    abstract = "Aim: The aim of this study was to determine the potential synchronous
contribution of alterations in TGF-beta RII, BAX, IGFIIR, caspase-5,
hMSH3 and hMSH6 genes to the development and clinical outcome of bladder
cancer, in relation to p53 mutations, microsatellite status and
hMLH1/hMSH2 expression.
Methods: Molecular biology techniques as well as immunohistochemistry
were applied in 69 samples from patients with urothelial carcinoma.
Results: Microsatellite alterations were observed in TGF-beta RII(A)(10)
(16%) and BAX(G)(8) (3%), irrespective of the presence of p53
mutations, but not in IGFIIR(G)(8), caspase-5(A)(10), hMSH3(A)(8) and
hMSH6(C)(8). A statistically significant correlation could be found only
between hMLH1 expression and the presence of microsatellite instability
(Fisher’s exact test, p=0,013). Survival analysis indicated that apart
from grade and T-category, hMLH1 expression was the only parameter
significantly affecting overall survival (p=0.021 in univariate and
p=0.015 in multivariate analysis) and recurrence-free survival (p=0.0463
in univariate and p=0.022 in multivariate analysis).
Conclusions: We conclude that alterations of the examined target genes
of MSI are rare in urinary bladder carcinoma and they are not associated
with microsatellite instability or the presence of p53 mutations."
