Objective
To evaluate the safety and efficacy of transcatheter arterial chemoembolization (TACE) in patients with infiltrative hepatocellular carcinoma (HCC) and to identify the prognostic factors associated with patient survival.Materials and Methods
Fifty two patients who underwent TACE for infiltrative HCC were evaluated between 2007 and 2010. The maximum diameter of the tumors ranged from 7 cm to 22 cm (median 15 cm). Of 46 infiltrative HCC patients with portal vein tumor thrombosis, 32 patients received adjuvant radiation therapy for portal vein tumor thrombosis after TACE.Results
The tumor response by European Association for the Study of the Liver criteria was partial in 18%, stable in 47%, and progressive in 35% of the patients. The median survival time was 5.7 months (Kaplan-Meier analysis). The survival rates were 48% at six months, 25% at one year, and 12% at two years. In the multivariable Cox regression analysis, Child-Pugh class (p = 0.02), adjuvant radiotherapy (p = 0.003) and tumor response after TACE (p = 0.004) were significant factors associated with patient survival. Major complications occurred in nine patients. The major complication rate was significantly higher in patients with Child-Pugh B than in patients with Child-Pugh A (p = 0.049, χ2 test).Conclusion
Transcatheter arterial chemoembolization can be a safe treatment option in infiltrative HCC patients with Child Pugh class A. Child Pugh class A, radiotherapy for portal vein tumor thrombosis after TACE and tumor response are good prognostic factors for an increased survival after TACE in patients with infiltrative HCCs. 相似文献2.

Objectives
To compare estimated remnant liver volume (ERLV) ratios among the major main portal vein (MPV) variants.Methods
Eighty-five potential donors underwent multidetector CT examination. Arterial, portal and hepatic venous phase images were obtained. CT volumetric measurements were performed by using summation-of-area method. MPV variants were classified into three groups. In type 1 (group 1), the MPV branches into the right portal vein (RPV) and the left portal vein (LPV). In type 2 (group 2), the MPV trifurcates into the right anterior portal vein (RAPV), right posterior portal vein (RPPV) and LPV. In type 3 (group 3), the RPPV arises from the MPV as a first branch, and the RAPV emerges directly from the LPV.Results
No differences were observed between groups 1 and 2 with respect to ERLV ratios. However, significant differences were discovered between groups 1 and 3 and between groups 2 and 3 (p < 0.001 and p < 0.05, respectively).Conclusions
The ERLV proportions in the donors with a type 3 MPV variation were significantly lower than those in the donors with type 1 and type 2 MPV variations and six (31.6%) donors in group 3 presented an ERLV percentage below 30% of the total liver volume. 相似文献3.

Objective
To study the role of DWI in the differentiation between bland and malignant portal vein thrombus in HCC patients.Materials and methods
Prospective study carried on 74 HCC patients with associated portal vein thrombus. Dynamic MRI examination and Diffusion imaging were performed for all patients. ADC values and ratios “ratio between the ADC value of HCC and ADC value of the thrombus” were calculated. We use at least two of the following criteria including the size of HCC more than 5?cm, the distance between the portal vein thrombus and the HCC less than 2?cm and the presence of enhancement within the thrombus, as a standard of reference to determine the nature of the thrombus.Results
We studied 74 patients; 55 patients diagnosed with malignant portal vein thrombosis and 19 patients diagnosed with bland portal vein thrombosis. We found that the ADC ratio with a cutoff value of 1.2 helped in discriminating the nature of the thrombus with 98% sensitivity and 70% specificity. There was no statistically significant difference in the ADC values of the benign and malignant thrombus.Conclusion
DWI can determine the nature of the portal vein thrombus by measuring the ADC ratio between the tumour and the thrombus. 相似文献4.

