Abstract
BACKGROUND Multiple myeloma (MM) represents the second most common hematologic malignancy (15%). Induction with bortezomib, cyclophosphamide, and dexamthasone VCd (d: low dose dexamthasone) regimen is widely used due to its high effectiveness, low toxicity and good tolerability, particularly with renal impairment. Real-world data on the use of VCD in clinical practice is lacking. OBJECTIVES Evaluate the real-world experience of the VCD regimen. DESIGN Retrospective. SETTING Tumor registry database of tertiary cancer care center. PATIENTS AND METHODS newly diagnosed MM patients who received VCD induction and underwent autologous stem cell transplant (ASCT) from July 2007 to July 2020. MAIN OUTCOME MEASURES response evaluation, progression-free survival (PFS) and overall survival (OS). SAMPLE SIZE 87 patients. RESULTS Of 102 patients who started induction with VCd, 87 patients experienced a partial response or more overall response rate of 85%). The median age of these 87 patients at diagnosis was 52 years, of which 29.9% presented with renal impairment and 60.3% of patients had stage 2 by the Revised International Staging System (R-ISS). Patients with a standard cytogenetic risk achieved a better response compared to those with a poor cytogenetic risk (P=.044). The post-induction response rates were 6.9% stringent complete remission (sCR), 35% complete remission (CR); 41.4% very good partial response (VGPR), and 16.1% partial response (PR), respectively; the response rates became greater for sCR and CR post-transplantation at day 100 with 16.1% sCR, 35.6% CR, 32.2% VGPR and 16.1% PR, respectively. The median PFS was 49 months and 5 years OS was 84%. PFS was better in patients who achieved sCR vs PR (83 vs 35 months, P=.037). High LDH, high-risk cytogenetic and stage 3 R-ISS showed a worse median PFS and OS. CONCLUSIONS VCD induction in newly diagnosed MM is highly effective, convenient, tolerable and affordable regimen, especially in low and middle-income countries with limited resources, also with favorable outcomes and survival. while those who did not respond successfully shifted to VRD or VTD. LIMITATIONS The usual limitations of a retrospective analysis using registry-level data, no data on quality of life.
