Trofosfamide in non-Hodgkin's lymphoma. A phase II study.

Twenty-three patients (12 females, 11 males) with malignant non-Hodgkin's lymphoma were treated with oral trofosfamide 50 mg t.i.d. Median age was 72 years. Fifteen patients had low-grade and 8 had high-grade lymphomas. Twenty-one patients had stage III and IV disease. Seven patients had WHO performance status of 3-4. The overall response rate was 61% (CR 22%, PR 39%) and the median duration of response 4 months (range 1.5-15+). The main side-effect was bone marrow depression and 7 patients experienced grade II or III hematological toxicity. No gastrointestinal or renal toxicity, no hair loss and no neurotoxicity were observed. The subjective tolerance was good.
