Adherence to the EASL guidelines started relatively high, ranging from 77% to 80% between 2008 and2012, but it gradually declined to 58.8% to 71.6% from 2013 to 2016. Adherence to the AASLD guidelines began at71.7% to 75.9% from 2008 to 2010, and then it fluctuated between 49.2% and 73.8% from 2011 to 2016. In contrast,adherence to the APASL guidelines remained consistently high, staying within the range of 90.14% to 94.5%throughout the entire study period. Upward treatment, for example with liver resection, liver transplantation, orradiofrequency ablation, significantly improved the survival of patients with BCLC stage B HCC compared to thatof patients treated in adherence to the guidelines (for patients analyzed according to the 2000 EASL guidelines, the5-year survival rates were 63.4% vs 27.2%, P < 0.001), although results varied depending on the guidelines.Progression-free survival rates were also significantly improved upon the use of upward treatments in certaingroups. Patients receiving upward treatments were typically < 70 years old, had platelet counts > 105/μL, andserum albumin levels ≥ 3.5 g/dL.CONCLUSIONAdherence to guidelines significantly influences survival in South Korean stage B HCC patients. Curativetreatments outperform TACE, but liver resection should be selected with caution due to disease heterogeneity.展开更多

Many regions across the world have issued various HCC diagnosis and treatment protocols to improve the diagnosis and targeted treatment of patients with HCC. However, real-world studies analysing the practice, application value, and existing problems of the China Liver Cancer(CNLC) staging system are scarce.AIM To analyze the current situation and problems associated with the Guidelines for Diagnosis and Treatment of Primary Liver Cancer in China.METHODS We collected the medical records of all patients with HCC admitted to the First Affiliated Hospital of Zhengzhou University from January 1, 2011 to December 31, 2019, and recorded the hospitalization information of those patients until December 31, 2020. All information on the diagnosis and treatment of the target patients was recorded, and their demographic and sociological characteristics, CNLC stages, screening situations, and treatment methods and effects were analyzed. The survival status of the patients was obtained from follow-up data.RESULTS This study included the medical records of 3022 patients with HCC. Among these cases, 304 patients were screened before HCC diagnosis;their early-stage diagnosis rate was 69.08%, which was significantly higher than that of patients with HCC who were diagnosed without screening and early detection(33.74%). Herein, patients with no clinical outcome at discharge were followed up, and the survival information of 1128 patients was obtained. A Cox model was used to analyse independent risk factors affecting overall survival, which were revealed as age > 50 years, no screening, alpha-fetoprotein > 400 ng/mL, Child–Pugh grade B, and middle and late CNLC stages. Based on the Cox model survival analysis, in our study, patients with HCC identified via screening had significant advantages in overall and tumorfree survival after hepatectomy.CONCLUSION Early diagnosis and treatment can be achieved by screening groups at high risk for HCC based on the guidelines;however, real-world compliance is poor.展开更多

The Barcelona Clinic Liver Cancer classification is used to guide the treatment of hepatocellular carcinoma. The aim of this retrospective study was to describe the Barcelona Clinic Liver Cancer classification and the treatment of hepatocellular carcinoma in a University Hospital in Côte d’Ivoire. Methods: Patients with hepatocellular carcinoma hospitalized in the hepato-gastroenterology unit of the University Hospital of Yopougon from 01 January 2012 to 30 June 2017 were included. The diagnosis of hepatocellular carcinoma was based on the presence of hepatic nodules on the abdominal ultrasound scan, typical images with the helical scanner associated or not with an increase of the α-fetoprotein higher than 200 ng/ml or with histology. Demographic, clinical, biological and radiological data were determined at the time of diagnosis. Patients were classified according to the Barcelona Clinic Liver Cancer classification. Their treatment was specified. Results: There were 258 patients whose median age was 48.1 years. Viral hepatitis B virus was the primary cause of hepatocellular carcinoma in 64.7% of cases. The severity of the underlying cirrhosis was Child-Pugh A in 12.1%, B in 63.6% and C in 24.3% of cases. The median size of the tumor was 63 mm. The α-fetoprotein level was higher than 200 mg/ml in 56.03% of cases. The Eastern Cooperative Oncology Group (ECOG)/World Health Organization (WHO) system was ≥2 in 82.9%. The Barcelona Clinic Liver Cancer classification was A in 1.3%, B in 0%, C in 55.2% and D in 43.5% of patients. There was no transplantation or hepatic resection. Very few patients (1.9%) received radio-frequency curative therapy. The treatment was predominantly symptomatic in 97.8% of patients. During hospitalization 43.7% of patients died. Conclusion: Hepatocellular carcinoma occurs on a liver with severe cirrhosis at a late stage. This does not allow cure treatment and explains a high mortality rate during hospitalization. Hepatitis B virus is the main risk factor and immunization at birth will reduce the incidence of this cancer in Africa.展开更多

