BACKGROUND The treatment outcome of transarterial chemoembolization (TACE) in unresectable hepatocellular carcinoma (HCC) varies greatly due to the clinical heterogeneity of the patients. Therefore, several prognostic systems have been proposed for risk stratification and candidate identification for first TACE and repeated TACE (re-TACE). AIM To investigate the correlations between prognostic systems and radiological response, compare the predictive abilities, and integrate them in sequence for outcome prediction. METHODS This nationwide multicenter retrospective cohort consisted of 1107 unresectable HCC patients in 15 Chinese tertiary hospitals from January 2010 to May 2016. The Hepatoma Arterial-embolization Prognostic (HAP) score system and its modified versions (mHAP, mHAP2 and mHAP3), as well as the six-and-twelve criteria were compared in terms of their correlations with radiological response and overall survival (OS) prediction for first TACE. The same analyses were conducted in 912 patients receiving re-TACE to evaluate the ART (assessment for re-treatment with TACE) and ABCR (alpha-fetoprotein, Barcelona Clinic Liver Cancer, Child-Pugh and Response) systems for post re-TACE survival (PRTS). RESULTS All the prognostic systems were correlated with radiological response achieved by first TACE, and the six-and-twelve criteria exhibited the highest correlation (Spearman R = 0.39, P = 0.026) and consistency (Kappa = 0.14, P = 0.019), with optimal performance by area under the receiver operating characteristic curve of 0.71 [95% confidence interval (CI): 0.68-0.74]. With regard to the prediction of OS, the mHAP3 system identified patients with a favorable outcome with the highest concordance (C)-index of 0.60 (95%CI: 0.57-0.62) and the best area under the receiver operating characteristic curve at any time point during follow-up; whereas, PRTS was well-predicted by the ABCR system with a C-index of 0.61 (95%CI: 0.59-0.63), rather than ART. Finally, combining the mHAP3 and ABCR systems identified candidates suitable for TACE with an improved median PRTS of 36.6 mo, compared with non-candidates with a median PRTS of 20.0 mo (log-rank test P < 0.001). CONCLUSION Radiological response to TACE is closely associated with tumor burden, but superior prognostic prediction could be achieved with the combination of mHAP3 and ABCR in patients with unresectable liver-confined HCC.

We aimed to detect alterations in diffusion characteristics of brain white matter in hepatic myelopathy (HM) patients. Liver cirrhosis patients with (n=25) and without (n=18) HM after transjugular intrahepatic portosystemic shunt and 26 healthy controls were enrolled in this study. All participants were scanned with diffusion tensor imaging on a 3T Siemens scanner. Tract-based spatial statistics analysis was used to detect abnormalities of intracranial white matter tracts. Correlations between clinical characteristics and diffusion metrics were also calculated. HM patients showed widespread decreased fractional anisotropy values in association fibers, callosal fibers, thalamic fibers, and limbic system fibers (P

Objective This prospective non-randomized controlled trial aimed to compare the efficacy of sorafenib in combination with transarterial chemoembolization (TACE) vs TACE alone for the treatment of patients with unresectable intermediate or advanced hepatocellular carcinoma. Methods A total of 304 patients were enrolled, in which 82 received concurrent sorafenib (400 mg orally twice daily, initiated within 14 days after TACE), and these patients were matched with 164 patients who received TACE alone at a 1:2 ratio using propensity score matching to minimize selection bias. The response to treatment, time-to-progression (TTP), overall survival (OS) as well as adverse events were compared between the two groups. Results During a median follow-up period of 21.4 weeks (range 0.5–103 weeks), the addition of sorafenib prolonged TTP (6.3 vs 4.3 months; hazard ratio [HR] 0.60, 95% CI 0.422–0.853, P = 0.004) and median survival (7.5 vs 5.1 months; HR 0.61, 95% CI 0.423–0.884, P = 0.009) compared with TACE alone. Significant prognostic factors for OS by multivariate analysis included the use of sorafenib, Barcelona Clinic Liver Cancer stage, metastasis/vascular invasion and Child-Pugh score. Conclusions The combined use of sorafenib and TACE was generally well tolerated and significantly improved OS and TTP compared with TACE alone in patients with intermediate or advanced HCC. Further studies are warranted to confirm the safety and efficacy of this combination therapy.

AimTo evaluate the effect of the shunting branch of the portal vein (PV) (left or right) and the initial stent position (optimal or suboptimal) of a transjugular intrahepatic portosystemic shunt (TIPS).MethodsWe retrospectively reviewed 307 consecutive cirrhotic patients who underwent TIPS placement for variceal bleeding from March 2001 to July 2010 at our center. The left PV was used in 221 patients and the right PV in the remaining 86 patients. And, 224 and 83 patients have optimal stent position and sub-optimal stent positions, respectively. The patients were followed until October 2011 or their death. Hepatic encephalopathy, shunt dysfunction, and survival were evaluated as outcomes. The difference between the groups was compared by Kaplan-Meier analysis. A Cox regression model was employed to evaluate the predictors.ResultsAmong the patients who underwent TIPS to the left PV, the risk of hepatic encephalopathy (P = 0.002) and mortality were lower (P < 0.001) compared to those to the right PV. Patients who underwent TIPS with optimal initial stent position had a higher primary patency (P < 0.001) and better survival (P = 0.006) than those with suboptimal initial stent position. The shunting branch of the portal vein and the initial stent position were independent predictors of hepatic encephalopathy and shunt dysfunction after TIPS, respectively. And, both were independent predictors of survival.ConclusionTIPS placed to the left portal vein with optimal stent position may reduce the risk of hepatic encephalopathy and improve the primary patency rates, thereby prolonging survival.

