Published on: November 10, 2023
[Conservative therapy of malignant pleural effusion]
Abstract:
The nonsurgical treatment of malignant pleural effusion is palliative in principle. This aim must be achieved with a minimum of side effects and risks to the patients. Before treatment, a clear histologic diagnosis must be made. Thoracoscopy offers a fast and safe result with a more than 90% reliability. Systemic cytotoxic treatment and local procedures are available. Using pleurodesis, talkum is clearly superior to tetracycline in achieving a very low recurrence rate. The median survival in 287 patients was 9 months.
