BACKGROUND Clinical significance of Notch1 activation in gastric cancer has been elucidated in our previous study, but the role of its ligands remains obscure. This study aims to evaluate the prognostic value of Jagged1 expression in patients with gastric cancer. METHODS We examined Jagged1 expression in tumor and nontumor tissues in retrospectively enrolled 302 patients with gastric cancer u...
Treatment options for patients with gastric cancer (GC) are based on tumor staging and resectability. Although only surgery provides improved survival, resection is contraindicated and should be avoided in the presence of intra-abdominal disease stage M1 (liver, peritoneal, or non-local lymph node metastases). Thus, a detailed and precise evaluation is imperative for optimal treatment. Staging ...
TNM (tumour, node, metastases) staging has thus far been the most important guide to prognosis in patients with gastric cancer. Histological grading, in contrast, has not provided any additional information. Recently a novel grading system based on tubular differentiation and mucus production has been proposed, which was correlated with patterns of tumour spread found at necropsy. This study se...
Introduction The extent of lymphadenectomy in the surgical treatment of gastric cancer is a topic of controversy among surgeons. This study was conducted to analyze the American National Cancer Database (NCDB) and conclude the optimal extent of lymphadenectomy for gastric adenocarcinoma. Methods The NCDB for gastric cancer was utilized. Patients who received at least a partial gastrectomy wer...
OBJECTIVE There is heterogeneity in the prognosis of gastric cancers staged according to the tumornodes- metastasis (TNM) system. This study evaluated the prognostic potential of an immune score system to supplement the TNM staging system. METHODS An immunohistochemical analysis was conducted to assess the density of T cells, B cells, and myeloid-derived suppressor cells (MDSCs) in cancer tis...
We aimed to explore the associations of polymorphisms in three microRNAs (miRNAs) (let-7e rs8111742, miR-365b rs121224 and miR-4795 rs1002765) that target PGC with the risk and prognosis of gastric cancer/atrophic gastritis. Sequenom's MassArray was used to genotype the miRNA polymorphisms in 724 gastric cancer cases, 862 atrophic gastritis cases and 862 controls in a Chinese population. We fou...
A real-time optical biopsy, which could determine tissue histopathology, would be of extraordinary benefit to staging laparoscopy for gastric cancer with serosal invasion (T4) that requires downstage treatment. We investigated the feasibility of using multiphoton imaging to perform a real-time optical diagnosis of gastric cancer with or without serosal invasion. First, a pilot study was perform...
