A Retrospective Comparison of TECAM and BEAM Conditioning Regimens Before Autologous Hematopoietic Stem Cell Transplant in Lymphoma Patients: Efficacy and Toxicity.

OBJECTIVES: The aim of our study was to evaluate the efficacy and toxicity of TECAM (thiotepa, etoposide, cyclophosphamide, cytarabine, and melphalan) and BEAM (carmustine, etoposide, cytarabine, and melphalan) conditioning regimens before autologous hematopoietic stem cell transplant in patients with lymphoma.

MATERIALS AND METHODS: We retrospectively analyzed 108 relapsed/refractory lymphoma patients who had high-dose treatments followed by autologous hematopoietic stem cell transplant between October 2012 and February 2017.

RESULTS: At a median follow-up period of 16 months, the estimated 2-year progression-free survival rates for the TECAM and BEAM groups were 55.7% and 52.9%, respectively (P = .811). The estimated 2-year overall survival rate in the TECAM group (55.9%) was relatively inferior to that shown in the BEAM group (67%), but the differences were not significant (P = .238). No differences were observed for time to hematopoietic recovery and duration of hospitalization. Incidences of transplant-related infectious and noninfectious complications were similar for each conditioning regimen.

CONCLUSIONS: Our experience shows that the TECAM regimen is an effective high-dose chemotherapy for lymphoma patients before autologous hematopoietic stem cell transplant.
