Objective: To understand distribution and drug resistance of pathogenic bacteria from a specialized cancer hospital in 2013 in order to provide a basis for rational clinical antimicrobial agents. Methods: Pathogenic bacteria identification and drug sensitivity tests were performed with a VITEK 2 compact automatic identification system and data were analyzed using WHONET5.6 software.Results: Of the 1,378 strains tested, 980 were Gram-negative bacilli, accounting for 71.1%, in which Klebsiella pneumonia, Escherichia coli and Pseudomonas aeruginosa were the dominant strains. We found 328 Gram-positive coccus, accounting for 23.8%, in which the amount of Staphylococcus aureus was the highest. We identified 46 fungi, accounting for 4.1%. According to the departmental distribution within the hospital, the surgical departments isolated the major strains, accounting for 49.7%. According to disease types, lung cancer, intestinal cancer and esophagus cancer were the top three, accounting for 20.9%, 17.3% and 14.2%, respectively. No strains were resistant to imipenem, ertapenem or vancomycin.Conclusions: Pathogenic bacteria isolated from the specialized cancer hospital have different resistance rates compared to commonly used antimicrobial agents; therefore antimicrobial agents to reduce the morbidity and mortality of infections should be used. 展开更多

AIM: To investigate adherence to medical regimen and predictors for non-adherence among children with cancer in Egypt. METHODS: We administered two study specific questionnaires to 304 parents of children diagnosed with cancer at the Children's Cancer Hospital in Cairo, Egypt, one before the first chemotherapy treatment and the other before the third. The questionnaires were translated to colloquial Egyptian Arabic, and due, to the high illiteracy level in Egypt an interviewer read thequestions in Arabic to each parent and registered the answers. Both questionnaires consisted of almost 90 questions each. In addition, a Case Report Form was filled in from the child's medical journal. The study period consisted of 7 mo(February until September 2008) and we had a participation rate of 97%. Descriptive statistics are presented and Fisher's exact test was used to check for possible differences between the adherent and non-adherent groups. A P-value below 0.05 was considered significant. Software used was SAS version 9.3 for Windows(SAS Institute Inc., Cary, NC, United States).RESULTS: Two hundred and eighty-one(90%) parents answered the second questionnaire, regarding their child's adherence behaviour. Approximately two thirds of the children admitted to their third chemotherapy treatment had received medical recommendations upon discharge from the first or second chemotherapy treatment(181/281, 64%). Sixty-eight percent(123/181) of the parents who were given medical recommendations reported that their child did not follow the recommendations. Two main predictors were found for non-adherence: child resistance(111/123, 90%) and inadequate information(100/123, 81%). In the adherent group, 20% of the parents(n = 12/58) reported trust in their child's doctor while 14 percent 8/58 reported trust in the other health-care professionals. Corresponding numbers for the non-adherent group are 8/123(7%) for both their child's doctor and other health-care professionals. Almost all of the parents expressed a lack of optimism towards the treatment(116/121, 96%), yet they reported an intention to continue with the treatment for two main reasons, for the sake of their child's life(70%)(P = 0.005) and worry that their child would die if they discontinued the treatment(81%)(P < 0.0001).CONCLUSION: Non-adherence to medical regimen is common among children diagnosed with cancer inEgypt, the main reasons being child resistance and inadequate information. 展开更多

Background: Neuroblastoma (NB) is remarkable for its wide spectrum of clinical behavior and biological characteristics in relation to outcome. The use of aggressive therapy, including autologous hematopoietic stem cell transplantation (HSCT) and the addition of isoretionin (cis-Retinoic Acid/cis-RA), has increased survival rates of patients with advanced disease. Methods: Pediatric 271 newly diagnosed high risk NB patients were prospectively enrolled into the study. Patients received neoadjuvant chemotherapy of alternating cycles: [cyclophosphamide, doxorubicin, vincristine (CAdO)] and [etoposide, carboplatin]. Intensification courses of “ICE” (ifosfamide, carboplatin, and etoposide) regimen were administered to patients with bone marrow (BM) residual infiltration. Whenever safely feasible, complete surgical resection or debulking of the primary tumor was attempted for patients achieving partial response. Eligible patients underwent HSCT, while radiation therapy to the primary and metastatic sites, as well as maintenance with cis-RA was given for 6 months. Results: The median age of our patients was 2.8 years with male to female ratio of 1.65:1. At 4 years, the overall and event free survivals were 33.7% and 23.3% for the entire group under study, with significantly higher rates (42.7% and 35.6%, respectively) for HSCT patients (n = 94;p 0.001). The outcome was also significantly correlated with response to induction therapy, pathological subtype, as well as other variables. Conclusion: Myeloablative therapy followed by stem cell rescue is regarded as the most important goal of high risk NB treatment to improve survival till present. Each of consolidation HSCT, post induction disease status, as well as international neuroblastoma pathology classification (INPC) subtype was an independent predictive variable of survival. A collaborative effort with an emphasis on biologic characteristics of aggressive disease and tailored therapy needs to be strengthened to further our understanding of this disease. 展开更多

