Lomustine (Chloroethyinitrosourea [CCNU]), ifosfamide, bleomycin, vincristine, and cisplatin (CIBO-P) is an effective regimen for patients with poor prognostic refractory or multiple disease recurrent aggressive non-Hodgkin lymphoma

none10BACKGROUND. The current study was designed to assess the activity and safety of a novel combination therapy for patients with recurrent or refractory aggressive non-Hodgkin lymphoma (NHL). METHODS. Forty-three consecutive patients with recurrent or refractory aggressive NHL were treated with lomustine (chloroethylnitrosourea [CCNU]; 60 mg/m(2) on Day 1), ifostamide (1.5 g/m(2) on Days 1, 2 and 21, 22), bleomycin (5 mg/m(2) on Days 1, 5 and 21, 25), vincristine (1.4 mg/m(2) on Days 1, 8 and 21, 28), and cisplatin (25 mg/m(2) on Days 3, 4, 5 and 23, 24, 25), every 42 days (CIBO-P regimen). RESULTS. Thirty-nine patients (91%) were evaluable for response. The median patient age was 63 years. Thirty-five percent of the patients had received 2 lines of previous chemotherapy and 40% had elevated lactate dehydrogenase levels at the time of treatment initiation. The overall objective response rate was 77% (95% confidence interval [95% CI], 63-90%), including 19 (49%) complete (CR) and 11 (28%) partial responses. CIBO-P induced responses in primary refractory disease and in patients treated for second or subsequent disease recurrences. A CR with previous therapy was the most important factor associated with a significantly higher CR rate. The median duration of response was 6 months (95% CI, 4.4-7.7 months) and the median survival duration was 10.7 months (95% CI, 5.9-18.1 months). Five patients (11.6%) remained disease free for ≥ 24 months. By multivariate analysis, a CR with previous therapy and average dose intensity of CIBO-P drugs were independent prognostic factors for time-to-treatment failure, whereas a CR with previous therapy and serum lactate dehydrogenase were independent predictors for survival. Myelosuppression was the most frequent serious complication of this regimen. However, none of the patients had hemorrhage with thrombocytopenia, and only 2 patients (5%) had febrile neutropenia. CONCLUSIONS. In the current study, CIBO-P was a novel, highly active, and safe combination therapy for patients with refractory disease with a poor prognosis or for patients with multiply recurrent aggressive NHL. © 2005 American Cancer Society.noneMusolino A; Perrone MA; Michiara M; Delnevo D; Franciosi V; Di Blasio B; Ceci G; Camisa R; Ardizzoni A; Cocconi GMusolino A; Perrone MA; Michiara M; Delnevo D; Franciosi V; Di Blasio B; Ceci G; Camisa R; Ardizzoni A; Cocconi
