[Indices of external respiration in patients with Hodgkin's disease long after irradiation of the mediastinum].

The function of the respiratory organs using the results of ventilation, gas exchange and roentgenopneumopolygraphy, was analysed in 98 Hodgkin's disease patients in a state of a prolonged remission (5-12 yrs.) after radiation therapy of the mediastinum. Pulmonary ventilation disorders were revealed in 43.9% of the patients. The degree of ventilation disorders depended on the degree of expression of radiation fibrosis in the paramediastinal regions of the lungs. Usually there were no clinical signs of the revealed changes.
