This study aimed to evaluate the utility of optical enhancement (OE) in early gastric cancer demarcation. Twenty lesions of early gastric cancer were examined by PENTAX endoscopy system with OE-1 and OE-2 functions. The areas of tumor demarcation identified by 12 evaluators (6 novice and 6 experienced) were compared to the corresponding correct areas determined by postoperative histopathology findings. The misdiagnosed scores that were the sums of false-positive and false-negative areas were compared. Color of one hundred pixels from the inside of the cancerous area and the outside of the cancerous area was expressed as three-dimensional RGB component vectors...

Gastric intestinal metaplasia (GIM) is a high risk for intestinal type gastric cancer; however, there is a limitation for detection of GIM using white light imaging (WLI). Image-enhanced endoscopy (IEE) is more advantageous than WLI for optical diagnosis of GIM (1). Linked color imaging (LCI) (FUJIFILM Co., Tokyo, Japan) was newly developed for advanced IEE and enables visualization of red lesions that appear redder and whitish red lesions that appear whiter during routine endoscopy (2). GIM is observed as a lavender color that is distinguishable from the circumferential mucosa without GIM by using LCI (Figure 1)...

A 63-year-old man with dysphagia was referred to our hospital. He was found to have a type 2 tumor extending from the lower thoracic esophagus to the esophagogastric junction via upper gastrointestinal endoscopy. A biopsy revealed adenocarcinoma with overexpression of the human epidermal growth factor type 2(HER2). The tumor was type I according to Siewert's classification, as the epicenter of the tumor was 27mm to the oral side from the esophago-gastric junction. The clinical diagnosis was T3N1M1, stage IV according to the Japanese Classification of Gastric Carcinoma, and T3N2M0, stage III per the Japanese Classification of Esophageal Cancer...

Background and study aims: In the Western world, gastric cancer (GC) usually presents at an advanced stage, carrying a high mortality rate. Studies have reported that 14 % to 26 % of GCs are missed at endoscopy up to 3 years before diagnosis. Systematic Alphanumeric Coded Endoscopy (SACE) has been proposed to improve quality of esophagogastroduodenoscopy (EGD) by facilitating a complete examination of the upper gastrointestinal tract. This prospective cross-sectional study was designed to determine the frequency of gastric intraepithelial neoplasia (GIN) by using the SACE approach in cohort of patients from low socioeconomic level...

Gastric metastasis is rare but it can be the initial symptom of cancer. The second leading cause of this type of metastasis is breast cancer. A lack of clinical signs and nonspecific side effects of the treatment of primary tumors can lead to the misdiagnosis of metastatic gastric cancer. Upper gastrointestinal endoscopy with biopsy and immunohistochemistry should be used for diagnosis. Treatment is palliative; it includes chemo, endocrine, and radiation therapies. Four patients with breast cancer and gastric metastasis were identified...

Methodology for the diagnosis and staging of early gastric cancer (EGC) has improved in Japan since the development of the gastro-camera and determination of a definition of EGC. Imaging technology has been steadily evolving in the endoscopy field. Improvements in the resolution of standard endoscopy images used in screening and surveillance provide greater opportunities to find gastric cancer earlier. Image enhancement endoscopy (IEE), such as narrow band imaging (NBI), highlights mucosal structures and vascularity...

In 2015, the Japanese government decided to introduce endoscopic screening for gastric cancer as a national program. To provide endoscopic screening nationwide, we estimated the proportion of increase in the number of endoscopic examinations with the introduction of endoscopic screening based on a national survey. The total number of endoscopic examinations has increased, particularly in clinics. Based on the national survey, the total number of participants in gastric cancer screening was 3,784,967. If 30% of the participants are switched from radiographic screening to endoscopic screening, about 1 million additional endoscopic examinations are needed...

BACKGROUND: Gastric cancer is a heterogeneous malignant disease associated with environmental and genetic predisposing factors. While gastric cancer incidence and mortality fell greatly globally over the past decades, it remains the fourth cause of cancer-related death worldwide. Thus, prevention of gastric cancer is still a major strategy for improvement of gastric cancer prognosis. SUMMARY: Helicobacter pylori infection has been demonstrated to be a major risk factor for the development of gastric cancer...

Follow-up after gastrectomy for gastric cancer has several purposes, including management of side effects of surgery, oncological recurrence surveillance, psychological support, and data collection for research. How follow-up after gastrectomy, and especially recurrence surveillance, is performed differs immensely between different Western countries, despite guidelines from Western oncological organizations quite unanimously advocating symptom-driven surveillance, without scheduled cross-sectional imaging, endoscopies, or analysis of tumor markers...

BACKGROUND: The rate for upper gastrointestinal (UGI) cancers, and especially the rate for gastric cancer, varies from country to country and from region to region within country. In Turkey, the incidence of gastric cancer varies widely among regions due to the diverse cultures and accompanying food habits of the population. This study aimed to determine the endoscopic frequency of esophageal and gastric cancers and the usefulness of alarm symptoms in diagnosing gastric cancer in subjects undergoing endoscopy in northeastern Turkey...

Recent meta-analyses and a prospective multicenter trial of sentinel node (SN) mapping in early gastric cancer have demonstrated acceptable SN detection rates and accuracy of determination of lymph node status. SN mapping may play a key role in obtaining individual metastatic information. It also allows modification of surgical procedures, including function-preserving gastrectomy in patients with early gastric cancer. A dual-tracer method that uses radioactive colloids and blue dye is currently considered the most reliable method for the stable detection of SNs in patients with early gastric cancer...

It has been shown that metastases to the thyroid from extrathyroidal malignancies occur as solitary or multiple nodules, or may involve the whole thyroid gland diffusely. However, diffuse metastasis of gastric cancer to the thyroid is extremely rare. Here, we report a case of a 74-year-old woman with diffuse infiltration of gastric adenocarcinoma (signet-ring-cell carcinoma/poorly differentiated adenocarcinoma) cells in the thyroid. The pathological diagnosis was made based on upper gastrointestinal endoscopy with biopsy and fine-needle aspiration cytology of the thyroid...

OBJECTIVE: Early gastric cancer (EGC) is defined as cancer invasion confined to the mucosa or submucosa, irrespective of lymph node metastasis. Recently endoscopic submucosal dissection (ESD) has been widely accepted for the treatment for dysplasia and EGC without lymph node metastases. While the method has been advanced in Far East countries, ESD is still being developed in Europe and has not gained enough popularity although it has been recommended as the treatment of choice for superficial gastric neoplastic lesions by European Society of Gastrointestinal Endoscopy (ESGE) in 2015...

PURPOSE OF REVIEW: Gastric cancer remains a leading cause of mortality worldwide and gastroenterologists are playing an increasingly larger role in its management. This article reviews the endoscopic management of gastric cancer, with emphasis on recent advances in the field. RECENT FINDINGS: Long-term studies comparing surgery and endoscopic resection for early gastric cancer have shown no difference in 10-year survival rates. Second-look endoscopy, performed 2 days after endoscopic submucosal dissection (ESD) to address the concern of delayed bleeding, may not affect rebleeding rates...

An 80-year-old man who had undergone distal gastrectomy and Billroth-II gastrojejunostomy 38 years previously, for a benign gastric ulcer, was diagnosed with remnant gastric cancer based on upper gastrointestinal endoscopy findings. He presented at our emergency department with acute-onset epigastric pain due to perforated remnant gastric cancer. Conservative medical management was selected, including nasogastric tube insertion, antibiotics, and proton pump inhibitors, because his peritonitis was limited to his epigastrium and his general condition was stable...
