Abstract

High-dose chemotherapy (HDT)with autologous stem cell transplantation (ASCT)has been shown to improve the prognosis of patients with central nervous system (CNS)lymphoma. We queried the Japan Society for Hematopoietic Cell Transplantation Registry for 2006 to 2015 to analyze the outcomes of 102 patients with primary CNS lymphoma (PCNSL)who underwent first HDT/ASCT. The median patient age was 54 years (range, 20 to 74 years), and 65 patients were treated in an upfront setting. With a median duration of follow-up of 44 months, the 5-year overall survival (OS)and progession-free survival (PFS)were 54.9% and 38.4%, respectively. There were no significant differences in OS and PFS between upfront and salvage HDT/ASCT. Because thiotepa, a key agent in HDT/ASCT for PCNSL, has been unavailable since 2011 in Japan, the HDT regimens used were not uniform. Thiotepa-containing HDT was received by 16 out of 32 patients before 2010, but by only 2 of 70 patients after 2011. Thiotepa-containing HDT was associated with better PFS (P =.019), lower relapse (P =.042), and a trend toward a survival benefit. In multivariate analysis, noncomplete remission at HDT/ASCT was an independent predictor for OS (hazard ratio [HR], 2.40; 95% confidence interval [CI], 1.25 to 4.58; P =.008)and thiotepa-containing HDT remained significant for PFS (HR,.42; 95% CI,.19 to.95; P =.038). These results confirm the activity of thiotepa-containing regimens.