METHODS:A 31-year-old man presented with severe hematemesis secondary to liver cirrhosis.Over a course of 8 years,his liver decompensated and required an orthotopic liver transplantation. In this report we discuss his disease presentation,course of management,and the post-transplantation course of manage- ment,and review the morphologic diagnosis,and differential diagnosis of the disease with large-duct type and other diseases that involve small intrahepatic bile ducts. RESULTS:The patient’s explanted liver showed changes of PSC affecting only the small-and medium-sized bile ducts in addition to three incidental nodules of hepatocellular carcinoma. CONCLUSIONS:Small-duct PSC has a substantially better prognosis than the large-duct type,with less chance of developing cirrhosis and an equal risk for developing hepato- cellular carcinoma,but no increased risk for developing cholangiocarcinoma.Treatment seems to help relieve the symptoms but not necessarily improve survival.Liver transplantation remains the ultimate cure.展开更多

文摘As a highly aggressive tumor,the pathophysiological mechanism of primary liver cancer has attracted much attention.In recent years,factors such as ferroptosis regulation,lipid peroxidation and metabolic abnormalities have emerged in the study of liver cancer,providing a new perspective for understanding the development of liver cancer.Ferroptosis regulation,lipid peroxidation and metabolic abnormalities play important roles in the occurrence and development of liver cancer.The regulation of ferroptosis is involved in apoptosis and necrosis,affecting cell survival and death.Lipid peroxidation promotes oxidative damage and promotes the invasion of liver cancer cells.Metabolic abnormalities,especially the disorders of glucose and lipid metabolism,directly affect the proliferation and growth of liver cancer cells.Studies of ferroptosis regulation and lipid peroxidation may help to discover new therapeutic targets and improve therapeutic outcomes.The understanding of metabolic abnormalities can provide new ideas for the prevention of liver cancer,and reduce the risk of disease by adjusting the metabolic process.This review focuses on the key roles of ferroptosis regulation,lipid peroxidation and metabolic abnormalities in this process.
文摘BACKGROUND This study was designed to investigate the clinical efficacy and safety of Gamma Knife®combined with transarterial chemoembolization(TACE)and immunotherapy in the treatment of primary liver cancer.AIM To investigate the clinical efficacy and safety of Gamma Knife®combined with TACE and immune-targeted therapy in the treatment of primary liver cancer.METHODS Clinical data from 51 patients with primary liver cancer admitted to our hospital between May 2018 and October 2022 were retrospectively collected.All patients underwent Gamma Knife®treatment combined with TACE and immunotherapy.The clinical efficacy,changes in liver function,overall survival(OS),and progression-free survival(PFS)of patients with different treatment responses were evaluated,and adverse reactions were recorded.RESULTS The last follow-up for this study was conducted on October 31,2023.Clinical evaluation of the 51 patients with primary liver cancer revealed a partial response(PR)in 27 patients,accounting for 52.94%(27/51);stable disease(SD)in 16 patients,accounting for 31.37%(16/51);and progressive disease(PD)in 8 patients,accounting for 15.69%(8/51).The objective response rate was 52.94%,and the disease control rate was 84.31%.Alanine aminotransferase,aspartate aminotransferase,lactate dehydrogenase,and alpha-fetoprotein isoform levels decreased after treatment compared with pretreatment(all P=0.000).The median OS was 26 months[95%confidence interval(95%CI):19.946-32.054]in the PR group and 19 months(95%CI:14.156-23.125)in the SD+PD group,with a statistically significant difference(P=0.015).The median PFS was 20 months(95%CI:18.441-34.559)in the PR group and 12 months(95%CI:8.745-13.425)in the SD+PD group,with a statistically significant difference(P=0.002).Common adverse reactions during treatment included nausea and vomiting(39.22%),thrombocytopenia(27.45%),and leukopenia(25.49%),with no treatment-related deaths reported.CONCLUSION Gamma Knife®combined with TACE and immune-targeted therapy is safe and effective in the treatment of primary liver cancer and has a good effect on improving the clinical benefit rate and liver function of patients.

