Regulation by hypoxia may underlie the expression of vascular endothelial growth factor in bladder cancer. We have compared the distribution of vascular endothelial growth factor mRNA with a hypoxia marker, carbonic anhydrase 9 (CA IX). vascular endothelial growth factor mRNA was analysed by in situ hybridisation and CA IX by immunochemistry in 22 cases of(More)
Renal cell carcinoma (RCC) is an angiogenic tumor resistant to standard cytotoxic chemotherapeutic agents. Although often responsive to immunomodulatory agents including interleukin 2 and IFN-alpha, the overall results in randomized Phase III studies are disappointing with only modest improvements in overall survival. This Phase II study evaluated the(More)
Vascular endothelial growth factor (VEGF) is an important factor mediating tumour angiogenesis. VEGF mRNA is differentially expressed in bladder cancer with high expression in superficial tumours (stage pTa and pT1) contrasting with low expression in muscle invasive tumours (stage > or = pT2). To investigate mechanisms regulating VEGF expression in bladder(More)
Tumor development is angiogenesis dependent, and vascular endothe 11*1 growth factor (VEGF) is a key growth factor in this process. We demonstrate that high expression of VEGF mRNA in 55 superficIal blad der cancers was associated with earlier recurrence (P = 0.001; hazard ratio, 3.09) and progression to a more invasive phenotype (P = 0.02; hazard ratio,(More)
Suramin is an antitrypanosomal agent with antineoplastic activity, but with serious systemic side effects. We administered Suramin intravesically to determine a concentration with low toxicity but with evidence of a pharmacodynamic effect, to recommend a dose level for phase II trials. This was an open-labelled, non-randomized dose-escalation phase I study.(More)
Aberrant Wnt gene expression is involved in the development of breast cancer, but its role in other tumours is unknown. Wnts regulate cadherin function, previously shown to be more commonly deregulated in invasive bladder cancer. This study investigated whether factors upstream of cadherins were aberrantly expressed in superficial bladder cancer. The(More)
BACKGROUND Germline mutations within DNA-repair genes are implicated in susceptibility to multiple forms of cancer. For prostate cancer (PrCa), rare mutations in BRCA2 and BRCA1 give rise to moderately elevated risk, whereas two of B100 common, low-penetrance PrCa susceptibility variants identified so far by genome-wide association studies implicate RAD51B(More)
