Clinical trials indicate that growth factor receptors and their related signalling pathways play important roles in HCC cancer etiology and progression, thus providing rational targets for innovative cancer therapies. A number of strategies including monoclonal antibodies, tyrosine kinase inhibitors （＂small molecule inhibitors＂） and antisense oligonucleotides have already been evaluated for their potency to inhibit the activity and downstream signalling cascades of these receptors in HCC. First clinical trials have also shown that multi-kinase inhibition is an effective novel treatment strategy in HCC. In this respect sorafenib, an inhibitor of Raf-, VEGF- and PDGF-signalling, is the first multi-kinase inhibitor that has been approved by the FDA for the treatment of advanced HCC. Moreover, the serine-threonine kinase of mammalian target of rapamycin （mTOR） upon which the signalling of several growth factor receptors converge plays a central role in cancer cell proliferation, roTOR inhibition of HCC is currently also being studied in preclinical trials. As HCCs represent hypervascularized neoplasms, inhibition of tumour vessel formation via interfering with the VEGF/VEGFR system is another promising approach in HCC treatment. This review will summarize the current status of the various growth factor receptor-based treatment strategies and in view of the multitude of novel targeted approaches, the rationale for combination therapies for advanced HCC treatment will also be taken into account.展开更多

METHODS: A total of 127 cirrhotics, stages A-B, due to chronic viral infections and with advanced HCC, were enrolled in the study. Scintigraphy with 111Indium labeled octreotide was performed in all cases. The patients with increased accumulation of radionuclear compound were randomized to receive either oral placebo only or octreotide/octreotide LAR only as follows: octreotide 0.5mg s.c. every 8 h for 6 wk, at the end of wk 4-8 octreotide LAR 20 mg i.m. and at the end of wk 12 and every 4 wk octreotide LAR 30mg i.m.. Follow-up was worked out monthly as well as the estimation of quality of life (QLQ-C30 questionnaire). Patients with negative somatostatin receptors (SSTR) detection were followed up in the same manner. RESULTS: Scintigraphy demonstrated SSTR in 61 patients. Thirty were randomized to receive only placebo and 31 only octreotide. A significantly higher survival time was observed for the octreotide group (49 ± 6 wk) as compared to the control group (28 ± 1 wk) and to the SSTR negative group (28 ± 2 wk), LR = 20.39, df = 2, P < 0.01. The octreotide group presented 68.5% lower hazard ratio [95% CI (47.4%-81.2%)]. During the f irst year, a 22%, 39% and 43% decrease in the QLQ-C30 score was observed in each group respectively.CONCLUSION: The proposed therapeutic approach has shown to improve the survival and quality of life in SSTR positive patients with advanced HCC.展开更多

METHODSThis retrospective study characterizes 573 stage I/II HCC patients treated with liver resection in 3 tertiary-referral centers: Tokyo (n = 250), Honolulu (n = 146) and Shanghai (n = 177). RESULTSShanghai patients were younger, predominantly male, hepatitis-B seropositive (94%) and cirrhotic (93%). Tokyo patients were older and more likely to have hepatitis-C (67%), smaller tumors, low albumin, and normal alpha-fetoprotein. The Honolulu cohort had the largest tumors and 30% had no viral hepatitis. Age-adjusted mortality at 1 and 5-years were lower in the Tokyo cohort compared to Honolulu and there was no difference in mortality between Shanghai and Honolulu cohorts. Elevated alpha-fetoprotein, low albumin and tumor > 5 cm were associated with increased 1-year mortality. These factors and cirrhosis were independently associated with increased 5-year mortality. Independent risk factors of survival varied when examined separately by center. CONCLUSIONThe profile of early-stage HCC patients is strikingly different across countries and likely contributes to survival differences. Underlying differences in patient populations including risk factors/comorbidities influencing disease progression may also account for variation in outcomes.展开更多

METHODS A systematic literature search was performed using PubM ed. Participants of any age and sex, who underwent liver transplantation for HCC were considered following these criteria:(1) studies comparing pre-transplant low vs high PLR values;(2) studies reporting post-transplant recurrence rates; and(3) if more than one study was reported by the same institute, only the most recent was included. The primary outcome measure was set for HCC recurrence after transplantation. RESULTS A total of 5 articles, published between 2014 and 2017, fulfilled the selection criteria. As for the quality of the reported studies, all the investigated articles presented an overall high quality. A total of 899 cases were investigated: 718 cases(80.0%) were males. Three studies coming from European countries and one from Japan presented HCV as the main cause of cirrhosis. On the opposite, one Chinese study presented a greater incidence of HBV-related cirrhotic cases. In all the studies apart one, the PLR cut-off value of 150 was reported. At meta-analysis, high PLR value was associated with a significant increase in recurrence after transplantation(OR = 3.33; 95%CI: 1.78-6.25; P < 0.001). A moderate heterogeneity was observed among the identified studies according to the Higgins I^2 statistic value.CONCLUSION Pre-transplant high PLR values are connected with an increased risk of post-operative recurrence of hepatocellular cancer. More studies are needed for better clarify the biological mechanisms of this results.展开更多

