Radiation pneumonitis: A new approach to the derivation of time-dose factors

Abstract: A series of 51 patients treated with 92 separate lung fields for metastatic pulmonary disease between 1958 and 1971 is reviewed. The treatment data are converted into nominal single doses (NSD) and a newly derived formula for estimated single doses (ED). The 5% incidence level of pneumonitis without dactinomycin is 770 rets (NSD) and 510 rets (ED) and with dactinomycin, 520 rets (NSD) and 450 rets (ED). A safe treatment regimen for avoiding radiation pneumonitis is 1500 rads in 10 fractions with dactinomycin a… Show more

“…Animals that did not receive corticosteroids died over a period of many weeks, 50% survival occurring at -18 wk, which is similar to previous reports (14,15). Death at this time has been shown to be due to radiation pneumonitis (15). Survival at 19 wk was significantly enhanced in the group that received corticosteroids, P < 0.02.…”

“…A resposta do pulmão à radiação depende do volume do órgão irradiado 1 , dose total 3,4 , fracionamento da dose 1,5 e da taxa de dose utilizada (6,7) . Dessa forma, as alterações histopatológicas observadas no pulmão irradiado podem variar desde edema e congestão da parede alveolar até a deposição de fibras colágenas e fibrose pulmonar 3,8 .…”

“…The lack of concordance between prevention of acute irradiation effects (associated with elevated levels of some cytokines) and the late effects of ionizing irradiation may indicate disparate molecular mechanisms for each type of injury. 31,32 Alternatively, irradiation damage associated with the late effects of ionizing irradiation may be attributable to molecular mechanisms common to the early effects, but not yet identified.…”
