Prognostic parameters of renal cell carcinoma. Clinicopathologic and DNA image cytometric analysis in 133 pT3a cases.
In 133 cases of patients with renal cell carcinoma which infiltrated locally into the renal fatty tissue (stage pT3a, TNM classification of 1987), the prognostic potential of the following parameters was investigated: symptoms, patient's age at the time of operation, tumor size and localization, grade of malignancy, cell type, growth pattern, and prognostic score according to Störkel et al. [Eur Urol 1990;18(suppl 2):36]. Additionally, automated image analysis DNA cytometry was performed on 110/133 carcinomas. After an average observation period of 3.6 years (maximum 10.1 years), 59 (44.4%) of the patients died of their tumors. The cause-specific 5- and 10-year survival rates were 51.3 and 29.1%, respectively. Statistically significant differences (p < 0.05) within the individual parameters were found only for the grade of malignancy and the corresponding prognostic score. Using DNA cytometry, 13 types of renal cell carcinoma were differentiated; 90% of the tumors contained aneuploid cells. Significant differences between these relative to prognosis did not exist. In the case of locally advanced renal cell carcinoma, the DNA histogram does not seem to be superior to conventional prognostic criteria.
