Surgery and IMRT for Head and Neck Cancer
(SUPERIOR Trial)
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial investigates treatments for head and neck cancer when the main tumor is undetectable, but cancer appears in the lymph nodes. It examines whether less radiation or only surgery (including Lymphovenous Anastomosis, Vascularized Lymph Node Transplantation, or other microsurgical interventions) can effectively treat HPV-linked cancers while reducing side effects like difficulty swallowing and dry mouth. The trial includes two groups: one receiving standard radiation treatment and the other with reduced or no radiation, depending on the cancer's spread. Suitable candidates have HPV-related neck cancer, have undergone surgery to remove certain tissues, and show no signs of the main tumor. As a Phase 2 trial, this research focuses on measuring the treatment's effectiveness in an initial, smaller group, offering a chance to contribute to advancements in cancer care.
Will I have to stop taking my current medications?
The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.
Is there any evidence suggesting that this trial's treatments are likely to be safe?
Research has shown that intensity-modulated radiotherapy (IMRT) is usually well-tolerated and effectively controls tumors. Studies indicate it causes fewer long-term side effects compared to older radiation methods. However, some patients may experience difficulty swallowing long after treatment.
Current data suggest that surgery can effectively treat certain types of cancer and often improves the quality of life for patients with lymphedema, a condition that can occur after cancer treatments. While this information pertains to a different condition, it provides insight into the safety of surgery.
Since this trial is in Phase 2, researchers have some evidence that these treatments are safe for humans, but they continue to gather more data to confirm this.12345Why are researchers excited about this trial's treatments?
Researchers are excited about this trial because it explores a new approach to treating head and neck cancer by adjusting the use of Intensity-Modulated Radiation Therapy (IMRT). Unlike the standard treatment, which involves radiotherapy to both the neck and mucosal surfaces, this trial tests whether omitting IMRT to the risk mucosa—but still using it conditionally on the neck when needed—can be just as effective. This could potentially reduce side effects associated with radiation to sensitive areas, leading to a better quality of life for patients. The trial aims to find out if this tailored use of IMRT can effectively control cancer while minimizing unnecessary exposure to radiation.
What evidence suggests that this trial's treatments could be effective for head and neck cancer?
Research has shown that head and neck cancers caused by HPV have a high survival rate, with about 90% of patients living at least five years. This finding is encouraging for treating cancers in the lymph nodes when the main tumor is difficult to locate. New imaging techniques and specialized surgeries can now identify these tumors in 70-80% of cases. For patients with small, hidden tumors, surgery alone might suffice, but further research is needed. In this trial, one arm involves surgical intervention, while another includes Intensity-Modulated Radiotherapy (IMRT) to control tumors. IMRT has improved survival rates in many head and neck cancer cases, with studies showing positive results. Both treatments are being studied in this trial to find the best balance between effectiveness and reducing side effects.678910

Are You a Good Fit for This Trial?
This trial is for people with certain head and neck cancers where the primary tumor can't be found, often linked to HPV. Participants should have cancer in their lymph nodes but no detectable primary tumor after advanced imaging and specialized surgeries.Inclusion Criteria
Exclusion Criteria
Timeline for a Trial Participant
Screening
Participants are screened for eligibility to participate in the trial
Surgery
Participants undergo neck dissection, tonsillectomy, and tongue base mucosectomy to locate and treat the primary tumour
Radiation
Radiotherapy is administered to the neck, with conditional omission of mucosal radiation based on trial arm
Follow-up
Participants are monitored for safety, effectiveness, and quality of life post-treatment
What Are the Treatments Tested in This Trial?
Interventions
- Intensity Modulated Radiotherapy (IMRT) to Ipsilateral Neck
- Intensity Modulated Radiotherapy (IMRT) to Mucosa at Risk
- Surgical Intervention
Trial Overview
The SUPERIOR trial is testing if less radiation or just surgery alone can treat these cancers effectively. It compares traditional treatments like full-throat radiation and node removal surgery against reduced radiation areas or possibly surgery only.
How Is the Trial Designed?
2
Treatment groups
Experimental Treatment
Active Control
* If N1 with single node \<= 3cm, no further treatment * If multiple ipsilateral nodes or single ipsilateral node \>3 cm, radiation to Neck only
Radiotherapy to Ipsilateral Neck and to risk Mucosa There are two possible dose levels: * 60 Gy in 30 fractions over 6 weeks (CTV60) o This applies to the dissected levels of the neck * 54 Gy in 30 fractions over 6 weeks (CTV54) * This applies to the mucosal surfaces. Patients randomized to Arm 2 will not have the mucosal surfaces treated
Surgical Intervention is already approved in European Union, United States, Canada, Switzerland for the following indications:
