3. In patients with early stage lung cancer, stereotactic body radiation therapy (SBRT) has greatly improved survival in patients unable to undergo surgery. In tumors <3 cm, protocols that deliver >100 Gy 10 BED have demonstrated significantly improved survival, when compared with doses <100 Gy 10. What is the BED of the following protocol? Would you suggest increasing the dose, or does it appear adequate, assuming the given information? What would you expect as the most likely side effect of therapy for this patient? 3 fractions of 15 Gy delivered every other day.
