BACKGROUND Postsurgical recurrence of hepatocellular carcinoma (HCC) is frequent and fatal. Adoptive immunotherapy is active against HCC. We assessed whether postoperative immunotherapy could lower the frequency of recurrence. METHODS Between 1992 and 1995, we did a randomised trial in which 150 patients who had undergone curative resection for HCC were(More)
The presence of mRNAs for vascular endothelial growth factor (VEGF) and a VEGF-related protein, placenta growth factor (PIGF) was examined in 29 cases of renal cell carcinoma tissues and adjacent normal kidney tissues and in 4 human renal cell carcinoma cell lines. Northern blot analysis showed that 26 of 27 hypervascular renal cell carcinoma tissues (96%)(More)
Cultivation of T lymphocytes with immobilized anti-CD3 monoclonal antibody and human recombinant interleukin-2 induced a rapid proliferative response. This procedure was applied to expansion culture of peripheral blood lymphocytes obtained from cancer patients for use in adoptive immunotherapy. Peripheral blood mononuclear cells were separated from 20 ml of(More)
Renal clear cell carcinoma (RCCC) is a malignant tumor with poor prognosis caused by the high incidence of metastasis to distal organs. Although metastatic RCCC cells frequently show aberrant cytoskeletal organization, the underlying mechanism has not been elucidated. DAL-1/4.1B is an actin-binding protein implicated in the cytoskeleton-associated(More)
Paclitaxel (PTX) is one of the most effective anticancer agents. In clinical practice, however, high incidences of adverse reactions of the drug, for example, neurotoxicity, myelosuppression, and allergic reactions, have been reported. NK105, a micellar nanoparticle formulation, was developed to overcome these problems and to enhance the antitumour activity(More)
We conducted a population-based, double-blind, randomized controlled trial to examine the effect of vitamin C supplementation on serum pepsinogen (PG) level, Helicobacter pylori (H. pylori ) infection, and cytotoxin-associated gene A (Cag A) status. Subjects aged 40 to 69 years living in one village in Akita prefecture, a high-risk area for gastric cancer(More)
Structural alterations of the p53 gene were investigated to elucidate the molecular biological difference between superficial and invasive bladder cancer by polymerase chain reaction single-strand conformation polymorphism analysis. In 25 bladder cancers obtained from 23 patients, p53 gene mutations were investigated in exon regions 4 to 11. Twenty-four(More)
In spite of the clinical usefulness of cisplatin (CDDP), there are many occasions in which it is difficult to continue the administration of CDDP due to its nephrotoxicity and neurotoxicity. We examined the incorporation of CDDP into polymeric micelles to see if this allowed the resolution of these disadvantages. Cisplatin was incorporated into polymeric(More)
PURPOSE We elucidated the role of methylation in the promoter region of the 1 gene in bladder carcinogenesis, particularly in those comprising carcinoma in situ. MATERIALS AND METHODS A total of 49 cases of transitional cell carcinoma of the bladder obtained from transurethral resection were examined. Methylation status of the 1 promoter region was(More)
BACKGROUND The treatment of early gastric cancer (EGC) by endoscopic submucosal dissection (ESD) has been rapidly gaining popularity in Japan. However, the procedure needs a high quality of skill. To facilitate complicated ESD by using a single working-channel gastroscope ("one-hand surgery method"), the magnetic-anchor-guided ESD (MAG-ESD) controlled by an(More)
