View original scientific description
The goal of this clinical trial is to compare the effectiveness of a navigation-based multilevel intervention (ENDURE) with treatment as usual (TAU) to improve the initiation of guideline-adherent postoperative radiation therapy among patients with head and neck cancer. The main questions the trial aims to answer are: 1. Does ENDURE improve initiation of timely PORT relative to treatment as usual? 2. What are the mechanisms through which ENDURE improves timeliness to treatment? 3.
Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria

- No history of radiation therapy for treatment of HNSCC in the definitive or adjuvant settings that would, at the discretion of the enrolling clinician, affect the patient's need for adjuvant RT.
- Plan for curative intent surgery at one of the participating centers
- Plan for PORT (regardless of whether it is at the surgical center) with or without concurrent chemotherapy following curative intent surgery based on the expectation of at least one of the following adverse features on final pathologic evaluation: pT3 or pT4 primary, N1 or greater nodal disease, perineural invasion (PNI), or lymphovascular invasion (LVI).
Exclusion criteria
- Inability to speak or read English or Spanish.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
