Abstract
PURPOSE Treatment of hypovascular tumors, such as pancreatic adenocarcinoma, is challenging owing to inefficient drug delivery. This report examines the potential mechanism of localized drug delivery via transarterial microperfusion (TAMP) using a proprietary adjustable double-balloon occlusion catheter in a porcine model. MATERIALS AND METHODS Adult Yorkshire swine (N = 21) were used in the Institutional Animal Care & Use Committee-approved protocols. The RC-120 catheter (RenovoRx, Los Altos, California) was positioned into visceral, femoral, and pulmonary arteries with infusion of methylene blue dye, gemcitabine, or gold nanoparticles. Transmural delivery was compared under double-balloon occlusion with and without side-branch exclusion, single-balloon occlusion, and intravenous delivery. Intra-arterial pressure and vascular histologic changes were assessed. RESULTS Infusion with double-balloon occlusion and side-branch exclusion provided increased intra-arterial pressure in the isolated segment and enhanced perivascular infusate penetration with minimal vascular injury. Infusates were predominantly found in the vasa vasorum by electron microscopy. CONCLUSIONS TAMP enhanced transmural passage mediated by localized increase in arterial pressure via vasa vasorum.

Cost-effectiveness and prognostic model of hepatic arterial infusion chemotherapy for hepatocellular carcinoma with high tumor burden and/or Vp4 tumor thrombus compared with sorafenib: a post-hoc analysis of the FOHAIC-1 trial. Int J Surg 2023; 109:3929-3939. [PMID: 37678272 PMCID: PMC10720800 DOI: 10.1097/js9.0000000000000683] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/25/2023] [Accepted: 08/06/2023] [Indexed: 09/09/2023]
Abstract
OBJECTIVES The phase III FOHAIC-1 trial revealed that hepatic arterial infusion of chemotherapy (HAIC) improved overall survival compared to sorafenib in the high-risk hepatocellular carcinoma (HCC). This study therefore set out to evaluate the cost-effectiveness and establish a prognostic clinico-radiological score of HAIC. MATERIALS AND METHODS A total of 409 patients with high-risk HCC who received HAIC between 2014 and 2020 were included. A Markov model was applied in the cost-effectiveness analysis using data from the FOHAIC-1 trial. In prognosis analysis, a clinico-radiological score was developed using a Cox-regression model and subsequently confirmed in the internal validation and test cohorts. The area under the curve from receiver operator characteristic analysis was used to assess the performance of the clinico-radiological score. RESULTS HAIC resulted in an incremental cost-effectiveness ratio of $10190.41/quality-adjusted life years compared to sorafenib, which was lower than the willingness-to-pay threshold. Probabilistic sensitivity analysis predicted a ≥99.9% probability that the incremental cost-effectiveness ratio was below the willingness-to-pay. The Cox analysis identified five factors, namely extrahepatic metastasis (m), arterial enhancing type (a), tumor number (nu), albumin-bilirubin index (a), and involved lobe (l), which together comprise the clinico-radiological score (HAIC-manual). Patients were classified into three groups based on the number of factors present, with cutoffs at 2 and 4 factors. The stratified median overall survival for these groups were 21.6, 10.0, and 5.9 months, respectively ( P <0.001). These findings were verified through internal validation and test cohorts with a significance level of P ≤0.01. The time-dependent area under the curve from receiver operator characteristic for the ability of the HAIC-manual to predict survival in 1, 2, and 3 years were 0.71, 0.76, and 0.78, which significantly outperformed existing staging systems. CONCLUSION HAIC is a promising and cost-effective strategy for patients with high-risk HCC. The clinico-radiological score may be a simple prognostic tool for predicting HAIC treatment.

Abstract
BACKGROUND Information regarding the therapeutic effect and outcome of transcatheter arterial embolization (TAE) for hepatic masses is limited in veterinary medicine. HYPOTHESIS/OBJECTIVES To analyze the therapeutic response, outcome (overall survival), and their predictors in dogs that underwent TAE for primary hepatocellular masses. We hypothesized that larger pre-TAE tumors would be associated with worse outcomes. ANIMALS Fourteen client-owned dogs. METHODS Retrospective study. Medical records between 1 September 2016 and 30 April 2022 were reviewed to identify dogs treated with TAE for hepatic masses diagnosed as hepatocellular origin by cytological or histopathological examination. Computed tomography images were compared before and after TAE. The univariate Cox proportional hazards test was performed to assess the associations between variables and survival. Univariate linear regression analysis was performed to assess the associations between variables and the tumor reduction percentage: ([post-TAE volume - pre-TAE volume]/pre-TAE volume) × 100. RESULTS The median survival time was 419 days (95% confidence interval, 82-474). History of intra-abdominal hemorrhage (P = .03) and pre-TAE tumor volume/body weight (P = .009) were significantly associated with overall survival. The mean reduction percentage was -51% ± 40%. Pre-TAE tumor volume/body weight ratio (cm3 /kg; P = .02, correlation coefficient = 0.704) was significantly correlated with the volume reduction percentage. CONCLUSIONS History of intra-abdominal hemorrhage and large pre-TAE tumor volume/body weight ratio could be predictive factors for adverse outcomes after TAE. Pre-TAE tumor volume/body weight ratio could be a predictive factor for therapeutic effect.

Abstract
Gastric cancer is the second most prevalent cancer and the second leading cause of cancer-related death in China. The prognosis of metastatic gastric cancer is poor with a median overall survival of 8–10 months. Apatinib, an oral small-molecule, selective vascular endothelial growth factor receptor-2 tyrosine kinase inhibitor, is approved as third-line or subsequent therapy for gastric cancer in China. Several recent small-scale studies and case reports showed that it may be great help in improvement of prognosis as second-line treatment in patients with advanced or metastatic gastric cancer. Here, we present a case of advanced gastric adenocarcinoma with multiple hepatic metastases who was treated with apatinib plus paclitaxel as second-line therapy, realized a long progression-free survival of 37 months. Until 29 January 2022, the disease remains an efficacy of partial response. We believe that the good outcome of this case is not an accident, because of the typically hyper-vascular of his liver metastases, the treatment toxicities of hypertension and proteinuria, all may be potential predictive biomarkers for anti-angiogenic treatments.

