    尽管转移性葡萄膜黑色素瘤(UM)的治疗有了最新进展,在许多病例中,可获得的进一步治疗方案仍然有限,预后仍然较差.除了Tebentafusp,免疫检查点阻断(ICB,PD-1(+/-)CTLA-4抗体)通常用于转移性UM,特别是在HLA-A02:01阴性患者中。然而,ICB是以潜在的严重免疫相关不良事件(irAE)为代价的。因此,选择更有可能受益于ICB的患者组是可取的.
    在此分析中,包括194例接受ICB的转移性UM患者。患者从德国皮肤癌地点和ADOReg注册表招募。为了研究irAE发生与治疗反应的关系,无进展生存期(PFS),和总生存期(OS)两个队列进行了比较:无irAE或1/2级irAE的患者(n=137)和3/4级irAE的患者(n=57)。
    在整个人口中,中位OS为16.4个月,中位PFS为2.8个月.患有3/4级irAE的患者比没有或没有1/2级irAE的患者表现出更有利的生存率(p=0.0071)。IrAE发生率为44.7%(87/194),29.4%(57/194)的患者出现严重的irAE。有趣的是,结肠炎和肝炎与较长的OS显著相关(分别为p=0.0031和p=0.011)。
    该数据可能表明irAE与接受ICB治疗的转移性UM患者的有利生存结果之间存在关联,并表明对肿瘤抗原的耐受性降低可能与对自身抗原的耐受性降低有关。
    UNASSIGNED: Despite recent advancements in the treatment of metastatic uveal melanoma (UM), the availability of further treatment options remains limited and the prognosis continues to be poor in many cases. In addition to tebentafusp, immune checkpoint blockade (ICB, PD-1 (+/-) CTLA-4 antibodies) is commonly used for metastatic UM, in particular in HLA-A 02:01-negative patients. However, ICB comes at the cost of potentially severe immune-related adverse events (irAE). Thus, the selection of patient groups that are more likely to benefit from ICB is desirable.
    UNASSIGNED: In this analysis, 194 patients with metastatic UM undergoing ICB were included. Patients were recruited from German skin cancer sites and the ADOReg registry. To investigate the association of irAE occurrence with treatment response, progression-free survival (PFS), and overall survival (OS) two cohorts were compared: patients without irAE or grade 1/2 irAE (n=137) and patients with grade 3/4 irAE (n=57).
    UNASSIGNED: In the entire population, the median OS was 16.4 months, and the median PFS was 2.8 months. Patients with grade 3/4 irAE showed more favorable survival than patients without or grade 1/2 irAE (p=0.0071). IrAE occurred in 44.7% (87/194), and severe irAE in 29.4% (57/194) of patients. Interestingly, irColitis and irHepatitis were significantly associated with longer OS (p=0.0031 and p=0.011, respectively).
    UNASSIGNED: This data may indicate an association between irAE and favorable survival outcomes in patients with metastatic UM undergoing ICB treatment and suggests that a reduced tolerance to tumor antigens could be linked to reduced tolerance to self-antigens.

    背景:肾乳头状细胞癌(KIRP)通常与受影响个体的不良预后相关。不幸的是,在寻找可靠的预后特征和预测指标来预测KIRP患者的结局方面,没有足够的探索.
    目的:本研究的目的是对鉴定预后基因的数据进行综合分析。导致具有强大预测能力的列线图的开发。目的是提供一个有价值的统计工具,当在临床环境中实施时,可以为患者提供早期治疗机会,并增加他们从这种危及生命的疾病中最终康复的机会。
    方法:使用R中的不同包装来分析来自TCGA数据门户的RNA-seq数据。多因素Cox回归分析和Kaplan-Meier分析用于研究免疫相关基因的预后价值,并构建预测模型和列线图。P值<0.05被认为是显著的。
    结果:在KIRP组织中,与正常组织相比,共有368个免疫相关基因和60个TF差异表达。在368人中,有23人与总生存率有关。GO和KEGG分析表明,这些预后免疫相关基因主要参与ERK1和ERK2级联反应,Rap1信号通路,和PI3K-Akt信号通路。从Cox回归中鉴定出9个基因是统计学上显著的预后相关基因。生存分析表明,基于这9个预后相关基因的模型具有较高的预测性能。免疫组织化学结果显示APOH,BIRC5、CCL19和GRN在肾癌中显著增高。B细胞和CD4+T细胞与风险评分模型呈正相关。
    结论:基于9个与KIRP总生存期相关的免疫相关基因,成功建立了一个预后模型。这项工作旨在为KIRP的治疗方法和预后预测因子提供一些见解。
    BACKGROUND: Kidney renal papillary cell carcinoma (KIRP) is frequently associated with an unfavorable prognosis for affected individuals. Unfortunately, there has been insufficient exploration in search for a reliable prognosis signature and predictive indicators to forecast outcomes for KIRP patients.
