This study analyzed clinical and laboratory data from 10,750 myeloma patients, and found a reliable staging system, simpler than the old Durie-Salmon system. Patients had newly diagnosed symptomatic multiple myeloma, and they were followed at 17 institutions from several sites, including North America, Europe, and Asia. Important prognostic factors were beta-2-microglobulin, albumin, platelet count, creatinine, and age, but the combination of beta-2-microglobulin and albumin provided the simplest and most powerful risk stratification. Median survival was 62 months in stage I (b2m <3.5 and albumin > or = 3.5), 44 months in stage II (neither stage I nor III), and 29 months in stage III (b2m > or = 5.5).
Overexpression of transcripts originating
from the MMSET locus characterizes all t(4;14)(p16;q32)-positive multiple

Keats JJ, Maxwell CA, Taylor BJ, Hendzel MJ, Chesi M, Bergsagel PL, Larratt LM, Mant MJ, Reiman T, Belch AR, Pilarski LM.
Only transcripts originating from the WHSC1/MMSET/NSD2 gene are uniformly dysregulated in MM patients with the t(4;14) translocation. The transcripts detected were:
- Multiple myeloma SET domain containing protein (MMSET I)
- MMSET II
- Exon 4a/MMSET III
- Response element II binding protein (RE-IIBP)
These are produced by alternative transcription initiation events and alternative splicing.
The Exon 4a/MMSET III splice variant contains a protein domain that prevents nucleolar localization.
RE-IIBP is universally dysregulated and also potentially functional in all t(4;14) patients, regardless of FGFR3 expression or breakpoint type.

van Rhee F, Szmania SM, Zhan F, Gupta SK, Pomtree M, Lin P, Batchu RB, Moreno A, Spagnoli G, Shaughnessy J, Tricot G.
This study shows that NY-ESO-1 is frequently expressed in MM with cytogenetic abnormalities, and it is capable of eliciting spontaneous humoral and T-cell immunity. MM patients with cytogenetic abnormality have increased expression of NY-ESO-1 compared to patients with normal cytogenetics (60% vs 31%). NY-ESO-1 is highly expressed in patients with relapsing disease (61%), especially when they have cytogenetic abnormalities (100%). Spontaneous NY-ESO-1-specific antibodies were detected in 33% of patients with NY-ESO-1+ MM, but not in NY-ESO-1-negative MM. Spontaneous NY-ESO-1-specific T cells were also found, and, when expanded, they were able to kill primary MM cells.

This study describes a patient with IgD-lambda MM who had a significant bleeding tendency. Both bleeding time and APTT were prolonged. Thee purified protein responsible for the aPTT prolongation was found to be a homodimer of the lambda light chain. The lambda dimer protein bound to the region of the A1 domain of vWF and interfered with the vWF-GPIb-alpha interaction.

Pilot study of 13cis-retinoic
acid+dexamethasone+alpha interferon as maintenance therapy following high-dose

Bone Marrow Transplant. 2005 May;35(10):979-84.
Friedman J, Khoury H, Adkins D, Devine S, Nervi B, Edwards T, Dipersio J, Vij R.
33 patients with multiple myeloma treated with autologous stem cell transplantation were given maintenance therapy with 13-cis-retinoic acid, dexamethasone, and interferon alpha. After a median follow-up of 35 months, only 34% of patients were in remission, and 33% died. The median progression-free survival from diagnosis was 35 months.

32 patients with newly diagnosed myeloma were treated with bortezomib for a maximum of 6 cycles. Dexamethasone was added if less than PR was achieved after 2 cycles or less than CR was achieved after 4 cycles. Response rate was 88%, CR 6%, and near-CR (IFE positive) 19%. The most common significant (grade 2 or higher) adverse events were:
- Peripheral neuropathy (31%), reversible in 50% of cases within a median of 3 months
- Myalgia (28%)
- Constipation (28%)
- Fatigue (25%)

The bisphosphonate zoledronic acid inhibits the development
of plasmacytoma induced in BALB/c mice by intraperitoneal injection of pristane.
Eur J Haematol. 2005 Jun;74(6):496-500.
Avcu F, Ural AU, Yilmaz MI, Ozcan A, Ide T, Kurt B, Yalcin A.
This study investigated the effect of zoledronic acid on the development of pristane-induced plasmacytoma in BALB/c mice. Authors found a a significant difference in survival between the group of mice treated with pristane alone and the group receiving pristane + xoledronic acid. The increased survival indicates a direct anti-tumor effect of zoledronic acid in the development of pristane-induced plasmacytomas in BALB/c mice. This hypothesis should now be further investigated in clinical trials.
Plasmablastic lymphomas and plasmablastic
plasma cell myelomas have nearly identical immunophenotypic profiles.

