Background: ESD allows higher rates of en-bloc and R0 resections, but has occasionally complications such as aspiration pneumonia. Factors associated with aspiration pneumonia are not completely understood.

Aims: To analyze the relationship between aspiration pneumonia and preoperative factors including pulmonary function tests.

Following the publication of this article, we realize that there were some errors in the manuscript. Details of the experiments describing the gene silencing of RUNX3 with small interfering RNA (siRNA) were erroneously included in this paper, and all references to siRNA should have been deleted from the manuscript prior to publication. In the subsection entitled 'Cell lines and cell culture' on page 2577, the left‑hand column, the text should have indicated that the human HCC cell lines Hep3B and Huh7 were obtained from the American Type Culture Collection (ATCC; Manassas, VA, USA), whereas HLF cells were obtained from the Japanese Cancer Resources Bank (Tokyo, Japan).

Runt-related transcription factor 3 (RUNX3) is known to function as a tumor suppressor in gastric cancer and other types of cancers, including hepatocellular carcinoma (HCC). However, its role has not been fully elucidated. In the present study, we aimed to evaluate the role of RUNX3 in HCC.

Background And Aim: Reduced expression in immortalized cells/dickkopf-3 (REIC/DKK3) is a reported tumor suppressor gene and has potential to become an innovative therapy for various cancers. We examined the antitumor immunological effects of human REIC/DKK3 protein against pancreatic cancer.

Methods: Activation of extracellular signal-regulated kinases 1 and 2, mammalian target of rapamycin, and signal transducer and activator of transcription 3 by REIC/DKK3 protein was assessed in human peripheral blood mononuclear cells using immunoblotting.

Microenvironment plays an important role in epithelial-mesenchymal transition (EMT) and stemness of cells in hepatocellular carcinoma (HCC). Epithelial cell adhesion molecule (EpCAM) is known as a tumor stemness marker of HCC. To investigate the relationship between microenvironment and stemness, we performed an in vitro co-culture assay.

Background And Aim: The reduced expression in immortalized cells REIC/the dickkopf 3 (Dkk-3) gene, tumor suppressor gene, is downregulated in various malignant tumors. In a prostate cancer study, an adenovirus vector carrying the REIC/Dkk-3 gene (Ad-REIC) induces apoptosis. In the current study, we examined the effects of REIC/Dkk-3 gene therapy in pancreatic cancer.

Loss or decreased expression of runt-related transcription factor 3 (RUNX3), a tumor suppressor gene involved in gastric and other cancers, has been frequently observed in hepatocellular carcinoma (HCC). The objective of this study was to identify the regulatory mechanism of the epithelial-mesenchymal transition (EMT) by RUNX3 in HCC. Human HCC cell lines, Hep3B, Huh7, HLF and SK-Hep1, were divided into low- and high-EMT lines, based on their expression of TWIST1 and SNAI2, and were used in this in vitro study.

Runt-related transcription factor 3 (RUNX3) is a candidate tumor suppressor gene that is downregulated in various cancers. In the present study, we analyzed the regulatory function of RUNX3 on Jagged-1 (JAG1) expression and cancer stem cell (CSC) signaling in hepatocellular carcinoma (HCC). Eleven HCC cell lines and 30 human HCC tissues were used.

von Hippel-Lindau (VHL) syndrome is an inherited neoplastic syndrome caused by abnormity of the VHL gene found on the short arm of the chromosome 3. We reported a case of VHL disease diagnosed by the detection of multiple pancreatic endocrine tumors and renal tumor 13 years after bilateral adrenalectomy. A 40-year-old man presented with multiple pancreas tumors (maximum size 42 mm in diameter) detected by screening abdominal ultrasonography.

Article Synopsis
  • A 28-year-old man presented with tarry stools, leading to examinations that revealed a bleeding submucosal tumor at the papilla of Vater and a swollen # 17b lymph node, suggesting hypervascularity.
  • The tumor was diagnosed as gangliocytic paraganglioma, which showed metastasis to the affected lymph node after enucleation.
  • While most gangliocytic paragangliomas are benign, this case highlights that about 7% can spread to lymph nodes, emphasizing its significance for treatment strategies.

The clinical efficacy and safety of irinotecan plus infusional fluorouracil/l-leucovorin (FOLFIRI) in patients with fluoropyrimidine-resistant metastatic colorectal cancer were studied retrospectively. 20 patients were treated with FOLFIRI at our hospital between October 2003 and November 2005. The objective overall response rate was 28% (5/18; 95% confidence interval, 9.

Endoscopic examination of a 39-year-old woman revealed a flat-elevated submucosal tumor (SMT) in the upper third area of the stomach and a IIc lesion in the anterior wall of the lower third of the stomach. Endoscopic ultrasonography findings suggested an aberrant pancreas. Both lesions were resected by distal gastrectomy.
