Gilteritinib treats acute myeloid leukemia (AML) with the FMS-like receptor tyrosine kinase-3 (FLT3) internal tandem duplication (ITD) mutation. Dysregulation of histone modification affects the genesis and progression of AML. Strategies targeting key histone regulators have not been applied to the treatment of AML. Lysine demethylase 6B (KDM6B) is dysregulated in a variety of cancers and regulates the expression of oncogenes, which has potential in anticancer therapy. We explored whether GSK-J4 (an inhibitor of the demethylase KDM6B) has an anti-leukemic effect in the gilteritinib treatment of FLT3-ITD+ AML and the effect of gilteritinib combined with GSK-J4 in leukemia. In our study, we evaluated the anti-leukemic effect of GSK-J4 in gilteritinib therapy through in vitro and in vivo experiments. The results revealed that the combined treatment of gilteritinib and GSK-J4 has greater anti-proliferation and pro-apoptosis effects than gilteritinib alone. Gilteritinib and GSK-J4 performed synergistically to arrest the cell cycle. Gilteritinib mainly induces cell cycle phase arrest at the S or G0/G1, and GSK-J4 inhibits the cell cycle progression in the S phase and reduces cell viability by reducing the expression of key regulatory factors from the G1 phase to the S phase. At the same time, GSK-J4 enhances the expression of apoptosis-related proteins (Bax and cleavage caspase-9). In addition, gilteritinib or GSK-J4 monotherapy increases reactive oxygen species (ROS) production, and the combination has a synergistic effect, accelerating leukemic cell death. Our study provides proof that the combined therapy of gilteritinib and GSK-J4 has a synergistic antileukemic effect on FLT3-ITD+ AML.
吉替尼治疗伴有fms样受体酪氨酸激酶-3 (FLT3)内部串联重复(ITD)突变的急性髓系白血病(AML)。组蛋白修饰的失调影响AML的发生和发展。针对关键组蛋白调节因子的策略尚未应用于AML的治疗。赖氨酸去甲基酶6B (Lysine demethylase 6B, KDM6B)在多种癌症中失调,并调节癌基因的表达,在抗癌治疗中具有潜力。我们探讨了GSK-J4(一种去甲基化酶KDM6B抑制剂)在吉特替尼治疗FLT3-ITD+ AML中是否具有抗白血病作用,以及吉特替尼联合GSK-J4在白血病中的作用。在我们的研究中,我们通过体外和体内实验来评估GSK-J4在吉特替尼治疗中的抗白血病作用。结果显示,吉特替尼与GSK-J4联合治疗比单独使用吉特替尼具有更强的抗增殖和促凋亡作用。Gilteritinib和GSK-J4协同阻滞细胞周期。Gilteritinib主要诱导细胞周期阻滞于S期或G0/G1期,GSK-J4通过降低G1期至S期关键调控因子的表达,抑制细胞周期进展至S期,降低细胞活力。同时GSK-J4增强凋亡相关蛋白(Bax和裂解caspase-9)的表达。此外,gilteritinib或GSK-J4单药治疗可增加活性氧(ROS)的产生,联合用药具有协同作用,加速白血病细胞死亡。我们的研究证明gilteritinib联合GSK-J4对FLT3-ITD+ AML具有协同抗白血病作用。

