BACKGROUND Alpha-fetoprotein(AFP),a commonly used biomarker for hepatocellular carcinoma(HCC),is normal in up to one-third of patients.AIM To evaluate the diagnostic performance of des-gamma-carboxy-prothrombin(DCP)alone and in combination with AFP.METHODS In this study,202 patients with radiologically proven HCC were enrolled,and their DCP and AFP levels were evaluated for their diagnostic performance.RESULTS The mean age of the enrolled patients was 58.5 years;72.0%were male.DCP was elevated in 86.6%(n=175)of all patients,100.0%(n=74)of patients with portal vein thrombus,and 87.4%(n=111)of patients with multicentric HCC.AFP was elevated in 64.3%(n=130)of all the patients,74%(n=55)of the patients with portal vein thrombus,and 71.6%(n=91)of the patients with multicentric HCC(P=0.030,0.001,and 0.015,respectively).In tumors less than 2 cm in size(n=46),DCP was increased in 32(69.5%)patients,and AFP was increased in 25(54.3%)patients(P=0.801).There was good pairing between DCP and AFP for HCCs of 2 cm size or larger(P<0.001);however,the pairing among tumors<2 cm size was not significant(P=0.210).In 69 of the patients(34.1%),only one of the tumor markers was positive;DCP was elevated alone in 57/202(28.2%)of all patients,and AFP alone was elevated in 12/202(5.9%)of the patients.The areas under receiver operating characteristic curves(AUROC)for tumors>2 cm was 0.74 for DCP and 0.59 for AFP;combining both markers resulted in an AUROC of 0.73.For tumors<2 cm,the AUROC was 0.25 for DCP and 0.40 for AFP.CONCLUSION DCP,as an individual marker,had a better diagnostic performance in many cases of HCC.Hence,DCP may replace AFP as the primary HCC biomarker. 展开更多

BACKGROUND Sarcopenia may be associated with hepatocellular carcinoma(HCC)following hepatectomy.But traditional single clinical variables are still insufficient to predict recurrence.We still lack effective prediction models for recent recurrence(time to recurrence<2 years)after hepatectomy for HCC.AIM To establish an interventable prediction model to estimate recurrence-free survival(RFS)after hepatectomy for HCC based on sarcopenia.METHODS We retrospectively analyzed 283 hepatitis B-related HCC patients who underwent curative hepatectomy for the first time,and the skeletal muscle index at the third lumbar spine was measured by preoperative computed tomography.94 of these patients were enrolled for external validation.Cox multivariate analysis was per-formed to identify the risk factors of postoperative recurrence in training cohort.A nomogram model was developed to predict the RFS of HCC patients,and its predictive performance was validated.The predictive efficacy of this model was evaluated using the receiver operating characteristic curve.RESULTS Multivariate analysis showed that sarcopenia[Hazard ratio(HR)=1.767,95%CI:1.166-2.678,P<0.05],alpha-fetoprotein≥40 ng/mL(HR=1.984,95%CI:1.307-3.011,P<0.05),the maximum diameter of tumor>5 cm(HR=2.222,95%CI:1.285-3.842,P<0.05),and hepatitis B virus DNA level≥2000 IU/mL(HR=2.1,95%CI:1.407-3.135,P<0.05)were independent risk factors associated with postoperative recurrence of HCC.Based on the sarcopenia to assess the RFS model of hepatectomy with hepatitis B-related liver cancer disease(SAMD)was established combined with other the above risk factors.The area under the curve of the SAMD model was 0.782(95%CI:0.705-0.858)in the training cohort(sensitivity 81%,specificity 63%)and 0.773(95%CI:0.707-0.838)in the validation cohort.Besides,a SAMD score≥110 was better to distinguish the high-risk group of postoperative recurrence of HCC.CONCLUSION Sarcopenia is associated with recent recurrence after hepatectomy for hepatitis B-related HCC.A nutritional status-based prediction model is first established for postoperative recurrence of hepatitis B-related HCC,which is superior to other models and contributes to prognosis prediction. 展开更多

