文摘Background:Collision medullary and papillary thyroid carcinoma(MTC/PTC)is a rare entity,constituting less than 1%of all thyroid malignancies.The concurrent presence of these malignancies in patients with autoimmune thyroid disease,such as Graves’disease,is even more uncommon.Calcitonin(Ctn)is considered one of the key MTC biomarkers.Mixed tumors may alter this relationship.Case Description:We report the case of a 55-year-old female with a history of Graves’disease,who underwent total thyroidectomy for persistent dysthyroid orbitopathy.Histopathological analysis revealed a 9-mm collision MTC/PTC tumor in the left thyroid lobe,confirmed through immunohistochemical staining.Postoperative evaluation demonstrated lymph node metastases,necessitating central and left lateral neck dissection.Postoperative serum markers(calcitonin,carcinoembryonic antigen,thyroglobulin)declined significantly following surgery and radioiodine therapy.Conclusion:Subcentimeter collision MTC-PTC tumors can be aggressive,challenging size-based management thresholds.Treatment should integrate MTC and PTC protocols,with Ctn,carcinoembryonic antigen(CEA),and thyroglobulin monitored in tandem.Larger datasets are needed to refine Ctn prognostic thresholds in mixed tumors.

文摘Hepatocellular carcinoma(HCC)is a pressing global health problem and is the sixth most common cancer and the third leading cause of cancer mortality worldwide.Despite continuous advances in treatment modalities,the 5-year survival rate is low with a high propensity for recurrence and metastasis1.This clinical challenge in treating HCC is largely attributed to the heterogeneity and intrinsic therapy resistance of cancer stem cells(CSCs),which are a subpopulation of cells with self-renewal capability and multidirectional differentiation potential to induce tumorigenicity2.The behavior and maintenance of CSCs are not autonomous but critically dependent on the complex bidirectional crosstalk between CSCs and the tumor immune microenvironment(TIME)1.In this review we first summarize the recent progress in characterizing CSCs and the interactions between CSCs and the TIME in HCC.Next,we discuss the emerging therapeutic strategies targeting CSC populations with the ongoing challenges.Finally,we give our perspectives on the future directions in HCC CSC research.

文摘Oral squamous cell carcinoma(OSCC)is a prevalent malignancy with high morbidity and mortality.Globally,about 400000 people are affected,often with a poor quality of life.Its high mortality is mainly due to its aggressive growth and tendency to spread.Epithelial-mesenchymal transition(EMT)is a central regulatory hub driving tumor cell migration and invasion by enabling changes in cell characteristics.During EMT,epithelial cells gradually take on mesenchymal traits,gaining mobility and spreading mo re easily.Recent multi-omics studies show that many cancer cells exist in a hybrid or partial-EMT state,which lies between the full epithelial and mesenchymal forms.Cells in this state are especially invasive and metastatic,with high plasticity that promotes tumor progression.This review summarizes the role of partial-EMT in OSCC,with a focus on how it alters the tumor microenvironment(TME),promotes invasion and metastasis,and influences cancer stem cells(CSCs).We also highlight the link between partial-EMT and treatment resistance in OSCC.Based on these insights,we discuss therapeutic strategies targeting partial-EMT to improve outcomes.Targeting partial-EMT may offer promising strategies to enhance treatment effectiveness and improve patient survival and quality of life.