Objective
To assess the feasibility and safety of polyvinyl alcohol (PVA) embolization adjuvant to transarterial oily chemoembolization (P-TACE) in advanced hepatocellular carcinoma (HCC) with arterioportal shunts (APS).Materials and Methods
Nineteen patients who underwent PVA embolization for APS before a routine chemoembolization (TACE) procedure were retrospectively reviewed. 10 of these 19 patients underwent follow-up TACE or P-TACE after P-TACE (Group A), but nine patients underwent only initial P-TACE because of progression of HCC and/or underlying liver cirrhosis (Group B). Hepatic function tests, APS grades, and portal flow directions were evaluated before and after P-TACE sessions. Complications after procedures and survival days were also evaluated.Results
In group A, APS grade was improved in eight patients and five of six patients with hepatofugal flow showed restored hepatopetal flow postoperatively. No immediate complication was developed in either group. Transient hepatic insufficiency developed in eight (42.1%) of 19 patients after P-TACE, and seven (87.5%) of these eight recovered within two weeks under conservative care. The mean and median survival time all study subjects was 280 days and 162 days.Conclusion
P-TACE is feasible and safe in advanced HCC patients with APS. 相似文献5.

Objective
To evaluate the pattern of right gastric venous drainage by use of digital subtraction angiography.Materials and Methods
A series of 100 consecutive patients who underwent right gastric arteriography during transcatheter arterial chemoembolization for hepatocellular carcinoma were included in this study. Angiographic findings were retrospectively analyzed with respect to the presence or absence of the right and aberrant gastric veins, multiplicity of draining veins, aberrant right gastric venous drainage sites, and the termination pattern of aberrant right gastric veins (ARGVs). We also compared the relative size of the right and left gastric veins.Results
A total of 49 patients collectively had 66 ARGVs. The common drainage sites for the ARGVs included the hepatic segment IV (n = 35) and segment I (n = 15). The termination pattern of ARGV could be classified into 4 different types. The most common type was termination as a superficial parenchymal blush formation in small areas without demonstrable portal branches. A statistically significant difference was found for the dominancy of the right gastric vein in gastric venous drainage between the two groups with or without ARGV (p < 0.05, Fisher''s exact test). In the group of patients without ARGV (n = 51), the right gastric vein was equal to (n = 9) or larger than (n = 17) the left gastric vein in 26 patients (26 of 51, 51%).Conclusion
The incidence of ARGV is higher than expected with four distinct types in its termination pattern. The right gastric vein may play a dominant role in gastric venous drainage. 相似文献6.

Objective
The purpose of this study was to determine the utility of preoperative CT in predicting early recurrence of hepatocellular carcinoma after partial hepatic resection.Materials and Methods
Preoperative three-phase helical CT scans in 53 patients with hepatocellular carcinoma were retrospectively reviewed by two radiologists. In 27 patients (group I), HCC had recurred within six months, while 26 (group II) had remained disease free for at least two years. In each group, preoperative CT findings were evaluated in each group for the tumor size and number, the presence or absence of capsule, distinctness of tumor margin, perinodular extension, and the presence or absence of portal vein thrombosis.Results
In group I, a tumor capsule of tumor was seen in five of 27 patients (19%), and in group II, in 16 of 26 (62%) (p = .001). The tumor margin was distinct in eight patients (30%) in group I and in 20 (77%) in group II (p = .001). Multiple tumors, perinodular extension, and portal vein thrombosis were more frequently seen in group I but the differences were not statistically significant (p > .05). Tumor size was similar in each group (p > .05).Conclusion
Preoperative CT findings that may help predict the early recurrence of hepatocellular carcinoma after surgical resection are an absence of capsule of tumors and an indistinct margin. Reference to these findings during preoperative CT can guide clinicians in their choice of treatment. 相似文献7.

Objective
To compare gadoxetic acid injection rates of 0.5 mL/s and 1 mL/s for hepatic arterial-phase magnetic resonance (MR) imaging.Materials and Methods
In this prospective study, 101 consecutive patients with suspected focal liver lesions were included and randomly divided into two groups. Each group underwent dynamic liver MR imaging using a 3.0-T scanner after an intravenous injection of gadoxetic acid at rates of either 0.5 mL/s (n = 50) or 1 mL/s (n = 51). Arterial phase images were analyzed after blinding the injection rates. The signal-to-noise ratios (SNRs) of the liver, aorta, portal vein, hepatic vein, spleen, and pancreas were measured. The contrast-to-noise ratios (CNRs) of the hepatocellular carcinomas (HCC) were calculated. Finally, two experienced radiologists were independently asked to identify, if any, HCCs in the liver on the images and score the image quality in terms of the presence of artifacts and the proper enhancement of the liver, aorta, portal vein, hepatic vein, hepatic artery, spleen, pancreas, and kidney.Results
The SNRs were not significantly different between the groups (p = 0.233-0.965). The CNRs of the HCCs were not significantly different (p = 0.597). The sensitivity for HCC detection and the image quality scores were not significantly different between the two injection rates (p = 0.082-1.000).Conclusion
Image quality and sensitivity for hepatic HCCs of arterial-phase gadoxetic acid-enhanced MR were not significantly improved by reducing the contrast injection rate to 0.5 mL/s compared with 1 mL/s. 相似文献8.

