Meta-Analysis Review
Chimeric Antigen Receptor T-cell (CAR T-cell) therapy is an effective treatment for relapsed/refractory (R/R) large B cell lymphoma (LBCL). However, patients with central nervous system (CNS) lymphoma were excluded in most of the CAR T-cell therapy trials. This meta-analysis assesses the efficacy with CAR T-cell therapy in LBCL patients with CNS involvement. Two reviewers independently searched PubMed and Cochrane Library to identify all published literature associated with United States Food and Drug Administration approved CAR T-cell therapies for LBCL. Patients with CNS LBCL were included. Meta-analysis of proportion was performed to evaluate the overall response (ORR), complete response (CR) for efficacy, and cytokine release syndrome and immune effector cell-associated neurotoxicity syndrome for safety assessment. Nineteen studies were qualified for inclusion with 141 CNS LBCL patients. The ORR and CR rates were 61% and 55% respectively. The median overall survival (OS) was 8.8 months, and the median progression free survival (PFS) was 4.4 months. Severe immune effector cell-associated neurotoxicity syndrome (grade≥3) were reported in 25% (32/130) patients and severe cytokine release syndrome (grade≥3) were found in 10% (13/124) of the patients. The safety and efficacy of CAR T-cell therapy in CNS LBCL patients appears comparable to patients without CNS involvement.

INTRODUCTION
Adoptive cell therapy (ACT) is a rapidly evolving field. Patient-reported outcomes (PROs) allow patients to report the impact of treatment on their quality of life during and after treatment. The systematic review aims to characterise the breadth of PROs utilised in ACT cancer care and provide guidance for the use of PROs in this patient population in the future.
METHODS
A systematic search was conducted (MEDLINE, PsycINFO, Embase and CINAHL) in August 2021 by two reviewers. Search terms covered the following: "adoptive cell therapy", "patient-reported outcomes" and "cancer". Studies were included if they used a PRO measure to report the impact of ACT. The methodological quality of PROs was assessed. Forward and backward reference searching was conducted of any relevant papers. A quality grading scale was applied based on Cochrane and Revenson criteria for classification of high-quality studies. Key data from the studies and the included PROs was extracted by two researchers and tabulated.
RESULTS
One-hundred nine papers were identified; 11 papers were included. The majority of studies were single-arm trials or observational studies. Twenty-two different PROs were identified; none was ACT specific. The PROMIS-29 and EQ-5D were most commonly used. Few studies collected PRO data in the first 1-2 weeks. Four studies followed patients up for over a year, and a further four studies followed patients for approximately 3 months.
DISCUSSION
None of the PROs identified have been designed specifically for ACT. Appropriateness of existing instruments should be considered. It should be considered whether it is appropriate to collect data more frequently in the acute stage and then less frequently during follow-up. It should be considered if one tool is suitable at all time points or if the tool should be adapted depending on time since treatment. More research is needed to identify the exact timings of PRO assessments, and qualitative work with patients is needed to determine the most important issues for them throughout the treatment and follow-up.

Meta-Analysis
INTRODUCTION
Studies have compared chimeric antigen receptor (CAR) T-cell therapies and salvage chemotherapy in relapsed/refractory large B-cell lymphoma (LBCL) patients, but further evidence of their relative effectiveness is warranted.
METHODS
Our systematic review identified studies comparing efficacy and safety outcomes of axicabtagene ciloleucel (axi-cel), lisocabtagene maraleucel (liso-cel) and tisagenlecleucel (tisa-cel) trials to salvage chemotherapy cohorts in LBCL patients with ≥2 prior lines of treatment; and an extended evidence network included indirect comparisons comparing CAR T-cell therapies. We conducted network meta-analyzes using Bayesian hierarchical modeling.
RESULTS
Three studies comparing ZUMA-1 (axi-cel), TRANSCEND (liso-cel) and JULIET (tisa-cel) trials to salvage chemotherapy within the SCHOLAR-1 cohort were identified. Axi-cel (odds ratio [OR]:5.63; 95% credible interval [CrI]:2.66-12.42) and liso-cel (OR:4.26; 95%CrI:2.33-7.93) showed a significant increased overall response rate compared to tisa-cel, but not to one-another. Axi-cel demonstrated significant improvements in overall survival relative to liso-cel (hazard ratio [HR]:0.54; 95%CrI:0.37-0.79) and tisa-cel (HR:0.47; 95%CrI:0.26-0.88). Higher rates of grade ≥3 neurological events were observed with axi-cel than with tisa-cel and liso-cel.
CONCLUSIONS
We highlight important differences in clinical outcomes between CAR T-cell therapies. Axi-cel demonstrated improved overall survival compared to tisa-cel and liso-cel, and both axi-cel and liso-cel showed higher response rates compared to tisa-cel.