HCC predominantly occurs in the setting of liver cirrhosis and is a paradigm for inflammation-induced cancer. The causes of chronic liver disease promote the development of transformed or premalignant hepatocytes and predisposes to the development of HCC. For HCC to grow and progress it is now clear that it requires an immunosuppressive niche within the fibrogenic microenvironment of cirrhosis. The rationale for targeting this immunosuppression is supported by responses seen in recent trials with checkpoint inhibitors. With the impact of immunotherapy, HCC progression may be delayed and long term durable responses may be seen. This makes the management of the underlying liver cirrhosis in HCC even more crucial as studies demonstrate that measures of liver function are a major prognostic factor in HCC. In this review, we discuss the development of cancer in the setting of liver inflammation and fibrosis, reviewing the microenvironment that leads to this tumourigenic climate and the implications this has for patient management.展开更多

METHODS: We divided 45 patients into cryo-immunotherapy (21 patients), cryotherapy (n = 12), immunotherapy (n = 5) and untreated (n = 7) groups. Overall survival (OS) after diagnosis of metastatic hepatocellular cancer was assessed after an 8-year follow-up. RESULTS: Median OS was higher following cryo-immu-notherapy (32 mo) or cryotherapy (17.5 mo; P < 0.05) than in the untreated group (3 mo) and was higher in the cryo-immunotherapy group than in the cryotherapy group (P < 0.05). In the cryo-immunotherapy group, median OS was higher after multiple treatments (36.5 mo) than after a single treatment (21 mo; P < 0.05). CONCLUSION: Cryotherapy and, especially, cryoimmunotherapy significantly increased OS in metastatic hepatocellular cancer patients. Multiple cryo-immunotherapy was associated with a better prognosis than single cryo-immunotherapy.展开更多

METHODS Twelve tag SNPs covering the three onco-lnc RNAs were genotyped by the KASP method in a total of 1338 samples,including 521 HCC patients and frequencymatched 817 controls. The samples were obtained from an unrelated Chinese population at the First Hospital ofChina Medical University from 2012-2015. The expression quantitative trait loci(e QTL) analyses were conducted to explore further the potential function of the promising SNPs. RESULTS Three SNPs in HOTTIP,one promoter SNP in MALAT1,and one haplotype of HOTTIP were associated with HCC risk. The HOTTIP rs17501292,rs2067087,and rs17427960 SNPs were increased to 1.55-,1.20-,and 1.18-fold HCC risk under allelic models(P = 0.012,0.017 and 0.049,respectively). MALAT1 rs4102217 SNP was increased to a 1.32-fold HCC risk under dominant models(P = 0.028). In addition,the two-way interaction of HOTTIP rs17501292-MALAT1 rs619586 polymorphisms showed a decreased effect on HCC risk(P interaction = 0.028,OR = 0.30) and epistasis with each other. HOTTIP rs3807598 variant genotype showed significantly longer survival time in HBV negative subgroup(P = 0.049,HR = 0.12),and MALAT1 rs591291 showed significantly better prognosis in female and HBV negative subgroups(P = 0.022,HR = 0.37; P = 0.042,HR = 0.25,respectively). In the study,no significant effect was observed in e QTL analysis. CONCLUSION Specific lnc RNA(HOTTIP and MALAT1) SNPs have potential to be biomarkers for HCC risk and prognosis.展开更多

Material and Methods: Twenty-three consecutive patients with HCC diagnosed clinically or pathologically underwent C11-Acetate (C11-A) and F18-FDG (FDG) PET/CT imaging before surgery during a 424-day interval. After exclusion of treated or calcified lesions, 44 lesions are included in this study. The original metrics are the maximum SUV (SUVmax) and maximum or average HU (HUmax or HUmean) for lesions and normal liver. For the normal liver, an average SUV (SUVmean) was included. The derived values are the ratios of SUV/HU values. The efficacy is the fraction of outcomes of non-overlapping metrics between lesion and normal liver. Results: For FDG the efficacy is 0.489 for the lesions SUVmax versus normal liver SUVmax. For lesion SUVmax/HUmean versus normal liver SUVmax/HUmax, the efficacy is 1.00. For C11-A the corresponding values are 0.045 and 0.920. Conclusion: Normalizing SUV values for changes in HU values increases the contrast between normal liver and lesions. Analytical fusion can be very effective.展开更多

