In addition, higher pT‐stage, higher nuclear grade, the presence of peripelvic fat invasion, macrovascular and microvascular invasion, histological tumor necrosis and cytoplasmic expressions of HIF‐1α and HIF‐2α were significantly associated with a higher risk of disease recurrence or death from RCC in univariable analysis in both cohorts. The gene discussed is HIF1A; the disease is renal cell carcinoma.
