| Abstract | The efficacy and safety of thalidomide as an initial treatment in myeloma patients who were unsuitable for autologous stem cell transplantation (ASCT), as induction treatment prior to ASCT, or as a maintenance treatment was unclear. The purpose of this study was to assess the benefits and risks of thalidomide for previously untreated myeloma patients. MEDLINE, EMBASE, and Cochrane Library were searched for randomized controlled trials (RCTs) of thalidomide used in either induction or maintenance therapy for previously untreated myeloma patients. Twenty-two RCTs enrolling 9098 patients were identified, including 15 RCTs of induction thalidomide, 6 RCTs of maintenance thalidomide, and 1 RCT of induction and maintenance thalidomide. Induction thalidomide improved overall response rate (ORR) (risk ratio (RR) 1.54, 95 % confidence interval (CI) 1.30–1.83), complete response rate (CRR) (RR 3.03, 95 % CI 1.91–4.80), progression-free survival (PFS) (hazard ratio (HR) 0.65, 95 % CI 0.56–0.76), and overall survival (OS) (HR 0.78, 95 % CI 0.67–0.91) in patients who were not allowed to receive ASCT. Induction thalidomide improved pre-ASCT ORR (RR 1.20, 95 % CI 1.11–1.30), pre-ASCT and post-ASCT CRR (RR 1.47, 95 % CI 1.12–1.93 and RR 1.23, 95 % CI 1.00–1.50, respectively), and PFS (HR 0.73, 95 % CI 0.59–0.91) in patients who were allowed to receive ASCT, but it did not improve post-ASCT ORR (RR 1.04, 95 % CI 0.99–1.09) and OS (HR 0.91, 95 % CI 0.79–1.05). Improved PFS and prolonged OS were observed (HR 0.61, 95 % CI 0.53–0.70 and HR 0.77, 95 % CI 0.62–0.95, respectively) when thalidomide was added to maintenance therapy. More patients experienced venous thromboembolism (VTE) of grade 3/4 when thalidomide was added to induction or maintenance therapy (HR 2.15, 95 % CI 1.58–2.92 and RR 1.96, 95 % CI 1.13–3.40, respectively). Induction thalidomide still increased the risk of VTE (RR 1.53, 95 % CI 1.12–2.08) after VTE prophylaxis was used. Induction thalidomide effectively improved CRR, ORR, and PFS (except post-ASCT ORR). Notably, induction thalidomide improved OS in patients who were not allowed to receive ASCT but not in patients who were allowed to receive ASCT. The addition of thalidomide to maintenance therapy improved both PFS and OS. However, thalidomide led to a greater risk of VTE with grade 3/4. This risk did not disappear after VTE prophylaxis was used in induction therapy with thalidomide. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