To identify the risk factors of early post-TIPS hepatic encephalopathy (HE) and the long-time survival of patients with or without early post-TIPS HE.Consecutive cirrhotic patients who underwent TIPS for variceal rebleeding or refractory ascites in our center from January 2003 to December 2008 were included in this study. More than 60 clinical characteristics were enrolled in univariate analysis and logistic regression analysis to define the risk factors of HE in 3 months after TIPS procedure (early post-TIPS HE). The long-time survival of patients with or without early post-TIPS HE was compared by Cox regression with several covariates.According to our inclusion criteria, 190 patients were included. The median follow-up was 30.5 months. Lower serum concentration of fibrinogen and higher Child-Pugh score were the independent risk factors for suffering early post-TIPS HE. Patients without early post-TIPS HE after TIPS showed better prognosis than those with early post-TIPS HE after TIPS (P = 0.044).Patients with lower serum fibrinogen and higher Child-Pugh score before TIPS might be more probably attacked by early post-TIPS HE which indicated worse long-term survival.

To evaluate retrospectively the feasibility, efficacy and safety of transjugular intrahepatic portosystemic shunt (TIPS) or percutaneous transhepatic or transsplenic approach to the portal vein with the combination of TIPS for the treatment of patients with portal vein thrombosis with or without cavernous transformation.Sixty-five patients with portal vein thrombosis from July 2002 to August 2007 at our hospital were analyzed retrospectively. Indirect portography through superior mesenteric artery was performed to determine the approaches for TIPS procedure. If the intrahepatic portal vein branches were visualized, TIPS was implemented directly from transjugular approach; if the intrahepatic portal vein branches failed to be visualized, an ultrasound-guided percutaneous transhepatic or transsplenic approach was performed to recanalize the thrombosed portal vein initially followed by TIPS placement to reconstruct the portal venous flow. Efficacy and complications were observed and revision and survival rates monitored during the follow-up.TIPS were successfully created in 54 of 65 patients with portal vein thrombosis with a success rate of 83.1%. Among them, TIPS were performed directly in 36 of 40 patients; portal vein recanalization were successfully performed via transhepatic access in 15 of 25 patients, and 3 of remaining 5 who failed the transhepatic approach were successfully done from transsplenic access. Then TIPS placement was accomplished with a success rate of 72.0% (18/25). The success rate in cirrhotic patients was 82.4% (42/51) and it was not significant different from those without cirrhosis 85.7% (12/14) (P = 0.766). While the success rate in the patients with cavernous transformation 71.8% (28/39) showed a significant difference compared to that without cavernous transformation 100% (26/26) (P = 0.002). The success rates in portal vein thrombosis and cavernous transformation with or without cirrhosis were 42.9% (18/42) and 83.3% (10/12) respectively, exhibiting a significant difference (P = 0.021). The mortality rate of 30 days post-operation was 3.7% (2/54). From Day 1 to 63 months follow-up, The incidence rate of hepatic encephalopathy was 27.8% (15/54); revision rate 22.2% (12/54); median survival time 31.4 months.Conventional TIPS or percutaneous transhepatic or transsplenic approach combined with TIPS for the treatment of portal vein thrombosis with or without cavernous transformation are feasible, safe and effective. It is essential to recanalize the thrombosed portal vein initially followed by TIPS placement to reconstruct the portal venous flow.

OBJECTIVES: Evaluate the effect of an implanted percutaneous left subclavian artery port-catheter drug delivery system for regional chemotherapy of inoperable pancreatic carcinoma. METHODS: One hundred and forty patients with inoperable pancreatic carcinoma were enrolled and randomized into two groups to receive the FAM regimen on a 6-day cycle at 1-month intervals: 70 patients in the regional interventional chemotherapy group in which treatment was infused directly into the common hepatic artery, and 70 patients who received the same chemotherapy regimen via the peripheral vein. RESULT: In the interventional chemotherapy group, there were 5 cases of complete remission (CR) and 49 cases of partial remission (PR), giving a response rate (CR+PR) of 77.1%; pain control was effective in 95.7% cases; survival time was 3–34 months (median 13.5). There was no case of CR in the systemic chemotherapy group, and 25 cases of PR, giving a response rate of 35.7%; pain control was effective in 35.7%, and survival time was 1–13 months (median 6.2). The differences between the two groups in response rate and survival were statistically significant (P
