[Radiation pneumopathy. Our experience in the treatment of Hodgkin's disease with mantle-shaped field radiotherapy].

The literature of the radiation pneumonitis is reviewed from the standpoint of the pathogenesis, histopathology and dependent parameters of the disease. A series of 125 patients treated with mantle fields for Hodgkin's disease between 1972/80 is studied. The radiation pneumonitis developed radiologically in 28 patients (22,4\%); in 20 (72\%) was asymptomatic. The incidence of pneumonitis against the time of onset of the disease, reveals a peak about the first three months after the end of radiotherapy. No significative variations of incidence of disease are seen in two groups of patients treated respectively with and without chemotherapy (20\% and 26\%). Frequency diagrams of pneumonitis as a function of the calculate values of the dose for TD, rets, TDF, show a significant correlation with the ranges of doses expressed in TDF.
