[MTX-HOPE (methotrexate, hydrocortisone, vincristine, sobuzoxane, and etoposide) as a low-dose salvage chemotherapy for recurrent or refractory non-Hodgkin's lymphoma].

We conducted a clinical study of MTX-HOPE (day 1, methotrexate 20 mg per os (po); day 2, hydrocortisone 100 mg intravenous (iv), vincristine 1 mg iv; day 3,4 sobuzoxane 400 mg po; etoposide 25 mg po, repeating every 2 or 3 weeks) in 14 relapsed or refractory patients with non-Hodgkin's lymphoma. Ten responders were obtained 5 CR and 5 PR), and heavily treated patients were included in the responders. The median duration of over all survival which was estimated with Kaplan-Meier curve was 11.1 months (range, 2-18+ months), and the median duration of response was 6.9 months (range, 0.8+ -16.4+ months). Out of the 14 patients,eleven were treated with this regimen in an outpatient setting. Grade 4 neutropenia and thrombocytopenia were observed in 4 and 2 patients,and grade 3 GPT-elevation and stomatitis in two and one, respectively. This newly developed MTX-HOPE therapy may be a promising treatment option for such patients as are intolerable for high-dose chemotherapies with PBSC rescue or wish for outpatient therapy.
