Location of Extrarenal Tumor Extension Does Not Impact Survival of Patients With pT3a Renal Cell Carcinoma

In contrast to previously reported observations, in our cohort of surgically treated patients with pT3a renal cell carcinoma the location of extrarenal extension was not an important prognosticator of cancer specific mortality. Based on our findings we confirm that perinephric and/or sinus fat should be similarly subclassified in the primary tumor staging system.
