It's around 30-35 percent. But it remains an option in young patients with high-risk disease who have available donors. Currently one does not like to think of allogeneic transplants in people who are above 55, although I have done a transplant in someone who was 69 who tolerated the transplant very well. Other modalities of treatment available include radiation. Local radiation, total body radiation, and hemi-body radiation.
Local radiation has a role in spot therapy and in pain relief, mainly.
Total body radiation is being used less and less now, as its toxicity outweighs its efficacy or effectiveness. Hemi-body radiation or radiation of either the upper or the lower half of the body, or the right or the left side of the body, has a role in palliation therapy in advanced disease. Other conventional or standard chemotherapy combinations are still being used. And these include melphalan and prednisone given orally for four days every month. Cyclophosphamide and prednisone on an intermittent or a continuous basis.
