Furthermore, shorter OS was found in patients with diabetes: 33 months vs. 104 months (p = 0.041), higher than median morning cortisol levels: 33 months vs. 92 months (p = 0.031), and tumors with Ki67 > 20%: 19 months vs. 65 months (p = 0.036), compared to non-diabetic patients, patients with lower than median morning cortisol, and tumors with Ki67 < 20%, respectively. The gene discussed is MKI67; the disease is diabetes mellitus.
