ABSTRACT: Although autologous stem cell transplantation (ASCT) for patients with relapsed/refractory Hodgkin lymphoma (HL) appears to offer a survival advantage over conventional therapy, only approximately 25% to 35% of patients with primary progressive or poor-risk recurrent HL can achieve durable remission after ASCT, with disease progressive after transplant accounting for most of the treatment failures. We conducted a pilot study to evaluate the toxicities and efficacy of a tandem transplant approach in this subgroup of patients. Between April 1998 and March 2000, 46 patients were enrolled in the study. Eligibility criteria: primary progressive (n = 28) or recurrent HL (n = 18) with at least 1 of the following poor prognostic factors: first complete remission (CR) <12 months (n = 15) or extra-nodal disease (n = 4) or B symptoms at relapse (n = 4). The first cycle consisted of melphalan (150 mg/m(2)) alone. The second cycle consisted of fractionated total body irradiation (FTBI) 1200 cGy or BCNU (450 mg/m(2)) in combination with etoposide (60 mg/kg) and cyclophosphamide (100 mg/kg). Of the 46 patients, 5 (11%) did not receive the planned tandem transplants because of inadequate stem cell collection for 2 ASCT. After a median of 64 days (25-105), 41 patients received the second ASCT. With a median follow-up of 5.3 years (1.6-8.1), the 5-year estimate of overall survival, progression-free survival, and freedom from progression were 54% (95% confidence interval [CI] 40%-69%), 49% (95% CI, 34%-63%), and 55% (95%CI, 40%-70%), respectively. Our mature results from this study suggest that in patients with primary progressive or poor risk recurrent HL, this tandem ASCT program is effective and well tolerated and compares favorably with the conventional single transplant.