Early stage cancers of tongue are treated traditionally with a wide local excision or hemiglossectomy, but the preservation of normal speech and swallowing are hampered. Most of the patients are treated with external beam irradiation to achieve the best locoregional control as only a limited number of tongue cancers can be excised. Underdeveloped nations with finite resources are still dependent on cobalt based external beam radiotherapy and sometimes a Linear Accelerator with two dimensional planning. This treatment has many limitations, as the large radiation fields irradiate not only the tumor but also normal tissue. The sequalae include mucositis, dry mouth, teeth and gum injury, spinal cord damage and rarely mandibular necrosis. Intensity modulated radiotherapy, which can abrogate these side effects, is not available to these patients. Irradiation using implanted solid radioactive sources into the tumor tissue is a viable option in this context. This kind of treatment is termed as brachytherapy and if the implant is introduced into the tissue then it is interstitial brachytherapy. This report details our experience in interstitial implantation, planning, dosimetry and treatment. Diagnosed cancers of anterior 2/3rd of lateral border of tongue with T1 N0M0 or T2 N0M0 stages were subjected to Iridium implantation under general anesthesia. Orthogonal films were taken and planning done with brachyvision treatment planning system. High dose rate radiotherapy was delivered as per the prescription. Excellent local control of the tumor was achieved with no undue morbidity to the adjacent structures. The patients were asked to undergo regular follow up. Surgical salvage was advised in cases of nodal recurrence. Interstitial implantation is a treatment that can be safely administered in early stage cancers of the tongue. This has remarkable efficacy and is also a patient friendly procedure. 展开更多

Nepal is a developing country with a population of around 30 million people. Cancer affects 100 - 120 people out of every 100,000, and the figure is increasing. The number of radiation facility machines in the country is still countable in fingers. Purbanchal Cancer Hospital, Nepal is the first comprehensive cancer facility capable of performing stereotactic radiosurgery (SRS). Our facility has cutting-edge Varian Truebeam Linear Accelerators with millennium MLC, which makes SRS and SRT’S for intracranial lesions such as small benign and malignant tumors much easier. In addition to SRS, we are the pioneers of SBRT for lung using 4DCT, interstitial & intraluminal brachytherapy, RPM Gated & DIBH modalities in Nepal. Methods & Materials: The purpose of this study is to share our experience in establishing an SRS facility in the country, which includes training the RT team on the importance of process accuracy, patient selection, patient assessment, mould preparation, and describing image data acquisition, target, and organ at risk delineation on CT and MRI images, treatment planning process, and quality assurance. Results & Discussion: The plans for all SRS and SRT cases are based on target coverage, OAR sparing, hotspot inside the target, conformity index, heterogeneity index, and dose fall off. To select the final plan, we used strict passing criteria such as a conformity index Paddick (CIPaddick) more than 0.85, a falloff between 100% and 50% of less than 5.5 mm (maximum 6 mm in irregular targets), and a hotspot inside the target between 115 to 140 percent, as per clinical standards. In addition, we determined the CILomax and CIRTOG for each case. Passing criteria for verification plans are set as minimum of 95% for a 2% percentage dose difference (% DD) and a 2-mm distance to an agreement (DTA). We also gathered demographic data from patients treated in the first year, such as diagnosis, lesion size, dose fraction, heterogeneity index (HI), conformity index (CI) and gamma index. SRS/SRT treatment was successfully implemented, and over 40 patients were treated with positive clinical outcomes. Conclusion: SRS now has a wider range of alternatives, thanks to technology advancements in recent years. SRS’s dosimetric advantages have steadily been extended to extracranial locations. Purbanchal Cancer Hospital, Birtamode, Nepal established a comprehensive cancer facility with qualified workforce with the goal of providing high-quality treatment to the people of Nepal. 展开更多

