Balancing Breast Cancer Therapy and Cardiovascular Safety in a High-Risk Patient

Overview

This case study highlights successful management of a HER2-positive breast cancer patient with multiple cardiovascular comorbidities using a low-cardiotoxicity regimen and individualized perioperative antithrombotic therapy. Continuous cardiac monitoring and multidisciplinary team involvement ensured no cardiovascular complications during treatment.

Background

Cancer therapy-related cardiovascular toxicity (CTR-CVT) is a significant concern, especially in elderly breast cancer patients with pre-existing cardiovascular diseases such as hypertension, diabetes mellitus, and coronary heart disease. The 2022 ESC Guidelines emphasize comprehensive cardiovascular risk stratification and dynamic monitoring to balance oncologic efficacy and cardiovascular safety. Multidisciplinary teams play a crucial role in selecting appropriate anticancer regimens, managing perioperative antithrombotic therapy, and monitoring cardiac function to minimize cardiovascular risks during cancer treatment.

Data Highlights

ParameterPre-treatmentPost-treatment
Triglycerides (mmol/L)3.27Not reported
Blood Glucose (mmol/L)13.32Not reported
Left Ventricular Ejection Fraction (LVEF, %)6959
Cardiac Biomarkers (BNP, Troponin)NormalNormal
Axillary Lymph Nodes PositiveMetastasis present1/16 nodes positive post-surgery
Radiotherapy Heart DoseNot applicableMean heart dose <8 Gy

Key Findings

  • The patient had multiple cardiovascular risk factors including hypertension, diabetes mellitus, and coronary heart disease post-PCI.
  • A low-cardiotoxicity PTD regimen (pertuzumab, trastuzumab, docetaxel) was selected to minimize cardiac risk.
  • Perioperative antithrombotic management included withholding aspirin, discontinuing clopidogrel 5 days pre-surgery, and LMWH bridging based on low bleeding risk scores.
  • Regular cardiac monitoring with biomarkers, ECG, and echocardiography detected no cardiovascular complications throughout treatment.
  • Postoperative radiotherapy was delivered with strict heart dose constraints to reduce cardiac exposure.
  • Multidisciplinary team coordination enabled individualized treatment balancing oncologic efficacy and cardiovascular safety.

Clinical Implications

In breast cancer patients with pre-existing cardiovascular disease, selecting anticancer regimens with low cardiotoxicity and implementing individualized perioperative antithrombotic strategies are essential to minimize cardiovascular risks. Continuous cardiac function monitoring allows early detection of subclinical injury, facilitating timely intervention. Multidisciplinary collaboration is critical to optimize both oncologic and cardiovascular outcomes.

Conclusion

Comprehensive baseline cardiovascular assessment, careful regimen selection, rational perioperative antithrombotic management, and ongoing cardiac surveillance can successfully balance effective breast cancer treatment with cardiovascular safety in high-risk patients.
