Abstract Abstract 3559 Introduction. Myeloablative high dose chemotherapy (HDT) followed by single autologous stem cell transplantation is currently the standard treatment for patients younger than 65 years in newly diagnosed multiple myeloma (MM). Several randomized controlled trials (RCTs) comparing HDT with standard dose therapy (SDT) have shown some benefit in overall survival (OS) and progression free survival (PFS), whereas other RCTs did not confirm this finding. Koreth et al. (2007) performed a metaanalysis summarizing the existing data of the RCTs including 2,411 patients. These authors found a significant superiority for HDT in PFS but not in OS. Since a number of new studies have been published recently, we attempted to re-analyze the current data in terms of the endpoints OS and PFS. Methods. We searched PubMed, Embase, abstracts of former ASH meetings and ClinicalTrials.gov as well as bibliographies of included trials and recent reviews from september 2009 until may, 20th 2010. Amongst the 3,484 results in this search we identified 10 RCTs comparing HDT with SDT on an intent-to-treat-basis. Treatment characeristics and outcomes of OS and PFS were calculated using R. Furthermore, we tested for statistical heterogenity, publication bias and performed subgroup analyses. Results. 9 RCTs including 2,600 patients were fully analyzed. Patients undergoing HDT with stem cell transplantation did have significant PFS benefit (Hazard Ratio 0.73; 95% conficence intervall 0.56–0.95; P=0.02) but not OS benefit (HR 0.90; 95% CI 0.74–1.10; P=0.32) compared to patients undergoing SDT. Additional data from ongoing clinical trials are expected, thus updated results at the meeting including 10 RCTs with about 3,400 patients will be presented. Conclusion. Although there is only a trend to OS benefit with HDT, it is currently still the first line treatment. Additional data from ongoing clinical trials and new studies using novel agents like thalidomide, lenalidomide and bortezomib are egerly warrented to finally evaluate the role of HDT in the treatment management of patients with newly diagnosed MM. Disclosures: No relevant conflicts of interest to declare.

Abstract Introduction: Several treatment programs are available for the initial management of patients with multiple myeloma, with no clear documented advantage(s) of one regimen over the others in terms of time to progression (TTP) or overall survival (OS). Materials and Methods: A questionnaire was mailed to 540 randomly selected members of ASH during early 2005. Practitioners were asked their choice of therapy for newly diagnosed myeloma patients during 2004, based on 2005 NCCN guidelines, including: 1) melphalan/prednisone (MP), 2) vincristine / adriamycin / decadron (VAD), 3) high-dose decadron (HD), 4) thalidomide / decadron (Thal/Dex), 5) doxyl / vincristine / decadron (DVD); the options of a clinical trial (CT) or “other” were also included. Physicians were asked about factors influencing their choice of therapy for individual patients and their recommendations for autologous stem cell transplantation as part of the initial treatment schema. Results: Surveys were returned by 123 physicians(19.2%), of which 93 contained evaluable data. Among responders, 52% were in private practice and 47% in academic institutions and 74% respondants reporting having been in practice for more than 10 years. A large majority of physicians (74%) utilized 3 or more different regimens, only 10.7% of responders used a single regimen for all of their patients. Thal/Dex was used by 87% of responders, with 47% of them recommending this regimen in ≥ 50% of their patients. MP, HD and VAD were used by 67.7%, 49% and 44% of responders, but only 10.7%, 4% and 3% respectively, recommended them to ≥ 50% of their patients. DVD was used by 25% of physicians. Of respondants, 64.5% did not accrued patients to clinical trials and only 7.5% of physicians accrued ≥ 50% of their patients to clinical trials. No significant differences in the choice of regimen were apparent based on years of practice. Physicians in academic centers tended to use HD (p =.002) and accrue patients to CT (p=. 001) more often than those in private practice. Factors identified as important in selecting initial therapy for individual patients included: age (92%); performance status (95%); prognostic factors, such as β2-microglobulin and cytogenetics (75%); and candidacy for stem cell transplantation (93%). Respondants consider autologous stem cell transplantation as part of the initial therapy for all eligible patients (47%), only those with responsive disease (42%) and normal renal function (30%); only in selected cases (76%). Conclusions: Thal/Dex appears to be currently the most commonly recommended up-front therapy for multiple myeloma in the USA, in spite of the lack of published data documenting patient benefit in terms of TTP and OS. A sizable proportion of physicians do not recommend autologous stem cell transplantation as part of the initial therapy of newly diagnosed myeloma patients despite confirmed randomized clinical trials documenting benefit.

