Soluble factors in the tumor microenvironment may influence the process of angiogenesis; a process essential for the growth and progression of malignant tumors. In this study, we describe a novel antiangiogenic effect of conditional replication-selective adenovirus through the stimulation of host immune reaction. An attenuated adenovirus (OBP-301,(More)
Replication-competent oncolytic viruses are being developed for human cancer therapy. We previously reported that an attenuated adenovirus OBP-301 (Telomelysin), in which the human telomerase reverse transcriptase promoter element drives expression of E1A and E1B genes linked with an internal ribosome entry site, could replicate in and causes selective(More)
Oncolytic adenoviruses are being developed as novel anticancer therapeutics and currently undergoing clinical trials. We previously demonstrated that telomerase-specific replication-competent adenovirus (Telomelysin: OBP-301), in which the human telomerase reverse transcriptase (hTERT) promoter regulates viral replication, efficiently killed human tumor(More)
BACKGROUND/PURPOSE The cholecystic veins are thought to be an important metastatic route of gallbladder carcinoma to the liver. In the present study we evaluated the cholecystic venous drainage area, utilizing a novel method, indocyanine green (ICG) fluorescence angiography after superselective catheterization of the cholecystic artery, to detect and(More)
Oxaliplatin-based chemotherapy is widely used for advanced colorectal cancer treatment, but it occasionally induces liver injury that is characterized histologically by sinusoidal dilatation, hepatic plate atrophy and/or venular obstruction. Most of the patients do not reveal apparent radiological abnormalities, however. Here, we report the case of a(More)
PURPOSE Dendritic cells are the most potent antigen-presenting cells for initiating cellular immune responses. Dendritic cells are attractive immunoregulatory cells for cancer immunotherapy, and their efficacy has been investigated in clinical trials. The tumor suppressor gene p53 is pivotal in the regulation of apoptosis, and p53-based immunization is an(More)
A 73-year-old man was followed up for HCV-associated chronic hepatitis and hepatocellular carcinoma (HCC), developed in segment 8 of the liver. Radiofrequency ablation (P-RFA) was used to treat the tumor in June 2004. Afterwards, the patient underwent repetitive transcatheter arterial chemoembolization (TACE) against recurrent tumors 5 times. An abdominal(More)
5-FU is among the drugs most frequently used in the treatment of gastrointestinal malignancies. Also, it has been reported to reveal severe side effects in the case of a dihydropyrimidine dehydrogenase (DPD) deficiency. A 75-year-old man showed severe nausea and vomiting after administration of UFT/Uzel as adjuvant chemotherapy. Because of severe(More)
Systemic treatment for metastatic or advanced colorectal cancer(mCRC)has remarkably progressed during recent years. All previously untreated mCRC patients at our institution between November, 2007 and June, 2010 were retrospectively evaluated. Of 72 patients, 39 were treated with chemotherapy alone, and 33 were treated with chemotherapy plus(More)
We reported a case of DIC who was administered FEC90 (5-FU 1,000 mg/body, epirubicin 170 mg/body, cyclophosphamide 1,000 mg/body) for advanced breast cancer. A 55-year-old woman was referred to our hospital with lumbago. There was a huge tumor in her left breast (10x10 cm) and bone scintigraphy showed multiple bone metastasis, so she was treated with FEC90.(More)