Colorectal cancer (CRC) ranks as the third most commonly diagnosed cancer and the second leading cause of cancer-related deaths worldwide. Studies have shown that CRC patients with KRAS mutations, especially KRASG12D, have an increased risk of metastasis. Emerging evidence indicates that long non-coding RNAs (lncRNAs) are crucial in the carcinogenesis and progression of various cancers, regulating multiple biological processes but the link between KRASG12D mutations and lncRNAs in CRC remains unclear. Therefore, this study was designed to identify a novel lncRNA involved in KRASG12D-mutated CRC and to elucidate its molecular mechanisms. The analysis of differentially expressed lncRNAs in the GSE201412 dataset revealed that LINC02159 was significantly upregulated following treatment with the KRASG12D inhibitor MTRX1133 Data from the GTEx database indicated that LINC02159 is highly expressed in CRC tumour tissues and is associated with better patient outcomes. In vitro and in vivo experiments suggest that LINC02159 acts as a tumour suppressor in CRC progression. Specifically, LINC02159 knockdown negated the inhibitory effects of MRTX1133 on tumourigenesis and its promotive effect on ferroptosis in KRASG12D-mutated CRC cells. LINC02159 expression is regulated by METTL14, with METTL14 knockdown decreasing m6A methylation of LINC02159, leading to its increased expression in CRC cells. Additionally, LINC02159 stabilised FOXC2 expression through de-ubiquitination. Rescue experiments further clarified that the METTL14/LINC02159/FOXC2 signalling axis is crucial for the inhibitory effects of MRTX1133 in KRASG12D-mutated CRC. Our study provides novel insights into the therapeutic potential of MRTX1133 in treating KRASG12D-mutated CRC by identifying a METTL14/LINC02159/FOXC2 signalling axis that mediates drug response. Our findings highlight the importance of understanding the molecular mechanisms of lncRNAs in cancer to develop effective targeted therapies.
结直肠癌(CRC)是全球第三大最常诊断的癌症,也是导致癌症相关死亡的第二大原因。研究表明,KRAS突变的结直肠癌患者,尤其是KRASG12D发生转移的风险增加。新出现的证据表明,长链非编码rna (lncRNAs)在各种癌症的发生和进展中至关重要,调节多种生物学过程,但KRASG12D突变与CRC中lncRNAs之间的联系尚不清楚。因此,本研究旨在鉴定一种参与krasg12d突变CRC的新型lncRNA,并阐明其分子机制。GSE201412数据集中差异表达的lncRNAs分析显示,在KRASG12D抑制剂MTRX1133治疗后,LINC02159的表达显著上调。来自GTEx数据库的数据表明,LINC02159在CRC肿瘤组织中高表达,并与更好的患者预后相关。体外和体内实验表明,LINC02159在结直肠癌进展中起肿瘤抑制作用。具体来说,在krasg12d突变的CRC细胞中,LINC02159的敲低否定了MRTX1133对肿瘤发生的抑制作用及其对铁下垂的促进作用。LINC02159的表达受METTL14的调控,METTL14的敲低降低了LINC02159的m6A甲基化,导致其在CRC细胞中的表达增加。此外,LINC02159通过去泛素化稳定FOXC2的表达。援救实验进一步阐明了METTL14/LINC02159/FOXC2信号轴对krasg12d突变CRC中MRTX1133的抑制作用至关重要。我们的研究通过鉴定介导药物反应的METTL14/LINC02159/FOXC2信号轴,为MRTX1133治疗krasg12d突变的CRC的治疗潜力提供了新的见解。我们的研究结果强调了了解lncrna在癌症中的分子机制对于开发有效的靶向治疗的重要性。

Background

Hepatocellular carcinoma (HCC) represents a major malignancy globally, characterized by high malignancy and intricate molecular mechanisms. This study aims to explore the role of the long non-coding RNA (lncRNA) lnc-EST885 in HCC development.

Methods

Cell experiments including FISH, western blot, flow cytometry and functional analysis were used to elucidate the effects of lnc-EST885 on cell proliferation, apoptosis, migration and EMT processes. RNA pull-down and ESI-FT-ICR-MS were used to identify proteins that interact with lnc-EST885 and were verified by RIP-qPCR. Furthermore, the association of lnc-EST885 and TRAF4 with HCC prognosis and metastasis was evaluated through bioinformatics analysis and animal models.

Results

lnc-EST885 is one of the lncRNAs with the highest expression levels in M2-type macrophages. The expression of lnc-EST885 in HCC tissues is significantly higher than in normal tissues, and high expression is associated with poor prognosis. Functional experiments have shown that lnc-EST885 significantly promotes the proliferation and migration of liver cancer cells, inhibits apoptosis, and induces EMT. Studies in a mouse lung metastasis model have also confirmed that lnc-EST885 promotes the pulmonary metastasis of HCC cells in vivo. Mechanistic studies have revealed that lnc-EST885 can bind to the TRAF4 protein, activating the PI3K/AKT signaling pathway, thereby promoting the proliferation, migration, and EMT capability of liver cancer cells, contributing to the malignant phenotype of HCC.

