Abstract
Chimeric antigen receptor (CAR) T-cell therapy is a relatively new and innovative immunotherapy for haemato-oncological diseases. In the UK, CAR T-cell therapy can be used to treat some patients with relapsed or refractory acute lymphoblastic leukaemia or diffuse large B-cell lymphoma. However, CAR T-cell therapy can have side effects that have implications for patients' physical and psychosocial well-being and may induce adverse reactions that can cause life-threatening acute toxicities. Nurses may have a significant role throughout the CAR T-cell therapy process, including in supporting patient decision-making, administering infusions, monitoring patients, identifying and managing adverse reactions, and providing follow-up care. This article provides an overview of CAR T-cell therapy and describes some of its potential side effects and adverse reactions. The authors also consider the role of the nurse and the implications for the nursing workforce in terms of meeting the needs of the increasing numbers of patients who may become eligible for this treatment as it is extended to other cancer types.

Liu K, Zhu Y, Li S, Zhu H. Chemoradiotherapy plus immunotherapy for locoregionally advanced nasopharyngeal carcinoma: A cost-effectiveness analysis. Head Neck 2024. [PMID: 39246032 DOI: 10.1002/hed.27932] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/21/2024] [Revised: 08/20/2024] [Accepted: 09/01/2024] [Indexed: 09/10/2024] Open
Abstract
BACKGROUND Research focused on the addition of immune checkpoint inhibitors (ICIs) to radiotherapeutic regimens in patients with cancer has become increasingly common, revealing promising improvements in efficacy outcomes. In patients with locoregionally advanced nasopharyngeal carcinoma (NPC), combining immunotherapy with chemoradiotherapy can facilitate the significant prolongation of survival, emphasizing the need for pharmacoeconomic studies focused on the clinical uptake of these innovative treatment regimens. METHODS A three-state Markov model was developed based on clinical data from the randomized phase 3 CONTINUUM trial and used to compare the cost-effectiveness of chemoradiotherapy plus sintilimab (sintilimab group) to chemoradiotherapy alone (standard group), analyzing outcomes including incremental cost-effectiveness ratio (ICER), incremental net monetary benefit (INMB), and incremental net-health benefit (INHB) values at a willingness-to-pay (WTP) threshold corresponding to three times the Chinese GDP per capita ($37 035 per quality-adjusted life year [QALY]). RESULTS The total costs for patients in the sintilimab and standard groups (QALYs [LYs]) were $92 116 (6.68 [10.03]) and $53 255 (3.75 [5.55]), respectively, for an ICER of $13 230/QALY ($8672/LY), an INMB of $70 021 with INHB of 1.89 QALYs. Using the selected WTP threshold. On the standard WTP threshold, the prevalence of sintilimab group as the primary treatment was 90.55% in China. The establishment of the model is stable. CONCLUSIONS Adding sintilimab to chemoradiotherapeutic regimens represents an innovative and cost-effective means for patients with locoregionally advanced NPC management in China.

Abstract
BACKGROUND Dendritic cell (DC) vaccines show promise for glioma treatment, but optimal use remains uncertain. This meta-analysis examined DC vaccine efficacy and safety for gliomas. METHODS This systematic review and meta-analysis study was conducted using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses. From the date of inception to October 23, 2023, electronic databases PubMed, Embase, Web of Science, and Scopus have been thoroughly evaluated. RESULTS A total of 12 studies with 998 patients and a mean age ranging from 40.2 to 56 years were included. Across 12 articles, DC vaccine 6-month overall survival (OS) was 100% [95% confidence interval {95%CI}: 100%-100%]. Respectively, 12-month OS reported 75% [95%CI: 65%-85%] but declined to 32% [95%CI: 20%-43%] for 24-month OS. 6- and 12-month progression-free survival reached 49% [95%CI: 21%-77%] and 19% [95%CI:8%-30%]. Studying radiological outcomes shows that complete response and partial response rates were 13% [95%CI: 17%-42%], and 26% [95%CI: 10%-42%], though stable disease reached 33% [95%CI: 15%-51%], suggesting predominant antineoplastic effects. The progressive disease rate also was 24% [95%CI: 9%-57%]. CONCLUSIONS In gliomas, DC vaccinations show a temporary efficacy; stability is more prevalent than regression. Impacts favor decreased resistance to early disease. Enhancing efficacy remains critical. Early therapy can be enhanced by appropriate supplementary therapy integration.