Objective:To determine whether immunotherapy can bring new hope for patients with limited-stage small-cell lung cancer(LS-SCLC).We conducted this retrospective study to evaluate whether immunotherapy can achieve better efficacy in LS-SCLC patients.Methods:We evaluated 122 LS-SCLC patients who received concurrent chemoradiotherapy(CCRT)or sequential chemoradiotherapy(SCRT)(Group A)and immunotherapy combined with CCRT/SCRT followed by immunotherapy(Group B),to assess the objective response rate(ORR),disease control rate(DCR),and progression-free survival(PFS).Factors affecting prognosis were also explored using Cox analysis.The prognosis of patients with type 2 diabetes and patients with different TNM stages was compared to guide the selection of clinical regimens.Results:The overall ORR was 55.93%.The overall DCR was 98.31%.The DCR was 100%in Group A and 96.61%in Group B.There was no statistical difference in ORR and DCR.The overall median PFS was 9.86 months(95%CI,8.62-11.10),and the difference in median PFS between the two groups was statistically significant(8.94 vs.11.89 months,p=0.03).The Cox regression analysis showed type 2 diabetes was associated with the survival prognosis.Patients with type 2 diabetes tended to choose immunotherapy combined with CCRT/SCRT.Patients in TNM stage IIIB had a significantly worse prognosis than those in stage I+II+IIIA.Conclusion:We suggest that LS-SCLC patients who receive immunotherapy combined with CCRT/SCRT can achieve longer PFS than those with CCRT/SCRT.Type 2 diabetes and TNM stage affect the survival prognosis.Patients with type 2 diabetes may benefit from immunotherapy combination treatments. 展开更多

It remains a major challenge in phototherapeutics to achieve a high quantum yield of singlet oxygen generation and efficient photothermal conversion using a single near-infrared laser for immuno-phototherapy.To bridge this gap,we utilized an acceptor-donor-acceptor(A-DA)structured molecule,3,9-bis(2-methylene-((3-(1,1-dicyanomethylene)-6/7-methyl)-indanone))-5,5,11,11-tetrakis(4-hexylphenyl)-dithieno[2,3-d:2′,3′-d′]-s-indaceno[1,2-b:5,6-b′]-dithiophene(m-ITIC),and formulated it into nanoparticles(NPs)by assembling with distearoylphosphatidylethanolamine-polyethylene glycol-amino(DSPE-PEG-NH_(2)).At 688 and 768 nm,these NPs present significant near-infrared absorption and fluorescence.They simultaneously generate heat,O_(2)^(-•),and 1O_(2),with the^(1)O_(2)generation quantum yield of 56.8%and photothermal conversion efficiency(PCE)of 27.4%,enabling them excellent near-infrared(NIR)fluorescence imaging guided synergic photodynamic therapy(PDT)and photothermal therapy(PTT)capabilities.Importantly,this nanoplatform induces PANoptosis,a coordinated cell death program integrating pyroptosis,apoptosis,and necroptosis,in tumor cells,thereby amplifying immunogenic cell death(ICD)and enhancing antitumor immune responses.The combined effects lead to robust dendritic cell activation,macrophage polarization toward the M1 phenotype,elevated CD8^(+)T cell infiltration,and suppression of immunosuppressive Treg cells,resulting in significant tumor growth inhibition and prevention of lung metastasis in vivo.Furthermore,the therapeutic efficacy was validated in patient-derived tumor organoids,demonstrating translational potential.This study presents a novel strategy for NIR light-guided cancer phototherapy,wherein a single laser-activated nanoplatform simultaneously mediates efficient photothermal and photodynamic effects and induces PANoptosis driven ICD for synergistic cancer immunotherapy. 展开更多

