INTERVENTIONAL
Conditions
Summary
The goal of this clinical trial is to learn if the regimen of dexamethasone, azacitidine, pegaspargase and tislelizumab (DAPT regimen) combined with radiotherapy works to treat stage I or II NK/T cell lymphoma in adults. It will also learn about the safety of the DAPT regimen. The main questions it aims to answer are: What are the efficacy of the DAPT regimen plus radiotherapy in participants with extranodal NK/T-cell lymphoma? What medical problems do participants have when taking the DAPT regimen? Participants will: Receive the DAPT regimen every 21 days for 6 cycles and radiotherapy Visit the clinic according to clinical trial requirement for checkups and tests Receive blood tests and radiological imaging tests according to the clinical trial requirement

Interventions
Patients receive 6 cycles of DAPT regimen plus concurrent radiotherapy. The DAPT regimen is administered as follows: dexamethasone 10mg intravenously on days1-3, azacitidine 100mg subcutaneously on days 1-5, pegaspargase 2500IU/m2 intramuscularly on day 1, and tislelizumab 200mg intravenously on day 6, repeated every 21 days. Concurrent radiotherapy given to the tumor sites is started after 2 cycles of DAPT regimen. The specific doses and methods of radiotherapy are in accordance with the clinical guidelines for NK/T-cell lymphoma.
