Summary From 1986 until 1990, in vivo proliferation rates (PRs) in 110 patients with renal-cell carcinoma (RCC) were immunohistochemically determined by the Ki-67 assay. It could be demonstrated that the PRs of RCCs range between only 1% and 15%. Due to its low proliferative kinetics in vivo, tumor cytogenetic investigations of this malignancy remain rare. During short-term in vitro culture, the PRs of this neoplasm increased (21%–82%). Therefore, 36 untreated human RCCs were cultured in vitro for cytogenetic analysis using the G-banding technique. In all, 77.8% (28/36) of the renal malignancies investigated exhibited an aberration of chromosome 3, which seems to serve as a marker for this malignancy. Whereas tumor stage showed no correlation with PR, tumor grade exhibited a strong correlation with this parameter. According to the data presented herein, immunohistochemical determination of the tumor-specific PR using the monoclonal antibody Ki-67 is a practicable, reliable and reproducible method that complements conventional histological tumor grading and staging. This parameter appears to be useful in identifying RCC patients at high risk, especially at early stages that are identical in tumor stage and grade.
