In spite of the undisputed importance of altered expression patterns of microRNAs (miRNAs) in various cancers, there is little information on the clinicopathologic significance of cancer-related miRNAs (MIR21, MIR143, MIR144, MIR145, and MIR205) in esophageal squamous cell carcinoma (ESCC). We examined the expression levels of the precursor and mature miRNA(More)
Biliary tract cancer (BTC) is often difficult to diagnose definitively, even through histological examination. MicroRNAs (miRNAs) regulate a variety of physiological processes. In recent years, it has been suggested that profiles for circulating miRNAs, as well as those for tissue miRNAs, have the potential to be used as diagnostic biomarkers for cancer.(More)
Prognostic tests for patients with early-stage lung cancer may provide needed guidance on postoperative surveillance and therapeutic decisions. We used a novel strategy to develop and validate a prognostic classifier for early-stage lung cancer. Specifically, we focused on 42 genes with roles in lung cancer or cancer prognosis. Expression of these(More)
Intussusception in adults represents only 5% of all cases and is usually caused by a small bowel lesion acting as the apex of the intussusception. We report an unusual case of intussusception in man caused by a lipomatous lesion located in the ileum acting as the lead point. After repeated admissions to our hospital for ileus, the possibility of(More)
The genomic region containing PIK3CA was found to be amplified in esophageal squamous cell carcinoma (ESCC) tissue. PIK3CA at 3q26, which encodes the p110alpha catalytic subunit of phosphatidylinositol (PI) 3-kinase, is a unique intracellular signal transducer characterized by its lipid substrate specificity. In order to characterize PIK3CA in ESCC, we(More)
The carcinosarcoma of the esophagus is a rare malignant neoplasm consisting of both carcinomatous and sarcomatous components. A case of so-called carcinosarcoma of the esophagus is described herein. A 69-year-old man presented with dysphagia and was admitted to our hospital. Imaging studies revealed a localized ulcerative tumor in the middle intrathoracic(More)
It is now evident that changes in microRNA are involved in cancer progression, but the mechanisms of transcriptional regulation of miRNAs remain unknown. Ski-related novel gene (SnoN/SKIL), a transcription co-factor, acts as a potential key regulator within a complex network of p53 transcriptional repressors. SnoN has pro- and anti-oncogenic functions in(More)
BACKGROUND Earlier studies have identified the minimal overlapping region of amplification at 3q26 in esophageal squamous cell carcinoma (ESCC) by comparative genomic hybridization (CGH) analysis. These include PIK3CA which encodes the p110alpha catalytic subunit of phosphatidylinositol (PI) 3-kinase, a telomerase RNA component (TERC), a squamous cell(More)
BACKGROUND Hepatic pedicle clamping (HPC) has been demonstrated to be effective for short-term outcomes during hepatic resection. However, HPC-induced hepatic ischemia/reperfusion injury can accelerate the outgrowth of hepatic micrometastases in experimental studies. The conclusive evidence regarding effects of HPC on long-term patient outcomes after(More)
