BACKGROUND Five randomized trials of adjuvant trastuzumab have reported significant improvements in recurrence-free survival (RFS) and overall survival. However, patients with node-negative tumors 1 cm or smaller were excluded from these trials. We assessed the recurrence risk and benefit of adjuvant therapy in such patients with small tumors. METHODS We(More)
Several recent studies have reported that selectins are produced during ischemia-reperfusion injury, and that selectin ligands play an important role in cell binding to the endothelium and in liver metastasis. Portal clamping during pancreaticoduodenectomy with vessel resection for pancreatic head cancer causes(More)
Pancreatic schwannoma is a very rare tumor that tends to be confused with other pancreatic tumors preoperatively. We report a case of schwannoma of the pancreatic head. A 40-year-old woman was admitted to our hospital for treatment of a pancreatic tumor which was found by medical checkup. It was a well-defined solid tumor exhibiting heterogeneous(More)
The mechanisms by which apoptotic myocytes are removed by macrophages have not been fully elucidated. This study examined whether apoptotic myocytes actively recruit macrophages by generating monocyte chemoattractant protein-1 (MCP-1) in experiments in vitro and in vivo. Neonatal rat cardiac myocytes were incubated for 4 h in the presence or absence of(More)
Gastro-duodenal content reflux from gastro-esophageal reflux disease (GERD) induces the inflammation-metaplasia-dysplasia-adenocarcinoma sequence. Proton pump inhibitors (PPIs) are potent blockers of gastric acid secretion, which are widely used for treating GERD and peptic ulcer-associated acid-secreting diseases. The effect of PPI therapy on esophageal(More)
BACKGROUND The prognosis of gastric cancer with para-aortic lymph node (PAN) metastasis is poor. We applied triple combination chemotherapy with docetaxel, cisplatin, and S-1 (DCS therapy) as pre-operative chemotherapy and investigated the outcome of the combination of this therapy and gastrectomy with para-aortic lymph node dissection (PAND). METHODS We(More)
BACKGROUND Radical antegrade modular pancreatosplenectomy (RAMPS) has theoretical advantages for curative resection of adenocarcinomas of the left pancreas. The anterior renal fascia is a key structure, and resection planes should run posterior to this fascia. However, it is difficult to delineate this fascia and set a precise dissection plane. We modified(More)
BACKGROUND Carbon dioxide-rich water bathing has the effect of vasodilatation, whereas it remains undetermined whether this therapy exerts an angiogenic action associated with new vessel formation. METHODS AND RESULTS Unilateral hindlimb ischemia was induced by resecting the femoral arteries of C57BL/J mice. Lower limbs were immersed in CO2-enriched water(More)
We previously reported that hepatic stellate cells (HSCs) activated by angiotensin II (AngII) facilitate stromal fibrosis and tumor progression in intrahepatic cholangiocarcinoma (ICC). AngII has been known as a growth factor which can promote epithelial-to-mesenchymal transition (EMT) in renal epithelial cells, alveolar epithelial cells and peritoneal(More)
Animal models are important for the development of novel therapies for esophageal cancer. Histone deacetylase 1 (HDAC1)/metastasis-associated gene (MTA1) complexes inhibit p53 acetylation and thus, inhibit p53-induced apop-tosis. The aim of the present study was to evaluate HDAC1 and MTA1 expression in esophageal carcinogenesis in rats. The rats underwent a(More)