BACKGROUND The GALAD score has improved early hepatocellular carcinoma(HCC)detection rate.The role of the GALAD score in staging and predicting tumor characteristics or clinical outcome of HCC remains of particular interest.AIM To determine the diagnostic/prognostic performances of the GALAD score at various phases of initial diagnosis,tumor features,and 1-year mortality of HCC and compare the performance of the GALAD score with those of other serum biomarkers.METHODS This prospective,diagnostic/prognostic study was conducted among patients with newly diagnosed HCC at the liver center of Vajira Hospital.Eligible patients had HCC staging allocation using the Barcelona Clinic Liver Cancer(BCLC)categorization.Demographics,HCC etiology,and HCC features were recorded.Biomarkers and the GALAD score were obtained at baseline.The performance of the GALAD score and biomarkers were prospectively assessed.RESULTS Exactly 115 individuals were diagnosed with HCC.The GALAD score increased with disease severity.Between BCLC-0/A and BCLC-B/C/D,the GALAD score predicted HCC staging with an area under the curve(AUC)of 0.868(95%CI:0.80–0.93).For identifying the curative HCC,the AUC of GALAD score was significantly higher than that of Alpha-fetoprotein(AFP)(0.753)and Lens culinaris agglutinin-reactive fraction of AFP-L3(0.706),and as good as that of Protein induced by vitamin K absence-II(PIVKA-II)(0.897).For detecting aggressive features,the GALAD score gave an AUC of 0.839(95%CI:0.75–0.92)and significantly outperformed compared to that of AFP(0.761)and AFP-L3(0.697),with a trend of superiority to that of PIVKA-II(0.772).The performance to predict 1-year mortality of GALAD score(AUC:0.711,95%CI:0.60–0.82)was better than that of AFP(0.541)and as good as that of PIVKA-II(0.736).The optimal cutoff value of GALAD score was≥6.83,with a specificity of 72.63%for exhibiting substantial reduction in the 1-year mortality.CONCLUSION The GALAD model can diagnose HCC at the curative stage,including the characteristic of advanced disease,more than that by AFP and AFP-L3,but not PIVKA-II.The GALAD score can be used to predict the 1-year mortality of HCC. 展开更多

Objective Xiaoaiping (XAP) is a traditional Chinese medicine that is a commonly used as an anticancerdrug in clinical practice owing to its high efficiency and low toxicity. Specifically, XAP can effectively inhibitthe growth of hepatocellular carcinoma (HCC). Alpha-fetoprotein (AFP) is a key HCC diagnostic marker andis closely related to certain malignant cytological behaviors of HCC. However, whether AFP expression andXAP treatment are related to the invasion and metastasis of HCC remains unclear. In the present study, weaimed to evaluate the effects and underlying mechanism of XAP on the invasion and metastasis of HCC..Methods Using a cell scratch assay, Transwell technology, and western blotting we detected the differentinvasion and metastatic abilities of Hep3B cells in XAP treatment and blank control groups. This allowedcomparison of the invasion and metastatic abilities of Hep3B cells with differing levels of AFP expression.AFP mRNA sequencing technology was used to analyze the mechanism of tumor invasion and metastasisassociated with AFP and XAP treatment.Results Cell invasion and metastasis abilities in the XAP group were significantly lower than those in thecontrol group (P < 0.05). Additionally, compared to the control group, the expression of AFP significantlydecreased after XAP treatment (P < 0.05). The ability of Hep3B cells to invade and metastasize waspromoted when AFP expression was up-regulated, whereas it was inhibited when AFP was silenced. XAPinjection and AFP regulate the invasion and metastatic ability of HCC by affecting matrix metalloproteinases(MMPs).Conclusion XAP injection inhibits the invasion and metastatic ability of HCC by influencing the expressionof AFP;additionally, this inhibition of AFP is achieved by affecting MMPs. 展开更多

