Second autologous transplantation after failure of a first autologous transplant in 18 patients with non-Hodgkin's lymphoma.

High-dose chemotherapy and autologous marrow or peripheral stem cell support offers the best chance of cure in some subgroups of patients with non-Hodgkin's lymphoma (NHL). Less is known about the role of a second course of myeloablative chemotherapy in patients who relapse after a first autologous transplant. The aim of this retrospective study was to evaluate the disease outcome, morbidity and mortality associated with second autologous transplantation in patients with NHL. Between 1985 and 2001, 225 patients who had received autologous transplantation for NHL in two institutions in Lyon relapsed. Of these 225 patients 18 underwent a second autologous transplantation. The median age at second transplant was 41 years. There were six indolent lymphomas and 12 aggressive lymphomas. The median follow-up from the second transplant was 42 months. The OS rate at 2 and 5 years were 58 and 27%, respectively. The PFS rate at 2 and 5 years was 36%. Five patients are alive without disease 20 to 100 months after the second transplant. Seven patients died of disease recurrence. Four (22%) toxic deaths occurred: one of pulmonary fibrosis, one of fungal infection and cardiac failure and two of acute leukaemia. A minority of patients with NHL recurrence after a first transplant can be cured by a second course of myeloablative chemotherapy at the cost however of high-risk toxic death.
