RP is characterized histologically by diffuse alveolar damage and acute vascular permeability induced by direct cytotoxic effect and oxidative stress, leading to the production of proinflammatory, profibrogenic and proangiogenic cytokines.\n\nPatients with Interstitial Lung Disease (ILD) are at increased risk of developing lung cancer compared to the general population. Management of patients with lung cancer in the setting of a concomitant ILD is complex, as these patients are usually not good candidates for surgery or immunotherapy. In addition, patients with ILD, particularly fibrotic ILD, are also reportedly at increased risk of treatment-related toxicity from RT.\n\nIn the present study, investigators will test the following hypotheses:\n\n1. The use of NAC with RT in patients with underlying ILD will lead to a clinically meaningful reduction in grade 2-5 dyspnea (as per Common Terminology Criteria for Adverse Events \\[CTCAE\\] version 5.0).\n2. The use of corticosteroids with RT in patients with underlying ILD will lead to a clinically meaningful reduction in grade 2-5 dyspnea (as per CTCAE version 5.0).'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'minimumAge': '18 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* Lung cancer or 1-2 oligometastatic pulmonary lesions planned for radical intent radiotherapy \\[minimal Biologically Effective Does (BED) of 48 Gy10 (Gray) or biological equivalent\\].\n* Pathologically (histologically or cytologically) proven diagnosis of cancer is not required, but strongly recommended.\n\n * If the risk of biopsy is unacceptable, pathologic confirmation is not required providing there is growth over time on Computed Tomography (CT) imaging and/or Fluorodeoxyglucose (FDG) avidity that is strongly suggestive of malignancy.\n* Fibrotic Interstitial Lung Disease (ILD) of any subtype, as diagnosed by a respirologist and confirmed by central review\n* Eastern Cooperative Oncology Group (ECOG) performance status 0-3\n* Age ≥ 18\n* Life expectancy \\> 6 months\n* Patients are allowed to receive anti-fibrotic agents used in the treatment of Idiopathic Pulmonary Fibrosis (IPF) or non-IPF fibrotic ILD (e.g. nintedanib, pirfenidone) and/or corticosteroids, if those are part of their current ILD treatment regimen.