Hepatocellular carcinoma(HCC)is one of the world’s deadliest and fastestgrowing tumors,with a poor prognosis.HCC develops in the context of chronic liver disease.Curative resection,surgery(liver transplantation),trans-arterial chemoembolization,radioembolization,radiofrequency ablation and chemotherapy are common treatment options for HCC,however,they will only assist a limited percentage of patients.Current treatments for advanced HCC are ineffective and aggravate the underlying liver condition.Despite promising preclinical and early-phase clinical trials for some drugs,existing systemic therapeutic methods for advanced tumor stages remain limited,underlining an unmet clinical need.In current years,cancer immunotherapy has made significant progress,opening up new treatment options for HCC.HCC,on the other hand,has a variety of causes and can affects the body’s immune system via a variety of mechanisms.With the speedy advancement of synthetic biology and genetic engineering,a range of innovative immunotherapies,such as immune checkpoint inhibitors[anti-programmed cell death-1(PD-1),anti-cytotoxic T lymphocyte antigen-4,and anti-PD ligand 1 cell death antibodies],therapeutic cancer vaccines,engineered cytokines,and adoptive cell therapy have all been used for the treatment of advanced HCC.In this review,we summarize the present clinical and preclinical landscape of immunotherapies in HCC,critically discuss recent clinical trial outcomes,and address future perspectives in the field of liver cancer. 展开更多

BACKGROUND Hepatocellular carcinoma(HCC)is the most common type of primary liver cancer.With highly invasive biological characteristics and a lack of obvious clinical manifestations,HCC usually has a poor prognosis and ranks fourth in cancer mortality.The aetiology and exact molecular mechanism of primary HCC are still unclear.AIM To select the characteristic genes that are significantly associated with the prognosis of HCC patients and construct a prognosis model of this malignancy.METHODS By comparing the gene expression levels of patients with different cancer grades of HCC,we screened out differentially expressed genes associated with tumour grade.By protein-protein interaction(PPI)network analysis,we obtained the top 2 PPI networks and hub genes from these differentially expressed genes.By using least absolute shrinkage and selection operator Cox regression,13 prognostic genes were selected for feature extraction,and a prognostic risk model of HCC was established.RESULTS The model had significant prognostic ability in HCC.We also analysed the biological functions of these prognostic genes.CONCLUSION By comparing the gene profiles of patients with different stages of HCC,We have constructed a prognosis model consisting of 13 genes that have important prognostic value.This model has good application value and can be explained clinically. 展开更多

BACKGROUND: Hepatocellular carcinoma (HCC) is one of the most common malignant tumors worldwide, its prognosis is poor, and early detection is of utmost importance. Although alpha-fetoprotein (AFP) is a useful marker for detecting and monitoring HCC development, the false-negative or false-positive rates with AFP alone may be as high as 30%-40% for patients with small HCCs. To enhance the specificity and accuracy of AFP measurements for HCC, we analyzed AFP expression states in livers, detected the hepatoma-specific AFP (HS-AFP) fraction and AFP-mRNA from peripheral blood mononuclear cells, and explored their clinical implications for HCC diagnosis. METHODS: AFP expression and hepatocyte distributions in liver specimens were investigated by an immunohistoche- mical assay. Total RNAs were extracted from circulating blood, synthesized to cDNA through random primers and reverse transcriptase, and fragments of the AFP gene were amplified by a nested-PCR assay. The HS-AFP fraction was separated by lectin-affinity chromatography and its level was detected by radioimmunoassay. RESULTS: The incidence of AFP was 73.3% in HCC tissues and its expression in HCCs with moderate or low differentiation was significantly stronger than that of HCCs with high differentiation (P<0.05). The incidence of AFP gene fragments was 100% in HCCs, and 60% in paracancerous tissues (P<0.01). In the HCC and liver cirrhosis groups, the incidence of HS-AFP was 91.7% and 18% (P<0.01), and of AFP-mRNA was 56.7% and 16% (P<0.01), respectively, and neither was found in controls.HS-AFP or AFP-mRNA was not significantly related to size or number of HCC, but to its differentiation, metastasis, and relapse (P<0.05). CONCLUSIONS: Different AFP expression is present in different parts of HCC tissues. HS-AFP and AFP-mRNA fragments improve sensitivity and specificity, and both are useful markers to diagnose HCC or monitor metastasis and relapse. 展开更多