Conclusion

lnc-EST885 plays a crucial role in the development of liver cancer, serving as a potential biomarker for predicting HCC prognosis and providing a new target for HCC treatment.
背景:肝细胞癌(HCC)是全球性的主要恶性肿瘤,具有恶性程度高、分子机制复杂的特点。本研究旨在探讨长链非编码RNA (lncRNA) lnc-EST885在HCC发展中的作用。方法:采用FISH、western blot、流式细胞术和功能分析等细胞实验,研究lnc-EST885对细胞增殖、凋亡、迁移和EMT过程的影响。利用RNA pull-down和ESI-FT-ICR-MS鉴定与lnc-EST885相互作用的蛋白,并通过RIP-qPCR进行验证。此外,通过生物信息学分析和动物模型评估lnc-EST885和TRAF4与HCC预后和转移的相关性。结果:lnc-EST885是m2型巨噬细胞中表达水平最高的lncrna之一。lnc-EST885在HCC组织中的表达明显高于正常组织,且高表达与预后不良相关。功能实验表明,lnc-EST885能显著促进肝癌细胞的增殖和迁移,抑制细胞凋亡,诱导EMT。小鼠肺转移模型的研究也证实了lnc-EST885在体内促进HCC细胞的肺转移。机制研究表明,lnc-EST885可与TRAF4蛋白结合,激活PI3K/AKT信号通路,从而促进肝癌细胞的增殖、迁移和EMT能力,促进HCC的恶性表型。结论:lnc-EST885在肝癌的发生发展中起着至关重要的作用,可作为预测HCC预后的潜在生物标志物,为HCC治疗提供新的靶点。

Purpose The present study aimed to clarify the distribution pattern of carcinoma associated fibroblasts (CAFs) across pancreatic ductal adenocarcinoma (PDAC) and its prognostic prediction value.
Methods Data of two cohorts were retrospectively collected from consecutive patients who underwent primary pancreatic resection from January 2015 to December 2017. We used tumor specimens to screen out the most suitable markers for the spatial distribution analysis for CAFs subpopulations. We utilized a tissue microarray to assess the spatial intensity of α-SMA expression within the tumor microenvironment. Specifically, we classified CAFs into two types based on their α-SMA spatial expression. Type II CAFs were designated as those located in the juxtatumoural stroma with α-SMA expression that was moderate or higher, and those in the peripheral stroma with α-SMA expression that was less than moderate. All other cases, where the α-SMA expression did not meet these criteria, were categorized as Type I CAFs. Multivariable Cox proportional hazards regression was used to assess risk factors associated with patient outcomes. RNA sequencing data were obtained from bulk tumor samples and isolated CAFs from patients to reveal the distinct pattern and elucidated their fundamental characteristics.
Results The α-SMA spatial intensity was the most suitable variable for representative of CAFs spatial characteristics. Patients with Type Ⅰ CAFs were more likely to be allocated into N1 or N2 of the N stage and Ⅱ and Ⅲ of the TNM stage. The spatial distribution pattern of CAFs (Type Ⅰ v.s. Type Ⅱ: HR, 1.568; 95 % CI, 1.053–2.334; P = 0.027) was an independent prognostic factor in the discovery cohort, so as in the validation (Type Ⅰ vs. Type Ⅱ: HR, 2.197; 95 % CI, 1.410–3.422; P = 0.001). RNA sequencing analysis revealed that the differentially expressed genes (DEGs) in Type I CAFs are closely associated with those in corresponding tumor tissues, highlighting the enhanced biological significance of immune-related and oncogenic invasive pathways.
Conclusions Our findings that two types of α-SMA-positive CAFs with different spatial patterns present heterogeneously across tissues of PDACs and correlated with patients’ outcomes. The spatial location of CAFs may facilitate patients’ selection in precision medicine of PDACs.
目的探讨癌相关成纤维细胞(cancer associated fibroblasts, CAFs)在胰腺导管腺癌(pancreatic ductal adencarcinoma, PDAC)中的分布规律及其预后预测价值。方法回顾性收集2015年1月至2017年12月连续行原发性胰腺切除术患者的两组数据。我们使用肿瘤标本筛选出最合适的标记物用于CAFs亚群的空间分布分析。我们利用组织微阵列来评估肿瘤微环境中α-SMA表达的空间强度。具体来说,我们根据α-SMA的空间表达将CAFs分为两种类型。II型CAFs指位于瘤旁基质中α-SMA表达量中等及以上的CAFs,以及位于α-SMA表达量低于中等的周围基质中的CAFs。所有其他α-SMA表达不符合这些标准的病例被归类为I型CAFs。采用多变量Cox比例风险回归评估与患者预后相关的危险因素。从大量肿瘤样本和患者分离的CAFs中获得RNA测序数据,以揭示其独特的模式并阐明其基本特征。结果α-SMA空间强度是最适合代表CAFs空间特征的变量。Ⅰ型CAFs患者更容易被分配到N期的N1或N2和TNM期的Ⅱ和Ⅲ。CAFs的空间分布格局(Ⅰ型vs .Ⅱ型:HR, 1.568;95% ci, 1.053-2.334;P = 0.027)在发现队列中是一个独立的预后因素,在验证队列中也是如此(Ⅰ型vs.Ⅱ型:HR, 2.197;95% ci, 1.410-3.422;P = 0.001)。RNA测序分析显示,I型CAFs中的差异表达基因(DEGs)与相应肿瘤组织中的差异表达基因(DEGs)密切相关,凸显了免疫相关和致癌侵袭途径的生物学意义增强。结论两种不同空间分布的α- sma阳性CAFs在pdac组织中存在异质性,并与患者预后相关。CAFs的空间位置有助于患者在精准医疗中对其进行选择。