Advanced HCC displays strong resistance to chemotherapy, and traditional chemotherapy drugs do not achieve satisfactory therapeutic efficacy. The delivery of therapeutic compounds to the target site is a major challenge in the treatment of many diseases. Objective: This study aims to evaluate activated charcoal nanoparticles as a drug delivery system for anticancer agents (Sorafenib and Doxorubicin) in Hepatocellular Cancer Stem Cells. Method: The percent efficiency of entrapment (% EE) of the doxorubicin and sorafenib entrapped onto the activated charcoal was obtained by determining the free doxorubicin and sorafenib concentration in the supernatant-prepared solutions. Then the characterizations of nanoparticles were formed by determination of the particle size distribution, zeta potential, and polydispersity index (PDI). The anticancer activity of activated Charcoal, Doxorubicin-ACNP, sorafenib-ACNP, free doxorubicin, and free sorafenib solutions was measured based on cell viability percentage in HepG2 cell lines (ATCC-CCL 75). In vitro RBC’s toxicity of Doxorubicin/sorafenib loaded charcoal was estimated by hemolysis percentage. Results: The synthesized Doxorubicin-ACNP and Sorafenib-ACNP were evaluated and their physiochemical properties were also examined. Essentially, the percent Efficiency of Entrapment (EE %) was found to be 87.5% and 82.66% for Doxorubicin-ACNP and Sorafenib-ACNP, respectively. The loading capacity was 34.78% and 24.31% for Doxorubicin-ACNP and Sorafenib-ACNP. Using the Dynamic Light scattering [DLS] for the determination of the hydrodynamic size and surface zeta potential, a narrow sample size distribution was obtained of (18, 68, and 190 nm for charcoal, 105, 255, and 712 nm for doxorubicin, and 91, 295, and 955 nm for sorafenib), respectively. A surface charge of −13.2, −15.6 and −17 was obtained for charcoal, doxorubicin/charcoal, and sorafenib/charcoal nanoparticles. The cytotoxic activity of Doxorubicin-ACNP and Sorafenib-ACNP was evaluated in-vitro against HepG2 cell lines and it was observed that Drug loaded ACNP improved anticancer activity when compared to Doxorubicin or Sorafenib alone. Moreover, testing the toxicity potential of DOX-ACNP and Sorafenib-ACNP showed a significant reduction in the hemolysis of red blood cells when compared to Doxorubicin and Sorafenib alone. Conclusion: In conclusion, it is notable to state that this study is regarded as the first to investigate the use of Activated charcoal for the loading of Doxorubicin and Sorafenib for further use in the arena of hepatocellular carcinoma. Doxorubicin-ACNP and Sorafenib-ACNP showed noteworthy anticancer activity along with a reduced potential of RBCs hemolysis rendering it as an efficacious carrier with a low toxicity potential.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

It can mislead the physicians when the patient presents in an atypical way. Case Presentation: In this case report, we describe a fortuitous rupture of hepatocellular carcinoma in a 58-year-old male who was not previously diagnosed as having HCC and who came with atypical symptoms and signs of hemoperitoneum. He was then treated by trans-arterial embolectomy. Discussion: Diagnosis of hemoperitoneum in a case with bradycardia and hypotension is uncommon, as it goes more towards cardiogenic shock than hypovolemic shock, especially in a patient who is previously not symptomatic and has no risk factor for hepatocellular carcinoma. Conclusion: physicians should be alert to the possibility of encountering a hemorrhagic shock, although no trauma injury in any hypotensive patient with no clear reason for his condition.展开更多

Systemic treatments for HCC, particularly for advanced stages, are limited by the drug resistance phenomenon which ultimately leads to therapy failure. Recent studies have indicated an association between drug resistance and the existence of the cancer stem cells (CSCs) as tumor initiating cells. The CSCs are resistant to conventional chemotherapies and might be related to the mechanisms of the ATP Binding Cassette (ABC) transporters and alterations in the CSCs signaling pathways. Therefore, to contribute to the development of new HCC treatments, further information on the characterization of CSCs, the modulation of the ABC transporters expression and function and the signaling pathway involved in the self renewal, initiation and maintenance of the cancer are required. The combination of transporters modulators/inhibitors with molecular targeted therapies may be a potent strategy to block the tumoral progression. This review summarizes the association of CSCs, drug resistance, ABC transporters activities and changes in signaling pathways as a guide for future molecular therapy for HCC.展开更多
文摘Liver hepatocellular cancer(LIHC)is positioned as the third cancer with the highest mortalities worldwide,and high mortalities are associated with late diagnosis and recurrence.This study advances bioinformatics analysis of FAM3A expression in LIHC to evaluate its potential as a prognostic,diagnostic and therapeutic biomarker.Bioinformatics tools such as UALCAN,GEPIA2,KM plotter,TIMER2 and cBioPortal are employed to conduct analysis.Initially,the expression analysis revealed up-regulation of FAM3A in LIHC based on various variables.Further,the study observed that FAM3A methylation regulates expression as variation in methylation level of FAM3A was assessed in LIHC.Moreover,this over-expression of FAM3A results in poor overall survival(OS)in LIHC patients.All of these proposed that FAM3A has a role in the progression and development of LIHC.While examined association of FAM3A expression and infiltration level of CD8+T cells in LIHC patients using TIMER2 revealed that FAM3A has a positive correlation with purity in LIHC that highlights the molecular landscape.Analysis of genetic alteration revealed minute role of FAM3A in LIHC still provides valuable insight.Overall,our findings reveal that FAM3A has potential as diagnostic,therapeutic and prognostic biomarkers in LIHC.
