98 patients with relapsed myeloma underwent a second autologous transplant as salvage strategy. Transplant-related mortaity was 4%. Median progression-free survival after the second stem cell transplant was 10 months. Shorter PFS was predicted by:
- Higher number of previous treatment regimens
- Failure to achieve complete remission after the second transplant
- Shorter remission after the first transplant

Kukreti V, Masih-Khan E, Young T, Chu CM, Jiang H, Trudel S, Chen C, Jimenez-Zepeda V, Reece DE.
This retrospective study of 24 patients with myeloma refractory to lenalidomide (or intolerant to lenalidomide) received salvage treatment with thalidomide. Response rate was 38% (all VGPR or PR, no CR), and median progression-free survival was only 3 months.

This phase I study identified the maximum dose for CRD:
- Carfilzomib 27 mg/m2 IV on days 1,2, 8,9, 15,16
- Revlimid 25 mg PO on days 1-21
- Dexamethasone 40 mg PO weekly
Cycles were repeated every 28 days. Response rate was 62.5%, and median progression-free survival was 10 months.

In this study of translocation analysis in 61 myeloma samples, the authors found that 100% of the t(4;14) translocations were mediated by class switch recombination in mature B cells in the germinal center. Unexpectedly, 21% of the t(11;14) and 25% of the t(14;20) were generated during the DH-JH recombination in pro-B-cells in the bone marrow.
Serum free light
chain ratio as a biomarker for high-risk smoldering multiple myeloma.

Larsen JT, Kumar SK, Dispenzieri A, Kyle RA, Katzmann JA, Rajkumar SV.
After a retrospective review of 5865 patients with smoldering myeloma seen at the Mayo Clinic between 1970 and 2010, the authors found that a serum involved/uninvolved FLC ratio >100 (seen in 15% of cases) had a 98% chance to progress to symptomatic myeloma within a median follow-up of 52 months (vs 56% in all patients), and a 72% risk of progressing to symptomatic myeloma within 2 years.
injection of bortezomib, melphalan and dexamethasone in refractory and relapsed

Romano A, Chiarenza A, Consoli U, Conticello C, Forte S, Uccello G, Vetro C, Cavalli M, Coppolino F, Palumbo GA, Di Raimondo F.
50 patients with previously treated myeloma received Mel-Dex-Vel. Most patients received all 3 drugs once a week:
- Melphalan 5 mg/m2 IV
- Dexamethasone 40 mg IV
- Bortezomib 1.3 mg/m2 IV
Response rate was 62%, and median progression-free survival was 22 months. Toxicity was acceptable.

Fifty-three patients with relapsed/refractory myeloma were treated with siltuximab +/- dexamethasone. Single-agent siltuximab was ineffective (no responses), and combination therapy with siltuximab + dexamethasone had a modest effect: RR was 17% (partial responses), and median progression-free survival was 3.7 months.

This study reports the outcomes of 187 patients who underwent a second autologous stem cell transplant for relapsed/refractory myeloma. Patients previously treated with tandem transplants were excluded from the analysis. Median interval between the first SCT and relapse/progression of myeloma was 18 months, and median interval between the first transplant and the second one was 32 months. At 3 years, progression-free survival was 13%, and overall survival was 46%. As expected, the benefit of the second SCT done as salvage therapy was greater in those patients who experienced a longer (>36 months) period of disease remission after the first SCT.

The authors report the presence of typical MYD88 L265P exon 5 mutations in 6 of 7 patients with Waldenstrom macroglobulinemia, and in 0 of 4 patients with IgM myeloma. They conclude that the MYD88 mutational status may be useful for discriminating between WM and IgM-MM.

neoplasms in US solid organ transplant recipients.

Engels EA, Clarke CA, Pfeiffer RM, Lynch CF, Weisenburger DD, Gibson TM, Landgren O, Morton LM.
Among 202,600 solid organ transplant recipients, 140 patients developed plasma cell neoplasms (102 cases of myeloma and 38 cases of plasmacytomas). Although the risk was 1.8-fold increased relative to the general population (95% CI 1.5-2.1), I am not particularly impressed by the frequency: only 1 case of myeloma in 1986 transplanted patients.

This is a study of 196 consecutive myeloma patients treated with a stem cell transplant from unrelated donors, between 2000 and 2009. The long-term results were disappointing, because the median event-free survival was:
- 10 months with myeloablative regimens (OS 29 months)
- 6 months with reduced-intensity regimens (OS 11 months)
- 13 months with nonmyeloablative regimens (OS 32 months)

This is a retrospective study of 75 patients with relapsed/refractory myeloma treated with D(T)-PACE chemotherapy. Overall response rate was 49% (PR 33%, VGPR 16%). The duration of remission was short, because median progression-free survival was 5.5 months. Median OS was 14 months.

This is a study of 370 myeloma patients treated with an autologous stem cell transplant and randomized to consolidation with 21 weeks of bortezomib vs no consolidation. Bortezomib improved progression-free survival (27 vs 20 months) but not overall survival. Consolidation with bortezomib did not seem to be beneficial for those patients who reached at least a VGPR after the transplant.
