The document provides guidelines for managing malignant pleural effusions. It discusses:
- Lung cancer and breast cancer are the most common causes of malignant pleural effusions.
- Effusions are usually symptomatic, with dyspnea being most common. Massive effusions often indicate malignancy.
- Management depends on symptoms, primary tumor type, and lung re-expansion. Options include observation, therapeutic aspiration, tube drainage with sclerosant, or thoracoscopy with pleurodesis. Tube drainage and pleurodesis is preferred to prevent recurrence, unless lung is trapped.