文摘BACKGROUND Hepatocellular carcinoma(HCC)and intrahepatic cholangiocarcinoma(ICC)represent the predominant histological types of primary liver cancer,comprising over 99%of cases.Given their differing biological behaviors,prognoses,and treatment strategies,accurately differentiating between HCC and ICC is crucial for effective clinical management.Radiomics,an emerging image processing technology,can automatically extract various quantitative image features that may elude the human eye.Reports on the application of ultrasound(US)-based radiomics methods in distinguishing HCC from ICC are limited.METHODS In our retrospective study,we included a total of 280 patients who were diagnosed with ICC(n=140)and HCC(n=140)between 1999 and 2019.These patients were divided into training(n=224)and testing(n=56)groups for analysis.US images and relevant clinical characteristics were collected.We utilized the XGBoost method to extract and select radiomics features and further employed a random forest algorithm to establish ultrasomics models.We compared the diagnostic performances of these ultrasomics models with that of radiologists.RESULTS Four distinct ultrasomics models were constructed,with the number of selected features varying between models:13 features for the US model;15 for the contrast-enhanced ultrasound(CEUS)model;13 for the combined US+CEUS model;and 21 for the US+CEUS+clinical data model.The US+CEUS+clinical data model yielded the highest area under the receiver operating characteristic curve(AUC)among all models,achieving an AUC of 0.973 in the validation cohort and 0.971 in the test cohort.This performance exceeded even the most experienced radiologist(AUC=0.964).The AUC for the US+CEUS model(training cohort AUC=0.964,test cohort AUC=0.955)was significantly higher than that of the US model alone(training cohort AUC=0.822,test cohort AUC=0.816).This finding underscored the significant benefit of incorporating CEUS information in accurately distin-guishing ICC from HCC.CONCLUSION We developed a radiomics diagnostic model based on CEUS images capable of quickly distinguishing HCC from ICC,which outperformed experienced radiologists.
文摘Objective:To explore the effect of transarterial chemoembolization(TACE)+CT-guided microwave ablation(MWA)on treating patients with primary liver cancer.Methods:78 primary liver cancer cases were enrolled and divided into groups according to their assigned surgical plans.The control group was treated with TACE alone,and the observation group was treated with TACE+CT-guided MWA.The efficacy of the treatment and the liver function indicators and follow-up results of the patients of the two groups were compared.Results:The efficacy of the treatment received by the observation group was higher than that of the control group.Besides,the patients in the observation group exhibited better improvement in liver function indicators after 3 months of treatment.Furthermore,the survival rates of 1 and 2 years after surgery of the observation group were all higher than those of the control group(P<0.05).Conclusion:TACE combined with CT-guided MWA is more effective in treating primary liver cancer compared to TACE alone.Besides,it resulted in better improvement of liver function and long-term survival rate.Therefore,this treatment regime should be popularized.
文摘Transarterial radioembolization or selective internal radiation therapy(SIRT)has emerged as a minimally invasive approach for the treatment of tumors.This percutaneous technique involves the local,intra-arterial delivery of radioactive microspheres directly into the tumor.Historically employed as a palliative measure for liver malignancies,SIRT has gained traction over the past decade as a potential curative option,mirroring the increasing role of radiation segmentectomy.The latest update of the BCLC hepatocellular carcinoma guidelines recognizes SIRT as an effective treatment modality comparable to other local ablative methods,particularly well-suited for patients where surgical resection or ablation is not feasible.Radiation segmentectomy is a more selective approach,aiming to deliver high-dose radiation to one to three specific hepatic segments,while minimizing damage to surrounding healthy tissue.Future research efforts in radiation segmentectomy should prioritize optimizing radiation dosimetry and refining the technique for super-selective administration of radiospheres within the designated hepatic segments.

