Review
BACKGROUND
Paraproteinaemic neuropathy refers to those neuropathies associated with a monoclonal gammopathy or paraprotein. The most common of these present with a chronic, predominantly sensory, symmetrical neuropathy, similar to chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) but with relatively more sensory involvement, both clinically and neurophysiologically. The optimal treatment for neuropathies associated with IgG and IgA monoclonal gammopathy of uncertain significance is not known. This is an update of a review first published in 2007.
OBJECTIVES
To assess the effects of any treatment for IgG or IgA paraproteinaemic peripheral neuropathy.
SEARCH METHODS
On 18 January 2014 we searched the Cochrane Neuromuscular Disease Group Trials Specialized Register, CENTRAL, MEDLINE and EMBASE. We also checked bibliographies for controlled trials of treatments for IgG or IgA paraproteinaemic peripheral neuropathy. We checked clinical trials registries for ongoing studies in November 2014.
SELECTION CRITERIA
We considered for inclusion randomised controlled trials (RCTs) and quasi-RCTs using any treatment for IgG or IgA paraproteinaemic peripheral neuropathy. We excluded people with IgM paraproteins. We excluded people where the monoclonal gammopathy was considered secondary to an underlying disorder. We included participants of any age with a diagnosis of monoclonal gammopathy of uncertain significance with a paraprotein of the IgG or IgA class and a neuropathy. Included participants were not required to fulfil specific electrophysiological diagnostic criteria.
DATA COLLECTION AND ANALYSIS
We used standard Cochrane methodology to select studies, extract data and analyse results. One trial author provided additional data and clarification.
MAIN RESULTS
We identified one RCT, with 18 participants, that fulfilled the predetermined inclusion criteria. The trial compared plasma exchange to sham plasma exchange in participants with IgG or IgA paraproteinaemic neuropathy over a three-week follow-up period. We identified four other studies but these were not RCTs or quasi-RCTs. The included RCT did not report our predefined primary outcome measure, change in disability six months after randomisation. The trial revealed a modest benefit of plasma exchange in the weakness component of the Neuropathy Disability Score (NDS, now the Neuropathy Impairment Score); the mean improvement with plasma exchange was 17 points (95% confidence interval (CI) 5.2 to 28.8 points) versus 1 point (95% CI -7.7 to 9.7 points) in the sham exchange group at three weeks' follow-up (mean difference (MD) 16.00; 95% CI 1.37 to 30.63, low quality evidence). There was no statistically significant difference in the overall NDS (MD 18.00; 95% CI -2.03 to 38.03, low quality evidence), vibration thresholds or neurophysiological indices. Adverse events were not reported. The trial was at low risk of bias overall, although limitations of trial size and duration reduce the quality of the evidence in support of its conclusions.
AUTHORS' CONCLUSIONS
The evidence from RCTs for the treatment of IgG or IgA paraproteinaemic neuropathy is currently inadequate. More RCTs of treatments are required. These should have adequate follow-up periods and contain larger numbers of participants, perhaps through multicentre collaboration, considering the relative infrequency of this condition. Observational or open trial data provide limited support for the use of treatments such as plasma exchange, cyclophosphamide combined with prednisolone, intravenous immunoglobulin, and corticosteroids. These interventions show potential therapeutic promise but the potential benefits must be weighed against adverse effects. Their optimal use and the long-term benefits need to be considered and validated with well-designed RCTs.

