Baseline total lesion glycolysis identifies high-risk patients with immunosuppressive signatures in early-stage natural killer/T-cell lymphoma.

ABSTRACT:

Background

The post-treatment Deauville scale (DS) and circulating Epstein-Barr virus (EBV)-DNA were used for prediction of long-term remission in natural killer/T-cell lymphoma (NKTCL). However, the baseline biomarkers still remain lacking for clinical application. Here, we hypothesized that 18F-FDG PET/CT, as a measure of total tumor burden, would be a baseline biomarker to identify high-risk NKTCL patients.

Methods

We analyzed PET/CT data in early-stage NKTCL patients (n = 192) receiving pegaspargase-based regimens from 2 independent clinical trials. The prognostic values of radiomic markers including total lesion glycolysis (TLG), standardized uptake value, and metabolic tumor volume were evaluated in the training (n = 127) and validation cohorts (n = 65) with a median f
