Scientists use patients' own lung fluid cells to fight advanced cancer

This early-phase study tests a new treatment for people whose cancer has spread to the lining of the lungs (pleura) or who have mesothelioma. Doctors collect immune cells from the patient's own lung fluid, grow them in a lab, and then put them back into the chest through a tube along with a drug that boosts their activity. The goal is to see if this approach is safe and can shrink tumors or ease symptoms. The study involves about 10 participants and includes a short hospital stay.