Alpha-fetoprotein(AFP)is an oncofetal glycoprotein that has been used as a tumor marker for hepatocellular carcinoma(HCC)in combination with ultrasound and other imaging modalities.Its utility is limited because of both low sensitivity and specificity,and discrepancies among the different methods of measurements.Moreover,its accuracy varies according to patient characteristics and the AFP cut-off values used.Combination of AFP with novel biomarkers such as AFP-L3,Golgi specific membrane protein(GP73)and des-gamma-carboxyprothrombin significantly improved its accuracy in detecting HCC.Increased AFP level could also signify severity of hepatic destruction and subsequent regeneration and is commonly observed in patients with acute and chronic liver conditions and cirrhosis.Hereditary and other non-hepatic disorders can also cause AFP elevation. 展开更多

The diagnoses were made by three radiologists em- ploying a 5-point rating scale, with postoperative pathologic results as the gold standard. Receiver operating characteristic (ROC) curve analysis was performed to evaluate the diag- nostic value of the three MSCT combination modes (arterial phase+portal-venous phase, arterial phase+delayed phase, arterial phase+portal-venous phase+delayed phase) and AFP levels for sHCC on the background of liver cirrhosis. RESULTS: The area under ROC curve (AUC), sensitivity, and specificity of the combination of arterial phase+portal- venous phase+delayed phase were 0.93, 93%, and 82%, respectively. The average AUC of the arterial phase+portal- venous phase+delayed phase combination was significantly greater than that of the arterial phase+portal-venous phase (AUC=0.84, P=0.01) and arterial phase+delayed phase (AUC=0.85, P=0.03). Arterial phase+portal-venous phase had a smaller AUC (0.84) than arterial phase+delayed phase (0.85), but the difference was insignificant (P=0.15). After combining MSCT enhancement scan with AFP, the AUC, sensitivity, and specificity were 0.95, 94%, and 83%, respectively, indicating a greatly increased diagnostic efficiency for sHCC. CONCLUSIONS: The combination of AFP and 3 phases MSCT enhancement scan could increase the diagnostic efficiency for sHCC on the background of liver cirrhosis. The application of ROC curve analysis has provided a new method and reference in HCC diagnosis. 展开更多

BACKGROUND Researchers have investigated the diagnostic value of protein induced by vitamin K absence or antagonist II (PIVKA-II) and alpha-fetoprotein (AFP) in hepatitis B virus (HBV)-related hepatocellular carcinoma (HCC), and obtained abundant clinical diagnostic data. However, PIVKA-II and AFP have unsatisfactory specificity and sensitivity in the diagnosis of early-stage HBV-related HCC. Gamma-glutamyltransferase (γ-GT) and aspartate aminotransferase (AST) are common biomarkers for evaluating liver function, and we hypothesized that the γ-GT/AST ratio in combination with PIVKA-II and AFP would improve the diagnosis of early-stage HBV-related HCC. AIM To evaluate the diagnostic value of γ-GT/AST ratio alone or in combination with PIVKA-II and AFP in HBV-related HCC. METHODS Serum levels of γ-GT, AST, PIVKA-II, and AFP were detected and analysed in 176 patients with HBV-related HCC and in 359 patients with chronic hepatitis B. According to tumour size and serum level of HBV DNA, HBV-related HCC patients were divided into the following categories: Early-stage HCC patients, HCC patients, HBV DNA positive (HBV DNA+) HCC patients, and HBV DNA negative (HBV DNA-) HCC patients. Receiver-operating characteristic (ROC) curves were used to analyse and compare the diagnostic value of the single and combined detection of various biomarkers in different types of HBV-related HCC. RESULTS Tumour size was positively correlated with serum levels of PIVKA-II and AFP in HCC patients (r = 0.529, aP < 0.001 and r = 0.270, bP < 0.001, respectively), but there was no correlation between tumour size and the γ-GT/AST ratio (r = 0.073, P = 0.336). The areas under the receiver-operating characteristic curves (AUROCs) of the γ-GT/AST ratio in early-stage HCC patients, HBV DNA+ HCC patients and HBV DNA- HCC patients were not significantly different from that in the total HCC patients (0.754, 0.802, and 0.705 vs 0.779, respectively;P > 0.05). When PIVKA-II was combined with the γ-GT/AST ratio in the diagnosis of earlystage HCC, HCC, and HBV DNA+ HCC, the AUROCs of PIVKA-II increased, with values of 0.857 vs 0.835, 0.925 vs 0.913, and 0.958 vs 0.954, respectively. When AFP was combined with the γ-GT/AST ratio in the diagnosis of early-stage HCC, HCC, HBV DNA+ HCC, and HBV DNA- HCC, the AUROCs of AFP increased, with values of 0.757 vs 0.621, 0.837 vs 0.744, 0.868 vs 0.757, and 0.840 vs 0.828, respectively. CONCLUSION The γ-GT/AST ratio may be better than PIVKA-II and AFP in the diagnosis of early-stage HBV-related HCC, and its combination with PIVKA-II and AFP can improve the diagnostic value for HBV-related HCC. 展开更多