In the absence of randomized controlled trials comparing tisagenlecleucel vs. standard of care (SOC) in pediatric and young adult patients with relapsed or refractory acute lymphoblastic leukemia (r/r ALL), the objective was to compare the efficacy of tisagenlecleucel with historical controls from multiple disease registries using patient-level adjustment of the historical controls. The analysis is based on patient-level data of three tisagenlecleucel studies (ELIANA, ENSIGN and CCTL019B2001X) vs. three registries in Germany/Austria. Statistical analyses were fully pre-specified and propensity score weighting of the historical controls by fine stratification weights was used to adjust for relevant confounders identified by systematic literature review. Results showed high comparability of cohorts after adjustment with absolute SMD ≤ 0.1 for all pre-specified confounders and favorable outcomes for tisagenlecleucel compared to SOC for all examined endpoints. Hazard ratios for OS, EFS and RFS were 0.54 (95% CI: 0.41-0.71, p < 0.001), 0.67 (0.52-0.86, p = 0.001) and 0.77 (0.51-1.18, p = 0.233). The OS, EFS and RFS survival probability at 2 years was 59.49% for tisagenlecleucel vs. 36.16% for SOC population, 42.31% vs. 30.23% and 59.60% vs. 54.57%, respectively. Odds ratio for ORR was 1.99 (1.33-2.97, p < 0.001). Results for OS and ORR were statistically significant after adjustment for confounders and provide evidence supporting a superiority of tisagenlecleucel in r/r ALL given the good comparability of cohorts after adjustment for confounders.

A comprehensive bibliometric analysis (2000-2022) on the mapping of knowledge regarding immunotherapeutic treatments for advanced, recurrent, or metastatic cervical cancer.
BACKGROUND
Despite extensive literature on therapeutic strategies for cervical cancer, a bibliometric analysis specifically focused on immunotherapy for advanced, recurrent, or metastatic (A/R/M) cervical malignancies remains unexplored. This study aims to address this gap by presenting a comprehensive overview that includes general characteristics, research focal points, the trajectory of evolution, and current emerging trends in this under-researched area.
METHODS
A systematic search was conducted using the Web of Science Core Collection (WOSCC) to identify articles related to A/R/M cervical cancer published between 2000 and 2022. Citespace and VOS viewer were the primary tools used to identify research focal points, intriguing future patterns, and to evaluate contributions and co-occurrences among authors, institutions, countries, and journals.
RESULTS
A total of 1,001 original articles were identified, involving 6,387 authors from 66 countries and 1,474 institutions, and published across 366 academic journals. The United States contributed most significantly. The most productive researcher was Van der Burg SH from Leiden University Medical Center. The International Journal of Cancer and Cancer Research were identified as the most productive and influential journals, respectively. Analysis of co-citation clusters highlighted 25 clusters, primarily focusing on potential predictive biomarkers, dendritic cell-based tumor vaccines, therapeutic HPV vaccinations, peptide-based cancer vaccines, tumor immune microenvironments, and adoptive cell transfer (ACT). The latest significant trends in A/R/M cervical cancer immunotherapy research included ACT, CAR-T, and immune checkpoint inhibitors (ICIs), as revealed by keyword and reference burst detection.
CONCLUSION
This pioneering study provides a detailed landscape of immunotherapy research in A/R/M cervical cancer. It underscores the importance of global collaboration, enriches our understanding of the immunology of A/R/M cervical cancer, expands on potential beneficiaries of immunotherapy, and explores clinical applications of various therapies, including therapeutic vaccines, adoptive cell transfer, and ICIs, particularly in combination with established treatments such as chemotherapy, radiotherapy, and targeted therapy.

