About this study
Official title: SPECT-CT Guided ELEctive Contralateral Neck Treatment for Patients With Lateralized Oropharyngeal Cancer. A Phase III Randomized Controlled Trial
This study is being done to answer the following question:
Is the chance of cancer spreading or returning the same if radiotherapy to the neck is guided, by using a special imaging study called lymph node mapping (lymphatic mapping) Single Photon Emission Computed Tomography (SPECT-CT), compared to the usual treatment when radiotherapy is given to both sides of the neck?
Read the detailed description
This study is being conducted in order to find out if this approach is as good as the usual approach in controlling the cancer and has fewer side effects and better quality of life. The usual approach for patients who are not in a study is treatment which includes radiotherapy to the tumour and to both sides of the neck to decrease the risk of spread or recurrence of the cancer
- Conditions
- Oropharyngeal Cancer
- Being tested
- Lymphatic Mapping with SPECT-CT, Ipsilateral and Contralateral Neck

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing Lymphatic Mapping with SPECT-CT and Ipsilateral and Contralateral Neck in people with Oropharyngeal Cancer, run by Canadian Cancer Trials Group at 38 sites in 2 countries.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 18 inclusion and 11 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: looking for participants now, as of the sponsor's last update on 14 Jul 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 38 sites in United States, Canada. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Wendy Parulekar (613-533-6430, wparulekar@ctg.queensu.ca), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Disease-free Survival (time frame: 8 years). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT05451004, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 14 Jul 2026.
