Irreversible electroporation is a promising non-thermal ablation method that has been shown to increase overall survival in locally advanced pancreatic cancer in some studies.However,higher quality studies with proper controls and randomization are required to establish its superiority when added with neoadjuvant chemotherapy over the current management of choice,which is chemotherapy alone.Further studies are required before establishment of any survival benefit in metastatic pancreatic carcinoma,and such evidence is lacking at present. 展开更多

BACKGROUND Pancreatic ductal adenocarcinoma(PDAC)is an aggressive lethal malignancy with limited options for treatment and a 5-year survival rate of 11%in the United States.As for other types of tumors,such as colorectal cancer,aberrant de novo lipid synthesis and reprogrammed lipid metabolism have been suggested to be associated with PDAC development and progression.AIM To identify the possible involvement of lipid metabolism in PDAC by analyzing in tumoral and non-tumoral tissues the expression level of the most relevant genes involved in the long-chain fatty acid(FA)import into cell.METHODS A gene expression analysis of FASN,CD36,SLC27A1,SLC27A2,SLC27A3,SLC27A4,SLC27A5,ACSL1,and ACSL3 was performed by qRT-PCR in 24 tumoral PDAC tissues and 11 samples from non-tumoral pancreatic tissues obtained via fine needle aspiration or via surgical resection.The genes were considered significantly dysregulated between the groups when the p value was<0.05 and the fold change(FC)was≤0.5 and≥2.RESULTS We found that three FA transporters and two long-chain acyl-CoA synthetases genes were significantly upregulated in the PDAC tissue compared to the non-tumoral tissue:SLC27A2(FC=5.66;P=0.033),SLC27A3(FC=2.68;P=0.040),SLC27A4(FC=3.13;P=0.033),ACSL1(FC=4.10;P<0.001),and ACSL3(FC=2.67;P=0.012).We further investigated any possible association between the levels of the analyzed mRNAs and the specific characteristics of the tumors,including the anatomic location,the lymph node involvement,and the presence of metastasis.A significant difference in the expression of SLC27A3(FC=3.28;P=0.040)was found comparing patients with and without lymph nodes involvement with an overexpression of this transcript in 17 patients presenting tumoral cells in the lymph nodes.CONCLUSION Despite the low number of patients analyzed,these preliminary results seem to be promising.Addressing lipid metabolism through a broad strategy could be a beneficial way to treat this malignancy.Future in vitro and in vivo studies on these genes may offer important insights into the mechanisms linking PDAC with the long-chain FA import pathway. 展开更多

Background:Hepatocellular carcinoma(HCC)is the most common cause of cancer-related death in Saudi Arabia.Our study aimed to investigate the patterns of HCC and the effect of TNM staging,Alfa-fetoprotein(AFP),and Child-Turcotte Pugh(CTP)on patients’overall survival(OS).Methods:A retrospective analysis was conducted on 43 HCC patients at a single oncology center in Saudi Arabia from 2015 to 2020.All patients had to fulfill one of the following criteria:(a)a liver lesion reported as definitive HCC on dynamic imaging and/or(b)a biopsy-confirmed diagnosis.Results:The mean patient age of all HCC cases was 66.8 with a male-to-female ratio of 3.3:1.All patients were stratified into two groups:viral HCC(n=22,51%)and non-viral HCC(n=21,49%).Among viral-HCC patients,55%were due to HBV and 45%due to HCV.Cirrhosis was diagnosed in 79%of cases.Age and sex did not significantly statistically differ in OS among viral and non-viral HCC patients(p-value>0.05).About 65%of patients had tumor size>5 cm during the diagnosis,with a significant statistical difference in OS(p-value=0.027).AFP was>400 ng/ml in 45%of the patients.There was a statistically significant difference in the OS in terms of AFP levels(p-value=0.021).A statistically significant difference was also observed between the CTP score and OS(p-value=0.02).CTP class B had the longest survival.BSC was the most common treatment provided to HCC patients followed by sorafenib therapy.There was a significant statistical difference in OS among viral and non-viral HCC patients(p-value=0.008).Conclusions:The most common predictors for OS were the underlying cause of HCC,AFP,and tumor size.Being having non-viral etiology,a tumor size>5 cm,an AFP>400 ng/mL,and a CTP score class C were all negatively associated with OS. 展开更多

