High dose chemoradiotherapy with autologous hematopoietic stem cell transplantation in the treatment of advanced Hodgkin’s lymphoma: A report of 11 cases

Abstract

Objective: High dose therapy (HDT) with autologous hematopoietic stem cell transplantation (ASCT) has become one of the important salvage treatments for the Hodgkin’s Lymphoma patients with relapsed or resistant disease, but its role as the primary treatment remains indefinite. This study was designed to further evaluate its status in the combined modality treatment, especially, to discuss its value in the primary treatment of the patients who had advanced disease with poor prognostic factors. Methods: Eleven patients who had advanced or relapsed disease with poor prognostic factors were enrolled in this study. Among them, 9 cases had primary treatment, and 2 cases had secondary treatment; one patient received autologous bone marrow transplantation (ABMT), and 10 patients received autologous peripheral blood stem cell transplantation (APBSCT). After induction treatment 4 cases achieved complete response (CR) and 7 cases achieved partial response (PR). High dose chemotherapy combined with total body irradiation (TBI) or total lymph node irradiation (TLI)/subtotal lymph node irradiation (STLI) were adopted in 7 cases and only high dose chemotherapy were adopted in 4 cases as the transplant preparative regimens. 5 cases received complementary irradiation in the primary sites after transplant. Results: The patients who had CR before transplantation were given consolidative therapy. Among the rest with PR, 2 cases achieved CR, 1 case PR, and 4 cases SD. Furthermore all these patients who maintained SD had bone involvement. With a median follow-up for all patients of 13(1–80) months, all of them are alive currently. Four cases are event-free survival (EFS); 4 cases with bone involvement are progression-free survival (PFS); 3 cases experienced relapse after transplant, one of them is EFS for 42 months again after a local relapsed site irradiation; the other two cases are being given further salvaged treatment now. According to the Life Tables method, the cumulative probability of 6-year PFS and OS is 55.68% and 100% respectively. The dominating transplant-related toxicity was bone marrow suppression in grades IV. No obvious cardiac, hepatic, and nephritic toxicity was found. No transplant related mortality. Conclusion: HDT combined with ASCT is a method worthwhile to further study for the treatment of the patients with advanced or relapsed Hodgkin’s Lymphoma with poor prognostic factors.
