Brief Summary

Allogeneic hematopoietic stem cell transplantation is an important treatment method for NK-T cell lymphoma, but the recurrence rate after transplantation is relatively high. Therefore, exploring efficient and low-toxicity maintenance treatment strategies after transplantation is a key challenge for improving prognosis. Previous studies have reported that selinexor and azacitidine show good anti-tumor activity in relapsed/refractory NKTCL. Thus, we conducted a single-center, single-arm, exploratory study on the efficacy and safety of selinexor combined with azacitidine as maintenance therapy after allogeneic hematopoietic stem cell transplantation for NK/T cell lymphoma, to evaluate the efficacy and safety of the combined regimen, with the aim of providing reference for clinical treatment.

EXPERIMENTAL

For patients with NK/T-cell lymphoma, maintenance therapy with selinexor combined with azacitidine was initiated 60-90 days after allogeneic hematopoietic stem cell transplantation. The specific treatment regimen was as follows: Selinexor 40 mg once a week; if the blood routine was intolerable (i.e., PLT ≤ 50×109/L), 20 mg once a week could be used. Azacitidine 16 mg/m2/d, days 1-5. A 28-day treatment cycle was adopted, and the treatment was continued for 2 years.
