Abstract Abstract 1090 Background: The incidence of venous thromboembolism (VTE) in patients with multiple myeloma (MM) is high in patients treated with thalidomide (T)- and lenalidomide (L)-based regimens containing dexamethasone (D) and/or cytotoxic chemotherapy (C). Consensus guidelines recommend routine thromboprophylaxis but reliable data from randomized controlled trials are lacking. Recent observational studies have suggested that thromboprophylaxis might be efficacious in decreasing the risk of VTE in this population. Purpose: To determine the absolute rates of VTE with and without different thromboprophylactic agents (ASA, warfarin, low-molecular-weight-heparin [LMWH]) in patients with newly diagnosed or previously treated MM receiving T- or L-based regimens. Data Source: A systematic literature search strategy was conducted using MEDLINE, EMBASE, the Cochrane Register of Controlled Trials and all EBM Reviews of published studies up to Jan 2010. Results: A total of 66 studies were included in the analyses. Of these, 61 (4264 patients) and 5 (1119 patients) assessed T- and L-based regimens, respectively. Thalidomide-based regimens The rates of VTE (per 100 patient-cycles) in patients with newly diagnosed MM treated with T-based regimens: The rates of VTE (per 100 patient-months) in patients with previously treated MM managed with T-based regimens: Lenalidomide-based regimens The rates of VTE (per 100 patient-cycles) in patients with newly diagnosed MM treated with L-based regimens: The rate VTE (per 100 patient-months) in patients with previously treated MM managed with L-based regimens: None of the studies reported major bleeding events. Limitations: The definition for VTE varied across studies. Most studies did not outline the diagnostic criteria for VTE. Data are not available (NA) for all prophylaxis regimens. Conclusion: Patients with newly diagnosed or previously treated MM receiving T- or L-based regimens are at high risk of VTE. It is uncertain whether thromboprophylaxis provides a clear benefit, especially in those receiving L-based therapy or have previously treated disease. Randomized controlled trials are needed to address this important clinical need.

The Impact

Abstract Abstract 615 Background: Trials comparing efficacy of standard melphalan prednisone (MP) therapy with MP plus thalidomide (T) in the transplant ineligible, elderly patients with multiple myeloma have provided conflicting evidence. While there is greater agreement with regard to superior response rates (RR) with the addition of T to MP in elderly patients, the impact on progression free survival (PFS) and overall survival (OS) is less clear with some trials showing an improvement in PFS and/or OS with MPT and others demonstrating no difference in outcomes. We performed a systematic review to integrate the existing outcome data related to the efficacy of MP vs. MPT using a meta-analytic approach. Methods: A comprehensive search of electronic database through July 31st, 2009 was performed for publications, abstracts and presentations to identify randomized controlled trials (RCTs) comparing MP with MPT. A meta-analysis was performed by pooling results on clinical endpoints of RR, PFS and OS reported in all the identified RCTs under a random effects model. We did not have access to individual patient data from these trials. Results: Overall, five prospective RCTs (3 published articles and 2 abstracts) comparing MP with MPT regimen and comprising a total of 1571 patients were identified. For the endpoints of OS and PFS, data were extractable only from 4 RCTs (abstract by Gulbrandsen et al. was excluded). The Bregg and Egger funnel plot for OS demonstrated a symmetric distribution (P = 0.6) indicating no significant publication bias. The test of heterogeneity among all RCTs was statistically significant in the estimate of RR (tau2=0.21; chi2=16.33; p=0.003 (df=4); I2 = 75.5%), but not significant for the estimates of PFS (tau2=0.01; chi2=4.61; p=0.2 (df=3); I2 = 34.9%), and OS (tau2=0.02; chi2=5.53; p=0.14 (df=3); I2 = 45.8%). As expected, the pooled odds ratio of responding to treatment with MP versus MPT was 0.307 (P<0.001) indicating that MP was worse than MPT in achieving at least a partial response. The pooled hazard ratios (HR) for PFS and OS were 1.59 (p<0.001) and 1.34 (p=0.006), respectively (see table for forest plots) in favor of MPT. Conclusion: Our meta-analysis implies that in previously untreated, transplant ineligible elderly patients with multiple myeloma, the addition of thalidomide to melphalan-prednisone demonstrates improved RR, PFS and OS compared with the use of melphalan-prednisone alone. Although the results from a comprehensive individual patient data pooled analysis would give a more precise estimate, our analysis suggests that MPT is superior to MP in terms of response and survival.