文摘Objective:The incidence and mortality of colorectal carcinoma(CRC)continue to rise globally,highlighting the need to identify modifiable risk factors for early detection and prevention.Previous studies have demonstrated significant associations between CRC risk and various serum metabolites as well as inflammatory cytokines;however,due to limitations in study design and potential confounding factors,the causal relationships remain unclear.This study aims to investigate the causal relationships between inflammatory cytokines,serum metabolites,and CRC risk,providing a theoretical basis for the development of novel early diagnostic biomarkers and therapeutic targets.Methods:A two-sample Mendelian randomization(MR)design was applied using summary statistics from genome-wide association studies(GWAS).Instrumental variables(IVs)were derived from:1)metabolomics GWAS data of 1400 serum metabolites(n=8299);2)cytokine GWAS data of 91 inflammatory factors(n=14824);and 3)CRC risk data from the FinnGen consortium(6847 cases and 314193 controls).The primary analysis was conducted using the inverse-variance weighted(IVW)method,with sensitivity analyses performed using MR Egger regression and the weighted median method.Effect estimates including odds ratios(OR),95%confidence intervals(CI),and false discovery rates(FDR)were calculated.Results:MR analysis indicated that higher levels of axin-1(AXIN1)(OR=0.84195%CI 0.714 to 0.991)and Fms-related tyrosine kinase 3 ligand(Flt3L)(OR=0.916,95%CI 0.844 to 0.994)were associated with a reduced risk of CRC.In contrast,higher levels of Delta/Notchlike epidermal growth factor-related receptor(DNER)(OR=1.119,95%CI 1.009 to 1.241)and vascular endothelial growth factor A(VEGF-A)(OR=1.078,95%CI 1.011 to 1.150)were associated with an increased risk of CRC(all P<0.05).Metabolomics association analysis further identified 144 serum metabolites significantly correlated with these four key inflammatory cytokines(FDR<0.05),suggesting that they may regulate CRC risk through inflammatory pathways.Conclusion:Specific inflammatory cytokines and serum metabolites have causal relationships with the risk of CRC.These findings provide insights for further exploration of potential risk factors and the development of effective prevention strategies for CRC.

文摘Nasopharyngeal carcinoma(NPC)is a malignant tumor prevalent in southern China and Southeast Asia,where its early detection is crucial for improving patient prognosis and reducing mortality rates.However,existing screening methods suffer from limitations in accuracy and accessibility,hindering their application in large-scale population screening.In this work,a surface-enhanced Raman spectroscopy(SERS)-based method was established to explore the profiles of different stratified components in saliva from NPC and healthy subjects after fractionation processing.The study findings indicate that all fractionated samples exhibit diseaseassociated molecular signaling differences,where small-molecule(molecular weight cut-offvalue is 10 kDa)demonstrating superior classification capabilities with sensitivity of 90.5%and speci-ficity of 75.6%,area under receiver operating characteristic(ROC)curve of 0:925±0:031.The primary objective of this study was to qualitatively explore patterns in saliva composition across groups.The proposed SERS detection strategy for fractionated saliva offers novel insights for enhancing the sensitivity and reliability of noninvasive NPC screening,laying the foundation for translational application in large-scale clinical settings.
文摘Hepatocellular carcinoma presents with three distinct immune phenotypes,including immune-desert,immune-excluded,and immune-inflamed,indicating various treatment responses and prognostic outcomes.The clinical application of multi-omics parameters is still restricted by the expensive and less accessible assays,although they accurately reflect immune status.A comprehensive evaluation framework based on“easy-to-obtain”multi-model clinical parameters is urgently required,incorporating clinical features to establish baseline patient profiles and disease staging;routine blood tests assessing systemic metabolic and functional status;immune cell subsets quantifying subcluster dynamics;imaging features delineating tumor morphology,spatial configuration,and perilesional anatomical relationships;immunohistochemical markers positioning qualitative and quantitative detection of tumor antigens from the cellular and molecular level.This integrated phenomic approach aims to improve prognostic stratification and clinical decision-making in hepatocellular carcinoma management conveniently and practically.