    OBJECTIVE: The aim of this study is to employ a comprehensive analysis of data for the identification of prognosis genes, leading to the development of a nomogram with strong predictive capabilities. The objective is to provide a valuable statistical tool that, when implemented in a clinical setting, can offer patients an early opportunity for treatment and enhance their chances of ultimate recovery from this life-threatening disease.
    METHODS: Different packages in R were used to analyze RNA-seq data from the TCGA data portal. Multivariate Cox regression analysis and Kaplan-Meier analysis were also used to investigate the prognostic values of immune-related genes and construct the predictive model and nomogram. A p-value < 0.05 was considered to be significant.
    RESULTS: A total of 368 immune-related genes and 60 TFs were identified as differentially expressed in KIRP tissues compared with normal tissues. Of the 368, 23 were found to be related to overall survival. GO and KEGG analysis suggested that these prognostic immune-related genes mainly participated in the ERK1 and ERK2 cascades, Rap1 signaling pathway, and the PI3K-Akt signaling pathway. 9 genes were identified from Cox regression to be statistically significant prognostic-related genes. Survival analysis showed that a model based on these 9 prognostic-related genes has high predictive performance. Immunohistochemistry results show that APOH, BIRC5, CCL19, and GRN were significantly increased in kidney cancer. B cells and CD4 + T cells were positively correlated with risk score model.
    CONCLUSIONS: A prognostic model was successfully created based on 9 immune-related genes correlated with overall survival in KIRP. This work aims to provide some insight into therapeutic approaches and prognostic predictors of KIRP.

    随着免疫检查点抑制剂正在扩展用于妇科恶性肿瘤,罕见的免疫相关不良事件更常见.在这里,我们描述了一位63岁的IIIB期错配修复缺陷子宫腺癌,他接受了六个周期的卡铂和紫杉醇治疗,部分反应但疾病持续存在。然后,她开始使用单一药物pembrolizumab。经过六个周期的pembrolizumab,她出现了双侧视力变化,并被诊断为后巩膜炎。Pembrolizumab被关押,她接受了口服泼尼松治疗,症状迅速缓解。泼尼松完成后一个月,再次报告了视力变化,她在更长的口服泼尼松疗程中重新开始.然后,她接受了明确的手术治疗,包括全腹腔镜子宫切除术和双侧附件卵巢切除术。最终病理为子宫内膜良性增生。她完成了类固醇课程,没有任何症状。鉴于她的完全病理反应,她随后被纳入监测,目前没有疾病证据。及时识别和治疗这种罕见的免疫相关不良事件导致预防潜在的永久性事件,使人衰弱的结果。
    As Immune checkpoint inhibitors are being expanded for use in gynecologic malignancies, rare immune-related adverse events are more frequently being reported. Here we describe a 63-year-old with Stage IIIB mismatch repair deficient uterine adenocarcinoma who underwent six cycles of carboplatin and paclitaxel with partial response but persistent disease. She was then started on single agent pembrolizumab. After six cycles of pembrolizumab, she developed bilateral vision changes and was diagnosed with posterior scleritis. Pembrolizumab was held and she was treated with oral prednisone, with rapid resolution of symptoms. One month after completion of prednisone, vision changes were again reported and she was restarted on a longer oral prednisone course. She then underwent definitive surgical management consisting of a total laparoscopic hysterectomy and bilateral salpingo-oophorectomy, with final pathology of benign endometrial hyperplasia. She has completed her steroid course without any symptoms. Given her complete pathologic response, she was subsequently placed into surveillance and is currently without evidence of disease. Prompt recognition and treatment of this rare immune-related adverse event led to the prevention of potential permanent, debilitating outcomes.

