A can be a good treatment for multiple myeloma. A successful transplant gives someone with multiple myeloma new, healthy bone marrow. It replaces the bone marrow harmed by myeloma cells.Hematopoietic (hee-MA-toh-poy-EH-tik) stem cells (usually just called stem cells) grow into all types of blood cells. The white blood cells fight infection, red blood cells carry oxygen, and platelets help control bleeding.You may hear your transplant called a stem cell transplant or a bone marrow transplant. A bone marrow transplant is a type of stem cell transplant.With a bone marrow transplant, the stem cells are taken from the bone marrow.With a stem cell transplant, the stem cells are taken from either the bone marrow or the bloodstream.Types of transplantsThere are 2 main types of stem cell transplants. are the most common type for multiple myeloma. Your stem cells are harvested (collected) from your body and frozen. Your own stem cells are put back in your body after you have chemotherapy. also can treat multiple myeloma. When you have an allogeneic stem cell transplant, stem cells are harvested (collected) from a donor.The transplant processFor either type of transplant, you first get high-dose chemotherapy to kill cancer cells. Two days later, stem cells are infused (put back) into your bloodstream. This procedure is similar to a blood transfusion.Over the next few days, the transplanted stem cells travel to your bone marrow. There, they grow into new mature blood cells.It takes a few weeks for all the mature blood cells to grow and replace old blood cells. During this time, we will protect you from infections and bleeding. You may spend up to 3 weeks at the hospital after a stem cell transplant. Full recovery takes several months.When they work well, autologous and allogeneic transplants give you a new, healthy bone marrow. Allogeneic transplants also give you a new immune system, built from your donor’s stem cells. Your new immune system may help protect you against cancer.Gut microbiota and transplantsProtecting the in people who have transplants can prevent complications and protect their health. Your microbiota is the collection of all the microbes that live on and inside your body. They include viruses, bacteria, and other microorganisms.MSK researchers are studying the connection between changes in the microbiota and successful transplants. We’re studying how the gut microbiome affects someone’s response to treatments with immunotherapy, including ., A stem cell transplant (SCT) is a common treatment for multiple myeloma, especially in people who are younger and otherwise fairly healthy. It can often help people live longer and keep the myeloma in remission longer than if they get just get drug treatments alone., What Is Autologous Stem Cell Transplant (or Bone Marrow Transplant)? The standard of care for fit multiple myeloma patients is to receive high-dose chemotherapy (HDT) with autologous stem cell rescue. This procedure is also known as autologous stem cell transplant (ASCT). Autologous stem cell transplant can provide a deep response with long-term remission. A deep response, having no minimal .