文摘Growth factors and their corresponding receptors are commonly overexpressed and/or dysregulated in many cancers including hepatocellular cancer （HCC）. Clinical trials indicate that growth factor receptors and their related signalling pathways play important roles in HCC cancer etiology and progression, thus providing rational targets for innovative cancer therapies. A number of strategies including monoclonal antibodies, tyrosine kinase inhibitors （＂small molecule inhibitors＂） and antisense oligonucleotides have already been evaluated for their potency to inhibit the activity and downstream signalling cascades of these receptors in HCC. First clinical trials have also shown that multi-kinase inhibition is an effective novel treatment strategy in HCC. In this respect sorafenib, an inhibitor of Raf-, VEGF- and PDGF-signalling, is the first multi-kinase inhibitor that has been approved by the FDA for the treatment of advanced HCC. Moreover, the serine-threonine kinase of mammalian target of rapamycin （mTOR） upon which the signalling of several growth factor receptors converge plays a central role in cancer cell proliferation, roTOR inhibition of HCC is currently also being studied in preclinical trials. As HCCs represent hypervascularized neoplasms, inhibition of tumour vessel formation via interfering with the VEGF/VEGFR system is another promising approach in HCC treatment. This review will summarize the current status of the various growth factor receptor-based treatment strategies and in view of the multitude of novel targeted approaches, the rationale for combination therapies for advanced HCC treatment will also be taken into account.
文摘AIM: To estimate if and to what extent long acting octreotide (LAR) improves survival and quality of life in patients with advanced hepatocellular carcinoma (HCC). METHODS: A total of 127 cirrhotics, stages A-B, due to chronic viral infections and with advanced HCC, were enrolled in the study. Scintigraphy with 111Indium labeled octreotide was performed in all cases. The patients with increased accumulation of radionuclear compound were randomized to receive either oral placebo only or octreotide/octreotide LAR only as follows: octreotide 0.5mg s.c. every 8 h for 6 wk, at the end of wk 4-8 octreotide LAR 20 mg i.m. and at the end of wk 12 and every 4 wk octreotide LAR 30mg i.m.. Follow-up was worked out monthly as well as the estimation of quality of life (QLQ-C30 questionnaire). Patients with negative somatostatin receptors (SSTR) detection were followed up in the same manner. RESULTS: Scintigraphy demonstrated SSTR in 61 patients. Thirty were randomized to receive only placebo and 31 only octreotide. A significantly higher survival time was observed for the octreotide group (49 ± 6 wk) as compared to the control group (28 ± 1 wk) and to the SSTR negative group (28 ± 2 wk), LR = 20.39, df = 2, P < 0.01. The octreotide group presented 68.5% lower hazard ratio [95% CI (47.4%-81.2%)]. During the f irst year, a 22%, 39% and 43% decrease in the QLQ-C30 score was observed in each group respectively.CONCLUSION: The proposed therapeutic approach has shown to improve the survival and quality of life in SSTR positive patients with advanced HCC.
文摘BACKGROUND Prediction of survival after the treatment of hepatocellular carcinoma(HCC)has been widely investigated,yet remains inadequate.The application of artificial intelligence(AI)is emerging as a valid adjunct to traditional statistics due to the ability to process vast amounts of data and find hidden interconnections between variables.AI and deep learning are increasingly employed in several topics of liver cancer research,including diagnosis,pathology,and prognosis.AIM To assess the role of AI in the prediction of survival following HCC treatment.METHODS A web-based literature search was performed according to the Preferred Reporting Items for Systemic Reviews and Meta-Analysis guidelines using the keywords“artificial intelligence”,“deep learning”and“hepatocellular carcinoma”(and synonyms).The specific research question was formulated following the patient(patients with HCC),intervention(evaluation of HCC treatment using AI),comparison(evaluation without using AI),and outcome(patient death and/or tumor recurrence)structure.English language articles were retrieved,screened,and reviewed by the authors.The quality of the papers was assessed using the Risk of Bias In Non-randomized Studies of Interventions tool.Data were extracted and collected in a database.RESULTS Among the 598 articles screened,nine papers met the inclusion criteria,six of which had low-risk rates of bias.Eight articles were published in the last decade;all came from eastern countries.Patient sample size was extremely heterogenous(n=11-22926).AI methodologies employed included artificial neural networks(ANN)in six studies,as well as support vector machine,artificial plant optimization,and peritumoral radiomics in the remaining three studies.All the studies testing the role of ANN compared the performance of ANN with traditional statistics.Training cohorts were used to train the neural networks that were then applied to validation cohorts.In all cases,the AI models demonstrated superior predictive performance compared with traditional statistics with significantly improved areas under the curve.CONCLUSION AI applied to survival prediction after HCC treatment provided enhanced accuracy compared with conventional linear systems of analysis.Improved transferability and reproducibility will facilitate the widespread use of AI methodologies.