Abstract
Objective To validate the robust predictive values of tumor vascularity and reactive cutaneous capillary endothelial proliferation (RCCEP) in combination treatment of transarterial chemoembolization (TACE) and camrelizumab for patients with advanced hepatocellular carcinoma (HCC) and then select the potential candidates who would survive best from such treatment. Methods The clinical data of 113 patients with advanced HCC treated with TACE and camrelizumab from January 2019 to December 2021 were analyzed retrospectively. Mann Whitney U-test was used to evaluate the correlation between vascular distribution and RCCEP and tumor response; Kaplan Meier technique was used to evaluate time to progress (TTP) and overall survival (OS), and log rank test was used for comparison; multivariate Cox regression analysis was used to evaluate the related influencing factors. Results The TTP and OS of TACE combined with carrelizumab in patients with advanced HCC were 7.1 and 14.3 months. Hypervascularity and development of RCCEP were good predictors of TTP (HR 2.561, P < 0.001; HR 1.486, P = 0.032) and OS (HR 2.854, P < 0.001; HR 1.634, P = 0.011). The median TTP and OS of patients with hypervascularity and RCCEP were 10.6 and 19.3 months, which were better than those with only hypervascularity (6.8 months, P = 0.016; 11.6 months, P = 0.003) and only RCCEP (6.2 months, P = 0.039; 13.5 months, P = 0.042), as well as those with neither (3.8 months, P < 0.001; 7.4 months, P < 0.001). Conclusion Tumor hypervascularity and development of RCCEP were favorable predictive factors for the combination treatment of TACE and carrelizumab, with both of which the patients survived longest and might be the potential candidates.

Abstract
OBJECTIVE. The goal of this study was to evaluate radiologic and clinical factors associated with overall survival of advanced hepatocellular carcinoma treated with hepatic arterial infusion chemotherapy (HAIC). MATERIALS AND METHODS. This single-center retrospective study included 180 patients with advanced hepatocellular carcinoma who underwent HAIC with a 5-fluorouracil (250-500 mg/m2 for 5 hours) plus cisplatin (10-20 mg/m2 for 1-2 hours) regimen via an implantable port system. Survival curves were generated by the Kaplan-Meier method and compared by log-rank tests. Factors associated with overall survival were evaluated with Cox proportional hazard models. RESULTS. The median overall survival time was 7.6 months (95% CI, 6.1-9.1), and the objective response rate was 15%. In multivariate analysis, infiltrative tumor growth (hazard ratio [HR], 1.002; p = .03) and rimlike arterial enhancement (HR, 3.040; p < .001) were pretreatment radiologic factors associated with reduced overall survival. No early response to treatment (HR, 2.064-6.491) and higher Child-Pugh class (HR, 2.010-2.815) were strong prognostic factors of poor outcome. Treatment with three or more HAIC cycles (HR, 0.371; p = .001) and high-dose HAIC (HR, 0.447; p < .001) were favorable for increased overall survival. CONCLUSION. Infiltrative tumor growth and rimlike arterial enhancement in pre-treatment imaging studies were associated with poor prognosis, and better early radiologic response and preserved liver function reserve were strong indicators of prolonged survival. Recognizing these radiologic and clinical predictors may help optimize care of patients with hepatocellular carcinoma.

Abstract
Despite the application of antiviral drugs and improved surveillance tools, the number of patients diagnosed with hepatocellular carcinoma (HCC) at an advanced stage and with a dismal prognosis is still on the rise. Systemic treatment with multiple multitargeted tyrosine kinase inhibitors (TKIs), such as sorafenib, has been a widely utilized approach for a decade. In addition, the use of a combination of TKIs with other types of compounds, including immune checkpoint inhibitors (ICIs) and antiangiogenic inhibitors, has shown efficacy in treating advanced HCC. However, the presence of intolerable adverse events, low disease response and control rates, and relative short overall survival of such combinatory therapies makes novel or optimized therapies for advance HCC urgently needed. Locoregional therapy (transarterial chemoembolization, and thermal ablation) can destroy primary tumors and decrease tumor burden and is widely used for HCC management. This type of treatment modality can result in local hypoxia and increased vascular permeability, inducing immunogenic effects by releasing tumor antigens from dying cancer cells and producing damage-associated molecular patterns that facilitate antiangiogenic therapy and antitumor immunity. The combination of systemic and locoregional therapies may further produce synergistic effects without overlapping toxicity that can improve prognoses for advanced HCC. In preliminary studies, several combinations of therapeutic modes exhibited promising levels of safety, feasibility, and antitumor effects in a clinical setting and have, thus, garnered much attention. This review aims to provide a comprehensive, up-to-date overview of the underlying mechanisms of combined systemic and locoregional therapies in the treatment of advanced HCC, commenting on both their current status and future direction.

Abstract
Objective: To confirm the feasibility and accuracy of the method for evaluating blood supply and embolization rate of liver cancer based on I-flow software through animal experiments and clinical study. Methods: Rabbits underwent selective angiography under different perfusion conditions in the same kidney. The blood supply level was evaluated by I-flow software method. The results were analyzed for coefficient of variation. Thirty patients with liver cancer who underwent selective hepatic artery embolization were enrolled. The mathematical methods and 3 diagnostic specialists were used to evaluate the preoperative blood supply level and embolization rate. The results were recorded and the results were tested for consistency. Results: Animal experiments confirmed that the blood supply level analysis method designed by the research team was consistent under different contrast conditions (including total contrast agent, contrast medium perfusion rate, and limiting pressure) (coefficient of variation: 8.55%). The mathematical calculation results of preoperative blood supply level and embolization ratio of liver cancer are consistent with the average value of visual judgment results of diagnostic experts. (Preoperative blood supply level: concordance coefficient = 0.284, P = 0.003; embolization ratio: concordance coefficient = 0.218, P = 0.011). Conclusion: Based on I-flow software, the mathematical calculation method designed by this research group can effectively estimate the preoperative blood supply level of liver cancer and the embolization rate of single vascular embolization treatment, which can provide reliable data support for embolization treatment of liver cancer.

Abstract
BACKGROUND To validate the robust predictive values of tumor vascularity and hand-foot-skin reaction (HFSR) in combination treatment of transarterial chemoembolization (TACE) and sorafenib for patients with intermediate hepatocellular carcinoma (HCC), and then select the potential candidates who would survive best from such treatment. METHODS A total of 132 treatment-naive patients with intermediate HCC undergoing combination therapy of TACE and sorafenib were recruited between January 2010 and December 2014. The tumor vascularity was defined according to digital subtraction angiography (DSA) and HFSR was assessed by the national cancer institute common terminology criteria for adverse events (NCI-CTCAE). The Mann-Whitney U test was used to assess the correlation between vascularity and radiologic response; time to radiologic progression (TTP) and overall survival (OS) were evaluated using Kaplan-Meier techniques and compared by log-rank test; factors associated with them were evaluated using multivariate Cox regression analysis. RESULTS During a median follow up of 17.3 months, it was revealed that hypervascularity and development of ≥2 grade of HFSR within 60 days after sorafenib initiation were favorable predictors for TTP (HR 0.378, p < 0.001; HR 0.627, p = 0.018) and OS (HR 0.499, p = 0.002; HR 0.555, p = 0.004). The median TTP and OS for patients with both were 12.2 and 29.1 months, which were better than patients with either of them (6.0 months, HR 1.74, p = 0.012; 16.5 months, HR 1.73, p = 0.021), as well as those with neither (2.9 months, HR 3.74, p < 0.001; 11.9 months, HR 3.17, p < 0.001). CONCLUSIONS Tumor hypervascularity and development of ≥2 grade of HFSR within 60 days were favorable predictive factors for the combination treatment of TACE and sorafenib, with both of which the patients survived longest and might be the potential candidates.

