Abstract
OBJECTIVES: Beta-blockers, a class of drugs commonly used to manage blood pressure, have been the subject of research regarding their relationship to prostate cancer (PC) risk, prognosis, and treatment. Beta-blockers reduce risk and improve the prognosis of PC. Perioperative use of a nonselective beta-blocker improves outcomes after radical prostatectomy. However, a related class of drugs, beta-2 adrenergic agonists, has received little attention in PC.</p>
METHODS: We studied the relationship of the beta-2 adrenergic agonist salbutamol to PC risk and survival. We analyzed Food and Drug Administration MedWatch data to determine whether salbutamol could influence the risk of PC. We used UK Biobank data to assess the effect of salbutamol on PC survival.</p>
RESULTS: Salbutamol significantly reduces PC risk, proportional reporting ratio, and 95% CI (lower bound; upper bound): 0.131 (0.11; 0.155) and improves prognosis. Mean survival was 7.35 years for subjects not taking salbutamol, and 10.5 years for subjects taking salbutamol (P = 0.041, log-rank test. To adjust for the effect of age, we performed proportional hazards regression, survival time-dependent variable, age, and salbutamol use independent variables. Salbutamol use was significantly related to survival time (P = 0.016) and independent of the significant effect of age (P < 0.001).</p>
CONCLUSIONS: We found a lower proportion of PCs in salbutamol-treated people, but we have not demonstrated that PC risk is reduced (there is no proof of causality). There is no causality relationship between salbutamol and the survival of patients with PC treated with salbutamol versus those not treated with the drug. Yet, there is a trend in favor of salbutamol-treated patient survival. Therefore, salbutamol and other beta-adrenergic agonists might represent a new class of drugs for the treatment of PC.</p>
