Table 1.
Dose objectives for all regions of interest.
| ROI | Objectives |
|---|---|
| Brain stem | D0.1cc = 54 Gy |
| Spinal cord | D0.1cc ≤ 44–45 Gy |
| Mandible | D1cc = 70–73.5 Gy |
| Larynx |
Dmean = 44 Gy D1cc = 73.5 Gy |
| Thyroid | V45 Gy < 50% |
| Esophagus | D1cc = 45 Gy |
| Parotids |
Dmean ≤ 26 Gy V30 Gy < 50% |
| Salivary glands | Dmean ≤ 35 Gy |
| Ring 1 | D2% = 95% prescribed dose to PTV3 |
| Ring 2 | D2% = 80% prescribed dose to PTV3 |
| PTVn | Dmin = 80% prescribed dose to PTVn |
| PTVn eval | D95% = 95% prescribed dose to PTVn |
| Dmin = 90% prescribed dose to PTVn | |
| D2% = 105% prescribed dose to PTVn | |
| Uniform dose = prescribed dose to PTVn |
Abbreviations: ROI = region of interest; PTV = planning target volume.
