MESA Versus ESA in the Treatment of Early Stage NK/T-cell Lymphoma

Overview

Extranodal natural killer (NK)/T-cell lymphoma (ENKTL), nasal type, is a distinct and heterogeneous histopathologic subtype of non-Hodgkin lymphoma (NHL), accounting for 5%\~10%. The frequency of ENKTL among NHL patients is significantly higher in Asia than in Western countries, with poor prognosis. Radiotherapy plus chemotherapy has improved the survival for these patients. But the optimal treatment schedule is controversial. The previous protocols usually contained high dose methotrexate, but the application of them is limited for the toxicity.

In mid-2016, we had the final evaluation of the phase 2 study of MESA with sandwiched radiotherapy in newly diagnosed early stage NKTCL (NCT02825147). We obtained the final overall response rate of MESA with sandwiched radiotherapy, while the 2-year progression free survival rate was not available at that timepoint. To make the study design of sample size more accurate, we changed the primary outcome endpoint from 2-year progression free survival rate to overall response rate. The change had been approved by the Ethics Committee in August 10, 2016. At that time, only fourteen patients were enrolled in NCT02631239.