Objective
While the prognostic factors of survival for patients with hepatocellular carcinoma (HCC) who underwent transarterial chemoembolization (TACE) are well known, the clinical significance of performing selective TACE for HCC patients has not been clearly documented. We tried to analyze the potential factors of disease-free survival for these patients, including the performance of selective TACE.Materials and Methods
A total of 151 patients with HCC who underwent TACE were retrospectively analyzed for their disease-free survival (a median follow-up of 23 months, range: 1-88 months). Univariate and multivariate analyses were performed for 20 potential factors by using the Cox proportional hazard model, including 19 baseline factors and one procedure-related factor (conventional versus selective TACE). The parameters that proved to be significant on the univariate analysis were subsequently tested with the multivariate model.Results
Conventional or selective TACE was performed for 40 and 111 patients, respectively. Univariate and multivariate analyses revealed that tumor multiplicity, venous tumor thrombosis and selective TACE were the only three independent significant prognostic factors of disease-free survival (p = 0.002, 0.015 and 0.019, respectively).Conclusion
In our study, selective TACE was a favorable prognostic factor for the disease-free survival of patients with HCC who underwent TACE. 相似文献9.

Objective
The conventional method of dividing hepatic segment 2 (S2) and 3 (S3) is subjective and CT interpretation is unclear. The purpose of our study was to test the validity of our hypothesis that the actual plane dividing S2 and S3 is a vertical plane of equal distance from the S2 and S3 portal veins in clinical situations.Materials and Methods
We prospectively performed thin-section iodized-oil CT immediately after segmental chemoembolization of S2 or S3 in 27 consecutive patients and measured the angle of intersegmental plane on sagittal multiplanar reformation (MPR) images to verify its vertical nature. Our hypothetical plane dividing S2 and S3 is vertical and equidistant from the S2 and S3 portal veins (vertical method). To clinically validate this, we retrospectively collected 102 patients with small solitary hepatocellular carcinomas (HCC) on S2 or S3 the segmental location of which was confirmed angiographically. Two reviewers predicted the segmental location of each tumor at CT using the vertical method independently in blind trials. The agreement between CT interpretation and angiographic results was analyzed with Kappa values. We also compared the vertical method with the horizontal one.Results
In MPR images, the average angle of the intersegmental plane was slanted 15 degrees anteriorly from the vertical plane. In predicting the segmental location of small HCC with the vertical method, the Kappa value between CT interpretation and angiographic result was 0.838 for reviewer 1 and 0.756 for reviewer 2. Inter-observer agreement was 0.918. The vertical method was superior to the horizontal method for localization of HCC in the left lobe (p < 0.0001 for reviewers 1 and 2).Conclusion
The proposed vertical plane equidistant from S2 and S3 portal vein is simple to use and useful for dividing S2 and S3 of the liver. 相似文献10.

