OBJECTIVE
Multiple myeloma (MM) is a bone marrow cancer that profoundly affects plasma cells involved in the immune response. Myeloma cells alter the average production of cells in the bone marrow. Anti-B-cell maturation antigen (BCMA) chimeric antigen receptor (CAR) T-cell therapy allows genetic modifications of an individual's T-cells to increase the expression of CARs used to identify and attach BCMA proteins to the malignant cells. Our main objective is to perform a systematic review and meta-analysis to explore the efficacy and safety of anti-BCMA CAR T-cell therapy for MM.
MATERIAL AND METHODS
We searched five databases, PubMed, CNKI, EMBASE, Cochrane, Web of Science, and CNKI, for studies published on anti-BCMA,CAR-T-cell treatment for MM. Inclusion criteria involved prospective single-arm studies either single or multi-center, in various MM phases and studies that reported anti-BCMA,CAR-T-cell treatment for MM. We excluded non-English publications and conference papers. All statistical analyses were performed in R software and Review Manager 5.4.1.
RESULTS
Thirteen articles were included in the analysis. We found that the overall response survival complete response increase was statistically significant. Similarly, the reduction in cytokine release syndrome grades 3 and 4 and neurotoxicity after follow-up was statistically significant. However, the reduction in minimal residual disease negativity (MRDN) was not statistically significant.
CONCLUSION
Using anti-BCMA CAR T-cell therapy in MM was highly efficacious and safe in lowering the adverse outcomes and improving the survival outcomes, complete response, and overall response.

Review
We conducted a comprehensive investigation to explore the pathological expression of the CXCR4 receptor in lymphoproliferative disorders (LPDs) using [Ga]Ga-Pentixafor PET/CT or PET/MRI technology. The PICO question was as follows: What is the diagnostic role (outcome) of [Ga]Ga-Pentixafor PET (intervention) in patients with LPDs (problem/population)? The study was written based on the reporting items for systematic reviews and meta-analyses (PRISMA) 2020 guidelines, and it was registered on the prospective register of systematic reviews (PROSPERO) website (CRD42024506866). A comprehensive computer literature search of Scopus, MEDLINE, Scholar, and Embase databases was conducted, including articles indexed up to February 2024. To the methodological evaluation of the studies used the quality assessment of diagnosis accuracy studies-2 (QUADAS-2) tool. Of the 8380 records discovered, 23 were suitable for systematic review. Fifteen studies (on 571 LPD patients) focused on diagnosis and staging, and eight trials (194 LPD patients) assessed treatment response. The main conclusions that can be inferred from the published studies are as follows: (a) [Ga]Ga-Pentixafor PET may have excellent diagnostic performance in the study of several LPDs; (b) [Ga]Ga-Pentixafor PET may be superior to [F]FDG or complementary in some LPDs variants and settings; (c) multiple myeloma seems to have a high uptake of [Ga]Ga-Pentixafor. Overall, this technique is probably suitable for imaging, staging, and follow-up on patients with LPD. Due to limited data, further studies are warranted to confirm the promising role of [Ga]Ga-Pantixafor in this context.

Review
BACKGROUND
Peripheral neuropathy (PN) is a prevalent complication of multiple myeloma (MM), due to the disease itself or its treatment. Despite extensive research, the optimal treatment for multiple myeloma peripheral neuropathy (MMPN) remains unclear. Clinical practice has shown the potential efficacy of acupuncture in managing MMPN. This study aimed to conduct a comprehensive analysis of the literature to assess the effectiveness and safety of acupuncture as a treatment for MMPN.
METHODS
The PubMed, Web of Science, MEDLINE, Cochrane Library, and Embase databases were comprehensively searched from inception to November 1, 2023 to identify relevant studies pertaining to the use of acupuncture to treat MMPN.
RESULTS
A total of five studies, encompassing 97 patients diagnosed with drug-related PN, were ultimately included in this analysis. The literature lacks any reports pertaining to the utilization of acupuncture for disease-related PN. ST36, LI4, SP6, and EX-LE-10 were found to be the most frequently chosen acupoints. Following acupuncture treatment, there was a consistent reduction in scores on the Visual Analogue Scale (VAS), Neuropathic Pain Scale (NPS), Brief Pain Inventory-Short Form (BPI-SF), and Functional Assessment of Cancer Therapy/Gynecologic Oncology Group-Neurotoxicity (FACT/GOG-Ntx) among MMPN patients. The results of Nerve Conduction Velocity (NCV) tests yielded conflicting results. No severe adverse effects were reported.
CONCLUSION
The use of acupuncture for disease-related PN has not been studied to date. Acupuncture is safe for drug-related PN and is helpful for relieving pain. But uncertainty exists regarding the efficacy of this approach because there is substantial heterogeneity with respect to acupuncture treatment regimens, and more high-quality studies on this topic are warranted.

