The role of T helper type 1 (Th1) and Th2 cells in tumor immunity was investigated using Th cells induced from ovalbumin (OVA)-specific T cell receptor transgenic mice. Although Th1 cells exhibited stronger cytotoxicity than Th2 cells, both cell types completely eradicated tumors when transferred into mice bearing A20 tumor cells transfected with the OVA(More)
In 2009, the rate of thoracoscopic esophagectomy for esophageal cancer was about 20 % in Japan. This low rate may be due to the difficulty in maintaining a good surgical field and the meticulous procedures that are required. The purpose of this study was to establish and evaluate a new procedure for performing a thoracoscopic esophagectomy while the patient(More)
 To investigate the precise role of antigen-specific Th1 and Th2 cells in tumor immunity, we developed a novel adoptive tumor-immunotherapy model using OVA-specific Th1 and Th2 cells and an OVA gene-transfected tumor. This therapeutic model demonstrated that both antigen-specific Th1 and Th2 cells had strong antitumor activity in vivo with distinct(More)
Background: Hepatic hydrothorax is defined as a pleural effusion that arises in patients with cirrhosis of the liver and no cardiopulmonary disease; it is believed to result from peritoneopleural communication through a defect in the diaphragm. Methods: Nine patients underwent thoracoscopic pleurodesis. The diaphragmatic defect was detected and corrected in(More)
The combined therapeutic effect of natural killer T (NKT) cell ligand α-galactosylceramide (α-GalCer) and IL-12 against highly metastatic B16-BL6-HM melanoma cells was investigated. In comparison with a single administration of α-GalCer or IL-12, the combined treatment of tumor-bearing mice with α-GalCer plus IL-12 caused a super-induction of serum IFN-γ(More)
Partial response (PR) was obtained in a patient with advanced colon cancer following peptide vaccine therapy. A 61-year-old woman was referred to our hospital for peptide vaccine therapy. She had undergone sigmoidectomy at a nearby hospital and eventually developed multiple metastases to the lung and pelvic lymph nodes with left hydronephrosis. A ureteral(More)
Endoscopic submucosal dissection (ESD) recently has been aggressively performed to treat superficial esophageal cancer; however, it is difficult to secure a good field of view for mucosal dissection, and the technique requires considerable skill. We have developed a double-channel ESD method using an endoscopic esophageal mucosal resection (EEMR) tube that(More)
The indications for endoscopic resection (ER) in esophageal cancer are limited to cases without lymph node metastasis because it is a local therapy. The relationship between cancer depth and lymph node metastasis has been clarified according to the pathologic analysis of lymph nodes removed during esophagectomy for early esophageal cancer. Cancer invasion(More)
During the last 30 years, the median survival time and 5-year survival rate of esophageal cancer have improved significantly. In recent years, two major factors have greatly contributed to improve the outcomes of treatment for esophageal cancer in Japan. One is the establishment of endoscopic diagnosis and treatment of superficial esophageal cancer, and(More)
