Do we need dose constraints and DVH parameters?

Yes !

• Dose needed to control macroscopic tumors is high

• Dose levels different for primary tumors and node metastases

• Dose levels for elective targets 45-50Gy

• Evidence for importance of DVH parameters is constantly increasing

• Dose to OAR should be as low as possible “ALARA”

How to achieve the required dose gradients ?
