VIM3‐ARA C: An effective salvage regimen in refractory or recurrent aggressive non hodgkin's lymphoma. A report on 18 cases

Based on encouraging results of previous combination regimens, we used a combination of VM26, ifosfamide, methylGAG, mitoxantrone (or adriamycin), high‐dose (HD) methotrexate and HD Ara C to treat 18 patients with relapsed or refractory NHL. Front‐line therapy had been in most of them a reinforced CHOP regimen. Twelve patients (67 per cent) responded: there were nine (50 per cent) partial responses (PR) and three (17 per cent) complete remissions (CR). Nine of these 12 responders were grafted (eight autologous. one allogeneic transplants), one relapsed before autograft could be performed and the two remaining patients were excluded from autograft because of positive bone marrow. Five of nine patients remained free of disease after 11 + to 27 + months. Response rate was higher in patients who relapsed ‘off’ therapy (2/3), but CR was also obtained in two refractory NHL and persisted for 11 + and 26+ months, suggesting that VIM3‐ARA C was, at least partially, non‐cross‐resistant with front‐line adriamycin‐containing regimens.