Does Enhancement or Perfusion on Preprocedure CT Predict Outcomes After Embolization of Hepatocellular Carcinoma? Acad Radiol 2018; 25:1588-1594. [PMID: 29602726 DOI: 10.1016/j.acra.2018.02.027] [Citation(s) in RCA: 18] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/19/2017] [Revised: 02/26/2018] [Accepted: 02/28/2018] [Indexed: 12/17/2022]
Abstract
RATIONALE AND OBJECTIVE The objective of this study was to evaluate whether quantitative enhancement or perfusion measurements on preprocedure triphasic computed tomography (CT) can be used to predict response or overall survival after embolization of hepatocellular carcinoma. MATERIALS AND METHODS The institutional review board approved this retrospective review of 63 patients with hepatocellular carcinoma treated with particle embolization between March 2009 and December 2014. Quantitative enhancement and perfusion measurements were performed on the target tumor and the background liver on the triphasic CT performed before treatment. Microvascular invasion (MVI) and degree of differentiation were determined from a core biopsy specimen. Quantitative enhancement and perfusion values were then correlated with pathology (two-tailed t test), response to embolization on modified Response Evaluation Criteria In Solid Tumors (two-tailed t test), and overall survival after embolization (Cox proportional hazards model). RESULTS Arterial enhancement did not predict immediate response or overall survival after embolization. The degree of differentiation or presence of MVI also did not predict immediate response or overall survival after embolization. However, high hepatic artery coefficient or low portal vein coefficient, both in the tumor (P = .011 and P = .004) and in the background liver (P = .015 and P = .009), were associated with worse survival. Hepatic artery coefficient, both in the tumor (P = .025) and in the background liver (P = .013), were independent predictors of survival in a multivariate model including the Child-Pugh score and the BCLC stage. CONCLUSIONS Tumor and liver perfusion parameters estimated from preprocedure triphasic CT were predictive of survival after embolization. Arterial-phase enhancement and histology (degree of differentiation or MVI) did not predict immediate response or overall survival after particle embolization.

Abstract
This study evaluated the factors impacting overall survival (OS) and time to progression (TTP) in patients with unresectable hepatocellular carcinoma (HCC) who received transarterial chemoembolization (TACE). HCC patients were grouped based on tumor vascularity and lipidiol deposition after TACE. Tumor vascularity was classified based on contrast enhancement on arterial phase baseline CT scans. Lipiodol deposition was evaluated using CT scans. The progression-free rate was significantly higher in patients with good blood supply + good lipiodol deposition compared to those with good blood supply + poor lipiodol deposition. In patients with poor lipidiol deposition, risk of death was significantly positively correlated with stage, and negatively correlated with number of TACE procedures and degree of lipidiol deposition after the first TACE. Risk of disease progression in these patients was positively correlated with tumor size, and negatively correlated with number of TACE procedures and degree of lipidiol deposition after the first TACE. Our data showed that tumor vascularity and lipiodol deposition can be used as early radiological markers to identify patients who do not respond to TACE, and who can be considered earlier for alternative combination treatment strategies. Our data also indicated that poor lipiodol retention may predict a poor TTP and OS despite the blood supply status.

Abstract
PURPOSE To evaluate in patients with hepatocellular carcinoma (HCC), whether assessment of tumor heterogeneity by histogram analysis of computed tomography (CT) perfusion helps predicting response to transarterial radioembolization (TARE). MATERIALS AND METHODS Sixteen patients (15 male; mean age 65 years; age range 47-80 years) with HCC underwent CT liver perfusion for treatment planning prior to TARE with Yttrium-90 microspheres. Arterial perfusion (AP) derived from CT perfusion was measured in the entire tumor volume, and heterogeneity was analyzed voxel-wise by histogram analysis. Response to TARE was evaluated on follow-up imaging (median follow-up, 129 days) based on modified Response Evaluation Criteria in Solid Tumors (mRECIST). Results of histogram analysis and mean AP values of the tumor were compared between responders and non-responders. Receiver operating characteristics were calculated to determine the parameters' ability to discriminate responders from non-responders. RESULTS According to mRECIST, 8 patients (50%) were responders and 8 (50%) non-responders. Comparing responders and non-responders, the 50th and 75th percentile of AP derived from histogram analysis was significantly different [AP 43.8/54.3 vs. 27.6/34.3 mL min(-1) 100 mL(-1)); p < 0.05], while the mean AP of HCCs (43.5 vs. 27.9 mL min(-1) 100 mL(-1); p > 0.05) was not. Further heterogeneity parameters from histogram analysis (skewness, coefficient of variation, and 25th percentile) did not differ between responders and non-responders (p > 0.05). If the cut-off for the 75th percentile was set to an AP of 37.5 mL min(-1) 100 mL(-1), therapy response could be predicted with a sensitivity of 88% (7/8) and specificity of 75% (6/8). CONCLUSION Voxel-wise histogram analysis of pretreatment CT perfusion indicating tumor heterogeneity of HCC improves the pretreatment prediction of response to TARE.

Abstract
The purpose of this study was to investigate the utility of MRI findings after drug-eluting beads (DEB) - transcatheter arterial chemoembolization (TACE) for hepatocellular carcinoma in predicting time to progression (TTP). This study included 48 patients with 60 lesions who underwent liver MRI within 3 months after DEB-TACE. MRI was assessed for arterial enhancement pattern, late washout, arterioportal shunt, signal intensity on T2-weighted image, intratumoral septa, enhancing tissue on subtraction images, and treatment response. Cox-regression analysis was performed to identify independent factors to predict TTP. TTP was calculated using the Kaplan-Meier method with the log-rank test. Per lesion, 30 achieved complete remission, 22 had a partial response, and the remaining 8 lesions displayed stable disease on MRI. Arterial enhancement pattern, washout and enhancing tissue on subtraction images from MRI were associated with viable tumor on the last follow-up computerized tomography. Arterial enhancement, washout and enhancing tissue on subtraction images were significant predictors of TTP, but only enhancing tissue on subtraction images remained a significant predictor of TTP (P=0.018) in the multivariate analysis. TTP was longer in the group without enhancing tissue on subtraction images compared to the group with enhancing tissue (601 days vs. 287 days, P<0.001). Enhancing tissue on subtraction images from MRI after DEB-TACE is predictive for longer TTP.