Background

Gastric cancer (GC) poses a major global health challenge because of its unfavorable prognosis. Elevated telomerase activity has been linked to the rapid growth and invasiveness of GC tumors. Investigating the expression profiles of telomerase could improve our understanding of the mechanisms underlying telomere-related GC advancement and its applicability as potential targets for diverse therapeutic strategies for GC.

Methods

The TCGA and GEO databases were utilized to access transcriptome and clinical data related to GC. After assessing differentially expressed genes (DEGs), a prognostic risk model was developed through Cox univariate regression, LASSO–Cox regression. The prognostic risk model was validated using data from the GSE62254 cohort. The significant influence of the risk model on the tumor immune microenvironment (TIME) and its sensitivity to various drugs was assessed.

Results

Differential expression analysis identified 328 significantly telomere-related DEGs in GC, with 35 of them showing a significant association with GC prognosis. A predictive risk model composed of four telomere-related genes (TRGs) was established, enabling the accurate stratification of GC patients into two distinct prognostic groups. The LASSO risk model demonstrated notable variations in immune-cell infiltration and drug sensitivity patterns between high- and low-risk groups.

Conclusions

The study establishes suggestive relationships between four TRGs (LRRN1, SNCG, GAMT, and PDE1B) and the prognosis of GC. The comprehensive characterization of the TRG model reveals their possible roles in the prognosis, TIME, and drug sensitivity in GC.

Immune-checkpoint inhibitors (ICIs) have revolutionized melanoma treatment, yet approximately half of patients do not respond to these therapies. Identifying prognostic biomarkers is crucial for treatment decisions. Our retrospective study assessed liquid biopsies and tumor tissue analyses for two potential biomarkers: danger-associated molecular pattern (DAMP) S100A8/A9 and its source, neutrophils. In 43 metastatic unresected stage III/IV melanoma patients, elevated serum levels of S100A8/A9 and neutrophils before and during ICI treatment correlated with worse outcomes. Furthermore, in 113 melanoma patients, neutrophil expression in the tumor microenvironment (TME) was associated with relapse and reduced survival. Measuring S100A8/A9 and neutrophils could enhance immunotherapy monitoring by predicting impaired clinical outcomes and non-response to ICIs. Serum S100A8/A9 levels and neutrophil counts at baseline (T0) and during treatment (T3) correlated with reduced progression-free survival (PFS). Elevated S100A8/A9 levels at T0 and T3 negatively impacted overall survival (OS). Notably, neutrophil infiltration was more prevalent in primary melanomas than in nevi and metastases, and its presence in primary melanomas was linked to poorer survival. S100A8/A9 serum levels, neutrophil counts, and tumor-associated neutrophil infiltration represent promising biomarkers for predicting treatment response and clinical outcomes in melanoma patients receiving ICIs.

