ABSTRACT
PURPOSE:
To evaluate, in a prospective trial, a new combination chemotherapy specifically designed for elderly patients. PATIENTS ANDMETHODS:
From October 1988 to December 1990, 60 previously untreated patients older than 60 years of age with aggressive non-Hodgkin's lymphoma (NHL) were treated at our institution with a new weekly alternating six-drug chemotherapy regimen, P-VABEC. The schedule consisted of doxorubicin, etoposide, and cyclophosphamide alternated weekly with vincristine and bleomycin. Oral prednisone was administered daily during the entire treatment period. Twenty-six of 60 patients were treated for a total of eight courses and 34 of 60 for 12 courses.RESULTS:
A total of 45 patients (75%) achieved a complete response (CR), 10 (17%) a partial response (PR), and five (8%) no response. So far, 20 of 45 CR patients have relapsed, four of 10 PR patients have progressed, and three patients have died while in CR. Twenty-eight patients are still alive and responding (22 CRs, six PRs) after a median follow-up of 25 months. The projected overall survival (OS), disease-free survival (DFS), and event-free survival (EFS) rates at 2 years were 64%, 57%, and 55%, respectively. The outcome of patients treated with eight courses was similar to that of those who received 12 courses of P-VABEC in terms of CR rate and actuarial curves of OS, DFS, and EFS. Hematologic toxicity was mild in all patients.CONCLUSION:
The P-VABEC regimen is active, well tolerated, and one of the briefest first-line chemotherapy regimens so far reported in the treatment of elderly patients with aggressive NHL. However, prospective randomized trials are needed to establish the real advantage of this regimen compared with other standard chemotherapy regimens.
