About

Extranodal NK/T-cell lymphoma is a rare and highly aggressive subtype of non-Hodgkin lymphoma. While the overall survival rates have improved for early-stage ENKTL patients, the prognosis for those with advanced disease remains poor, and there is currently no standard treatment. PD-1/PD-L1 inhibitors have demonstrated significant efficacy in various cancers, and recent studies have shown promising results in extranodal NK/T-cell lymphoma as well. Although PD-1 antibodies have exhibited efficacy in relapsed or refractory patients, their effectiveness when combined with chemotherapy as a first-line treatment remains unclear. This study aims to evaluate the efficacy and safety of sintilimab combined with chemotherapy in a randomized controlled trial for newly diagnosed advanced extranodal NK/T-cell lymphoma patients, while also exploring potential biomarkers that may predict treatment outcomes, offering new therapeutic options for extranodal NK/T-cell lymphoma patients.
