Malignant Pleural Effusion: Diagnosis and Treatment—Up-to-Date Perspective

Abstract

Malignant pleural effusion is the presence of malignant cells within the pleural fluid, representing the second most common cause of pleural exudate. Although diagnostic methods and management techniques for malignant pleural effusion have dramatically improved over the decades, the current treatment is still palliative, aiming to remove pleural fluid, possibly prevent its recurrence, and alleviate symptoms through a wide range of available procedures. Treatment should be tailored to the individual patient, considering comorbidities, size of the effusion, rate of fluid accumulation, underlying cardiac or respiratory conditions, rate of recurrence, presence of loculations or trapped lung, tumor characteristics, cancer type, and patient preferences. This manuscript aims to review the available literature and to present the latest evidence on malignant pleural effusion management in order to provide an updated perspective on its diagnosis and treatment.