Abstract
OBJECTIVE To determine the degree of tumor necrosis in surgical specimens of hepatocellular carcinomas treated with microspheres preloaded with doxorubicin and to analyze the relationship between the degree of necrosis and a) morphologic factors and b) imaging biomarkers. MATERIAL AND METHODS We studied the livers of 21 patients who had undergone selective arterial chemoembolization with DC beads (Biocompatibles, UK) before receiving liver transplants. RESULTS Imaging techniques detected 43 nodules (mean size, 25 mm). Angiography showed 25 hypervascularized nodules, 12 slightly vascularized nodules, and 6 avascular nodules. A total of 81 hepatocellular carcinomas (mean size, 15 mm) were detected in the specimens: two were capsular and two had vascular infiltration. The mean degree of necrosis after chemoembolization was 39%; necrosis was greater than 60% in 28 hepatocellular carcinomas and less than 60% in 52. The degree of necrosis correlated significantly with the time elapsed between the last chemoembolization treatment and liver transplantation (the degree of necrosis decreased as time increased), with the number of nodules in the specimen, and with capsular infiltration. When imaging techniques detected 1 or 2 nodules, there was a greater probability of achieving greater than 90% necrosis. No relation with the degree of necrosis achieved was found for the size of the nodules detected at imaging, the enhancement pattern, or the number of chemoembolization treatments. CONCLUSION The degree of necrosis achieved depends on the time spent on the waiting list, on the number of nodules in the specimen, and on whether capsular infiltration is present.

Abstract
Chemoembolization and radioembolization are at the core of the treatment of patients with hepatocellular carcinoma who cannot receive potentially curative therapies such as transplantation, resection or percutaneous ablation. They differ in the mechanism of action (ischaemia and increase cytotoxic drug exposure for chemoembolization, internal irradiation for radioembolization) and may target different patient populations. Chemoembolization with cytotoxic drug-eluting beads is a more standardized although not necessarily more effective way of performing chemoembolization. Cytoreduction is achieved in most patients but complete tumor ablation may be achieved and lead to extended survival. Grade 1 level of evidence support the use of chemoembolization for the treatment of patients in the early and intermediate stages while grade 2 evidence supports the use of radioembolization for the treatment of patients in intermediate to advanced stages. Selecting the best candidates for both techniques is still a work in progress that ongoing clinical trials are trying to address.

Abstract
The most common non-surgical approaches for the treatment of localized hepatocellular carcinoma remain hepatic artery-delivered particles laden with chemotherapy (TACE), or radioactive microparticles (TARE). External beam radiotherapy has been an effective option in many parts of the world for selected HCC patients, but now has an expanded role with stereotactic and proton beam technologies. This review focuses on existing evidence and current guidance for utilizing these modalities for localized, but unresectable, non-transplantable HCC patients.x.

Abstract
PURPOSE To determine any differences in patient characteristics and outcomes after transarterial chemoembolization between different viral etiologies of hepatocellular carcinoma (HCC). METHODS This retrospective study consisted of 201 patients undergoing first-time transarterial chemoembolization for unresectable HCC from January to December 2009. The patients were divided into four groups: hepatitis B virus (HBV) only (n = 104), hepatitis C virus (HCV) only (n = 63), HBV and HCV (n = 10), and no viral hepatitis (n = 24). The clinical and laboratory data were obtained from electronic medical records, and imaging findings obtained before transarterial chemoembolization were analyzed. Kaplan-Meier analyses were used to assess the impact of HBV or HCV status, clinical characteristics, and imaging results on overall survival. RESULTS After a median follow-up of 28.3 months ± 16.2, the 1-, 2-, and 3-year overall survival rates were 74.1%, 59.7%, and 53.2%. Patients with HBV had a significant association with younger age (P = .001), higher male-to-female ratio (P = .003), lower alanine aminotransferase levels (P = .018), higher albumin levels (P = .009), and multifocal tumors at diagnosis (P = .04) compared with patients with HCV. Patients with both HBV and HCV had significantly higher serum bilirubin levels compared with the other groups (P = .002). No significant difference was found in overall survival among the different hepatitis groups (P = .943). Multivariate analysis showed that statistically significant determinants for overall survival were Child-Pugh class (P = .002), Barcelona Clinic Liver Cancer stage (P < .001), tumor size (P < .001), and distribution (P < .001). CONCLUSIONS Viral etiology has no correlation with the outcome of patients with HCC undergoing transarterial chemoembolization.

Abstract
AIM: To evaluate the clinical effectiveness of transcatheter arterial chemoembolization (TACE) in patients with nonresectable combined hepatocellular carcinoma (HCC) and cholangiocarcinoma and to analyze the prognostic factors affecting survival of patients after TACE.
METHODS: Clinical data for 50 patients who underwent TACE for nonresectable combined HCC-cholangiocarcinoma were retrospectively analyzed. The survival rate and the prognostic factors affecting patient survival were evaluated.
RESULTS: After TACE, 35 (70%) of the 50 patients were classified as responders having either a partial response or stable disease and 15 (30%) were classified as non-responders. Tumor response was significantly related to tumor vascularity. One (10%) of the 10 patients with hypovascular tumors and 34 (85%) of the 40 patients with hypervascular tumors were responders (P < 0.001). The median survival period was 12.3 months. Multivariable Cox regression analysis proved that tumor size (HR = 2.49, P = 0.028), tumor vascularity (HR = 4.19, P = 0.001), Child-Pugh class (HR = 4.3, P = 0.001), and portal vein invasion (HR = 6.45, P < 0.001) were independent factors associated with patient survival after TACE.
CONCLUSION: TACE is safe and effective in improving the survival of patients with nonresectable combined HCC-cholangiocarcinoma. Tumor vascularity is highly associated with tumor response.

Abstract
Two randomized controlled trials identified that transcatheter arterial chemoembolization (TACE) for hepatocellular carcinoma (HCC) shows a significant survival benefit compared with controls, after a long-term controversy. Thus, TACE is the current standard of care for patients presenting with multinodular HCC. Monitoring tumor response to TACE is part of the clinical management of HCC patients. Imaging, including ultrasonography, computed tomography and magnetic resonance imaging, has an important role in assessing therapeutic effects earlier and more objectively. Imaging assessment needs to detect not only a reduction in overall tumor load but also a reduction in viable tumor. Here, we give an overview of the current status of the imaging assessment of HCC response to TACE.

