Table 1.

Planning dose constraints for the PTV, OARs and normal tissue. Dp = prescribed dose. In cases where fulfilling all constraints was impossible, the responsible oncologist decided whether target coverage or OAR constraints should be compromised.

Volume Dose Constraint
PTV V95% > 98%
Lungs V5Gy < 65%
V20Gy < 35%
Dmean < 20 Gy
Heart V30Gy < 40%
Esophagus Dmean < 34 Gy
Spinal canal Dmax < 50 Gy
Brachial plexus Dmax < 66 Gy
Patient body Dmax < Dp · 1.07