Meta-Analysis
IMPORTANCE
Several trials demonstrated the impact of novel agent-based maintenance in newly diagnosed multiple myeloma (NDMM), but there is no current evidence demonstrating the superiority of one regimen over the other, owing to the lack of direct/indirect comparisons.
OBJECTIVE
To analyze and compare the effectiveness of different maintenance regimens in NDMM via a network meta-analysis.
DATA SOURCES
We performed 2 independent searches in PubMed and Cochrane databases, and then we identified all the records registered after 1999 and on or before November 20, 2017.
STUDY SELECTION
By blinded review, we identified prospective phase 3 randomized trials evaluating novel agent-based maintenance in patients with NDMM; the included studies compared at least 2 maintenance approaches; comparators included placebo and no maintenance. From 364 screened records, 11 studies were included.
DATA EXTRACTION AND SYNTHESIS
We followed (independent extraction) the guidelines provided by the PRISMA Report and the EQUATOR Network. The evidence was synthesized using a network meta-analysis (NMA). To allow comparison of all treatments, no maintenance was selected as common comparator and the effect of placebo was assumed to be the same as no treatment. The best option was identified by a Bayesian consistency model based on hazard ratio (HR), 95% credible interval (CrI), probability of being the best treatment (PbBT), and median ranking distribution (MedR).
MAIN OUTCOMES AND MEASURES
Outcomes of interest were progression-free survival (PFS) and overall survival (OS).
RESULTS
Eleven trials and 8 treatments including a total of 5073 participants were included. By PFS analysis, lenalidomide-based regimens (lenalidomide-prednisone, lenalidomide alone) were identified as the most effective options (HR, 0.39 [95% CrI, 0.28-0.53] and 0.47 [95% CrI, 0.39-0.55], respectively; MedR, 1 and 2; overall PbBT, 74%). Four treatments (thalidomide-interferon, thalidomide-bortezomib, bortezomib-prednisone, thalidomide alone) showed an HR in favor of maintenance. By OS analysis, lenalidomide alone was identified as the best option (HR, 0.76; 95% CrI, 0.51-1.16; MedR, 2; PbBT, 38%), followed by bortezomib-thalidomide and bortezomib-prednisone. Similar features were noticed in the restricted network including transplant trials, in the sensitivity analysis, and in most of the prognostic subgroups.
CONCLUSIONS AND RELEVANCE
Based on PFS and OS results of this NMA, lenalidomide maintenance appears to be the best treatment option, by synthesizing the available evidence of novel agent-based maintenance in the past 20 years.

Meta-Analysis
Comparison of denosumab and zoledronic acid for the treatment of solid tumors and multiple myeloma with bone metastasis: a systematic review and meta-analysis based on randomized controlled trials.
OBJECTIVE
To compare the efficacy and safety between denosumab and zoledronic acid for advanced cancer with bone metastasis.
METHODS
MEDLINE, EMBASE, and the Cochrane library databases were searched for randomized controlled trials up to December 2020 that compared denosumab and zoledronic acid in the treatment of advanced cancer with bone metastasis. The following clinical outcomes were extracted for analysis: time to first skeletal-related event, time to first-and-subsequent skeletal-related events, overall survival, and disease progression. Safety outcomes including incidence of adverse events, serious adverse events, acute-phase reactions, renal toxicity, osteonecrosis of the jaw, and hypocalcemia were also extracted.
RESULTS
Four randomized controlled trials involving 7201 patients were included. The overall analysis showed that denosumab was superior to zoledronic acid in delaying time to first skeletal-related event (hazard ratio = 0.86; 95% confidence interval, 0.80-0.93; P < 0.01) and time to first-and-subsequent skeletal-related events (risk ratio 0.87; 95% confidence interval 0.81-0.93; P < 0.01). Denosumab was associated with lower incidence of renal toxicity (risk ratio 0.69; 95% confidence interval 0.54-0.87; P < 0.01) and acute phase reaction (risk ratio 0.47; 95% confidence interval 0.38-0.56; P < 0.01), but higher incidence of hypocalcemia (risk ratio 1.78; 95% confidence interval 1.33-2.38; P < 0.01) and osteonecrosis of the jaw (risk ratio 1.41; 95% confidence interval 1.01-1.95; P = 0.04). No significant differences were found in overall survival, time to disease progression, or incidence of adverse events and serious adverse events between denosumab and zoledronic acid.
CONCLUSIONS
Compared with zoledronic acid, denosumab is associated with delayed first-and-subsequent skeletal-related events, lower incidence of renal toxicity, and acute phase reaction, but higher incidence of hypocalcemia and osteonecrosis of the jaw. Hence, denosumab seems to be a promising choice for advanced cancer with bone metastasis. Nonetheless, more randomized controlled trials are needed for further evaluation.