文摘AIMTo compare patients who underwent resection of early stage hepatocellular cancer (HCC) in three different countries. METHODSThis retrospective study characterizes 573 stage I/II HCC patients treated with liver resection in 3 tertiary-referral centers: Tokyo (n = 250), Honolulu (n = 146) and Shanghai (n = 177). RESULTSShanghai patients were younger, predominantly male, hepatitis-B seropositive (94%) and cirrhotic (93%). Tokyo patients were older and more likely to have hepatitis-C (67%), smaller tumors, low albumin, and normal alpha-fetoprotein. The Honolulu cohort had the largest tumors and 30% had no viral hepatitis. Age-adjusted mortality at 1 and 5-years were lower in the Tokyo cohort compared to Honolulu and there was no difference in mortality between Shanghai and Honolulu cohorts. Elevated alpha-fetoprotein, low albumin and tumor > 5 cm were associated with increased 1-year mortality. These factors and cirrhosis were independently associated with increased 5-year mortality. Independent risk factors of survival varied when examined separately by center. CONCLUSIONThe profile of early-stage HCC patients is strikingly different across countries and likely contributes to survival differences. Underlying differences in patient populations including risk factors/comorbidities influencing disease progression may also account for variation in outcomes.
文摘AIM To perform a systematic review and meta-analysis on platelet-to-lymphocyte ratio(PLR) as a risk factor for post-transplant hepatocellular cancer(HCC) recurrence. METHODS A systematic literature search was performed using PubM ed. Participants of any age and sex, who underwent liver transplantation for HCC were considered following these criteria:(1) studies comparing pre-transplant low vs high PLR values;(2) studies reporting post-transplant recurrence rates; and(3) if more than one study was reported by the same institute, only the most recent was included. The primary outcome measure was set for HCC recurrence after transplantation. RESULTS A total of 5 articles, published between 2014 and 2017, fulfilled the selection criteria. As for the quality of the reported studies, all the investigated articles presented an overall high quality. A total of 899 cases were investigated: 718 cases(80.0%) were males. Three studies coming from European countries and one from Japan presented HCV as the main cause of cirrhosis. On the opposite, one Chinese study presented a greater incidence of HBV-related cirrhotic cases. In all the studies apart one, the PLR cut-off value of 150 was reported. At meta-analysis, high PLR value was associated with a significant increase in recurrence after transplantation(OR = 3.33; 95%CI: 1.78-6.25; P < 0.001). A moderate heterogeneity was observed among the identified studies according to the Higgins I^2 statistic value.CONCLUSION Pre-transplant high PLR values are connected with an increased risk of post-operative recurrence of hepatocellular cancer. More studies are needed for better clarify the biological mechanisms of this results.
文摘Hepatocellular carcinoma(HCC) is now the second leading cause of cancer-related deaths globally and many patients have incurable disease. HCC predominantly occurs in the setting of liver cirrhosis and is a paradigm for inflammation-induced cancer. The causes of chronic liver disease promote the development of transformed or premalignant hepatocytes and predisposes to the development of HCC. For HCC to grow and progress it is now clear that it requires an immunosuppressive niche within the fibrogenic microenvironment of cirrhosis. The rationale for targeting this immunosuppression is supported by responses seen in recent trials with checkpoint inhibitors. With the impact of immunotherapy, HCC progression may be delayed and long term durable responses may be seen. This makes the management of the underlying liver cirrhosis in HCC even more crucial as studies demonstrate that measures of liver function are a major prognostic factor in HCC. In this review, we discuss the development of cancer in the setting of liver inflammation and fibrosis, reviewing the microenvironment that leads to this tumourigenic climate and the implications this has for patient management.
