Autologous tandem transplantation in patients with primary progressive or relapsed/refractory lymphoma.

ABSTRACT

Patients with primary progressive or refractory Hodgkin's disease (HD) or aggressive non-Hodgkin's lymphoma (NHL) have a particularly poor prognosis. Here we report the results of autologous tandem transplantation in these patients. Patients aged 18-55 years with primary progressive or refractory relapsed HD and aggressive NHL were included. Patients received high-dose etoposide (2000 mg/m(2)) followed by peripheral blood stem cell harvest (PBSC). The first high-dose chemotherapy (TMC) consisted of thiotepa (750 mg/m(2)), mitoxantrone (40 mg/m(2)), and carboplatin (990 mg/m(2)). Patients with no change (NC), partial remission (PR), or complete remission (CR) after TMC then received BEAM with carmustine (300 mg/m(2)), etoposide (1200 mg/m(2)), cytarabine (1600 mg/m(2)), and melphalan (140 mg/m(2)). Patients with bulky disease (>5 cm) or residual lymphoma received involved field radiotherapy. Twenty-five patients were included (HD=10, NHL=15, median age 34 years). Two patients with HD achieved a CR and five patients a PR [response rate (RR) 70%]. Three patients (30%) experienced treatment failure including two deaths due to peritransplant complications. Five patients with aggressive NHL were in CR and two patients in PR (RR 46%). Of the eight patients (56%) with treatment failure, three had progressive disease and five died from peritransplant complications. Freedom from treatment failure (FFTF) and overall survival (OS) for all patients after 12 months was 28% and 40%, respectively. Tandem HDCT followed by autologous stem cell transplantation (ASCT) offers a chance of cure in these poor prognostic patients, but is associated with risks.
