Pericardial effusion complicating breast cancer

Area of Science:

• Oncology
• Cardiology
• Internal Medicine

Background:

• Metastatic breast cancer frequently involves the pericardium, leading to malignant pericardial effusion.
• Pericardial effusion can progress to cardiac tamponade, causing significant morbidity and mortality.
• Effective management strategies for pericardial effusion in breast cancer are critical.

Purpose of the Study:

• To evaluate the efficacy of pericardiocentesis and systemic therapy in managing pericardial effusions in metastatic breast cancer.
• To assess the impact of these interventions on patient survival and recurrence rates.
• To highlight the importance of considering cardiac tamponade in breathless cancer patients.

Main Methods:

• Retrospective analysis of 35 patients with metastatic breast cancer and pericardial effusions.
• Treatment included pericardiocentesis, endocrine therapy, or chemotherapy.
• Assessment of procedural success, need for further interventions, and survival outcomes.

Main Results:

• 63% of patients presented with cardiac tamponade, with rapid relief following pericardiocentesis.
• 82% required no further local treatment after the initial procedure.
• Median survival was 13.2 months, with no pericardial relapses, indicating prognosis is tied to the underlying disease.

Conclusions:

• Pericardiocentesis is a highly effective and often curative procedure for cardiac tamponade in breast cancer patients.
• Systemic therapy complements pericardiocentesis, potentially prolonging survival.
• Early recognition and management of cardiac tamponade are essential for improving outcomes in advanced cancer.
