title: Role of a second transplant in the management of poor-prognosis lymphomas: a report from the European Blood and Bone Marrow Registry.
abstract: OBJECTIVE
  Treatment of selected patients with poor-prognosis lymphomas with high-dose chemotherapy and marrow or peripheral stem-cell rescue improves prognosis. A second course of myeloablative chemotherapy has been given to some patients, but few data are available on the indications, morbidity, and overall survival associated with this approach. This study was undertaken to evaluate morbidity and identify subgroups of patients who may benefit from a second transplant.
  
  
  METHODS
  Thirty-four patients with lymphoma given two cycles of myeloablative chemotherapy and entered onto the European Blood and Bone Marrow Transplant (EBMT) registry between 1982 and 1995 were included in this study: Hodgkin's disease (HD), n = 12; intermediate/high-grade non-Hodgkin's lymphoma (HG-NHL), n = 17; and low-grade non-Hodgkin's lymphoma (LG-NHL), n = 5. The reason for second transplant, status at transplant, conditioning regimen, morbidity, and both progression-free survival (PFS) and overall survival (OS) were assessed.
  
  
  RESULTS
  The second procedure was performed for the following reasons: (1) elective double procedure in four patients, (2) relapse after first transplant in 20, (3) partial remission (PR) after first transplant in eight, and (4) refractory disease after first transplant in two. The OS rate at 2 years for patients who underwent two transplants (estimated from the date of second transplant) was 49%, with a median follow-up time of 44 months. The OS rate at 2 years by histologic subtype was as follows; HD, 50%; HG-NHL, 60%; and LG-NHL, 0%. Seven of 15 patients with HD or HG-NHL who relapsed after they had achieved a posttransplant complete remission (CR) remain in CR 13 to 36 months after the second transplant, compared with two of 10 patients in CR (at 6 and 19 months after second transplant) who achieved a PR or had refractory disease after the first transplant. There were eight deaths (24%) before 3 months, of which three (9%) were transplant-related and the remainder due to persistent disease. Three late toxic deaths occurred: two of cardiovascular disease and one of secondary leukemia.
  
  
  CONCLUSIONS
  Selected patients with HD and HG-NHL whose disease recurs after one transplant may benefit from a second transplant. Patients with refractory disease and LG-NHL did not benefit from a second transplant.