Significance

These findings underscore the critical need for reliable biomarkers in melanoma research, particularly for predicting responses to immune-checkpoint inhibitors (ICIs). Identifying S100A8/A9 levels and neutrophil infiltration as potential indicators of treatment outcomes offers valuable insights for personalized therapy decisions. By enhancing monitoring and prognosis assessment, these biomarkers contribute to refining treatment strategies, ultimately improving patient care and outcomes. This research bridges gaps in understanding melanoma response mechanisms and highlights avenues for further investigation into immune-related markers, fostering advancements in precision medicine for melanoma patients.
免疫检查点抑制剂(ICIs)已经彻底改变了黑色素瘤的治疗,然而大约一半的患者对这些疗法没有反应。确定预后生物标志物对治疗决策至关重要。我们的回顾性研究评估了液体活检和肿瘤组织分析的两种潜在生物标志物:危险相关分子模式(DAMP) S100A8/A9及其来源中性粒细胞。在43例未切除的转移性III/IV期黑色素瘤患者中,在ICI治疗前和治疗期间血清S100A8/A9和中性粒细胞水平升高与预后较差相关。此外,在113例黑色素瘤患者中,肿瘤微环境(TME)中的中性粒细胞表达与复发和生存率降低有关。测量S100A8/A9和中性粒细胞可以通过预测临床结果受损和对ICIs无反应来加强免疫治疗监测。血清S100A8/A9水平和中性粒细胞计数在基线(T0)和治疗期间(T3)与降低的无进展生存期(PFS)相关。T0和T3时S100A8/A9水平升高对总生存期(OS)产生负面影响。值得注意的是,中性粒细胞浸润在原发性黑色素瘤中比在痣和转移瘤中更普遍,并且它在原发性黑色素瘤中的存在与较差的生存率有关。S100A8/A9血清水平、中性粒细胞计数和肿瘤相关中性粒细胞浸润是预测接受ICIs的黑色素瘤患者治疗反应和临床结果的有希望的生物标志物。意义:这些发现强调了黑色素瘤研究中可靠的生物标志物的迫切需要,特别是用于预测免疫检查点抑制剂(ICIs)的反应。确定S100A8/A9水平和中性粒细胞浸润作为治疗结果的潜在指标,为个性化治疗决策提供了有价值的见解。通过加强监测和预后评估,这些生物标志物有助于改进治疗策略,最终改善患者护理和预后。这项研究弥补了理解黑色素瘤反应机制的空白,并强调了进一步研究免疫相关标志物的途径,促进了黑色素瘤患者精准医学的进步。

It has been well established that tumor-infiltrating lymphocytes (TILs) play a critical role in the pathogenesis and progression of clear cell renal cell carcinoma (ccRCC). However, the mechanism on the interactions between TILs and tumor cells in the tumor-immune microenvironment remains unclear. In the present study, the expression of Response Gene to Complement 32 (RGC-32) was evaluated using immunohistochemistry. We analyzed the associations of RGC-32 expression with patient characteristics and survival. We also assessed TILs and their subsets (CD3+, CD4+, CD8+ and PD-1+) in the tumor nest. The level of RGC-32 expression was positively correlated with ISUP grade and Ki67 expression and was an independent poor prognosis factor of patients with ccRCC. RGC-32 expression was negatively correlated with the infiltration of TIL and CD3+T cells, but positively correlated with infiltration of PD-1+cells. In vitro studies showed that RGC-32 expression in renal cancer cells was downregulated by activated immune cells. Further investigation revealed that RGC-32 expression in renal cancer cells was inhibited by TNF-α and IL-1β secreted by activated immune cells. Collectively, these data indicate that RGC-32 could be a novel prognostic and druggable target related to the tumor-immune microenvironment in renal cancer.
肿瘤浸润淋巴细胞(til)在透明细胞肾细胞癌(ccRCC)的发病和进展中起着至关重要的作用。然而,在肿瘤免疫微环境中,TILs与肿瘤细胞相互作用的机制尚不清楚。本研究采用免疫组织化学方法检测了补体32应答基因(RGC-32)的表达。我们分析了RGC-32表达与患者特征和生存率的关系。我们还评估了肿瘤巢中的til及其亚群(CD3+、CD4+、CD8+和PD-1+)。RGC-32表达水平与ISUP分级、Ki67表达水平呈正相关,是ccRCC患者预后不良的独立因素。RGC-32表达与TIL、CD3+T细胞浸润呈负相关,与PD-1+细胞浸润呈正相关。体外研究表明,激活免疫细胞可下调RGC-32在肾癌细胞中的表达。进一步研究发现,激活免疫细胞分泌的TNF-α和IL-1β可抑制RGC-32在肾癌细胞中的表达。总之,这些数据表明RGC-32可能是肾癌中与肿瘤免疫微环境相关的一种新的预后和可药物靶点。

Background

Circular RNA (circRNA) is a new type of endogenous single-stranded RNA with a covalently closed circular structure. Increasing evidence shows that circRNA plays an important role in regulating gene expression in tumors. circICMT is a circular RNA produced by the ICMT gene. Currently, the molecular function of circICMT in bladder cancer remains unclear.

