Detailed pathologic examination of 120 consecutive CCRCCs showed renal sinus invasion in 59 (49%) tumors, with 53 (44%) involving the renal vein and 6 (5%) invading renal sinus fat alone. By contrast, only 30 (25%) tumors invaded the renal capsule, and all of these also had renal sinus invasion. [26]