Review
OBJECTIVES
This systematic review aims to describe an overview of the overall care, patient and parent education, staff training, and management of complications from a nursing perspective of pediatric patients undergoing chimeric antigen receptor T (CAR-T) cell infusion in order to provide an updated summary of the approach to the management of these patients. CAR-T cellular therapy represents an innovation within pediatric hematology and oncology used to treat relapse and refractory leukemias, solid tumors, and lymphomas when standard therapy has not worked. However, this type of therapy could lead to the onset of some clinical complications that must be managed appropriately and promptly. Although their use is constantly increasing, the knowledge and resources in the literature are still limited.
DATA SOURCES
The review was conducted from January 2022 to July 2022 in PubMed, CINAHL, Scopus, and Cochrane and produced 502 articles. Based on the selection criteria and after removing duplicate articles, 26 articles were included in the study.
CONCLUSION
From these analyzed articles, it was possible to have an overview regarding the management, patient and parent education, staff training, and management of complications from a nursing perspective of pediatric patients undergoing CAR-T cell infusion.
IMPLICATIONS FOR NURSING PRACTICE
The management of hematology-oncology patients undergoing CAR-T cell therapy from a nursing perspective is not simple. We hope this review can be used as a tool to guide nursing staff. In this regard, we have developed a summary table with the actions to be taken in the case of assisting a pediatric patient being treated with CAR-T.

Review
CAR-T-cell therapy, also referred to as chimeric antigen receptor T-cell therapy, is a novel method in the field of immunotherapy for the treatment of non-Hodgkin's lymphoma (NHL). In patients receiving CAR-T-cell therapy, fluorodeoxyglucose Positron Emission Tomography/Computer Tomography ([F]FDG PET/CT) plays a critical role in tracking treatment response and evaluating the immunotherapy's overall efficacy. The aim of this study is to provide a systematic review of the literature on the studies aiming to assess and predict toxicity by means of [F]FDG PET/CT in patients with NHL receiving CAR-T-cell therapy. PubMed/MEDLINE and Cochrane Central Register of Controlled Trials (CENTRAL) databases were interrogated by two investigators to seek studies involving the use of [F]FDG PET/CT in patients with lymphoma undergoing CAR-T-cell therapy. The comprehensive computer literature search allowed 11 studies to be included. The risk of bias for the studies included in the systematic review was scored as low by using version 2 of the "Quality Assessment of Diagnostic Accuracy Studies" tool (QUADAS-2). The current literature emphasizes the role of [F]FDG PET/CT in assessing and predicting toxicity in patients with NHL receiving CAR-T-cell therapy, highlighting the evolving nature of research in CAR-T-cell therapy. Additional studies are warranted to increase the collected evidence in the literature.

The rise of immuno-oncology, including the use of chimeric antigen receptor T-cell (CAR-T) therapy is bringing in a new wave of cancer treatments, particularly in hematologic malignancies. However, data on their adverse events, particularly of the eye, is under-reported. To assess the ocular adverse events associated with the six FDA-approved CAR-T cell therapies, a disproportionality analysis utilizing the FAERS database was conducted from the first quarter of 2017 to the third quarter of 2023, as well as a systematic review of case reports of ocular events following CAR-T cell therapy up to December 20, 2023. A total of 53 ocular adverse events were identified from the FDAs FAERS database. The adverse events most frequently observed were mydriasis and xerophthalmia with tisagenlecleucel (Kymriah). The systematic review resulted in 8 case reports encompassing 19 patients which included a total of 27 events. This study demonstrates the importance of anticipation of potential ocular adverse events by ophthalmologists and oncologists as they can greatly contribute to morbidity in patients with cancer.
