Intensive conditioning regimen of etoposide (VP-16), cyclophosphamide and carmustine (VCB) followed by autologous hematopoietic stem cell transplantation for relapsed and refractory Hodgkin's lymphoma.

Several high-dose therapy regimens are used for autologous hematopoietic stem cell transplantation (auto-HSCT) for relapsed and refractory Hodgkin's lymphoma (HL) with variable disease response. An intensified regimen of etoposide (VP-16) 2400 mg/m2, cyclophosphamide 7200 mg/m2 and carmustine (BCNU) 600 mg/m2 (VCB) pre-auto-HSCT was developed to overcome disease recurrence. A total of 43 relapsed and refractory HL patients underwent auto-HSCT between January 1992 and December 2004. At day 100 there were 37 (86%) complete responses. A total of 40 patients survived beyond day 100, 14 of whom subsequently relapsed/progressed. At a median follow-up of 4.9 years (range 1.5–11.4 years), 26 patients (60%) are alive and disease free. Five-year actuarial event-free survival (EFS) was 53% (95% CI 35–70%) and median EFS was 5.9 years. Median progression-free and overall survivals have not been reached. EFS was reduced with an increasing number of prognostic factors (Karnofsky performance status, KPS <90, chemotherapy-resistant disease and 3 chemotherapy regimens prior to transplant 1 vs 2; P=0.049). Grade III–IV regimen-related toxicity was 9% (n=4). The 1-year cumulative incidence of interstitial pneumonitis (IP) was 36%, however only two patients died of IP complications. Disease progression was the most common cause of death (n=10, 23%). Intensive VCB is an effective and well-tolerated preparative regimen for relapsed and refractory HL auto-HSCT.Bone Marrow Transplantation (2008) 41, 613–619; doi:10.1038/sj.bmt.1705951; published online 10 December 2007 [ABSTRACT FROM AUTHOR]
