[Evaluation of fludarabine-containing regimens versus immunochemotherapy for chronic lymphocytic leukemia].

AIM

to analyze the efficacy of RFC (rituximab, fludarabine, and cyclophosphan), FCM (fludarabine, cyclophosphan, and mitoxantrone), and FC (fludarabine and cyclophosphan) treatment programs in patients with chronic lymphocytic leukemia (CLL) in an open-labeled comparative controlled investigation.

MATERIALS AND METHODS

The paper presents the authors' results of treatment in patients with progressive CLL in 2002 to 2007. The study included 229 patients, of them 78 patients received the RFC program, 72 had the FCM program, and 79 had the FC one.

RESULTS

With the use of RFC, a clinically significant therapeutic effect was obtained in 96% of the patients, a complete remission (CR) was in 80% of the primary patients and in 53% of the pretreated patients. When the FCM program was applied, a positive response was noted in 93% of the patients, CR was seen in 75 and 42% of the primary and pretreated patients, respectively. In the treatment of FC, the total effect was 80%, CR was in 41 and 14% of the primary and pretreated patients, respectively.

CONCLUSION

Comparative analysis of an objective response to therapy has indicated that the effectiveness of the RFC significantly exceeds that of the FCM and FC programs, without enhancing toxicity, which allows he RFC regimen to be regarded as the program of choice in therapy for CLL.
