Abstract

OBJECTIVES:

A BEAM regimen including carmustine (BiCNU: bis-chloroethyl nitrosourea), etoposide, cytarabine (cytosine arabinoside), and melphalan is a widely used conditioning regimen for autologous stem cell transplant in patients with Hodgkin lymphoma. We report the results of noncryopreserved autologous stem cell transplant of 45 patients with Hodgkin lymphoma given an alternative regimen, modified BEAM-like regimen (CEAM regimen: lomustine, etoposide, cytarabine, and melphalan), in which carmustine (BiCNU IV) was substituted by oral lomustine (CCNU: 2 chloroethyl cyclohexyl nitrosourea).

PATIENTS AND METHODS:

Forty-five eligible patients with relapsed/refractory Hodgkin lymphoma were consecutively enrolled and underwent conditioning regimen with BEAM-like regimen protocol as follows: Lomustine 200 mg/m(2) on day -3; etoposide 1000 mg/m(2) on day -3 and -2; cytarabine 1000 mg/m(2) on days -3, -2; and Melphalan 140 mg/m(2) on day -1.

RESULTS:

All 45 patients showed engraftment of infused stem cell, and there was no graft failure in the study group. The median mononuclear cell dose was 3.4 × 10(8). The median time to absolute neutrophil count > 0.5 × 10(9)/L was 11 days, and the median time to platelet count > 20 × 10(9) was 14 days. Grade 2 and grade 3 mucositis was seen in 64.5% our patients. Transplant-related mortality at 100 days occurred in 1 patient (2.2%). With a median follow-up of 27 months, median disease-free survival was 20 months, mean overall survival was 27 months, and median overall survival has not yet been reached.

CONCLUSIONS:

These data demonstrate the safety and feasibility of BEAM-like regimen as a new and modified regimen; longer follow-up is required to evaluate fully efficacy and long-term safety of our method.