HLA-A01 and HLA-B27 Supertypes, but Not HLA Homozygocity, Correlate with Clinical Outcome among Patients with Non-Small Cell Lung Cancer Treated with Pembrolizumab in Combination with Chemotherapy. Cancers (Basel) 2024; 16:3102. [PMID: 39272960 PMCID: PMC11394546 DOI: 10.3390/cancers16173102] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/13/2024] [Revised: 09/04/2024] [Accepted: 09/04/2024] [Indexed: 09/15/2024] Open
Abstract
INTRODUCTION Maximal heterozygosity on the human leukocyte antigen (HLA) loci has been found to be associated with improved survival and development of immune-related adverse events (irAEs) among NSCLC patients treated with immunotherapy. Here, we investigated the effect of germline HLA-I/-II on clinical outcomes among NSCLC patients treated with first-line pembrolizumab in combination with chemotherapy. METHOD We prospectively recruited patients with NSCLC who were commencing first-line pembrolizumab in combination with chemotherapy. DNA from white blood cells was used for high-resolution HLA-I/II typing. RESULTS Of the 65 patients recruited, 53 complied with the inclusion criteria. We did not find an association between HLA-I/-II homozygosity and clinical outcome among the studied population. However, the presence of HLA-A01 was associated with unfavourable PFS (HR = 2.32, 95%CI 1.13-4.77, p = 0.022) and worsening OS (HR = 2.86, 95%CI 1.06-7.70, p = 0.038). The presence of HLA-B27 was associated with improved PFS (HR = 0.35, 95%CI 0.18-0.71, p = 0.004) and trends toward improving OS. None of the HLA-I supertypes were associated with the development or worsening of irAEs. CONCLUSIONS The absence of association between genomic HLA-I/-II homozygosity and clinical outcome among patients with advanced NSCLC treated with pembrolizumab in combination with chemotherapy might reflect a diminished role for HLA molecules among patients with low or no PD-L1. HLA-A01 and HLA-B27 might have a role in predicting clinical outcomes among this cohort of patients. Further studies are needed to explore biomarkers for this group of patients.

Abstract
Metastatic renal cell carcinoma (mRCC) carrying sarcomatoid features (sRCC) has aggressive biology and poor prognosis. First-line immunotherapy (IO)-based combinations have improved the outcome of clear cell RCC patients, including that of sRCC. Real-world data confirming the adequate first-line management of sRCC is largely lacking. We investigated the clinical features and the outcome of sRCC patients treated with IO-based combinations within the ARON-1 study population (NCT05287464). The primary objective was to define the incidence and baseline clinical characteristics of sRCC compared with non-sRCC patients. The secondary objective was to describe the outcome of sRCC patients based on type of first-line treatment (IO + IO vs. IO + tyrosin kinase inhibitor [TKI]). We identified 1362 mRCC patients with IMDC intermediate or poor risk, 226 sRCC and 1136 non-sRCC. These two subgroups did not differ in terms of baseline characteristics. The median overall survival (OS) was 26.8 months (95%CI 21.6-44.2) in sRCC and 35.3 months (95%CI 30.2-40.4) in non-sRCC patients (p = .013). The median progression-free survival (PFS) was longer in non-sRCC patients compared to sRCC (14.5 vs. 12.3 months, p = .064). In patients treated with first-line IO + TKI the median OS was 34.4 months compared to 26.4 months of those who received IO + IO (p = .729). The median PFS was 12.4 months with IO + TKI and 12.3 months with IO + IO (p = .606). In conclusion, we confirm that sRCC are aggressive tumors with poor prognosis. IO-based combinations improve survival outcomes of sRCC patients, regardless from the type of strategy (IO + IO versus IO + TKI) adopted.

Abstract
There is an unmet need to develop new treatments for metastatic prostate cancer. With the development of targeted radioligand therapies, bispecific T cell engagers, antibody-drug conjugates and chimeric antigen receptor T cell (CAR T) therapies, tumor-associated cell surface antigens have emerged as new therapeutic targets in metastatic prostate cancer. Ongoing and completed clinical trials targeting prostate-specific membrane antigen (PSMA), six transmembrane epithelial antigens of the prostate 1 (STEAP1), kallikrein-related peptidase 2 (KLK2), prostate stem cell antigen (PSCA), and delta-like protein 3 (DLL3) in metastatic prostate cancer were reviewed. Strategies for sequential or combinational therapy were discussed.

