This content was provided by Dr. Maciejewski My focus is in patients with types of blood cancers, particularly patients with leukemia, lymphoma and multiple myeloma. I work within the subspecialty of hematology called bone marrow transplant, and what we do is offer therapy using cells to treat diseases that may be resistant to traditional chemotherapy. We also treat patients with this type of therapy if their disease is very aggressive or thought to be not curable with just the traditional forms of chemotherapy. Many years ago, when the first transplants were being done, the candidates for this procedure were quite limited because of the way the patient has side effects from the high doses of chemotherapy - and in some cases radiation therapy - that we used to treat their disease. But now, we're able to offer a wider range of therapies to a wider range of patients. Patients who may have not been candidates in the past are now able to receive less intense types of high-dose chemotherapy that still give them the benefit of a bone marrow transplant.
