Abstract

Introduction

High-dose chemotherapy supported by autologous stem cell transplantation (ASCT) continues to be a standard of care for relapsed diffuse large B-cell lymphoma (DLBCL) and may be considered as a frontline consolidation for a proportion of patients with high-risk features.

Aim

We evaluated the feasibility and safety of ASCT for high-risk DLBCL who are in first complete remission after standard treatment with chemotherapy ± rituximab.

Material and methods

A retrospective analysis of 58 patients (36 males and 22 females) receiving up-front ASCT between 1996 and 2018 for remission consolidation.

Results

Of the diagnosed, fifty patients were in clinical stage ≥ III. Forty-two (72%) of transplanted patients had age-adjusted IPI ≥ 2. The “B” symptoms were present in 34 patients. The conditioning consisted of cyclophosphamide, carmustine, etoposide (CBV) in 32 patients, carmustine, cytarabine, etoposide, melphalan (BEAM) in 18, and 8 patients received bendamustine, cytarabine, etoposide, melphalan (BeEAM). The transplant-related mortality was 0% at day +30 and +100 after ASCT. Median overall survival (OS) was 4.2 years whereas progression-free survival (PFS) reached 3.0 years. The estimated 5-year OS and PFS were found to be 66% and 64%, respectively. The presence of “B” symptoms remained significance in multivariate analysis (HR 4.17 [95% CI: 1.19–14.5]; = 0.02). No grade 3 or 4 non-hematological adverse events were observed.

Conclusions

Up-front ASCT was found to be a safe and feasible procedure with long-term remission in approximately 70% of patients.
