Radiotherapy vs. Trans-Oral Surgery for HPV-Negative Oropharyngeal Squamous Cell Carcinoma

A Phase 2 interventional study of Radiation and Trans-Oral Surgery (TOS) + Neck Dissection in Head and Neck Cancer and Oropharyngeal Squamous Cell Carcinoma, sponsored by London Health Sciences Centre Research Institute and Lawson Research Institute of St. Joseph's. Recruiting at 1 site in Canada. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2020-09-04.

  1. The study's listed conditions name Squamous Cell Carcinoma of Head and Neck, a narrower term within Head and Neck Neoplasms.
Confidence
High: the new condition is named in the study's own listed conditions. Of 351 hand-checked studies reclassified this way, 68% were exactly right and 84% in the right disease family; the registry's first term was right for 5% (measured 2026-10-21). How we classify →

Study summary

The goal of this randomized phase II study is a formal comparison of radiotherapy versus trans-oral surgery as the primary treatment of HPV-negative patients with early-stage oropharyngeal carcinoma.

Read the detailed description

This study is designed as a randomized phase II study. Patients will be randomized between current standard of care treatment (Arm 1) vs. TOS (Arm 2) in a 1:1 ratio. Additionally, patients will be stratified according to T stage (T1 vs. T2); N stage (N0/1 vs. N2/3)

The randomized phase II design is required for three reasons:

  1. The randomization will provide an appropriate control group to serve as a comparator for the experimental arm. Historical or contemporaneous non-randomized controls would not be appropriate due to the multitude of biases that could be introduced by patient selection and other confounders.
  2. A small sample size will allow for adequate power to assess for progression-free survival, and also an assessment of quality of life, overall survival and toxicity.
  3. The results will allow for a decision as to whether a multi-institutional phase III trial is warranted, and inform the design of such a trial.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Age 18 years or older
  • Willing to provide
  • performance status 0-2
  • confirmed squamous cell carcinoma
  • HPV-negative tumor, as determined by: negative p16 status, real time PCR or in-situ hybridization. Central confirmation is not required prior to randomization. Equivocal/uncertain HPV status will be allowed on trial.
  • Primary tumor site in the oropharynx (includes tonsil, soft palate, base of tongue, walls of oropharynx)
  • Tumor stage: T1 or T2, with likely negative resection margins at surgery
  • Nodal stage: N0-3. Patients with positive nodal disease and extranodal extension on imaging may be included at the surgeon's discretion, if the nodal disease is deemed resectable by the operating surgeon.
  • Eligible for curative intent treatment, with likely negative resection margins at surgery. For patients where adequate transoral access is in question, they will first undergo an examination under anesthesia prior to randomization to ensure adequate exposure can be obtained.
  • Blood work obtained within 4 weeks prior to randomization, with adequate bone marrow function, hepatic, and renal function, as determined by the investigator.
  • Patient assessed by a radiation oncologist and surgeon and presented at multidisciplinary tumor board prior to randomization. If not feasible, case can be discussed with study Principal Investigator.

Exclusion criteria

Exclusion Criteria:

  • Serious medical comorbidities or other to radiotherapy, chemotherapy or surgery
  • Prior history of head and neck cancer within 5 years
  • Prior head and neck radiation at any time
  • disease
  • Inability to attend full course of radiotherapy or follow-up visits
  • Prior invasive malignant disease unless disease-free for at least 5 years or more, with the exception of non-melanoma skin cancer
  • Unable or unwilling to complete QOL questionnaires
  • Pregnant or lactating women
Terms in these criteria, in plain language(5)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

ECOG performance status

A scale of how much an illness limits everyday activity. For people being assessed to join a study, scores run from 0 (fully active) to 4; lower is more active.

0
Fully active, no restrictions.
1
Limited in strenuous activity, but walking and able to do light work, such as housework or office work.
2
Walking and able to look after yourself, but unable to work; up and about more than half of waking hours.
3
Able to look after yourself only in part; in bed or a chair more than half of waking hours.
4
Unable to look after yourself at all; in bed or a chair all day.

Studies most often ask for 0–1 or 0–2. Your doctor gives the score; the WHO scale uses the same steps. The full scale also has 5, which records death.

Histologically or cytologically confirmed

The diagnosis was confirmed by looking at a sample under a microscope: tissue from a biopsy or surgery (histology), or cells from a fluid or needle sample (cytology).

Your pathology report is the document that shows this.

Contraindication

A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.

Metastases

Cancer that has spread from where it began to other parts of the body. “Metastatic” cancer is cancer that has spread this way.

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Started Jun 2020 (actual). Primary completion is estimated for Feb 2028, 92 months after the start.

Of 298 non-industry phase 2 interventional studies under Squamous Cell Carcinoma of Head and Neck, half reached primary completion within 56 months of starting (the median), counting those still running; a quarter within 37 and three quarters within 85. This study's planned 92 months is above that.

Counting every sponsor, half of 366 studies reached it within 53 months; a quarter within 35 and three quarters within 82.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Sep 4, 2020, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
