Objective: To explore the clinical features, diagnosis, treatment and prognosis of primary hepatic angiosarcoma (PHA).

Methods: The clinical data of 7 PHA patients admitted to our hospital from December 2004 to December 2010 were retrospectively analyzed and the relevant literatures reviewed.

Results: Seven cases (5 males and 2 females) were diagnosed as PHA among 1027 (0.

Objective: To summarize the experience of hepatectomy in patients with hepatocellular carcinoma fulfilling the Milan criteria and analyze the clinicopathological factors for patient survival and tumor recurrence.

Methods: The clinicopathological data of 104 patients with early-stage hepatocellular carcinoma fulfilling the Milan criteria and underwent hepatectomy at Peking Union Medical College Hospital between April 2003 and June 2009 were retrospectively analyzed.

Results: The median follow-up was 24 months.

Objective: Pancreatic metastasis from renal cell carcinoma (RCC) is a rare event and has not been reported in our country. We report a series of 3 patients with metastatic RCC to the pancreas after radical nephrectomy at our institution. The published reports in the literature were reviewed, and the diagnosis, treatment as well as prognosis of this rare event were discussed.

Article Synopsis
  • The study aims to identify the timing and risk factors for recurrence of hepatocellular carcinoma (HCC) after surgical resection.
  • The research involved 94 patients categorized by recurrence timing, with findings indicating recurrence rates of 30.9% at 6 months and 36.2% at 1 year, linked to previous multifocal HCC presentations.
  • Digital subtraction angiography (DSA) was shown to be an effective diagnostic tool, helping in the early detection and management of intra-hepatic recurrence.

Article Synopsis
  • A new three-dimensional liver function evaluation system using 99mTc-EHIDA scintigraphy has been developed to assess liver function before and after surgery.
  • The study included 16 patients with liver lesions, and significant differences were found in liver function indicators between those with cirrhosis and those without.
  • The results suggest that this new evaluation system could enhance the understanding of liver surgery risks, as certain indices correlated well with liver function tests and postoperative outcomes.

Objective: To summarize the surgical experiences, risks, complications, and managements for hepatic masses in difficult sites.

Methods: Totally 47 patients were divided into three groups based on the liver tumor sites: primary porta hepatis group, secondary porta hepatis group, and caudate lobe group. All patients underwent different portion of hepatectomy.

Background: Radical major hepatectomy (RMH) has been suggested as one of main options for cure of large/advanced hepatocellular carcinoma (HCC). However, its operative risk remains high and its effectiveness is still controversial, especially for patients with liver cirrhosis. The present study aims to investigate short- and long-term outcomes and to identify prognostic factors for cirrhotic patients with HCC after RMH.

Background And Objectives: Curative hepatic resection (CHR) was a modality that provides possibility of long-term survival for hepatocellular carcinoma (HCC). So far, prognostic factors of male patients with HCC after CHR remain unclear. Purposes of the present study were to identify these factors and to compare them with those for females.

Induction of p53 gene expression in cancer cells can lead to both cell cycle arrest and apoptosis. To clarify whether the level of p53 expression determines the apoptotic response of hepatocellular carcinoma (HCC) cells, we assessed the effect of various levels of expression of p53 gene on a p53-deficient HCC cell line, Hep3B, utilizing a doxycycline (Dox)-regulated inducible p53 expression system. Our results showed that apoptosis was induced in HCC cells with high levels of p53 expression.

p53 is important in the development of hepatocellular carcinoma (HCC) and in therapeutic approaches, but the mechanism whereby it inhibits HCC growth is still unclear. The aim of the present study was to establish a HCC cell system in which p53 levels can be regulated. Full-length wild-type p53 cDNA obtained by PCR was cloned into a retroviral response vector controlled by the tetracycline responsive element (RevTRE-p53).

Eicosapentaenoic acid (EPA) has been demonstrated to induce apoptosis and cell cycle arrest in various cancer cell lines in vitro. In this study, we investigated the anti-tumor effects of EPA on hepatoma cell lines and the mechanisms responsible for induced cell death. Three hepatoma cell lines tested had different p53 status: HepG2 with a wild-type p53; Hep3B, of which the endogenous p53 was deleted; and Huh7 with its p53 mutated.
