Meta-Analysis Review
A registered (PROSPERO - CRD42022346462) systematic review and meta-analysis was conducted of all-grade infections amongst adult patients receiving CAR-T therapy for haematological malignancy. Meta-analysis of pooled incidence, using random effects model, was conducted. Cochran's Q test examined heterogeneity. 2678 patients across 33 studies were included in the primary outcome. Forty-percent of patients (95% CI: 0.33 - 0.48) experienced an infection of any grade. Twenty-five percent of infection events (95% CI: 0.16 - 0.34) were severe. Late infections were as common as early infections (IRR = 0.86, 95% CI: 0.38 - 1.98). All-grade infections, bacterial and viral infections were highest in myeloma patients at 57%, 37% and 28% respectively. Patients with NHL more commonly experienced late infections. Pooled rate of invasive candidiasis/yeast infections was 2% in studies utilizing anti-yeast prophylaxis. This review identified a high rate of all-grade infections, moderate rate of severe infections, and myeloma as a high-risk haematological group.

BACKGROUND
Amyloid light-chain (AL) amyloidosis is an ultra-rare disease associated with significant morbidity and mortality. Few studies have examined the global epidemiology of this condition.
METHODS
This study estimated the diagnosed incidence and 1-year, 5-year, 10-year, and 20-year period prevalence of AL amyloidosis in 2018 for countries in and near Europe, and in the United States (US), Canada, Brazil, Japan, South Korea, Taiwan, and Russia. A systematic literature review (SLR) was conducted to identify country-specific, age- and gender-specific diagnosed incidence of AL amyloidosis and observed survival data-point inputs for an incidence-to-prevalence model. Extrapolations were used to estimate incidence and prevalence for countries without registry or published epidemiological data.
RESULTS
Of 171 publications identified in the SLR, 10 records met the criteria for data extraction, and two records were included in the final incidence-to-prevalence model. In 2018, an estimated 74,000 AL amyloidosis cases worldwide were diagnosed during the preceding 20 years. The estimated incidence and 20-year prevalence rates were 10 and 51 cases per million population, respectively.
CONCLUSIONS
Orphan medicinal product designation criteria of the European Medicines Agency or Electronic Code of Federal Regulations indicate that a disease must not affect > 5 in 10,000 people across the European Union or affect < 200,000 people in the US. This study provides up-to-date epidemiological patterns of AL amyloidosis, which is vital for understanding the burden of the disease, increasing awareness, and to further research and treatment options.

Meta-Analysis
Rituximab-based chemo-immunotherapy is currently the standard first-line treatment for Waldenstrom macroglobulinaemia (WM), while ibrutinib has emerged as an alternative. In the absence of randomised trials (RCTs) comparing these regimens, the optimal first-line treatment for WM remains uncertain. In this systematic review and meta-analysis, we sought to assess the efficacy and safety of first-line treatment regimens for WM. We searched key databases from January 2007 to March 2023, including phase II and III trials, including treatment-naïve WM patients treated with rituximab-based regimens or ibrutinib. Response rates, progression-free survival (PFS), overall survival (OS), and toxicities were evaluated. Four phase III and seven phase II trials were included among 736 unique records. Pooled response rates from all comparative and non-comparative trials were 46%, 33% and 26% for bendamustine rituximab (BR), bortezomib-dexamethasone, cyclophosphamide, rituximab (BDRC) and ibrutinib rituximab (IR), respectively. Two-year pooled PFS was 89%, 81% and 82% with BR, BDRC and IR, respectively. Neuropathy was more frequent with bortezomib, while haematologic and cardiac toxicities were more common with chemo-immunotherapy and ibrutinib-based regimens respectively. Our findings suggest that BR yields higher response rates than bortezomib or ibrutinib-based combinations. RCTs comparing BR against emerging therapies, including novel Bruton Tyrosine Kinase Inhibitors, are warranted.

Review
Necrobiotic xanthogranuloma (NXG) is an uncommon non-Langerhans cell histiocytosis involving skin and extracutaneous tissues. The lesions are usually asymptomatic and commonly appear in the periorbital area. Paraproteinemia is closely associated with NXG and its pathogenesis remains unclear. NXG prognosis is poor with several treatments showing variable results. Treatment of monoclonal gammopathy with alkylating agents does not necessarily influence the activity of the skin disease and vice versa. The aim of this systematic review is to summarize all reported treatments of necrobiotic xanthogranuloma of the skin, with or without underlying malignant condition and based on articles from the PubMed database using the query 'necrobiotic xanthogranuloma treatment', both in English and German, about 'human' subjects and published between 1980 and 2014, documenting adequate treatment for NXG. Mainly individual case reports, small case series and retrospective studies were found. Treatment options include topical and systemic corticosteroids, thalidomide, high-dose intravenous immunoglobulin (IVIG), chlorambucil, cyclophosphamide, fludarabine, rituximab, melphalan, infliximab, interferon alpha, cladribine, hydroxychloroquine, azathioprine, methotrexate, laser therapy, radiotherapy, surgery, PUVA, plasmapheresis and extracorporeal photopheresis. Randomized controlled trials and studies on long-term outcomes after treatment were not found and are necessary to focus on in the future.

