The impact of perioperative β blocker use on patient outcomes after primary cytoreductive surgery in high-grade epithelial ovarian carcinoma



Physiological condition or, more often "physiological conditions" is a term used in biology, biochemistry, and medicine. It refers to conditions of the external or internal milieu that may occur in nature for that organism or cell system, in contrast to artificial laboratory conditions.
Human physiology is the science of the mechanical, physical, and biochemical function of humans, and serves as the foundation of modern medicine. As a discipline, it connects science, medicine, and health, and creates a framework for understanding how the human body adapts to stresses, physical activity, and disease.

Highlights

Stress is associated with poor prognosis in patients with solid tumors.
β blocker can lower down the physiologic stress response.
Use of perioperative β blocker after primary cytoreductive surgery for ovarian cancer associated with better overall survival

Abstract

Objective

To quantify the impact of perioperative β blocker use on survival after primary cytoreductive surgery for epithelial ovarian cancer.

Methods

We conducted a multi-center retrospective study of all women who underwent primary cytoreductive surgery for ovarian cancer (2000 − 2010). One institution had routinely used perioperative β blockers for patients “at risk” for coronary events. The other institution did not routinely use perioperative β blockers. Demographic, operative, and follow up data were collected. Cox proportional hazards models were used to assess the effect of β blockers on progression-free interval (PFI) as well as overall survival (OS).

Results

Out of 185 eligible patients, 70 received β blockers and 115 underwent cytoreductive surgery without perioperative β blockers. Both groups were similar in demographics. A history of hypertension was present more often in the β blocker group compared to the group that did not receive β blockers (22% and 6%, p = 0.002). PFI in β blocker group was greater at 18.2 vs. 15.8 months (p = 0.66). The OS in the β blocker group was significantly higher at 44.2 vs. 39.3 months (p = 0.01). In multivariate analysis, perioperative β blocker use was associated with significant improvement in OS (HR 0.68 (0.46–0.99); p = 0.046).

Conclusion

Our study showed an association between perioperative β blocker use and longer overall survival in patients undergoing primary ovarian cancer cytoreductive surgery. A prospective randomized clinical trial in this population would further validate these results.
