PURPOSE We reported previously that angiogenesis evaluated by intratumor microvessel density (MVD), expression of such angiogenic factors as vascular endothelial cell growth factor (VEGF) and basic fibroblast growth factor (bFGF), and the matrix metalloproteinase-9:E-cadherin ratio (M:E ratio) could identify patients with advanced transitional cell(More)
BACKGROUND To identify organ-specific, metastasis-related factors that can be used to predict the development and location of metastasis of clear cell renal cell carcinoma (CRCC), the authors assessed the angiogenesis and the expression of angiogenesis-related genes in primary and metastatic tumors. METHODS They evaluated intratumoral microvessel density(More)
We demonstrated recently that chronic frequent administration of an adequate biological dose of the angiogenesis inhibitor TNP-470 (AGM-1470, O-chloracetyl-carbamoyl fumagillol) completely inhibits spontaneous lymph node metastasis but does not have a complete response on tumor growth of nonestablished or established human metastatic transitional cell(More)
BACKGROUND We report a case of a 33-year-old man who presented with immunoglobulin (Ig)G4-related disease (IgG4-RD) forming a pseudotumor in the left paratesticular region during oral administration of corticosteroid for Wells syndrome, which involves cellulitis with eosinophilia. CASE PRESENTATION The patient was introduced to our institution from a(More)
PURPOSE Patients with locally advanced (ie clinically extravesical) transitional cell carcinoma are at high risk for recurrence after cystectomy. Although randomized trials have established an incremental benefit from the addition of chemotherapy in this setting, many patients still have disease relapse, and therefore it is necessary to determine patient(More)
It has been reported that dogs are capable of identifying cancer in humans by detecting a specific odor: bladder cancer by detecting urine odor and other cancers by detecting exhaled breath odor. However, no odor recognized by dogs that indicates cancer has been identified. In this study, we examined whether bladder cancer could be detected by gas(More)
5-aminolevulinic acid (ALA) is a naturally occurring amino acid that is a protoporphyrin IX (PpIX) precursor and a next-generation photosensitive substance. After exogenous administration of ALA, PpIX specifically accumulates in cancer cells owing to the impaired metabolism of ALA to PpIX in mitochondria, which results in a red fluorescence following(More)
PURPOSE The purpose of this study was to clarify the regulatory mechanism of protoporphyrin IX (PpIX) synthesis mediated by 5-aminolevulinic acid (ALA) in human urothelial carcinoma (UC), leading to improved accuracy in photodynamic diagnosis and therapy using ALA. EXPERIMENTAL DESIGN PpIX accumulation in cultured UC cells after incubation for 1-5 h with(More)
We report 7 renal cell carcinomas in 4 patients treated by percutaneous image-guided radiofrequency ablation (RFA). The mean age of the patients was 59 years (male: 2, female: 2). All 4 were imperative cases. Two patients (5 tumor) had hereditary multiple renal cell carcinomas with von Hippel-Lindau (VHL) disease. The other two patients had sporadic renal(More)
PURPOSE Transitional cell carcinoma (TCC) of the urinary tract is a chemosensitive tumor. Most deaths from TCC of the urinary tract are caused by metastasis, which is resistant to conventional chemotherapy. Frequent sites of metastases from TCC of the urinary tract are regional lymph nodes, liver, lung, and bone. Of these distant metastases, bone metastasis(More)