Abstract Introduction Effective reduction of myeloma before autologous stem cell transplantation (ASCT) prolongs survival in multiple myeloma patients. Recently, incorporation of novel agents resulted in improved response rate and reduced side effect in newly diagnosed multiple myeloma. Method: Patients are planned to receive 2 cycles of VAD (vincristine 0.4mg D1-4, adriamycin 9mg/m2 D1-4, dexamethasone 40mg D1-4, 9–12 every 3 weeks), and VTD (bortezomib 1.3mg/m2 D1, 4, 8, 11, thalidomide 100mg daily, dexamethasone 40mg D1-4, 9–12 every 3 weeks). High dose melphalan (200mg/m2) is used as a conditioning regimen for ASCT. Bortezomib (1.3mg/m2) as a maintenance treatment is administered weekly x 4 times every 6 weeks for 4 cycles after ASCT. Response was assessed by EBMT criteria, with additional category of nCR. Adverse events were graded by the NCI-CTCAE, Version 3.0. Result: At this interim analysis, 60 patients have been entered into the ongoing trial, and efficacy could be assessed in 53 patients. After 2 cycles of VAD, response rate was 70%. After VTD, two patients showed further improvement with additional CR, and an overall response was 97% with 14% CR. Especially, patients with poor prognostic cytogenetics (n=6) all responded after VTD. So far, autologous stem cells were successfully collected in all 28 patients with a median CD34+ count of 7.8 x 106/kg (range, 2.17–44.7 x 106/kg). In 24 patients who underwent autologous stem cell transplantation, five patients gained additional CR. There was no progression in patients completed bortezomib maintenance (n=9, CR 77%). The median follow-up duration was 6 months, median time to response was 1.4 months, and median overall survival was not reached. Grade 3,4 hematologic toxicity was more frequently observed after VAD than VTD (anemia 15.8%, 4.6%, neutropenia 7.9%, 3.5%), and incidence of grade 2,3 peripheral neuropathy was low (VAD 3.5%, VTD 7%). Conclusion: Sequential VAD and VTD induction therapy in newly diagnosed multiple myeloma was highly effective, even in patients with poor prognostic cytogenetics, and did not prejudice stem cell collection. VTD could have contributed to increased RR and minimized side effects. An updated results will be presented at the ASH meeting. *Protocol Number: KMM51-NCT00378755.

Background: The use of novel agents for induction prior to autologous stem cell transplantation (ASCT) has considerably improved the complete response (CR) rate in multiple myeloma (MM) patients. There are very few studies from the developing countries on the use of novel agents followed by ASCT.Aims and Objectives: The current study was aimed for retrospective evaluation of the efficacy and response rates of induction with bortezomib (Velcade) plus dexamethasone (VD regimen) followed by ASCT in Indian patients.Materials and Methods: Ten patients with newly diagnosed, symptomatic MM who had received four cycles of VD induction before stem cell collection were evaluated. High dose melphalan was given for conditioning followed by stem cell transfusion. Thalidomide or lenalidomide was used as post-transplantation maintenance treatment.Results: Post VD induction, the overall response rate (ORR) was 90% including 20% CR, 40% very good partial response (VGPR), and 30% partial response (PR). Post ASCT, the ORR was 100%, including 80% CR and 20% VGPR. The 5-year overall survival and progression free survival rates were 65.6% and 57.1%, respectively.Conclusions: The VD induction regimen was effective and well tolerated in this retrospective analysis of Indian patients with newly diagnosed MM. It significantly improved the post-induction and post-transplant response rates without affecting stem cell collection.Asian Journal of Medical Sciences Vol.7(4) 2016 44-48
