Symposium
SBRT IN LUNG - CHOICES AND THEIR IMPACT ON RELATED
UNCERTAINTIES
08:45 - 10:00 | ROOM 1
This symposium will review current practice of SBRT in lung from different angles, i.e. view of medical
physics, radiation oncology and radiation biology. The impact of dose calculation and fluence optimiza-
tion on outcome will be addressed, together with aspects of treatment plan robustness against motion.
Furthermore dose effect relationships for local tumor control in NSCLC will be presented, and the
pitfalls of current treatment/prescription protocols with in-homogeneous dose distributions within the
PTV. In this context also the impact of dose profiles on the effective dose delivered to the GTV will be
discussed. Furthermore, the balance between maximizing local tumor and minimizing the risk of toxicity
will be covered in this symposium. The different “Rs” of radiobiology will be reviewed together with
limitations of the LQ model at high doses, since this is often applied for relating morbidity endpoints
with current knowledge on toxicity. Finally, new aspects of “high dose biology” will be presented.