BACKGROUND: Alpha-fetoprotein (AFP) is the most established tumor marker of hepatocellular carcinoma (HCC), but one of its limitations is non-specificity. Many studies have demonstrated that alpha-fetoprotein-L3 (AFP-L3) is more specific than AFP in the early diagnosis and prognosis of HCC. However, there is a lack of knowledge about the post-hepatectomy profiles of serum AFP and AFP-L3 values in HCC patients. To identify the profiles after surgical resection of HCC, we analyzed the correlation between the profiles and postoperative HCC recurrence or survival, and evaluated their utility in predicting postoperative therapeutic efficacy and prognosis. METHODS: From August 2003 to December 2004, 318 patients with positive serum AFP who had received surgical resections were enrolled in this study. Preoperative and postoperative serum AFP and AFP-L3 levels were measured simultaneously and regularly, and their postoperative profiles during a long term follow-up were recorded and summarized. RESULTS: A high ratio of AFP-L3 to total AFP was shown to correlate with pathologic features of aggressiveness. The overall 1-, 3-, and 5-year recurrence rates of the whole series were 28% 57%, and 84%, and the overall survival rates were 86%, 61% and 33%, respectively. The changes of serum AFP and AFP-L3 after hepatectomy for HCC were classified into 3 groups (group A: AFP-L3 undetectable; group B: AFP-L3 <10%; and group C: AFP-L3 >10%). Patients with positive postoperative AFP-L3had significantly earlier recurrence than those with negative results. The overall survival was significantly shorter in the positive groups than in the groups negative for postoperative AFP-L3.CONCLUSION: Post-hepatectomy changes in serum AFP and AFP-L3 levels occurred in three distinct patterns, which were closely correlated with HCC recurrence and patient survival with different prognostic values. 展开更多

