Abstract:
We studied the association between epidermal growth factor (EGF) binding capacity and histopathologic features or prognosis in human renal cell carcinoma (RCC) by Scatchard analysis in 67 patients. EGF binding capacity was significantly greater in metastatic than in nonmetastatic tumors, and in nuclear grade 3 than nuclear grade 1 tumors. Multivariate analysis revealed that tumor stage, nuclear grade, EGF binding capacity, and tumor size significantly correlated with overall survival. These results suggest that EGF binding may be an important determinant of prognosis in patients with RCC.
