Approximately 50% of patients with metastatic disease develop a malignant pleural effusion (MPE). Prompt clinical evaluation and treatment to achieve successful palliation are the main goals of management of MPE. Optimal treatment is still controversial and there is no universal standard approach. Management options include observation, thoracentesis, indwelling pleural catheter (IPC) or chest tube placement, pleurodesis, and surgical pleurectomy. The treatment for each patient should be based on symptoms, general condition, and life expectancy.