    OBJECTIVE: This study aimed to improve lung adenocarcinoma (LUAD) prognosis prediction based on a signature of immune-related long non-coding RNAs (lncRNAs).
    METHODS: LUAD samples from the TCGA database were divided into the immunity_H group and the immunity_L group. Differentially expressed RNAs (DERs) between the two groups were identified. Optimized immune-related lncRNAs combination was obtained using LASSO Cox regression. A prognostic risk prediction (RS) model was built and further validated in the training and validation datasets. A network among lncRNAs in the RS model, their co-expressed DERs, and the related KEGG pathways were established. Critical lncRNAs were validated in LUAD tissue samples.
    RESULTS: In total, 255 DERs were obtained, and 11 immune-related lncRNAs were significantly related to prognosis. Six lncRNAs were demonstrated as an optimal combination for building the RS model, including LINC00944, LINC00930, LINC00607, LINC00582, LINC00543, and LINC00319. The KM curve and ROC curve revealed the RS model to be a reliable indicator for LUAD prognosis. LINC00944 and LINC00582 showed a co-expression relationship with the MS4A1. LINC00944, LINC00582, and MS4A1 were successfully validated in LUAD samples.
    CONCLUSIONS: We have established a promising LUAD patient survival prediction model based on six immune-related lncRNAs. For LUAD patients, this prognostic model could guide personalized treatment.

    晚期黑色素瘤治疗的最新进展已导致受影响患者的生存率提高。然而,新的治疗方法也导致相当大和明显的皮肤毒性。为了进一步表征全身治疗的皮肤不良事件(AE),我们进行了一项单中心回顾性研究,研究了10年的活检证实的黑色素瘤治疗皮肤不良事件,瑞士。在102名确定的患者中,135个个体皮肤出现AE。免疫检查点阻断(ICB)是81种皮肤AE的原因,54例与靶向治疗(TT)相关。记录的皮肤AE类型包括苔藓样,斑丘疹,痤疮,荨麻疹,脂膜炎,毛囊炎,psoriasiform,肉芽肿,湿疹,和其他人。TT组(18.54%)皮肤不良事件发生率高于ICB组(9.64%,p=0.0029)。大多数AE是低等级的,尽管19.21%的AE是常见的不良事件术语标准(CTCAE)3级或4级.在晚期黑色素瘤的治疗过程中记录了大量的皮肤AE,观察到不同的表型,取决于治疗等级。TT治疗期间的AE发生时间比ICB更早,和不同类型的皮肤AE与各自的治疗类别相关。这项研究全面描述了在单个中心的黑色素瘤全身治疗期间发生的皮肤AE。
    Recent progress in the treatment of advanced melanoma has led to the improved survival of affected patients. However, novel treatments also lead to considerable and distinct skin toxicity. To further characterize cutaneous adverse events (AE) of systemic treatments, we conducted a single-center retrospective study of biopsy-proven cutaneous adverse events of melanoma treatment over a period of 10 years at the University Hospital of Zurich, Switzerland. In 102 identified patients, 135 individual skin AEs developed. Immune checkpoint blockade (ICB) was causal for 81 skin AEs, and 54 were related to targeted therapies (TT). Recorded types of skin AEs included lichenoid, maculopapular, acneiform, urticarial, panniculitis, folliculitis, psoriasiform, granulomatous, eczematous, and others. The incidence of skin AEs was higher with TT (18.54%) than with ICB (9.64%, p = 0.0029). Most AEs were low-grade, although 19.21% of AEs were common terminology criteria for adverse events (CTCAE) Grades 3 or 4. A large spectrum of skin AEs was documented during treatment of advanced melanoma, and distinct phenotypes were observed, depending on treatment classes. AEs occurred earlier during treatment with TT than with ICB, and distinct types of skin AEs were associated with respective treatment classes. This study comprehensively describes skin AEs occurring during systemic treatment for melanoma at a single center.

