and monoclonal gammopathy of undetermined significance among white and black
male United States veterans with prior autoimmune, infectious, inflammatory, and
Blood. 2008 Apr 1;111(7):3388-94.
Brown LM, Gridley G, Check D, Landgren O.
This is a retrospective study of more than 4 million male US veterans, exploring the role of prior autoimmune, infectious, inflammatory, and allergic disorders in the etiology of MM and MGUS. The analysis included 4641 patients with MM, and 2046 patients with MGUS. Significantly elevated risks of MM were associated with autoimmune (RR, 1.15), infectious (RR, 1.29), and inflammatory disorders (RR, 1.18).
- Specific prior autoimmune diseases: polymyositis/dermatomyositis, systemic sclerosis, autoimmune hemolytic anemia, pernicious anemia, and ankylosing spondylitis.
- Specific prior infectious diseases: pneumonia, hepatitis, meningitis, septicemia, herpes zoster, and poliomyelitis.
- Specific prior inflammatory diseases: glomerulonephritis, nephrotic syndrome, and osteoarthritis.
Risks for MGUS were of similar magnitude. Authors conclude that various types of immune-mediated conditions might act as triggers for MM/MGUS development.

This is a case series of 14 patients with CSF-positive MM. Patients received intra-CSF chemotherapy + RT (to the brain in 5 patients and to the spine in 6 patients). There were 6 partial responses and 8 cases of progressive disease. The median duration of response was short, only 2.5 months (range: 0-6 months). 6 patients died because of progressive neurologic disease. 6-month neurologic disease progression-free survival rate was only 7%.
Bortezomib plus melphalan and prednisone
in elderly untreated patients with multiple myeloma: updated time-to-events
results and prognostic factors for time to progression.

Mateos MV, Hernández JM, Hernández MT, Gutiérrez NC, Palomera L, Fuertes M, Garcia-Sanchez P, Lahuerta JJ, de la Rubia J, Terol MJ, Sureda A, Bargay J, Ribas P, Alegre A, de Arriba F, Oriol A, Carrera D, García-Laraña J, García-Sanz R, Bladé J, Prósper F, Mateo G, Esseltine DL, van de Velde H, San Miguel JF.
This is an updated analysis of a previously reported trial of VMP (bortezomib, melphalan, and prednisone) in elderly patients with newly diagnosed myeloma. After a median follow-up of 26 months:
- Median time to progression: 27 months with VMP vs 20 months with MP
- Median overall survival: not reached with VMP vs 26 months with MP
- 3-year survival: 85% with VMP vs 38% with MP
Since time to progression was not significantly influenced by cytogenetic abnormalities, the authors believed that VMP could overcome the adverse prognostic impact of high-risk cytogenetic abnormalities.
Suppression of abnormal karyotype predicts superior
survival in multiple myeloma.

Arzoumanian V, Hoering A, Sawyer J, van Rhee F, Bailey C, Gurley J, Shaughnessy JD Jr, Anaissie E, Crowley J, Barlogie B.
Cytogenetic studies were reviewed in 2041 patients with multiple myeloma. Cytogenetic abnormalities were found in one-third of patients at baseline, in 14% after induction therapy, 10% after stem cell transplantation, and 28% at relapse. The presence of cytogenetic abnormalities, either at baseline or at relapse, was associated with poor prognosis, whereas their disappearance after the induction therapy had a favorable impact on prognosis.

Among 804 myeloma patients undergoing stem cell transplantation, 151 had a preexisting plasma cell disorder, such as MGUS, smoldering myeloma, or a solitary plasmacytoma. The two groups of patients had similar response rates to stem cell transplant. Patients with a prior diagnosis of MGUS had a longer time to progression (27.5 vs 17.2 months, p= 0.01), and longer overall survival from transplant (80.2 vs 48.3 months, p= 0.03), whereas patients with a prior diagnosis of smoldering myeloma or solitary plasmacytoma had similar time to progression and overall survival to those of patients with de novo myeloma.

Bink K, Haralambieva E, Kremer M, Ott G, Beham-Schmid C, de Leval L, Peh SC, Laeng HR, Jütting U, Hutzler P, Quintanilla-Martinez L, Fend F.
These authors performed FISH in 38 cases of primary extramedullary plasmacytoma. 14 cases (37%) contained IgH breaks. 6 patients had a t(4;14) translocation. Loss of 13q was present in 40%, and chromosomal gains in 82%. The cytogenetics in extramedullary plasmacytomas are similar to those of MM, except for the absence of t(11;14), is different.
Dkk1-induced inhibition of Wnt signaling in osteoblast
differentiation is an underlying mechanism of bone loss in multiple myeloma.
Bone. 2008 Apr;42(4):669-80.
Qiang YW, Barlogie B, Rudikoff S, Shaughnessy JD Jr.
This study showed that Dkk1 promotes osteolysis by abrogating osteoblast differentiation mediated by bone morphogenic protein 2 (BMP-2). The autocrine Wnt signaling in osteoblasts is necessary to induce BMP-2-mediated differentiation of the pre-osteoblast cells. Wnt signaling alone does not induce this differentiation.

