• using this model, we could hypothetically predict that a BED of approximately 68.8 Gy 10 would need to be delivered to patients with localized rectal cancer to achieve 100% local control with surgery

• using a high dose for fraction of 5 Gy to achieve a BED Gy 10 of 68.8 would require nine fractions, resulting in a BED of 117 Gy 3 .
