From January 1988 until December 1990, 99 previously untreated patients with multiple myeloma (MM) were enrolled in a randomized prospective study comparing two combination chemotherapies with and without MCNU as induction therapy for MM; 49 patients with vindesine, melphalan and prednisolone (VMP therapy) versus 50 patients with MCNU, vindesine, melphalan and prednisolone (MCNU-VMP therapy). Seventy-two evaluable patients (34 patients in the VMP group, 38 in the MCNU-VMP group) were analyzed. The response rate was slightly higher with MCNU-VMP than with VMP (81.6% vs. 64.7%). In 43 responders (21 patients in the VMP group and 22 in the MCNU-VMP group) who were treated with the same regimen as the induction therapy to maintain remission, the remission duration was significantly longer in patients treated with MCNU-VMP than in those treated with VMP (median > 10.1 vs. 8.0 months, P = 0.018), particularly in patients with PS 3-4. The remission duration in the MCNU-VMP group was also slightly longer in the patients with stage III disease and who were older than 65 years. The median survival time showed no significant difference between the VMP group (20.3 months) and the MCNU-VMP group (> 15 months). Leukopenia, thrombocytopenia and nausea/vomiting were found to be somewhat severe in the MCNU-VMP group. In summary, MCNU-VMP therapy is effective as induction therapy for MM.

The object of this study was to determine the efficacy and safety of glycosylated recombinant human granulocyte colony-stimulating factor (rHuG-CSF; lenograstim) after combination chemotherapy consisting of ranimustine, vindesine, melphalan and prednisolone (MCNU-VMP). One hundred thirty-nine consecutive patients with newly diagnosed multiple myeloma (MM) were allocated at random to a lenograstim group (n = 70) or a placebo group (n = 69). Patients were treated with two cycles of MCNU-VMP, and either lenograstim (2 microg/kg daily, s.c.) or placebo was administered from the day neutrophils decreased to less than 1.000/microl and was discontinued when neutrophils exceeded 5,000/microl. The median duration of neutropenia (neutrophils under 1,000/microl) was significantly shorter for the lenograstim group than the placebo group (2 days vs 9 days in the first cycle; 1 day vs 13 days in the second cycle). The incidence of febrile neutropenia in the first cycle was significantly lower in the lenograstim group than in the placebo group (9.2% vs 30.4%). No life-threatening infections were observed in either group. The two cycles of MCNU-VMP therapy were completed in 90.8% of the patients, and a higher average relative dose intensity (ARDI; 0.94) was achieved in the lenograstim group. The tumor response rate of the lenograstim group (57.8%) was higher than that of the placebo group (43.1%), but the difference was not statistically significant (chi2 = 2.634, df = 1, P = 0.105). Lenograstim was well tolerated, and no unexpected adverse events occurred. Lenograstim proved effective in controlling chemotherapy-induced neutropenia in MM patients under MCNU-VMP therapy.

A 75-year-old woman was referred to us because of cough, high fever and skin erythema in April 1999. Malignant lymphoma (diffuse mixed cell type) was previously diagnosed in 1990 and she achieved complete remission after treatment with a series of CHOP regimen treatments. In 1998, multiple myeloma (IgG lambda type) was diagnosed and she was treated with a combination of melphalan and prednisolone. On physical examination, superficial lymphadenopathy and skin erythema were noted. Biclonal gammopathy (IgG kappa/lambda) was shown in serum, and Bence Jones protein in urine. Computed tomography showed pleural effusion and swelling of paraaortic lymph nodes. The bone marrow examination showed an increased number of abnormal plasma cells (19.2%) and no evidence of lymphoma. Left axillary lymph node biopsy revealed that she had non-Hodgkin's lymphoma (immunoblastic lymphadenopathy-like T cell lymphoma). She was treated with the CHOP regimen at reduced doses for both diseases. The lymphoadenopathy reduced after 6 courses of CHOP and 4 courses of CHOPE (CHOP + VP16), however, she had bone pain on November 1999 and received treatment with MCNU-VMP (MCNU + VDS + L-PAM + PSL). Her rib pain improved, but she died of systemic infection of herpes zoster virus. We report here a rare case of malignant lymphoma concomitant with multiple myeloma.

