To evaluate the grade of heterogeneicity of nuclear DNA- content and intratumoural expression of p53 and bcl2 expression in human renal cell carcinoma (RCC), nuclear DNA- content, p53 and bcl-2 proteins expression in 296 samples of renal cell carcinoma were related to survival in 32 operable patients. The expression of p53 and bcl-2 proteins was studied by immunochemistry, and DNA content by flow cytometry. Mean follow up was 26.25 months (SD 12.08, range 1-43). Heterogeneous DNA content was detected in 21/32 (65.6%) tumours and correlated with more advanced Robson stage (p=0.04) and, nearly significant, larger tumour size (p=0.06). Intratumour heterogeneity was also detected for p53 and bcl-2 protein overexpression. A high level of p53 expressions correlated with low levels of bcl-2 gene product (p=0.008), aneuploidy (p
