What the trial is, and whether it could suit you
Extranodal NK/T-cell lymphoma, nasal type (NKTCL) is a common malignant tumor in East Asian populations, often starting in the nasal cavity and spreading to other organs. Associated with EBV infection, NKTCL is aggressive. Early-stage patients typically receive chemo and radiotherapy, with promising outcomes. Recent studies show the potential of immune checkpoint inhibitors in NKTCL treatment. However, optimal treatment sequencing and efficacy remain unclear. This study aims to compare three strategies: (A) Pegaspargase with Sintilimab and radiotherapy; (B) chemo then radiotherapy (PGemOx); (C) sandwich chemoradiotherapy (GELAD). The goal is to identify the best treatment based on 24-month progression-free survival.
