Establishing prognostic models for intrahepatic cholangiocarcinoma based on immune cells.

Background: Intrahepatic cholangiocarcinoma (ICC) is a malignant liver tumor that is challenging to treat and manage and current prognostic models for the disease are inefficient or ineffective. Tumor-associated immune cells are critical for tumor development and progression. The main goal of this study was to establish models based on tumor-associated immune cells for predicting the overall survival of patients undergoing surgery for ICC.

Outcomes of intrahepatic cholangiocarcinoma with portal vein tumor thrombus following hepatic resection.

Background And Aim: Portal vein tumor thrombus (PVTT) is not commonly used in the treatment of intrahepatic cholangiocarcinoma (ICC), and its impact on the prognosis of ICC is unclear. We aimed to assess the outcomes of ICC with or without PVTT after hepatic resection.

Methods: From January 2000 to December 2005, the data from all consecutive patients with ICC who underwent hepatic resection at our hospital were retrospectively analyzed.

Postoperative Adjuvant Transcatheter Arterial Chemoembolization After R0 Hepatectomy Improves Outcomes of Patients Who have Hepatocellular Carcinoma with Microvascular Invasion.

Background: Microvascular invasion (MiVI) is a major risk factor of survival outcomes after curative resection for patients with hepatocellular carcinoma (HCC). This study aimed to investigate the impact of postoperative adjuvant transcatheter arterial chemoembolization (PA-TACE) on HCC patients with MiVI.

Methods: From January 2004 to June 2013, HCC patients with histologically confirmed MiVI and well-tolerated liver function who underwent PA-TACE after R0 hepatectomy (RH) or RH alone were studied retrospectively.

A splicing variant of Merlin promotes metastasis in hepatocellular carcinoma.

Merlin, which is encoded by the tumour suppressor gene Nf2, plays a crucial role in tumorigenesis and metastasis. However, little is known about the functional importance of Merlin splicing forms. In this study, we show that Merlin is present at low levels in human hepatocellular carcinoma (HCC), particularly in metastatic tumours, where it is associated with a poor prognosis.

Development and evaluation of immunoassay for zeranol in bovine urine.

A high affinity polyclonal antibody-based enzyme linked immunosorbent assay (ELISA) was developed for the quantification of zeranol in bovine urine. On the basis of urine matrix studies, the optimized dilution factors producing insignificant matrix interference were selected as 1:5 in pretreatment. In the improved ELISA, the linear response range was between 0.