According to the WHO classification of lymphomas, plasmablastic lymphoma is a variant of diffuse large B-cell lymphoma (DLBCL). These authors performed IHC on 9 cases of plasmablastic lymphoma and 7 cases of plasmablastic myeloma, and they found that all cases of plasmablastic NHL and plasmablastic myeloma were negative for CD20, and positive for CD38, CD138, and MUM1/IRF4. i.e., they had a profile seen in myeloma plasma cells but not in DLBCL cells. Therefore, these results did not support the notion that plasmablastic lymphoma is a variant of DLBCL. After testing for several antigens, the authors found that the only significant difference between plasmablastic NHL and plasmablastic myeloma was the presence of EBV RNA, which was negative in all cases of plasmablastic myeloma, and positive in all cases of plasmablastic NHL.

In this study, 669 patients with relapsed myeloma were randomized to bortezomib (1.3 mg/m2 IV on days 1, 8, 15, 22 every 5 weeks for 3 cycles) vs high-dose dexamethasone (40 mg PO on days 1-4, 9-12, 17-20 every 5 weeks for 4 cycles, then on days 1-4 every 4 weeks for 5 cycles). Patients assigned to the dexamethasone arm were allowed to cross over to the bortezomib arm in case of disease progression. Patients had received 1-3 previous therapies. Results:
- Response rate was higher in the bortezomib arm (38% vs 18%)
- Rate of CR was 6% in the bortezomib arm and <1% in the dexamethasone arm
- Time to progression was longer in the bortezomib arm (6.2 months vs 3.5 months)
- Overall survival was longer in the bortezomib arm. 1-year OS was 80% in the bortezomib arm and 66% in the dexamethasone arm.
- Grade 3-4 toxicities were seen in 75% of patients in the bortezomib arm vs 60% of patients in the dexamethasone arm.

In this study, 33 patients with MM received G3139, a Bcl-2 antisense oligonucleotide targeting the Bcl-2 mRNA. G3139 was administered as continuous IV infusion for 7 days. Thalidomide and dexamethasone were added on day 4, with 21-day cycles. RR: 55%. There were 6 minimal responses, 12 PR, 4 near CR (positive immunofixation), and 2 CR. The median duration of response was 13 months. PFS: 12 months. OS: 17.4 months.

This study analyzed outcomes of 383 patients with newly diagnosed myeloma who underwent autologous stem cell transplant. The authors found that survival was predicted by response to induction therapy and also by the response after transplant.
- Median overall survival was 7.5 years in patients who had early response (PR and CR) after induction therapy, and 4.9 years in non-responders (p= 0.035)
- Attainment of CR at 3 months after SCT was prognostically important: median PFS was 7.4 years in CR group and 5.3 years in non-CR group (p= 0.023)
This data suggests that complete remission should be the goal of myeloma therapy at every stage of treatment, both pre-SCT and post-SCT.
Results of autologous and
allogeneic hematopoietic cell transplant therapy for multiple myeloma.
Bone Marrow Transplant. 2005 Jun;35(12):1133-40.
Arora M, McGlave PB, Burns LJ, Miller JS, Barke JN, Defor TE, Weisdorf DJ.
This study compared outcomes of autologous (70 patients) and myeloablative allogeneic stem cell transplant (17 patients) in multiple myeloma. Results:
- Transplant-related mortality was lower with autologous transplant (4% vs 18%)
- Complete responses were higher with allogeneic transplant (64% vs 34%)
- After autologous transplant, survival at 1 year was 86%, but it fell to 50% at 4 years, mainly because of disease relapse
- After allogeneic transplant, survival at 1 year was 64%, and it remained the same at 4 years
Therefore, although autologous transplant was associated with a lower mortality and superior short-term outcomes, allogeneic transplant produced superior long-term responses.

- Progression-free survival at 3 years: 21%
- Overall survival at 3 years: 41%
- No significant benefit was observed in heavily pretreated patients and patients with progressive disease