AIM To investigate whether the change in pre-/post-operation serum alpha-fetoprotein(AFP) levels is a predictive factor for hepatocellular carcinoma(HCC) outcomes.METHODS We retrospectively analyzed 334 HCC patients who underwent hepatic resection at our hospital between January 2006 and December 2016. The patients were classified into three groups according to their change in serum AFP levels:(1) the normal group, pre-AFP ≤ 20 ng/m L and post-AFP ≤ 20 ng/m L;(2) the response group, pre-AFP > 20 ng/m L and post-AFP decrease of ≥ 50% of pre-AFP; and(3) the non-response group, pre-AFP level > 20 ng/m L and post-AFP decrease of < 50% or higher than pre-AFP level, or any pre-AFP level < 20 ng/m L but post-AFP >20 ng/m L RESULTS Univariate and multivariate analyses revealed thatmultiple tumors [hazard ratio(HR): 1.646, 95%CI: 1.15-2.35, P < 0.05], microvascular invasion(m VI)(HR: 1.573, 95%CI: 1.05-2.35, P < 0.05), and the nonresponse group(HR: 2.425, 95% CI: 1.42-4.13, P < 0.05) were significant independent risk factors for recurrencefree survival. Similarly, multiple tumors(HR: 1.99, 95%CI: 1.12-3.52, P < 0.05), m VI(HR: 3.24, 95%CI: 1.77-5.90, P < 0.05), and the non-response group(HR: 3.62, 95%CI: 1.59-8.21, P < 0.05) were also significant independent risk factors for overall survival. The nonresponse group had significantly lower overall survival rates and recurrence-free survival rates than both the normal group and the response group(P < 0.05). Thus, patients with no response regarding post-surgery AFP levels were associated with poor outcomes.CONCLUSION Serum AFP responses are significant prognostic factors for the surgical outcomes of HCC patients, suggesting post-resection AFP levels can direct the management of HCC patients. 展开更多

AIM: To determine the predictive value of increased prolidase activity that reflects increased collagen turnover in patients with hepatocellular carcinoma(HCC).METHODS: Sixty-eight patients with HCC(mean age of 69.1 ± 10.1), 31 cirrhosis patients(mean age of59.3 ± 6.3) and 33 healthy volunteers(mean age of51.4 ± 12.6) were enrolled in this study. Univariate and multivariate analysis were used to evaluate the association of serum α-fetoprotein(AFP) values with HCC clinicopathological features, such as tumor size,number and presence of vascular and macrovascular invasion. The patients with HCC were divided into groups according to tumor size, number and presence of vascular invasion(diameters; ≤ 3 cm, 3-5 cmand ≥ 5 cm, number; 1, 2 and ≥ 3, macrovascular invasion; yes/no). Barcelona-clinic liver cancer(BCLC)criteria were used to stage HCC patients. Serum samples for measurement of prolidase and alphafetoprotein levels were kept at-80 ℃ until use.Prolidase levels were measured spectrophotometrically and AFP concentrations were determined by a chemiluminescence immunometric commercial diagnostic assay.RESULTS: In patients with HCC, prolidase and AFP values were evaluated according to tumor size, number,presence of macrovascular invasion and BCLC staging classification. Prolidase values were significantly higher in patients with HCC compared with controls(P <0.001). Prolidase levels were significantly associated with tumor size and number(P < 0.001, P = 0.002,respectively). Prolidase levels also differed in patients in terms of BCLC staging classification(P < 0.001).Furthermore the prolidase levels in HCC patients showed a significant difference compared with patients with cirrhosis(P < 0.001). In HCC patients grouped according to tumor size, number and BCLC staging classification, AFP values differed separately(P = 0.032,P = 0.038, P = 0.015, respectively). In patients with HCC, there was a significant correlation(r = 0.616; P< 0.001) between prolidase and AFP values in terms of tumor size, number and BCLC staging classification,whereas the presence of macrovascular invasion did not show a positive association with serum prolidase and AFP levels.CONCLUSION: Considering the levels of both serum prolidase and AFP could contribute to the early diagnosing of hepatocellular carcinoma. 展开更多

