A Phase II Trial of Non-Myeloablative Allogeneic Hematopoietic Cell Transplantation for Patients With Relapsed Follicular Non-Hodgkin's Lymphoma Beyond First Complete Response (BMT CTN #0701)

Blood stem cell transplants are one treatment option for people with lymphoma or other types of blood cancers. For this type of treatment, family members or unrelated donors with a similar tissue type usually donate their blood stem cells to the transplant patients. This study will evaluate the effectiveness of a type of blood stem cell transplant that uses lower doses of chemotherapy in people with relapsed follicular non-Hodgkin's lymphoma (NHL).
