Comparison of gemcitabine, oxaliplatin and L-asparaginase and etoposide, vincristine, doxorubicin, cyclophosphamide and prednisone as first-line chemotherapy in patients with stage IE to IIE extranodal natural killer/T-cell lymphoma: a multicenter retrospective study.

Optimal chemotherapy regimen for Extranodal natural killer/T-cell lymphoma (ENKTL) has not yet been defined. We retrospectively compared the outcome of 93 patients newly diagnosed with stage IE to IIE ENKTL who received gemcitabine, oxaliplatin and L-asparaginase (GELOX) (n = 40) or etoposide, vincristine, doxorubicin, cyclophosphamide and prednisone (EPOCH) (n = 53) as induction chemotherapy. After induction chemotherapy, the complete response (CR) rate and overall response rate (ORR) for the GELOX group were higher than those for the EPOCH group (70.0% vs. 41.5%, p = 0.007 for CR; 87.5% vs. 67.9%, p = 0.047 for ORR). The GELOX regimen resulted in significantly superior 5-year progression-free survival (PFS) (79.0% vs. 46.5%, p = 0.005) and overall survival (OS) rates (78.9% vs. 50.4%, p = 0.003). Toxicity of both regimens was acceptable. The GELOX regimen produces a better long outcome with less toxicity than the EPOCH regimen for patients with early stage ENKTL.
