These authors used gene expression profiles of plasma cells from 182 MM patients obtained at diagnosis to identify prognostic markers. The validity of our model was assessed in in three independent cohorts of 853 MM patients. High-risk patients had overexpression of genes involved in cell cycle progression and its surveillance, whereas low-risk patients had hyperdiploid signatures.

Serum levels of free light chains were obtained at the time of diagnosis in 790 patients with multiple myeloma. The levels had prognostic significance, with inferior survival in 479 patients with a kappa/lambda ratio >32 (kappa myeloma) or <0.03 (lambda myeloma) compared with 311 patients with a kappa/lambda ratio between 0.03 and 32 ( 30 vs 39 months). The authors incorporated the abnormal kappa/lambda ratio with the ISS, for improved risk stratification.
Oral melphalan, prednisone, and
thalidomide in elderly patients with multiple myeloma: updated results of a
randomized controlled trial.

This is an updated analysis of efficacy and safety of MP vs MPT in multiple myeloma, after a median follow-up of 38.1 months.
- The median PFS was 14.5 months with MP and 21.8 months with MPT (p= 0.004)
- The median OS was 47.6 months with MP and 45.0 months with MPT (p= 0.79)
The results confirmed the activity of MPT for PFS but they failed to show a survival advantage. This is presumably due to the fact that salvage therapy with thalidomide or bortezomib improved survival after progression in the MP group, but not in the MPT group.

Chanan-Khan A, Sonneveld P, Schuster MW, Stadtmauer EA, Facon T, Harousseau JL, Ben-Yehuda D, Lonial S, Goldschmidt H, Reece D, Neuwirth R, Anderson KC, Richardson PG.
The authors evaluated the incidence of VZV reactivation in 663 patients with relapsed myeloma enrolled in the APEX trial (phase III trial comparing bortezomib vs dexamethasone). They found that bortezomib treatment was associated with a significantly higher incidence of VZV reactivation compared with dexamethasone treatment (13% vs 5%, p =0.0002). Time to onset of VZV reactivation and absolute lymphocyte counts at baseline were similar between the two arms. The incidence of other (non-VZV) herpes viral infections was similar between the two arms. The authors concluded that the use of antiviral prophylaxis considered in all patients treated with bortezomib.

Reece DE, Rodriguez GP, Chen C, Trudel S, Kukreti V, Mikhael J, Pantoja M, Xu W, Stewart AK.
This is a phase I-II trial that evaluated the combination of bortezomib, cyclophosphamide, and prednisone in 37 patients with relapsed/refractory MM. Regimen:
- Bortezomib 1.3-1.5 mg/m2 IV on days 1, 4, 8, 11
- Cyclophosphamide 300 mg/m2 PO once a week
- Prednisone PO on alternate days
- Response rate was 95%, when including minor responses. CR was reached in >50% of patients.
- 1-year progression-free survival: 83%
- 1-year overall survival 100%
Poor outcomes for IgD
multiple myeloma patients following high-dose melphalan and autologous stem cell
transplantation: a single center experience.
J Korean Med Sci. 2008 Oct;23(5):819-24.
Chong YP, Kim S, Ko OB, Koo JE, Lee D, Park SH, Park SJ, Lee D, Kim SW, Suh C.
This is a small study comparing outcomes of 8 patients with IgD myeloma vs 69 patients with other types of myeloma. Outcomes after autologous stem cell transplant were inferior among patients with IgD MM:
- The median event-free survival was 6.9 months in IgD MM vs 11.5 months in other types of MM
- The median overall survival was 12 months vs 55.5 months in other types of MM

163 patients with asymptomatic myeloma were randomized to receive either zoledronic acid 4 mg IV monthly x12 (81 patients) or observation (82 patients). Progression to symptomatic myeloma was similar in the two groups: 44.4% of patients in the zoledronic acid group and 45.1% of the patients in the control group. The median time to progression was also similar (67 vs 59 months, p= 0.8312). At progression, the skeletal complications were reduced in the zoledronic acid group (55.5% vs 78.3%, p= 0.041)ONJ was seen in 1 patient. This study demonstrated that zoledronic acid reduced the development of skeletal complications, but it did not reduce/delay the progression of the disease. The results do not support the notion that bisphosphonate may have a direct antineoplastic activity.