文摘BACKGROUND Regorafenib is approved as a second-line treatment for advanced hepatocellular carcinoma(HCC),but its comparative efficacy remains under evaluation.AIM To evaluate the efficacy and safety of regorafenib vs other second-line therapies in advanced HCC.METHODS This systematic review and meta-analysis were conducted in accordance with PRISMA guidelines.A comprehensive search of PubMed,EMBASE,Web of Science,and the Cochrane Library was performed on June 6,2025.Studies were included if they reported at least one relevant clinical outcome:Overall survival,progression-free survival,objective response rate,or disease control rate.Data was extracted independently by two reviewers.Quality was assessed using the Cochrane Risk of Bias 2.0 tool for randomized controlled trials and the Newcastle-Ottawa Scale for cohort studies.Pooled effect estimates were calculated using random-or fixed-effects models depending on the degree of heterogeneity.Sensitivity analyses and Egger’s test were performed to evaluate the robustness of the results and potential publication bias.RESULTS Nine studies met inclusion criteria.Regorafenib significantly improved overall survival compared to controls[weighted mean difference=2.54 months;95%confidence interval(CI):0.26-4.81;P<0.05],but no significant benefit was observed for progression-free survival(weighted mean difference=1.04;95%CI:-1.27 to 3.36).The pooled objective response rate showed no overall difference,though regorafenib was inferior to nivolumab in subgroup analysis(odds ratio=0.34;95% CI:0.20-0.58).Disease control rate did not differ significantly.No publication bias was detected.CONCLUSION Regorafenib offers a survival advantage in advanced HCC but does not significantly improve tumor response rates compared to alternative therapies.
文摘BACKGROUND Data comparing the outcomes of hepatocellular carcinoma(HCC)ablation by multibipolar radiofrequency ablation(mbp-RFA)and microwave ablation(MWA)are lacking.This study compares safety and efficacy of the two techniques in treatment-naive HCC.AIM To compare the risk of local tumor progression(LTP)according to the technique;secondary endpoints included technique efficacy rate at one-month,overall survival and major complication rate.METHODS A bi-institutional retrospective analysis of patients undergoing treatment-naive HCC ablation by either technique was performed.Inverse probability of treatment weighting was used to compare the two groups.Mixed effects multivariate Cox regression was applied to identify risk factors for LTP.RESULTS A total of 362 patients(mean age,66.1±6.2 years,308 men)were included,of which 242(323 tumors)treated by mbp-RFA and 120(168 tumors)by MWA.After a median follow-up of 27 months,cumulative LTP was 11.4%after mbp-RFA and 25.2%after MWA.Independent risk factors for LTP at multivariate analysis were MWA(hazard ratio=2.85,P<0.001)and tumor size(hazard ratio=1.08,P<0.001).Two-year LTP-free survival was higher after mbp-RFA than MWA regardless of size(<3 cm:96%vs 87.1%,P<0.01;≥3 cm:87.5%vs 74%,P=0.04).Technique efficacy rate was higher after mbp-RFA(94.1%vs 87.5%,P=0.01).No difference was observed in major complication rate(9.5%vs 7.5%,P=0.59),nor 5-year overall survival(63.6%vs 58.3%,P=0.33).CONCLUSION Mbp-RFA leads to better local tumor control of treatment-naïve HCC than MWA regardless of tumor size and has better primary efficacy,while maintaining a comparable safety profile.

文摘Objective:The contribution of long non-coding RNAs(lncRNAs)associated with protein palmitoylation to the progression of hepatocellular carcinoma(HCC)remains largely unclear.This study sought to establish a prognostic signature based on palmitoylation-related lncRNAs and explore their functional implications in HCC.Methods:RNA sequencing and clinical data for HCC and normal tissues were sourced from the Cancer Genome Atlas(TCGA).Pearson correlation analysis was used to identify lncRNAs that were co-expressed with palmitoylation-related genes.Univariate Cox regression was applied to select lncRNAs with prognostic value,followed by the construction of a predictive model using the least absolute shrinkage and selection operator(LASSO)regression.A focused analysis was performed on one key lncRNA,AC009403.1.Expression levels of the final nine lncRNAs included in the model were further validated by reverse transcription quantitative polymerase chain reaction(RT-qPCR).Results:A prognostic model for HCC was developed using nine palmitoylation-associated lncRNAs:AC009403.1,AC010789.1,AC026402.2,AC107021.2,AC135050.6,AL353572.4,MKLN1-AS,PRRT3-AS1,and ZNF582-AS1.This model effectively stratified patients into high-and low-risk groups exhibiting significantly different overall survival(OS)and progression-free survival(PFS),with the low-risk group showing more favorable outcomes.The high-risk group was associated with an immunosuppressive microenvironment,higher tumor mutation burden(TMB),and increased sensitivity to certain chemotherapeutic drugs(e.g.,Sorafenib).Finally,RT-qPCR validation revealed that all nine lncRNAs were significantly upregulated in HCC tissues.Conclusion:The nine-lncRNA signature exhibits robust predictive power for HCC prognosis and provides novel insights into the mechanisms of lncRNA-regulated palmitoylation in HCC development.