BACKGROUND Gastric cancer(GC)is one of the most common malignant tumors of the digestive system worldwide,the prognosis of patients with advanced GC remains poor.AIM To evaluate the combined expression characteristics of cancer stem cell markers CD24 and CD133 in GC pathological tissues,and to explore their association with patients’clinicopathological parameters and postoperative survival outcomes.METHODS A total of 304 GC patients who underwent surgical treatment in our hospital from January 2018 to January 2020 were retrospectively included.Immunohistochemistry was used to detect the protein expression of CD24 and CD133 in tumor tissues,adjacent tissues,and normal gastric mucosa tissues.Based on staining intensity and the proportion of positive cells,expression levels were classified into low and high expression,while clinicopathological parameters were recorded.χ2 test was used to evaluate the correlation between expression and categorical variables,Spearman rank correlation analysis was performed to assess the correlation between the expression intensities of the two markers,and multivariate regression models were applied to identify independent risk factors influencing co-expression.Kaplan-Meier survival curves and Log-rank test were used to compare survival differences among groups with different expression patterns.RESULTS Among the 304 patients,155 cases(50.99%)were CD24 positive,including 91 low-expression and 64 highexpression;133 cases(43.75%)were CD133 positive,including 81 low-expression and 52 high-expression.There were 74 cases(24.34%)with double positivity and 81 cases(26.64%)with double negativity.Compared with tumor tissues,the positive rates of CD24 and CD133 in normal gastric tissues and adjacent tissues were significantly lower(P<0.05).Univariate analysis showed that co-expression of CD24 and CD133 in GC tissues was significantly correlated with tumor size,Lauren classification,T stage,N stage,and vascular invasion(P<0.05),but not with patient age,gender,tumor site,World Health Organization histological classification,or M stage(P>0.05).Further multivariate regression analysis suggested that tumor size,T stage,N stage,and vascular invasion were independent risk factors promoting CD24 and CD133 double positivity.Spearman rank correlation analysis indicated a moderate positive correlation between their expression intensities(r=0.420,P<0.001).During follow-up,29 of 304 patients were lost(loss rate 9.54%);146 deaths occurred.According to expression combination,there were 89 cases of CD24 single positivity(39 deaths),68 cases of CD133 single positivity(31 deaths),81 cases of double negativity(25 deaths),and 66 cases of double positivity(51 deaths).Log-rank test showed significant differences in overall survival among the four groups(χ2=20.89,P<0.001),with CD24+/CD133+group showing the worst prognosis.CONCLUSION CD24 and CD133 exhibit high positive detection rates in GC tissues,and their co-positivity is closely associated with tumor stage progression and significantly indicates unfavorable survival outcomes.The co-expression of CD24/CD133 may reflect higher aggressiveness and metastatic potential of GC,serving as a potential prognostic marker and a direction for targeted therapeutic strategies.However,as this is a single-center retrospective study with limitations such as patient loss to follow-up and sample size,further prospective,multicenter,and mechanistic studies are required to validate its clinical applicability and biological role. 展开更多

In recent years the crucial role of CD4^(+)T cells in tumor immunomodulation has garnered increasing recognition.While conventional cancer immunotherapy research has predominantly focused on the cytotoxic function of CD8+T cells,emerging evidence has now shown that CD4^(+)T cells enhance antitumor immunity by delivering co-stimulatory signals,secreting cytokines,and promoting cytotoxic T lymphocyte(CTL)activation and display unique immunoregulatory capabilities through direct tumor cell killing or remodeling of the tumor microenvironment.The high heterogeneity and functional plasticity of CD4^(+)T cell subsets significantly influence clinical responses to immunotherapy with underlying mechanisms involving multi-level regulatory networks,including epigenetic modulation and metabolic reprogramming.Deciphering the functional heterogeneity of CD4^(+)T cells and the interactions with the tumor microenvironment will provide essential mechanistic insights for next-generation immunotherapies,such as immune checkpoint inhibitors and chimeric antigen receptor T(CAR-T)therapies,thereby advancing personalized treatment paradigms. 展开更多