Abstract
BACKGROUND In the phase 2 EMPOWER-CSCC-1 study (NCT02760498), cemiplimab demonstrated antitumor activity against metastatic (mCSCC) and locally advanced cutaneous squamous cell carcinoma (laCSCC). OBJECTIVES To report final analysis of weight-based cemiplimab in mCSCC and laCSCC (Groups 1 and 2), fixed-dose cemiplimab in mCSCC (Group 3), and primary analysis of fixed-dose cemiplimab in mCSCC/laCSCC (Group 6). METHODS Patients received cemiplimab (3 mg/kg intravenously [IV] every 2 weeks [Groups 1 and 2]) or cemiplimab (350 mg IV [Groups 3 and 6]) every 3 weeks. The primary endpoint was objective response rate (ORR). Duration of response (DOR) and progression-free survival (PFS) are presented per protocol, according to post-hoc sensitivity analyses that only include the period of protocol-mandated imaging assessments. RESULTS At 42.5 months, ORR for Groups 1-3 (n=193) was 47.2%, estimated 12-month DOR was 88.3%, and median PFS was 26.0 months. At 8.7 months, ORR for Group 6 (n=165 patients) was 44.8%; median DOR and median PFS were not reached. Serious treatment-emergent adverse event rates (grade ≥3) were Groups 1-3: 31.1% and Group 6: 34.5%. LIMITATIONS Non-randomized study, non-survival primary endpoint. CONCLUSION EMPOWER-CSCC-1 provides the largest prospective data on long-term efficacy and safety for anti-programmed cell death-1 therapy in advanced CSCC.

Abstract
Background Immunotherapy has become the standard treatment for driving gene-negative advanced non-small cell lung cancer (NSCLC). However, compared to PD-L1-positive patients, the efficacy of Anti-PD-(L)1 monotherapy is suboptimal in PD-L1-negative advanced NSCLC. In this study, we aim to analyze the optimal immunotherapy approach for PD-L1-negative NSCLC patients and develop a new nomogram to enhance the clinical predictability of immunotherapy for NSCLC patients. Methods In this study, we retrieved clinical information and genomic data from cBioPortal for NSCLC patients undergoing immunotherapy. Cox regression analyses were utilized to screen the clinical information and genomic data that related to survival. The prognostic-relate genes function was studied by comprehensive bioinformatics analyses. The Kaplan-Meier plot method was employed for survival analysis. Results A total of 199 PD-L1-negative NSCLC patients were included in this study. Among them, 165 patients received Anti-PD-(L)1 monotherapy, while 34 patients received Anti-PD-(L)1+Anti-CTLA-4 combination therapy. The Anti-PD-(L)1+Anti-CTLA-4 combination therapy demonstrated significantly higher PFS compared to the Anti-PD-(L)1 monotherapy. The mutation status of KRAS, ANO1, COL14A1, LTBP1. ERBB4 and PCSK5 were found to correlate with PFS. Utilizing the clinicopathological parameters and genomic data of the patients, a novel nomogram was developed to predict the prognosis of Anti-PD-(L)1+Anti-CTLA-4 combination therapy. Conclusion Our study revealed that KRAS, ANO1, COL14A1, LTBP1. ERBB4 and PCSK5 mutation could serve as predictive biomarkers for patients with Anti-PD-(L)1+Anti-CTLA-4 combination therapy. Our systematic nomogram demonstrates significant potential in predicting the prognosis for NSCLC patients with responsive to dual PD-1/CTLA-4 blockade.

