Purpose: In the previous LNH87-2 study, consolidative high-dose therapy followed by stem cell transplantation (HDT) improved disease-free survival, as well as survival for patients (pts) presenting with two or three factors of the age-adjusted international prognostic index (Aa-IPI) in first complete remission (CR). In order to improve further the outcome of such patients, we conducted a pilot study of consolidative tandem autotranplant.
Patients and methods: Thirty-six patients (pts) under 60 years of age with two or three factors of the Aa-IPI were enrolled. Their main characteristics were: diffuse large B-cell lymphoma (83%), Aa-IPI three factors (50%), and marrow involved (36)%. The procedure consisted of 1) induction with four cycles of ACVBP (doxorubicin, cyclophosphamide, vin-desine, bleomycin, prednisone) 2) in responding pts, peripheral blood stem cell (PBSC) collection after the fourth cycle of ACVBP (11 pts) or after an additional mobilization regimen (Cyclophosphamide - VP16) (17 pts) 3) a first HDT (mitoxan-trone, cyclophosphamide, VP16 and carmustine) followed by PBSC infusion 4) a second HDT (busulfan, carboplatin and melphalan) followed by PBSC infusion. Among the 29 patients responding to induction, 28 received the first HDT and 24 the second.
Results: The rates of three-year-event free survival and survival are 47% (95% confidence interval (95% Cl: 31%63%) and 50% (95% Cl: 37%69%), respectively. Eighteen patients remained free of evolutive disease and 18 patients have died, 15 from disease progression and three from treatment-related toxicity after tandem transplant (two veno-occlu-sive disease and one cerebral toxoplasmosis).
Conclusion: We conclude that tandem transplant did not improve the results of the LNH87-2 study in which patients received a single consolidative HDT.
