- [Show abstract] [Hide abstract] ABSTRACT: Filgrastim and lenograstim are the standard granulocyte colony-stimulating factor (G-CSF) agents for peripheral blood stem cell mobilization (PBSC) in patients who undergo autologous stem cell transplantation. To assess whether biosimilars are effective, we conducted a single-center, prospective study that included 40 consecutive de novo multiple myeloma patients who received cyclophosphamide 4 g/m(2) per day plus biosimilar filgrastim G-CSF to mobilize PBSC. These patients were compared with a group of 37 patients matched for age, diagnosis, previous chemotherapy and mobilization who had been treated with originator G-CSF. The mean number of CD34+ cells/μL in the peripheral blood was 199.6 ± 207.4 in the biosimilar and 192.8 ± 154.7 in the originator group (P = 0.87). The median number of CD34+ cells/kg recipient collected was 11.5 ± 5.8 and 12.3 ± 5.3 in the biosimilar and originator groups, respectively (P = 0.51). The mobilization failure rate was 2.5% and 2.7% in the biosimilar filgrastim and originator filgrastim cohorts (P = NS), respectively. Twenty-nine patients in the biosimilar group and 28 patients in the originator group underwent autologous transplantation. There were no statistically significant differences between the biosimilar and originator G-CSF cohorts in terms of hematopoietic recovery parameters and transplant-related toxicities. The efficacy of biosimilar G-CSF appears to be equivalent to the reference G-CSF. Copyright © 2015 International Society for Cellular Therapy. Published by Elsevier Inc. All rights reserved.
- [Show abstract] [Hide abstract] ABSTRACT: Aim and Methods To investigate the correlation between the long term prognosis of Multiple Myeloma (MM) and the quality of response to therapy in a cohort of 173 patients treated with high-dose melphalan and autologous transplantation in the era of old drugs. Results The response distribution after transplant on the series was CR of 33 cases (19%), nCR of 38 cases (22%), VGPR of 30 cases (17%), PR of 65 cases(38%) and SD of 7 cases(4%). Patients were followed up for 48±36 months. Median overall survival (OS) was not reached for CR group . Progression Free Survival (PFS) was 122 months for CR, 55 months for nCR, 56 months for VGPR, 32 months for partial remission (PR) and 22 months for Stable Disease (SD) cases. Significant differences in PFS and OS were found between the CR and nCR groups (P=0.003 and P=0.001), between the CR and VGPR groups (P=0.002 and P=0.001) and between the CR and PR groups (P=0.000 and P=0.001). Responses were clustered in three main categories, i.e. CR, nCR + VGPR + PR and SD. The respective 10-year PFS and OS values were 58% and 70% for CR, 15% and 18% for nCR + VGPR + PR, and 0% and 0% for SD. Conclusions The achievement of depth and prolonged response represents the most important prognostic factor. The relapse rate is low for patients in CR after 10 years of follow-up, possibly signifying a cure.
- [Show abstract] [Hide abstract] ABSTRACT: This report presents the totality of evidence through a systematic review that assessed either the efficacy or safety of bortezomib-based regimens in multiple myeloma with renal impairment. A systematic and comprehensive search of the literature was performed using MEDLINE databases from 1978 to December 1, 2010, and a hand search of references. We used the following medical subject headings (MESH) to identify potential studies: 'myeloma renal failure' (1,225 hits) and 'bortezomib' (2,554 hits). An additional search performed by combining the MESH terms 'myeloma renal failure' and 'bortezomib' yielded 50 citations. Five additional case-control studies judged relevant for the purpose of study were also included. In total, 6 case reports, 9 case series and 9 case-control studies were identified that reported on myeloma, renal failure and bortezomib. In this review, only the case series and case-control studies were considered. The results of our search led to the following conclusions: (1) bortezomib is feasible and well tolerated and its efficacy and safety are not substantially modified by renal failure patients, (2) renal failure should not induce physicians to reduce doses, since the efficacy of bortezomib is attained also in dialyzed patients who may achieve dialysis independence, and (3) standard doses of bortezomib (i.e. 1.3 mg/m(2) on days 1, 4, 8, 11) associated with dexamethasone yield satisfactory tumor response, generally obtained shortly after starting therapy. Although many questions remain unanswered, our effort should be considered a relevant scientific and practical address for generating a diagnostic and therapeutic algorithm to be used in patients with renal impairment related to multiple myeloma.
- [Show abstract] [Hide abstract] ABSTRACT: We recently published a study aiming to verify the frequency of amyloid deposits in the bone marrow of patients with multiple myeloma (MM) who did not present any signs or symptoms of systemic amyloidosis, applying the Congo red technique on bone marrow smears obtained by aspiration from the posterior iliac spine. The results suggested that nearly 40% of patients affected by MM may have amyloid deposits in their bone marrow. Subsequently, this finding has not been confirmed by another study performed with histological specimens of bone marrow in a similar clinical setting. To explain this discrepancy, we performed a comparative study on the bone marrows of 36 patients affected by MM, evaluated by both cytological and histological techniques. The results of this study confirm the high frequency of amyloid deposits in the bone marrow of patients affected by MM when the analysis is made on cytological smears, and indicate that the presence of amyloid on marrow smears is confirmed by core biopsies simultaneously performed in only 25% of cases. Should further studies confirm our findings, cytological assessment could be considered a sensitive technique to detect bone marrow amyloid deposits.