Abstract
Primary central nervous system tumors are the most frequent solid tumors in children, accounting for over 40% of all childhood brain tumor deaths, specifically high-grade gliomas. Compared with pediatric low-grade gliomas (pLGGs), pediatric high-grade gliomas (pHGGs) have an abysmal survival rate. The WHO CNS classification identifies four subtypes of pHGGs, including Grade 4 Diffuse midline glioma H3K27-altered, Grade 4 Diffuse hemispheric gliomas H3-G34-mutant, Grade 4 pediatric-type high-grade glioma H3-wildtype and IDH-wildtype, and infant-type hemispheric gliomas. In recent years, we have seen promising advancements in treatment strategies for pediatric high-grade gliomas, including immunotherapy, CAR-T cell therapy, and vaccine approaches, which are currently undergoing clinical trials. These therapies are underscored by the integration of molecular features that further stratify HGG subtypes. Herein, we will discuss the molecular features of pediatric high-grade gliomas and the evolving landscape for treating these challenging tumors.

Abstract
BACKGROUND Immunotherapy is used routinely for treating deficient mismatch repair (dMMR) colon cancer (CC). This case series highlights an emerging safety issue, where patients develop bowel obstruction associated with immunotherapy response. PATIENTS AND METHODS Patients with dMMR CC who developed bowel obstruction while responding to immunotherapy were retrospectively identified. Data on patient, disease, treatment, and response-specific factors were explored for potential risk factors. Overall treatment numbers were used to estimate incidence. RESULTS Nine patients from eight European centres were included. Common features were hepatic flexure location (5/9), T4 radiological staging (6/9), annular shape (8/9), radiological stricturing (5/9), and endoscopic obstruction (6/9). All received pembrolizumab and obstructed between 45 and 652 days after starting treatment. Seven patients underwent surgical resection; one was managed with a defunctioning stoma; and one was managed conservatively. One patient died from obstruction. Radiological response was seen in eight patients, including two complete responses. Pathological response was seen in all seven who underwent resection, including four complete responses. The overall incidence of immunotherapy response-related obstruction in these centres was 1.51%. CONCLUSIONS Bowel obstruction associated with immunotherapy response may represent a rare treatment-related complication in dMMR CC. Clinicians must recognise this safety signal and share experience to maintain patient safety.

Abstract
Renal cell carcinoma (RCC) is the most common solid tumour of the kidney and accounts for 3% of all cancers. While immune checkpoint inhibitor (ICI)-based combination therapies have emerged as the first-line treatment for metastatic renal cell carcinoma (mRCC), the role of surgery has become more controversial. This review summarizes the evidence, current role and future directions for surgery in mRCC management. The survival benefits of cytoreductive nephrectomy (CN) shown in the interferon era have encountered increasing disputes in the tyrosine-kinase inhibitor (TKI) and ICI eras. Undoubtedly, several systematic reviews based on retrospective data have supported the survival benefits of CN. Nevertheless, 2 prospective trials, CARMENA and SURTIME, proved that sunitinib as the upfront therapy resulted in noninferior survival outcomes compared with immediate CN. The safety of CN does have solid ground in the current literature. Several studies suggested that preoperative systemic therapy did not seem to aggravate perioperative complications or mortality rates, in experienced centres. Meticulous patient selection is the rule of thumb in the modern management of mRCC patients. The limitations of the existing prognostication models, however, must be acknowledged. Clinicians should adopt a multidisciplinary and holistic approach and contemplate all patient, disease, surgeon and socio-economical factors, before deciding who should go for surgery. The advent of metastasis-directed therapy (MDT) and survival benefits of adjuvant pembrolizumab shown in the oligometastatic subgroup, where complete metastasectomy could be achieved (M1 NED), calls for more comparative studies against upfront ICI combinations. In summary, CN brings survival benefits to well-selected good-to-intermediate-risk mRCC patients. Individualized and multidisciplinary care is pivotal.

Abstract
Meningiomas are the most common primary intracranial tumors in adults and typically have a slow-growing and benign nature. However, there is also a substantial subset of meningiomas that shows aggressive clinical behavior and is refractory to standard treatment modalities, which are still limited to surgery and/or radiotherapy. Despite intensive research, no systemic treatment options are yet available in the clinic for these challenging tumors, resulting in poor patient outcome. Intensive research on the molecular pathogenesis of meningiomas has led to improved diagnostic tools, but so far there is no standardized implementation for the molecular profiling of these tumors for clinical practice. Recent research advances have also focused on the immunophenotyping of meningiomas, leading to several clinical trials examining the use of immune checkpoint blockade therapy in patients with clinically aggressive subtypes. In this review, we aim to summarize the current knowledge on the molecular and immunological landscape of meningiomas in detail and provide current and progressive ideas for future directions.