This is a prospective study which evaluates the prognostic significance of flow cytometry in detecting minimal residual disease after stem cell transplant. 295 patients with newly diagnosed myeloma underwent autologous stem cell transplant, and disease remission was evaluated at day 100 after transplant. In the group of patients with minimal residual disease by flow cytometry, the median progression-free survival was 37 months, whereas in the group of patients with negative flow cytometry (two-thirds of patients), the median PFS was 71 months. Overall survival was also different between the two groups (89 months vs not reached. The authors demonstrated a prognostic significance even when they defined CR by immunofixation status, but at multivariate analysis the presence of minimal residual disease detected by flow cytometry was the most important independent prognostic factor.

Among 700 patients with monoclonal immunoglobulins, 10 (1.4%) were found to be HCV+. The monoclonal component was purified in 7 cases. The monoclonal Ig reacted against:
- The C22-3 fragment of the HCV-core protein (4 cases: 2 IgG, 1 IgA, and 1 IgM)
- The NS-4 of HCV (2 cases: 2 IgG)
- Did not recognize HCV (1 case)
Interestingly, 1 of 4 patients with monoclonal antibodies against the HCV-core protein developed multiple myeloma.
Antibiotic prophylaxis before dental procedures may reduce

Montefusco V, Gay F, Spina F, Miceli R, Maniezzo M, Teresa Ambrosini M, Farina L, Piva S, Palumbo A, Boccadoro M, Corradini P.
This retrospective analysis of 178 patients with MM showed that antibiotic prophylaxis before dental procedures may prevent ONJ. 75 patients received at least one dental procedure, and 43 patients received antibiotic prophylaxis. 9 patients developed ONJ. Only 1 case of ONJ was not correlated with dental procedures. Interestingly, all 8 cases of ONJ observed with dental procedures occurred in the group of patients without antibiotic prophylaxis.
Mobilization of peripheral blood

Tricot G, Barlogie B, Zangari M, van Rhee F, Hoering A, Szymonifka J, Cottler-Fox M.
After mobilization chemotherapy with DT-PACE, patients received either filgrastim bid or peg-filgrastim 6 mg SC on days +6 and +13 (the second dose was held if WBC were >100,000 by day +13). The authors considered peg-filgrastim the standard of care for stem cell mobilization because of its advantages:
- Lower median number of growth factor injections (2 vs 26)
- Higher median number of CD34+ cells/kg collected on day 1
- Higher percentage of patients who collected 15 million CD34+ cells/Kg in 3 days
- Faster neutrophil recovery after transplant

110 patients with multiple myeloma not in CR/nCR after a first autologous transplant received a second transplant, either second autologous transplant (85 patients) or a RIC allogeneic transplant (25 patients), depending on the availability of a matched sibling donor. Results:
- Transplantation-related mortality: 16% in the auto-allo group and 5% in the auto-auto group (p= 0.07)
- CR: 40% in the auto-allo group and 11% in the auto-allo group (p =0.001)
- Median PFS: not reached in the auto-allo group and 31 months in the auto-auto group (trend: p= 0.08)
- Median EFS and OS: no statistical difference
- Chronic GVHD: 66%
The auto-allo group reached an encouraging plateu of PFS, but the allogeneic transplant was associated with high morbidity and mortality, as expected.

This study analyzed 632 MM patients treated with induction chemotherapy followed by autologous stem-cell transplantation, and found that post-SCT response markedly influenced outcomes: patients who achieved CR had better median EFS (61 v 40 months) and OS (not reached) than patients who achieved nCR. Similarly, patients who achieved nCR had better median EFS (40 vs 34 months) and OS (not reached vs 61 months) than patients who achieved PR. Trends in the same direction were observed with the pre-SCT response. Therefore, improvements in response were associated with prolonged survival.
