cancer of the stomach carries poor prognosis. surgery is the best treatment for gastric cancer. prediction of survival depends on the stage at the time of presentation. fluoroscopy, sonography, and computerized tomography are used for advanced gastric cancers staging, but they are not accurate enough to grade advanced gastric cancers. laparoscopic findings of lesions under direct vision, are ma...

OBJECTIVE The purpose of this study was to determine whether preoperative neoadjuvant therapy in patients with locally advanced pancreatic cancer affects the ability of multiphasic MDCT to predict successful surgical resection. MATERIALS AND METHODS From 2000 to 2006, there were 12 patients with prior neoadjuvant therapy successfully downstaged by CT and 31 age-matched pancreatic cancer patie...

BACKGROUND To examine the predictive value of tumor markers for evaluating tumor resectability in patients with hilar cholangiocarcinoma and to explore the prognostic effect of various preoperative factors on resectability in patients with potentially resectable tumors. Patients with potentially resectable tumors judged by radiologic examination were included. The receiver operating characteris...

Objectives. To evaluate, in hilar cholangiocarcinoma (HCCA), the prognostic impact of specific preoperative radiologic parameters on resectability, metastases, and yield of laparoscopy, and to evaluate the currently used staging systems. Methods. Consecutive patients with HCCA presenting in our center from January 2003 through August 2010 were evaluated. Suspicion on lymph node metastasis, port...

CONTEXT The optimal approach to pre-operative imaging assessment of pancreatic cancer is unknown. OBJECTIVE The aim of this meta-analysis was to assess accuracy and performance characteristics of EUS in determining nodal staging, vascular invasion, and prediction of resectability of pancreatic cancer. A secondary aim was to perform head to head comparison of performance characteristics betwee...

The role of integrated (18)F-2-fluoro-2-deoxy-D-glucose positron emission tomography computed tomography (PET-CT) is uncertain in gallbladder cancer. The aim of this study was to show the role of PET-CT in gallbladder cancer patients. Fifty-three patients with gallbladder cancer underwent preoperative computed tomography (CT) and PET-CT scans. Their medical records were retrospectively reviewed...

BACKGROUND Computed tomography (CT) is widely used to pre-operatively evaluate patients with pancreatic tumors. AIM The purpose of this study is to evaluate retrospectively, the ability of multi-detector computed tomography (MDCT) to predict resectability of pancreatic cancer on the basis of surgical outcome and pathologic correlation. PATIENTS AND METHODS Sixty nine consecutive patients pr...

OBJECTIVE To assess the use of contrast-enhanced magnetic resonance imaging (CEMRI) in addition to computed tomography in the pre-operative assessment of patients for radical surgery in malignant pleural mesothelioma. METHODS Over a 45-month period, 51 of 76 patients assessed (69 men and seven women), underwent extra-pleural pneumonectomy or radical pleurectomy/decortication. Post-operative p...
