Primary diagnosis for these patients included Burkitt lymphoma (n=13), Large B-cell lymphoma (n=4), T-Lymphoblastic lymphoma (n=4), NK/T cell lymphoma/leukemia (n=3), Peripheral T-cell lymphoma (n=2), B-lymphoblastic lymphoma ((n=1) and anaplastic large cell lymphoma (n=1). The median age at HCT was 7.65 years (mean 8.2; range 1-14.3). Twenty had suffered a relapse of their disease, while five had primary progression; three patients with NK/T lymphomas underwent HCT as part of their first-line therapy. Fourteen patients had autologous (autoHCT) and 14 had allogeneic HCT (alloHCT). Among alloHCT, 11 had matched-related grafts while 3 had unrelated umbilical cord blood (UCB) grafts. At the time of HCT, 23 patients were in CR (CR1=7, CR2=15, CR3=1), and 5 had partial responses. HCT conditioning was myeloablative for all patients; in 18 patients, it was TBI-based. Fourteen patients suffered recurrence of their lymphoma post HCT at a median of 1.17 months from HCT (mean 6.2; range 0.63-42); 4 died in CR due to transplant-related toxicity, of these 3 were post alloHCT and one post autoHCT. Three patients have developed secondary malignancies (SMN; 2 post alloHCT and 1 post autoHCT). 10 patients were alive at last follow-up, all of whom were in CR. The 5-year estimated OS from SCT is 38.7%, with and EFS of 26%. There was no difference in 5-year OS or EFS among patients who received alloHCT v. autoHCT (OS 28.6% v. 49%; p=0.53, EFS 14.3% v. 37.5%; p=0.25) and among patients who did or did not receive TBI (OS 33.3% v. 48%; p=0.37, EFS 27.8% v. 18.8%; p=0.66).
