Hepatocellular carcinoma (HCC) is one of the most common types of malignant tumor. Although radical surgery and liver transplantation are possible cures for the disease, most patients are beyond the optimum stage for radical treatment at the time of diagnosis. Transarterial chemoembolization (TACE) is the first choice of treatment for advanced HCC. Owing to the widespread use of conventional TACE (cTACE), the problems with this treatment cannot be ignored. Drug-eluting beads (DEBs), a new type of embolization material, appear to overcome the problems of cTACE, and they have other advantages such as synchronous controlled continuous drug release after chemotherapy and embolization and low blood concentrations after treatment. This review summarizes the recent advances in the use of DEB-TACE to treat HCC. 相似文献

Transarterial chemoembolization (TACE) is a minimally invasive procedure involving intra-arterial catheter-based chemotherapy to selectively administer high doses of cytotoxic drugs to the tumor bed along with ischemic necrosis induced by arterial embolization. Chemoembolization forms the essential core of management in patients with hepatocellular carcinoma (HCC) who are not suitable for curative therapies such as transplantation, resection, or percutaneous ablation. TACE of hepatic cancer(s) has proven to be helpful in achieving local tumor control, and has supported the ability to prevent tumor progression, prolong patient life, and manage patient symptoms. Recent data have demonstrated that, in patients with single-nodule HCC ≤3 cm without vascular invasion, the 5-year overall survival with TACE was found to be comparable with hepatic resection and radiofrequency ablation. Used for several years, Lipiodol continues to play a vital role as a tumor-seeking and radiopaque drug delivery vector in interventional oncology. Efforts have been made to enhance the administration of chemotherapeutic agents to tumors. Compared with conventional TACE, drug-eluting bead TACE is a fairly new drug delivery embolization technique that permits fixed dosing and has the ability to provide sustained release of anticancer agents over a period of time. The present review discusses the basic procedure of TACE and its properties, and the effectiveness of conventional and drug-eluting bead chemoembolization systems currently available or presently undergoing clinical evaluation. 相似文献

Background The purpose of this study was to assess the accuracy of double-contrast magnetic resonance (MR) imaging for the treatment
response evaluation of hepatocellular carcinoma (HCC) in cirrhotic liver after transarterial chemoembolization (TACE).
Methods Twenty-two patients with 30 HCC nodules treated by TACE underwent double-contrast MR imaging 1 month after treatment. MR images
were obtained before and after the sequential administration of superparamagnetic iron oxide (SPIO) and gadopentetate dimeglumine
contrast agent within the same imaging session. Two observers retrospectively assessed all treated nodules for evidence of
residual viable tumor after TACE. The diagnostic performance of gadolinium-enhanced, SPIO-enhanced, and double-contrast enhanced
images was calculated. Histopathological and angiographical findings served as standard of reference. Receiver operating characteristic
curves and areas under the curves (A
z) were calculated.
Results Double-contrast technique (A
z = 0.95) was significantly (p = 0.036) more accurate than SPIO-enhanced technique (A
z = 0.92) and gadolinium-enhanced technique (p = 0.005) (A
z = 0.81) in viable tumor detection after TACE. Double-contrast technique was significantly more sensitive (92%) than SPIO-enhanced
technique (80%) and gadolinium-enhanced technique (68%). Kappa values for interobserver agreement ranged from 0.67 to 0.87
and were significantly different from zero (all p < 0.001).
Conclusions Compared to gadolinium-enhanced and SPIO-enhanced techniques, double-contrast technique significantly improves the detection
of viable tumor in HCC after TACE. 相似文献

Objective: This study aims to explore the clinical effectiveness of a combination therapy of transarterial chemoembolization (TACE) and percutaneous microwave coagulation therapy (PMCT) in treating hepatocellular carcinoma (HCC) abutting the diaphragm. Material and methods: Six cases with HCC were treated with TACE followed by PMCT one month later with the aid of artificial pneumothorax. Results: CT/MRI revealed complete necrosis in the tumor lesions and the treated tumor margins (≥5?mm). Serum alpha-fetoprotein (AFP) levels markedly declined in patients who originally had higher serum AFP levels. Postoperative complications such as fever, mild hepatic dysfunction and pleural effusion were alleviated within a short period of time. All patients were closely monitored through follow-up; all patients survived, except for one patient who received a liver transplantation. Conclusions: As lesions are either invisible or poorly visible in sonography, determining an effective treatment for HCC abutting the diaphragm remains a particular challenge. TACE and PMCT combined therapy with the aid of artificial pneumothorax proved to be an available treatment option. 相似文献

Transarterial chemoembolization (TACE) has the potential to improve survival in patients with intermediate stage hepatocellular
carcinoma (HCC). Careful selection of patients is mandatory to gain survival benefit and safe quality of life. Basic principles
of TACE in HCC include selective treatment via intrahepatic and extrahepatic arteries, proper management of side effects and
continuation of treatment guided by imaging. After conventional TACE, based on delivery of cytotoxic drugs emulsified in iodized
oil and embolization of various types of particles, has been used for more than 20 years, the new concept of drug-eluting
microspheres has been introduced. This technology effectively combines enhanced local drug delivery and ischemic embolization
effects. Clinical studies showed intensified local necroses and reduced systemic toxic side effects compared to conventional
TACE. Embolization of HCC with sub-100 μm particles penetrating deeply into the tumor vascular bed is another promising new
option. Very effective devascularization of HCC nodules has been shown after 40 μm bland embolizations, however, potential
risks like passage of particles into hepatic veins and systemic circulation have to be considered. Today the indication for
TACE in intermediate stage HCC patients is widely accepted; however, there is no clear methodical standard so far. Further
studies are necessary to define how to adapt various available methods to individual HCC and patients characteristics. 相似文献

