyte<unk>  will cause GVT and lead to a remission of the patients cancer. Patients might require standard chemotherapy, to reduce the amount of cancer cells they have prior to their<unk> .
