Malignant Pericardial Effusion: A Systematic Review.


ABSTRACT:

Background

Malignant pericardial effusion (Eff) is often asymptomatic and has an unknown prevalence, due to its occult presentation. The condition often is identified postmortem on autopsy, and it is associated with a poor prognosis. Given the late presentation of malignant pericardial Effs, a minimal volume of literature has examined the epidemiology, clinical characteristics, and outcomes of these complex patients. We conducted a systematic review to advance present understanding of this condition.

Methods

A search of 4 databases resulted in 41 case reports meeting criteria. Inclusion criteria were being a patient aged > 18 years who presented with pericardial Eff in the setting of malignancy. Intervention was medical and/or surgical therapy, and the outcome was mortality.

Results

For the 41 patients included, the median age was 54 years, and the majority were male patients (58%). Dyspnea was the leading symptom (90%), and cardiac tamponade was present in 78% of cases. Common cancers included lung, gastrointestinal, and renal neoplasms (59%). Pericardiocentesis occurred in 98% of cases, with a median fluid extraction volume of 1000 mL. Death occurred in 44%, primarily due to disease progression and/or metastasis.

Conclusions

This study presents the largest systematic review on malignancy-induced pericardial Effs to date. Notably, solid tumours, and specifically lung adenocarcinomas, are common culprits. Malignant pericardial Effs are often severe, with a majority of patients presenting with cardiac tamponade. Overall, treatment options are limited, and the associated mortality rate is high.
