Fludarabine single-agent therapy for relapsed low-grade non-Hodgkin's lymphomas: a phase II study of the German Low-Grade Non-Hodgkin's Lymphoma Study Group.
In a phase II study, 45 patients with advanced low-grade non-Hodgkin's lymphomas (NHLs) who had failed on or had relapsed after first-line chemotherapy were treated with a 5-day regimen of fludarabine, 25 mg/m2/d, by a 30-minute infusion. All patients were pretreated and had received one to 11 preceding regimens (median, three regimens). Histologic subtypes included 17 centrocytic/centroblastic NHLs, three centrocytic NHLs, 23 lymphoplasmocytoid immunocytomas, and one case each of peripheral T-cell and lymphocytic lymphoma. From 38 presently evaluable patients, 12 (31%) cases responded (five [13%] complete and seven [18%] partial remissions). Treatment-associated toxicity was mild to moderate, with myelosuppression comprising the major side effect. From the 12 complete and partial response patients, seven are currently in unmaintained remission for more than 12 months. These data indicate a high activity of fludarabine in heavily pretreated patients with low-grade NHL. Further investigations are warranted to assess the most appropriate usage for this highly promising agent at earlier stages of low-grade NHL therapy.