Meta-Analysis Review
During the past decades, many novel agents have improved response and survival of patients with multiple myeloma. Nevertheless, it remains challenging when they suffer relapsing. Thus, novel therapeutic agents are needed. We aimed to assess the efficacy and safety of a novel agent panobinostat for patients with relapsed or/and refractory MM. A systematic literature review identified studies for clinical trials about panobinostat in patients with relapsed or/and refractory MM. We searched studies published between January 2000 and December 2015 in Pubmed, Ovid, EBSCO and the Cochrane library. Random-effect pooled estimates were calculated for overall response rate and rates of common adverse effects. The results showed 11 clinical trials including 700 patients with relapsed or/and refractory MM treated with panobinostat were identified. The ORR varied between 0.08 and 0.67. Pooled analyses showed the results that the ORR was 0.45 (95% CI: 0.31-0.59, I(2) = 90.5%, P = 0.000) for panobinostat combined with any other kind of drugs. The most common Grade3/4 adverse effects were thrombocytopenia, neutropenia, lymphopenia, anemia, diarrhea, fatigue, nausea and so on. In conclusion, based on our analyses, the regimen of panobinostat combining with other agents seems to be well tolerated and efficacious in patients with relapsed or/and refractory MM.

Meta-Analysis
BACKGROUND
Upfront high-dose therapy (HDT) followed by autologous stem cell transplantation (ASCT) remains a profitable strategy for newly diagnosed multiple myeloma (MM) patients in the context of novel agents. However, current knowledge demonstrates a discrepancy between progression-free survival (PFS) and overall survival (OS) benefit with HDT/ASCT.
METHODS
We conducted a systematic review and meta-analysis that included both randomized controlled trials (RCTs) and observational studies evaluating the benefit of upfront HDT/ASCT published during 2012 to 2023. Further sensitivity analysis and meta-regression were also performed.
RESULTS
Among the 22 enrolled studies, 7 RCTs and 9 observational studies had a low or moderate risk of bias, while the remaining 6 observational studies had a serious risk of bias. HDT/ASCT revealed advantages in complete response (CR) with an odds ratio (OR) of 1.24 and 95% confidence interval (CI) 1.02 ~ 1.51, PFS with a hazard ratio (HR) of 0.53 (95% CI 0.46 ~ 0.62), and OS with an HR of 0.58 (95% CI 0.50 ~ 0.69). Sensitivity analysis excluding the studies with serious risk of bias and trim-and-fill imputation fundamentally confirmed these findings. Older age, increased percentage of patients with International Staging System (ISS) stage III or high-risk genetic features, decreased proteasome inhibitor (PI) or combined PI/ immunomodulatory drugs (IMiD) utilization, and decreased follow-up duration or percentage of males were significantly related to a greater survival advantage with HDT/ASCT.
CONCLUSIONS
Upfront ASCT remains a beneficial treatment for newly diagnosed MM patients in the period of novel agents. Its advantage is especially acute in high-risk MM populations, such as elderly individuals, males, those with ISS stage III or high-risk genetic features, but is attenuated with PI or combined PI/IMiD utilization, contributing to divergent survival outcomes.

Meta-Analysis
This systematic review and meta-analysis rigorously examines the relationship between glyphosate exposure and risk of lymphohematopoietic cancer (LHC) including NHL, Hodgkin lymphoma (HL), multiple myeloma (MM), and leukemia. Meta-relative risks (meta-RRs) were positive and marginally statistically significant for the association between any versus no use of glyphosate and risk of NHL (meta-RR = 1.3, 95% confidence interval (CI) = 1.0-1.6, based on six studies) and MM (meta-RR = 1.4, 95% CI = 1.0-1.9; four studies). Associations were statistically null for HL (meta-RR = 1.1, 95% CI = 0.7-1.6; two studies), leukemia (meta-RR = 1.0, 95% CI = 0.6-1.5; three studies), and NHL subtypes except B-cell lymphoma (two studies each). Bias and confounding may account for observed associations. Meta-analysis is constrained by few studies and a crude exposure metric, while the overall body of literature is methodologically limited and findings are not strong or consistent. Thus, a causal relationship has not been established between glyphosate exposure and risk of any type of LHC.

