High-dose chemotherapy with carboplatin, etoposide and ifosfamide followed by autologous stem cell rescue in patients with relapsed or refractory malignant lymphomas: a phase I/II study.
Patients with relapsed or refractory non-Hodgkin's lymphomas (NHL) and Hodgkin's disease (HD) with recurrences after an anthracyclin-containing regimen only have a chance of cure of below 10% with conventional chemotherapy. In order to improve their prognosis, we started a phase I/II trial using high-dose therapy comprising carboplatin, together with etoposide and ifosfamide (CEI), followed by autologous stem cell rescue (ASCR) as consolidation after salvage treatment. Since September 1990, 40 patients with intensively pretreated advanced NHL (n = 24) or HD (n = 16) received one cycle of high-dose therapy (HDT) consisting of carboplatin 1500 mg/m2, ifosfamide 10 g/m2 and etoposide in escalating doses from 1200 mg/m2 to 2400 mg/m2 followed by ASCR. Thirty-nine patients were assessable for toxicity and response. The following doses appeared to be safe: carboplatin 1500 mg/m2, etoposide 2400 mg/m2 and ifosfamide 10 g/m2. All patients developed grade 3 nausea and grade 3 or 4 mucositis. Granulocytopenic fever occurred in 100% with grade 4 infections in 15%. Mild transient kidney toxicity was noted in 36% and liver toxicity in 20% of patients. One toxic death occurred (2.5%). Objective responses were obtained in 36 of 39 patients (92%) with complete remissions (CR) in 24 patients (61.5%) and partial remissions (PR) in 12 (30.7%). Median observation time for surviving patients was 23.3 months (range 3.4-52.3). The probabilities of overall, event-free and relapse-free survival at 2 years are 62, 39 and 55%, respectively. Patients with primary refractory disease or resistant relapse had a poor prognosis. High-dose carboplatin, etoposide and ifosfamide plus autologous stem cell rescue represents an effective, potentially curative salvage treatment with acceptable toxicities.
