Abstract

Purpose: To improve outcome in previously treated patients (at least two cycles of standard therapy) with multiple myeloma, thalidomide was combined with cytotoxic chemotherapy as induction therapy. Patients and Methods: The regimen consisted of 4-days of oral dexamethasone, daily thalidomide/and 4 days of continuous-infusion cisplatin, doxorubicin, cyclophosphamide, and etoposide (DTPACE). Response to two cycles of DTPACE for induction was evaluated in 236 patients. Before being treated with DTPACE, 148 patients (63%) had shown progressive disease while receiving standard chemotherapy, and 55 patients (23%) had chromosome 13 abnormalities. Results: The partial remission rate (PR) after two cycles of DTPACE was 32%, with 16% attaining a complete remission (CR) or near-CR (nCR; defined as only immunofixation electrophoresis-positive). Patients with high lactate dehydrogenase (LDH; n = 98) showed a better response than those with normal LDH (n = 138): PR or better, 43% v 27% (P = .01); CR + nCR, 25% v 11% (P = .01). Patients with chromosome 13 abnormalities (n = 55) responded equally well as the other patients (n = 181): PR or better, 35% v 33% (P = .84); CR + nCR, 17% v 15% (P = .73). Patients who received 100% dose of DTPACE for two cycles (n = 115) achieved higher response rates than those with less than 100% dose (n = 121): PR or better, 49% v 17% (P < .0001); CR + nCR, 27% v 6% (P < .0001). Conclusion: Combination therapy of oral dexamethasone and thalidomide with infusional chemotherapy is effective as induction therapy before autotransplantation, especially in patients with high-risk features.