文摘Objective:To investigate the correlation between the expression of glucose-6-phosphate dehydrogenase(G6PD)and the clinicopathological characteristics,prognosis and immune cell infiltration of hepatocellular carcinoma(HCC).Methods:The expression of G6PD in liver cancer tissues and normal tissues is extracted from TCGA and GEO databases,validated by immunohistochemistry,and the correlation between G6PD expression and clinical features is analyzed.The clinical significance of G6PD in liver cancer is assessed by Kaplan-Meier,Cox regression,and prognostic line graph models.Functional enrichment analysis is performed by protein-protein interaction(PPI)network,GO/KEGG,GSEA and for G6PD-associated differentially expressed genes(DEGs).TIMER and ssGSEA packages are used to assess the correlation between expression and the level of immune cell infiltration.Results:Analysis of TCGA and GEO datasets revealed that G6PD expression is significantly upregulated in hepatocellular carcinoma tissues(P<0.001).G6PD expression is associated with histological grade,pathological stage,T-stage,vascular infiltration,and AFP level(P<0.05);HCC patients in the low G6PD expression group had longer overall survival and better prognosis compared with the high G6PD expression group(P<0.05).The level of G6PD expression affects the levels of macrophages,dendritic cells,B cells,and follicular helper T cells in the tumor microenvironment.Conclusion:High expression of G6PD is a potential biomarker for poor prognosis of hepatocellular carcinoma,and G6PD may be a target for immunotherapy of HCC.

文摘Atractylodes macrocephala Koidz.(A.macrocephala)is a medicinal and edible plant species belonging to the Compositae family.Its rhizome serves both therapeutic and nutritional purposes in China.This investigation led to the isolation of thirteen novel rearranged 9(8→7)-abeo-eudesmane-type sesquiterpenoid dimers(SDs),atramacronins A-M(1-13),three eudesmane-type SDs,atramacronins N-P(14-16),and two previously identified meroterpenoids,atrachinenin G(17)and atrachineninΙ(18),from Atractylodes macrocephala.Structure elucidation was accomplished through comprehensive spectroscopic analysis and single-crystal X-ray diffraction.Compounds 1,4-7,9,and 10 exhibited notable cytotoxicity against Hep3B,HepG2,and Huh7 cell lines,with half maximal inhibitory concentration(IC_(50))values ranging from 3.71 to 13.99μmol·L^(-1).
文摘This commentary critically appraises the study by Li et al which pioneered the exploration of the triglyceride-glucose(TyG)index as a prognostic marker in hepatitis B virus-related advanced hepatocellular carcinoma patients undergoing combined camrelizumab and lenvatinib therapy.While we acknowledge the study’s clinical relevance in proposing an easily accessible metabolic biomarker,we delve into the mechanistic plausibility linking insulin resistance to immunotherapy response and angiogenic inhibition.We further critically examine the methodological limitations,including the retrospective design,the populationspecific TyG cut-off value,and unaddressed metabolic confounders.We highlight the imperative for future research to validate its utility across diverse etiologies and treatment settings,and to unravel the underlying immunometabolic pathways.

