Objective: The objective of this study was to summarize the accuracy of preoperative vascular invasion with endoscopic ultrasound (EUS) and computed tomography (CT) test performance in pancreatic cancer with meta-analysis

Method: Two reviewers searched MEDLINE database to identify relevant studies. The reference lists of the trials were manually searched. Included studies used surgical and/or histological findings as the "gold standard," and provided sufficient data to construct a diagnostic 2 × 2 table.

Background/aims: The purpose of this study was to evaluate the effect of matrix metalloproteinase-9 overexpression on clinical outcome of gastric cancer using a meta-analysis.

Methodology: Relevant studies concerning the association between Matrix metalloproteinase-9 expression and survival of patients with gastric cancer were collected from electronic databases. Hazard ratios (HRs) with 95% confidence intervals (Cls) were calculated to estimate the association.

Pancreatic ductal adenocarcinoma (PDAC) is a lethal cancer with a poor prognosis. Our previous proteomic analysis found apolipoprotein E (ApoE) protein to be up-regulated in the sera of patients with PDAC. In this study, we sought to confirm this finding and investigate the relationship between ApoE and PDAC.

Objective: To identify protein markers for the early diagnosis of pancreatic cancer by a comparative proteomic method.

Methods: Comparative analysis on the pancreatic peripheral blood protein profiling from 20 pancreatic cancer patients, 10 chronic pancreatitis patients and 20 cancer-free controls from May 2007 to September 2008 was carried out by two-dimensional fluorescence electrophoresis (2D-DIGE). Differentially expressed proteins were identified by matrix-assisted laser desorption/ionization time of flight mass spectrometry (MALDI-TOF-MS).

Purpose: Pancreatic ductal adenocarcinoma (PDAC) is one of the most lethal cancers worldwide and is difficult to detect at its early stages when treatment is most effective. Therefore, we performed a comparative proteomic study to identify new biomarkers for the detection of PDAC.

Methods: Serum samples from patients with PDAC, chronic pancreatitis and normal controls were compared using two-dimensional difference gel electrophoresis (2D-DIGE).
