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 | Radiotherapy | * Patients undergo postoperative IMRT once daily, 5 days a week, for 6 weeks. The prescribed radiotherapy dose will be 60 Gy in 2 Gy once-daily fraction size (total of 30 fractions).~* Patients can consent to participate in either the randomized (physician chooses radiotherapy arm or radiotherapy \& cisplatin arm) or non-randomized (patient chooses radiotherapy arm or radiotherapy \& cisplatin arm) pathways | 1 | 27 | EG000 |
| Group 2 | Radiotherapy, Cisplatin | * Patients undergo postoperative IMRT once daily, 5 days a week, for 6 weeks. The prescribed radiotherapy dose will be 60 Gy in 2 Gy once-daily fraction size (total of 30 fractions)~* Patients also receive cisplatin 40 mg/m2 IV on Days 1, 8, 15, 22, 29, and 36 of radiation therapy (6 doses for a total of 240 mg/m2).~* Patients can consent to participate in either the randomized (physician chooses radiotherapy arm or radiotherapy \& cisplatin arm) or non-randomized (patient chooses radiotherapy arm or radiotherapy \& cisplatin arm) pathways | 0 | 11 | EG001 |