    背景:大约60%的自身免疫性脑炎(AE)患者表现出继发性急性症状性癫痫发作,并对免疫疗法表现出高度敏感性。然而,许多患者难以接受早期免疫治疗,因为早期识别AE的病因更为复杂.本研究旨在探讨初次免疫相关性癫痫发作的早期预测因素,并指导治疗和预后的评估。
    方法:纳入154例病程小于6个月的新发“病因不明”癫痫患者。血清和/或脑脊液神经元特异性自身抗体(NSAb),包括N-甲基-D-天冬氨酸受体(NMDAR),α-氨基-3-羟基-5-甲基-4-异恶唑丙酸受体1(AMPAR1),AMPAR2,抗富亮氨酸胶质瘤灭活1抗体(LGI1),抗γ-氨基丁酸B型受体(GABABR),使用抗接触蛋白相关蛋白2(CASPR2)筛查癫痫的免疫病因.此外,癫痫和脑病患者也通过脑MRI检查,长期视频脑电图,癫痫和脑病抗体患病率(APE2)评分,和改良的兰金量表(mRS)。采用logistic回归模型分析免疫病因的早期预测因素。
    结果:34例(22.1%)NSAb阳性。在所有154名患者中,自身免疫性脑炎(AE)23例(NSAb阳性21例),1例神经节胶质瘤(NSAb阳性),记录130例癫痫或癫痫发作(NSAb阳性12例)。此外,APE2≥4分的患者有17例(11.0%),均符合AE的临床诊断。APE2≥4点预测AE的敏感性和特异性分别为73.9%和100%。多因素分析结果显示,NSAbs和APE2评分独立影响初次免疫相关性癫痫发作的早期预测(P<0.05)。
    结论:NSAb和APE2评分可作为初始免疫相关性癫痫发作的早期预测因子。
    BACKGROUND: Approximately 60% of patients with autoimmune encephalitis (AE) exhibit secondary acute symptomatic seizures and showed highly sensitive to immunotherapy. However, it is difficult for many patients to receive early immunotherapy since the early identification of the cause in AE is more complex. This study aimed to investigate the early predictors of initial immune-related seizures and to guide the evaluation of treatment and prognosis.
    METHODS: One hundred and fifty-four patients with new-onset \"unknown etiology\" seizures with a course of disease less than 6 months were included. Serum and/or cerebrospinal fluid neuron-specific autoantibodies (NSAbs), including N-methyl-D-aspartate receptor (NMDAR), α-amino-3-hydroxy-5- Methyl-4-isoxazole propionic acid receptor 1 (AMPAR1), AMPAR2, anti-leucine rich glioma inactivated 1 antibody (LGI1), anti-gamma-aminobutyric acid type B receptor (GABABR), anti-contact protein-related protein-2 (CASPR2) were used to screen for immune etiology of the seizures. In addition, patients with epilepsy and encephalopathy were also examined via brain MRI, long-term video EEG, antibody prevalence in epilepsy and encephalopathy (APE2) score, and modified Rankin Scale (mRS). A logistic regression model was used to analyze the early predictors of immune etiology.
    RESULTS: Thirty-four cases (22.1%) were positive for NSAbs. Among all 154 patients, 23 cases of autoimmune encephalitis (AE) (21 cases of NSAbs positive), 1 case of ganglionic glioma (NSAbs positive), 130 cases of epilepsy or seizures (12 cases of NSAbs positive) were recorded. Also, there were 17 patients (11.0%) with APE2 ≥ 4 points, and all of them met the clinical diagnosis of AE. The sensitivity and specificity of APE2 ≥ 4 points for predicting AE were 73.9% and 100%. The results of multivariate analysis showed that the NSAbs and APE2 scores independently influenced the early prediction of initial immune-related seizures (P < 0.05).
    CONCLUSIONS: NSAbs and APE2 scores could act as early predictors of initial immune-related seizures.

Co-expressed genes were screened. A protein-protein interaction network was created using the STRING database. Finally, immunohistochemistry was performed to establish the expression of FCN2 in HCC tissues. A pan-cancer study centered on HCC-related molecular analysis was also conducted to look for a link between FCN2 and immune infiltration, immune modulators, and chemokine receptors.
    UNASSIGNED: In HCC tissues, the expression of FCN2 was observed to be lower than that in normal tissues. This was connected to the HCC marker alpha-fetoprotein, showing that FCN2 is involved in the development and progression of cancer. FCN2 may act through Staphylococcus aureus infection, lectins, and other pathways. Furthermore, at the immune level, the expression of FCN2 in HCC was associated with some immune cell infiltration, immunomodulators, and chemokine receptors.
