Systolic and diastolic blood pressure, prostate cancer risk, treatment, and survival. The PROCA‐life study

Abstract

Abstract Background Inflammation has been linked to prostate cancer and hypertension, but it remains equivocal whether elevated blood pressure (BP) influence prostate cancer risk and survival. Method Using Cox regression models, we examined the association between prediagnostic BP and prostate cancer risk among 12,271 men participating in the Prostate Cancer throughout life (PROCA‐life) study. Systolic and diastolic BP were measured. A total of 811 men developed prostate cancer, and followed for additional 7.1 years, and we studied the association between prediagnostic BP and overall mortality among patients with prostate cancer. Results Men (>45 years) with a systolic BP >150 mmHg had a 35% increased risk of prostate cancer compared with men with a normal systolic BP (150 mmHg had a 49% increased overall mortality compared with men with a normal systolic BP (HR 1.49, 1.06–2.01). Among patients with prostate cancer treated with curative intent, those with a high diastolic BP (>90 mmHg) had a threefold increase in overall mortality risk (HR 3.01, 95% CI 1.40–6.46) compared with patients with a normal diastolic BP (<80 mmHg). Conclusion Our results support that systolic and diastolic BP are important factors when balancing disease management in patients with prostate cancer.