Standard first-line treatment for elderly multiple myeloma (MM) patients ineligible for stem cell transplantation is melphalan plus prednisone (MP). However, complete responses (CRs) are rare. Bortezomib is active in patients with relapsed MM, including elderly patients. This phase 1/2 trial in 60 untreated MM patients aged at least 65 years (half older than 75 years) was designed to determine dosing, safety, and efficacy of bortezomib plus MP (VMP). VMP response rate was 89%, including 32% immunofixation-negative CRs, of whom half of the IF- CR patients analyzed achieved immunophenotypic remission (no detectable plasma cells at 10(-4) to 10(-5) sensitivity). VMP appeared to overcome the poor prognosis conferred by retinoblastoma gene deletion and IgH translocations. Results compare favorably with our historical control data for MP--notably, response rate (89% versus 42%), event-free survival at 16 months (83% versus 51%), and survival at 16 months (90% versus 62%). Side effects were predictable and manageable; principal toxicities were hematologic, gastrointestinal, and peripheral neuropathy and were more evident during early cycles and in patients aged 75 years or more. In conclusion, in elderly patients ineligible for transplantation, the combination of bortezomib plus MP appears significantly superior to MP, producing very high CR rates, including immunophenotypic CRs, even in patients with poor prognostic features.

A 68-year-old woman suffering from a left iliac tumor and severe back pain was admitted to another hospital in May 1999. The bone X-ray, CT scan and MRI demonstrated a 7 cm x 5 cm left iliac tumor with osteolysis and she was transferred to our hospital. Angiography demonstrated multiple hypervascular lesions in the left ilium, lumbar vertebrae, left ischium, left pubis and left rib. The tumor was resected and diagnosed as a plasmacytoma. Immunoelectrophoresis did not show any M-protein in the serum and urine, but the patient was diagnosed as having a non-secretory or low producing multiple myeloma because of the presence of 42.8% of abnormal plasma cells in the bone marrow aspirate. Her symptoms improved following 3 courses of MCNU-VMP therapy and the bone marrow plasma cells decreased to less than 5%. She was discharged and treated as an outpatient but relapsed and died of chemotherapy-resistant myeloma. We report this case because macro-angiogenesis in a multiple myeloma demonstrated by angiography is rare and interesting.

The purpose of this study was to evaluate the efficacy and safety of short-course bortezomib, melphalan, prednisone (VMP) in previously untreated multiple myeloma as frontline therapy for transplant-ineligible patients and induction prior to autologous stem cell transplantation (ASCT). Patients received up to 6 28-day cycles of bortezomib 1.3 mg/m(2), days 1, 4, 8, and 11, plus melphalan 6 mg/m(2) and prednisone 60 mg/m(2), days 1-7. After 2-6 cycles, eligible and consenting patients could proceed to ASCT. Responses were assessed by International Uniform Response Criteria. The primary endpoint was complete response (CR) rate with VMP. Forty-five patients were enrolled. Among 44 evaluable patients, response rate was 95%, including 18% >or=CR (9% stringent CR), 27% very good partial responses (VGPR), and 50% partial responses (PR). Twenty patients proceeded to ASCT. Stem cell collection was successful in all; median yield was 5.6 x 10(6) CD34(+) cells/kg. Posttransplant response rates were 30% >or=CR (10% stringent CR), 65% VGPR, and 5% PR. After median follow-up of 14.0/14.6 months, median time to progression and progression-free survival were both 19.8/27.9 months in non-ASCT/ASCT patients. Seven patients have died; 1-year survival rates were 82%/95% in non-ASCT/ASCT patients. The most common grade 3/4 toxicities were thrombocytopenia (20%), neutropenia (28%), and infection (9%). Peripheral neuropathy grade 2-4 was the most common nonhematopoietic side effect occurring 17 patients (38%), although it was typically reversible, and only 5 patients (11%) discontinued therapy as a result of it. Short-course VMP is highly effective and generally well tolerated, both as initial treatment in non-ASCT patients and induction prior to ASCT. VMP did not negatively affect stem cell collection. Longer follow-up and prospective phase III trials are required to validate these initial observations.

PURPOSE To assess bortezomib plus melphalan and prednisone (VMP) and melphalan and prednisone (MP) in previously untreated patients with multiple myeloma (MM) with renal impairment enrolled on the phase III VISTA study, and to evaluate renal impairment reversibility. PATIENTS AND METHODS Patients received nine 6-week cycles of VMP (bortezomib 1.3 mg/m(2), melphalan 9 mg/m(2), prednisone 60 mg/m(2)) or MP. Patients with serum creatinine higher than 2 mg/dL were excluded. Results In the VMP/MP arms, 6%/4%, 27%/30%, and 67%/66% of patients had baseline glomerular filtration rate (GFR) of < or = 30, 31 to 50, and higher than 50 mL/min, respectively. Response rates were higher and time to progression (TTP) and overall survival (OS) longer with VMP versus MP across renal cohorts. Response rates with VMP and TTP in both arms did not appear significantly different between patients with GFR < or = 50 or higher than 50 mL/min; OS appeared somewhat longer in patients with normal renal function in both arms. Renal impairment reversal (baseline GFR < 50 improving to > 60 mL/min) was seen in 49 (44%) of 111 patients receiving VMP versus 40 (34%) of 116 patients receiving MP. By multivariate analysis, younger age (< 75 years; P = .006) and less severe impairment (GFR > or = 30 mL/min; P = .027) were associated with higher reversal rates. In addition, treatment with VMP approached significance (P = .07). In both arms, rates of grade 4 and 5 adverse events (AEs) and serious AEs appeared higher in patients with renal impairment; with VMP, rates of discontinuations/bortezomib dose reductions due to AEs did not appear affected. CONCLUSION VMP is a feasible, active, and well-tolerated treatment option for previously untreated patients with MM with moderate renal impairment, resulting in 44% renal impairment reversal.

