Conclusions (2)

Thus: • Since estimated risk on large volume residual disease is a more important risk factor for LR than probability on residual disease:

• High boost dose and / or re-excision: only if high risk on LARGE VOLUME residual disease

• Risk factors like Young Age, LVI, Grade, TN, seem to be associated with larger residual VOLUMES, and require a boost.
