BACKGROUND: The plasticity of cancer stem cells (CSCs)/tumor-initiating cells (T-ICs) suggests that multiple CSC/T-IC subpopulations exist within a tumor and that multiple oncogenic pathways collaborate to maintain the CSC/T-IC state. Here, we aimed to identify potential therapeutic targets that concomitantly regulate multiple T-IC subpopulations and CSC/T-IC-associated pathways. METHODS: A chemoresistant patient-derived xenograft (PDX) model of human esophageal squamous cell carcinoma (ESCC) was employed to identify microRNAs that contribute to ESCC aggressiveness...

BACKGROUND: Self-expandable metal stent (SEMS) insertion and percutaneous gastrostomy (PG) feeding are commonly used for patients with esophageal cancer and dysphagia. This study aimed to compare outcomes between SEMS insertion and PG feeding for them. METHODS: We retrospectively analyzed 308 patients with esophageal cancer who underwent fully covered SEMS insertion (stent group) or PG (gastrostomy group) for dysphagia due to tumor. Patients with other causes of dysphagia, such as radiation-induced or postoperative stricture, were excluded from the study...

BACKGROUND: Though normally linked to bone and cartilage development, the Runt-related transcription factor, RUNX2, was reported in the mouse heart during development of the valves. We examined RUNX2 expression and function in the developing avian heart as it related to the epithelial-mesenchymal transition (EMT) in the atrioventricular canal. EMT can be separated into an activation stage involving hypertrophy and cell separation and an invasion stage where cells invade the extracellular matrix...

Autophagy is a highly conserved process by which the cell contents are delivered to lysosomes for degradation, or are used to provide macromolecules for energy generation under conditions of nutritional starvation. It has previously been demonstrated that cancer cells in hypoxic regions, with an oxygen concentration below the normal physiological level, express hypoxia inducible factor (HIF)‑1α, in order to adapt and survive. HIF‑1α is important in the regulation of oxygen homeostasis and the transcription of hundreds of genes in response to conditions of hypoxia, hence maintaining energy and redox homeostasis...

Esophageal metastasis from colorectal carcinoma is uncommon, and diagnosis of esophageal metastasis is difficult. We report a case of a 54-year-old woman with postoperative recurrence of rectal cancer metastasizing to the esophagus. She underwent rectectomy and adjuvant chemotherapy with fluorouracil, leucovorin plus oxaliplatin for stage IIIB rectal cancer. Three years later, she presented with dysphagia and cough. Computed tomography showed thickening of the esophagus wall, enlargement of the lymph nodes in the mediastinum and abdomen, and ground-glass opacities in the right lung...

Although it has long been appreciated that p300 acts as a critical Notch coactivator, the mechanistic details of p300 in Notch-mediated transcription remain unclear. We previously demonstrated that PEAK1-related kinase activating pseudokinase 1 (NACK) is a critical co-activator of Notch signaling and binds to the Notch1 ternary complex. Herein we report that p300 and CBP acetylate mastermind-like transcriptional coactivator 1 (Maml1) on amino acid residues K188 and K189 to recruit NACK to the Notch1 ternary complex, which results in the recruitment of RNA polymerase II to initiate transcription...

BACKGROUD: Laryngeal preservation is an important consideration when treating cervical esophageal cancers (CECs) such as laryngeal cancer. The standard treatment for CEC allowing laryngeal preservation is chemoradiotherapy. However, in cases of laryngeal cancer, chemoselection has also been applied as a treatment strategy that promotes larynx preservation. This strategy involves assigning the appropriate radical treatment according to the primary tumor's response to induction chemotherapy...

Esophageal squamous cell carcinoma (ESCC) in humans is a deadly disease associated with dietary zinc (Zn)-deficiency. In the rat esophagus, Zn-deficiency induces cell proliferation, alters mRNA and microRNA gene expression, and promotes ESCC. We investigated whether Zn-deficiency alters cell metabolism by evaluating metabolomic profiles of esophageal epithelia from Zn-deficient and replenished rats vs sufficient rats, using untargeted gas chromatography time-of-flight mass spectrometry (n = 8/group). The Zn-deficient proliferative esophagus exhibits a distinct metabolic profile with glucose down 153-fold and lactic acid up 1...

In the past decades, the oncogenic role of fibroblast growth factor receptor 2 has been demonstrated in a number of cancer types. However, studies have reported contradictory findings concerning the correlation between fibroblast growth factor receptor 2 expression and prognosis in solid tumors. To address this discrepancy, we performed a meta-analysis with 18 published studies (2975 patients) retrieved from PubMed, EMBASE, and Web of science. Data were extracted and computed into odds ratios. The results showed that fibroblast growth factor receptor 2 overexpression was significantly associated with decreased 3-year overall survival (odds ratio = 1...

Esophageal squamous cell carcinoma is the sixth most common cancer in the developing world. The aggressive nature of esophageal squamous cell carcinoma, its tendency for relapse, and the poor survival prospects of patients diagnosed at advanced stages, represent a pressing need for the development of new therapies for this disease. Chronic inflammation is known to have a causal link to cancer pre-disposition. Nuclear factor kappa B and signal transducer and activator of transcription 3 are transcription factors which regulate immunity and inflammation and are emerging as key regulators of tumor initiation, progression, and metastasis...

Laparoscopic radical gastrectomy with lymph node dissection has widely penetrated to East Asian countries, where incidence of gastric cancer occurrence is higher than the rest of the world. Laparoscopic distal gastrectomy for cStageI disease is regarded as one of the option in daily practice in the latest Japanese guidelines; however its applicability to more advanced disease (Stage II/III) is still under debate. Actually, operative techniques of laparoscopic D2 dissection is being matured, but still, necessity of total omentectomy, splenic hilar dissection, management of bulky nodes or large primary tumor, high-level anastomosis in esophageal invasion cases, and extensive peritoneal lavage can be raised as technical limitations...

REVIEW
Hiroyuki Odagiri, Hideo Yasunaga
Endoscopic submucosal dissection (ESD) is a relatively new procedure used for the treatment of early gastrointestinal cancers regardless of the lesion size and configuration, and it has gradually acquired popularity because of its minimally invasive nature. As compared to conventional endoscopic resection, ESD is a more complex procedure and requires a higher level of technical skill. Therefore, it is associated with a higher complication rate. Many previous studies that investigated the complication rates following ESD analyzed data from a limited number of specialized centers, possibly leading to an underestimation of the complication rates...
