Development of Pericardial Effusion in Non-small Cell Lung Cancer Is Associated with the Presence of EGFR/ALK Mutations

Summary

Background:

No specific clinical or histological factors are recognized to be associated with the development of pericardial effusion in non-small cell lung cancer (NSCLC) other than a metastatic disease.

Objectives:

To assess whether specific clinical and histological features are associated with development of pericardial effusion in patients with NSCLC.

Methods:

A consecutive cohort of patients with NSCLC who presented with symptomatic pericardial effusion 2014–2017 was compared to a control group of patients with advanced NSCLC without pericardial effusion.

Results:

The 27 patients in the effusion group were generally younger, more often female, and with a higher percentage of never-smokers, compared to the 54 patients of the control group. Epidermal growth factor receptor/anaplastic lymphoma kinase (EGFR/ALK) mutation tumors were found in 48% of patients in the effusion group vs. 25% in the control group. In the multivariate analysis, the unadjusted odds ratio (OR) for the development of pericardial effusion in patients with somatic mutations was significantly higher compared to wild type tumors (OR 2.65, 95% confidence interval 1.00–7.00). However, a suspected association between pericardial effusion and mutation status was found to be confounded by age. While a high rate of recurrence was observed when pericardiocentesis was initially performed (9/17, 53%), no recurrence was documented when pericardial window procedure was performed (total of 17 patients).

Conclusions:

Patients with EGFR/ALK mutations may be at higher risk for the development of pericardial effusion; therefore, attending physicians need to be aware and have a high index of clinical suspicion
