Radiotherapy for Head and Neck Cancer
(HN-Bio 02 Trial)
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial explores how radiation therapy affects certain biological markers in people with newly diagnosed head and neck cancer. The researchers compare two radiation delivery methods: one with a single integrated boost and another with a two-phase treatment. They aim to improve understanding of how these treatments influence the cancer and its environment. This trial suits individuals with head and neck squamous cell carcinoma, particularly if the primary or nodal disease exceeds 3 cm and they are planned for curative treatment. Participants should be able to undergo MRI scans and remain comfortable lying on their back for an hour. As an unphased trial, this study offers a unique opportunity to contribute to groundbreaking research that could shape future treatment strategies.
Do I have to stop taking my current medications for the trial?
The trial information does not specify whether you need to stop taking your current medications. Please consult with the trial coordinators for more details.
Is there any evidence suggesting that this trial's treatments are likely to be safe?
Previous studies have shown that both types of radiotherapy used in this trial are generally safe. Research indicates that single integrated boost radiotherapy is well-tolerated, even when combined with other treatments. Although some patients may experience long-term side effects, it remains a viable option for those unable to undergo more intense treatments.
The two-phase radiotherapy approach has also proven effective and safe. One study showed it provided good cancer control in the treated area for most patients. While side effects can occur, they are often manageable.
Both treatments are standard practices, commonly used and trusted in treating head and neck cancer. Overall, evidence suggests these radiotherapy treatments are safe for patients.12345Why are researchers excited about this trial?
Researchers are excited about these radiotherapy techniques for head and neck cancer because they offer flexibility and precision in targeting tumors. The Integrated Boost Radiotherapy approach delivers a high dose of radiation to the tumor while simultaneously treating surrounding areas, potentially enhancing effectiveness and minimizing damage to healthy tissue. The Two Phase Radiotherapy method introduces a delayed treatment to the nodal regions, which might help in better managing cancer spread with fewer side effects. Both methods aim to refine current radiotherapy practices, potentially leading to improved patient outcomes.
What evidence suggests that this trial's radiotherapy treatments could be effective for head and neck cancer?
Research has shown that external beam radiotherapy effectively treats head and neck squamous cell carcinoma (HNSCC). In this trial, participants will receive one of two treatment methods: a single integrated boost or a two-phase approach. Studies indicate that the single integrated boost method can achieve response rates of 70–90%. This method precisely targets cancer cells while protecting healthy tissues. Meanwhile, the two-phase treatment demonstrated excellent local control in 97% of patients. Both methods hold significant potential to improve survival and manage the tumor, making them reliable options for treating HNSCC.14678

Exclusion Criteria
Timeline for a Trial Participant
Screening
Participants are screened for eligibility to participate in the trial
Baseline Assessment
Participants undergo a baseline fMRI scan and biopsy of the primary tumor and/or lymph node

What Are the Treatments Tested in This Trial?
Interventions
- Standard of care external beam radiotherapy (single integrated boost)
- Standard of care external beam radiotherapy (two-phase treatment)
Trial Overview
The study explores how standard external beam radiotherapy affects biomarker development in HNSCC patients. It compares two methods: a single integrated boost versus a two-phase treatment approach.
How Is the Trial Designed?
2
Treatment groups
Active Control
External beam radiotherapy 70Gy in 35 fractions to head and neck tumour and 56 Gy in 35 fraction to elective nodal regions. This will be given as single integrated boost or two-phase treatment at clinician discretion.
Standard of care external beam radiotherapy 70 Gy in 35 fractions to head and neck with delayed 40 Gy in 20 fractions to elective nodal regions. This will be given as reversed two-phase treatment.
