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: The existence and properties of alpha-fetoprotein (AFP) receptor on the surface of NIH 3T3 cells and the effects of AFP on cellular signal transduction pathway were investigated. METHODS: The effect of AFP on the proliferation of NIH 3T3 cells was measured by incorporation of 3H-TdR. Receptor-binding assay of 125I-AFP was performed to detect the properties of AFP receptor in NIH 3T3 cells. The influences of AFP on the [cAMP]i and the activities of protein kinase A (PKA) were determined. Western blot was used to detect the change of K-ras P21 protein expression. RESULTS: The proliferation of NIH 3T3 cells treated with 0-80 mg/L of AFP was significantly enhanced. The Scatchard analysis indicated that there were two classes of binding sites with KD of 2.722 x 10(-9)M (Bmax=12810 sites per cell) and 8.931 x 10(-8)M (Bmax=119700 sites per cell) respectively. In the presence of AFP (20 mg/L), the content of cAMP and activities of PKA were significantly elevated . The level of K-ras P21 protein was upregulated by AFP at the concentration of 20 mg/L. The monoclonal antibody against AFP could reverse the effects of AFP on the cAMP content, PKA activity and the expression of K-ras p21 gene. CONCLUSION: The effect of AFP on the cell proliferation was achieved by binding its receptor to trigger the signal transduction pathway of cAMP-PKA and alter the expression of K- ras p21 gene. 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

BACKGROUND Hepatocellular carcinoma(HCC)ranks second in terms of cancer mortality worldwide.Molecular magnetic resonance imaging(MRI)targeting HCC biomarkers such as alpha-fetoprotein(AFP)or glypican-3(GPC3)offers new strategies to enhance specificity and help early diagnosis of HCC.However,the existing iron oxide nanoparticle-based MR molecular probes singly target AFP or GPC3,which may hinder their efficiency to detect heterogeneous micro malignant HCC tumors<1 cm(MHCC).We hypothesized that the strategy of double antibody-conjugated iron oxide nanoparticles which simultaneously target AFP and GPC3 antigens may potentially be used to overcome the tumor heterogeneity and enhance the detection rate for MRI-based MHCC diagnosis.AIM To synthesize an AFP/GPC3 double antibody-labeled iron oxide MRI molecular probe and to assess its impact on MRI specificity and sensitivity at the cellular level.METHODS A double antigen-targeted MRI probe for MHCC anti-AFP-USPIO-anti-GPC3(UAG)was developed by simultaneously conjugating AFP andGPC3 antibodies to a 5 nm ultra-small superparamagnetic iron oxide nanoparticle(USPIO).At the same time,the singly labeled probes of anti-AFP-USPIO(UA)and anti-GPC3-USPIO(UG)and non-targeted USPIO(U)were also prepared for comparison.The physical characterization including morphology(transmission electron microscopy),hydrodynamic size,and zeta potential(dynamic light scattering)was conducted for each of the probes.The antigen targeting and MRI ability for these four kinds of USPIO probes were studied in the GPC3-expressing murine hepatoma cell line Hepa1-6/GPC3.First,AFP and GPC3 antigen expression in Hepa1-6/GPC3 cells was confirmed by flow cytometry and immunocytochemistry.Then,the cellular uptake of USPIO probes was investigated by Prussian blue staining assay and in vitro MRI(T2-weighted and T2-map)with a 3.0 Tesla clinical MR scanner.RESULTS Our data showed that the double antibody-conjugated probe UAG had the best specificity in targeting Hepa1-6/GPC3 cells expressing AFP and GPC3 antigens compared with single antibody-conjugated and unconjugated USPIO probes.The iron Prussian blue staining and quantitative T2-map MRI analysis showed that,compared with UA,UG,and U,the uptake of double antigen-targeted UAG probe demonstrated a 23.3%(vs UA),15.4%(vs UG),and 57.3%(vs U)increased Prussian stained cell percentage and a 14.93%(vs UA),9.38%(vs UG),and 15.3%(vs U)reduction of T2 relaxation time,respectively.Such bi-specific probe might have the potential to overcome tumor heterogeneity.Meanwhile,the coupling of two antibodies did not influence the magnetic performance of USPIO,and the relatively small hydrodynamic size(59.60±1.87 nm)of double antibodyconjugated USPIO probe makes it a viable candidate for use in MHCC MRI in vivo,as they are slowly phagocytosed by macrophages.CONCLUSION The bi-specific probe presents enhanced targeting efficiency and MRI sensitivity to HCC cells than singly-or non-targeted USPIO,paving the way for in vivo translation to further evaluate its clinical potential. 展开更多