Method

Differentially expressed circRNAs were identified from RNA sequencing data and circICMT was identified as a new candidate circRNA. qRT-PCR and sanger sequencing were used to detect the expression of circICMT in bladder cancer tissue specimens. Stable cell lines overexpressing and knocking down circICMT were constructed to explore the effect of circICMT on bladder cancer cells. Its biological effects were detected through wound healing experiments, colony formation experiments, CCK-8 experiments and xenogeneic tumorigenesis experiments.

Result

This study found that circICMT was significantly upregulated in bladder cancer tissue specimens. Overexpression of circICMT can inhibit cell migration, proliferation and colony formation ability, while knockdown of circICMT promotes the malignant phenotype of bladder cancer cells. Bioinformatics predictions have found that circICMT can bind to a variety of miRNAs and RBPs and may form a complex regulatory network to regulate the progression of bladder cancer.

Conclusion

circICMT is significantly highly expressed in bladder cancer, and intervening circICMT expression affects the malignant phenotype of bladder cancer cells in vivo and in vitro, which may provide potential biomarkers and therapeutic targets for the management of bladder cancer.
背景:环状RNA (circRNA)是一种新型的内源性单链RNA,具有共价封闭的环状结构。越来越多的证据表明,circRNA在调节肿瘤基因表达中起着重要作用。circICMT是一种由ICMT基因产生的环状RNA。目前,circICMT在膀胱癌中的分子功能尚不清楚。方法:从RNA测序数据中鉴定差异表达的circRNA,并将circICMT鉴定为新的候选circRNA。采用qRT-PCR和sanger测序检测膀胱癌组织标本中circICMT的表达。构建过表达和低表达circICMT的稳定细胞系,探讨circICMT对膀胱癌细胞的作用。通过创面愈合实验、菌落形成实验、CCK-8实验和异种肿瘤发生实验检测其生物学效应。结果:本研究发现circICMT在膀胱癌组织标本中显著上调。过表达circICMT可抑制细胞迁移、增殖和集落形成能力,而敲低circICMT可促进膀胱癌细胞的恶性表型。生物信息学预测发现,circICMT可以结合多种mirna和rbp,并可能形成复杂的调控网络来调节膀胱癌的进展。结论:circICMT在膀胱癌中显著高表达,干预circICMT在体内和体外影响膀胱癌细胞的恶性表型,可能为膀胱癌的治疗提供潜在的生物标志物和治疗靶点。

Introduction

Natural killer (NK) cell activity (NKA) is downregulated in patients with colorectal cancer (CRC), and its dysfunction is possibly associated with increased risk of recurrence. However, its role in prognosis of CRC remains unclear. Prior research has shown that surgical stress can suppress NKA. This study explores the relationship between NK cell/NKA and clinicopathological factors during the perioperative period in patients with CRC.

Methods

We prospectively enrolled 45 patients with CRC. Venous blood samples were collected preoperatively and on postoperative day 3 (POD3) and 30 (POD30). NKA was assessed by measuring the plasma levels of NK cell-secreted IFN-γ.

Results

NKA was significantly reduced on POD3 compared with baseline levels before surgery but showed significant recovery by POD30. NKA on POD30 was considerably higher in patients with advanced disease stages or one or more high-risk preoperative factors. Additionally, a higher NKA recovery in patients with advanced stage exhibited improved recurrence-free survival (RFS) and progression-free survival (PFS) (hazards ratio (HR): 0.2442). Furthermore, an increased percentage of CD56bright NK cells and a higher CD56bright/CD56dim NK cell ratio postoperatively on POD30 were associated with better RFS/PFS (HR: 0.2732, P = 0.0433 and HR: 0.2193, P = 0.024, respectively).