Abstract
BACKGROUND Melanoma is increasingly recognized as a heterogeneous disease, with conflicting evidence regarding whether cutaneous head and neck melanoma (CHNM) represents a distinct entity. OBJECTIVE Comparison of clinicopathological features and treatment outcomes of CHNM and cutaneous melanomas of other sites (CMOS). METHODS Patients with CHNM and CMOS diagnosed between 2000-2018 were included. Locoregional control (LRC), distant metastasis-free survival (DMFS), melanoma-specific survival (MSS), and overall survival (OS) were described using the Kaplan-Meier method. Cox regression analyses were performed to examine associations between prognostic factors and outcomes. Additional analyses of survival from time of stage IV disease diagnosis were undertaken, stratified by receipt of BRAF-targeted therapy and immune checkpoint inhibitor (ICI) immunotherapy. RESULTS Of 3007 CHNM and 10637 CMOS patients, CHNM had more adverse pathological features (median age 65.9 vs. 58.5, p<0.001, median Breslow thickness 1.7mm vs. 1.2mm, p<0.001, ulceration 21.2% vs. 18.2%, p<0.001). CHNM had worse LRC (HR 1.17, p<0.001) and DMFS (HR 1.25, p<0.001) but there were no significant differences in MSS or OS. Amongst stage IV patients who received ICI, CHNM had better MSS (HR 0.56, p=0.001) and OS (HR 0.57, p<0.001) on multivariable analyses. LIMITATIONS Retrospective study, offset by prospective data collection. CONCLUSION CHNM is associated with a distinct clinicopathological and prognostic profile.

Abstract
Immune-based therapeutic interventions recognizing proteins localized on the cell surface of cancer cells are emerging as a promising cancer treatment. Antibody-based therapies and engineered T cells are now approved by the Food and Drug Administration to treat some malignancies. These therapies utilize a few cell surface proteins highly expressed on cancer cells to release the negative regulation of immune activation that limits antitumor responses (e.g., PD-1, PD-L1, CTLA4) or to redirect the T cell specificity toward blood cancer cells (e.g., CD19 and B cell maturation antigen). One limitation preventing broader application of these novel therapeutic strategies to all cancer types is the lack of suitable target antigens for all indications owing in part to the challenges in identifying such targets. Ideal target antigens are cell surface proteins highly expressed on malignant cells and absent in healthy tissues. Technological advances in mass spectrometry, enrichment protocols, and computational tools for cell surface protein isolation and annotation have recently enabled comprehensive analyses of the cancer cell surface proteome, from which novel immunotherapeutic target antigens may emerge. Here, we review the most recent progress in this field.

[PMID: 39230120 DOI: 10.1080/14796694.2024.2343272] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/12/2023] [Accepted: 04/11/2024] [Indexed: 09/05/2024] Open
Abstract
Vibostolimab, a humanized IgG1 monoclonal antibody, blocks the interaction between TIGIT and its ligands, preventing the immunosuppressive effects of TIGIT. The addition of vibostolimab to the PD-1 inhibitor pembrolizumab has shown promising antitumor activity, warranting further exploration of vibostolimab as a potential therapeutic option. The KEYVIBE program consists of nine trials that will evaluate the safety and efficacy of vibostolimab monotherapy and vibostolimab-based combination therapy in advanced solid tumors and hematological malignancies. These studies will also evaluate coformulated immunotherapy addressing issues that occur with the sequential administration of immunotherapy. The KEYVIBE program will provide further insight into the clinical utility of vibostolimab-based therapy across multiple indications and various stages of disease.

Abstract
With expansion of chimeric antigen receptor (CAR) T cell therapy and broader utilization of anti-cytokine directed therapeutics for toxicity mitigation, the routine assessment of cytokines may enhance understanding of toxicity profiles, guide therapeutic interventions, and facilitate cross-trial comparisons. As specific cytokine elevations can correlate with and provide insights into CAR T cell toxicity, mitigation strategies, and response, we explored the reporting of cytokine detection methods and assessed for the correlation of cytokines to cytokine release syndrome (CRS) and immune effector cell-associated neurotoxicity syndrome (ICANS) across clinical trials. In this analysis, we reviewed 21 clinical trials across 60 manuscripts that featured a US Food and Drug Administration-approved CAR T cell construct or one of its predecessors. We highlight substantial variability and limited reporting of cytokine measurement platforms and panels used across CAR T cell clinical trials. Specifically, across 60 publications, 28 (46.7%) did not report any cytokine data, representing 6 of 21 (28.6%) clinical trials. In the 15 trials reporting cytokine data, at least 4 different platforms were used. Furthermore, correlation of cytokines with ICANS, CRS, and CRS severity was limited. Considering the fundamental role of cytokines in CAR T cell toxicity, our manuscript supports the need to establish standardization of cytokine measurements as a key biomarker essential to improving outcomes of CAR T cell therapy.

