However, no significant correlations were observed between PTEN expression levels and clinical stage, pathological type (ccRCC vs. other type), or Fuhrman grade in our meta-analysis (OR = 1.918, 95% CI = 0.502–7.336; OR = 0.781, 95% CI = 0.249–2.453; OR = 2.415, 95% CI = 0.508–9.055). The gene discussed is PTEN; the disease is nonpapillary renal cell carcinoma.
