The combination of cyclophosphomide, thalidomide and dexamethasone is an effective alternative to cyclophosphamide – vincristine – doxorubicin – methylprednisolone as induction chemotherapy prior to autologous transplantation for multiple myeloma: a case-matched analysis

Abstract

A retrospective case-matched study was conducted to compare the oral regimen CTD (cyclophosphamide - thalidomide - dexamethasone) and infusional CVAMP (cyclophosphamide - vincristine - doxorubicin - methylprednisolone) as induction therapy followed by autologous peripheral blood stem-cell transplantation (PBSCT) for newly diagnosed multiple myeloma patients. The response rate after three cycles of treatment was statistically higher with CTD (n = 27) compared to CVAMP (n = 27) (89% vs. 56%, P = 0.016). Toxicity studies showed more neutropenia (grade 3/4) (4% vs. 60%, P = 0.0002) with CVAMP and more thrombotic episodes with CTD (11% vs. 4%). CTD may emerge as the superior induction regimen prior to PBSCT, in terms of high efficacy and better tolerability.
