This protocol covers patients who develop shortness of breath and a dry, nonproductive cough with a timing consistent with radiation pneumonitis — within 6 months of completing thoracic radiation therapy, most often within 12 weeks — in whom active lung infection has been excluded.
Radiation pneumonitis (RP) is the acute phase of radiation-induced lung injury. Its hallmark presentation is dyspnea — which can range from mild to severe — alongside a dry, nonproductive cough. Onset characteristically falls within 12 weeks of therapy completion, though it may occur up to 6 months after. Exclusion of lung infection is required before attributing symptoms to RP.
For significantly symptomatic radiation pneumonitis, once lung infection has been ruled out, most experts recommend a course of systemic glucocorticoids. The complete regimen — including dosing, duration, and tapering protocol — is available in the full structured protocol below.

RP occurs within 6 months of therapy (most often within 12 weeks), whereas RPF occurs > 1 year following therapy.
The most common symptoms are dyspnea, which can be mild to severe, and a dry, nonproductive cough.
However, most experts recommend systemic glucocorticoids to treat significantly symptomatic RP, provided that lung infection has been ruled out.
Patients may experience marked symptomatic relief, with reduction in cough, chest tightness, dyspnea, and fever, along with resolution of radiographic changes.