This study reviewed clinical outcomes in 67 multiple myeloma patients treated with vertebroplasty. The authors observed a significant improvements in all of the outcome measures after the vertebroplasty:
- 82% of patients had a significant improvement in subjective rest pain
- 89% of patients had a significant improvement in subjective activity pain
- 65% of patients required fewer narcotics after vertebroplasty
- 70% of patients had improved mobility

Streetly MJ, Gyertson K, Daniel Y, Zeldis JB, Kazmi M, Schey SA.
This is a phase 1 study of pomalidomide in 20 patients with relapsed myeloma. The maximum tolerated dose (MTD) was defined as 5 mg every other day. No thrombotic events were observed. In 17 patients, pomalidomide was continued beyond the 4 weeks of the phase 1 study, for a median of 14 months. RR was 60%, with 10% CR. Median PFS was 10.5 months and OS was 33 months.

Menon SP, Rajkumar SV, Lacy M, Falco P, Palumbo A.
This is a report of 125 myeloma patients enrolled in 3 clinical trials involving treatment with lenalidomide. 10 patients (8%) developed DVT, including 4 patients who did not receive prophylaxis. DVT was observed in 6 of 104 patients who received aspirin prophylaxis (6%). No difference in the rate of DVT was observed between patients who received erythropoietin and those who did not, whereas there was a trend for higher rate of DVT in patients treated with high-dose dexamethasone compared with low-dose corticosteroids (either prednisone, or dexamethasone 40 mg/month), but the difference was not statistically significant.
Eight-year median survival in multiple myeloma after total
therapy 2: roles of thalidomide and consolidation chemotherapy in the context of
total therapy 1.
Br J Haematol. 2008 May;141(4):433-44.
Zangari M, van Rhee F, Anaissie E, Pineda-Roman M, Haessler J, Crowley J, Barlogie B.
This study reports the rusults of Total Therapy 2, with longer follow-up. Results were better than those achieved with Total Therapy 1, in terms of CR duration, EFS, and OS. Event-free survival was 4.8 years and overall survival was 8.0 years. In patients without cytogenetic abnormalities, improved results were mainly related to post-transplant consolidation therapy, whereas in patients with cytogenetic abnormalities, improved results were mainly related to the use of thalidomide. With longer follow-up, Total Therapy 2 revealed an apparent separation of the survival curves between the two randomized groups (thalidomide vs non-thalidomide), and it did not confirm the previously observed shorter post-relapse survival of the thalidomide group.

Conner TM, Doan QD, Walters IB, LeBlanc AL, Beveridge RA.
This is a retrospective review of data from patients with multiple myeloma treated with bortezomib and subsequently retreated with the same agent, with therapy given at least 2 months apart. Median time between bortezomib treatments was 10 months. Response among 82 evaluable patients:
- Less than PR: 63%
- PR: 15%
- VGPR: 6%
- Progressive disease: 6%
- Death: 10%

El-Cheikh J, Stoppa AM, Bouabdallah R, de Lavallade H, Coso D, de Collela JM, Auran-Schleinitz T, Gastaut JA, Blaise D, Mohty M.
Among 100 myeloma patients treated with bortezomib for a median of 8 months (range: 0.1-32 months), 38% developed bortezomib-induced peripheral neuropathy. This was grade 3 in 5 patients and grade 4 in 1 patient. Median time to onset of neuropathy was 53 days (range: 11-182 days). Neuropathy improved or completely resolved in 53% of cases, at a median of 3 months (range: 1-8 months). The incidence of bortezomib-induced peripheral neuropathy was significantly higher in patients who received > 4 cycles of bortezomib, and in patients previously treated with thalidomide.

Ege H, Gertz MA, Markovic SN, Lacy MQ, Dispenzieri A, Hayman SR, Kumar SK, Porrata LF.
A retrospective analysis of the absolute lymphocyte count (ALC) was conducted in 537 patients with newly diagnosed multiple myeloma. ALC proved to be an important prognostic factor, even after multivariate analysis. After a median follow-up of 35.1 months, patients with ALC >1,400 had a superior overall survival compared with patients with ALC <1,400 (65 vs 26 months, p <0.01). The results suggested that the immune status plays an important role in the survival of MM.

This study evaluated the HLA-DRB1 phenotypic frequencies in 53 patients with smoldering/indolent myeloma and 128 patients with symptomatic myeloma. Frequency of DRB1*01 was higher in patients with smoldering myeloma than in those with symptomatic myeloma (38% vs 14%, p= 0.001) or healthy individuals (38% vs 22%, p= 0.01). The authors proposed that HLA-DRB1*01 confers a better ability to present myeloma-related antigens to immunocompetent cells, favoring a better immune response against the myeloma.

