BACKGROUND:  Submucosal tunneling endoscopic resection (STER) has emerged as a feasible technique for resecting upper gastrointestinal (GI) tract submucosal tumors (SMTs) through natural orifice transluminal endoscopic surgery. STER reduces the risk of postoperative perforation and abdominal infections and promotes rapid wound healing. The aim of this meta-analysis was to evaluate the safety and efficacy of STER for small (≤ 3.5 cm) upper GI SMTs and explore the potential factors influencing STER's efficacy and complication rate...

INTRODUCTION:  Gastrointestinal stromal tumors (GISTs) are infrequently reported to cause gastroduodenal intussusception, especially in the cases with complete pylorus obstruction. GISTs comprise only 1 - 3 % of all gastrointestinal tract tumors, and most of them strongly express the c-KIT protein. Approximately 5 % of GISTs show negative staining of c-KIT. CASE PRESENTATION:  A 69-year-old man complained of acute abdominal pain accompanied with nausea and vomiting for 6 hours...

BACKGROUND The contemporary risk classification criteria of gastrointestinal stromal tumors (GISTs) may still have room to improve. The aim of our research was to analyze the impact factors for GIST patients' relapse-free survival (RFS). Furthermore, we explore whether gastrointestinal (1) bleeding will be a valuable indicator to predict GIST patients' prognosis. MATERIAL AND METHODS R0 resection GISTs patients were retrospectively enrolled during an 8-year period at West China Hospital of Sichuan University, and all patients' data were from the WCHSU-GIST database...

Epidemiology and evidence have demonstrated that colon carcinoma is one of the most common gastrointestinal tumors in the clinic. Reports have suggested that Tunicamycin significantly inhibits aggressiveness of colon carcinoma cells by promotion of apoptosis. In the present study, the inhibitory effect of tunicamycin on colon cancer cells and the potential underlying molecular mechanism was investigated. Western blotting, immunohistochemistry, apoptotic assays and immunofluorescence were used to analyze the therapeutic effects of tunicamycin on apoptosis, growth, aggressiveness and cell cycle of colon tumor cells, by downregulation of fibronectin, vimentin and E‑cadherin expression levels...

Collagen triple helix repeat containing 1 (Cthrc1) is a secreted protein that has been observed to lead to poorer prognosis by inducing the invasion and metastasis in different tumors; however, it has not been demonstrated that Cthrc1 is involved in tumor angiogenesis. Immunohistochemical staining of Cthrc1 and CD31 in gastrointestinal stromal tumor tissue demonstrated that Cthrc1 is associated with microvascular density. Overexpression of Cthrc1 protein may alter the properties of human umbilical vein endothelial cells (HUVECs), including migration, invasion, tubule formation and aortic ring sprouting...

The Full-Thickness Resection Device (FTRD; Ovesco Endoscopy, Tübingen, Germany) combines endoscopic full-thickness resection (EFTR) of gastrointestinal lesions with closure and cutting of the tissue in one integrated procedure. It provides en-bloc resection with an integral wall specimen for histopathological evaluation. This resection technique is partially filling of the gaps between the current procedures of choice in endoscopy (endoscopic mucosal resection and endoscopic submucosal dissection) and surgery...

We conducted a phase 1/2 study to evaluate the efficacy and safety of carbon ion radiotherapy (C-ion RT) with concurrent chemotherapy for locally advanced uterine cervical adenocarcinoma. Thirty-three patients were enrolled between April 2010 and March 2014. Treatment consisted of C-ion RT with concurrent weekly cisplatin at a dose of 40 mg/m2 . In the phase 1 component, the total dose was escalated from 68.0 Gy (relative biological effectiveness [RBE]) to 74.4 Gy (RBE) to determine the maximum tolerated dose of C-ion RT...

Although high-resolution three-dimensional imaging of endoscopically resected gastrointestinal specimens can help elucidating morphological features of gastrointestinal mucosa or tumor, there are no established methods to achieve this without breaking specimens apart. We evaluated the utility of transparency-enhancing technology for three-dimensional assessment of gastrointestinal mucosa in porcine models. Esophagus, stomach, and colon mucosa samples obtained from a sacrificed swine were formalin-fixed and paraffin-embedded, and subsequently deparaffinized for analysis...

Background and study aims:  Patients with malignant tumors of the upper gastrointestinal tract are at risk of weight loss. Early supportive nutrition therapy is therefore recommended and usually requires placement of a percutaneous endoscopic gastrostomy (PEG). The aim of this study was to compare adverse events and usage characteristics of the direct puncture technique with those of the traditional pull technique when used in patients with endoscopically passable tumors. The primary endpoint was the rate of inflammatory adverse events (AEs) at the gastrostomy fistula...

