The Expression of Caspase 3 and p21 in Renal Cell Carcinoma / 대한비뇨기과학회지

ABSTRACT

PURPOSE: The objective of this study was to evaluate the Caspase 3 and p21 expression level and to understand the correlation between Caspase 3 expression and the clinical factors in renal cell carcinoma. MATERIALS AND METHODS: Forty-two patients with renal cell carcinoma were enrolled in this study. Immunohistochemical staining of Caspase 3 and p21 was performed in formalin-fixed and paraffin-embedded tissue sections using rabbit polyclonal antibody (Caspase 3) and mouse antibody (p21). The Caspase 3 and p21 expression levels were compared with the TNM stage, Fuhrman grade, pathological type and survival rates. RESULTS: The Caspase 3 expression level correlated only with the Fuhrman grade (p=0.017). There was no significant correlation between the Caspase 3 and p21 expression level. The prognostic values did not correlate with the Caspase 3 and p21 expression level. CONCLUSIONS: The prognostic value of the Caspase 3 expression level in renal cell carcinoma was insufficient. The relationship between Caspase 3 and p21 was not proven in renal cell carcinoma, and new factors may be implicated with Caspase 3.