    UNASSIGNED: FCN2 may be an immune checkpoint inhibitor for HCC, creating a breakthrough in the treatment of HCC.

    肝细胞癌(HCC)是全球最常见的肿瘤,也是癌症相关死亡的主要原因。HCC的高死亡率主要归因于其广泛流行和缺乏有效的治疗。作为一种有前途的免疫疗法,创新方法彻底改变了实体瘤的治疗。然而,由于肝癌的异质性和复杂的肿瘤微环境,用于免疫治疗的有效生物标志物尚未被确定.我们从癌症基因组图谱(TCGA)数据库中研究了免疫相关的长链非编码RNA(lncRNA)作为HCC患者预后生物标志物的作用。斯皮尔曼相关性,单变量和多变量Cox,和套索回归分析用于筛选与预后相关的lncRNAs。过滤出四个lncRNA以在TCGA训练以及验证队列中形成免疫相关的lncRNA预后特征。然后根据风险评分的中位数将HCC患者分为低风险组和高风险组,以评估训练和验证队列之间的预后模型的能力。建立了一个列线图(基于风险评分和阶段)来评估HCC患者的总体生存(OS)。免疫细胞浸润的差异,免疫检查点抑制剂(ICI)治疗反应,基因突变,观察两组药物敏感性。因此,lncRNA预后特征可作为一种敏感的预后生物标志物,在HCC患者的个体化免疫治疗中具有潜力.
    Hepatocellular carcinoma (HCC) is the most common neoplasm and the major cause of cancer-associated death worldwide. The high mortality rate of HCC is mainly attributed to its widespread prevalence and the lack of effective treatment. Immunotherapy as a promising, innovative approach has revolutionised the treatment of solid tumours. However, owing to the heterogeneity and complex tumour microenvironment of HCC, an efficient biomarker for immunotherapy has yet to be identified. We investigated the role of immune-related long non-coding RNAs (lncRNAs) as prognostic biomarkers in patients with HCC from The Cancer Genome Atlas (TCGA) database. Spearman correlation, univariate and multivariate Cox, and lasso regression analyses were utilised to screen lncRNAs associated with prognosis. Four lncRNAs were filtered out to develop an immune-associated lncRNA prognostic signature in TCGA training as well as validation cohorts. Patients with HCC were then categorised into low- and high-risk groups according to the median value of the risk scores to evaluate the ability of the prognostic model between training and validation cohorts. A nomogram (based on risk score and stage) was constructed to appraise the general overall survival (OS) of patients with HCC. Differences in immune cell infiltration, immune checkpoint inhibitor (ICI) treatment response, gene mutation, and drug sensitivity were observed between the two groups. Thus, the lncRNA prognostic signature can serve as a sensitive prognostic biomarker with potential in individualised immunotherapy for HCC patients.

    免疫反应是脑出血(ICH)后继发性脑损伤的重要组成部分,与神经功能缺损和预后有关。免疫反应和炎症的潜在机制对脑损伤和潜在的功能恢复具有重要意义;然而,尚未构建ICH患者外周血中的免疫相关生物标志物和竞争性内源性核糖核酸(RNA)(ceRNA)网络.我们收集了ICH患者和对照组的外周血,使用LCHumanceRNA微阵列评估他们的ceRNA谱,并用qRT-PCR验证其表达。在ICH患者的ceRNA微阵列中检测到211个DElncRNAs和100个DEmRNAs。功能富集分析结果表明,免疫应答是ICH病理过程的重要组成部分。十二个lncRNAs,十个miRNA,七个mRNA存在于我们构建的免疫相关的ceRNA网络中,结合加权基因共表达网络分析(WGCNA)。我们的研究首次建立了来自WGCNA的免疫相关的ceRNAs网络,并确定白血病抑制因子(LIF)和B细胞淋巴瘤2样13(BCL2L13)是ICH患者外周血中关键的免疫相关生物标志物,可能与PI3K-Akt相关,MAPK信号通路,和氧化磷酸化。MOXD2P-miR-211-3p-LIF和LINC00299-miR-198-BCL2L13轴参与ICH的免疫调节机制。我们研究的目的是提供对潜在免疫调节机制的创新见解,并确定ICH可能的免疫干预目标。
    The immune response is an important part of secondary brain injury following intracerebral hemorrhage (ICH), and is related to neurological deficits and prognosis. The mechanisms underlying the immune response and inflammation are of great significance for brain injury and potential functional restoration; however, the immune-related biomarkers and competing endogenous ribonucleic acid (RNA) (ceRNA) networks in the peripheral blood of ICH patients have not yet been constructed. We collected