Liver cancer,and in particular hepatocellular carcinoma(HCC)is a disease of rising prevalence and incidence.To date,definitive treatment options include either surgical excision or ablation of the affected area.With increasing research on several pathways that could be involved in the progression of HCC,new elements within these pathways emerge as potential targets for novel therapies.The WNT/β-catenin pathway favors the presence of M2 tumor-associated macrophages which in turn promote tumor growth and metastasis.The inhibition of this pathway is considered a good candidate for such targeted therapeutic interventions.Interestingly,as Huang et al show in their recently published article,Calculus bovis which is used in traditional Chinese medicine can exert an inhibitory effect on theβ-catenin pathway and become a potential candidate for targeted pharmacotherapy against liver cancer. 展开更多

Hepatocellular carcinoma(HCC)is a leading cause of cancer-related mortality worldwide,with advanced stages posing significant treatment challenges.Al-though hepatic arterial infusion chemotherapy(HAIC)has emerged as a promising modality for treating advanced HCC,particularly in Asian clinical practice,its adoption in Western medicine remains limited due to a lack of large-scale randomized controlled trials.This editorial reviews and comments on the meta-analysis conducted by Zhou et al,which evaluates the efficacy and safety of HAIC and its combination strategies for advanced HCC.The authors performed a comprehensive meta-analysis of various clinical trials and cohort studies comparing HAIC and its combinations to other first-line treatments,such as sorafenib and transarterial chemoembolization(TACE).In this work,HAIC showed significantly better results regarding overall survival and progression-free survival compared to sorafenib or TACE alone and their combination.HAIC in combination with lenvatinib,ablation,programmed cell death 1 inhibitors,and radiotherapy further enhanced patient outcomes,indicating a synergistic effect.This editorial focuses on the critical role of multimodal treatment strategies in managing advanced HCC.It advocates for a paradigm shift towards integrated treatment approaches to enhance survival rates and improve the quality of life in patients with advanced HCC. 展开更多

BACKGROUND Hepatocellular carcinoma(HCC)is the most common form of liver cancer that has limited treatment options and a poor prognosis.Transarterial chemoembolization(TACE)is the first-line treatment for intermediate-stage HCC but can induce tumour hypoxia,thereby promoting angiogenesis.Recent studies suggested that combining TACE with anti-angiogenic therapies and immunotherapy might im-prove efficacy.Lenvatinib,a tyrosine kinase inhibitor,has demonstrated superior outcomes compared to sorafenib,while immune checkpoint inhibitors such as sintilimab show potential when combined with TACE.However,the efficacy and safety of TACE combined with lenvatinib and sintilimab(TACE+SL)compared to TACE with lenvatinib alone(TACE+L)in patients with intermediate-ad-vanced HCC has not yet been investigated.AIM To evaluate the efficacy and safety of TACE+SL therapy in comparison to TACE+L therapy in patients with intermediate-advanced HCC.METHODS A retrospective analysis was performed on patients with intermediate-advanced HCC who received TACE plus lenvatinib with or without sintilimab between September 2019 and September 2022.Baseline characteristics were compared,and propensity score matching was applied.Overall survival(OS),progression-free survival(PFS),and objective response rate(ORR)were evaluated between the two groups,and adverse events were analyzed.RESULTS The study included 57 patients,with 30 in the TACE+SL group and 27 in the TACE+L group.The TACE+SL group demonstrated significantly improved median PFS and OS compared to the TACE+L group(PFS:14.1 months vs 9.6 months,P=0.016;OS:22.4 months vs 14.1 months,P=0.039),along with a higher ORR(70.0%vs 55.6%).After propensity score matching,30 patients were included,with the TACE+SL group again showing longer median PFS and a trend toward improved OS(PFS:14.6 months vs 9.2 months,P=0.012;OS:23.9 months vs 16.3 months,P=0.063),and a higher ORR(73.3%vs 53.3%).No severe adverse events were reported.CONCLUSION TACE+SL demonstrated superior outcomes in terms of OS and PFS,compared to TACE+L.These findings suggest that the addition of sintilimab might enhance the therapeutic response in patients with intermediate-advanced HCC. 展开更多

