Conclusions (1)

Literature shows that:

• Margin width is related to probability that residual tumor is left in situ, but NOT to the amount of tumor left in situ !

• Higher boost dose results in lower LR, especially in case of LARGE VOLUME

• BCT with boost for focally involved margins yields acceptable LR of about 3% at 5 yrs