No survival advantage of autologous stem cell transplantation (ASCT) has been documented for patients older than 65 years, and in the era of thalidomide (Thalomid), bortezomib (Velcade), and lenalidomide (Revlimid), ASCT has a diminished role in the front-line treatment of older patients with myeloma. For these individuals and for those who cannot or choose not to undergo ASCT, the initial treatment regimens now recommended by both the National Comprehensive Cancer Network and the International Myeloma Working Group are melphalan (Alkeran)/prednisone/thalidomide (MPT), bortezomib/melphalan/prednisone (VMP), and lenalidomide/low-dose dexamethasone. Melphalan/prednisone should no longer be considered the reference treatment, although it may be appropriate for a small number of patients with serious comorbidity and/or poor performance status. Advantages of VMP over MPT include rapid response, high rates of complete response, patient compliance, and more extensive evidence of efficacy in patients with certain cytogenetic abnormalities. Lenalidomide/low-dose dexamethasone is particularly appropriate for patients with preexisting neurotoxicity and those who wish to postpone ASCT. Toxicity profiles differ among the newly established and emerging regimens, and oncology teams must take care to apply the appropriate risk management measures, including dose reduction where necessary.

The phase 3 Velcade as Initial Standard Therapy in Multiple Myeloma: Assessment with Melphalan and Prednisone study in newly diagnosed multiple myeloma patients ineligible for high-dose therapy demonstrated that bortezomib-melphalan-prednisone (VMP) was superior to melphalan-prednisone across all efficacy end points. We assessed the prognostic impact of response on time-to-event parameters in the intent-to-treat population. Patients received nine 6-week cycles of treatment. Time to progression, time to next therapy, and treatment-free interval were associated with quality of response. When European Group for Blood and Marrow Transplantation criteria were used, complete response (CR) was associated with significantly longer time to progression (hazard ratio [HR] = 0.45, P = .004), time to next therapy (HR = 0.46, P = .0004), and treatment-free interval (HR = 0.38, P < .0001) versus partial response, but there was no significant difference in overall survival (HR = 0.87, P = .54); similar differences were seen with CR versus very good partial response by uniform criteria. Quality of response improved with prolonged VMP treatment, with 28% of CRs achieved during cycles 5-9. CR duration appeared similar among patients with "early" (cycles 1-4) and "late" CRs (cycles 5-9) and among patients receiving 9 versus < 9 cycles of bortezomib within VMP. These results highlight that CR is an important treatment goal and support prolonged VMP therapy to achieve maximal response. This study is registered at http://www.clinicaltrials.gov as NCT00111319.

For many years, the oral combination melphalan-prednisone (MP) has been considered the standard of care for patients with multiple myeloma (MM) not eligible for autologous stem cell transplantation. In the era of novel agents, the introduction of immunomodulatory drugs and proteasome inhibitors has challenged the role of MP and led to new standards of care for this disease. Five randomized phase III studies compared the traditional MP with the MP plus thalidomide (MPT). All these studies showed a prolonged time to progression (TTP) with the 3-drug combination. However, in only two of these trials this advantage translated into an improvement in overall survival (OS). In another randomized trial, MP plus bortezomib (VMP) was correlated with an increase in both TTP and OS compared with MP. Preliminary data showed the superiority of the association of VMP plus thalidomide followed by bortezomib-thalidomide maintenance (VMPT-VT) vs VMP and melphalan-prednisone-lenalidomide followed by lenalidomide maintenance (MPR-R) compared to MP. Promising results have also been reported with the combination of lenalidomide plus low-dose dexamethasone. The availability of different efficacious regimens provided clinicians with the opportunity of tailoring the proper and specific approach for each patient. The choice should be based on patients' comorbidities and biologic age, while taking into account the expected toxicity profiles of each treatment regimen. Moreover, an accurate management of therapy-related adverse events and a gentler approach, particularly for patients older than 75 years, with appropriate age-adjusted dose reductions, should be considered to further improve outcome.
