Parotids: other updates…

6w

• Utrecht data (221 pts), stimulated flow rates 6w, 6m, 1y. • 3DCRT (n=157) vs IMRT (n=64) • NTCP end point: reduction < 25% baseline • Different behaviour between IMRT and 3D • Spatial effects (different dose distribution @ same Dmean)…more important for early reactions