Objective
We assessed the outcomes of a simplified technique for the percutaneous placement of a hepatic artery port-catheter system for chemotherapy infusion in advanced hepatocellular carcinoma with portal vein invasion.Materials and Methods
From February 2003 to February 2008, percutaneous hepatic artery port-catheter insertion was performed in 122 patients who had hepatocellular carcinoma with portal vein invasion. The arterial access route was the common femoral artery. The tip of the catheter was wedged into the right gastroepiploic artery without an additional fixation device. A side hole was positioned at the distal common hepatic artery to allow the delivery of chemotherapeutic agents into the hepatic arteries. Coil embolization was performed only to redistribute to the hepatic arteries or to prevent the inadvertent delivery of chemotherapeutic agents into extrahepatic arteries. The port chamber was created at either the supra-inguinal or infra-inguinal region.Results
Technical success was achieved in all patients. Proper positioning of the side hole was checked before each scheduled chemotherapy session by port angiography. Catheter-related complications occurred in 19 patients (16%). Revision was achieved in 15 of 18 patients (83%).Conclusion
This simplified method demonstrates excellent technical feasibility, an acceptable range of complications, and is hence recommended for the management of advanced hepatocellular carcinoma with portal vein thrombosis. 相似文献11.

Purpose
To assess feasibility, safety, and preliminary efficacy of an irradiation portal vein stent for portal vein tumor thrombosis (PVTT) in patients with hepatocellular carcinoma (HCC).Materials and Methods
Between October 2012 and September 2015, 25 of 40 patients (mean age of 55.5 y) with PVTT caused by HCC were recruited for treatment with an irradiation portal vein stent (self-expandable stent loaded with iodine-125 seeds) at a single hospital. Liver function was classified as Child-Pugh class A in 15 patients (60%) and class B in 10 patients (40%). The Eastern Cooperative Oncology Group performance status score was 0 in 3 patients (12%), 1 in 13 patients (52%), and 2 in 9 patients (36%). Transarterial chemoembolization was performed after stent placement. Outcomes were measured in terms of technical success, complications, stent patency, and overall survival.Results
The technical success rate was 92.0% (23/25). No complications grade 3 or higher according to Common Terminology Criteria for Adverse Events were observed. Median stent patency period was 8.0 months (range, 0.6–30.0 months). Between 7 and 955 days after stent placement, 65 cycles of transarterial chemoembolization were performed with a mean of 2.8 cycles per patient. Median survival was 12.5 months (range, 0.6–35.7 months).Conclusions
Placement of an irradiation portal vein stent appears feasible and safe and may prolong the patency of the portal vein. It is a promising technique for combining recanalization of an occluded portal vein and brachytherapy. 相似文献12.

Objective
To assess the technical feasibility and local efficacy of biplane fluoroscopy plus US-guided percutaneous radiofrequency ablation (RFA) for viable hepatocellular carcinoma (HCC) around retained iodized oil after transcatheter arterial chemoembolization (TACE).Materials and Methods
Our prospective study was approved by our institutional review board and informed consent was obtained from all participating patients. For patients with viable HCC around retained iodized oil after TACE, biplane fluoroscopy plus US-guided RFA was performed. We evaluated the rate of technical success and major complications on a post-RFA CT examination and local tumor progression with a follow-up CT.Results
Among 40 consecutive patients, 19 were excluded due to one of the following reasons: poorly visible HCC on fluoroscopy (n = 13), high risk location (n = 2), RFA performed under monoplane fluoroscopy and US guidance (n = 2), and poorly identifiable new HCCs on US (n = 2). The remaining 21 patients with 21 viable HCCs were included. The size of total tumors ranged from 1.4 to 5.0 cm (mean: 3.2 cm) in the longest diameter. Technical success was achieved for all 21 HCCs, and major complications were observed in none of the patients. During the follow-up period (mean, 20.3 months; range, 6.5-29.9 months), local tumor progression was found in two patients (2/21, 9.5%). Distant intrahepatic metastasis developed in 76.2% (16/21) of patients.Conclusion
When retained iodized oil around the tumor after TACE hampers the targeting of the viable tumor for RFA, biplane fluoroscopy plus US-guided RFA may be performed owing to its technical feasibility and effective treatment for viable HCCs. 相似文献13.

