2 FIGURE 1 Isodose distribution showing the 20 Gray (Gy), 40 Gy, and 60 Gy isodose lines on a coronal computed tomography (CT) slice. Heterogeneity correction was not used for dose calculation. Portions of the rib, chest wall, neurovascular bundle, pleura, and pulmonary parenchyma receive doses in excess of 40 Gy in three fractions.

3 FIGURE 2 Follow-up computed tomography (CT) (bone windowing) demonstrating changes at 16 months postradiotherapy including cortical thinning (arrow), suggestive of osteonecrosis, and fibrosis of pulmonary parenchyma, pleura, and chest wall.

4 FIGURE 3 Progression to fracture (arrow) and further progression of parenchymal pulmonary fibrosis 29 months postradiation therapy (RT). Journal of Thoracic Oncology 2009 4, DOI: ( /JTO.0b013e3181ae2962) Copyright © 2009 International Association for the Study of Lung Cancer Terms and Conditions

5 FIGURE 4 Actuarial proportion of patients free of fracture as a function of time since treatment. The exes mark patient deaths, tick marks show censored patients (last follow-up), and dashed lines show 95% confidence interval.