IMPORTANCE
Necrobiotic xanthogranuloma (NXG) is a non-Langerhans cell histiocytosis classically associated with paraproteinemia attributable to plasma-cell dyscrasias or lymphoproliferative disorders. Despite the morbidity of NXG, the literature is limited to case reports and small studies, and diagnostic criteria are lacking.
OBJECTIVE
To evaluate the characteristics of NXG and propose diagnostic criteria.
DESIGN, SETTING, AND PARTICIPANTS
This multicenter cross-sectional study was conducted at tertiary academic referral centers and followed by a systematic review and a consensus exercise. The multicenter cohort included patients with NXG diagnosed at the Brigham and Women's and Massachusetts General Hospitals (2000-2018), the University of Iowa Hospitals and Clinics (2000-2018), and the University of Pennsylvania Health System (2008-2018). The systematic review was conducted in 2018 and included patients with NXG identified in the Cochrane, Ovid EMBASE, PubMed, and Web of Science databases. The consensus exercise was conducted by 8 board-certified dermatologists to identify diagnostic criteria.
MAIN OUTCOMES AND MEASURES
Demographic factors, comorbidities, clinical features, and treatment response.
RESULTS
Of 235 included patients with NXG (34 from the multicenter cohort and 201 from the systematic review results), the mean (SD) age at presentation was 61.6 (14.2) years; 147 (62.6%) were female. Paraproteinemia was detected in 193 patients (82.1%), most often IgG-κ (117 patients [50.0%]). A malignant condition was detected in 59 patients (25.1%), most often multiple myeloma (33 patients [14.0%]). The overall rate of paraproteinemia and/or a malignant condition was 83.8% (197 patients). In the multicenter cohort, evolution of paraproteinemia into multiple myeloma was observed up to 5.7 years (median [range], 2.4 [0.1-5.7] years) after NXG presentation. Cutaneous lesions consisted of papules, plaques, and/or nodules, typically yellow or orange in color (113 of 187 [60.4%]) with a periorbital distribution (130 of 219 [59.3%]). The eye was the leading site of extracutaneous involvement (34 of 235 [14.5%]). In the multicenter cohort, intravenous immunoglobulin had the best treatment response rate (9 of 9 patients [100%]), followed by antimalarial drugs (4 of 5 patients [80%]), intralesional triamcinolone (6 of 8 patients [75%]), surgery (3 of 4 patients [75%]), chemotherapy (8 of 12 patients [67%]), and lenalidomide or thalidomide (5 of 8 patients [63%]). The consensus exercise yielded 2 major criteria, which were (1) clinical and (2) histopathological features consistent with NXG, and 2 minor criteria, consisting of (1) paraproteinemia, plasma-cell dyscrasia, and/or other associated lymphoproliferative disorder and (2) periorbital distribution of cutaneous lesions. In the absence of foreign body, infection, or another identifiable cause, fulfillment of both major and at least 1 minor criterion were proposed to establish the diagnosis of NXG.
CONCLUSIONS AND RELEVANCE
Necrobiotic xanthogranuloma is a multisystem disorder associated with paraproteinemia and malignant conditions. The proposed diagnostic criteria may advance clinical research and should be validated.

PURPOSE
The globalization of clinical trials has accelerated recent advances in multiple myeloma (MM). However, it is unclear whether trial enrollment locations are reflective of the global burden of MM and whether access to novel therapies is timely and equitable for countries that participate in those trials.
METHODS
To assess this, we characterized where MM trials that led to US Food and Drug Administration (FDA) approvals were conducted and determined how often and quickly these drug regimens received approval in their participating trial countries on the basis of country income level and geographic region.
RESULTS
A systematic review was conducted to identify all MM clinical trials that met their primary endpoint, enrolled patients outside the United States, and resulted in FDA approval from 2005 to 2019. A total of 18 pivotal MM clinical trials were identified. High-income countries enrolled patients in 100% (18/18) of the trials identified, whereas upper-middle and lower-middle-income countries were represented in 61% (11/18) and 28% (5/18) of trials, respectively. No patients from low-income countries were enrolled. One trial enrolled patients in sub-Saharan Africa, and no trials enrolled patients in South Asia/Caribbean. For drugs/regimens that were approved in their participating countries, the median time from FDA approval to approval was 10.9 months. There were no drugs approved in lower-middle-income trial countries. MM trials leading to FDA approval are generally run in high-income, European, and Central Asian countries.
CONCLUSION
There are substantial disparities in where novel therapies are evaluated and where they are ultimately approved for use on the basis of income level and geography.

