BACKGROUND: Sentinel node navigation surgery (SNNS) in early gastric cancer (EGC) is technically feasible according to previous literature, however its long-term oncologic safety has not been reported. METHODS: A single-center, single-arm, phase II trial was conducted to determine the oncologic outcomes of laparoscopic sentinel node (SN) biopsy in clinical stage T1N0M0 gastric cancer patients. Cases with positive SNs on intraoperative pathologic examination underwent conventional gastrectomy with radical lymphadenectomy (SN-positive group), whereas those with negative SNs underwent laparoendoscopic-limited gastric resections without further lymph node dissections (SN-negative group)...

BACKGROUND: Delta-shaped anastomosis is usually applied for an intracorporeal gastrogastrostomy in totally laparoscopic pylorus-preserving gastrectomy (TLPPG). However, the remnant stomach is slightly twisted around the anastomosis because it connects in side-to-side fashion. To realize an intracorporeal end-to-end gastrogastrostomy using an endoscopic linear stapler, we invented a novel method including a unique anastomotic technique. MATERIALS AND METHODS: In this new approach, we first made small gastrotomies at the greater and lesser curvatures of the transected antrum and then pierced it using an endoscopic linear stapler...

The endoscopic and pathological features of early gastric mixed adenoneuroendocrine carcinoma (MANEC), as well as its carcinogenesis, remain largely unclear. Screening esophagogastroduodenoscopy was performed on an 80-year-old man, revealing 3 superficial elevated lesions. Endoscopic submucosal dissection (ESD) was performed, and the patient was diagnosed with intramucosal gastric cancer comprising mixed adenocarcinoma and neuroendocrine tumor, well-differentiated adenocarcinoma and well-differentiated adenocarcinoma, with negative margins...

Endoscopic submucosal dissection (ESD) of lesions using expanded indications for early gastric cancer (EGC) has been accepted as an alternative treatment for cases without lymph node metastasis. We herein report a rare case of metastatic lymph node tissue in mixed adenoneuroendocrine carcinoma (MANEC) after curative ESD using the expanded pathological criteria. A 70-year-old man underwent ESD for two EGC lesions. A pathological examination revealed lesions that required curative resection based on the expanded pathological criteria of the Japanese classification of gastric carcinoma...

Helicobacter pylori infection persists in more than half of the world's population and represents a risk factor for peptic ulcer disease and gastric cancer. Virulent strains of H. pylori carry a cag pathogenicity island (cagPAI), which encodes a type IV secretion system (T4SS) with the capability to inject the effector protein cytotoxin-associated gene A (CagA) into eukaryotic cells. Colonisation of the gastric epithelium by H. pylori provokes direct activation of the proinflammatory and survival factor nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB)...

BACKGROUND: Magnetically controlled capsule gastroscopy (MCCG) is a newly developed non-invasive method designed for gastric examination. Although favorable diagnostic accuracy has been reported, there is little if any data about its ability to diagnose gastric cancer. AIMS: To compare the detectability of superficial gastric neoplasia by MCCG and gastroscopy. METHODS: This study was a self-controlled comparison study. Ten subjects diagnosed with superficial gastric neoplasia and scheduled to undergo endoscopic submucosal dissection (ESD) at a tertiary hospital were prospectively invited for an MCCG examination...

BACKGROUND: Reduced-port laparoscopic gastrectomy further minimizes the invasiveness of laparoscopic gastrectomy, thereby improving patient quality of life. However, suboptimal ergonomics and visualization are challenges to performing reduced-port laparoscopy. As the application of a robotic surgical system may help overcome these challenges, the present study was performed to evaluate the short-term outcomes of reduced-port totally robotic distal subtotal gastrectomy. METHOD: An initial 40 consecutive gastric cancer patients treated with reduced-port totally robotic distal subtotal gastrectomy with lymph node dissection from February 2016 to February 2017 were retrospectively reviewed...

As one of the most important post-translational modifications (PTMs) of peptidome, glycopeptidome is closely related to serious disease, especially to cancer. In order to specifically discover and analyze glycopeptidome biomarkers for clinical diagnosis of cancer on early-stage, it is crucial to develop efficient technique to analyze low-abundance of endogenous glycopeptides in biological samples. In this report, a hydrophilic probe in mesoporous pore (denoted as Fe3 O4 @mSiO2 @G6P) was designed and prepared...

