Study summary

This phase II trial studies how well personalized neck radiation therapy directed by sentinel lymph node biopsy (SLNB) works in treating patients with oral cavity squamous cell carcinoma (OCSCC). SLNB can be performed as part of standard care for OCSCC. During SLNB, a radiotracer is injected around the tumor. The lymph nodes are then biopsied and tested to see if the tracer injected into the tumor traveled to and is present in the sentinel lymph nodes (SLNs). Results of the SLNB are used to determine whether lymph nodes should be removed in both sides of the neck or just on the same side as the primary tumor. Standard treatment then involves radiation therapy to both sides of the neck, regardless of SLNB results. Radiation therapy uses high energy x-rays, particles, or radioactive seeds to kill tumor cells and shrink tumors. Studies have shown only a small number of patients develop a return of the cancer (recurrence) in the opposite side of the neck after radiation therapy. In addition, radiation therapy can negatively impact patient outcomes like saliva production, speech and swallow function, increased risk of radiation induced cancers, and chronic pain. Standard of care SLNBs may be effective in determining whether radiation therapy only needs to be administered to one side of the neck or both sides. This may help spare tissue on the opposite side of the neck from receiving radiation if there is no indication of lymph node involvement there.

Terms in these criteria, in plain language(9)

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.

Biopsy and archival tissue

A biopsy takes a small piece of tissue to examine. “Archival tissue” is a sample already taken, for example at diagnosis, and kept by the hospital.

Whether a stored sample will do depends on when it was taken, how much there is and what the study needs. Ask whether the study accepts your stored sample or needs a new biopsy.

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.

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.

Childbearing potential

Able to become pregnant: from the first period until menopause, unless permanently unable to through surgery (removal of the womb, or of both ovaries or both fallopian tubes).

Criteria for people of childbearing potential usually ask for a negative pregnancy test and for contraception during the study and for a time after it.

Contraception

Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.

Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.

Metastases

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

Cancer (malignancy)

Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.

Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.

Immunosuppression

A weakened immune system. It can come from an illness, such as HIV or some blood cancers, or from medicines that turn the immune system down, for example after an organ transplant or for an autoimmune disease; steroids at higher doses count.

Read whether the line is about a condition or about medicines, and which medicines and doses it means.

Investigational drug or device

A drug or device being studied in a clinical trial.

It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.

What researchers measure

Primary outcomes

  1. Contralateral regional control rate

    Contralateral regional control rate is defined as the proportion of evaluable subjects free of contralateral neck recurrence at 1 year from completion of definitive treatment. Regional Recurrence is defined as biopsy-proven cancer within the ipsilateral or contralateral neck at any time point after initial surgical resection. When biopsy is not feasible, evidence of recurrence by imaging suffices only with documented attestation at tumor board that the imaging is clinically diagnostic of regional recurrence. Cumulative incidence function estimate with 90% confidence interval (CI) for follow-up after 1 year.

    Time frame: From completion of definitive treatment to neck recurrence date, death date or date of last contact, assessed at 1 year from completion of definitive treatment

Secondary outcomes

  1. Change in neck function

    Will be assessed using five number summary\* (minimum \[min\], first quartile \[Q1\], median, third quartile \[Q3\], maximum \[max\]) of Neck Dissection Impairment Index summary scores.

    Time frame: Baseline up to 1 year from completion of definitive treatment

  2. Change in oral and oropharyngeal dryness

    Will be assessed using five number summary\* (min, Q1, median, Q3, max) of summary score on the Xerostomia questionnaire.

    Time frame: Baseline up to 3 months from completion of definitive treatment

  3. Change in quality of life

    Will be assessed using five number summary\* (min, Q1, median, Q3, max) of summary score on the University of Washington Quality of Life Survey, a 15-item survey evaluating quality of life metrics focused on speech, eating, saliva, taste, phlegm, employment, recreation, activity, disfigurement, and pain.

    Time frame: Baseline up to 3 months from completion of definitive treatment

  4. Recurrence free survival

    Will assess # evaluable, # events and # censored at 1 year from completion of definitive treatment, as well as Kaplan-Meier (KM) estimate with 95% CI.

    Time frame: 1 year from completion of definitive treatment

  5. Overall survival

    Will assess # evaluable, # events and # censored at 1 year from completion of definitive treatment, as well as KM estimate with 95% CI.

    Time frame: 1 year from completion of definitive treatment

  6. Disease-specific survival

    Will assess # evaluable, # events and # censored at 1 year from completion of definitive treatment, as well as KM estimate with 95% CI.

    Time frame: 1 year from completion of definitive treatment

Started Jul 2025 (actual). Primary completion is estimated for Jul 2030, 59 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 59 months is close to that.

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

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 Jul 31, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