- [Show abstract] [Hide abstract] ABSTRACT: Lenalidomide is a thalidomide analogue, designed to have improved efficacy and tolerability over the parent drug. The aim of this retrospective analysis is to evaluate the impact of thalidomide therapy on lenalidomide response and outcome in relapse or refractory multiple myeloma patients. A total of 106 relapsed or refractory multiple myeloma patients received lenalidomide 25mg plus dexamethasone as salvage therapy; 80 patients progressed on thalidomide treatment (thalidomide-resistant) and 26 patients discontinued thalidomide in at least partial remission (thalidomide-sensitive). Median time from diagnosis to lenalidomide treatment was 57 months. Median prior lines of therapies were 3, range 1-6. 62% of patients were previously treated with autologous stem cell transplantation, and 71% with bortezomib-based regimens. In the thalidomide-resistant and -sensitive groups, the at least partial response rates were 56.2% and 61.5% (P = .45), including at least VGPR rates of 16.2% and 11.5%; the median progression free survival was 10 and 12 months (P=.12) and the median overall survival was 17 and 18.5 months (P = .50), respectively. Lenalidomide may be equally effective in heavily pre-treated multiple myeloma patients who are thalidomide-resistant or thalidomide-sensitive to a previous therapy.

- [Show abstract] [Hide abstract] ABSTRACT: Renal impairment (RI) is a severe complication throughout the course of multiple myeloma (MM). Bortezomib has been shown to be highly active in MM patients with RI. We designed this retrospective analysis to investigate the safety and efficacy of bortezomib-based therapy in 117 MM patients with RI, 14 cases required dialysis. A total of 603 cycles of bortezomib were administered (median number, five cycles/patient). Ten patients required early discontinuation of bortezomib because of WHO grade IV toxicity. The rate of bortezomib discontinuation in cases with severe, moderate and mild RI was 11%, 5% and 0%, respectively (P = NS). Overall, 91 episodes of WHO grade III/IV toxicity were observed. At least a partial response was documented in 83/113 evaluable patients (73%), including complete response (19%) and near complete response (8%). The overall response rate was similar across RI subgroups. Reversal of RI was documented in 41% of patients after a median of 2.3 months (range 0.4–7.9). In three of 14 patients on dialysis, renal replacement therapy was discontinued after 1, 1 and 4 months. The 2-yr estimate of response duration and overall survival was 70% and 51%, respectively. In conclusion, bortezomib-based regimens are safe and effective and should be considered as appropriate treatment options for MM patients with any degree of RI.
- [Show abstract] [Hide abstract] ABSTRACT: Systemic AL amyloidosis is associated with nearly 15% of cases of multiple myeloma, but data on the frequency and significance of amyloid deposits in the bone marrow of patients affected by multiple myeloma without clinical signs of systemic amyloidosis are scanty. Bone marrow smears of 166 unselected patients affected by multiple myeloma (126 at diagnosis and 40 after treatment) were stained with Congo red and studied by transmission and birefringence microscopy. Both focal and diffuse storages were considered positive. Overall, 67 patients were positive and 99 were negative to Congo red and apple-green birefringence. In particular, 51 of the 126 patients studied at diagnosis and 16 of the 40 patients with advanced disease were positive. Seventeen patients were reassessed after a mean follow-up of 32 months (range: 6-91): disappearance of amyloid deposits was verified in three cases, all responsive to bortezomib-based regimens. The preliminary data available suggest that amyloid deposition in the marrow of myeloma patients is frequent, as it can be traced in nearly 40% of cases. We failed to find correlations between bone marrow amyloid deposits and immunoglobulin type, disease stage, plasma cells percentage, hemoglobin, calcium, creatinine, albumin, or beta(2)microglobulin. Significantly higher incidence of moderate/severe peripheral neuropathy was found in patients with marrow amyloid exposed to potentially neurotoxic antineoplastic agents. Further studies and prolonged follow-up are needed to validate our findings and to define possible prognostic aspects.
- [Show abstract] [Hide abstract] ABSTRACT: The recent development of reduced intensity conditioning and allotransplantation (RICT) has opened a new way to assure engraftment of donor cells while reducing early transplant-related mortality. We evaluated the combination of high-dose therapy and autologous peripheral blood stem cells transplantation (APBSCT) followed by RICT to extend the benefit of allografting procedures in de novo multiple myeloma (MM) patients. Fifteen subjects with stage III MM (median age 51 years, range 40-57) received high dose melphalan (200 mg/m(2)) followed by APBSCT previously collected after cyclophosphamide (4 g/m(2)) and granulocyte colony-stimulating factor (G-CSF). After 3-4 months from APBSCT, the patients underwent RICT, consisting of fludarabine 30 mg/m(2) + cyclophosphamide 300 mg/m(2) on days -4, -3, and -2. Acute graft-versus-host disease (GVHD) occurred in 2 patients; 6 patients developed chronic GVHD; 4 patients developed CMV antigenemia and were treated pre-emptively with ganciclovir. No transplant related mortality was shown. Response was simultaneously measured by both electrophoresis (EP) and immunofixation (IF); when IF was negative, patients were classified in complete remission (CR) and when it remained positive, near CR (nCR). After a median follow up of 44 months post APBSCT, 100 and 43% of patients are still alive and progression-free, respectively. Overall, the CR + nCR rate after dose-reduced allograft was enhanced from 26.7 to 73.3%. A correlation not statistically significant between GVHD and remission was found. In conclusion, an up-front tandem strategy with a very low reduced intensity-conditioning regimen for allografting following autografting is feasible and induces high CR/nCR rate in MM.
