Patients with primary refractory Hodgkin's disease (PR-HD) have a dismal prognosis when treated with conventional salvage chemotherapy. We analyzed time to treatment failure (TTF), overall survival (OS) and clinical variables influencing the outcome in patients undergoing autologous stem cell transplantation (ASCT) for PR-HD and reported to the Grupo Español de Linfomas/Trasplante Autólogo de Médula Osea (GEL/TAMO).
PATIENTS AND METHODS
Sixty-two patients, 41 males and 21 females with a median age of 27 years (range 13-55) were analyzed. Forty-two patients (68%) had advanced stage at diagnosis, 47 (76%) presented with B symptoms and 29 (47%) with a bulky mediastinal mass. Seventy-five percent of the patients had received more than one line of therapy before ASCT. Thirty-three patients received bone marrow as a source of hematopoietic progenitors, and 29 peripheral blood. Six patients were conditioned with high-dose chemotherapy plus total-body irradiation and 56 received chemotherapy-based protocols.
One-year transplantation-related mortality was 14% [95% confidence interval (CI) 6% to 23%]. Response rate at 3 months after ASCT was 52% [complete remission in 21 patients (34%), partial remission in 11 patients (18%)]. Actuarial 5-year TTF and OS were 15% (95% CI 5% to 24%) and 26% (95% CI 13% to 39%), respectively. The presence of B symptoms at ASCT was the only adverse prognostic factor significantly influencing TTF [relative risk (RR) 1.75, 95% CI 0.92-3.35, P = 0.08]. The presence of B symptoms at diagnosis (RR 2.08, 95% CI 0.90-4.79, P = 0.08), MOPP-like regimens as first-line therapy (RR 3.84, 95% CI 1.69-9.09, P = 0.001), bulky disease at ASCT (RR 2.79, 95% CI 0.29-6.03, P = 0.009) and two or more lines of therapy before ASCT (RR 2.24, 95% CI 0.95-5.27, P = 0.06) adversely influenced OS.
In our experience, although overall results of ASCT in PR-HD patients are poor, one-quarter of the patients remain alive at 5 years. Despite this, other therapeutic strategies should be investigated in this group of patients to improve the outcome.