Objective
To assess the technical feasibility and local efficacy of percutaneous radiofrequency ablation (RFA) combined with transcatheter arterial chemoembolization (TACE) for an intermediate-sized (3-5 cm in diameter) hepatocellular carcinoma (HCC) under the dual guidance of biplane fluoroscopy and ultrasonography (US).Materials and Methods
Patients with intermediate-sized HCCs were treated with percutaneous RFA combined with TACE. RFA was performed under the dual guidance of biplane fluoroscopy and US within 14 days after TACE. We evaluated the rate of major complications on immediate post-RFA CT images. Primary technique effectiveness rate was determined on one month follow-up CT images. The cumulative rate of local tumor progression was estimated with the use of Kaplan-Meier method.Results
Twenty-one consecutive patients with 21 HCCs (mean size: 3.6 cm; range: 3-4.5 cm) were included. After TACE (mean: 6.7 d; range: 1-14 d), 20 (95.2%) of 21 HCCs were visible on fluoroscopy and were ablated under dual guidance of biplane fluoroscopy and US. The other HCC that was poorly visible by fluoroscopy was ablated under US guidance alone. Major complications were observed in only one patient (pneumothorax). Primary technique effectiveness was achieved for all 21 HCCs in a single RFA session. Cumulative rates of local tumor progression were estimated as 9.5% and 19.0% at one and three years, respectively.Conclusion
RFA combined with TACE under dual guidance of biplane fluoroscopy and US is technically feasible and effective for intermediate-sized HCC treatment. 相似文献14.

PURPOSE: To evaluate the clinical usefulness of a saline flush technique in improving the imaging quality of 3-dimensional computed tomography portography (3D-CTP). METHODS: To evaluate liver metastases, 58 patients were divided into 2 groups undergoing 3D-CTP with or without a saline flush. The computed tomography (CT) values of the right portal vein (RPV), left portal vein (LPV), main portal vein (MPV), and right hepatic parenchyma (RHP) were assessed. Maximum intensity projection (MIP) 3D-CTP images were evaluated by vessel visualization. RESULTS: Higher mean CT attenuation values in the RPV, LPV, MPV, and RPV-RHP were observed in the saline flush group and were statistically significant (P = 0.04, P = 0.03, P = 0.01, and P = 0.04, respectively). The difference in imaging quality between 2 groups was statistically significant (P = 0.04). In segment VIII, the ability to depict the segmental branches was significantly higher when the saline flush technique was used (P = 0.03). CONCLUSIONS: The saline flush technique increases the CT attenuation values of the portal vein and the difference in values between the portal vein and the tissue around it and improves the MIP imaging quality of 3D-CTP. 相似文献

Purpose
To compare and evaluate images acquired with two different MR angiography (MRA) sequences, three‐dimensional (3D) half‐Fourier fast spin‐echo (FSE) and 3D true steady‐state free‐precession (SSFP) combined with two time‐spatial labeling inversion pulses (T‐SLIPs), for selective and non‐contrast‐enhanced (non‐CE) visualization of the portal vein.Materials and Methods
Twenty healthy volunteers were examined using half‐Fourier FSE and true SSFP sequences on a 1.5T MRI system with two T‐SLIPs, one placed on the liver and thorax, and the other on the lower abdomen. For quantitative analysis, vessel‐to‐liver contrast (Cv‐l) ratios of the main portal vein (MPV), right portal vein (RPV), and left portal vein (LPV) were measured. The quality of visualization was also evaluated.Results
In both pulse sequences, selective visualization of the portal vein was successfully conducted in all 20 volunteers. Quantitative evaluation showed significantly better Cv‐l at the RPVs and LPVs in half‐Fourier FSE (P < 0.0001). At the MPV, Cv‐l was better in true SSFP, but was not statistically different. Visualization scores were significantly better only at branches of segments four and eight for half‐Fourier FSE (P = 0.001 and 0.03, respectively).Conclusion
Both 3D half‐Fourier FSE and true SSFP scans with T‐SLIPs enabled selective non‐CE visualization of the portal vein. Half‐Fourier FSE was considered appropriate for intrahepatic portal vein visualization, and true SSFP may be preferable when visualization of the MPV is required. J. Magn. Reson.