The Impact of Outpatient versus Inpatient Administration of CAR-T Therapies on Clinical, Economic, and Humanistic Outcomes in Patients with Hematological Cancer: A Systematic Literature Review.
Although chimeric antigen receptor (CAR)-T cell therapies are typically administered in the inpatient setting, outpatient administration is rapidly expanding. However, there is limited summarized evidence comparing outcomes between outpatient and inpatient administration. This systematic literature review aims to compare the safety, efficacy, quality of life (QoL), costs, and healthcare resource utilization (HCRU) outcomes in patients with hematological cancer who are administered CAR-T therapy in an outpatient versus an inpatient setting. Publications (2016 or later) that reported the outcomes of interest in patients treated with a CAR-T therapy in both outpatient and inpatient settings, or only the outpatient setting, were reviewed. In total, 38 publications based on 21 studies were included. Safety findings suggested the comparable frequency of adverse events in the two settings. Eleven studies that reported data in both settings showed comparable response rates (80-82% in outpatient and 72-80% in inpatient). Improvements in the QoL were observed in both settings while costs associated with CAR-T therapy were lower in the outpatient setting. Although unplanned hospitalizations were higher in the outpatient cohort, overall HCRU was lower. Outpatient administration of CAR-T therapy appears to have comparable outcomes in safety, efficacy, and QoL to inpatient administration while reducing the economic burden.

Multiple myeloma (MM) accounts for 10% of hematologic cancers in the U.S.; however, incidence and mortality occur disproportionately between racial groups in real-world settings. Our study's objective was to systematically characterize the disparities in overall survival (OS) among Black and White patients with MM in the US using real-world evidence studies. A systematic literature review was undertaken by searching Embase and MEDLINE for observational studies conducted in the US, published between January 1, 2015 and October 25, 2021, and reporting OS for Black and White patients with MM. Records were reviewed by 2 independent researchers. OS data were extracted as hazard ratios (HR), median survival, or %, with methods of adjustment, as reported. Evidence quality was assessed by data source, population, and variables for which HRs for risk of death were adjusted. We included 33 US studies comprising 410,086 patients (21.5% Black; 78.5% White) with MM. Receipt of treatment varied; however, most studies reported that patients either underwent stem cell transplant and/or received systemic therapy. HRs from 9 studies were considered "high quality" by comparing nationally representative, generalizable cohorts and adjusting for key prognostic, treatment, and/or socioeconomic factors. After adjustment, these data suggested that Black patients exhibit similar or superior survival outcomes compared with their White counterparts. When data are adjusted for important confounders, Black patients exhibit better or equal survival to White patients, indicating that similarities in patient populations and equal access to treatment can bridge the disparity in patient outcomes between races.