the peripheral blood from ICH patients and controls to assess their ceRNA profiles using LCHuman ceRNA microarray, and to verify their expression with qRT-PCR. Two-hundred-eleven DElncRNAs and one-hundred-one DEmRNAs were detected in the ceRNA microarray of ICH patients. The results of functional enrichment analysis showed that the immune response was an important part of the pathological process of ICH. Twelve lncRNAs, ten miRNAs, and seven mRNAs were present in our constructed immune-related ceRNA network, combining weighted gene co-expression network analysis (WGCNA). Our study was the first to establish the network of the immune-related ceRNAs derived from WGCNA, and to identify leukemia inhibitory factor (LIF) and B cell lymphoma 2-like 13 (BCL2L13) as pivotal immune-related biomarkers in the peripheral blood of ICH patients, which are likely associated with PI3K-Akt, the MAPK signaling pathway, and oxidative phosphorylation. The MOXD2P-miR-211-3p -LIF and LINC00299-miR-198-BCL2L13 axes were indicated to participate in the immune regulatory mechanism of ICH. The goal of our study was to offer innovative insights into the underlying immune regulatory mechanism and to identify possible immune intervention targets for ICH.

    透明细胞肾细胞癌(ccRCC)是最常见的泌尿系癌症之一。肿瘤微环境在肿瘤发生发展中起着重要作用。本研究旨在鉴定新型免疫相关生物标志物。使用基于GEO和TCGA数据库的ESTIMATE算法鉴定差异表达的基因。进行Kaplan-Meier存活曲线以及单变量和多变量分析。研究了ST8SIA1与免疫系统之间的关联。基因集富集分析(GSEA)和在线数据库用于功能注释。ST8SIA1被鉴定为潜在的预后基因。与邻近的正常组织相比,在肿瘤组织中观察到升高的ST8SIA1,并且与较高的T分期和晚期TNM分期有关(均p<0.05)。癌组织和细胞中ST8SIA1的mRNA和蛋白质水平也上调。Kaplan-Meier生存曲线以及单因素和多因素分析显示,ST8SIA1的高表达与OS差相关(均p<0.05)。ST8SIA1表达水平与肿瘤纯度呈负相关,与浸润免疫细胞和免疫检查点基因表达呈正相关。功能分析还显示ST8SIA1与免疫相关通路显著相关。总之,ST8SIA1被鉴定为免疫相关基因和ccRCC患者的潜在靶标。需要进一步的相关研究来验证我们的发现。
    Clear-cell renal cell carcinoma (ccRCC) is one of the most common urological cancers. The tumor microenvironment plays an important role in tumor development. The present study was conducted to identify novel immune-related biomarkers. The differentially expressed genes were identified using the ESTIMATE algorithm base on GEO and TCGA databases. The Kaplan-Meier survival curve and univariate and multivariate analyses were performed. The association between ST8SIA1 and the immune system was explored. The gene set enrichment analysis (GSEA) and online databases were used for functional annotation. ST8SIA1 was identified as a potential prognostic gene. Elevated ST8SIA1 was observed in the tumor tissues compared with adjacent normal tissues and associated with higher T stage and advanced TNM stage (all p < 0.05). The mRNA and protein levels of ST8SIA1 in cancer tissues and cells are also upregulated. The Kaplan-Meier survival curve and univariate and multivariate analyses showed that higher expression of ST8SIA1 was associated with worse OS (all p < 0.05). ST8SIA1 expression levels were negatively correlated with tumor purity and positively associated with infiltrated immune cells and expression of immune checkpoint genes. Function analysis also revealed that ST8SIA1 was significantly associated with immune-related pathways. In conclusion, ST8SIA1 was identified as an immune-related gene and a potential target in ccRCC patients. Further relevant studies are required to validate our findings.
