CLINICAL TRIALS AND OBSERVATIONS Myeloma in patients younger than age 50 years presents with more favorable features and shows better survival: an analysis of 10 549 patients from the International Myeloma Working Group1 Department of Medicine, Wilhelminenspital, Vienna, Austria; 2 Southwest Oncology Group, International Myeloma Foundation and Cedars Sinai Comprehensive Cancer Center, Los Angeles, CA; 3 Cancer Research and Biostatistics, Seattle, WA; 4 Department of Hematology, University Hospital, Malmö, Sweden; 5 Division of Hematology, Mayo Clinic, Rochester, MN; 6 Hematology Department, Institute of Hematology and Oncology, Hospital Clinic, Institut d' Investigacious Biomediques August Pi i Sunyer, Barcelona, Spain; 7 Division of Hematology and Oncology, Mayo Clinic Comprehensive Cancer Center, Scottsdale, AZ; 8 Department of Clinical Therapeutics, University of Athens School of Medicine, Athens, Greece; 9 Department of Medicine, Nagoya City Midori General Hospital, Nagoya, Japan; 10 University Hospital of Salamanca, Salamanca, Spain; 11 Department of Hematology, University Hospital, Lund, Sweden; 12 Division of Hematology, Centre Hospitalier Universitaire Hotel-Dieu, Nantes, France; 13 Department of Microbiology and Clinical Microbiology, Ankara University School of Medicine, Ibn-i Sina Hospital, Ankara, Turkey; 14 Divisione Universitaria di Ematologia, Ospedale Molinette, Torino, Italy; 15 Myeloma Institute for Research and Therapy, University of Arkansas for Medical Sciences, Little Rock, AR; 16 Department of Medicine, McGill University, Montreal, QC; 17 Institute of Hematology and Medical Oncology Seragnoli, University of Bologna, Bologna, Italy; 18 Institute of Haematology, Royal Prince Alfred Hospital, Sydney, New South Wales, Australia; 19 Service d'Hématologie, Hôpital Purpan, Toulouse, France; and 20 Department of Hematology, Erasmus MC, Rotterdam, The Netherlands We analyzed the presenting features and survival in 1689 patients with multiple myeloma aged younger than 50 years compared with 8860 patients 50 years of age and older. Of the total 10 549 patients, 7765 received conventional therapy and 2784 received high-dose therapy. Young patients were more frequently male, had more favorable features such as low International Staging System (ISS) and Durie-Salmon stage as well as less frequently adverse prognostic factors including high C-reactive protein (CRP), low hemoglobin, increased serum creatinine, and poor performance status. Survival was significantly longer in young patients (median, 5.2 years vs 3.7 years; P < .001) both after conventional (median, 4.5 years vs 3.3 years; P < .001) or high-dose therapy (median, 7.5 years vs 5.7 years; P = .04). The 10-year survival rate was 19% after conventional therapy and 43% after high-dose therapy in young patients, and 8% and 29%, respectively, in older patients. Multivariate analysis revealed age as an independent risk factor during conventional therapy, but not after autologous transplantation. A total of 5 of the 10 independent risk factors identified for conventional therapy were also relevant for autologous transplantation. After adjusting for normal mortality, lower ISS stage and other favorable prognostic features seem to account for the significantly longer survival of young patients with multiple myeloma with age remaining a risk factor during conventional therapy.