文摘AIM: To retrospectively assess the effect of comprehensive cryosurgery (ablation of intraand extra-hepatic tumors) plus dendritic cell-cytokine-induced killer cell immunotherapy in metastatic hepatocellular cancer. METHODS: We divided 45 patients into cryo-immunotherapy (21 patients), cryotherapy (n = 12), immunotherapy (n = 5) and untreated (n = 7) groups. Overall survival (OS) after diagnosis of metastatic hepatocellular cancer was assessed after an 8-year follow-up. RESULTS: Median OS was higher following cryo-immu-notherapy (32 mo) or cryotherapy (17.5 mo; P < 0.05) than in the untreated group (3 mo) and was higher in the cryo-immunotherapy group than in the cryotherapy group (P < 0.05). In the cryo-immunotherapy group, median OS was higher after multiple treatments (36.5 mo) than after a single treatment (21 mo; P < 0.05). CONCLUSION: Cryotherapy and, especially, cryoimmunotherapy significantly increased OS in metastatic hepatocellular cancer patients. Multiple cryo-immunotherapy was associated with a better prognosis than single cryo-immunotherapy.

文摘AIM To evaluate the association of 12 tag single nucleotide polymorphisms(tag SNPs) in three onco-long non-coding RNA(lnc RNA) genes(HOTTIP,CCAT2,MALAT1) with the risk and prognosis of hepatocellular cancer(HCC). METHODS Twelve tag SNPs covering the three onco-lnc RNAs were genotyped by the KASP method in a total of 1338 samples,including 521 HCC patients and frequencymatched 817 controls. The samples were obtained from an unrelated Chinese population at the First Hospital ofChina Medical University from 2012-2015. The expression quantitative trait loci(e QTL) analyses were conducted to explore further the potential function of the promising SNPs. RESULTS Three SNPs in HOTTIP,one promoter SNP in MALAT1,and one haplotype of HOTTIP were associated with HCC risk. The HOTTIP rs17501292,rs2067087,and rs17427960 SNPs were increased to 1.55-,1.20-,and 1.18-fold HCC risk under allelic models(P = 0.012,0.017 and 0.049,respectively). MALAT1 rs4102217 SNP was increased to a 1.32-fold HCC risk under dominant models(P = 0.028). In addition,the two-way interaction of HOTTIP rs17501292-MALAT1 rs619586 polymorphisms showed a decreased effect on HCC risk(P interaction = 0.028,OR = 0.30) and epistasis with each other. HOTTIP rs3807598 variant genotype showed significantly longer survival time in HBV negative subgroup(P = 0.049,HR = 0.12),and MALAT1 rs591291 showed significantly better prognosis in female and HBV negative subgroups(P = 0.022,HR = 0.37; P = 0.042,HR = 0.25,respectively). In the study,no significant effect was observed in e QTL analysis. CONCLUSION Specific lnc RNA(HOTTIP and MALAT1) SNPs have potential to be biomarkers for HCC risk and prognosis.
文摘Purpose: Since HCC lesions are generally characterized by lower Hounsfield unit value (HU) values and higher tracer uptake (SUV or Standardized Uptake Values), we intended to determine if normalizing the SUV by the HU, for the lesion and normal liver would improve sensitivity and specificity. Material and Methods: Twenty-three consecutive patients with HCC diagnosed clinically or pathologically underwent C11-Acetate (C11-A) and F18-FDG (FDG) PET/CT imaging before surgery during a 424-day interval. After exclusion of treated or calcified lesions, 44 lesions are included in this study. The original metrics are the maximum SUV (SUVmax) and maximum or average HU (HUmax or HUmean) for lesions and normal liver. For the normal liver, an average SUV (SUVmean) was included. The derived values are the ratios of SUV/HU values. The efficacy is the fraction of outcomes of non-overlapping metrics between lesion and normal liver. Results: For FDG the efficacy is 0.489 for the lesions SUVmax versus normal liver SUVmax. For lesion SUVmax/HUmean versus normal liver SUVmax/HUmax, the efficacy is 1.00. For C11-A the corresponding values are 0.045 and 0.920. Conclusion: Normalizing SUV values for changes in HU values increases the contrast between normal liver and lesions. Analytical fusion can be very effective.
文摘Hepatocellular carcinoma(HCC)is a disease of public health concern in Nigeria,with chronic hepatitis B and C infections contributing most to the disease burden.Despite the increasing incidence of HCC,surveillance practices for early diagnosis and possible cure are not deeply rooted in the country.This article aims to review the current status of HCC surveillance in Nigeria,stressing the encounters,breaches,and potential prospects.Several factors,such as limited tools for screening and diagnostics,insufficient infrastructure,and low cognizance among the doctors,and the general public affect the surveillance practices for HCC in Nigeria.Moreover,the lack of standardized guidelines and protocols for HCC surveillance further intensifies the suboptimal diagnosis and treatment.Nevertheless,there are opportunities for refining surveillance practices in the country.This would be achieved through boosted public health sensitization campaigns,integrating HCC screening into routine clinical services,and leveraging technological developments for early detection and monitoring.Furthermore,collaboration between government agencies,healthcare providers,and international organizations can facilitate the development of comprehensive HCC surveillance programs person-alized to the Nigerian setting.Thus,HCC surveillance practice faces substantial challenges.By addressing the drawbacks and leveraging prospects,Nigeria can improve HCC surveillance,with subsequent improved outcomes for individuals at risk of developing the disease.