Background:Receptor-interacting protein kinases(RIPKs)regulate cell death,inflammation,and immune responses,yet their roles in cancer are not fully understood.This study investigates the expression,genomic alterations,and functional implications of RIPK family members across various cancers.Methods:We collected multi-omics data from The Cancer Genome Atlas and other public databases,including gene expression,copy number variation(CNV),mutation,methylation,tumor mutation burden(TMB),and microsatellite instability(MSI).Differential expression and survival analyses were performed using DESeq2 and Cox proportional hazards models.CNV and mutation data were analyzed with GISTIC2 and Mutect2,and methylation data with the ChAMP package.Correlations with TMB and MSI were assessed using Pearson coefficients,and gene set enrichment analysis was conducted with the MSigDB Hallmark gene sets.Results:RIPK family members show significant differential expression in various cancers,with RIPK1 and RIPK4 frequently altered.Survival analysis reveals heterogeneous impacts on overall survival.CNV and mutation analyses identify high alteration frequencies for RIPK2 and RIPK7,affecting gene expression.RIPK1 and RIPK7 are hypermethylated in several cancers,inversely correlating with RIPK3 expression.RIPK1,RIPK2,RIPK5,RIPK6,and RIPK7 correlate positively with TMB,while RIPK3 shows negative correlations in some cancers.MSI analysis indicates associations with DNA mismatch repair.G ene set enrichment analysis highlights immune-related pathway enrichment for RIPK1,RIPK2,RIPK3,and RIPK6,and cell proliferation and DNA repair pathways for RIPK4 and RIPK5.RIPK family members showed heterogeneous alterations across cancers:for example,RIPK7 was mutated in up to~15%of u terine c orpus e ndometrial c arcinoma and l ung s quamous c ell c arcinoma cases,and RIPK1 and RIPK7 exhibited frequent promoter hypermethylation in multiple tumor types.Several genes displayed context-dependent associations with overall survival and with TMB/MSI.Conclusion:This pan-cancer analysis of the RIPK family reveals their diverse roles and potential as biomarkers and therapeutic targets.The findings emphasize the importance of RIPK genes in tumorigenesis and suggest context-dependent functions across cancer types.Further studies are needed to explore their mechanisms in cancer development and clinical applications. 展开更多

Neoadjuvant therapy(NAT)has become the standard treatment for patients with locally advanced breast cancer and stage II-III HER2-positive(HER2+)or triple-negative breast cancer(TNBC)1,2.It is essential to accurately mark the primary breast tumor and positive axillary lymph nodes(ALNs)prior to NAT to ensure precise surgical excision,guide axillary downstaging,and guarantee reliable lesion retrieval for pathologic evaluation3.The false-negative rate of sentinel lymph node biopsy(SLNB)after NAT can be reduced to<10%by applying modalities,such as the identification of≥3 sentinel lymph nodes(SLNs)with dual-mapping techniques or removal of the marked lymph node with target axillary dissection(TAD)according to the ASCO,NCCN,and CBCS guidelines3-5.However,there is a lack of consensus regarding the optimal methods and materials for accurate marking6,7.Conventional techniques include clip placement,guidewire localization,and carbon or ink tattooing,whereas wireless technologies,such as MagseedR,radiofrequency identification tags,SAVI SCOUTR,and radioactive iodine-125(125I)seeds,have also been adopted.Traditional marking techniques have a localization failure rate of approximately 10%.In contrast,the use of 125I seeds(with a radiation dose of 0.1-0.3 mCi)has significantly improved localization accuracy8,9.Nevertheless,owing to radioactive properties,concerns have been raised regarding the potential impact of 125I seed marking on assessing the pathologic complete response(pCR)after NAT10.Moreover,whether the influence of 125I seed marking on pCR could lead to suboptimal adjuvant treatment decisions and potentially compromise long-term oncologic outcomes has not been established.To investigate the potential impact of 125I seed placement on the pCR rate and long-term outcomes in breast cancer patients receiving NAT,we conducted a retrospective cohort study utilizing propensity score matching(PSM). 展开更多

