Overall Survival after Partial Versus Radical Nephrectomy for a Small Renal Mass: Systematic Review of Observational Studies

However, because residual confounding could be present despite adjustment for measured covariates, another randomized trial of partial vs radical nephrectomy may be needed to confirm or refute the findings of EORTC 30904.
