Natural killer/T-cell lymphoma (NKTCL) patients with relapsed/refractory disease had very poor outcome. Anti-PD-1 antibody showed promising results in response, but but the complete remission rate of was low. Some anti-PD-1 antibody based regimen showed higher and deeper response in NKTCL patients.


About 20-30% of early-stage patients and 40-60% of late-stage NKTCL patients will experience disease relapse and refractory disease, and the median survival time of relapsed patients is about 6 months. PD-1 antibody is an effective drug for the treatment of patients with relapsed/refractory NKTCL, but the response rate and complete remission rate of monotherapy are low. How to improve the prognosis of patients is an important way to try combination therapy. In this study, we aim to explore the effectiveness and safety of a novel anti-PD-1 antibody, tislelizumab, in combination with different drugs (tislelizumab plus azacytidine and lenalidomide, or tislelizumab plus etoposide and pegaspargase) to treat refractory NK/T.