Purpose
To evaluate the safety and efficacy of iodine-125 (125I) seed strand implantation in combination with transarterial chemoembolization for the treatment of hepatitis B–related unresectable hepatocellular carcinoma (HCC) with portal vein invasion.Materials and Methods
From January 2013 to June 2016, 76 HCC patients with type II tumor thrombus were included in this single-center retrospective study. Twenty patients underwent 125I seed strand implantation combined with transarterial chemoembolization (group A; n = 20), while 56 patients underwent transarterial chemoembolization alone (group B; n = 56). The procedure-related and radiation complications were assessed. Overall survivals were compared by propensity-score analysis.Results
The technique was successfully performed in all patients. The mean intended dose (r = 10 mm; z = 0; 240 days) was 62.6 ± 1.8 Gy. No grade 3 or 4 adverse events related to the procedure occurred in either group. After propensity-score-matching analysis, 19 patients were selected into each group, respectively. In the propensity-matching cohort, the median overall survival time was significantly longer in group A than in the group B (19 pairs; 28.0 ± 2.4 vs 8.7 ± 0.4 mo; P = .001). Treatment strategy, arterioportal shunt, and number of transarterial chemoembolization sessions were significant predictors of favorable overall survival time.Conclusions
125I seed strand implantation combined with transarterial chemoembolization is a safe and effective treatment for HCC patients with portal vein invasion. 相似文献17.

Objective:
To evaluate the overall and cumulative incidence, degree, interval change and predictors of hepatic arterial injury (HAI) after cisplatin and Gelfoam® (Upjohn, Kalamazoo, MI)–based transcatheter arterial chemoembolization (TACE) for hepatocellular carcinoma (HCC).Methods:
A total of 205 patients with HCC who underwent three or more sessions of TACE without additional surgical or local treatment were included. HAI was evaluated at each segment of the hepatic artery using a three-grade scale: 1 (slight wall irregularity), 2 (overt stenosis) and 3 (occlusion). HAI interval change was categorized into three groups: progression, stable state and improvement. Cumulative incidence of HAI was analysed using Kaplan– Meier method, and predictors of HAI (patient age, sex, portal vein thrombosis and Child–Pugh classification) were analysed by univariate logistic regression.Results:
HAI occurred in 50 of the 205 study patients (24.4%). The cumulative incidence of HAI was 16.0% [95% confidence interval (CI), 10.21–21.77] during 5 sessions of TACE, 52.1% (95% CI, 37.83–66.29) during 10 sessions and 68.0% (95% CI, 67.62–88.46) during 15 sessions. Initial HAI was interpreted as grades 1, 2 and 3 in 11 (22.0%), 17 (34.0%) and 22 (44.0%) patients, respectively. When the interval change was assessed in 48 patients with available follow-up TACE, 40 (83.3%) were included in the progression, 2 (4.2%) in the stable state and 6 (12.5%) in the improvement groups. The univariate analysis used to determine the predictors of HAI revealed no significant predictors.Conclusion:
In three or more sessions of TACE, the incidence of HAI was 24%. Increasing TACE causes increased incidence of HAI. The initial presentation was most commonly grade 3, and 12.5% of the patients with HAI showed improvement of the HAI grade during follow-up TACE.Advances in knowledge:
In patients who underwent three or more sessions of cisplatin and Gelfoam–based TACE, the overall incidence of HAI was 24.4%, and increasing TACE causes increased incidence of HAI.Transcatheter arterial chemoembolization (TACE) is an effective method for the palliative treatment of hepatocellular carcinoma (HCC).1 Patients with HCC frequently require repeated TACE for the treatment of residual viable tumour or local recurrence. However, TACE for HCC may cause damage to the hepatic arteries, which leads to hepatic artery spasm and inflammatory constriction, and severe cases may lead to occlusion, dissection, intrahepatic and extrahepatic collateralization and aneurysm formation in the hepatic artery.2–4 A direct result of irreversible occlusion is the difficulty in selecting the artery for the next TACE procedure.5Maeda et al3 reported that the incidence of significant hepatic artery damage after TACE for HCC based on 33 patients and using epirubicin as a chemotherapeutic agent was 16% per artery and 48% per patient (mean follow-up period of 497 days). Geschwind et al6 also reported that subsequent arterial patency seen on follow-up angiography after TACE performed for liver cancer and based on 160 patients was 54.6–80.6% depending on the embolization protocol using oil, polyvinyl alcohol particles or Gelfoam pledgets. However, both of these previous reports had a limited number of study patients. To our knowledge, published reports regarding the incidence or predictors of hepatic arterial injury (HAI) in a large series of cisplatin and Gelfoam-based TACE treatments have been limited, although cisplatin is one of the widely used chemotherapeutic regimens for HCC. Gaba7 reported the results of an online survey replied to by 268 Society of Interventional Radiology members, regarding iodized oil chemoembolization for HCC. The preferred chemotherapeutic regimen consisted of 100 mg of cisplatin (44%), 50 mg of doxorubicin (58%) and 10 mg of mitomycin (59%) emulsified in 10 ml of iodized oil (71%).7 Moreover, follow-up changes in the hepatic artery after HAI have not yet been reported. Therefore, the purpose of this study was to evaluate the incidence, degree, interval change and predictors of HAI after cisplatin and Gelfoam–based TACE for HCC in a 205 patient cohort during a 6-year follow-up. 相似文献18.

