Summary of "Modified BuCy is an alternative conditioning regimen for lymphoma patients undergoing autologous stem cell transplantation."

The aim of this study is to determine whether the modified BuCy (semustine, cytarabine, busulfan, and cyclophosphamide, mBuCy) conditioning regimen can be safely used as an alternative to the SEAM (semustine, etoposide, cytarabine, and melphalan) regimen by comparing the efficacy and toxicity of the mBuCy and SEAM regimens. We matched 34 pairs of patients with regard to disease status at the time of autologous stem cell transplantation (auto-SCT). We found no significant difference in the time of platelet engraftment between the two groups. Furthermore, neutrophil engraftment was somewhat faster in the mBuCy group than in the SEAM group (median: 9 days vs 10 days, p = 0.015). With regard to toxicity, the incidence of nausea/vomiting, hepatic impairment, renal impairment, pulmonary infection, and treatment-related mortality (TRM) was similar between the two groups. In addition, compared to patients conditioned with SEAM, patients conditioned with mBuCy were less likely to develop mucositis and diarrhea (p = 0.027; p = 0.050). The 2-year progression-free survival (PFS) rates in the mBuCy and SEAM groups were 79% and 70% (p = 0.378), respectively, and the 2-year overall survival (OS) rates were 81% and 78.0%, respectively (p = 0.789). These analyses showed that the mBuCy conditioning regimen was well tolerated and can be used as an alternative to the SEAM regimen for lymphoma.

Medical and Biotech [MESH] Definitions

B-cell lymphoid tumors that occur in association with AIDS. Patients often present with an advanced stage of disease and highly malignant subtypes including BURKITT LYMPHOMA; IMMUNOBLASTIC LARGE-CELL LYMPHOMA; PRIMARY EFFUSION LYMPHOMA; and DIFFUSE, LARGE B-CELL, LYMPHOMA. The tumors are often disseminated in unusual extranodal sites and chromosomal abnormalities are frequently present. It is likely that polyclonal B-cell lymphoproliferation in AIDS is a complex result of EBV infection, HIV antigenic stimulation, and T-cell-dependent HIV activation.

Preparative treatment of transplant recipient with various conditioning regimens including radiation, immune sera, chemotherapy, and/or immunosuppressive agents, prior to transplantation. Transplantation conditioning is very common before bone marrow transplantation.

A strain of PRIMATE T-LYMPHOTROPIC VIRUS 1 isolated from mature T4 cells in patients with T-lymphoproliferation malignancies. It causes adult T-cell leukemia (LEUKEMIA-LYMPHOMA, T-CELL, ACUTE, HTLV-I-ASSOCIATED), T-cell lymphoma (LYMPHOMA, T-CELL), and is involved in mycosis fungoides, SEZARY SYNDROME and tropical spastic paraparesis (PARAPARESIS, TROPICAL SPASTIC).

Reflex closure of the eyelid occurring as a result of classical conditioning.

A hematopoietic growth factor which promotes proliferation and maturation of neutrophil granulocytes. Clinically it is effective in decreasing the incidence of febrile neutropenia in patients with non-myeloid malignancies receiving myelosuppressive therapy or in reducing the duration of neutropenia and neutropenia-related clinical sequelae in patients with non-myeloid malignancies undergoing myeloblastive chemotherapy followed by BMT. It has also been used in AIDS patients with CMV retinitis being treated with GANCICLOVIR. (Gelman CR, Rumack BH & Hess AJ (eds): DRUGDEX(R) System.
