Prognostic significance of laterality in renal cell carcinoma: A population-based study from the surveillance, epidemiology, and end results (SEER) database.

Right-sided RCC is associated with more early-stage, low-grade disease and shows better CSS than left-sided RCC. Moreover, laterality remained as an independent prognostic factor for cancer-specific survival in subgroup of tumor size ≥10 cm RCC.
