RÉSUMÉ

Objective:To evaluate whether underdilated stent could reduce the occurrence of hepatic encephalopathy (HE) after transjugular intrahepatic portosystemic shunt (TIPS) creation.Methods:A total of 197 patients with decompensated liver cirrhosis, who had underwent TIPS creation at Union Hospital, Tongji Medical College, Huazhong University of Science and Technology, were analyzed retrospectively, including 110 males and 87 females with age 25-79 (54±11) years old. Uncovered and covered stents with 8 mm diameter were implanted in all subjects, and then dilated by balloon catheters with 6 mm or 8 mm diameter. The patients were divided into two groups, including underdilated group (6 mm, n=105) and control group (8 mm, n=92).Kaplan-Meier curves were used to illustrate cumulative rate of HE, and the differences were assessed with the log-rank test. Multivariate analyses with a Cox regression model were conducted to explore the risk factors for HE. Results:During a median follow-up period of 29 (12-54) months, 16 (15.2%) patients developed HE in the underdilated group and 27 (29.3%) patients in the control group. There was a significant difference in the cumulative rate of HE ( P=0.014), but no statistical differences were found in terms of variceal rebleeding, shunt dysfunction and survival between the two groups ( P=0.608, P=0.659, P=0.968). In multivariated analysis, group assignment (underdilated vs. control, HR=0.291, 95% CI 0.125-0.674, P=0.004) was identified as an independent risk factor for HE after TIPS creation. Conclusion:Underdilated TIPS could reduced the risk of HE compared with completely dilated TIPS, with comparable risk of variceal rebleeding, shunt dysfunction and mortality. And it is worthy of applying this technique to a large sample of patients in clinical practice.

RÉSUMÉ

Objective To investigate the cost-effect of transarterial chemoembolization (TACE) with CalliSpheres beads loaded with arsenic trioxide (ATO) (CBATO) versus ATO iodized oil emulsion (conventional TACE, cTACE) in the treatment of unresectable liver cancer. Methods A total of 100 patients with advanced liver cancer who attended The First Affiliated Hospital of Zhengzhou University from May 2017 to December 2018 were enrolled and divided into CBATO group( n =45) and cTACE group( n =55) according to the treatment regimen. Progression-free survival (PFS) was used to evaluate the efficacy of quality-adjusted life year (QALY), and European Quality of Life-5 Dimensions (EQ-5D) index was used to evaluate quality of life. The t -test was used for comparison of continuous data between groups, and the chi-square test was used for comparison of categorical data between groups; the number of surgeries, length of hospital stay, treatment cost, and incremental cost-effectiveness ratio (ICER) were calculated for the two groups, and then a cost-effect analysis was performed. Results Within the PFS time, the per capita hospital cost was 96 446 yuan in the CBATO group and 91 230.43 yuan in the cTACE group. There were significant differences between the two groups in the mean number of surgeries (2.5±0.7 vs 3.4±0.8, t =16.911, P < 0.01) and mean hospital stay (5.8±1.2 days vs 7.5±1.8 days, t =12.459, P < 0.01). The CBATO group had a significantly higher QALY than the cTACE group (0.804 vs 0.512). Compared with the cTACE group, the CBATO group had an ICER of 17 861.53 yuan/QALY for unresectable liver cancer. Conclusion Although CBATO has a higher surgery cost than cTACE, CBATO has a better clinical effect than cTACE and can reduce the number of surgeries and length of hospital stay, with a better postoperative quality of life than cTACE, suggesting that CBATO has marked cost-effect advantages.

RÉSUMÉ

Objective:To investigate the morphological feature and clinical significance of MRI around tumor after drug-eluting bead transcatheter arterial chemoembolization (DEB-TACE) of primary hepatocellular carcinoma.Methods:We reviewed and analyzed the data of hepatocellular carcinoma patients admitted from January 2017 to December 2018 in the Department of Radiological Intervention of the First Affiliated Hospital of Zhengzhou University. A total of 42 patients were enrolled, including 35 males and 7 females, aged (57.0±11.9) years. For the first time after operation, MRI enhancement showed peri-tumor margin enhancement as the starting point of follow-up. Follow-up and measure enhanced edge thickness, delayed enhancement, progression or remission data.Results:A total of 49 tumors and 84 peritumoral enhancement margins were included in 42 patients, with 30 sharp type , 40 rough type and 14 nodular type. The thickness of sharp type is less than that of rough type and nsodular type, and the differences were statistically significant (all P<0.05). The sharp type is the majority of the tumors with maximum diameter <5 cm, rough type and nodule type are the majority of tumors with maximum diameter ≥5 cm. Most of the sharp type are continuously enhanced, while the rough type and nodular type are not. Most sharp type relief (93.3%, 28/30), while rough type (80.0%, 32/40) and nodular type ( n=12) are mostly of deterioration, the differences are statistically significant (all P<0.05). Conclusion:Compared with the rough type and nodular type, the sharp type usually occurs in smaller tumors and more prone to local mitigation in the enhanced morphology around MRI after DEB-TACE in primary hepatocellular carcinoma.

