- We assessed the efficacy and toxicity of etoposide, methylprednisolone, high-dose cytarabine, and oxaliplatin (ESHAOx) combination chemotherapy in patients with refractory or relapsed Hodgkin’s lymphoma (HL). This was an open-label, non-randomized, multi-center phase II study. The ESHAOx regimen consisted of intravenous (i.v.) etoposide 40 mg/m2 on days 1 to 4, i.v. methylprednisolone 500 mg on days 1 to 5, i.v. cytarabine 2 g/m2 on day 5, and i.v. oxaliplatin 130 mg/m2 on day 1. Cycles (up to six) were repeated every 3 weeks. In an effort to identify prognostic markers, the serum levels of cytokines including tumor necrosis factor-α (TNF-α), C-reactive protein (CRP), and vascular endothelial growth factor (VEGF) were measured at the time of study entry. A total of 37 patients were enrolled, and 36 were available for evaluation of tumor response. The overall response rate was 72.2% (26/36) (complete response, 33.3% [12/36]; partial response, 38.9% [14/36]). The median time to progression was 34.9 months (95% confidence interval, 23.1–46.7 months). The most common grade 3 or 4 hematological adverse events were neutropenia (16/37, 43.2%), followed by thrombocytopenia (10/37, 27.0%). Grade 3 or 4 non-hematological adverse events were nausea (3/37, 8.1%), anorexia (2/37, 5.4%), mucositis (1/37, 2.7%), and skin rash (1/37, 2.7%). There were no treatment-related deaths. High levels of TNF-α and CRP were significantly associated with poorer overall survival (p = 0.00005 for TNF-α, p = 0.0004 for CRP, respectively). The ESHAOx regimen exhibited antitumor activity and an acceptable safety profile in patients with refractory or relapsed HL.