Meta-Analysis
The efficacy and safety of lenalidomide in the treatment of multiple myeloma patients after allo-hematopoietic stem-cell transplantation: a systematic review and meta-analysis.
BACKGROUND
There has been long-standing controversy regarding the effectiveness and safety of lenalidomide as a maintenance treatment for patients with multiple myeloma (MM) after allogeneic cell transplantation. This meta-analysis aimed to explore the effectiveness and safety of lenalidomide in the maintenance treatment of MM patients after allogeneic cell transplantation based on published data.
METHODS
A systematic review and meta-analysis was conducted in English and Chinese databases, covering all available publications until 1 December 2020. Statistical analysis was performed using the software STATA 14.0, and odds ratios (ORs) combined with 95% confidence intervals (CIs) were calculated to explore the efficacy and safety of lenalidomide in the treatment of MM patients after allogeneic cell transplantation.
RESULTS
A total of 173 MM cases in 8 independent studies from 2007 to 2014 were included. Through a single-arm meta-analysis of the disease status of MM patients after lenalidomide treatment, 3.6% of patients were in minimal response (MR, P=0.006), 39.0% were in complete remission (CR, P=0.169), 20.2% in partial remission (PR, P<0.001), 12.8% in very good partial remission (VGPR, P=0.049), and 9.7% in SD (P=0.023); the PD was 5.6% (P=0.010). Through meta-analysis of adverse reactions after taking lenalidomide, 35.3% (P=0.628) of participants developed acute graft-versus-host disease (GVHD); 22.6% (P=0.049) developed chronic GVHD; 20.3% (P=0.001) developed infection; 22.5% (P=0.352) had thrombocytopenia; 32.5% (P<0.000) had neutropenia; pain occurred in 17.8% (P=0.350) of patients, and peripheral neuropathy occurred in 17.8% (P=0.995) of participants. The overall survival (OS) of ≥2 years and progression-free survival (PFS) of ≥2 years of MM patients after allo-hematopoietic-stem-cell transplantation (HSCT) taking lenalidomide were analyzed, and the results were 64.9% (P=0.049) and 58.4% (P=0.890), respectively.
DISCUSSION
Lenalidomide is effective in the treatment of MM patients after allo-HSCT, and reducing the incidence of infection and peripheral neuropathy, but it is not effective in reducing GVHD and blood system adverse reactions.

Review
AIMS
Reconstruction of the acetabulum after resection of a periacetabular malignancy is technically challenging and many different techniques have been used with varying success. Our aim was to prepare a systematic review of the literature dealing with these techniques in order to clarify the management, the rate of complications and the outcomes.
PATIENTS AND METHODS
A search of PubMed and MEDLINE was conducted for English language articles published between January 1990 and February 2017 with combinations of key search terms to identify studies dealing with periacetabular resection with reconstruction in patients with a malignancy. Studies in English that reported radiographic or clinical outcomes were included. Data collected from each study included: the number and type of reconstructions, the pathological diagnosis of the lesions, the mean age and follow-up, gender distribution, implant survivorship, complications, functional outcome, and mortality. The results from individual studies were combined for the general analysis, and then grouped according to the type of reconstruction.
RESULTS
A total of 57 studies met the inclusion criteria and included 1700 patients. Most lesions were metastatic (41%), followed by chondrosarcoma (29%), osteosarcoma (10%), Ewing's sarcoma (7%), and multiple myeloma (2%). The techniques of reconstruction were divided into seven types for analysis: those involving a Harrington reconstruction, a saddle prosthesis, an allograft and allograft prosthesis composite, a pasteurised autograft, a porous tantalum implant, a custom-made prosthesis and a modular hemipelvic reconstruction. The rate of complications was 50%, with infection (14%) and instability (8%) being the most common. Mortality data were available for 1427 patients (84%); 50% had died of disease progression, 23% were alive with disease, and 27% had no evidence of disease at a mean follow-up of 3.4 years (0 to 34).
CONCLUSION
Both the rate of complications and mortality are high following resection of oncological periacetabular lesions and reconstruction. Many types of reconstruction have been used with unique challenges and complications for each technique. Newer prostheses, including custom-made prostheses and porous tantalum implants and augments, have shown promising early functional and radiographic outcomes.
