Gastric cancer is one of the leading causes of cancer-related deaths worldwide. Despite the advanced surgical resection techniques and anticancer drugs currently available to treat early stage gastric cancer, the prognosis of patients with gastric cancer remains poor. The epithelial to mesenchymal transition (EMT) is an important process for the initiation of tumorigenesis. Recent studies suggested that reactive oxygen species (ROS) can promote cell migration and invasion. Thus, an imbalance of redox homeostasis can result in cancer cells exhibiting EMT properties...

PURPOSE: Gastric cancer (GC) is still one of the most common malignancies with the majority of the tumors diagnosed at advanced stage. The need for identification of prognostic and early detection biomarkers is thus compulsory. Claudins are biomarkers that are currently evaluated in the literature in the frame of epithelial-mesenchymal transition. The purpose of this investigation was to study the expression of claudin-4 in the various histological subtypes of GC and to evaluate its prognostic value...

Peritoneal metastasis of gastric cancer is the main cause of death in gastric cancer patients. Peritoneal metastasis of gastric cancer is difficult to diagnose in its early stage due to lack of obvious clinical signs and symptoms, and poor treatment outcomes and prognosis are often associated with late stage peritoneal metastasis. Therefore, it is crucial to utilize effective early diagnostic tools and to improve the long-term outcomes and the prognosis of patients with advanced gastric cancer. Recently, systemic chemotherapy and intraperitoneal chemotherapy are the first line therapy, and cytoreductive operation plus abdominal cavity thermochemotherapy may be the best method in the treatment of peritoneal metastasis...

Enhanced recovery after surgery (ERAS) has been rapidly developing by combining several techniques with evidence-based adjustments, including preoperative education, preoperative carbohydrate loading, epidural or regional anesthesia, early initiation of enteral nutrition, ambulation and multi-modal pain management. The core part of ERAS is to reduce and reverse surgical stress and therefore greatly improve clinical outcome. Under the guidance of ERAS, perioperative management of robotic gastric cancer operation should follow the basic principles of ERAS and clinical pathway to maximize the advantages of the robotic surgery...

The World Health Organization (WHO) has declared gastric carcinoma a global health concern and gastric cancer remains the third leading cause of cancer deaths worldwide. With the rising incidence of gastric cancer, a body of both retrospective and randomized data has emerged since the early 1990's evaluating the role of minimally invasive platforms in the management of gastric cancer. While Eastern studies have shown that the laparoscopic approach is safe and feasible for advanced gastric cancer in Eastern patients, it is not clear whether this is true for patients in the West...

We try to explore the value of aberrant DNA methylation of several cancer-related genes in plasma as non-invasive biomarkers for gastric cancer (GC) and precancerous lesions. By using methylation-specific polymerase chain reaction assay we determined the methylation status of three selected genes ZIC1, HOXD10 and RUNX3 in blood samples from patients with GC and precancerous lesions. We discovered that the methylation rate of ZIC1, HOXD10 and RUNX3 increased significantly in the progression of gastric carcinogenesis...

BACKGROUND & AIMS: Early-onset gastric cancer, which develops in younger patients than most gastric cancers, is usually detected at advanced stages, has diffuse histologic features, and occurs more frequently in women. We investigated somatic genomic alterations associated with the unique characteristics of sporadic diffuse gastric cancers (DGCs) from younger patients. METHODS: We conducted whole exome and RNA sequence analyses of 80 resected DGC samples from patients 45 years old or younger in Korea...

Gastric cancer (GC) is the fifth most common type of malignancy and the third leading cause of cancer-associated mortality worldwide. It is necessary to identify novel methods aimed at improving the early diagnosis and treatment of GC. MicroRNA expression profiles in the plasma of patients with GC have demonstrated a potential use in the opportune diagnosis of this neoplasm. However, there are currently no standardized targets for use in the normalization of microRNA Cq values for different neoplasms. The present study tested two normalization approaches while analyzing plasma derived from patients with GC and non-atrophic gastritis...

BACKGROUND: Limited data exist that describe the long-term outcomes from additional surgery following non-curative endoscopic resection (ER) of early gastric cancer (EGC) in older people. This study aimed to determine the appropriate treatment strategy for these patients. METHODS: We analyzed data from 2895 patients who underwent ER for EGC, of whom 451 (15.6%) had non-curative resections followed by curative surgery or surveillance only. Of these patients, 138 were older (aged ≥70 years)...

Lymph node metastasis is one of the most important prognostic factors in patients with gastric cancer. An inadequate number of dissected lymph nodes is an independent risk factor affecting recurrence, even in patients who are node negative. Oddly, certain early-stage patients still experience recurrence or metastasis within a short time, even if they have undergone standard radical mastectomy. Many researchers have attributed these adverse events to lymph node micrometastasis (LNM), which is defined as a microscopic deposit of malignant cells of less than 2 mm in diameter...

Gastric cancer is a deadly malignancy afflicting close to a million people worldwide. Patient survival is poor and largely due to late diagnosis and suboptimal therapies. Disease heterogeneity is a substantial obstacle, underscoring the need for precision treatment strategies. Studies have identified different subgroups of gastric cancer displaying not just genetic, but also distinct epigenetic hallmarks. Accumulating evidence suggests that epigenetic abnormalities in gastric cancer are not mere bystander events, but rather promote carcinogenesis through active mechanisms...

BACKGROUND: Recent technical improvements allow safe laparoscopic lymph node dissection (LND) in gastric cancer.1 (,) 2 In suprapancreatic LND, careful LND around the celiac artery (CA) is essential. From a patient's right side, deep LND is performed around the right side of the CA after dissecting around the common hepatic artery (CHA). For LND around the left side of the CA on the same operative axis as the right side, we developed a new procedure for LND along the proximal splenic artery (SA), performed from the patient's left side...

Classical cadherins are the key molecules that control cell-cell adhesion. Notwithstanding this function, it is also clear that classical cadherins are more than just the "glue" that keeps the cells together. Cadherins are essential regulators of tissue homeostasis that govern multiple facets of cellular function and development, by transducing adhesive signals to a complex network of signaling effectors and transcriptional programs. In cancer, cadherins are often inactivated or functionally inhibited, resulting in disease development and/or progression...

The inflammatory response is known to have a significant role in certain autoimmune diseases and malignancies. We review current knowledge regarding the functions of activator protein 1 (AP-1) as an important modulator in several immune disorders and carcinomas. AP-1 is overexpressed in rheumatoid arthritis and in long-term allogeneic hematopoietic stem cell transplantation survivors; however, decreased expression of AP-1 has been observed in psoriasis, systematic lupus erythematosus and in patients who do not survive after hematopoietic stem cell transplantation...