Review
OBJECTIVES
This integrative review describes the genomic variants that have been found to be associated with poor prognosis in patients diagnosed with multiple myeloma (MM). Second, it identifies MM genetic and genomic changes using next-generation sequencing, specifically whole-genome sequencing or exome sequencing.
DATA SOURCE
A search for peer-reviewed articles through PubMed, EBSCOhost, and DePaul WorldCat Libraries Worldwide yielded 33 articles that were included in the final analysis.
CONCLUSION
The most commonly reported genetic changes were KRAS, NRAS, TP53, FAM46C, BRAF, DIS3, ATM, and CCND1. These genetic changes play a role in the pathogenesis of MM, prognostication, and therapeutic targets for novel therapies.
IMPLICATIONS FOR NURSING PRACTICE
MM genetics and genomics are expanding rapidly; oncology nurse clinicians must have basic competencies in genetics and genomics to help patients understand the complexities of genetic and genomic alterations and be able to refer patients to appropriate genomic professionals if needed.

Meta-Analysis Review
Bisphosphonates (BPs) and denosumab (DENOS), due to their ability to inhibit osteoclast activity, are used to prevent skeletal complications in multiple myeloma (MM) patients. The NCBI PubMed, Web of Science, Scopus and ClinicalTrials.gov databases, were systematically searched for interventional studies, assessing the use of BP and DENOS in MM patients. Overall survival, disease progression, skeletal-related events, bone pain, osteonecrosis of the jaw (ONJ) and renal toxicity were the outcomes of interest. A total of 993 studies were retrieved and 43 were used for qualitative synthesis. Clodronate (CLOD) and zoledronic acid (ZOL) were effective in reducing skeletal complications compared to placebo. Results are mixed regarding the efficacy of pamidronate in reducing skeletal related events. ONJ rates were higher for ZOL, but under 5%, with CLOD having the safest profile. DENOS demonstrated non-inferiority to ZOL, in improving overall survival [pooled Hazard Ratio(HR) 1.02(95% CI 0.72,1.44)], progression free survival [pooled HR 0.92(95% CI 0.76,1.11)] and in reducing skeletal related events [pooled HR 1.03(95% CI 0.92,1.16)], with similar rates of ONJ and better safety profile regarding renal toxicity. Denosumab has comparable efficacy and safety with ZOL and may even replace BPs in the future, in the management of myeloma bone disease.

BACKGROUND
Amyloidosis is a disease characterized by the progressive deposition of abnormal proteins that can occur in any organ. In the oral cavity, the tongue is the most common affected site, usually causing macroglossia. Biopsy is essential for the diagnosis and the occurrence of its systemic form is mandatory to be investigated. This systematic review evaluated the existing information in the literature on Amyloidosis in the oral cavity to allow a more comprehensive and updated analysis of its clinicopathological characteristics, as well as to explore the main forms of treatment and prognostic factors.
MATERIAL AND METHODS
Electronic searches were undertaken in five databases supplemented by manual scrutiny.
RESULTS
A total of 111 studies were included with 158 individuals.
CONCLUSIONS
The disease had a higher prevalence in women, the tongue was the most affected site, as well as the systemic form of the disease. The worst prognosis was for cases of systemic amyloidosis associated with multiple myeloma.

Review
Treatment of amyloid light-chain (AL) amyloidosis, a rare disease with a <5-year lifespan, remains challenging. This systematic literature review (SLR) aimed to evaluate the current evidence base in AL amyloidosis. Literature searches on clinical, health-related quality of life, economic and resource use evidence were conducted using the Embase, MEDLINE and Cochrane databases as well as gray literature. This SLR yielded 84 unique studies from: five randomized controlled trials; 54 observational studies; 12 health-related quality of life studies, none with utility values; no economic evaluation studies; and 16 resource use studies, none with indirect costs. This SLR highlights a paucity of published literature relating to randomized controlled trials, utility values, economic evaluations and indirect costs in AL amyloidosis.

Review
Priapism is defined as a persistent penile erection lasting more than 4 h. We searched the literature for reviews, case reports, and series for patients with lymphoproliferative disorders who developed priapism. The search involved all the lymphoproliferative disorders included in the revised 2016 World Health Organization classification of lymphoid neoplasms including chronic lymphocytic leukemia, multiple myeloma, Waldenström macroglobulinemia, and lymphomas. A total of 16 articles were found. The search included cases up to 4 January 2021. Priapism was seen most commonly as the first manifestation of lymphoproliferative disorders, rarely seen after treatment or after diagnosis.

Review
The correlation between response and survival has not been well-studied in relapsed or refractory multiple myeloma (RRMM). A systematic literature review of Medline, Embase and Cochrane databases (2010-06/2020) and relevant congresses (2018-2020) was performed to identify randomized clinical trials in RRMM reporting median overall survival (mOS), progression-free survival and response end points. The relationship between mOS and response end points was analyzed using Pearson's product-moment correlation. A total of 81 records for 65 original studies, representing 12,827 patients were included. The correlation was moderate for mOS with overall response rate (Pearson r = 0.79), very good partial response (r = 0.73) and duration of response (r = 0.78); all were statistically significant. In linear regression models, estimated mOS gain was 0.48, 0.47 and 1.94 months per percentage point of overall response rate, very good partial response and complete response, respectively (all p < 0.001). Significance was maintained after adjustment for age, relapsed versus refractory multiple myeloma and study year. The analysis was limited by small sample sizes and inconsistent reporting of study-level covariates. These findings support short-term response-based end points as surrogates to survival in RRMM.