Abstract
OBJECTIVE Although hepatocellular carcinoma (HCC) demonstrates characteristic hypervascularity, some HCCs have a hypovascular pattern on computed tomography (CT). Cytokeratin 19 (CK19) is a marker for the biliary phenotype reflecting a poor prognosis. We assessed the prognostic implications of tumor vascularity and its association with CK19 expression in HCC. METHODS Patients that underwent surgical resection for HCC were included. Tumor vascularity was evaluated according to the arterial enhancement patterns on CT scans and CK19 expression was evaluated by using tissue microarray methods. RESULTS One hundred and forty patients were included. Their median follow-up duration was 55.0 months, and 92 (65.7%) patients had tumor recurrence. Forty-five patients (30.6%) had hypovascular HCC at the time of diagnosis, and they showed a significantly higher CK19 expression rate (32.5% vs. 8.2%, P = 0.001) and earlier recurrence rate within 6 months (hazard ratio (HR), 2.301; P = 0.025) compared to the patients with hypervascular HCCs. Hypovascularity (HR, 1.694; P = 0.045) was an independent risk factor for short overall survival. CONCLUSIONS Hypovascular HCCs were associated with early recurrence and short overall survival, and CK19 was more frequently expressed in hypovascular HCC than in hypervascular tumors. Therefore, tumor vascularity on CT images might be utilized in determining the prognosis of patients with HCCs.

Abstract
PURPOSE To evaluate the factors associated with tumor response and survival after chemoembolization in 362 patients with hepatocellular carcinoma (HCC). MATERIALS AND METHODS Between January 2006 and August 2006, 362 patients who underwent chemoembolization for unresectable HCC were evaluated. The endpoints were tumor response and patient survival. Factors associated with tumor response were evaluated using multivariate logistic regression analysis. Factors associated with patient survival were evaluated using multivariate Cox regression analysis. RESULTS After chemoembolization, 69% of the study patients showed a tumor response. On multivariate analysis, tumor size (centimeter) (odds ratio [OR] 2.85, P = .002), tumor number (OR 4.58, P < .001), tumor vascularity (OR 11.97, P < .001), and portal vein invasion (OR 4.24, P < .001) were significant factors for tumor response. The median survival was 23 months. On multivariate analysis, Child-Pugh class (hazard ratio [HR] 2.43, P < .001), maximal tumor size (HR 1.66, P = .002), tumor vascularity (HR 2.13, P = .001), portal vein invasion (HR 2.39, P < .001), tumor number (HR, 1.92, P < .001), and alpha fetoprotein (AFP) value (HR 1.54, P = .003) were significant factors associated with patient survival after chemoembolization. CONCLUSIONS Tumor size, tumor vascularity, tumor number, and portal vein invasion are significant independent predictors of tumor response after chemoembolization in patients with unresectable HCC. Child-Pugh class B or C, large tumor size (≥ 4 cm), multiple tumors (five or more), portal vein invasion, and a high AFP value (> 83 ng/mL) indicated poor prognosis for overall patient survival after chemoembolization.

Abstract
BACKGROUND Hepatocellular carcinoma (HCC) is a common malignant tumor in China, and early diagnosis is critical for patient outcome. In patients with HCC, it is mostly based on liver cirrhosis, developing from benign regenerative nodules and dysplastic nodules to HCC lesions, and a better understanding of its vascular supply and the hemodynamic changes may lead to early tumor detection. Angiogenesis is essential for the growth of primary and metastatic tumors due to changes in vascular perfusion, blood volume and permeability. These hemodynamic and physiological properties can be measured serially using functional computed tomography perfusion (CTP) imaging and can be used to assess the growth of HCC. This study aimed to clarify the physiological characteristics of tumor angiogenesis in cirrhotic liver disease by this fast imaging method. METHODS CTP was performed in 30 volunteers without liver disease (control subjects) and 49 patients with liver disease (experimental subjects: 27 with HCC and 22 with cirrhosis). All subjects were also evaluated by physical examination, laboratory screening and Doppler ultrasonography of the liver. The diagnosis of HCC was made according to the EASL criteria. All patients underwent contrast-enhanced ultrasonography, pre- and post-contrast triple-phase CT and CTP study. A mathematical deconvolution model was applied to provide hepatic blood flow (HBF), hepatic blood volume (HBV), mean transit time (MTT), permeability of capillary vessel surface (PS), hepatic arterial index (HAI), hepatic arterial perfusion (HAP) and hepatic portal perfusion (HPP) data. The Mann-Whitney U test was used to determine differences in perfusion parameters between the background cirrhotic liver parenchyma and HCC and between the cirrhotic liver parenchyma with HCC and that without HCC. RESULTS In normal liver, the HAP/HVP ratio was about 1/4. HCC had significantly higher HAP and HAI and lower HPP than background liver parenchyma adjacent to the HCC. The value of HBF at the tumor rim was significantly higher than that in the controls. HBF, HBV, HAI, HAP and HPP, but not MTT and PS, were significantly higher in the cirrhotic liver parenchyma involved with HCC than those of the controls. Perfusion parameters were not significantly different between the controls and the cirrhotic liver parenchyma not involved with HCC. CONCLUSIONS CTP can clearly distinguish tumor from cirrhotic liver parenchyma and controls and can provide quantitative information about tumor-related angiogenesis, which can be used to assess tumor vascularization in cirrhotic liver disease.

Abstract
AIM To evaluate the clinical outcome and the survival benefits of transarterial chemoembolization (TACE) for unresectable intrahepatic cholangiocarcinoma (ICC) compared with supportive therapy. MATERIALS AND METHODS From January 1996 to April 2009, a total of 155 patients with unresectable ICC met the entry criteria and underwent TACE (72 patients) or supportive treatment (83 patients). Their survival was the primary end point. RESULTS The baseline patients and tumour characteristics were well-balanced in the two groups. The median number of sessions per patient was 2.5 (range 1-17 sessions) in the TACE group. After TACE, the incidence of significant (≥ grade 3) haematological and non-haematological toxicities was 13 and 24%, respectively, and no patients died within 30 days following TACE. The objective tumour regression (≥ partial response) was achieved in 23% of the patients in the TACE group. The Kaplan-Meier survival analysis showed that the survival period was significantly longer in the TACE group (median 12.2 months) than in the symptomatic treatment (median 3.3 months) group (p < 0.001). CONCLUSIONS TACE is safe and offers greater survival benefits than supportive treatment for the palliative treatment of unresectable ICC.

Abstract
Imaging studies play a crucial role in the diagnosis and staging of hepatocellular carcinoma (HCC). Yet, assessment of tumor response is another important goal for imaging. The imaging techniques most commonly used for assessing tumor response include computed tomography and magnetic resonance imaging. Imaging modalities and imaging criteria vary according to the treatment (surgical resection and transplantation or nonsurgical treatments such as transarterial chemoembolization, radiofrequency ablation, and molecular targeted therapy). Efficacy of nonsurgical treatments for malignancy is usually evaluated with RECIST criteria. These criteria, based on tumor shrinkage, are often inappropriate in HCCs. The response criteria should take into account tumor necrosis induced by treatment. Today, tumor necrosis is estimated by a disappearance of hypervascularization on contrast-enhanced imaging. New tools such as functional imaging (perfusion imaging, diffusion-weighted MR imaging) could be of major importance. In this article, we present a summary of the most recent information on the role of imaging in assessing treatment efficacy in HCCs.