文摘BACKGROUND At present,liver transplantation(LT)is one of the best treatments for hepatocellular carcinoma(HCC).Accurately predicting the survival status after LT can significantly improve the survival rate after LT,and ensure the best way to make rational use of liver organs.AIM To develop a model for predicting prognosis after LT in patients with HCC.METHODS Clinical data and follow-up information of 160 patients with HCC who underwent LT were collected and evaluated.The expression levels of alphafetoprotein(AFP),des-gamma-carboxy prothrombin,Golgi protein 73,cytokeratin-18 epitopes M30 and M65 were measured using a fully automated chemiluminescence analyzer.The best cutoff value of biomarkers was determined using the Youden index.Cox regression analysis was used to identify the independent risk factors.A forest model was constructed using the random forest method.We evaluated the accuracy of the nomogram using the area under the curve,using the calibration curve to assess consistency.A decision curve analysis(DCA)was used to evaluate the clinical utility of the nomograms.RESULTS The total tumor diameter(TTD),vascular invasion(VI),AFP,and cytokeratin-18 epitopes M30(CK18-M30)were identified as important risk factors for outcome after LT.The nomogram had a higher predictive accuracy than the Milan,University of California,San Francisco,and Hangzhou criteria.The calibration curve analyses indicated a good fit.The survival and recurrence-free survival(RFS)of high-risk groups were significantly lower than those of low-and middle-risk groups(P<0.001).The DCA shows that the model has better clinical practicability.CONCLUSION The study developed a predictive nomogram based on TTD,VI,AFP,and CK18-M30 that could accurately predict overall survival and RFS after LT.It can screen for patients with better postoperative prognosis,and improve longterm survival for LT patients.
文摘BACKGROUND Low grade serous carcinoma of the ovary(LGSOC)is a rare type of epithelial ovarian cancer with a low incidence rate.The origin of ovarian cancer has always been a hot topic in gynecological oncology research,and some scholars believe that the origin of ovarian malignant tumors is the fallopian tubes.Primary fallopian tube cancer is the lowest incidence of malignant tumors in the female reproductive system.There are only a few reports in the literature,but the mortality rate is very high.But in clinical practice,fallopian tube cancer is very common,but in most cases,it is classified as ovarian cancer.CASE SUMMARY We report a 54 years old postmenopausal woman who was hospitalized with a lower abdominal mass and underwent surgical treatment.The final pathological confirmation was low-grade serous carcinoma of the right ovary and low-grade serous carcinoma of the left fallopian tube.No special treatment was performed after the surgery,and the patient was instructed to undergo regular follow-up without any signs of disease progression.CONCLUSION The prognosis of LGSOC is relatively good,over 80%of patients still experience disease recurrence.

