1 Outcomes of Stereotactic Ablative Radiotherapy for Centrally Located Early-Stage Lung Cancer 
Cornelis J.A. Haasbeek, MD, PhD, Frank J. Lagerwaard, MD, PhD, Ben J. Slotman, MD, PhD, Suresh Senan, MRCP, FRCR, PhD  Journal of Thoracic Oncology  Volume 6, Issue 12, Pages (December 2011) DOI: /JTO.0b013e31822e71d8 Copyright © 2011 International Association for the Study of Lung Cancer Terms and Conditions

2 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.

5 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.
