About this trial

About 3% of people with head and neck cancer have cancer in their lymph nodes, but doctors are unable to find the primary tumour. This situation has become more common due to human papillomavirus (HPV), a virus linked to certain cancers. Generally, patients with HPV-related cancers have a good outlook, with around 90% surviving for at least five years.

Recent advancements in medical technology, such as advanced imaging and specialized surgeries, have significantly improved doctors' ability to find these hidden tumours. These techniques can locate the primary tumour in 70-80% of cases. If the tumour remains undetected, it could be very small or potentially eliminated by the body's immune system.

The best way to treat this type of cancer is still debated. Current treatment options include surgery to remove lymph nodes or radiation therapy. There is no clear agreement on which areas should receive radiation. Often, surgery is performed on one side of the throat to try and locate the tumour's origin.

Researchers are exploring ways to minimize the harmful side effects of treatment. Some studies suggest that surgery alone might be sufficient for patients with small tumours in their neck, but more research is needed. Another important question is whether radiation needs to cover the entire throat area. Recent findings suggest that omitting radiation from some areas might reduce side effects such as difficulty swallowing and dry mouth.

The SUPERIOR trial aims to investigate whether reducing the amount of radiation can still be effective and improve patients' quality of life. The study also examines whether surgery alone is adequate for certain patients with HPV-related cancers.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

p16 positive PUK SCC of the neck

Age 18 years or older

Willing to provide informed consent

Eastern Cooperative Oncology Group (ECOG) performance status 0-2

Disqualifiers

Radiological or pathological extra-nodal extension

Epstein-Barr Virus (EBV)-positive

Clinical nodal stage (i.e. before neck dissection) N2-3, AJCC 8th edition (ie. bilateral nodes or node >6cm)

Pathological nodal stage (i.e. after neck dissection) pN3

Trial design

Design model

Parallel

Treatments tested in this trial

  • Intensity Modulated Radiotherapy (IMRT) to Mucosa at Risk

    Radiation

    Patients in Arm 1, after the surgical procedure, will receive radiotherapy to the at-risk mucosa.

  • Surgical Intervention

    Procedure/Surgery

    These patients will undergo Neck dissection, TORS tonsillectomy (unilateral vs bilateral tonsillectomy at the discretion of the treating physician) + ipsilateral tongue base mucosectomy.

  • Intensity Modulated Radiotherapy (IMRT) to Ipsilateral Neck

    Radiation

    For Arm1, after the surgical procedure, the patients will receive radiotherapy to the ipsilateral neck. For Arm2, the patients will only receive IMRT to neck, if multiple ipsilateral nodes or single ipsilateral node \>3 cm is observed

Treatment groups

90 Participants
are divided into 2 treatment groups
Group A: Arm1: Standard of Care TreatmentActive comparator 3 interventions
Group B: Arm 2: Omission of IMRT to Risk Mucosa but conditional IMRT to NeckExperimental treatment 2 interventions

Trial outcomes

Primary outcomes

1

Primary Endpoint: Rate of Primary Emergence of Mucosal p16-Positive Squamous Cell Carcinoma

The primary endpoint of this clinical trial is to assess the rate at which a primary mucosal p16-positive squamous cell carcinoma (SCC) emerges in the upper aerodigestive tract (which includes the oral cavity, pharynx, or larynx) in patients with p16-positive PUK of the head and neck. This rate will be compared to a historical control to determine the impact of omitting mucosal radiation in these patients. The primary objective is to evaluate the oncologic outcomes associated with this treatment approach.

Time frame
2 years

Secondary outcomes

1

MD Anderson Dysphagia Inventory (MDADI)

MD Anderson Dysphagia Inventory (MDADI): Measures the impact of swallowing difficulties on a patient's daily life and emotional well-being. Scale Range: 20 to 100. Interpretation: Higher scores indicate a better outcome, reflecting better swallowing function and less impact on quality of life.

Time frame
Assessed at baseline, 6 months, and 1 year post randomization
2

European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 (EORTC QLQ-C30)

Outcome Measure: General health status and overall quality of life in cancer patients, including physical functioning, role functioning, emotional functioning, and overall health. Scale Range: 0 to 100. Interpretation: Higher scores on functional scales and global health status indicate a better outcome. Higher scores on symptom scales indicate a worse outcome.

Time frame
Time Frame: Assessed at baseline, 6 months, and 1 year post randomization.
3

European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire Head and Neck 35 (EORTC QLQ-H&N35)

Outcome Measure: Head and neck cancer-specific symptoms and issues, particularly related to treatment effects. Scale Range: 0 to 100. Interpretation: Higher scores on symptom scales indicate a worse outcome, reflecting more severe symptoms or problems related to head and neck cancer.

Time frame
Assessed at baseline, 6 months, and 1 year post randomization
4

European Quality of life (Euro-QoL) 5-Dimension 5-Level (EQ-5D-5L): Visual Analog Scale

Outcome Measure: Health-related quality of life across five dimensions: mobility, self-care, usual activities, pain/discomfort, and anxiety/depression. Scale Range: -0.281 to 1 (Index value) and 0 to 100 (Visual Analog Scale). Interpretation: For the Index value, higher scores indicate a better outcome (better health-related quality of life). For the Visual Analog Scale, higher scores indicate better perceived overall health.

Time frame
Assessed at baseline, 6 months, and 1 year post randomization
