Beta-Blockers Up Ovarian Cancer Survival in Study
(HealthDay News) — Nonselective beta-blocker use is associated with improved overall survival among patients with epithelial ovarian, primary peritoneal, or fallopian tube cancers (collectively, epithelial ovarian cancer [EOC]), according to a study published online August 24 in Cancer.
Jack L. Watkins, PharmD, from the University of Texas MD Anderson Cancer Center in Houston, and colleagues examined the impact of beta-adrenergic blockade on the clinical outcome of women with EOC. They performed a multicenter review involving 1,425 women with histopathologically confirmed EOC (median age, 63 years).
The researchers found that of the 269 patients who received beta-blockers during chemotherapy, 71.7% were receiving beta-1-adrenergic receptor selective agents, while the rest received nonselective beta antagonists. Indications for beta-blocker use included hypertension as well as arrhythmia and postmyocardial infarction management. Median overall survival (OS) was 47.8 vs. 42 months for those receiving any beta-blockers vs. nonusers, respectively. The median OS was 94.9 vs. 38 months for those receiving nonselective beta-blockers vs. beta-1-adrenergic receptor selective agents, respectively. Across all groups, hypertension correlated with decreased OS vs. no hypertension.
"Use of nonselective beta-blockers in patients with EOC was associated with longer OS," the authors write. "These findings may have implications for new therapeutic approaches."
