The purpose of this study was to assess the clinical effects of transcatheter arterial chemoembolization (TACE) during the corresponding portal vein occlusion (TACE-PVO) in patients with hepatocellular carcinoma (HCC) and marked arterioportal (AP) shunts. This was a prospective, nonrandomized study of TACE-PVO in patients with HCC who had marked AP shunts. The subjects were 21 patients with unresectable HCC and marked AP shunts who underwent shunt embolization with the use of coils and/or gelatin-sponge particles (group A: n = 7) or by TACE-PVO (group B: n = 14). Clinical parameters and data on embolization of AP shunts and on tumor response were assessed prospectively. No major procedure-related complication occurred in either group. Effectiveness of AP-shunt treatment was significantly better in group B than in group A in terms of both immediate results (P = 0.009) and subsequent results (P = 0.028). Tumor response in the therapeutic target area was significantly (P = 0.002) better in group B than in group A. Survival was significantly better in group B than in group A (P = 0.008). TACE-PVO may be a safe and useful therapy for selected patients with unresectable HCC and marked AP shunts.
"We attempted to overcome this complication by performing TACE of tumor-feeding arteries with occlusion of the corresponding portal vein. This method of TACE during portal vein occlusion (TACE-PVO)  was designed to permit treatment of HCC with significant arteriohepatic vein shunts as mentioned above . We modified the technique by concurrently performing percutaneous transhepatic portography after evaluation of hemodynamic changes in the liver with portal vein occlusion . "
[Show abstract][Hide abstract] ABSTRACT: Hepatocellular carcinoma (HCC) is the sixth most common cancer and the third leading cause of cancer-related deaths in the world. The Barcelona Clinic Liver Cancer (BCLC) classification has recently emerged as the standard classification system for clinical management of patients with HCC. According to the BCLC staging system, curative therapies (resection, transplantation, and percutaneous ablation) can improve survival in HCC patients diagnosed at an early stage and offer potential long-term curative effects. Patients with intermediate-stage HCC benefit from transcatheter arterial chemoembolization (TACE), and those diagnosed at an advanced stage receive sorafenib, a multikinase inhibitor, or conservative therapy. Most patients receive palliative or conservative therapy only, and approximately 50% of patients with HCC are candidates for systemic therapy. TACE is often recommended for advanced-stage HCC patients all over the world because these patients desire therapy that is more effective than systemic chemotherapy or conservative treatment. This paper aims to summarize both the published data and important ongoing studies for TACE and to discuss technical improvements in TACE for advanced-stage HCC.

[Show abstract][Hide abstract] ABSTRACT: Fe-doped or undoped semi-insulating InP samples submitted to high temperature annealing process have been studied by Photoinduced current transient spectroscopy (PICTS) in order to compare the traps observed. The PICTS spectra of these samples show separately the presence of a multitude of traps having activation energies ranging from 0.12 eV to 0.66 eV. The Fe<sub>In</sub> trap level has not been clearly observed in all the samples. The comparison of the thermal parameters of the observed traps allows to assign some of them to a same defect. However the identification seems to be less evident concerning other traps and should be rather related to the properties of the starting material

[Show abstract][Hide abstract] ABSTRACT: OBJECTIVE: Portal vein embolization (PVE) has been widely used to facilitate major liver resection; however, curative surgery even after PVE may not be possible mainly because of inadequate hypertrophy of remnant liver or disease progression. For these patients, transcatheter arterial chemoembolization (TACE) is the next therapeutic option. We evaluated the safety and efficacy of TACE after PVE in 25 patients with hepatocellular carcinoma (HCC). CONCLUSION: TACE using a single chemotherapeutic agent can be performed safely and effectively in HCC patients who previously underwent PVE. TACE after PVE allowed two of the patients to be downstaged so they could undergo surgical resection.