Background:Gastric cancer(GC)remains highly lethal,with metabolic reprogramming as a key hallmark.This study explores Centromere Protein F(CENPF)’s role in GC pathogenesis,specifically its regulation of glutamine metabolism.Methods:The Cancer Genome Atlas-Stomach Adenocarcinoma(TCGA-STAD),GSE19826,and GSE27342 datasets were analyzed by bioinformatics to identify key candidate genes in GC.The function of CENPF was assessed by flow cytometry,colony formation assays,and Cell Counting Kit-8(CCK-8).RNA sequencing,metabolic profiling,chromatin immunoprecipitation(ChIP),western blot(WB),and luciferase reporter assay were employed to investigate the fundamental mechanisms.Results:CENPF was upregulated in GC tumor samples and had a high diagnostic potential.CENPF knockdown declined cell proliferation,caused G2 arrest,and promoted apoptosis in GC cells.RNA sequencing revealed that CENPF was involved in glutamine metabolism.CENPF overexpression enhanced glutamine consumption and glutamate production,while glutamine deficiency reversed CENPF-mediated cell survival.CENPF stabilized cellular myelocytomatosis(c-Myc)by preventing proteasomal degradation,bound to the glutaminase(GLS)promoter,promoting glutamine metabolism.Overexpression of GLS or c-Myc rescued the CENPF knockdown’s inhibitory effect on GC cell growth.Conclusion:Our findings identify a new CENPF/c-Myc/GLS axis that affects glutamine metabolism and cell survival in GC,implying that CENPF might be a novel target for the treatment of GC. 展开更多

BACKGROUND The liver represents a common site of distant metastasis in patients with esophageal cancer(EC).Conventional chemotherapy(CMT)presents limited efficacy for EC,and EC patients with liver metastases typically experience a poor prognosis,highlighting an urgent need to explore novel treatment approaches.This study evaluated the overall efficacy and safety of CMT vs CMT combined with immune checkpoint inhibitors(ICIs)in the treatment of EC patients with liver metastases.Furthermore,prognostic factors influencing outcomes in this patient population were identified.AIM To evaluate the efficacy and safety of first-line chemoimmunotherapy for EC patients with liver metastases and to analyze prognostic factors.METHODS This retrospective study included 126 EC patients with liver metastases at Zhejiang Cancer Hospital between 2014 and 2024.Patients receiving CMT were compared with those receiving CMT+ICI.Analyzed variables included clinicopathological features,treatment history,characteristics of metastasis,systemic and local treatments,overall survival(OS),and treatment-related adverse events(TRAEs).Prognostic factors were evaluated using univariate and multivariate Cox proportional-hazards regression models.Finally,efficacy outcomes and TRAE profiles were compared between the two groups.RESULTS A significant difference in median OS was identified between the two groups(10.8 months in the CMT group vs 20.8 months in the CMT+ICI group,P=0.004).The CMT+ICI group also demonstrated a significantly longer median progression-free survival of 11.7 months(P<0.001).Patients receiving combination therapy exhibited significantly improved systemic objective response rate and disease control rate.Multivariate analysis identified key factors significantly influencing OS in EC patients with liver metastases:Karnofsky Performance Status score≥70,receipt of local therapy for liver metastases,and the number of cycles of CMT and immunotherapy received.Furthermore,the incidence of TRAEs did not significantly differ between the CMT+ICI and CMT groups.CONCLUSION For EC patients with liver metastases,the combination of CMT and ICIs demonstrates significantly superior efficacy compared with CMT alone,while maintaining manageable TRAEs. 展开更多

Triple-negative breast cancer(TNBC)presents significant diagnostic and therapeutic challenges due to the lack of targeted treatments,rapid progression,high recurrence and metastasis rates,and overall poorer prognosis.Herein,the targeted theranostic platform of cysteine-modified gold nanodots-sulfhydrated luteinizing hormone releasing hormone(CGN-SLR)nanosystem was designed for target recognition and precise dual-mode imaging-guided photothermal therapy(PTT)against TNBC.On the one hand,the CGN-SLR nanosystem can serve as an ideal targeting fluorescent probe and computed tomography(CT)enhancer to facilitate the accurate diagnosis and surgical guidance of TNBC.On the other hand,the CGN-SLR nanosystem with great targeting and PTT ability can significantly inhibit the growth of TNBC,without causing harm to normal tissues and healthy organs.It provides an effective strategy for the diagnosis and treatment of TNBC through the rational design of multifunctional nanoplatform with target recognition,multiple imaging guidance/monitoring,and high-efficiency PTT. 展开更多