文摘Background: Hepatocellular carcinoma (HCC) is the most common type of liver cancer and one of the leading causes of cancer-related death worldwide. Advanced HCC displays strong resistance to chemotherapy, and traditional chemotherapy drugs do not achieve satisfactory therapeutic efficacy. The delivery of therapeutic compounds to the target site is a major challenge in the treatment of many diseases. Objective: This study aims to evaluate activated charcoal nanoparticles as a drug delivery system for anticancer agents (Sorafenib and Doxorubicin) in Hepatocellular Cancer Stem Cells. Method: The percent efficiency of entrapment (% EE) of the doxorubicin and sorafenib entrapped onto the activated charcoal was obtained by determining the free doxorubicin and sorafenib concentration in the supernatant-prepared solutions. Then the characterizations of nanoparticles were formed by determination of the particle size distribution, zeta potential, and polydispersity index (PDI). The anticancer activity of activated Charcoal, Doxorubicin-ACNP, sorafenib-ACNP, free doxorubicin, and free sorafenib solutions was measured based on cell viability percentage in HepG2 cell lines (ATCC-CCL 75). In vitro RBC’s toxicity of Doxorubicin/sorafenib loaded charcoal was estimated by hemolysis percentage. Results: The synthesized Doxorubicin-ACNP and Sorafenib-ACNP were evaluated and their physiochemical properties were also examined. Essentially, the percent Efficiency of Entrapment (EE %) was found to be 87.5% and 82.66% for Doxorubicin-ACNP and Sorafenib-ACNP, respectively. The loading capacity was 34.78% and 24.31% for Doxorubicin-ACNP and Sorafenib-ACNP. Using the Dynamic Light scattering [DLS] for the determination of the hydrodynamic size and surface zeta potential, a narrow sample size distribution was obtained of (18, 68, and 190 nm for charcoal, 105, 255, and 712 nm for doxorubicin, and 91, 295, and 955 nm for sorafenib), respectively. A surface charge of −13.2, −15.6 and −17 was obtained for charcoal, doxorubicin/charcoal, and sorafenib/charcoal nanoparticles. The cytotoxic activity of Doxorubicin-ACNP and Sorafenib-ACNP was evaluated in-vitro against HepG2 cell lines and it was observed that Drug loaded ACNP improved anticancer activity when compared to Doxorubicin or Sorafenib alone. Moreover, testing the toxicity potential of DOX-ACNP and Sorafenib-ACNP showed a significant reduction in the hemolysis of red blood cells when compared to Doxorubicin and Sorafenib alone. Conclusion: In conclusion, it is notable to state that this study is regarded as the first to investigate the use of Activated charcoal for the loading of Doxorubicin and Sorafenib for further use in the arena of hepatocellular carcinoma. Doxorubicin-ACNP and Sorafenib-ACNP showed noteworthy anticancer activity along with a reduced potential of RBCs hemolysis rendering it as an efficacious carrier with a low toxicity potential.
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Objective：To study the inhibitory effect of Fuzheng Yiliu Granule（扶正抑瘤颗粒,FYG） on hepatocellular cancer（HCC） and investigate the mechanism mediating its bioactivity.Methods：H22 tumor-bearing ICR mice were treated with FYG[3.6 g/（kg·d）]for 5 days.Tumor volume and tumor weight,percentages of CD3~＋,CD4~＋,CD8~＋,and natural killer（NK） cells in peripheral blood,tumor apoptosis and serum levels of interleukin-2（IL-2）,and tumor necrosis factor-α（TNF-α） were evaluated.FYG-containing serum was prepared from SD rats treated for 7 days[high dose 3.6 g/（kg·d）;middle dose 1.8 g/（kg·d）;low dose 0.9 g/（kg·d）].Cell cycle,cell viability,and apoptosis were evaluated after HepG2 cell line was cultured in FYG-containing serum for 48 h.The levels of IL-2 and TNF-αin FYG-containing serum were also determined.Results：FYG produced a potent antitumor effect（P0.01） and induced marked apoptosis of the tumor tissue（P0.05）.Mice treated with FYG had higher percentages of CD3~＋ and CD4~＋（P0.05）,and more NK cells（P0.01） in the peripheral blood than those in the animals treated with normal saline.Mice receiving FYG had the highest serum levels of IL-2 and TNF-α（P0.01）.High-dose FYG-containing serum significantly decreased HepG2 cell viability,inhibited cell proliferation（P0.05）,and induced apoptosis（P0.01）.In addition,the levels of IL-2 and TNF-αof highdose -containing serum were higher than the blank serum（P0.01）.Conclusion：FYG could inhibit HCC growth by regulating immune function and inducing apoptosis of tumor cells in vivo and in vitro.
