Improved prognosis of advanced-stage extranodal NK/T-cell lymphoma: results of the NKEA-Next study.

ABSTRACT: A retrospective study of extranodal natural killer/T-cell lymphoma (ENKL) patients diagnosed between 2014 and 2021 in Japan was conducted. Among 351 patients with sufficient data, 116 (33%) were in the advanced stage (5 in stage III and 111 in stage IV) at diagnosis, and were further analyzed. The median age was 60 years (range: 19-90), and 68 (59%) were male. Ninety-four (85%) of stage IV patients had two or more extranodal involvements. The most common first-line regimen was SMILE (steroid, methotrexate, ifosfamide, L-asparaginase, and etoposide; 52%). The 2-year overall survival (OS) for all patients was 38.5%, which was significantly improved after 2017 (25.2% for 2014-2017 vs. 50.7% for 2018-2021; P = 0.008). Patients treated with SMILE showed better OS than those treated with DeVIC o
