    Abstract:
    The members of the IAP (inhibitors of apoptosis) family, which includes survivin, have recently emerged as modulators of an evolutionarily conserved step in apoptosis. Survivin is present during embryonic and fetal development, but it is downregulated in normal adult tissues. However, it becomes re-expressed in a variety of cancers. We investigated the prognostic importance of the expression of survivin in transitional cell carcinoma of the upper urinary tract (TCC-UUT). In 126 cases of TCC-UUT, we examined its expression (using immunohistochemistry), and also its relationship with the expressions of bcl-2 oncoprotein, p53 oncoprotein, and proliferating cell nuclear antigen (PCNA) immunoreactivity, clinicopathologic parameters, and clinical outcome. A positive expression of survivin was recognized in 12.7% of samples, a granular pattern being apparent within the cytoplasm of tumor cells. Survivin expression did not correlate with clinicopathologic findings, bcl-2 oncoprotein expression, p53 oncoprotein expression, PCNA index, or prognosis. In the normal urothelium, its expression was not detected. In conclusion, the expression of survivin does not predict prognosis in TCC-UUT.