Conventional treatments for non-small cell lung cancer(NSCLC)suffer from low remission rates,high drug resistance,and severe adverse effects.To leverage the therapeutic potential of reactive oxygen species(ROS),nanocatalytic medicine utilizes nanomaterials to generate ROS specifically within tumor sites,enabling efficient and targeted cancer treatment.In this study,hyaluronic acid(HA)-modified copper-N,N-dimethyl-Nphenylsulfonylbisamine(DMSA)-assembled nanoparticles(Cu-DMSA-HA NPs)are developed with tumor-targeting capability and efficiently catalyze ROS production via coordination chemistry.Targeted delivery is facilitated by HA surface modification through recognition of overexpressed cluster of differentiation 44 receptors on cancer cells,which enhances nanoparticle uptake.Once internalized,intracellular glutathione is depleted by the NPs,followed by a Fenton-like reaction that sustains ROS production.Both in vitro and in vivo studies demonstrate that this catalytic strategy effectively inhibits DNA replication,prevents cell cycle progression,downregulates glutathione peroxidase 4 expression,induces ferroptosis,and ultimately suppresses NSCLC progression.Overall,the readily prepared Cu-DMSA-HA NPs exhibit robust catalytic activity and tumor specificity,highlighting their strong potential for clinical translation in nanocatalytic cancer therapy. 展开更多

Prostate cancer(PCa)remains a major cause of cancer-related mortality in men,largely due to therapy resistance and metastatic progression.Increasing evidence highlights the tumor microenvironment(TME),particularly cancer-associated fibroblasts(CAFs),as a critical determinant of disease behavior.CAFs constitute a heterogeneous population originating from fibroblasts,mesenchymal stem cells,endothelial cells,epithelial cells undergoing epithelial-mesenchymal transition(EMT),and adipose tissue.Through dynamic crosstalk with tumor,immune,endothelial,and adipocyte compartments,CAFs orchestrate oncogenic processes including tumor proliferation,invasion,immune evasion,extracellular matrix remodeling,angiogenesis,and metabolic reprogramming.This review comprehensively summarizes the cellular origins,phenotypic and functional heterogeneity,and spatial distribution of CAFs within the prostate TME.We further elucidate the molecular mechanisms by which CAFs regulate PCa progression and therapeutic resistance,and critically evaluate emerging strategies to therapeutically target CAFmediated signaling,metabolic,and immune pathways.By integrating recent advances from single-cell and spatial transcriptomics(ST),our objective is to provide a holistic framework for understanding CAF biology and to highlight potential avenues for stromal reprogramming as an adjunct to current PCa therapies. 展开更多

Background: The increasing prevalence of colorectal cancer(CRC) in China and the paucity of information about relevant expenditure highlight the necessity of better understanding the financial burden and effect of CRC diagnosis and treatment. We performed a survey to quantify the direct medical and non-medical expenditure as well as the resulting financial burden of CRC patients in China.Methods: We conducted a multicenter, cross-sectional survey in 37 tertiary hospitals in 13 provinces across China between 2012 and 2014. Each enrolled patient was interviewed using a structured questionnaire. All expenditure data were inflated to the 2014 Chinese Yuan(CNY; 1 CNY = 0.163 USD). We quantified the overall expenditure and financial burden and by subgroup(hospital type, age at diagnosis, sex, education, occupation, insurance type, household income, clinical stage, pathologic type, and therapeutic regimen). We then performed generalized linear modeling to determine the factors associated with overall expenditure.Results: A total of 2356 patients with a mean age of 57.4 years were included, 57.1 % of whom were men; 13.9% of patients had stage I cancer; and the average previous-year household income was 54,525 CNY.The overall average direct expenditure per patient was estimated to be 67,408 CNY, and the expenditures for stage Ⅰ, Ⅱ, Ⅲ, and Ⅳ disease were 56,099 CNY, 59,952 CNY, 67,292 CNY, and 82,729 CNY, respectively. Non-medical expenditure accounted for 8.3%of the overall expenditure. The 1-year out-of-pocket expenditure of a newly diagnosed patient was 32,649 CNY, which accounted for 59.9% of their previous-year household income and caused 75.0% of families to suffer an unmanageable financial burden. Univariate analysis showed that financial burden and overall expenditure differed in almost all subgroups(P < 0.05), except for sex. Multivariate analysis showed that patients who were treated in specialized hospitals and those who were diagnosed with adenocarcinoma or diagnosed at a later stage were likely to spend more,whereas those with a lower household income and those who underwent surgery spent less(all P < 0.05).Conclusions: For patients in China, direct expenditure for the diagnosis and treatment of CRC seemed catastrophic,and non-medical expenditure was non-ignorable. The financial burden varied among subgroups, especially among patients with different clinical stages of disease, which suggests that, in China, CRC screening might be cost-effective. 展开更多