文摘BACKGROUND Patients with Barcelona clinic liver cancer(BCLC)stage B hepatocellular carcinoma(HCC)are considerably heterogeneous in terms of tumor burden,liver function,and performance status.To improve the poor survival outcomes of these patients,treatment approaches other than transarterial chemoembolization(TACE),which is recommended by HCC guidelines,have been adopted in realworld clinical practice.We hypothesize that this non-adherence to treatment guidelines,particularly with respect to the use of liver resection,improves survival in patients with stage B HCC.AIM To assess guideline adherence in South Korean patients with stage B HCC and study its impact on survival.METHODS A retrospective analysis was conducted using data from 2008 to 2016 obtained from the Korea Central Cancer Registry.Patients with stage B HCC were categorized into three treatment groups,guideline-adherent,upward,and downward,based on HCC guidelines recommended by the Asian Pacific Association for the Study of the Liver(APASL),the European Association for the Study of the Liver(EASL),and the American Association for the Study of Liver Diseases(AASLD).The primary outcome was HCC-related deaths;tumor recurrence served as the secondary outcome.Survival among the groups was compared using the Kaplan-Meier method and the log-rank test.Predictors of survival outcomes were identified using multivariable Cox regression analysis.RESULTS In South Korea, over the study period from 2008 to 2016, a notable trend was observed in adherence to HCCguidelines. Adherence to the EASL guidelines started relatively high, ranging from 77% to 80% between 2008 and2012, but it gradually declined to 58.8% to 71.6% from 2013 to 2016. Adherence to the AASLD guidelines began at71.7% to 75.9% from 2008 to 2010, and then it fluctuated between 49.2% and 73.8% from 2011 to 2016. In contrast,adherence to the APASL guidelines remained consistently high, staying within the range of 90.14% to 94.5%throughout the entire study period. Upward treatment, for example with liver resection, liver transplantation, orradiofrequency ablation, significantly improved the survival of patients with BCLC stage B HCC compared to thatof patients treated in adherence to the guidelines (for patients analyzed according to the 2000 EASL guidelines, the5-year survival rates were 63.4% vs 27.2%, P < 0.001), although results varied depending on the guidelines.Progression-free survival rates were also significantly improved upon the use of upward treatments in certaingroups. Patients receiving upward treatments were typically < 70 years old, had platelet counts > 105/μL, andserum albumin levels ≥ 3.5 g/dL.CONCLUSIONAdherence to guidelines significantly influences survival in South Korean stage B HCC patients. Curativetreatments outperform TACE, but liver resection should be selected with caution due to disease heterogeneity.

文摘BACKGROUND Hepatocellular carcinoma(HCC) is a common malignant tumor worldwide. Many regions across the world have issued various HCC diagnosis and treatment protocols to improve the diagnosis and targeted treatment of patients with HCC. However, real-world studies analysing the practice, application value, and existing problems of the China Liver Cancer(CNLC) staging system are scarce.AIM To analyze the current situation and problems associated with the Guidelines for Diagnosis and Treatment of Primary Liver Cancer in China.METHODS We collected the medical records of all patients with HCC admitted to the First Affiliated Hospital of Zhengzhou University from January 1, 2011 to December 31, 2019, and recorded the hospitalization information of those patients until December 31, 2020. All information on the diagnosis and treatment of the target patients was recorded, and their demographic and sociological characteristics, CNLC stages, screening situations, and treatment methods and effects were analyzed. The survival status of the patients was obtained from follow-up data.RESULTS This study included the medical records of 3022 patients with HCC. Among these cases, 304 patients were screened before HCC diagnosis;their early-stage diagnosis rate was 69.08%, which was significantly higher than that of patients with HCC who were diagnosed without screening and early detection(33.74%). Herein, patients with no clinical outcome at discharge were followed up, and the survival information of 1128 patients was obtained. A Cox model was used to analyse independent risk factors affecting overall survival, which were revealed as age > 50 years, no screening, alpha-fetoprotein > 400 ng/mL, Child–Pugh grade B, and middle and late CNLC stages. Based on the Cox model survival analysis, in our study, patients with HCC identified via screening had significant advantages in overall and tumorfree survival after hepatectomy.CONCLUSION Early diagnosis and treatment can be achieved by screening groups at high risk for HCC based on the guidelines;however, real-world compliance is poor.