Abstract
Background: Advancements in managing stage III melanoma have involved the implementation of adjuvant therapies alongside a simultaneous decrease in the utilization of completion lymph node dissection (CLND) following positive sentinel node biopsy (SLNB). Methods: This retrospective study from the University of Turin's Dermatology Clinic analyzed relapse-free survival (RFS) and overall survival (OS) among stage III melanoma patients (n = 157) who underwent CLND after positive SLNB versus those who did not receive such procedure. Results: Patients without CLND had a median RFS of 49 months (95% CI 42-NA), while CLND recipients showed 51 months (95% CI 31-NA) (p = 0.139). The 48-month OS for non-CLND patients was 79.8% (95% CI 58.2-91.0) versus 79.2% (95% CI 67.5-87.0) for CLND recipients (p = 0.463). Adjusted Hazard Ratios through inverse probability treatment weighting revealed the impact of CLND to be insignificant on RFS (aHR 0.90, 95% CI 0.37-2.22) and marginal on OS (aHR 0.41, 95% CI 0.13-1.21). Conversely, adjuvant therapy significantly reduced the risk of relapse (aHR 0.46, 95% CI 0.25-0.84), irrespective of CLND. Conclusions: This study corroborates the growing evidence that CLND after positive SLNB does not enhance RFS or OS, while emphasizing the crucial role of adjuvant therapy, be it immunotherapy or targeted therapy, in reducing the risk of relapse in melanoma patients with positive SLNB.

Abstract
Altered branched chain amino acids (BCAAs), including leucine, isoleucine, and valine, are frequently observed in patients with advanced cancer. We evaluated the efficacy of chimeric antigen receptor (CAR) T cell-mediated cancer cell lysis potential in the immune microenvironment of BCAA supplementation and deletion. BCAA supplementation increased cancer cell killing percentage, while accelerating BCAA catabolism and decreasing BCAA transporter decreased cancer cell lysis efficacy. We thus designed BCKDK engineering CAR T cells for the reprogramming of BCAA metabolism in the tumor microenvironment based on the genotype and phenotype modification. BCKDK overexpression (OE) in CAR-T cells significantly improved cancer cell lysis, while BCKDK knockout (KO) resulted in inferior lysis potential. In an in vivo experiment, BCKDK-OE CAR-T cell treatment significantly prolonged the survival of mice bearing NALM6-GL cancer cells, with the differentiation of central memory cells and an increasing proportion of CAR-T cells in the peripheral circulation. BCKDK-KO CAR-T cell treatment resulted in shorter survival and a decreasing percentage of CAR-T cells in the peripheral circulation. In conclusion, BCKDK-engineered CAR-T cells exert a distinct phenotype for superior anticancer efficiency.

Abstract
Cell surface proteins serve as primary drug targets and cell identity markers. Techniques such as CITE-seq (cellular indexing of transcriptomes and epitopes by sequencing) have enabled the simultaneous quantification of surface protein abundance and transcript expression within individual cells. The published data have been utilized to train machine learning models for predicting surface protein abundance solely from transcript expression. However, the small scale of proteins predicted and the poor generalization ability of these computational approaches across diverse contexts (e.g., different tissues/disease states) impede their widespread adoption. Here, we propose SPIDER (surface protein prediction using deep ensembles from single-cell RNA sequencing), a context-agnostic zero-shot deep ensemble model, which enables large-scale protein abundance prediction and generalizes better to various contexts. Comprehensive benchmarking shows that SPIDER outperforms other state-of-the-art methods. Using the predicted surface abundance of >2,500 proteins from single-cell transcriptomes, we demonstrate the broad applications of SPIDER, including cell type annotation, biomarker/target identification, and cell-cell interaction analysis in hepatocellular carcinoma and colorectal cancer. A record of this paper's transparent peer review process is included in the supplemental information.