文摘Introduction: Acute hemoperitoneum due to the spontaneous rupture of hepatocellular carcinoma (HCC) is a rare case of non-traumatic intra-abdomen bleeding that requires a high index of suspicion to approach, especially if no known history of HCC. It can mislead the physicians when the patient presents in an atypical way. Case Presentation: In this case report, we describe a fortuitous rupture of hepatocellular carcinoma in a 58-year-old male who was not previously diagnosed as having HCC and who came with atypical symptoms and signs of hemoperitoneum. He was then treated by trans-arterial embolectomy. Discussion: Diagnosis of hemoperitoneum in a case with bradycardia and hypotension is uncommon, as it goes more towards cardiogenic shock than hypovolemic shock, especially in a patient who is previously not symptomatic and has no risk factor for hepatocellular carcinoma. Conclusion: physicians should be alert to the possibility of encountering a hemorrhagic shock, although no trauma injury in any hypotensive patient with no clear reason for his condition.
文摘Aim:Long-term survival after hepatocellular cancer(HCC)is difficult to achieve likely related to recurrence.This study aimed to identify factors that were predictive of 10-year survival after the diagnosis of HCC.Methods:In a prospectively collected database of 1374 HCC cases(1993-2019),we identified 70 patients who survived over 10 years regardless of treatment.We then identified 164 patients in the entire cohort who either had liver resection or transplant,and died before 10 years.Demographics,tumor characteristics,treatment,recurrence and treatment of recurrence were compared.Results:Of the 10-year survivors,36 underwent transplant,27 had liver resection and 7 patients had only locoregional therapy.Compared to the non-survivors,the 10-year survivors were younger and had fewer comorbidities or recurrence,smaller tumor size,lower AST,ALT,AFP,platelets,neutrophil-to-lymphocyte ratio.Multivariate analysis showed only age and diabetes to be negative predictors.Recurrence occurred in 24 survivors(34.3%)with mean time to recurrence with standard deviation 57.1±42.6 months compared to 80 non-survivors(48.7%)with mean time to recurrence of 15.3±14.8 months.For hepatic resection,10-year survivors had longer time to recurrence compared to non-survivors(median:31.3 months).Conclusion:Long-term survivors mostly occur after resection or transplant,but 10%of our cohort survived 10 years with only locoregional therapy.Underlying health status maybe an important predictor of 10-year survival for ;patients receiving liver resections.Recurrence of HCC occurs in both 10-year survivors and non-survivors,but later recurrence with aggressive treatment of the recurrence may allow for 10-year survival.

文摘Non-coding RNAs are speculated to exert important regulatory functions at the level of gene expression,oncogenesis,and many other pathologies.Hepatitis B virus(HBV)infection is a leading cause of hepatocellular carcinoma(HCC),and some studies have shown that the expression of non-coding RNAs has an assignable effect on the development of HBV-induced HCC.In this context,the functions and molecular mechanisms of the HBVinduced non-coding RNA expression in the development of hepatoma have attracted increasing attention.This review covers the progress in the exploration of the relationship between HBV-induced hepatoma and non-coding RNA expression,cataloging the recent reports about the roles of non-coding RNAs in HBV-induced hepatoma into five classes,including(1)modulation of metabolism in hepatic cancer,(2)aggravation of inflammation and hepatic fibrosis,(3)alteration of the tumor immune microenvironment,(4)non-coding RNA N6-methyladenosine modification,and a seemingly opposite process,(5)the suppression of the progression of HBV-related HCC.All evidence supports non-coding RNAs as promising novel targets for the early diagnosis and treatments for HCC.

文摘Hepatocellular carcinoma (HCC) is one of most common malignancies in the world. Systemic treatments for HCC, particularly for advanced stages, are limited by the drug resistance phenomenon which ultimately leads to therapy failure. Recent studies have indicated an association between drug resistance and the existence of the cancer stem cells (CSCs) as tumor initiating cells. The CSCs are resistant to conventional chemotherapies and might be related to the mechanisms of the ATP Binding Cassette (ABC) transporters and alterations in the CSCs signaling pathways. Therefore, to contribute to the development of new HCC treatments, further information on the characterization of CSCs, the modulation of the ABC transporters expression and function and the signaling pathway involved in the self renewal, initiation and maintenance of the cancer are required. The combination of transporters modulators/inhibitors with molecular targeted therapies may be a potent strategy to block the tumoral progression. This review summarizes the association of CSCs, drug resistance, ABC transporters activities and changes in signaling pathways as a guide for future molecular therapy for HCC.
