About

Extranodal natural-killer (NK)/T-cell lymphoma (ENKTL) is an aggressive subtype of non-Hodgkin lymphoma with a poor prognosis. Notably, patients with advanced-stage disease or early-stage non-upper aero-digestive tract (NUAT) involvement frequently develop hemophagocytic lymphohistiocytosis (HLH), necessitating more effective therapeutic interventions. This Multicenter, Randomized Controlled Clinical Study aimed to compare the efficacy and safety of P-GEMD and P-Gemox in the treatment of newly diagnosed early NUAT or advanced-stage ENKTL.

Full description

This Multicenter, Randomized Controlled Clinical Study aimed to compare the efficacy and safety of P-GEMD and P-Gemox in the treatment of newly diagnosed early NUAT or advanced-stage ENKTL. The P-GEMD regimen (pegaspargase; gemcitabine; etoposide; mitoxantrone hydrochlorid liposome; dexamethasone) was administered intravenously every 3 weeks until up to 6 cycles of planned therapy. The P-Gemox regimen ( Pegaspargase, Gemcitabine, and Oxaliplatin) was administered intravenously 3 weeks until up to 6 cycles of planned therapy.
