Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This randomized, prospective, multicenter phase II/III trial will study the reduction of radiation volume by eliminating radiotherapy (RT) to the elective neck using strictly defined surgical and radio-oncological standards to reduce radiotherapy-related long-term side effects without affecting locoregional control.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This study aims to determine whether it is possible to achieve an individual target volume concept that eliminates elective irradiation of uninvolved lymph drainage areas while maintaining clearly defined surgical standards and using modern imaging and radiation techniques. The aim of this study is to achieve reduced late toxicity without compromising locoregional control.

Patients will be randomized to: either RT to primary tumor region, regions with lymph node metastases and elective nodal irradiation (control arm) or RT to primary tumor region and regions with lymph node metastases without elective nodal irradiation (investigational arm)

A two-stage design was chosen for this purpose.

Phase II:

A randomized phase II study whose primary endpoint is the 1-year percutaneous endoscopic gastrostomy (PEG) tube dependence rate will be performed first.

Phase III:

If the primary endpoint of the phase II study is met and the interim analysis shows no increase in the locoregional recurrence rate in the study/investigational arm, the study will be continued as a phase III study whose primary endpoint is the locoregional control rate.

6. No distant metastases (cM0)
7. Age ≥ 18 years, no upper age limit
8. Eastern Cooperative Oncology Group (ECOG) ≤ 2
9. Patients who understood protocol contents and are able to behave according to protocol
10. Signed study-specific consent form prior to therapy
11. Start of radiotherapy at least 6 weeks after last tumor-specific surgery (e.g. resection primary tumor, neck dissection, excluded are surgeries according to wound healing complications)

Exclusion Criteria

1. macroscopic incomplete resection R2
2. Distant metastases (cM1)
3. Radiologically or histologically proven early recurrence after surgery (time frame from surgery to start of radio(chemo)therapy)
4. Lymph node metastases in \> 3 lymph node level
5. pregnant or lactating/nursing women
6. fertile patients that are not willing to use highly effective methods of contraception (per institutional standards) during treatment
7. Any condition potentially hampering compliance with the study protocol and follow-up schedule
8. On-treatment participation on other clinical therapeutic trials
9. Prior tumor-specific therapy any other than surgery (like prior radiotherapy in the head and neck region, prior chemo- or immunotherapy (neoadjuvant/induction))
10. Patients who have contraindication for MRI and CT with contrast agent (both)
11. Prior (\> 2 months before beginning of radio(chemo)therapy) neck dissection or surgery in the head and neck area affecting lymph drainage
12. History of another primary malignancy except for malignancy treated with curative intent and with no known active disease ≥5 years before diagnosis of head and neck cancer, adequately treated non-melanoma skin cancer or lentigo maligna without evidence of disease, adequately treated carcinoma in situ without evidence of disease