Purpose
To examine differences in outcome and response of cirrhotomimetic (CMM) hepatocellular carcinoma (HCC) to a combination of bridging transcatheter arterial chemoembolization and orthotopic liver transplantation (OLT) compared with non-CMM HCC.Materials and Methods
All patients with pathologically proven CMM HCC who underwent bridging transcatheter arterial chemoembolization before OLT between 2007 and 2013 (n = 23) were retrospectively compared with a control group of patients with pathologically proven non-CMM HCC (n = 46).Results
There were 29 tumors in the CMM HCC group and 64 tumors in the non-CMM group identified and treated. Objective response rate on MR imaging at 1 and 3 months after transcatheter arterial chemoembolization for CMM HCC tumors (including patients with complete and partial response) was 93.1% and 86.4% compared with 85.2% and 93.2% for non-CMM tumors without statistically significant difference (P = .54 and P = .09, respectively). Pathologic study of liver explants showed complete tumor necrosis in 62.3% of non-CMM tumors (38/61) compared with 10.3% of CMM tumors (3/29) (P < .0001). Overall 2-year survival after transcatheter arterial chemoembolization and OLT was significantly lower for patients with CMM HCC compared with patients non-CMM HCC (65.2% vs 87%, P = .03). Patients with CMM HCC with extranodular tumor extension involving > 50% of liver parenchyma had worse survival with mean 2-year survival of 402 days ± 102 vs 656 days ± 39 for the remaining patients with CMM HCC (P = .02).Conclusions
Despite similar early imaging response rates, CMM HCC tumors had markedly lower rates of complete pathologic necrosis on liver explants and were associated with reduced survival after OLT compared with conventional HCCs. 相似文献19.

Purpose
To evaluate feasibility of using three-dimensional (3D) quantitative color-coding analysis (QCA) to quantify substasis endpoints after transcatheter arterial chemoembolization of hepatocellular carcinoma (HCC).Materials and Methods
This single-institution prospective study included 20 patients with HCC who had undergone segmental or subsegmental transcatheter arterial chemoembolization between December 2015 and March 2017. The chemoembolization endpoint was a sluggish anterograde tumor-feeding arterial flow without residual tumor stains. Contrast medium bolus arrival time (BAT) was used as an indicator of arterial flow. BAT of the proper hepatic artery was obtained as a reference point. BATs of the proximal right lobar artery, proximal left lobar artery, and segmental artery that received embolization were analyzed before and after chemoembolization. Wilcoxon signed rank test was used to evaluate the difference between BATs before and after chemoembolization.Results
BATs before and after chemoembolization of the segmental artery that received embolization were 0.47 seconds (interquartile range [IQR], 0.31–0.70 s) and 1.04 seconds (IQR, 0.78–2.01 s; P < .001), respectively. BATs before and after chemoembolization of the proximal left lobar hepatic artery (0.35 s [IQR, 0.11–0.55] and 0.13 s [IQR, 0.05–0.32], P = .025) and right lobar hepatic artery (0.23 s [IQR, 0.13–0.65] and 0.22 s [IQR, 0.08–0.39], P = .027) exhibited no significant change.Conclusions
3D QCA is a feasible method for quantifying sluggish segmental arterial flow after transcatheter arterial chemoembolization in patients with HCC. 相似文献20.
