Lung cancer patients are particularly susceptible to malignant pleural effusion, when fluid collects in the space between the lungs and the chest wall. Researchers at the Helmholtz Zentrum München, in partnership with the German Center for Lung Research (DZL), have discovered a novel mechanism that causes this to happen. Their study, published in Nature Communications, now refines the mechanistic picture.

Malignant pulmonary effusion (MPE) frequently occurs in patients with metastatic breast or lung cancer. It involves a build-up of excess fluid in the pleural cavity, the area between the lungs and the chest wall, with accompanying malignant cells. The lung is surrounded by fluid, which can cause shortness of breath and chest pain, for example, and may even prove fatal.

“The cause is still not fully understood, which makes the search for suitable therapies more difficult,” explains Professor Georgios Stathopoulos, research group leader at the Institute of Lung Biology (ILBD) and the Comprehensive Pneumology Center (CPC) at Helmholtz Zentrum München. “However, we’ve now made significant progress in that direction.”

In their recent work, the team built on findings which they had also published in ’em>Nature Communications in May 2017.