Breast cancer is a growing disease, with a high worldwide incidence and mortality rate among women. Among the various types, the treatment of triple-negative breast cancer (TNBC) remains a challenge. Considering the recent advances in cold atmospheric plasma (CAP) cancer research, our goal was to evaluate efficacy data from studies based on chemotherapy and CAP in TNBC cell lines and animal models. A search of the literature was carried out in the PubMed, Web of Science, Cochrane Library, and Embase databases. Of the 10,999 studies, there were fifty-four in vitro studies, three in vivo studies, and two in vitro and in vivo studies included. MDA-MB-231 cells were the most used. MTT, MTS, SRB, annexin-V/propidium iodide, trypan blue, and clonogenic assay were performed to assess efficacy in vitro, increasing the reliability and comprehensiveness of the data. There was found to be a decrease in cell proliferation after both chemotherapy and CAP; however, different protocol settings, including an extensive range of drug doses and CAP exposure times, were reported. For both therapies, a considerable reduction in tumor volume was observed in vivo compared with that of the untreated group. The treatment of TNBC cell lines with CAP proved successful, with apoptosis emerging as the predominant type of cellular death. This systematic review presents a comprehensive overview of the treatment landscape in chemotherapy and CAP regarding their efficacy in TNBC cell lines.

BACKGROUND
Globally, multiple myeloma (MM) ranks 24 among the most common cancers. The Middle East and Africa are affected by an increasing trend in MM incidence, owing to several underlying factors. This systematic review aims to assess the epidemiology, patient characteristics, and treatment outcomes associated with MM in selected countries in the Middle East and Africa.
METHODS
An electronic search was performed in the PubMed/MEDLINE database. Abstracts presented at the annual meetings of the American Society of Clinical Oncology, American Society of Hematology, and European Society for Medical Oncology and the GLOBOCAN registry were searched. Qualitative analysis was performed.
RESULTS
A total of 412 articles were screened, and 14 were selected. The five-year prevalence per 100,000 gathered from country-wise GLOBOCAN data ranged between 155 in Kuwait and 5,625 in North Africa. The identified treatment options were proteasome inhibitors such as bortezomib, drugs such as thalidomide, lenalidomide, dexamethasone, melphalan, and cyclophosphamide, and newer drugs such as daratumumab.
CONCLUSION
Improved diagnostic capability has increased the incidence of MM in this region. However, advanced drugs and treatment regimens remain unaffordable in many countries of these regions. Therefore, understanding the trends of the disease and improving healthcare settings are imperative.

OBJECTIVE
To review biochemical parameters, clinical characteristics, demographics, radiological and histopathological findings, treatment modalities and outcomes used to examine patients with coexisting multiple myeloma and prostate adencocarcinoma.
METHODS
The systematic review comprised search on PubMed, Google Scholar, Science Direct and the Directory of Open Access Journal databases for case reports published till June 1, 2022. The search was done in line with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines using appropriate key words. Case reports included were those dealing exclusively with human subjects, were published in the English language and had free, full-text, public access. Quality assessment was done using Joanna Briggs Institute's Critical Appraisal Checklist for Case Reports. Data was extracted and the case reports were evaluated for demographic, diagnostic and treatment parameters.
RESULTS
Of the 515 studies initially identified, 5(0.97%) were analysed; all males with mean age 68.6±10.78 years. The most common symptom reported at presentation was low back pain 3(60%), Osteolytic lesions were seen in 4(80%) patients on imaging with elevated prostate surface antigen levels. Anaemia was found in 3(60%) patients and 2(40%) had thrombocytopenia.
CONCLUSION
Multiple myeloma and prostate adenocarcinoma can coexist although it is rare. Awareness regarding the possible coexistence of the two prominent cancer types may further help clinicians during their practice in considering multiple myeloma as a differential diagnosis when encountered with patients having osteolytic bony lesions along with elevated levels of prostate-specific antigen.