文摘BACKGROUND Transarterial chemoembolization(TACE)is an effective treatment for primary hepatocellular carcinoma(PHC).Radioactive iodine therapy has been used in the treatment of advanced PHC,especially in patients with portal vein tumor thrombosis.However,data on the therapeutic effect of TACE combined with radioactive iodine therapy in PHC are scarce.AIM To investigate the clinical efficacy of TACE combined with radioactive iodine implantation therapy in advanced PHC via perfusion computed tomography(CT).METHODS For this study,98 advanced PHC patients were recruited and divided randomly into the study and control groups.Patients in the study group were treated with TACE combined radioactive iodine implantation therapy.Patients in the control group were treated with only TACE.The tumor lesion length,clinical effect,serum alpha-fetoprotein(AFP)and CT perfusion parameters were compared before and after therapy,and statistical analysis was performed.RESULTS There was no significant difference in tumor length and serum AFP between the study and control groups(P>0.05)before treatment.However,the tumor length and serum AFP in the study group were lower than those in the control group 1 mo and 3 mo after therapy.After 3 mo of treatment,the complete and partial remission rate of the study group was 93.88%,which was significantly higher than the control group(77.55%)(P<0.05).Before treatment,there were no significant differences between the two groups on the perfusion CT variables,including the lesion blood volume,permeability surface,blood flow,hepatic artery flow and mean transit time(P>0.05).After 3 mo of treatment,all perfusion CT variables were lower in the study group compared to the control group(P<0.05).The survival time of patients in the study group was 22 mo compared to 18 mo in the control group,which was significantly different[log rank(Mantel-Cox)=4.318,P=0.038].CONCLUSION TACE combined with radioactive iodine implantation in the treatment of advanced PHC can inhibit the formation of blood vessels in tumor tissue and reduce the perfusion level of tumor lesions,thereby improving the clinical efficacy and prolonging the survival time of patients.
文摘Hepatocellular(HCC)and intrahepatic cholangiocarcinoma(ICC),the most common primary tumors of the liver,are among the most important causes of cancer deaths worldwide.Because patients with primary liver tumors are frequently diagnosed at an advanced stage and have high mortality,many efforts have been made to identify new markers to determine their behavior and treatment,similar to those in other solid organ tumors.Recently,morphological assessment of tumor budding(TB)has been revealed as a promising prognostic finding to predict tumor behavior and survival across several different tumor types.Currently,the TB score in colorectal cancer has been revealed as an important parameter in pathology report protocols to determine the course of the disease.Regarding the liver,despite enormous data showing that many mechanisms involved in TB are associated with tumor behavior in both HCC and ICC,studies focusing on the role of TB in predicting the behavior and prognosis of these tumors have started to be investigated very recently.The purpose of this review is to present data about TB in primary tumors of the liver,pointing out the potential role of this parameter in determining the course of the disease,and emphasize the need to increase the number of further studies focusing on the evaluation of this parameter with an overview of the mechanisms involved in TB.
文摘Liver malignancy,including primary liver cancer and metastatic liver cancer has become one of the most common causes of cancer-related death worldwide due to the high malignant degree and limited systematic treatment strategy.Radioembolization with yttrium-90(^(90)Y)-loaded microspheres is a relatively novel technology that has made significant progress in the local treatment of liver malignancy.The different steps in the extensive work-up of radioembolization for patients with an indication for treatment with^(90)Y microspheres,from patient selection to follow up,both technically and clinically,are discussed in this paper.It describes the application and development of^(90)Y microspheres in the treatment of liver cancer.

文摘Context/Objectives: Hepatocellular carcinoma occurs mainly and increasingly in developing countries, where the prognosis is particularly poor. The Barcelona Clinic Liver Cancer classification is used to guide the treatment of hepatocellular carcinoma. The aim of this retrospective study was to describe the Barcelona Clinic Liver Cancer classification and the treatment of hepatocellular carcinoma in a University Hospital in Côte d’Ivoire. Methods: Patients with hepatocellular carcinoma hospitalized in the hepato-gastroenterology unit of the University Hospital of Yopougon from 01 January 2012 to 30 June 2017 were included. The diagnosis of hepatocellular carcinoma was based on the presence of hepatic nodules on the abdominal ultrasound scan, typical images with the helical scanner associated or not with an increase of the α-fetoprotein higher than 200 ng/ml or with histology. Demographic, clinical, biological and radiological data were determined at the time of diagnosis. Patients were classified according to the Barcelona Clinic Liver Cancer classification. Their treatment was specified. Results: There were 258 patients whose median age was 48.1 years. Viral hepatitis B virus was the primary cause of hepatocellular carcinoma in 64.7% of cases. The severity of the underlying cirrhosis was Child-Pugh A in 12.1%, B in 63.6% and C in 24.3% of cases. The median size of the tumor was 63 mm. The α-fetoprotein level was higher than 200 mg/ml in 56.03% of cases. The Eastern Cooperative Oncology Group (ECOG)/World Health Organization (WHO) system was ≥2 in 82.9%. The Barcelona Clinic Liver Cancer classification was A in 1.3%, B in 0%, C in 55.2% and D in 43.5% of patients. There was no transplantation or hepatic resection. Very few patients (1.9%) received radio-frequency curative therapy. The treatment was predominantly symptomatic in 97.8% of patients. During hospitalization 43.7% of patients died. Conclusion: Hepatocellular carcinoma occurs on a liver with severe cirrhosis at a late stage. This does not allow cure treatment and explains a high mortality rate during hospitalization. Hepatitis B virus is the main risk factor and immunization at birth will reduce the incidence of this cancer in Africa.