Abstract
AIM: To elucidate the relationship between the microvessel count (MVC) by CD34 analyzed by immunohistochemical method and prognosis in hepatocellular carcinoma (HCC) patients who underwent hepatectomy based on our preliminary study.
METHODS: We examined relationships between MVC and clinicopathological factors in 128 HCC patients. The modified Japan Integrated Staging score (mJIS) was applied to examine subsets of HCC patients.
RESULTS: Median MVC was 178/mm2, which was used as a cut-off value. MVC was not significantly associated with any clinicopathologic factors or postoperative recurrent rate. Lower MVC was associated with poor disease-free and overall survivals by univariate analysis (P = 0.039 and P = 0.087, respectively) and lower MVC represented an independent poor prognostic factor in disease-free survival by Cox’s multivariate analysis (risk ratio, 1.64; P = 0.024), in addition to tumor size, vascular invasion, macroscopic finding and hepatic dysfunction. Significant differences in disease-free and overall survivals by MVC were observed in HCC patients with mJIS 2 (P = 0.046 and P = 0.0014, respectively), but not in those with other scores.
CONCLUSION: Tumor MVC appears to offer a useful prognostic marker of HCC patient survival, particularly in HCC patients with mJIS 2.

Abstract
AIM To elucidate the pre-treatment clinical and imaging findings affecting the tumor response to the transcatheter treatment of unresectable hepatocellular carcinoma (HCC). METHODS Two hundred cirrhotic patients with HCC received a total of 425 transcatheter treatments. The tumor response was evaluated by helical CT and a massive necrosis (MN) was defined as a necrosis > 90%. Twenty-five clinical and imaging variables were analyzed: uninodular/multinodular HCC, unilobar/bilobar, tumor capsula, hypervascular lesion, portal vein thrombosis, portal hypertension, ascites, platelets count, aspartate transaminases/alanine transaminases (AST/ALT), alfa-fetoprotein (AFP) > 100, AFP > 400, serum creatinine, virus hepatitis C (VHC) cirrhosis, performance status, age, Okuda stage, Child-Pugg stage, sex, CLIP (Cancer of the Liver Italian Program) score, serum bilirubin, constitutional syndrome, serum albumine, prothrombin activity, BCLC (Barcelona Clinic Liver Cancer) stage. Prognostic factors of response were subjected to univariate analysis and thereafter, when significant, to the multivariate analyses. RESULTS On imaging analysis, complete response was obtained in 60 (30%) patients, necrosis > 90% in 38 (19%) patients, necrosis > 50% in 44 (22%) patients, and necrosis < 50% in 58 (29%) patients. Ninety-eight (49%) of the 200 patients were considered to have a MN. In univariate analysis, significant variables (P < 0.01) were: uninodular tumor, unilobar, tumor size 2-6 cm, CLIP score < 2, absence of constitutional syndrome, and BCLC stage < 2. In a multivariate analysis, the variables reaching statistical significance were: presence of tumor capsule (P < 0.0001), tumor size 2-6 cm (P < 0.03), CLIP score < 2 (P < 0.006), and absence of constitutional syndrome (P < 0.03). Kaplan-Mayer cumulative survival at 12 mo was 80% at 24 mo was 56%. MN was associated with a longer survival (P < 0.0001). CONCLUSION MN after transcatheter treatment is more common in the presence of tumor capsule, maximum diameter of the main lesion between 2 and 6 cm, CLIP score < 2 and absence of constitutional syndrome. The ability to predict which patients will respond to transcatheter treatment may be useful in the clinical decision-making process, and in stratifying the randomization of patients in clinical trials.

Abstract
PurposeThe aims of the present study were to assess the prevalence of depressive symptoms at diagnosis, test the association between depressive symptoms and survival, and preliminarily test a mediational model of depression, immunity, and survival in patients with hepatobiliary carcinoma (HBC).Patients and MethodsOne hundred one patients diagnosed with HBC were prospectively studied. Depressive symptoms were measured at diagnosis using the Center for Epidemiological Studies Depression Scale (CES-D). Sociodemographic and disease-specific data were gathered from the patients' charts. In a subsample of patients, stress; alcohol, tobacco, and drug use; sleep quality; physical activity; social support; natural killer (NK) cell number and cytotoxicity; and plasma levels of interleukin (IL) -4, IL-5, tumor necrosis factor alpha, and interferon gamma were measured. Survival was measured from date of diagnosis to death.ResultsAt diagnosis, 37% of patients reported a CES-D score of ≥ 16 (clinical range). Using Cox regression analysis, sociodemographic and disease-specific variables and CES-D score significantly predicted survival (Breslow χ2= 32.4, P = .006). Only vascular invasion (P = .001) and CES-D score ≥ 16 (P = .03) were significant predictors. In a subsample of 23 patients, patients who reported a CES-D score of ≥ 16 were found to have significantly lower NK cell numbers than patients who reported a CES-D score of less than 16 (F1,21= 9.39, P = .003). A robust trend was found in which NK cell number was associated with survival. A mediational model linking depressive symptoms and survival, with NK cell number as a mediator, was preliminarily supported.ConclusionSecondary to the high prevalence of depressive symptoms and impact on survival, psychological and pharmacologic interventions should be designed and implemented in patients diagnosed with HBC.

Abstract
CT commonly is indicated for the evaluation of suspected hepatic and biliary pathology. The recent introduction of multidetector CT (MDCT) provides unique capabilities that are valuable especially in hepatic volume acquisitions, combining short scan times, narrow collimation, and the ability to obtain multiphase data. These features result in improved lesion detection and characterization. Concomitant advances in computer software programs have made three-dimensional applications practical for a range of hepatic image analyses and displays. This article discusses the specific areas of hepatic and biliary pathology where MDCT has a significant diagnostic impact.

Abstract
Improved therapeutic options for hepatocellular carcinoma and metastatic disease place greater demands on diagnostic and surveillance tests for liver disease. Existing diagnostic imaging techniques provide limited evaluation of tissue characteristics beyond morphology; perfusion imaging of the liver has potential to improve this shortcoming. The ability to resolve hepatic arterial and portal venous components of blood flow on a global and regional basis constitutes the primary goal of liver perfusion imaging. Earlier detection of primary and metastatic hepatic malignancies and cirrhosis may be possible on the basis of relative increases in hepatic arterial blood flow associated with these diseases. To date, liver flow scintigraphy and flow quantification at Doppler ultrasonography have focused on characterization of global abnormalities. Computed tomography (CT) and magnetic resonance (MR) imaging can provide regional and global parameters, a critical goal for tumor surveillance. Several challenges remain: reduced radiation doses associated with CT perfusion imaging, improved spatial and temporal resolution at MR imaging, accurate quantification of tissue contrast material at MR imaging, and validation of parameters obtained from fitting enhancement curves to biokinetic models, applicable to all perfusion methods. Continued progress in this new field of liver imaging may have profound implications for large patient groups at risk for liver disease.

