Background:

Large and symptomatic pericardial effusions (PE) can complicate various malignancies and have increased incidence in specific patient subsets. We sought to evaluate the factors determining recurrence in these patients.

Methods:

All data pertaining pericardiocentesis (PC) for large PE in cancer patient population performed and enrolled over a decade 2010-2020 in a Cancer Center Pericardiocentesis Registry were analyzed. Descriptive statistics were done to report mean and standard deviation for various variables and Kaplan-Meyer curves were used to analyze survival.

Results:

Of the total 469 patients who had PC, 54 (11.5 %) patients had recurrent PE. Mean age of the patient cohort was 48 ± 16.5 years. All patients met the criteria for large PE by echocardiography while 50/54 (92.5 %) had clinical and echocardiographic signs of tamponade at initial PC. Recurrent effusion occurred after mean of 80.5 ± 185 days. Advanced stage (III and IV) solid malignancies were present in 35/54 (65 %) while 19/54 (35 %) had hematological cancers. Recurrence of PE was observed most commonly in lung and breast cancer patients with a cumulative percentage of 37 % (20/54). Laboratory data showed mean hemoglobin of 10.4 ± 1.97 g/dl, platelet count of 195 ± (126) K/uL, INR of 1.23 ± 0.2, and creatinine of 0.88 ± 0.3 mg/dl. PC was performed with subxiphoid approach in 37/54 (68.5 %) and lateral approach in 17/54 (31.5 %) patients. The drain was kept for 4.3 ±1.7 days after initial and 4.8 ±1 days after subsequent PC. Pericardial fluid analysis showed malignant in 42/54 (77.7%) and inflammatory effusion in 12/54 (23.3 %) patients after initial PC. In 13/54 (24 %) patients, anti-inflammatory drugs (NSAIDs or colchicine) were used due to inflammatory nature of effusion either clinically or by analysis of fluid. Mortality at 9 months from the time of initial PC was 43/54 (79.6 %) and was driven by underlying malignancy and treatment related complications (sepsis and renal failure).

Conclusions:

Patients with advanced stage cancer (especially lung and breast) are more likely to present with recurrent pericardial effusion and tamponade. Pericardiocentesis appears to have a palliative role in this population with increased disease and treatment-related mortality.
