A prospective study of VEC-POB and POCE chemotherapy in aggressive non-Hodgkin's lymphoma

The optimal combination and scheduling of chemotherapy for aggressive non-Hodgkin's lymphoma is unclear, and the elderly have a poor tolerance to treatment. A Phase II prospective study was undertaken using outpatient weekly combination chemotherapy: the VEC-POB (etoposide, epirubicin, cyclophosphamide, cisplatin, Oncovin, bleomycin, and prednisone) regimen in patients < 60 years and less intensive POCE (etoposide, Oncovin, cyclophosphamide, and epirubicin) in patients > or = 60 years. All patients with intermediate and high-grade lymphoma (International Working Formulation) with bulky disease and/or advanced stages (III, IV) seen between January 1991 and June 1992 were entered. Of 29 patients treated with VEC-POB, 23 patients (79%) achieved complete remission (CR), with one (3%) toxic death. Overall survival at 29 months is 67%, and disease-free survival at 60 months is 60%. Of 29 patients treated with POCE, 14 achieved CR, with three (10%) toxic deaths. Overall survival is 58% at 18 months, and disease-free survival at 10 months is 50%. Adverse prognostic factors were analyzed. The results are comparable to the best results achieved with other regimens, and toxicity is acceptable.