In this editorial,we comment on the article by Mu et al,published in the recent issue of the World Journal of Gastrointestinal Oncology.We pay special attention to the immune tolerance mechanism caused by hepatitis B virus(HBV)infection,the pathogenesis of hepatocellular carcinoma(HCC),and the role of antiviral therapy in treating HCC related to HBV infection.HBV infection leads to systemic innate immune tolerance by directly inhibiting pattern recognition receptor recognition and antiviral signaling pathways,as well as by inhibiting the immune functions of macrophages,natural killer cells and dendritic cells.In addition,HBV leads to an immunosuppressive cascade by expressing inhibitory molecules to induce exhaustion of HBV-specific cluster of differentiation 8+T cells,ultimately leading to long-term viral infection.The loss of immune cell function caused by HBV infection ultimately leads to HCC.Long-term antiviral therapy can improve the prognosis of patients with HCC and prevent tumor recurrence and metastasis. 展开更多

BACKGROUND Primary squamous cell carcinoma(SCC)of the renal parenchyma is extremely rare,with only nine cases reported.CASE SUMMARY This study reports a 51-year-old man with primary SCC of the renal parenchyma.The patient was admitted with recurrent dull pain and discomfort in the right lumbar region,which had worsened over 2 weeks,accompanied by painful gross hematuria.SCC antigen(SCCA)levels were elevated,and imaging revealed a renal mass with associated calculi.The patient underwent laparoscopic unilateral nephrectomy and lymph node dissection.Postoperative pathology confirmed highly differentiated SCC with necrosis in the right renal parenchyma,with negative renal pelvis and ureter.The pathological stage was Pt3aN1M0.Four months after surgery,the tumor recurred with involvement of the liver,right psoas major muscle,and inferior vena cava.The patient refused chemotherapy and succumbed to the disease 6 months postoperatively due to disease progression.CONCLUSION We report a case of primary SCC of the renal parenchyma,a rare renal malignancy.The clinical symptoms,laboratory tests,and imaging findings are nonspecific,making accurate and timely diagnosis challenging.According to the literature,for patients with renal calculi accompanied by a renal mass,elevated serum SCCA levels,and magnetic resonance imaging showing cystic or cystic-solid masses within the kidney with pseudocapsules and heterogeneous mild enhancement,the possibility of this disease should be considered. 展开更多

BACKGROUND Hepatocellular carcinoma(HCC)is an inflammation-associated tumor with a dismal prognosis.Immunotherapy has become an important treatment strategy for HCC,as immunity is closely related to inflammation in the tumor microenvir-onment.Inflammation regulates the expression of programmed death ligand-1(PD-L1)in the immunosuppressive tumor microenvironment and affects im-munotherapy efficacy.Interleukin-17A(IL-17A)is involved in the remodeling of the tumor microenvironment and plays a protumor or antitumor role in different tumors.We hypothesized that IL-17A participates in tumor progression by affe-cting the level of immune checkpoint molecules in HCC.The upregulation of PD-L1 expression in HCC cells by IL-17A was assessed by reverse transcription PCR,western blotting,and flow cytometry.Mechanistic studies were conducted with gene knockout models and pathway inhibitors.The function of IL-17A in immune evasion was explored through coculture of T cells and HCC cells.The effects of IL-17A on the malignant biological behaviors of HCC cells were evaluated in vitro,and the antitumor effects of an IL-17A inhibitor and its synergistic effects with a PD-L1 inhibitor were studied in vivo.RESULTS IL-17A upregulated PD-L1 expression in HCC cells in a dose-dependent manner,whereas IL-17A receptor knockout or treatment with a small mothers against decapentaplegic 2 inhibitor diminished the PD-L1 expression induced by IL-17A.IL-17A enhanced the survival of HCC cells in the coculture system.IL-17A increased the viability,G2/M ratio,and migration of HCC cells and decreased the apoptotic index.Cyclin D1,VEGF,MMP9,and Bcl-1 expression increased after IL-17A treatment,whereas BAX expression decreased.The combination of IL-17A and PD-L1 inhibitors showed synergistic antitumor efficacy and increased cluster of differentiation 8+T lymphocyte infiltration in an HCC mouse model.CONCLUSION IL-17A upregulates PD-L1 expression via the IL-17A receptor/phosphorylation-small mothers against decapenta-plegic 2 signaling pathway in HCC cells.Blocking IL-17A enhances the therapeutic efficacy of PD-L1 antibodies in HCC in vivo. 展开更多

