title: Indications and relative indications for stem cell transplantation in non-Hodgkin's lymphoma.
abstract: High dose chemotherapy with or without total body irradiation and autologous stem cell rescue has proven to be effective treatment to cure patients with relapsed intermediate grade and high grade non-Hodgkin's lymphoma. Important factors for selection of candidates most likely to do well with these approaches include patients whose disease is responsive to conventional therapy and those who have minimal disease volume at the time of transplant. The treatment-related mortality of autologous stem cell transplantation has diminished from 20% to less than 5% with improved supportive care and selection of patients with less advanced disease. Although the treatment-related mortality of allogeneic stem cell transplantation may be as high as 20-40%, a graft versus lymphoma effect may decrease relapse with the result that overall survival is not substantially different between autologous and allogeneic transplantation. The definitive indications for stem cell transplantation include patients who have relapsed with intermediate or high grade NHL. Relative indications include intermediate/high grade non-Hodgkin's lymphoma patients, "high risk" first complete remission (CR), resistant relapse; low grade non-Hodgkin's lymphoma in sensitive or resistant relapse, advanced disease (sensitive or resistant relapse, transformation), first CR (younger patients). Relative contraindications include specific patient profiles such as bulky high grade lymphoma which progresses on appropriate conventional therapy, poor performance status, active serious infection, serious cardiac, renal, pulmonary or liver dysfunction, active, central nervous system (CNS) disease unresponsive to cranial irradiation/intrathecal therapy. For patients with previous marrow involvement or active marrow involvement at the time of harvest or transplant, "purged" autografts, peripheral blood stem cell transplantation and allografts have been used successfully.
