Abstract
Background Autologous stem cell transplantation (auto-SCT) is a treatment option for patients with primary central nervous system lymphoma (PCNSL). Methods In this prospective multicenter study, the effects of blood graft cellular content on hematologic recovery and outcome were analyzed in 17 PCNSL patients receiving auto-SCT upfront. Results The infused viable CD34+ cell count > 1.7 × 106/kg correlated with more rapid platelet engraftment (10 vs. 31 days, P = 0.027) and with early neutrophil recovery (day + 15) (5.4 vs. 1.6 × 109/L, P = 0.047). A higher number of total collected CD34+ cells > 3.3 × 106/kg infused predicted worse 5-year progression-free survival (PFS) (33% vs. 100%, P = 0.028). In addition, CD3+CD8+ T cells > 78 × 106/kg in the infused graft impacted negatively on the 5-year PFS (0% vs. 88%, P = 0.016). Conclusion The cellular composition of infused graft seems to impact on the hematologic recovery and PFS post-transplant. Further studies are needed to verify the optimal autograft cellular content in PCNSL.
