Prediction of progression after radical nephrectomy for patients with clear cell renal cell carcinoma

In patients with clear cell RCC, tumor stage, regional lymph node status, tumor size, nuclear grade, and histologic tumor necrosis showed statistically significant associations with progression to metastatic RCC. The authors present a scoring algorithm based on these features that can be used to predict disease progression after patients undergo radical nephrectomy for clinically localized clear cell RCC.
