Objective:

To evaluate the balance between cancer treatment efficacy and cardiovascular safety in a breast cancer patient with pre-existing cardiovascular conditions, specifically using a low-cardiotoxicity regimen.

Key Findings:

• No cardiovascular complications occurred during treatment.
• Post-treatment left ventricular ejection fraction was 59%.
• The selected PTD regimen minimized cardiac risks while effectively treating cancer, with a significant reduction in tumor size.

Interpretation:

Comprehensive risk assessment and tailored treatment strategies, guided by a multidisciplinary team, can effectively manage cancer therapy-related cardiovascular risks in patients with pre-existing conditions.

Limitations:

• Findings are based on a single case study, limiting generalizability.
• Long-term outcomes and effects of the treatment regimen on cardiovascular health remain to be evaluated, particularly in terms of late-onset complications.

Conclusion:

Balancing cancer treatment and cardiovascular safety is achievable through individualized assessment and continuous monitoring, ensuring optimal outcomes and minimizing risks.