Advanced gastric cancer (AGC) has a high recurrence rate (especially peritoneal relapse) and a poor prognosis. Systematic chemotherapy or targeted therapy have not been able to significantly reduce the major cause of an unfavorable prognosis, namely the high peritoneal AGC recurrence rate post-surgery. Further studies concerning the application of hyperthermic intraperitoneal chemotherapy (HIPEC) post curative surgery for AGC patients, namely the prophylactic HIPEC (P-HIPEC), have involved a prophylactic approach to prevent peritoneal relapse following curative gastrectomy in high-risk patients...

Gastric stump cancer (GSC) is a carcinoma arising from the remnant stomach following gastric surgery for benign or malignant disease, and is more common in men. The risk of morbidity has an obvious time dependence. GSC incidence is likely to rise with lengthening of the initial operation interval. The GSC time interval after malignant disease is significantly shorter than that of benign disease. GSC etiologies mainly include duodenogastric reflux and denervation of the gastric mucosa resulting in the change of the gastric environment after gastrectomy and the Helicobacter pylori infection...

Due to different disease background of gastric stump cancer(GSC) patients (benign or malignant lesion, reconstruction of digestive tract, etc.), the GSC surgical procedure and the difficulty of lymphadenectomy are also different. The extent of radical lymphadenectomy for gastric stump cancer should extend beyond D2 lymphadenectomy, according to the different backgrounds of initial disease, reconstructions, and tumor location. A lymphadenectomy should include the lymph nodes in anterior (No.17) and posterior (No...

Gastric stump cancer was initially defined as a carcinoma of the stomach occurring more than 5 years after surgery for gastric or duodenal benign disease. In recent years, as the number of total gastrectomy for benign disease has gradually decreased and the gastric cancer detection and operation rate have annually increased, residual recurrence of primary gastric cancer more than 10 years after gastric cancer surgery has also been considered as gastric stump cancer. The incidence of gastric stump cancer is increasing annually...

Helicobacter pylori ( H. pylori ) infection is the most important risk factor for gastric cancer (GC) development through the Correa's gastric carcinogenesis cascade. However, H. pylori eradication alone does not eliminate GC, as pre-neoplastic lesions (atrophic gastritis, intestinal metaplasia and dysplasia) may have already developed in some patients. It is therefore necessary to identify patients at high-risk for gastric cancer after H. pylori eradication to streamline the management plan. If the patients have not undergone endoscopy with histologic assessment, the identification of certain clinical risk factors and non-invasive testing (serum pepsinogen) can predict the risk of atrophic gastritis...

Gastric cancer has high malignancy and early metastasis, which lead to poor survival rate. In this study, we assessed the expressions and prognostic values of MS4A family, a newly recently discovered family, by two online dataset, GEPIA and Kaplan Meier-plotter. From these results eight members, MS4A2, MS4A6, MS4A7, MS4A8, MS4A14, MS4A15, TMEM176A and TMEM176B showed positive expression in gastric cancer or normal tissues, and these genes were screened for further analysis of prognostic values. We observed that low mRNA expressions of MS4A2, MS4A7, MS4A14, MS4A15, TMEM176A and TMEM176B were correlated with better overall survival (OS) in all gastric cancer patients, while high mRNA expression of MS4A6 was observed to be associated with good prognosis...

Background and study aims  A 72-year-old man with complete situs inversus presented with early gastric cancer on the lesser curvature wall of the antrum of the stomach. Endoscopic submucosal dissection (ESD) was selected as a treatment. When the patient was positioned in the left decubitus position, the lesion was hidden by blood and gastric fluid because it was located on the gravitational side. Therefore, we decided to perform ESD with the patient in the right lateral decubitus position and use an inverted overtube, which provided a good endoscopic view without the need to rearrange the endoscopist, assistants, or endoscopic system...

Colorectal cancer (CRC) is a heterogeneous disease that is caused by the interaction of genetic and environmental factors. Although it is one of the most common cancers worldwide, CRC would be one of the most curable cancers if it is detected in the early stages. Molecular changes that occur in colorectal cancer may be categorized into three main groups: 1) Chromosomal Instability (CIN), 2) Microsatellite Instability (MSI), and 3) CpG Island Methylator phenotype (CIMP). Microsatellites, also known as Short Tandem Repeats (STRs) are small (1-6 base pairs) repeating stretches of DNA scattered throughout the entire genome and account for approximately 3 % of the human genome...