Background: As a promising biomarker of hepatocellular carcinoma(HCC), protein induced by vitamin K absence or antagonist-Ⅱ(PIVKA-Ⅱ) has been studied extensively. However, its diagnostic capability varies across HCC studies. This study aimed to compare the performance of PIVKA-Ⅱ with alpha-fetoprotein(AFP) in the diagnosis of HCC. Data sources: A systematic literature search was conducted to identify the studies from MEDLINE, Embase and Cochrane Library Databases, which were published up to December 20, 2017 to compare the diagnostic capability of PIVKA-Ⅱ and AFP for HCC. The data were pooled using random effects model. Pooled sensitivity and specificity were calculated. Summary receiver operating characteristic curve(ROC) was employed to evaluate the diagnostic accuracy of each marker. Results: Thirty-one studies were included. The pooled sensitivity(95% CI) of PIVKA-Ⅱ and AFP was 0.66(0.65–0.68) and 0.66(0.65–0.67), respectively in diagnosis of HCC; and the corresponding pooled specificity(95% CI) was 0.89(0.88–0.90) and 0.84(0.83–0.85), respectively. The area under the ROC curve(AUC) of PIVKA-Ⅱ and AFP was 0.856(0.817–0.895) and 0.770(0.728–0.811), respectively. Subgroup analysis showed that PIVKA-Ⅱ was superior to AFP in terms of the AUC for both small HCC( < 3 cm) [0.863(0.825–0.901) vs 0.717(0.658–0.776)] and large HCC( ≥ 3 cm) [0.854(0.811–0.897) vs 0.729(0.682–0.776)]; for American [0.926(0.897–0.955) vs 0.698(0.594–0.662)], European [0.772(0.743–0.801) vs 0.628(0.594–0.662)], Asian [0.838(0.812–0.864) vs 0.785(0.764–0.806)] and African [0.812(0.794–0.840) vs 0.721(0.675–0.767)] HCC patients; and for HBV-related [0.909(0.866–0.951) vs 0.714(0.673–0.755)] and mixed-etiology [0.847(0.821–0.873) vs 0.794(0.772–0.816)] HCC. Conclusion: This meta-analysis indicates that PIVKA-Ⅱ is better than AFP in terms of the accuracy for diagnosing HCC, regardless of tumor size, patient ethnic group, or HCC etiology. 展开更多

BACKGROUND: In liver transplantation or resection for hepatocellular carcinoma (HCC), patient selection depends on morphological features. In patients with HCC, we performed a clinicopathological analysis of risk factors that affected survival after liver transplantation. METHODS: In 389 liver transplantations performed from 2004 to 2010, 102 were for HCC patients. Data were collected retrospectively from the Organ Transplantation Center Database. Variables were as follows: age, gender, preoperative alpha-fetoprotein (AFP) levels, Child-Pugh and MELD scores, prognostic staging criteria (Milan and UCSF), etiology, number of tumors, the largest tumor size, total tumor size, multifocality, intrahepatic portal vein tumor thrombosis, bilobarity, and histological differentiation. RESULTS: One hundred and two patients were evaluated. The 5-year overall survival rate was 56.5%. According to the UCSF criteria, 63% of the patients were within and 37% were beyond UCSF (P=0.03). Ten patients were excluded (one with fibrolamellary HCC and 9 because of early postoperative death without HCC recurrence), and 92 patients were assessed. The mean age of the patients was 56.5±6.9 years. Sixty-two patients underwent living donor liver transplantations. The mean follow-up time was 29.4±22.6 months. Fifteen patients (16.3%) died in the follow-up period due to HCC recurrence. Univariate analysis showed that AFP level, intrahepatic portal vein tumor thrombosis, histologic differentiation and UCSF criteria were significant factors related to survival and tumor recurrence. The 5-year estimated overall survival rate was 62.2% in allpatients. According to the UCSF criteria, and the 5-year overall survival rate was 66.7% within and 52.7% beyond the criteria (P=0.04). Multivariate analysis showed that AFP level and poor differentiation were independent factors. CONCLUSIONS: For proper patient selection in liver trans- plantation for HCC, prognostic criteria related to tumor biology (especially AFP level and histological differentiation) should be considered. Poor differentiation and higher AFP levels are indicators of poor prognosis after liver transplantation. 展开更多

The presence of CD8 T cell responses to tumor associated antigens have been reported in patients with different malignancies. However, there is very little inf ormation on a comparable CD8 and CD4 T cell response to a tumor antigen in liver cancer patients. Here, we re-examine the kinetic and the pattern of T helper 1 and cytotoxic T lymphocyte responses to alpha-fetoprotein (AFP),a tumor rejection antigen in hepatocellular carcinoma (HCC). Then, we discuss the possibility of using AFP-based immunotherapy in combination with necrotizing treatments in HCC patients. 展开更多

