Partial nephrectomy is becoming the gold standard for renal tumors less than 4 cm but this treatment is much more controversial for larger T1 tumors. This large multicenter study suggests that it is safe to expand the indications of partial nephrectomy to include patients with T1N0M0 tumors up to 7 cm. However, careful patient selection remains necessary.
This study defines the general applicability of the UISS for predicting survival in patients with RCC. The UISS is an accurate predictor of survival for patients with localized RCC applicable to external databases. Although the UISS may be useful for patients with metastatic RCC, it may be less accurate in this subset of patients due to the heterogeneity of patients and treatments.
