PURPOSE This study aimed to identify novel hypoxia-inducible and prognostic markers in vivo from hypoxic tumor cells. EXPERIMENTAL DESIGN Using carbonic anhydrase 9 and CD34 as a guide for hypoxic tumor cells, laser capture microdissection was used to isolate colorectal cancer (CRC) liver metastases. The samples were analyzed by microarray analysis, in(More)
BACKGROUND AND OBJECTIVES Adhesion molecules are implicated in the progression of colorectal cancer (CRC). Despite the evidence of association between their expression and patients' prognosis, the data have not been examined simultaneously in a same study; thus, the relative clinical value remained largely unknown. The aim of this study was to identify the(More)
Angiogenesis is a compensatory mechanism that enables malignant tumors to survive in an oxygen-deficient environment. To test our hypothesis that hypoxia stimulates the production of angiopoietin-2 (Ang-2) in colorectal cancer (CRC), we investigated the expression of Ang-2 in three cultured CRC cell lines, and in specimens from 11 CRC metastatic liver(More)
We here report a 43-year-old male patient with minute liver metastases from a rectal carcinoid. Hepatic nodules were diagnosed during surgery, although they were not diagnosed by preoperative computed tomography or ultrasound examination. The rectal carcinoid was resected together with liver metastases and the patient has had no disease recurrence for 5(More)

Esophageal endoscopic submucosal dissection (ESD) is technically difficult. To make it safer, we developed a novel method using overtube with a traction forceps (OTF) for countertraction during submucosal dissection. We conducted an ex vivo animal study and compared the clinical outcomes between OTF-ESD and conventional method (C-ESD). A total of 32(More)
