A trial looking at 2 ways to treat a build up of fluid around the lung (OPTIMUM)

This trial is comparing two ways to treat a build up of fluid around the lung. It is for people who have a build up of this fluid because of their cancer.

The lung is covered with 2 sheets of tissue called the pleura. These normally produce a small amount of fluid which lubricate the lungs and helps us to breathe. When cancer spreads to the pleura it causes too much fluid to be made. This collection of fluid is called a pleural effusion.
