In this study, we compared the c-erb B-2/neu gene amplification and expression of tissue specimens obtained from the bladders of normal controls and patients with high-grade transitional cell bladder carcinoma.

Alterations in the expression of p53, c-erbB-1 and c-erbB-2 were found frequently in human transitional cell carcinoma of the urinary bladder and may be of clinical use in defining patient sub-groups of differing prognosis.

Using a polymerase chain reaction (PCR)-based method, we examined the frequency of the homozygous deleted genotype (GSTM1 0/0) in 229 patients with transitional cell carcinoma of the bladder and 211 control subjects who were enrolled from the Urology Clinics at Duke University Medical Center and the University of North Carolina Hospitals.
Histologic specimens of transitional-cell carcinoma of the bladder (stages Pa, noninvasive disease, to P4, disease with direct extension into adjacent organs or structures) from 243 patients who were treated by radical cystectomy were examined for the immunohistochemical detection of p53 protein.
To investigate the overexpression of p53 oncoprotein in transitional-cell carcinoma of the bladder, 58 bladder cancer specimens of different clinical stages and histological grades were investigated using an immunohistochemical approach.
Our aim was to investigate the expression of p53 oncoprotein in superficial and invasive transitional cell bladder cancer (TCC) as well as its correlation with established prognostic factors, such as histologic grade, tumor stage, DNA content, and survival.
Relationship of genetic instability with immunoreactivities for p53 protein and proliferating cell nuclear antigen in transitional cell carcinoma of the bladder.
In immunohistochemical studies of bladder tumor tissue, over expression of p53 protein was detected with antibody pAb1801 and loss of Rb protein expression was evaluated with antibody PMG3-245 in patients with transitional cell carcinoma of the bladder.