文摘We report a case of metachronous multiple primary malignancies involving both rectum and liver with colonic metastasis from hepatocellular carcinoma(HCC) through hematogenous pathway.A 72-year-old woman was admitted to the emergency department with right upper abdominal pain for 4 h.Considering her surgical history of Mile's procedure plus liver resection for rectal cancer with liver metastasis three years ago and the finding of urgent computed tomography scan on admission,the preoperative diagnosis was spontaneous rupture of rectal liver metastasis located in caudate lobe and colonic metastasis from rectal cancer. The patient underwent an emergency isolated caudate lobectomy at a hemorrhagic shock status.Pathology reported a primary HCC in the caudate lobe and colonic metastasis of HCC with tumor embolus in the surrounding vessels of the intestine.No regional lymph node involvement was found.It is hypothesized that HCC may disseminate hematogenously to the ascending colon,thus making it a rare case.
文摘BACKGROUND:Primary sclerosing cholangitis(PSC)is a chronic progressive cholestatic liver disease,which usually affects young adults and is diagnosed by cholangiography.On a few occasions,the disease either starts in or exclusively involves the small intrahepatic bile ducts,referred to as small-duct PSC. METHODS:A 31-year-old man presented with severe hematemesis secondary to liver cirrhosis.Over a course of 8 years,his liver decompensated and required an orthotopic liver transplantation. In this report we discuss his disease presentation,course of management,and the post-transplantation course of manage- ment,and review the morphologic diagnosis,and differential diagnosis of the disease with large-duct type and other diseases that involve small intrahepatic bile ducts. RESULTS:The patient’s explanted liver showed changes of PSC affecting only the small-and medium-sized bile ducts in addition to three incidental nodules of hepatocellular carcinoma. CONCLUSIONS:Small-duct PSC has a substantially better prognosis than the large-duct type,with less chance of developing cirrhosis and an equal risk for developing hepato- cellular carcinoma,but no increased risk for developing cholangiocarcinoma.Treatment seems to help relieve the symptoms but not necessarily improve survival.Liver transplantation remains the ultimate cure.
文摘Noncoding RNAs instruct the Cas9 nuclease to site speifillyl cleave DNA in the CRISPR/Cas9 system.Despite the high incidence of hepatocellular carcinoma(HCC),the patient's outcome is poor.As a result of the emergence of therapeutic resistance in HCC patients,dlinicians have faced difficulties in treating such tumor.In addition,CRISPR/Cas9 screens were used to identify genes that improve the dlinical response of HCC patients.It is the objective of this article to summarize the current understanding of the use of the CRISPR/Cas9 system for the treatment of cancer,with a particular emphasis on HCC as part of the current state of knowledge.Thus,in order to locate recent developments in oncology research,we examined both the Scopus database and the PubMed database.The ability to selectively interfere with gene expression in combinatorial CRISPR/Cas9 screening can lead to the discovery of new effective HCC treatment regimens by combining clinically approved drugs.Drug resistance can be overcome with the help of the CRISPR/Cas9 system.HCC signature genes and resistance to treatment have been uncovered by genome-scale CRISPR activation screening although this method is not without limitations.It has been extensively examined whether CRISPR can be used as a tool for disease research and gene therapy.CRISPR and its applications to tumor research,particularly in HCC,are examined in this study through a review of the literature.