Abstract
The ability of x-ray computed tomography (CT) to detect and characterize liver lesions has been one of the most studied issues in radiology during the past 20 years. Technological advances, combined with increased knowledge about the pathophysiological characteristics of these tumors, have dramatically increased the ability to detect and characterize large hepatocellular carcinomas (HCCs). Nonetheless, detection and characterization of early and small HCC lesions remains a difficult task. We review the imaging appearances of HCC on CT and discuss the sensitivity and specificity of computed tomographic imaging in screening patients with cirrhosis for HCC.

Abstract
AIM: To investigate the expression level of plasma vascular endothelial growth factor (P-VEGF) in patients with hepatocellular carcinoma (HCC) and its relationship with the clinicopathologic characteristics, and to examine the changes of P-VEGF in the course of transcatheter arterial chemoembolization (TACE).
METHODS: Peripheral blood samples were taken from 45 HCC patients before and 1, 3, 7 d, and 1 mo after TACE. Plasma VEGF level was measured with the quantitative sandwich enzyme-linked immunosorbent assay (ELISA). Twenty patients with benign liver lesions and 17 healthy control subjects were also included in this study.
RESULTS: Plasma VEGF levels in HCC patients were significantly elevated as compared to those in patients with benign liver lesions (P = 0.006) and in the normal controls (P = 0.003). Significant differences were observed when P-VEGF was categorized by tumor size (P = 0.006), portal vein thrombosis (P = 0.011), distant metastasis (P = 0.017), arterial-portal vein shunting (P = 0.026), and International Union Against Cancer (UICC) TNM stage (P = 0.044). There was no correlation between plasma level of VEGF and the level of alpha fetoprotein (α-FP) (r = 0.068, P = 0.658) and weakly correlated with the number of platelets (r = 0.312, P = 0.038). P-VEGF levels increased significantly and reached the peak value on the first day after TACE, and then decreased gradually. The change rate of P-VEGF concentration (one month post-TACE/pre-TACE × 100%) was correlated with the retention rate of lipiodol oil (rs = 0.494, P = 0.001) and the tumor volume change (rs = 0.340, P = 0.034). The patients who achieved a partial or complete response to TACE therapy showed significantly less pre-treatment P-VEGF than those nonresponders (P = 0.025). A high pre-therapeutic P-VEGF level was associated with poor response to treatment (P = 0.018).
CONCLUSION: A high pre-treatment P-VEGF level is a useful marker for tumor progression, especially for vascular invasion. TACE increases the level of P-VEGF only temporarily which may be associated with tumor ischemia. P-VEGF may be useful in predicting treatment response, monitoring disease course after TACE and judging the effect of different TACE regimens.

Abstract
AIM: To work out an individualized lipiodol dose in transcatheter arterial chemoembolization (TACE) for large hepatocellular carcinoma (HCC) according to its blood supply evaluated by CT.
METHODS: One hundred patients with large HCC (more than 8 cm in diameter) were studied by multidetector helical CT. Patterns of blood supply of HCC were divided into sufficient blood supply, poor blood supply, mixed blood supply and arteriovenous (A-V) shunt. The dose of ultra-fluid lipiodol was determined by diameter and blood supply type of HCC. Patients were divided into two groups (50 cases each): lipiodol perfusion group and iodized oil perfusion group according to tumor diameter and the blood supply type of tumor.
RESULTS: The confirmation and effective rates were 82%, 84% in the first group and 36%, 46% in the second group (P < 0.01).
CONCLUSION: A relatively individualized lipiodol dose may be determined according to the blood supply pattern and the tumor diameter by CT imaging.

Abstract
RATIONALE AND OBJECTIVES To apply perfusion computed tomography (CT) technique to variable malignant liver tumors, and to define the usefulness of quantitative color mapping. MATERIALS AND METHODS Perfusion CT images were created for 36 malignant liver tumors in 28 patients (age, 66.4 +/- 10.1 years; range, 48-85) with metastatic liver tumors (n = 17; nine colorectal carcinomas, eight other malignant tumors) and hepatocellular carcinomas (n = 11). A single-slice dynamic CT was performed after an intravenous bolus injection of 40 mL of contrast material (320 mgI/mL) with 8 mL/sec. The parameters were calculated pixel-by-pixel using maximum slope method, and quantitative maps of arterial and portal perfusion were created. In four patients who underwent transcatheter arterial chemoembolization, perfusion CT was performed before and after transcatheter arterial chemoembolization. RESULTS In all patients, liver tumors were shown as hypervascular lesions on arterial perfusion CT. The average arterial perfusion value of the metastatic tumors from the colorectal carcinomas was 0.67 +/- 0.33 mL/min/mL, and that of hepatocellular carcinomas was 0.94 +/- 0.26 mL/min/mL (P = .03). The other metastatic tumors from various primary tumors showed a wide range (0.19-1.45 mL/min/mL) of arterial perfusion. Arterial perfusion of the liver tumors was obviously decreased after successful transcatheter arterial chemoembolization. In 12 of 15 tumors, in which portal perfusion CT images could be created, region-of-interest analysis showed no portal perfusion in the tumors. In two cases, decreased portal perfusion in the segments, which malignant tumors involved, was demonstrated. CONCLUSION Perfusion CT can provide quantitative information about arterial and portal perfusion of liver tumors, combined with good anatomic detail in one image. This technique has a potential to evaluate the angiogenesis of liver tumors, to show secondary changes in perfusion, such as decreased portal perfusion in apparently normal liver adjacent to metastases, and to monitor the therapeutic response in vivo.

Abstract
BACKGROUND The authors used computed tomography (CT) scans to correlate the changes in tumor vascularity, necrosis, and size with response and survival after transcatheter arterial chemoembolization (TACE) in patients with advanced, unresectable, hepatocellular carcinoma (HCC). METHODS The authors studied 72 patients with biopsy-proven, unresectable HCC and focused on 186 individual tumor masses. A baseline, multiphase, helical CT was performed and at least three follow-up CT scans were performed after treatment by TACE. Tumors were classified as hypervascular or hypovascular and patients were classified as responders or nonresponders based on CT evidence of altered tumor size, tumor necrosis, and the appearance of new tumors. A new scoring system was used to monitor patient response to TACE. RESULTS Thirty-eight patients were responders and 34 were nonresponders. Patient survival was significantly increased (P = 0.009) in patients who were hypervascular responders. Survival also was increased in hypervascular nonresponders compared with hypovascular nonresponders (P = 0.008) and in hypovascular responders compared with hypovascular nonresponders (P = 0.002). Response to chemoembolization was found to be significantly (P = 0.02) and inversely proportional to tumor size, but the number of tumor foci in an individual patient was not predictive. CONCLUSIONS TACE appears to result in improved survival among HCC patients with hypervascular tumors who responded to therapy. However, even patients classified by CT as hypervascular nonresponders and hypovascular responders have improved survival.

