Hypoxia-induced HMGB1 expression of HCC promotes tumor invasiveness and metastasis via regulating macrophage-derived IL-6.

Hypoxia is associated with the progression of hepatocellular carcinoma through promotion of spontaneous metastasis but the mechanism remains unclear. Here, we hypothesis that tumor cell-derived HMGB1 orchestrates macrophages infiltration and promotes metastasis of HCC via enhancing macrophage-secreted IL-6 under hypoxia. HMGB1 expression was robustly exacerbated in tumors of HCC patients with PVTT.

Posttreatment contrast-enhanced computed tomography and/or magnetic resonance imaging were retrieved and reviewed for tumor response to the treatment.

Transcatheter arterial chemoembolization with gemcitabine and oxaliplatin for the treatment of advanced biliary tract cancer.

Background: The aim of this study was to determine the therapeutic efficacy and safety of transarterial chemoembolization (TACE) with gemcitabine and oxaliplatin in patients with advanced biliary tract cancer (BTC).

Methods: We retrospectively analyzed the outcomes for 65 patients with advanced BTC treated by TACE with gemcitabine 1,000 mg/m(2) and oxaliplatin 100 mg/m(2). Follow-up laboratory tests and computed tomography or magnetic resonance imaging were performed routinely to evaluate the response of the tumor to treatment.

Portal hypertension induced by congenital hepatic arterioportal fistula: report of four clinical cases and review of the literature.

Intrahepatic arterioportal fistula (IAPF) can be caused by many secondary factors. We report four cases of portal hypertension that were eventually determined to be caused by congenital hepatic arterioportal fistula. The clinical manifestations included ascites, variceal hemorrhage and hepatic encephalopathy.

Arsenic trioxide: marked suppression of tumor metastasis potential by inhibiting the transcription factor Twist in vivo and in vitro.

Purpose: Arsenic trioxide (ATO) has been found effective in several types of cancer cells, including acute promyelocytic leukemia, and recently in hepatocellular carcinoma (HCC). In this study, we investigated the role of ATO in regulating the invasive activity of HCC after transarterial embolization (TAE).

Methods: Cell migration and invasion were observed using Transwell and wound-healing assay.

Transcatheter arterial embolization promotes liver tumor metastasis by increasing the population of circulating tumor cells.

Transcatheter arterial embolization (TAE) is widely used as an effective palliative treatment for hepatocellular carcinoma (HCC), and can prolong survival time. However, the high incidence of tumor recurrence and metastasis after TAE is still a major problem. Recent studies demonstrated that circulating tumor cells (CTCs) contribute to tumor metastasis.

Increased metastatic potential of residual carcinoma after transarterial embolization in rat with McA-RH7777 hepatoma.

Transarterial chemoembolization represents a first-line non-curative therapy for hepatocellular carcinoma (HCC), although the biological changes in the remaining cancer after embolization are not completely understood. In the present study, we examined whether transarterial embolization (TAE) enhances the metastatic potential of residual HCC and investigated the mechanisms underlying embolization. The hepatoma cell line McA-RH7777, which is marked by green fluorescent protein (GFP), was used in the study.

Three-dimensional whole-liver perfusion magnetic resonance imaging in patients with hepatocellular carcinomas and colorectal hepatic metastases.

Background: Three-dimensional (3D) whole-liver perfusion magnetic resonance (MR) imaging with parallel imaging, a novel imaging method to characterize tumor vascularization in vivo, has recently been applied to comprehensively image perfusion changes in large tumors. Coupled with new perfusion software, this technique enables motion correction, registration, and evaluation of perfusion MR parameters. The purpose of this study was to assess the feasibility of 3D whole-liver perfusion MR, for imaging hepatocellular carcinoma (HCC) and colorectal hepatic metastases (CRHM).

The efficacy of TACE combined sorafenib in advanced stages hepatocellullar carcinoma.

Background: The long-term survival in hepatocellullar carcinoma (HCC) patients after transarterial chemoembolization (TACE) remains dismal due to local and/or regional recurrence as well as distant metastasis. The efficacy of sorafenib in advanced HCC has been demonstrated and brought great hope. Recently, the use of sorafenib in combination with TACE for BCLC stage B and C HCC patients was recommended.