Conclusions

Our findings indicate that a notable postoperative increase in CD56bright NK cells on POD30, both in percentage and ratio, correlates with a more favorable prognosis in CRC patients. Additionally, higher recovery rates of NKA in patients with advanced stages may offer potential applications in risk stratification and the development of treatment strategies for CRC.
导读:自然杀伤(NK)细胞活性(NKA)在结直肠癌(CRC)患者中下调,其功能障碍可能与复发风险增加有关。然而,其在结直肠癌预后中的作用尚不清楚。先前的研究表明,手术应激可以抑制NKA。本研究探讨结直肠癌患者围手术期NK细胞/NKA与临床病理因素的关系。方法:我们前瞻性地招募了45例结直肠癌患者。术前、术后第3天(POD3)和第30天(POD30)采集静脉血。通过测定血浆NK细胞分泌的IFN-γ水平来评估NKA。结果:与术前基线水平相比,NKA在POD3上显着降低,但在POD30上显着恢复。在疾病晚期或有一个或多个高危术前因素的患者中,POD30的NKA明显更高。此外,晚期患者更高的NKA恢复表现出改善的无复发生存期(RFS)和无进展生存期(PFS)(风险比(HR): 0.2442)。此外,术后POD30上CD56bright NK细胞百分比的增加和CD56bright/CD56dim NK细胞比例的增加与RFS/PFS的改善相关(HR: 0.2732, P = 0.0433和HR: 0.2193, P = 0.024)。结论:我们的研究结果表明,术后POD30上CD56bright NK细胞的显著增加,无论是百分比还是比例,都与CRC患者更有利的预后相关。此外,晚期患者更高的NKA恢复率可能为CRC的风险分层和治疗策略的制定提供潜在的应用。

Background

An increasing number of nasopharyngeal carcinoma (NPC) patients benefit from immunotherapy with chemotherapy as an induction treatment. Currently, there isn't a reliable method to assess the efficacy of this regimen, which hinders informed decision-making for follow-up care.

Aim

To establish and evaluate a model for predicting the efficacy of programmed death-1 (PD-1) inhibitor combined with GP (gemcitabine and cisplatin) induction chemotherapy based on deep learning features (DLFs) and radiomic features.

Methods

Ninety-nine patients diagnosed with advanced NPC were enrolled and randomly divided into training set and test set in a 7:3 ratio. From MRI scans, DLFs and conventional radiomic characteristics were recovered. The random forest algorithm was employed to identify the most valuable features. A prediction model was then created using these radiomic characteristics and DLFs to determine the effectiveness of PD-1 inhibitor combined with GP chemotherapy. The model's performance was assessed using Receiver Operating Characteristic (ROC) curve analysis, area under the curve (AUC), accuracy (ACC), and negative predictive value (NPV).

Results

Twenty-one prediction models were constructed. The Tf_Radiomics+Resnet101 model, which combines radiomic features and DLFs, demonstrated the best performance. The model's AUC, ACC, and NPV values in the training and test sets were 0.936 (95%CI: 0.827–1.0), 0.9, and 0.923, respectively.

Conclusion

The Tf_Radiomics+Resnet101 model, based on MRI and Resnet101 deep learning, shows a high ability to predict the clinically complete response (cCR) efficacy of PD-1 inhibitor combined with GP in advanced NPC. This model can significantly enhance the treatment management of patients with advanced NPC.
背景:越来越多的鼻咽癌(NPC)患者受益于免疫治疗和化疗作为诱导治疗。目前,尚无可靠的方法来评估该方案的疗效,这阻碍了后续护理的知情决策。目的:建立并评价基于深度学习特征(DLFs)和放射学特征预测程序性死亡-1 (PD-1)抑制剂联合GP(吉西他滨和顺铂)诱导化疗疗效的模型。方法:入选99例晚期鼻咽癌患者,按7:3的比例随机分为训练组和测试组。通过MRI扫描,DLFs和常规放射学特征恢复。采用随机森林算法识别最有价值的特征。然后利用这些放射学特征和dlf建立预测模型,以确定PD-1抑制剂联合GP化疗的有效性。采用受试者工作特征(ROC)曲线分析、曲线下面积(AUC)、准确度(ACC)和负预测值(NPV)评估模型的性能。结果:构建了21个预测模型。结合放射组学特征和DLFs的Tf_Radiomics+Resnet101模型表现出最好的性能。模型在训练集和测试集的AUC、ACC和NPV值分别为0.936 (95%CI: 0.827-1.0)、0.9和0.923。结论:基于MRI和Resnet101深度学习的Tf_Radiomics+Resnet101模型能够较好地预测PD-1抑制剂联合GP治疗晚期鼻咽癌的临床完全缓解(cCR)疗效。该模型可显著提高晚期鼻咽癌患者的治疗管理水平。
