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.