BACKGROUND Chronic hepatitis B often progresses silently toward hepatocellular carcinoma(HCC),a leading cause of mortality worldwide.Early detection of HCC is crucial,yet challenging.AIM To investigate the role of dynamic changes in alkaline phosphatase to prealbumin ratio(APR)in hepatitis B progression to HCC.METHODS Data from 4843 patients with hepatitis B(January 2015 to January 2024)were analyzed.HCC incidence rates in males and females were compared using the log-rank test.Data were evaluated using Kaplan–Meier analysis.The Linear Mixed-Effects Model was applied to track the fluctuation of APR levels over time.Furthermore,Joint Modeling of Longitudinal and Survival data was employed to investigate the temporal relationship between APR and HCC risk.RESULTS The incidence of HCC was higher in males.To ensure the model’s normality assumption,this study applied a logarithmic transformation to APR,yielding ratio.Ratio levels were higher in females(t=5.26,P<0.01).A 1-unit increase in ratio correlated with a 2.005-fold higher risk of HCC in males(95%CI:1.653-2.431)and a 2.273-fold higher risk in females(95%CI:1.620-3.190).CONCLUSION Males are more prone to HCC,while females have higher APR levels.Despite no baseline APR link,rising APR indicates a higher HCC risk. 展开更多

In order to understand the dynamics of granular flow on an erodible base soil,in this paper,a series of material point method-based granular column collapse tests were conducted to investigate numerically the mobility and dynamic erosion process of granular flow subjected to the complex settings,i.e.,the aspect ratio,granular mass,friction and dilatancy resistance,gravity and presence of water.A set of power scaling laws were proposed to describe the final deposit characteristics of granular flow by the relations of the normalized run-out distance and the normalized final height of granular flow against the aspect ratio,being greatly affected by the complex geological settings,e.g.,granular mass,the friction and dilatancy resistance of granular soil,and presence of water in granular flow.An index of the coefficient of friction of granular soil was defined as a ratio of the target coefficient of friction over the initial coefficient of friction to quantify the scaling extent of friction change(i.e.,friction strengthening or weakening).There is a characteristic aspect ratio of granular column corresponding to the maximum mobility of granular flow with the minimum index of the apparent coefficient of friction.The index of the repose coefficient of friction of granular flow decreased gradually with the increase in aspect ratio because higher potential energy of granular column at a larger aspect ratio causes a larger kinetic energy of granular soil to weaken the friction of granular soil as a kind of velocity-related friction weakening.An increase in granular mass reduces gradually the indexes of the apparent and repose coefficients of friction of granular soil to enhance the mobility of granular flow.The mobility of granular flow increases gradually with the decrease in friction angle or increase in dilatancy angle of granular soil.However,the increase of gravity accelerates granular flow but showing the same final deposit profile without any dependence on gravity.The mobility of granular flow increases gradually by lowering the indexes of the apparent and repose coefficients of friction of granular flow while changing the surroundings,in turn,the dry soil,submerged soil and saturated soil,implying a gradually increased excessive mobility of granular flow with the friction weakening of granular soil.Presence of water in granular flow may be a potential catalyzer to yield a long run-out granular flow,as revealed in comparison of water-absent and water-present granular flows.In addition,the dynamic erosion and entrainment of based soil induced by granular flow subjected to the complex geological settings,i.e.,the aspect ratio,granular mass,gravity,friction and dilatancy resistance,and presence of water,were comprehensively investigated as well. 展开更多

We present a short retrospective review of the existing literature about the dynamics of(dry)granular matter under the effect of vibrations.The main objective is the development of an integrated resource where vital information about past findings and recent discoveries is provided in a single treatment.Special attention is paid to those works where successful synthetic routes to as-yet unknown phenomena were identified.Such landmark results are analyzed,while smoothly blending them with a history of the field and introducing possible categorizations of the prevalent dynamics.Although no classification is perfect,and it is hard to distillate general properties out of specific observations or realizations,two possible ways to interpret the existing results are defined according to the type of forcing or the emerging(ensuing)regime of motion.In particular,first results concerning the case where vibrations and gravity are concurrent(vertical shaking)are examined,then the companion situation with vibrations perpendicular to gravity(horizontal shaking)is described.Universality classes are introduced as follows:(1)Regimes where sand self-organizes leading to highly regular geometrical“pulsating”patterns(thin layer case);(2)Regimes where the material undergoes“fluidization”and develops an internal multicellular convective state(tick layers case);(3)Regimes where the free interface separating the sand from the overlying gas changes inclination or develops a kind a patterned configuration consisting of stable valleys and mountains or travelling waves;(4)Regimes where segregation is produced,i.e.,particles of a given size tend to be separated from the other grains(deep containers).Where possible,an analogy or parallelism is drawn with respect to the companion field of fluid-dynamics for which the assumption of“continuum”can be applied. 展开更多

