“Linitis plastica (LP) is a distinct phenotype of gastric cancer. Macroscopically, it is characterized as a thickened stomach, with prominent diffusion of the tumor into the submucosal and muscular layers; microscopically, it is often associated with signet ring cell features and diffuse and scirrhous (referring to the histologic characteristic of abundant stromal cells) histologic types.”
“Linitis plastica due to gastric adenocarcinoma is a condition with a long history, but still lacks a standardized definition and is commonly confused with Borrmann type IV, Lauren diffuse, and signet-cell type gastric cancer. The absence of a clear definition is a problem when investigating its biological characteristics and role as a possible independent factor for prognosis. Nevertheless, the biological behavior for linitis plastica, which is unique, may be valuable in risk stratification and have implications for treatment. A definition of linitis plastica
based on molecular or genomic criteria could represent a useful starting point for investigating new targeted therapies.”
“The Siewert classification is widely used for determining which surgical procedure is used, because previous studies have shown that the pattern of lymph node (LN) metastasis depends on tumor location. In terms of surgical approaches for GEJ adenocarcinoma, a consensus was reached based on two randomized controlled trials. Siewert types I and III are treated as esophageal cancer and gastric cancer, respectively.”
“Gastric acid production is necessary for the body to digest food and break down nutritional components into absorbable amino acids, carbohydrates, and fats. Most of the acid is produced when gastric pH stimulates the release of gastrointestinal using the release and activation of various digestive enzymes. The stomach is a relatively acidic environment with a pH of less than 4.0, which can drop to 2.0 with parietal cells. Parietal cells live in the fundus and the body of the stomach and secrete hydrogen ions. This activity explains when this condition should be considered on a differential diagnosis, articulates how to properly evaluate for this condition, and highlights the role of the interprofessional team in caring for patients with this condition.”
“Acute upper gastrointestinal bleeding (AUGIB) is one of the most common emergencies in gastroenterology. Despite major improvements in its management, AUGIB continues to be associated with significant morbidity and mortality. Bleeding peptic ulcers are one of the principal causes of AUGIB. Endoscopic therapy to bleeding ulcers reduces further bleeding and improves patients’ outcomes”
“Neoadjuvant chemoradiotherapy (nCRT) followed by surgery is currently considered an important multimodality treatment option for patients with locally advanced esophageal or gastroesophageal junction cancer. Perioperative chemotherapy is an alternative multimodality treatment option for locally advanced gastroesophageal junction adenocarcinoma. The overall survival of patients with locally advanced esophageal or gastroesophageal junction cancer treated with nCRT followed by surgery remains relatively poor with an estimated 5-year OS rate of 40% to 50%, predominantly due to distant recurrences.”
“Patients with oesophageal cancer undergoing neoadjuvant chemoradiotherapy and surgery
are at substantial risk of thromboembolic and bleeding events throughout all stages of treatment. Survival is worse in patients with thromboembolic events during follow-up.”
