Double contrast-enhanced ultrasonography evaluation of preoperative Lauren classification of advanced gastric carcinoma
INTRODUCTION The clinical value of double contrast-enhanced ultrasonography (DCUS) in determining the Lauren classification of advanced gastric carcinoma needed investigation. MATERIAL AND METHODS Fifty-eight patients with gastric cancer proved by endoscopic biopsy underwent preoperative DCUS examination in which an oral contrast agent was combined with an intravenous agent, and the findings ...
متن کاملClinical Relevance of the Tumor Location-Modified Lauren Classification System of Gastric Cancer
PURPOSE The Lauren classification system is a very commonly used pathological classification system of gastric adenocarcinoma. A recent study proposed that the Lauren classification should be modified to include the anatomical location of the tumor. The resulting three types were found to differ significantly in terms of genomic expression profiles. This retrospective cohort study aimed to eval...
متن کاملIntratumoral and peritumoral lymphatic vessel density both correlate with lymph node metastasis in breast cancer
The status of lymph node involvement is an important prognostic factor for breast cancer. However, the presence of intratumoral lymphatic vessels in primary tumor lesions and the relationship between lymphatic vessel density (LVD) and lymph node metastasis (LNM) have not been firmly established. Therefore, we performed a meta-analysis study to investigate these issues. According to the pre-esta...
متن کاملPreoperative chemoradiotherapy for locally advanced gastric cancer
BACKGROUND To examine toxicity and outcomes for patients treated with preoperative chemoradiotherapy (CRT) for gastric cancer. METHODS Patients with gastroesophageal (GE) junction (Siewert type II and III) or gastric adenocarcinoma who underwent neoadjuvant CRT followed by planned surgical resection at Duke University between 1987 and 2009 were reviewed. Overall survival (OS), local control (...
متن کاملComparison of HER2 and Lauren Classification between Biopsy and Surgical Resection Samples, Primary and Metastatic Samples of Gastric Cancer
Purpose: Patients with advanced or metastatic adenocarcinoma of the stomach or esophagogastric junction for whom trastuzumab therapy is being considered, assessment for tumor human epidermal growth factor receptor-2 (HER2) status is necessary. Can the HER2 status and Lauren classification of the biopsy sample truly represent the HER2 status in the gastric cancer? Methods: Formalin-fixed, paraff...