Review
BACKGROUND
The possibility of developing a severe coronavirus infectious (COVID-19) disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has increased, particularly in patients with hematological malignancies. These patients are more likely to produce less antibody protection due to the immunocompromised nature of the disease and the anticancer treatments. Therefore, the present systematic review intended to evaluate the seroconversion rate of COVID-19 vaccines in patients with hematological malignancies compared with healthy controls.
METHODS
A comprehensive systematic search was conducted in Medline via PubMed, EMBASE, and the World Health Organization COVID-19 Research Database, as well as other searches (i.e., reference list from article search and manual searches), from December 2020 to May 2022. The outcome of interest included estimating the seroconversion rates following COVID-19 vaccination in patients with hematological malignancies and comparing them with those in healthy controls. After two-step screening, the data were extracted and the summary measures were calculated using a random-effects model.
RESULTS
A total of 39 articles regarding patients with hematological malignancies were included in the present review. After the first vaccine dose, these patients had considerably lower antibody response rates (37.0%) compared with healthy controls (74.5%). Following the second vaccine dose, the seroconversion rate in patients reached 66.8%, whereas it peaked at 97.9% in the healthy controls following complete immunization. Notably, the BNT162b2 and ChAdOx1 vaccine combination achieved the highest seropositivity rate of approximately 70%. Multiple myeloma, chronic lymphocytic leukemia, and lymphoma were the cancers of interest in most of the studies.
CONCLUSIONS
The results of the present study highlighted the comparatively low seropositivity rates in patients with hematological malignancies, with substantial variations in rates across disease groups. The findings emphasize the possibility of additional booster doses for these individuals to enhance their immunity against SARS-CoV-2.

IMPORTANCE
Published research suggests that patient-reported outcomes (PROs) are neither commonly collected nor reported in randomized clinical trials (RCTs) for solid tumors. Little is known about these practices in RCTs for hematological malignant neoplasms.
OBJECTIVE
To evaluate the prevalence of PROs as prespecified end points in RCTs of hematological malignant neoplasms, and to assess reporting of PROs in associated trial publications.
EVIDENCE REVIEW
All issues of 8 journals known for publishing high-impact RCTs (NEJM, Lancet, Lancet Hematology, Lancet Oncology, Journal of Clinical Oncology, Blood, JAMA, and JAMA Oncology) between January 1, 2018, and December 13, 2022, were searched for primary publications of therapeutic phase 3 trials for adults with hematological malignant neoplasms. Studies that evaluated pretransplant conditioning regimens, graft-vs-host disease treatment, or radiotherapy as experimental treatment were excluded. Data regarding trial characteristics and PROs were extracted from manuscripts and trial protocols. Univariable analyses assessed associations between trial characteristics and PRO collection or reporting.
FINDINGS
Ninety RCTs were eligible for analysis. PROs were an end point in 66 (73%) trials: in 1 trial (1%) as a primary end point, in 50 (56%) as a secondary end point, and in 15 (17%) as an exploratory end point. PRO data were reported in 26 of 66 primary publications (39%): outcomes were unchanged in 18 and improved in 8, with none reporting worse PROs with experimental treatment. Trials sponsored by for-profit entities were more likely to include PROs as an end point (49 of 55 [89%] vs 17 of 35 [49%]; P < .001) but were not significantly more likely to report PRO data (20 of 49 [41%] vs 6 of 17 [35%]; P = .69). Compared with trials involving lymphoma (18 of 29 [62%]) or leukemia or myelodysplastic syndrome (18 of 28 [64%]), those involving plasma cell disorders or multiple myeloma (27 of 30 [90%]) or myeloproliferative neoplasms (3 of 3 [100%]) were more likely to include PROs as an end point (P = .03). Similarly, compared with trials involving lymphoma (3 of 18 [17%]) or leukemia or myelodysplastic syndrome (5 of 18 [28%]), those involving plasma cell disorders or multiple myeloma (16 of 27 [59%]) or myeloproliferative neoplasms (2 of 3 [67%]) were more likely to report PROs in the primary publication (P = .01).
CONCLUSIONS AND RELEVANCE
In this systematic review, almost 3 of every 4 therapeutic RCTs for blood cancers collected PRO data; however, only 1 RCT included PROs as a primary end point. Moreover, most did not report resulting PRO data in the primary publication and when reported, PROs were either better or unchanged, raising concern for publication bias. This analysis suggests a critical gap in dissemination of data on the lived experiences of patients enrolled in RCTs for hematological malignant neoplasms.
