Abstract
Objective: To assess clinical outcomes of newly diagnosed extranodal NK/T-cell lymphoma nasal-type (ENKTL) patients treated with L-asparaginase-containing chemotherapy as first-line chemotherapy. Materials and Methods: We retrospectively reviewed data of new ENKTL patients in Siriraj Hospital, Thailand during 2012–2016. Results: Among 27 patients, 16 were men and 11 were women, and their median age was 52 (range, 25–83) years. The primary sites were the aero-nasal area (23) and skin (4). Clinical stages of ENKTL were I, II, III and IV in 10, 8, 1 and 8 patients, respectively. Patients classified according to the NK cell-lymphoma prognostic index with PINK (27) and PINK-E (19) as low, intermediate, and high were 14, 8, 5, respectively and 11, 4, and 4, respectively. Chemotherapy regimens used were SMILE (24) and AspaMetDex (3). Fourteen patients received post- chemotherapy local radiation. The overall response rate for 26 assessable patients was 69%, with complete response in 14 patients (52%). Median progression-free and overall survival were 32 and 33 months, respectively. The most common L-asparaginase regimen related complications were hypofibrinogenemia (24) and hypersensitivity (9). The overall mortality at follow-up was 14/27 (52%) owing to sepsis (11) and disease progression (3). Discussion: L-asparaginase-based regimens showed similar results as other study results. including those in which hematopoietic stem cell transplantation was performed, suggesting that transplantation can be avoided if it is unaffordable. Thrombosis or bleeding, the regimen side effects, should be carefully monitored during treatment. Conclusions: L-asparaginase-based regimens offer a good outcome as a front-line treatment for ENKTL.
