- The outcome for multiple myeloma patients has improved since the introduction of bortezomib, thalidomide and lenalidomide. However, studies comparing new and conventional treatment include selected patient groups. We investigated consecutive patients (n = 1638) diagnosed in a defined period and compared survival with a gender- and age-matched cohort Swedish population (n = 9 340 682). Median overall survival for non-high-dose treated patients was 2.8 years. The use of bortezomib, thalidomide or lenalidomide in first line therapy predicted a significantly longer overall survival (median 4.9 years) compared to conventional treatment (2.3 years). Among non-high-dose treated patients receiving at least 2 lines with bortezomib, thalidomide or lenalidomide, 69% and 63% have survived at 3 and 5 years as compared to 48% and 22% with conventional drugs and 88% and 79% in the matched cohort populations, respectively. The median overall survival in high-dose treated patients was 6.9 years. Of these patients, 84% survived at 3 years and 70% at 5 years as compared to 98% and 95% in the matched cohort population. Overall survival in the best non-high-dose treated outcome group is closing the gap with the matched cohort. Upfront use of new drugs is clearly better than waiting until later lines of treatment.

- The combination of melphalan and prednisone (MP) has been the standard treatment of multiple myeloma (MM). Since the introduction of novel agents, the clinical outcome in MM has improved. Several prospective studies with thalidomide combined with MP (MPT) compared to MP have been performed, most of them showing that MPT gives a better response rate and median overall survival (OS). Among 1843 MM patients admitted to 15 Swedish centres, we selected all patients treated with MP and MPT in 1(st) , 2(nd) , 3(rd) or 4(th) line of therapy, in total 888 patients treated with MP and 274 with MPT. Patients were evaluated for response rate, OS and TTNT. Multivariate Cox model analysis was made to adjust for different criteria at time for MM-diagnosis. The median OS from beginning of 1(st) line of treatment was 2.2/4.2 years after MP/MPT respectively, and in 2(nd) , 3(rd) and 4(th) line of treatment 1.8/2.9, 1.4/1.6 and 1.1/1.9 years (P<0.0001, 0.003, 0.74 and 0.235). The relative risk for death in the MPT group vs. the MP group was 0.61 (95% CI: 0.45-0.84) in 1(st) and 0.55 (0.38-0.83), p<0.01) in 2(nd) line. Treatment with MPT gave a significantly better overall survival rate after both 1(st) and 2(nd) line of therapy compared to treatment with MP only. This article is protected by copyright.

- Background: Induction therapy for multiple myeloma (MM) and remission status before high-dose treatment (HDT) have been shown to be prognostic factors for survival outcome, although the optimal induction therapy is yet to be defined. Methods: We conducted a retrospective analysis of the impact of induction therapy on survival outcome before and after HDT in MM patients. The study included 236 consecutive patients who underwent HDT. Results: One hundred and forty-two patients (62%) were treated with vincristine, doxorubicin and dexamethasone (VAD) or cyclophosphamide and betamethasone (CyBet) and 94 (38%) were treated with bortezomib, cyclophosphamide and betamethasone (VCB) as induction. Time to first and time to best response was faster in the VCB group than in the VAD/CyBet group, with 42 versus 75 (p < 0.001) and 54 versus 88 days (p < 0.001), respectively. After induction therapy, 49% of the patients in the VCB group and 38% in the VAD/CyBet group achieved a very good partial response or better. Multivariate analysis revealed younger age, lower International Staging System stage and induction treatment with VCB as variables associated with favourable time to progression. Conclusions:Outcome measured as response and time to progression before and after HDT in MM differs depending on type of induction treatment and suggests that VCB is a highly effective induction regimen that confers a post-HDT advantage.