Objective: Colorectal cancer(CRC) causes a substantial burden of disease in China and the evidence of economic burden triggered is fundamental for priority setting. The aim of this survey was to quantify medical expenditures and the time trends for CRC diagnosis and treatment in China.Methods: From 2012 to 2014, a hospital-based multicenter retrospective survey was conducted in 13 provinces across China. For each eligible CRC patient diagnosed from 2002 to 2011, clinical information and expenditure data were extracted using a uniform questionnaire. All expenditure data were reported in Chinese Yuan(CNY)using 2011 values.Results: Of the 14,536 CRC patients included, the average age at diagnosis was 58.2 years and 15.8% were stageI cases. The average medical expenditure per patient was estimated at 37,902 CNY [95 % confidence interval(95%CI): 37,282-38,522], and the annual average increase rate was 9.2% from 2002 to 2011(P for trend <0.001), with a cumulative increase of 2.4 times(from 23,275 CNY to 56,010 CNY). The expenditure per patient in stages Ⅰ, Ⅱ, Ⅲ and Ⅳ were 31,698 CNY, 37,067 CNY, 38,918 CNY and 42,614 CNY, respectively(P<0.001). Expenditure significantly differed within various subgroups. Expenses for drugs contributed the largest proportion(52.6%).Conclusions: These conservative estimates illustrated that medical expenditures for CRC diagnosis and treatment in tertiary hospitals in China were substantial and increased rapidly over the 10 years, with drugs continually being the main expense by 2011. Relatively, medical expenditures are lower for CRC in the earlier stages. These findings will facilitate the economic evaluation of CRC prevention and control in China. 展开更多

Background: Stage at diagnosis and molecular subtype are important clinical factors associated with breast cancer patient survival. However, subgroup survival data from a large study sample are limited in China.To estimate the survival differences among patients with different stages and various subtypes of breast cancer, we conducted a hospital-based multi-center study on breast cancer in Beijing, China.Methods: All resident patients diagnosed with primary, invasive breast cancer between January 1,2006 and December 31,2010 from four selected hospitals in Beijing were included and followed up until December 31,2015. Hospitalbased data of stage at diagnosis, hormone receptor status, and selected clinical characteristics, including body mass index(BMI), menopausal status, histological grade, and histological type, were collected from the medical records of the study subjects. Overall survival(OS) and cancer-specific survival(CSS) were estimated. Cox proportional hazards models were employed to evaluate the associations of stage at diagnosis and molecular subtype with patient survival.Results: The 5-year OS and CSS rates for all patients were 89.4% and 90.3%. Survival varied by stage and molecular subtype. The 5-year OS rates for patients with stage I, Ⅱ, Ⅲ, and IV diseases were 96.5%, 91.6%, 74.8%, and 40.7%,respectively, and the corresponding estimates of 5-year CSS rates were 97.1%, 92.6%, 75.6%, and 42.7%, respectively.The 5-year OS rates for patients with luminal A, luminal B, HER2, and triple-negative subtypes of breast cancer were92.6%, 88.4%, 83.6%, and 82.9%, respectively, and the corresponding estimates of 5-year CSS rates were 93.2%, 89.1 %,85.4%, and 83.5%, respectively. Multivariate analysis showed that stage at diagnosis and molecular subtype were important prognostic factors for breast cancer.Conclusions: Survival of breast cancer patients varied significantly by stage and molecular subtype. Cancer screening is encouraged for the early detection and early diagnosis of breast cancer. More advanced therapies and health care policies are needed on HER2 and triple-negative subtypes. 展开更多
