Beta-Blockers Not Effective in Reducing Anxiety Among Cancer Survivors
Key Takeaways
- Beta-blockers don't reduce anxiety in cancer survivors.
- Patients on beta-blockers reported lower quality of life.
- More research is needed to find effective treatments.

Introduction
Beta-blockers, typically prescribed for heart conditions, were recently studied for their potential impact on anxiety and intrusive thoughts among cancer survivors. The results from a comprehensive study suggest these medications may not be effective in this new role.
Study Overview
A recent analysis published in BMC Cancer used emulated trials to evaluate whether beta-blockers could reduce anxiety and intrusive thoughts in cancer survivors. The study specifically looked at patients who had been diagnosed with colon, prostate, or rectal cancer.
Methodology
Researchers analyzed data from patient-reported outcomes gathered from three large cohort studies in Sweden. These were paired with information on beta-blocker prescriptions from the Swedish Prescribed Drug Register. Two emulated randomized controlled trials (RCTs) were created to compare the effects between those who took beta-blockers and those who did not.
Participants and Groups
The first trial followed patients for one year after their cancer diagnosis, while the second trial tracked them over two years. Patients were grouped based on whether they began beta-blocker therapy or not. The active group comprised those who received beta-blockers between the baseline and follow-up periods, while the control group included those who did not.
Findings
No significant differences were found between the active and control groups regarding the primary endpoints of intrusive thoughts frequency and severity. In the first trial, beta-blocker users showed a slightly lower prevalence of intrusive thoughts and severity but these differences were not statistically significant. The second trial yielded mixed results; while beta-blocker users had higher prevalence of intrusive thoughts, their severity was lower compared to non-users.
Secondary Outcomes
The research also examined secondary endpoints such as depressed mood, quality of life, and anxiety levels. Both trials indicated that beta-blocker users generally experienced higher levels of anxiety, depressed mood, and lower quality of life, although the results varied slightly between the two trials.
Implications
Despite previous studies suggesting a potential benefit, this new research indicates that beta-blockers may not provide a significant protective effect against anxiety and intrusive thoughts in cancer survivors. This highlights the need for further interventional trials to explore other therapeutic options without the confounding factor of cardiovascular disease treatment.
Conclusion
The findings suggest that beta-blockers are not effective in reducing anxiety or intrusive thoughts among cancer survivors. More research is needed to identify better treatment options for improving mental health and quality of life in this patient population.
Next Steps
Future studies should focus on long-term effects, explore different cancer types, and investigate other potential medications. This will help to provide a clearer understanding and more effective treatments for the mental health challenges faced by cancer survivors.
