Morphologic parameters were correlated with survival in 121 renal cortical neoplasms including 116 carcinomas and five oncocytomas. An increasing nuclear grade was generally correlated with a significant decrease in disease‐free survival although no statistical difference was found between nuclear Grade 1 and 2 tumors. Similarly, a higher stage at diagnosis predicted a shorter disease‐free survival. Renal vein invasion adversely affected prognosis only for high nuclear grade carcinomas. Papillary and spindled carcinomas, independent of nuclear grade, were associated with a significant decrease in disease‐free survival compared to tumors with a solid pattern. Patients with large neoplasms (greater than 10 cm) had a significantly worse disease‐free survival than patients with tumors 10 cm or less. The prognostic significance of tumor cell type is less clear. Patients with oncocytomas had the best disease‐free survival compared with patients with tumors of other cell types. However, the difference in survival was not statistically significant for low‐grade tumors, suggesting that nuclear grade rather than cell type may be the more important determinant.
