BACKGROUND A minilaparotomy approach is technically feasible for the resection of colorectal cancer in select patients. The aim of this study was to clarify the risk factors preventing the success of a minilaparotomy in the resection of colorectal cancer. METHODS Between April 2005 and August 2008, 141 consecutive patients were enrolled in this(More)
The metastasis suppressor gene nm23 located on chromosome 17 might be one of the targets in deletions of chromosome 17. In this study, we analyzed the expression of nm23 and chromosome 17 aberrations in gastric cancer and assessed their clinicopathological and prognostic significance. In 103 gastric cancer patients, we examined nm23 expression by(More)
We investigated the correlation between the frequency of numerical aberrations of chromosome 17 and clinicopathological features of gastric cancer. The copy number of chromosome 17 was examined with fluorescence in-situ hybridization (FISH) in frozen specimens from 100 primary gastric cancers. Chromosomal numerical aberrations were diagnosed as chromosomal(More)
The CD4+CD25High T-cell phenotype has an essential immunoregulatory role, while the CD4+CD28null T-cell reflects immune pathology. We investigated the profiles of the CD4+CD25High and the CD4+CD28null T-cell phenotypes in patients with ulcerative colitis (UC) during active and quiescent phases as well as following colectomy. Fifty-nine UC patients, 34(More)
We present a female patient with continuous melena, diagnosed with rectal variceal bleeding. She had a history of esophageal varices, which were treated with endoscopic therapy. Five years after the treatment of esophageal varices, continuous melena occurred. Since colonoscopy showed that the melena was caused by giant rectal varices, we thought that they(More)
Background: Aberrations in chromosome 17 are important in carcinogenesis. We recently reported that numerical aberrations in chromosome 17 were associated with tumor progression in gastric cancer. The aim of this study was to determine the biological characteristics of gastric tumor cells with chromosome 17 numerical aberrations. Methods: Gastric tumor(More)
Extracorporeal granulocyte and monocyte/macrophage adsorption (GMA) using an adacolumn filled with cellulose acetate beads as GMA carriers selectively depletes excess and activated myeloid leucocytes from the circulation and has been used as a non-pharmacologic adjunct therapy in patients with inflammatory bowel disease (IBD). In this study we applied(More)