ObjectiveTo analyze the radiation dose received by patients during hepatic artery infusion chemotherapy (HAIC) and transarterial chemoembolization (TACE) procedures and the related influencing factors.MethodsData of 162 cases in the HAIC group and 230 cases in the TACE group were collected. The included covariates were Age (<45/45–59/≥60 years), BMI levels (underweight/normal weight/obesity), focus Dye of tumor (present/absent), lesion size (<5cm/≥5cm), superselection (present/absent), hepatic vascular variation (present/absent). The endpoints were postoperative dose-area product (DAP), exposure time and Air kerma (AK).ResultsOf all included patients, the HAIC group patients were younger than those in the TACE group (P = 0.028). The proportion of patients with large lesions in the HAIC group was higher than the TACE group (45.7% vs. 33.9%, P = 0.019). The proportion of patients who had superselection was lower in the HAIC group as compared to the TACE group (61.7% vs. 82.2%, P < 0.001). Generally, the HAIC group has lower DAP, exposure time and AK by 36.3% (P < 0.001), 38.2% (P < 0.001), and 41.3% (P < 0.001) than the TACE group, respectively. Linear regression analysis showed the procedure method (HAIC/TACE, P < 0.001), type of DSA machine (Pheno/FD20, P < 0.001), BMI levels (P < 0.001), age (P = 0.021), lesion size (<5cm/≥5 cm, P = 0.031) significantly correlated with low DAP. In the HAIC group, the type of DSA machine and BMI correlated with the radiation dose, while in the TACE group, the type of DSA machine, BMI, and lesion size correlated with the radiation dose.ConclusionCompared with TACE, HAIC enables doctors and patients to receive lower radiation doses. Obese patients in both HAIC and TACE groups increase the radiation exposure in interventional doctors and patients, but large lesions only affect the radiation dose in the TACE procedure. 相似文献

PurposeThe study aimed to establish a prognostic prediction model and an artificial neural network (ANN) model to determine who will benefit from transarterial chemoembolization (TACE) monotherapy for patients with hepatocellular carcinoma (HCC) invading portal vein.MethodsTreatment-naïve patients with HCC and portal vein invasion who were treated with TACE monotherapy at hospital A as training cohort and hospital B as validation cohort were included. The primary endpoint was overall survival (OS). In training cohort, independent risk factors associated with OS were identified by univariate and multivariate analysis. The prognostic prediction (PP) and ANN models based on the independent risk factors were established to find out who will benefit most from TACE monotherapy. The type of portal vein tumor thrombosis was classified based on the Cheng’s Classification. The accuracy of the models was validated in validation cohort.ResultsTotally, 242 patients (training cohort: n = 159; validation cohort: n = 83) were included. The median OS was 7.1 and 8.5 months in training and validation cohort, respectively. In training cohort, the PP model was established based on the following five independent risk factors: Cheng’s Classification, Eastern Cooperative Oncology Group score, maximum tumor size, number of HCC nodules, and Child-Pugh stage. PP score of 17.5 was identified as cut-off point and patients were divided into two groups by PP score <17.5 and >17.5 in survival benefit and prognostication (8.8 vs. 5.5 months; P < 0.001). These five factors were included and ranked based on the importance associated with OS in the ANN model. Both of the two models received high accuracy after validation.ConclusionsPortal vein invaded HCC patients with PP score <17.5 may benefit most from TACE monotherapy. For these patients, TACE monotherapy should be considered. 相似文献

Background: To assess unenhanced and gadolinium-enhanced magnetic resonance (MR) imaging patterns of hepatocellular carcinoma (HCC) treated
with transarterial chemoembolization (TACE).
Methods: Thirty-two patients with 48 HCC lesions underwent MR imaging before and 15 days after TACE. Fifteen lesions were then surgically
resected. The remaining 33 lesions were not removed and were followed up with MR imaging at 3, 6, 12, and 18 months after
treatment. Spin echo (SE) T1- and T2-weighted and gadolinium-enhanced SE T1-weighted sequences were employed. Qualitative
evaluation of signal intensity pattern of the treated lesions was performed in all cases. Histological evaluation and selective
hepatic arteriography were considered the gold standard of the study for the 15 resected lesions and the 33 unresected lesions,
respectively.
Results: On follow-up enhanced T1-weighted images of the 15 resected lesions, seven showed no area of enhancement corresponding to
complete necrosis at histologic examination. The remaining eight resected lesions showed areas of enhancement; in six of these
cases, viable tumor tissue was found at histology; in the other two lesions, histologic examination revealed the presence
of complete tumor necrosis. In the group of resected lesions, T2-weighted images showed no pattern characteristic of necrosis.
In 24 of 33 unresected lesions, loss of enhancement on follow-up enhanced T1-weighted images was a characteristic finding,
which correlated to devascularization at arteriography. Of these 24 lesions, 17 were completely hypointense on follow-up T2-weighted
images; the remaining seven showed small foci of hyperintensity. The other nine unresected lesions showed enhanced portions
on follow-up enhanced T1-weighted images, which corresponded to hyperintense areas on T2-weighted images. These findings correlated
to persistence of hypervascular areas at arteriography.
Conclusion: Gadolinium-enhanced T1-weighted MR imaging is a reliable method for evaluating the outcome of TACE treatment and is more
accurate than unenhanced T2-weighted MR imaging.
