FIGURE 1. Patient examples with early-stage non-small cell lung cancer (NSCLC) in central tumor locations: (A) tumor adjacent to the aortic arch, (B) tumor adjacent to the left ventricle, and (C) tumor in a hilar location, extending to the chest wall. The patient in panel (C) is the patient who developed a rib fracture after treatment.

FIGURE 4. Biological effective doses (BED) tumor (α/β = 10) versus 2-year local control probability (A), and BED normal tissue (α/β = 3) versus severe toxicity (B), data derived from Table 4; present study marked by circle. BED, biologically effective dose; BED = D (1 + d/(α/β)), where D is total dose, d is dose per fraction, and the α/β ratio is assumed to be 10 for tumor tissue and 3 for normal tissues.