This study compared serum levels of DKK-1 in 184 untreated MM patients to those of 33 MGUS patients. Serum DKK-1 was elevated in MM as compared with MGUS (mean 11,963 pg/mL vs. 1,993 pg/mL. Serum DKK-1 levels correlated with the Durie and Salmon stage. MM patients without lytic lesions in x-rays had significantly lower DKK-1 levels than patients with lytic bone lesions. Serum DKK-1 correlated with the number of bone lesions.

This prospective study in 685 patients with newly diagnosed multiple myeloma evaluated the prognostic impact of several antigenic markers, assessed by flow cytometry. Worse prognosis, with shorter PFS and OS, was seen with expression of both CD19 and CD28 and absence of CD117. CD28 expression was associated with t(14;16) and del(17p), and the absence of CD117 was associated with t(4;14) and del(13q). Patients could be stratified into 3 risk categories:
- Good risk: CD28 negative, CD117+
- Intermediate risk: either both markers negative or both positive
- Poor risk: CD28+, CD117 negative
Progression-free survival was 45, 37, and 30 months, respectively.
Instability of immunophenotype in plasma cell
Am J Clin Pathol. 2008 Jun;129(6):926-33.
Cao W, Goolsby CL, Nelson BP, Singhal S, Mehta J, Peterson LC.
In this study of flow cytometry in 56 myeloma patients, 23 patients (41%) showed a change in immunophenotype (CD52 in 17 cases, CD20 in 7 cases, and CD56 in 6 cases). The instability of the immunophenotype in multiple myeloma can have important implications, especially in the detection of residual disease, and when considering the potential application of antigen-directed therapy.

Kumar SK, Dingli D, Dispenzieri A, Lacy MQ, Hayman SR, Buadi FK, Rajkumar SV, Litzow MR, Gertz MA.
This study assesses the effect of initial therapy on the outcome of 472 patients with multiple myeloma undergoing autologous SCT within 12 months of diagnosis. The induction therapy consisted of: VAD, Dexamethasone, Dexamethasone + Thalidomide, and Dexamethasone + Lenalidomide. There was no difference in the response rates to the autologous SCT. The median time to progression after the SCT was 21-27 months and median overall survival was 62-70 months. The authors conclude that in patients undergoing early autologous SCT, the type of induction therapy has no long-term impact on the outcome of the transplant.

Chang JE, Juckett MB, Callander NS, Kahl BS, Gangnon RE, Mitchell TL, Longo WL.
31 patients with myeloma were treated with autologous stem cell transplant and then thalidomide 50 mg PO qhs, escalated to a maximum dose of 200 mg per day.
- Treatment was poorly tolerated, mainly because of peripheral neuropathy.
- Maintenance at the dose of 200 mg was not feasible (goal achieved in 55% of patients). The median tolerated dose was 100 mg.
- No DVT was observed.
- CR + VGPR: 65% at 1 year and 42% at 2 years.
- Median OS: > 60 months. Median PFS: 20.8 months.

Ciolli S, Leoni F, Casini C, Breschi C, Santini V, Bosi A.
This study compared VTD (28 patients) with VTD + Doxil (42 patients) in advanced MM.
- Velcade 1.0 mg/m2 IV on days 1, 4, 8, 11 in a 28-d cycle
- Thalidomide 100 mg PO qhs
- Dexamethasone 24 mg PO on the day of, and the day after Velcade
- Doxil 50 mg/m2 (30 mg/m2 for patients older than 75 years) IV on day 4, 1 hour after bortezomib infusion
VTD + Doxil produced better results, in terms of overall response rate (81% vs 50%), time to progression (19 vs 11 months), and progression-free survival (15 vs 8 months).

In this study, 64 patients with relapsed/refractory myeloma were treated with PAD for a median of four cycles.
- Bortezomib 1.3 mg/m2 IV days 1, 4, 8, 11
- Doxorubicin 20 mg/m2 IV days 1, 4 or pegylated liposomal doxorubicin 30 mg/m2 IV day 1
- Dexamethasone 40 mg PO days 1-4
Cycles were repeated every 28 days. 43 patients (67%) achieved at least a PR, including 16 (25%) with at least a VGPR. At 1 year, EFS was 34% and OS 66%. Grade 3-4 toxic effects included thrombocytopenia (48%), neutropenia (36%), infections (15%), anemia (13%), gastrointestinal disturbances (11%), peripheral neuropathy (10%), and CHF (2 patients).

These authors observed low stem cell yield after lenalidomide induction therapy. With G-CSF 10 mcg/Kg for 4 days, 12 of 28 patients (43%) failed to collect a sufficient number of CD34+ cells/Kg for even one transplant. 3 patients also failed collection after plerixafor. The authors conclude that patients with prior exposure to lenalidomide should undergo mobilization chemotherapy with cyclophosphamide.