文摘Background:Liver transplantation(LT)provides an option to radically eliminate hepatocellular carcinoma(HCC)on the premise that recipients are thoroughly evaluated for posttransplant tumor recurrence risk before operation.This study aimed to optimize the Milan criteria(MC)by combining circulating prognostic markers,including interleukin-6(IL-6)and alpha-fetoprotein(AFP).Methods:We retrospectively enrolled 449 HCC cases receiving LT in three medical centers in China and divided them into the training cohort(n=254)and the validation cohort(n=195).Cox regression analysis was applied to identify recurrence-related risk factors based on patients’clinical and pathological characteristics,pretransplant plasma IL-6 and AFP levels.The collaborative prediction method was presented in the form of a decision tree.Kaplan-Meier analysis showed the predictive results of independent risk factors and the newly established prediction tree.Results:In the training cohort(n=254),we established a predictive decision tree based on three independent risk factors:pretransplant plasma IL-6(>15 pg/mL),AFP(>60 ng/mL),and the MC(beyond the MC),and named it as MIA(MC-IL-6-AFP)tree.According to the MIA tree,patients beyond the MC but with IL-6≤15 pg/mL and AFP≤60 ng/mL(n=39)had comparable 3-year recurrence-free survival(RFS)rates as patients within the MC(n=121):66.8%vs.74.7%(P=0.520).Likely,in the validation cohort(n=195),the 3-year RFS rates of patients beyond the MC but with IL-6≤15 pg/mL and AFP≤60 ng/mL(n=26)were close to those of patients within the MC(n=87):71.8%vs.76.6%(P=0.660).Conclusions:We proposed that pretransplant plasma IL-6 and AFP were valid prognostic biomarkers for HCC-related LT.The MIA tree could refine the MC by combining IL-6 and AFP and define an extra subset of eligible candidates without significant sacrifice in RFS.

文摘BACKGROUND Sorafenib has been the conventional treatment for advanced hepatocellular carcinoma(HCC)since 2008.While radiological complete responses are extremely rare,improved supportive care and multidisciplinary approaches in clinical practice may explain the recent increase in case reports and retrospective series documenting such responses.CASE SUMMARY This case series describes 3 patients with advanced HCC who achieved durable complete responses using first-line sorafenib therapy,even in the presence of portal vein thrombosis or extrahepatic spread,and highlights the potential for sustained remission in selected patients.Dermatologic toxicity and non-viral etiology may correlate with favorable outcomes;however,reliable predictive biomarkers for sorafenib response are lacking.CONCLUSION Future research into the etiology and molecular differences in HCC is necessary to develop more personalized therapy options.
文摘BACKGROUND The treatment technology of liver cancer is progressing.In addition to traditional surgical resection,combined therapies of immunotherapy based on immune checkpoint inhibitors,chemotherapy,and transcatheter arterial chemoembolization for hepatocellular carcinoma are more and more widely used.Accurate preoperative diagnosis of liver cancer will provide important information for comprehensive treatment and prognosis evaluation of liver cancer.Sonazoidcontrast-enhanced ultrasound is not only helpful for the qualitative diagnosis of liver lesions,but also has great potential in the diagnosis of histological differentiation of liver cancer.AIM To assess the differentiation of hepatocellular carcinoma(HCC)by utilizing the parameters and imaging features of Sonazoid-contrast-enhanced ultrasound(CEUS).METHODS A retrospective analysis was conducted on the CEUS data of 239 lesions through case-control study.These patients received Sonazoid-CEUS within one week before surgery and were confirmed as HCC by postoperative pathology.Within the cases,patients were further categorized into well-differentiated and poorlydifferentiated group.Time-intensity curves of the region of interest in both arterial and Kupffer phases were generated,allowing for the acquisition of quantitative parameters to assess the diagnostic efficacy in distinguishing lesions between these two groups and determining an appropriate cut-off value.RESULTS Univariate analysis showed that the absolute value of enhancement intensity(EIAV),intensity ratio(IR)and intensity difference(ID)in Kupffer phase were statistically different between the groups with different degree(P=0.015,P=0.000,P=0.000).The sensitivity and specificity were 40.2%,82.4%,80.4% and 78.1%,86.9% and 74.5%,respectively,for differentiating HCC lesions with EIAV≥56.384 dB,IR≥1.215 and ID≥9.184 dB.The area under the receiver operating characteristic curve were 0.590,0.877,0.815.There was no significant difference in the parameters of arterial phase,including peak time,initial growth time,rise time and the absolute value of peak intensity of lesions between the two groups(P>0.05).Multivariate analysis showed that the level of alphafetoprotein(AFP)and IR were risk factors for poor differentiation(P=0.001).CONCLUSION Among the parameters of Sonazoid-CEUS,IR in Kupffer phase exhibits superior diagnostic efficacy with high sensitivity and specificity in the diagnose of pathological differentiation of HCC.Combined with preoperative AFP level,a more accurate diagnosis will be obtained.Compared with portal vein phase,Kupffer phase showed the ability to identify HCC lesions more sensitive.These findings hold significant guiding implications and reference value for clinical practice.

