BACKGROUND: Efforts to address the poor prognosis associated with esophageal adenocarcinoma (EAC) have been hampered by a lack of biomarkers to identify early disease and therapeutic targets. Despite extensive efforts to understand the somatic mutations associated with EAC over the past decade, a gap remains in understanding how the atlas of genomic aberrations in this cancer impacts the proteome and which somatic variants are of importance for the disease phenotype. METHODS: We performed a quantitative proteomic analysis of 23 EACs and matched adjacent normal esophageal and gastric tissues...

BACKGROUND AND AIM: Cystic dilatation of the gastric glands within the mucosal layer is the hallmark of the rare condition known as gastritis cystica profunda (GCP). Although it has been proved that GCP is the precursor lesion for early gastric cancer (EGC), the management strategy of GCP-related EGC is not well established.The purpose of this research was to determine if ESD is effective and safe for GCP-related EGC. METHODS: Patients with EGC who had ESD at Beijing Friendship Hospital between January 2015 and May 2023 were retrospectively included...

BACKGROUND AND OBJECTIVE: Gastroesophageal junction (GEJ) cancer is a highly morbid disease with a poor prognosis. While uncommon in the United States, globally it is ranked as the sixth or seventh most common cancer depending on survey tool. GEJ cancer presents a unique and challenging symptom profile for patients at all disease stages, regardless of histology. Even patients with early stage disease experience debilitating cancer-related symptoms and treatment side effects. The heavy symptom burden associated with this disease includes dysphagia, nausea and vomiting, pain, anxiety, depression and malnutrition...

Precise early diagnosis and staging are conducive to improving the prognosis of colorectal cancer (CRC) and gastric cancer (GC) patients. However, due to intrusive inspections and limited sensitivity, the prevailing diagnostic methods impede precisely large-scale screening. In this work, we reported a high-throughput serum metabolic patterns (SMP) screening strategy based on covalent organic frameworks-assisted laser desorption/ionization mass spectrometry (hf-COFsLDI-MS) for early diagnosis and staging of CRC and GC...

OBJECTIVE: To explore the core genes related to the diagnosis and prognosis of gastric cancer (GC) based on Gene Expression Omnibus (GEO) database and screen the molecular targets involved in the occurrence and development of GC. METHODS: GC microarray data GSE118916, GSE54129 and GSE79973 were downloaded from GEO database, and the differentially expressed genes (DEGs) were screened. Enrichment analysis of the signaling pathways and molecular functions were preformed and protein-protein interaction networks (PPI) were constructed to identify the hub genes, whose expression levels and diagnostic and prognostic values were verifies based on gastric adenocarcinoma data from TCGA...

Early gastric cancer (EGC) refers to malignant tumor lesions that are limited to the mucosa and submucosa layers, regardless of the presence of lymph node metastasis. Typically, EGC has a low rate of perigastric lymph node metastasis, and long-term survival outcomes are good after radical surgical treatment. The primary objective of surgical treatment for EGC is to achieve functional preservation while ensuring a radical cure. Sentinel node navigation surgery (SNNS) is a surgical technique used in the treatment of EGC...

BACKGROUND: Tracheal injury is a rare but potentially serious acute complication of endotracheal intubation. Very few cases of tracheal injury associated with coagulation abnormalities have been reported in the literature. We present a rare case of a patient presenting with tracheal injury in combination with coagulation abnormalities following thyroidectomy. CASE PRESENTATION: A 58-year-old woman with a history of postoperative chemotherapy for breast cancer, gastric polyps, multiple colonic polyps, esophageal papillary adenomas, and thyroid adenomas presented with dyspnea following 10 ml hemoptysis on the third day after thyroidectomy; she was admitted to the intensive care unit and underwent tracheal intubation for maintaining the airway...

Although rare, there is ongoing research into biomarkers that predict the onset and recurrence of gastric cancer, particularly focusing on substances found in exosomes. Long non-coding RNAs (lncRNAs) have garnered attention for their potential in diagnosing gastric cancer. This study investigates the role of lncRNAs in gastric cancer, focusing on their presence in exosomes as potential biomarkers for the disease's onset and recurrence. We utilized the ArrayStar Human LncRNA array 2.0 to analyze lncRNA expression in tissues from early-stage gastric cancer patients...

CASE DESCRIPTION: A 45-year-old female with gastric adenocarcinoma was started on capecitabine-oxaliplatin chemotherapy one week before presenting to the emergency department with weakness. Blood pressure was 78/56 mmHg, heart rate 140 bpm and oxygen saturation 85%...

The noninvasive detection technique using serum for large-scale screening is useful for the early diagnosis of gastric cancer (GC). Herein, we employed liquid chromatography mass spectrometry to determine the serum proteome signatures and related pathways in individuals with gastric precancerous (pre-GC) lesions and GC and explore the effect of Helicobacter pylori ( H. pylori ) infection. Differentially expressed proteins in GC and pre-GC compared with non-atrophic gastritis (NAG) group were identified. APOA4, a protein associated with metaplastic differentiation, and COMP, an extracellular matrix protein, were increased in the serum of patients with pre-GC lesions and GC...

BACKGROUND: 5-Hydroxymethylcytosine-enriched gene profiles and regions show tissue-specific and tumor specific. There is a potential value to explore cell-free DNA 5-hydroxymethylcytosine feature biomarkers for early gastric cancer detection. METHODS: A matched case‒control study design with 50 gastric cancer patients and 50 controls was performed to sequence the different 5-hydroxymethylcytosine modification features of cell free DNA. Significantly differential 5-hydroxymethylcytosine modification genes were identified to construct a gastric cancer diagnostic model...

BACKGROUND: Endoscopic submucosal dissection (ESD) has been recommended as the first-line treatment for early gastric cancer (EGC). However, poor visualization of the operative field increases both the procedure time and the risk of complications, especially for large and difficult lesions. We introduced a novel technique, magnetic anchor-guided ESD (MAG-ESD) and compared it with conventional ESD (C-ESD) for the treatment of large EGCs in terms of efficacy, safety, and advantages. METHODS: Patients with large EGCs who underwent MAG-ESD or C-ESD at the First Affiliated Hospital of Xi'an Jiaotong University from March 2020 to March 2022 were retrospectively enrolled in this study...
