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