Recent progress in cancer genome analysis using next-generation sequencing has revealed a high mutation burden in some tumors. The particularly high rate of somatic mutation in these tumors correlates with the generation of neo-antigens capable of eliciting an immune response. Identification of hypermutated tumors is therefore clinically valuable for selecting patients suitable for immunotherapy treatment. There are several known causes of hypermutation in tumors, such as ultraviolet light in melanoma, tobacco smoke in lung cancer, and excessive APOBEC (apolipoprotein B mRNA editing enzyme, catalytic polypeptide-like) activity in breast and gastric cancer...

The transcription coregulators RIP140 and LCoR are part of a same complex which controls the activity of various transcription factors and cancer cell proliferation. In this study, we have investigated the expression of these two genes in human colorectal and gastric cancers by immunohistochemistry. In both types of tumors, the levels of RIP140 and LCoR appeared highly correlated. Their expression tended to decrease in colorectal cancer as compared to adjacent normal tissues but was found higher in gastric cancer as compared to normal stomach...

KIT kinase V559D mutation is the most prevalent primary gain-of-function mutation in Gastrointestinal Stromal Tumors (GISTs). Here we reported a highly selective KIT V559D inhibitor CHMFL-KIT-031, which displayed about 10-20 fold selectivity over KIT wt in the biochemical assay (IC50: 28 nM over 168 nM; Kd: 266 nM versus 6640 nM) and in cell (EC50: 176 nM versus 2000 nM for pY703) examination. It also displayed 15∼400-fold selectivity over other primary mutants such as L576P and secondary mutants including T670I, V654A (ATP binding pocket) as well as N822K and D816V (activation loop)...

The discovery of mutations in genes encoding the metabolic enzymes isocitrate dehydrogenase (IDH), succinate dehydrogenase (SDH), and fumarate hydratase (FH) has expanded our understanding not only of altered metabolic pathways but also epigenetic dysregulation in cancer. IDH1/2 mutations occur in enchondromas and chondrosarcomas in patients with the non-hereditary enchondromatosis syndromes Ollier disease and Maffucci syndrome and in sporadic tumors. IDH1/2 mutations result in excess production of the oncometabolite (D)-2-hydroxyglutarate...

Cardiac myxomas are rare tumors. Esophageal adenocarcinomas are common tumors of the gastrointestinal tract. Simultaneous occurrence of these tumors has not been reported. A 52-year-old gentleman presented to our hospital with dysphagia and was diagnosed with esophageal adenocarcinoma. Routine echocardiography discovered a cardiac tumor in the left atrium. The cardiac tumor was surgically removed and biopsy confirmed a myxoma. We removed the cardiac tumor as the first step and then initiated neoadjuvant chemotherapy...

BACKGROUND: In contrast to lung cancer, few precision treatments are available for colorectal cancer (CRC). One rapidly emerging treatment target in CRC is ERBB2 (human epidermal growth factor receptor 2 [HER2]). Oncogenic alterations in HER2, or its dimerization partner HER3, can underlie sensitivity to HER2-targeted therapies. METHODS: In this study, 8887 CRC cases were evaluated by comprehensive genomic profiling for genomic alterations in 315 cancer-related genes, tumor mutational burden, and microsatellite instability...

Gastric carcinoma (GC) is a common gastrointestinal malignancy with high incidence and mortality worldwide, and most patients are diagnosed in the late stages of disease. Palliative chemotherapy provides a survival benefit for patients with inoperable advanced GC. However, elderly patients who are unable to tolerate chemotherapy had worse prognosis due to lack of effective treatment. Herein we reported a Chinese elderly GC patient using next generation sequencing (NGS)-based tumor DNA analysis. Valuable gene variants of vascular endothelial growth factor (VEGF) A gene amplification were detected...

OBJECTIVE: Gastrointestinal stromal tumors (GISTs) are rare mesenchymal tumors of the gastrointestinal tract, which frequently cause intraabdominal metastases. The current standard of care is surgery for localized cases, and adjuvant imatinib is recommended for tumors with a high risk of recurrence. To date, radiotherapy has not been commonly accepted as a part of multimodality treatment approach other than palliation. However, recently published case reports and some small series suggest that radiotherapy is a valuable option for controlling locally progressive, drug-resistant disease...