Abstract
AIM: To establish an ideal implantable rat liver tumor model for interventional therapy study and examine its angiographic signs and MRI, CT features before and after embolization.
METHODS: Forty male Wistar rats were implanted with Walker-256 tumor in the left lateral lobe of liver. Digital subtraction angiography (DSA) and transarterial chemoembolization were performed on day 14 after implantation. Native computer tomography (CT, n = 8) and native magnetic resonance (MR, n = 40) were performed between the day 8 and day 21 after implantation. The radiological morphological characteristics were correlated with histological findings.
RESULTS: Successful implantation was achieved in all forty rats, which was confirmed by CT and MRI. MR allowed tumor visualization from day 8 while CT from day 11 after implantation. The tumors were hypodensity on CT, hypointense on MR T1-weighted and hyperintense on T2-weighted. The model closely resembled human hepatocarcinoma in growth pattern and the lesions were rich in vasculature on angiography and got its filling mainly from the hepatic artery. Before therapy, tumor size was 211.9 ± 48.7 mm3. No ascites, satellite liver nodules or lung metastasis were found. One week after therapy, tumor size was 963.6 ± 214.8 mm3 in the control group and 356.5 ± 78.4 mm3 in TACE group. Ascites (4/40), satellite liver nodules (7/40) or lung metastasis (3/40) could be seen on day 21.
CONCLUSION: Walker-256 tumor rat model is suitable for the interventional experiment. CT and MRI are helpful in animal optioning and evaluating experimental results.

Abstract
AIM To evaluate the role and limitation of fast multiplanar spoiled gradient-recalled (FMPSPGR) MR dynamic contrast scanning in the follow-up of patients with HCC treated by transarterial chemoembolization (TACE). METHODS Twenty-two patients with 24 HCC lesions confirmed by biopsy or surgical resection underwent MR imaging in 4-9wks after TACE with a superconducting 1.5 T MR scanner, including SE T(1)WI, T(2)WI and FMPSPGR dynamic contrast scanning. The signal intensities of all lesions on SE T(1)WI,T(2)WI and the enhancement patterns on FMPSPGR dynamic contrast scanning were observed, and the comparison was made between MRI findings and pathological results in all the cases. RESULTS Of the 24 lesions, the signal intensities were various on SE T(1)WI and T(2)WI. On T(1)WI, 13 lesions appeared as hyperintense, 4 lesions were isointense and the other 7 lesions were hypointensese. Histologically, hyperintense lesions showed on T(1)WI were viable tumor or hemorrhage; isointensities were coagulative necrosis or inflammatory infiltration; hypointensities were tumor, liquified necrosis, coagulative necrosis or inflammatory infiltration. On T(2)WI, 15 lesions appeared as hyperintense, 3 lesions were isointense and the other 6 lesions were hypointensese. Hyperintense lesions showed on T(2)WI were residuals of viable tumor, hemorrhage, liquefied necrosis or inflammatory infiltration; isointense lesions were residuals of viable tumor or inflammatory infiltration; hypointense lesions were coagulative necrosis. On FMPSPGR dynamic contrast scanning, 18 of the 24 lesions enhanced on early-phase dynamic scanning corresponding to residuals of viable tumor and the other 6 lesions had no enhancement at this phase because complete necrosis were seen in the histologic examination. On delayed-phase dynamic scanning, 6 lesions had permanent enhancement appeared as inhomogeneous hyperintensity and both residuals of viable tumor and inflammatory infiltration were found by histologic examination. 18 lesions were hypointense at this phase and 8 of them coexisted with peripheral ring-like enhancement of the lesions resulting from viable tumors or inflammatory infiltration. CONCLUSION FMPSPGR MR dynamic contrast scanning can reflect the pathologic changes of HCC treated by TACE. Especially, early-phase dynamic scanning can evaluate accurately residuals of viable tumor and necrosis in HCC lesions. FMPSPGR dynamic contrast scanning is useful in the follow-up of patients with HCC treated by TACE combined with SE T(1)WI and T(2)WI, but it is difficult to differentiate peripheral viable tumors from inflammatory infiltration.

Abstract
AIM: To conduct a randomized trial to evaluate the role of using high-dose iodized oil transcatheter arterial chemoembolization(TACE) in the treatment of large hepatocellular carcinoma (HCC).
METHODS: From January 1993 to June 1998, 473 patients with unresectable hepatocellular carcinoma were divided into two groups: 216 patients in group A received more than 20mL iodized oil during the first TACE treatment; 257 patients in group B received 5-15 mL iodized oil in the same way. The Child’s classification and ICG-R15 for evaluating the liver function of the patients were done before the treatment. During the TACE procedure the catheters was inserted into the target artery selectively and the tumor vessels were demonstrated with contrast medium in the hepatic angiography. The anticancer drug mixed with iodized oil (Lipiodol) were Epirubicin and Mitomycin. In group A, 112 cases received 20-29 mL Lipiodol in the first procedure, 85 cases 30-39 mL, 19 cases more than 40 mL. The largest dose was 53 mL and the average dose was 28.3 mL. In group B, 119 cases received 5-10 mL Lipiodol, 138 cases received 11-15 mL, and the average dose was 11.8 mL.
RESULTS: High-dose Lipiodol chemoembolization caused tolerable side effects and a little hurt to the liver function in the patients with Child grade A or ICG-R15 < 20. But the patients with child grade B or ICG-R15 > 20 had higher risk of liver failure after high-dose TACE. More type I and type II lipiodol accumulations in CT scan after 4 weeks of TACE were seen in the group A patients than those in the group B patients (P < 0.01). The resection rate and complete tumor necrosis rate in group A were higher than those of group B (P < 0.05). The 1-,2-,3-year survival rates of group A patients with Child grade A were 79.2%, 51.8% and 34.9%, respectively, better than those of group B (P < 0.001).
CONCLUSION: High-dose Lipiodol can result in more complete tumor necrosis by blocking both arteries and small portal vein of the tumor. High-dose TACE for treatment of large and hypervascular hepatocellular carcinoma is practically acceptable with the better effect than the routine dose. For the patients with large and hypervascular tumor of Child grade A liver function or ICG-R15 less than 20%, oily chemoembolization with 20-40 mL Lipiodol is recommended.