Abstract
INTRODUCTION Although meningiomas are the most common primary brain tumor, there are limited treatment options for recurrent or aggressive lesions. Compared to other brain tumors, meningiomas may be uniquely amenable to immunotherapy by virtue of their location outside the blood-brain barrier. AREAS COVERED This review describes our current understanding of the immunology of the meninges, as well as immune cell infiltration and immune signaling in meningioma. Current literature on meningioma immunology and immunotherapy was comprehensively reviewed and summarized by a comprehensive search of MEDLINE (1/1/1990-6/1/2024). Further, we describe the current state of immunotherapeutic approaches, as well as potential future targets. Potential immunotherapeutic approaches include immune checkpoint inhibition, CAR-T approaches, tumor vaccine therapy, and immunogenic molecular markers. EXPERT OPINION Meningioma immunotherapy is in early stages, as no immunotherapies are currently included in treatment guidelines. There is substantial heterogeneity in immune cell infiltration, immunogenicity, and immune escape across tumors, even within tumor grade. Furthering our understanding of meningioma immunology and tumor classification will allow for careful selection of tumors and patient populations that may benefit from primary or adjunctive immunotherapy for meningioma.

Abstract
The last decade has seen rapid development in the field of cellular immunotherapy, particularly in regard to chimeric antigen receptor (CAR)-modified T cells. However, challenges, such as severe treatment-related toxicities and inconsistent quality of autologous products, have hindered the broader use of CAR-T cell therapy, highlighting the need to explore alternative immune cells for cancer targeting. In this regard, natural killer (NK) cells have been extensively studied in cellular immunotherapy and were found to exert cytotoxic effects without being restricted by human leukocyte antigen and have a lower risk of causing graft-versus-host disease; making them favorable for the development of readily available "off-the-shelf" products. Clinical trials utilizing unedited NK cells or reprogrammed NK cells have shown early signs of their effectiveness against tumors. However, limitations, including limited in vivo persistence and expansion potential, remained. To enhance the antitumor function of NK cells, advanced gene-editing technologies and combination approaches have been explored. In this review, we summarize current clinical trials of antitumor NK cell therapy, provide an overview of innovative strategies for reprogramming NK cells, which include improvements in persistence, cytotoxicity, trafficking and the ability to counteract the immunosuppressive tumor microenvironment, and also discuss some potential combination therapies.

Abstract
The management of advanced cutaneous squamous cell carcinoma (CSCC) has been revolutionized by the introduction of immunotherapy. Yet, successful treatment with immunotherapy relies on an adequate antitumor immune response. Patients who are solid-organ transplant recipients (SOTRs) have a higher incidence of CSCC compared to the general population. This review discusses the current knowledge of epidemiology, pathophysiology, and management of patients with CSCC who are immunocompromised because of their chronic exposure to immunosuppressive medications to prevent allograft rejection. First, we discuss the prognostic impact of immunosuppression in patients with CSCC. Next, we review the risk of CSCC development in immunosuppressed patients due to SOT. In addition, we provide an overview of the biological immune disruption present in transplanted immunosuppressed CSCC patients. We discuss the available evidence on the use of immunotherapy and provide a framework for the management approach with SOTRs with CSCC. Finally, we discuss potential novel approaches that are being investigated for the management of immunosuppressed patients with CSCC.

Abstract
Immunotherapy represents a transformative shift in cancer treatment. Among myriad immune-based approaches, chimeric antigen receptor (CAR) T-cell therapy has shown promising results in treating hematological malignancies. Despite aggressive treatment options, the prognosis for patients with malignant brain tumors remains poor. Research leveraging CAR T-cell therapy for brain tumors has surged in recent years. Pre-clinical models are crucial in evaluating the safety and efficacy of these therapies before they advance to clinical trials. However, current models recapitulate the human tumor environment to varying degrees. Novel in vitro and in vivo techniques offer the opportunity to validate CAR T-cell therapies but also have limitations. By evaluating the strengths and weaknesses of various pre-clinical glioma models, this review aims to provide a roadmap for the development and pre-clinical testing of CAR T-cell therapies for brain tumors.
