Clinical Trial Summary

In the radiotherapeutic treatment of lung cancer, the dose that can be safely applied to the tumour is limited by the risk of radiation induced lung damage. This damage is characterized by parenchymal damage and vascular damage. In rats, we have found that radiation-induced vascular damage results in increased pulmonary artery pressure. Interestingly, the consequent loss of pulmonary function could be fully explained by this increase in pulmonary artery pressure. We hypothesize that also in patients a radiation induced increase in pulmonary artery pressure can be observed after radiotherapy, which may contribute to the development of radiation pneumonitis.

The objective is to test the hypothesis that radiotherapy for lung cancer induces an increase in pulmonary artery pressure.