AIM To assess the performance of BALAD, BALAD-2 and their component biomarkers in predicting outcome of hepatocellular carcinoma(HCC) patients after liver transplant.METHODS BALAD score and BALAD-2 class are derived from bilirubin, albumin, alpha-fetoprotein(AFP), Lens culinaris agglutinin-reactive AFP(AFP-L3), and des-gammacarboxyprothrombin(DCP). Pre-transplant AFP, AFP-L3 and DCP were measured in 113 patients transplanted for HCC from 2000 to 2008. Hazard ratios(HR) for recurrence and death were calculated. Univariate and multivariate regression analyses were conducted. C-statistics were used to compare biomarker-based to predictive models. RESULTS During a median follow-up of 12.2 years, 38 patients recurred and 87 died. The HRs for recurrence in patients with elevated AFP, AFP-L3, and DCP defined by BALAD cut-off values were 2.42(1.18-5.00), 1.86(0.98-3.52), and 2.83(1.42-5.61), respectively. For BALAD, the HRs for recurrence and death per unit increased score were 1.48(1.15-1.91) and 1.59(1.28-1.97). For BALAD-2, the HRs for recurrence and death per unit increased class were 1.45(1.06-1.98) and 1.38(1.09-1.76). For recurrence prediction, the combination of three biomarkers had the highest c-statistic of 0.66 vs. 0.64, 0.61, 0.53, and 0.53 for BALAD, BALAD-2, Milan, and UCSF, respectively. Similarly, for death prediction, the combination of three biomarkers had the highest c-statistic of 0.66 vs 0.65,0.61, 0.52, and 0.50 for BALAD, BALAD-2, Milan, and UCSF. A new model combining biomarkers with tumor size at the time of transplant(S-LAD) demonstrated the highest predictive capability with c-statistics of 0.71 and 0.69 for recurrence and death. CONCLUSION BALAD and BALAD-2 are valid in transplant HCC patients, but less predictive than the three biomarkers in combination or the three biomarkers in combination with maximal tumor diameter(S-LAD). 展开更多

BACKGROUND Hepatocellular carcinoma(HCC)is the second leading cause of cancer-related mortality.HCC-targeted magnetic resonance imaging(MRI)is an effective noninvasive diagnostic method that involves targeting clinically-related HCC biomarkers,such as alpha-fetoprotein(AFP)or glypican-3(GPC3),with iron oxide nanoparticles.However,in vivo studies of HCC-targeted MRI utilize single-target iron oxide nanoprobes as negative(T2)contrast agents,which might weaken their future clinical applications due to tumor heterogeneity and negative MRI contrast.Ultra-small superparamagnetic iron oxide(USPIO)nanoparticles(approximately 5 nm)are potential optimal positive(T1)contrast agents.We previously verified the efficiency of AFP/GPC3-double-antibody-labeled iron oxide MR molecular probe in vitro.AIM To validate the effectiveness of a bi-specific probe in vivo for enhancing T1-weighted positive contrast to diagnose the early-stage HCC.METHODS The single-and double-antibody-conjugated 5-nm USPIO probes,including antiAFP-USPIO(UA),anti-GPC3-USPIO(UG),and anti-AFP-USPIO-anti-GPC3(UAG),were synthesized.T1-and T2-weighted MRI were performed on day 10 after establishment of the orthotopic HCC mouse model.Following intravenous injection of U,UA,UG,and UAG probes,T1-and T2-weighted images were obtained at 12,12,and 32 h post-injection.At the end of scanning,mice were euthanized,and a histologic analysis was performed on tumor samples.RESULTS T1-and T2-weighted MRI showed that absolute tumor-to-background ratios in UAG-treated HCC mice peaked at 24 h post-injection,with the T1-and T2-weighted signals increasing by 46.7%and decreasing by 11.1%,respectively,relative to pre-injection levels.Additionally,T1-weighted contrast in the UAG-treated group at 24 h post-injection was enhanced 1.52-,2.64-,and 4.38-fold compared to those observed for single-targeted anti-GPC3-USPIO,anti-AFP-USPIO,and nontargeted USPIO probes,respectively.Comparison of U-,UA-,UG-,and UAG-treated tumor sections revealed that UAG-treated mice exhibited increased stained regions compared to those observed in UG-or UA-treated mice.CONCLUSION The bi-specific T1-positive contrast-enhanced MRI probe(UAG)for HCC demonstrated increased specificity and sensitivity to diagnose early-stage HCC irrespective of tumor size and/or heterogeneity. 展开更多

The disease burden of hepatocellular carcinoma (HCC) in China is heavy, and the prognosis is stillunfavourable. Therefore, early screening of high-risk groups of HCC through simple methods is the key toachieving early diagnosis and treatment and improving survival. At present, alpha-fetoprotein and otherhematological tests are still the main methods in the early screening of HCC, but the sensitivity andspecificity are limited, and the risk of missed diagnosis is high. In recent years, with the continuousdevelopment of science and technology, the improvement of traditional detection methods and theemergence of novel markers such as methylated deoxyribonucleic acid and microRNA have brought hopefor further improving the sensitivity and specificity of early HCC screening. This consensus summarizesthe research progress of traditional and new hematological test methods and puts forward expertguidance on the role of hematological markers in the early screening of HCC to provide a basis forimproving the prevention and control level in China. 展开更多
