Groups2
Neither group, or both, names a comparator, so the groups keep ClinicalTrials.gov's order.
| Group | Title | Description | With the outcome | Analysed | ClinicalTrials.gov code |
|---|---|---|---|---|---|
| Group 1 | 70.2 Gy | 70.2 Gy 3D-CRT/IMRT: Radiation will be delivered via 3D conformal radiation therapy (3D-CRT) or intensity modulated radiation therapy (IMRT) in 1.8 Gy minimum dose fractions to a total of 70.2 Gy in 39 Fractions . All fields treated once daily, five fractions per week. No more than 2% of the planning target volume and none of the clinical target volume may receive less than 70.2 Gy. | 30 | 744 | EG000 |
| Group 2 | 79.2 Gy | 79.2 Gy 3D-CRT/IMRT: Radiation will be delivered via 3D conformal radiation therapy (3D-CRT) or intensity modulated radiation therapy (IMRT) in 1.8 Gy minimum dose fractions to a total of 70.2 Gy in 44 Fractions . All fields treated once daily, five fractions per week. No more than 2% of the planning target volume and none of the clinical target volume may receive less than 79.2 Gy. | 43 | 737 | EG001 |
