To assess the effect and toxicity of intrapleural administration of hypertonic cisplatin for malignant pleural effusion in patients with non-small-cell lung cancer.

The lung was fully expanded by a thoracostomy using a chest tube with a double lumen, and then the patients were enrolled into the trial.First, premedication including antiemetics and hydration were performed. Thereafter, 75 mg of body surface area of cisplatin in 50 ml of distilled water was injected through a chest tube.The patients were asked to change position (supine and bilateral decubital) from time to time for 30 minutes. The chest tube was clamped for 48 h and then the tube was declamped and allowed to drain. When the drainage effusion was less than 100 ml a day, the chest tube was removed. Any patient whose drainage effusion continued for over 2 weeks was withdrawn from the trial and was also judged to be a nonresponder.
