The 52nd EBMT Annual Meeting was held in Madrid, Spain, from March 22 to 25, 2026. As one of the leading international forums in hematology, the meeting brings together experts worldwide to present advances in transplantation, cellular immunotherapy, and complication management, and remains an important platform shaping the future of hematologic treatment. 

This report highlights a study conducted by Dr. Fan Yang from the team of Prof. Kai Hu at Beijing Gaobo Hospital.

Background

Anti-CD19 CAR-T cell therapy has become an established treatment for patients with relapsed or refractory large B-cell lymphoma after at least two prior lines of therapy. In recent years, combining CAR-T therapy with autologous stem cell transplantation (ASCT) has shown promising activity across several subtypes of relapsed or refractory disease. However, direct comparisons between these two approaches remain limited.

Methods

This study was designed as a single-center, propensity score–matched cohort analysis including 64 patients with relapsed or refractory non-Hodgkin lymphoma. Of these, 32 patients received ASCT combined with CAR-T therapy, while 32 matched patients were treated with CAR-T alone. Matching was performed based on ten baseline characteristics, resulting in well-balanced groups suitable for comparative analysis.

Patients with prior exposure to CAR-T therapy or ASCT were excluded. In the combination group, conditioning was administered using the standard BEAM regimen, and CAR-T cells were infused within two days after reinfusion of CD34-positive hematopoietic stem cells.

Results

In the ASCT plus CAR-T group, the infused CD34-positive cell dose ranged from 2.4 × 10⁶/kg to 9.5 × 10⁶/kg. The median CAR-T cell dose was slightly higher in the combination group than in the CAR-T–alone group. Importantly, stem cell engraftment was not adversely affected by the addition of CAR-T therapy, and no clear relationship was observed between CAR-T expansion and treatment efficacy.

In terms of safety, the incidence of grade 3 or higher cytokine release syndrome was somewhat higher in the combination group, whereas severe neurotoxicity remained uncommon in both groups.

At three months, response rates were numerically higher in the ASCT plus CAR-T group, including a higher complete response rate, although these differences did not reach statistical significance.

After a median follow-up of 38.4 months, survival outcomes were encouraging overall. Patients treated with the combined approach demonstrated a consistent trend toward improved progression-free survival and overall survival compared with those receiving CAR-T alone. Although these differences did not meet statistical significance, the pattern was consistent across endpoints. Similarly, the cumulative incidence of relapse or progression and non-relapse mortality were lower in the combination group, without statistically significant differences.

Conclusion

Compared with CAR-T therapy alone, the combination of ASCT and CAR-T therapy shows a trend toward improved survival outcomes in patients with relapsed or refractory B-cell lymphoma. Larger, prospective studies are needed to confirm these findings.