文摘Prostatic carcinoma(PCa)has become one of the most common cancers among men worldwide,with both incidence and mortality rates steadily rising.Although current treatments are effective in the early stages of PCa,many cases eventually progress to castration-resistant prostate cancer(CRPC),and led to treatment failure.To develop new therapeutic strategies to ameliorate the survival of PCa patients then has pressed the need on medicinal researchers.Of traditional Chinese medicinal herbs,Angelica gigas Naka(AGN),and its major pyranocoumarins were broadly reported on the effect of anti-PCa.However,existing reviews mainly focus on decursin(D),decursinol angelate(DA),and decursinol(DOH),without fully exploring other coumarins in AGN.Moreover,most reviews discuss general anticancer effects,with limited emphasis on PCa specifically.This review made a comprehensive summary of the coumarin components of AGN,and depicted the anti-PCa effects and mechanisms,giving a solid research support for drug discovery and development.This review also featured pharmacokinetic advantages and therapeutic potential of DOH,in order to suggest possibilities to overcome the in vivo transformation limitations of D and DA,and shed light on CRPC treatment.We also recommend future studies focus on more in vivo evidence,safety and toxicity evaluation,and clinical validation in humans.
文摘For early hepatocellular carcinoma(HCC),curative therapies include surgical excision and radiofrequency ablation.Other treatment modes for advanced HCC involve transarterial chemoembolization.For HCC patients who do not fit the Milan criteria or are waiting for liver transplantation(LT),studies of transarterial radioembolization with Yttrium-90(Y-90)demonstrated that Y-90 may accomplish a good downstaging or bridging effect before LT and can even achieve complete pathological necrosis.The present review discussed Y-90 radioembolization as a local regional treatment option for advanced and unresectable HCC,with a focus on neoadjuvant intervention before LT.
文摘Objectives:Tumor recurrence is a major determinant of poor prognosis in hepatocellular carcinoma(HCC),yet its cellular and molecular basis remains incompletely understood.This study aimed to identify recurrenceassociated genes at single-cell resolution and to develop a prognostic model for predicting survival outcomes and immunotherapy responsiveness in HCC.Methods:Single-cell RNA sequencing data from 12 primary and 6 recurrent HCC samples were integrated and analyzed to identify genes characteristic of recurrence.After quality control,principal component analysis,and t-SNE-based clustering were used to identify highly variable genes for cell clustering and annotation.Based on macrophage characteristic genes,a recurrence-related risk score was constructed using a LASSOCox regression model,and a nomogram integrating clinical variables was developed.Prognostic performance was assessed using Kaplan-Meier analysis and time-dependent ROC curves.Immune infiltration profiling was performed to compare immune characteristics between risk groups defined by the prognostic model.Multivariate Cox regression was applied to identify independent prognostic biomarkers,which were subsequently validated by cell function experiments.Results:The risk model effectively stratified patients into high-and low-risk groups with distinct survival outcomes,demonstrating high predictive accuracy for 1-,3-,and 5-year survival.High-risk patients showed altered immune profiles and a reduced predicted response to immunotherapy.GRID2,RNF186,and SLC4A10 were identified as independent prognostic genes,with RNF186 promoting HCC cell proliferation in a SESN2-dependent manner.Conclusion:This prognostic model provides new insights into precision medicine and immunotherapy for HCC,highlighting the potential clinical significance of RNF186 as a therapeutic target.
