Concentrations of polyamines in renal cell carcinoma

In order to obtain biochemical indicators for histopathological, biological and clinical malignancy of renal cell carcinoma (RCC), concentrations of protein, RNA, DNA and polyamines in 14 samples of RCC were measured and examined on their histopathological properties and clinical malignancies. The concentration of spermidine in RCC was significantly higher than that in normal renal tissue and a statistically significant difference was not detected between the concentrations of the other compounds in RCC and normal tissue. The concentration of spermidine and the ratio of spermidine/spermine were found to increase in the order of normal tissue, the well-differentiated type and the poorly-differentiated type of RCC while no significant difference was detected between the concentrations of the other compounds in these types. There was no difference in the concentrations of the compounds examined among the non-metastasis and istant-metastasis groups of RCC.