RÉSUMÉ

ObjectiveTo investigate the effect of arsenic trioxide-loaded CalliSpheres beads (CBATO) in transarterial chemoembolization (TACE) in the treatment of rabbits with VX2 liver tumor. MethodsA total of 120 tumor-bearing rabbits were divided into control group, CalliSpheres beads (CB) group (blank beads for TACE), CBATO group, and conventional TACE (cTACE) group (arsenic trioxide lipiodol for TACE) using a random number table, with 30 rabbits in each group. Five rabbits in each group were sacrificed at 12 hours and on days 3, 7, and 14 after TACE, and immunohistochemistry was used to measure the proliferation index and apoptosis percentage of tumor cells in the residual tumor area. The tumor necrotic volume was measure on day 7 after TACE, and the growth rate and necrosis rate of tumor cells were calculated. Ten rabbits were randomly selected from each group for the observation of survival time. An analysis of variance was used for comparison of continuous data between multiple groups, and the least significant difference t-test was used for further comparison between two groups; the Kaplan-Meier survival analysis was used to evaluate survival time, and the log-rank test was used for comparison. ResultsOn day 7 after TACE, the CBATO group had a significantly lower growth rate and a significantly higher necrosis rate of tumor cells than the cTACE group, the CB group, and the control group (all P<0.05). At each time point after TACE, there were significant differences in the proliferation index and apoptosis percentage of tumor cells between the CBATO group and the other three groups (all P<0.05). The median survival time was 26 days in the CBATO group, 18.5 days in the CB group, 22 days in the cTACE group, and 15.5 days in the control group, and the CBATO group had a significantly longer survival time than the other three groups (χ2=3.95, 8.99, and 13.47, P=0.049, P=0.003, and P<0.01). ConclusionCBATO has a better effect than cTACE and CB in the treatment of rabbits with VX2 liver tumor and can significantly improve tumor necrosis rate, promote the apoptosis of tumor cells, and prolong the survival time of experimental animals.

RÉSUMÉ

Objective: To explore the effect of transcatheter embolization combined with radiofrequency ablation (RFA) in treatment of VX2 liver tumors of rabbits. Methods: Sixty rabbit VX2 liver tumor models were randomly divided into 4 groups (each n=15). Fifteen minutes after TACE or transcatheter arterial embolization (TAE), RFA was performed in both TACE+RFA group and TAE+RFA group, respectively.And RFA group was only treated with RFA, TACE group underwent only TACE. Serum aspartate aminotransferase (AST) and alanine aminotransferase (ALT) were measured 1 day before and 3 and 7 days after operation. Tumor growth rate, tumor necrosis rate and Suzuki score were measured 7 days after operation. The expression of heat shock protein 70 (HSP70) in liver lesions surrounding ablation zone or embolized zone was detected with immunohistochemistry 1, 3 and 7 days after operation, and hepatocyte apoptosis index and proliferation index were calculated. Results: The levels of ALT and AST in TACE+RFA group were higher than those in other groups 3 and 7 days after operation (all P<0.05). Seven days after operation, the Suzuki score in TACE+RFA group was higher than that in other groups, and tumor growth rates in TACE+RFA and TAE+RFA groups significantly decreased, while the necrosis rates in TACE+RFA and TAE+RFA groups increased compared with RFA and TACE groups (all P<0.05). The expression of HSP70 in hepatic lesions surrounding the ablation zone or embolized zone increased gradually 1, 3 and 7 days after operation, and in TACE+RFA group were higher than in other groups, in TAE+RFA group were higher than in TACE group and RFA group 3 days after operation (all P<0.05). The hepatocyte apoptosis index in hepatic lesions surrounding the ablation zone or embolized zone decreased gradually in all 4 groups 1, 3 and 7 days after operation, while in TACE+RFA group were higher than the other 3 groups, in TACE group 1 and 3 days after operation were higher than in TAE+RFA group and RFA group (all P<0.05). The hepatocyte proliferation index in 4 groups were higher 3 days after operation than that 1 and 7 days after operation, and compared with other groups, in TAE+RFA group were higher 1, 3 and 7 days after operation, in RFA group was higher 1 and 3 days after operation than in TACE+RFA group and TACE group (all P<0.05). Conclusion: The effects of TACE+RFA and TAE+RFA on inhibiting tumor growth are better than TACE and RFA alone for treatment of VX2 liver tumors of rabbits. Compared with TACE+RFA, TAE+RFA can promote hepatocyte proliferation and inhibit hepatocyte apoptosis more effectively with less liver damage.