Hepatocellular carcinoma(HCC)is one of the most common causes of cancerrelated mortality.This particular type of cancer has the distinctive characteristic of mostly happening in individuals with an underlying liver disease.This makes the management of patients more challenging,since physicians must take into consideration two different conditions,the chronic liver disease and the tumor.The underlying liver disease has several implications in clinical practice,because different kinds of chronic liver disease can lead to varying degrees of risk of developing HCC,obstacles in surveillance,and differences in the efficacy of the treatment against HCC.A shift in the prevalence of liver diseases has been evident over the last few years,with viral hepatitis gradually losing the leading position as cause of HCC and metabolic dysfunction-associated steatotic liver disease gaining importance.Therefore,in an era of personalized medicine,it is imperative that physicians are aware of the underlying liver disease of individuals with HCC and its impact in the management of their tumors. 展开更多

Hepatocellular carcinoma(HCC)is a high mortality neoplasm which usually appears on a cirrhotic liver.The therapeutic arsenal and subsequent prognostic outlook are intrinsically linked to the HCC stage at diagnosis.Notwithstanding the current deployment of treatments with curative intent(liver resection/local ablation and liver transplantation)in early and intermediate stages,a high rate of HCC recurrence persists,underscoring a pivotal clinical challenge.Emergent systemic therapies(ST),particularly immunotherapy,have demonstrate promising outcomes in terms of increase overall survival,but they are currently bound to the advanced stage of HCC.This review provides a comprehensive analysis of the literature,encompassing studies up to March 10,2024,evaluating the impact of novel ST in the early and intermediate HCC stages,specially focusing on the findings of neoadjuvant and adjuvant regimens,aimed at increasing significantly overall survival and recurrence-free survival after a treatment with curative intent.We also investigate the potential role of ST in enhancing the downstaging rate for the intermediate-stage HCC initially deemed ineligible for treatment with curative intent.Finally,we critically discuss about the current relevance of the results of these studies and the encouraging future implications of ST in the treatment schedules of early and intermediate HCC stages. 展开更多

AIM:To evaluate lacrimal gland adenoid cystic carcinoma(LGACC)of prognosis in patients who underwent different treatment regimens.METHODS:We searched PubMed,EMBASE,and the Cochrane Library for studies done on the treatment of LGACC,between January 1987 and April 2022.A Metaanalysis was conducted to pool the 5-year overall survival rate(OR),and the 5-year recurrence rate(RR)and 5-year metastasis rate(MR)were assessed.RESULTS:The 30 studies involved 585 patients were included in the Meta-analysis.The pooled 5-year OR with surgery alone was 50%,the 5-year RR was 63%,and the 5-year MR was 34%.The pooled 5-year OR with surgery and adjuvant radiotherapy combined was 67%(95%CI 61%,73%),the 5-year RR was 41%,and the 5-year MR was 35%.The pooled 5-year OR with surgery and adjuvant chemoradiotherapy combined was 72%(95%CI 59%,84%),the 5-year RR was 48%,and the 5-year MR was 36%.The pooled 5-year OR with surgery,intra-arterial cytoreductive chemotherapy,and adjuvant chemoradiotherapy combined was 78%(95%CI 68%,89%),the 5-year RR was 15%,and the 5-year MR was 27%.CONCLUSION:Comprehensive treatment is more effective than surgery alone.Surgery combined with intraarterial chemotherapy and adjuvant chemoradiotherapy seems to add value to the therapeutic effect of comprehensive treatment of LGACC but further high-quality research is required to validate this. 展开更多

The high rate of early recurrence in hepatocellular carcinoma(HCC)post curative surgical intervention poses a substantial clinical hurdle,impacting patient outcomes and complicating postoperative management.The advent of machine learning provides a unique opportunity to harness vast datasets,identifying subtle patterns and factors that elude conventional prognostic methods.Machine learning models,equipped with the ability to analyse intricate relationships within datasets,have shown promise in predicting outcomes in various medical disciplines.In the context of HCC,the application of machine learning to predict early recurrence holds potential for personalized postoperative care strategies.This editorial comments on the study carried out exploring the merits and efficacy of random survival forests(RSF)in identifying significant risk factors for recurrence,stratifying patients at low and high risk of HCC recurrence and comparing this to traditional COX proportional hazard models(CPH).In doing so,the study demonstrated that the RSF models are superior to traditional CPH models in predicting recurrence of HCC and represent a giant leap towards precision medicine. 展开更多