AIM: To characterize the alpha-fetoprotein (AFP) positive and negative hepatocellular carcinoma (HCC) samples. METHODS: Thirty-seven paraffin-embedded human HCC samples were analyzed by immunohistochemistry for the following antigens: AFP,β-catenin, p53, CD44, MSH-2, MLH-1, and HNF-4. The tumors were divided into two groups based on the AFP expression. The immunophenotypic data and important clinical parameters were studied between the two groups. RESULTS: Twenty-one of the thirty-seven examined HCCs were AFP positive. Seven with nudear p53 staining were AFP positive, while seven tumors with nuclear β-catenin staining were AFP negative. CD44 staining and high histological tumor grade were more frequent among the AFP-positive HCCs. The other immunophenotypical and dinical parameters did not show statistically significant difference in their distribution between the AFP positive and negative samples. CONCLUSION: AFP expression in HCC correlates with unfavorable prognostic factors, while nuclear β-catenin positivity is more common among the AFP-negative liver tumors. This observation supports the microarray data on in vivo human tumors. 展开更多

Hepatocellular carcinoma (HCC) is one of the most common cancers in Eastern Asia, and its incidence is increasing globally. Numerous experimental models have been developed to better our understanding of the pathogenic mechanism of HCC and to evaluate novel therapeutic approaches. Molecular imaging is a convenient and up-to-date biomedical tool that enables the visualization, characterization and quantification of biologic processes in a living subject. Molecular imaging based on reporter gene expression, in particular, can elucidate tumor-specific events or processes by acquiring images of a reporter gene&#x02019;s expression driven by tumor-specific enhancers/promoters. In this review, we discuss the advantages and disadvantages of various experimental HCC mouse models and we present in vivo images of tumor-specific reporter gene expression driven by an alpha-fetoprotein (AFP) enhancer/promoter system in a mouse model of HCC. The current mouse models of HCC development are established by xenograft, carcinogen induction and genetic engineering, representing the spectrum of tumor-inducing factors and tumor locations. The imaging analysis approach of reporter genes driven by AFP enhancer/promoter is presented for these different HCC mouse models. Such molecular imaging can provide longitudinal information about carcinogenesis and tumor progression. We expect that clinical application of AFP-targeted reporter gene expression imaging systems will be useful for the detection of AFP-expressing HCC tumors and screening of increased/decreased AFP levels due to disease or drug treatment. 展开更多

Alpha-fetoprotein(AFP) is the main tumor biomarker available for the management of hepatocellular carcinoma(HCC). Although it is neither a good screening test nor an accurate diagnostic tool for HCC, it seems to be a possible prognostic marker. However, its contribution in liver transplantation for HCC has not been fully determined, although its use to predict recurrence after liver transplantation has been underlined by international societies. In an era of organ shortages, it could also have a key role in the selection of patients eligible for liver transplantation. Yet unanswered questions remain. First, the cut-off value of serum AFP above which liver transplantation should not be performed is still a subject of debate. We show that a concentration of 1000 ng/m L could be an exclusion criterion, whereas values of < 15 ng/m L indicate patients with an excellent prognosis whatever the size and number of tumors. Monitoring the dynamics of AFP could also prove useful. However, evidence is lacking regarding the values that should be used. Today, the real input of AFP seems to be its integration into new criteria to select patients eligible for a liver transplantation. These recent tools have associated AFP values with morphological criteria, thus refining pre-existing criteria, such as Milan, University of California, San Francisco, or "up-to-seven". We provide a review of the different criteria submitted within the past years. Finally, AFP can be used to monitor recurrence after transplantation, although there is little evidence to support this claim. Future challenges will be to draft new international guidelines to implement the use of AFP as a selection tool, and to determine a clear cut-off value above which liver transplantation should not be performed. 展开更多
