PURPOSE: This report is a patterns-of-failure analysis of resected renal cell carcinoma (RCC) performed to determine the relative incidences of local failure (LF) and distant failure, to identify the pathologic features predicting for each using a multivariate analysis, and to assess the relative impact of each form of failure on overall survival (OS). In this way, the potential value of and selection of patients for adjuvant local and/or systemic therapy can be better evaluated. MATERIALS AND METHODS: The records of 172 patients with unilateral, nonmetastatic RCC who were treated with definitive surgery between 1978 and 1988, and who had a minimum follow-up duration of 1 year, were identified through the Memorial Sloan-Kettering tumor registry. Distribution by stage included T1, 10 patients; T2, 102; T3a, 32; T3b, 27; and T4, one. The incidences of positive lymph nodes (LNs) and positive margins were 5.8% and 6.4%, respectively. RESULTS: LF developed in only six patients, yielding a 7-year actuarial incidence of 5%. In this subset, four patients developed distant metastases (DM), three occurring concurrently with or before LF. DM developed in 30 patients, yielding a 7-year actuarial incidence of 26%. Among the variables that had an impact on the development of DM according to univariate log-rank tests, only positive LNs (P = .026) and renal vein extension (P = .001) remained as significant independent prognosticators. The overall 7-year actuarial survival rate was 80%. Eleven patients died of RCC during follow-up, nine of whom (82%) died of metastatic disease. CONCLUSION: LF is rare following surgical management of RCC, and shows no clear causal relationship with the development of DM. Patients die of DM, and not LF. These data do not support the role of adjuvant radiation therapy in this disease. Patients with LN involvement or renal vein extension have a significantly increased risk for developing DM, and are therefore appropriate candidates for trials investigating systemic therapy.
