About this study
Official title: A Phase II Investigation of Lymphoscintigraphy Directed Elective Neck Radiation for p16+ Favorable Risk Oropharynx Cancer Patients Managed With Primary (Chemo) Radiation
This is a prospective, phase II, stratified single arm investigation for favorable prognosis in p16+ oropharynx cancer patients with either node negative or malignant neck adenopathy with lymphoscintigraphy mapping confined to the ipsilateral neck.
Read the detailed description
This is a prospective, phase II, stratified single arm investigation for favorable prognosis in p16+ oropharynx cancer patients with either node negative or malignant neck adenopathy with lymphoscintigraphy mapping confined to the ipsilateral neck. Patients positive for p16 status will be approached for consent during the pre-treatment intake process. Contralateral neck progression will be measured by PET (positron emission tomography)/CT scans. Xerostomia will be measured by the EORTC QLQ (European Organization for the Research and Treatment of Cancer Quality of Life Questionnaire) H\&N35 at 6, 12, and 24 months. Patients will remain on study treatment for 6-7 weeks or until unacceptable toxicity or withdrawal of consent. Disease free survival (DFS) and overall survival (OS) will be assessed until 24 months after completion of study treatment
- Conditions
- Oropharynx Cancer
- Being tested
- Radiation therapy (5 days for 7 weeks), Radiation therapy (5 days for 6 weeks), Cisplatin
- Medical subject headings
- Oropharyngeal Neoplasms
What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Radiation therapy (5 days for 7 weeks)Radiation
Mon-Fri (5 days for 7 weeks), total 35 fractions over 35 treatment days of radiation therapy (RT)
Radiation therapy (5 days for 6 weeks)Radiation
Mon-Fri (5 days for 6 weeks), total 35 fractions over 30 treatment days of RT (two doses 6 hours apart except for the last 6th Friday of the 6 weeks )
CisplatinDrug
Cisplatin, 40mg/m2 (weekly for 7 weeks)
| Study group | Role | What they receive |
|---|---|---|
| Cohort A (>N1 or single node > 3cm ) | Experimental | More extensive neck involvement or proximity to the midline can qualify a patient in cohort A. Cohort A will have patients with either more than one lymph node adenopathy or 1 lymph node that is large (>3cm). Receives: Radiation: Radiation therapy (5 days for 7 weeks); Drug: Cisplatin |
| Cohort B (N0 or N1 <3cm) | Experimental | For Cohort B patients need to have either no lymph nodes or only one lymph node adenopathy, provided it is smaller than 3cm. Receives: Radiation: Radiation therapy (5 days for 6 weeks) |
What is being measured
The primary outcome is the main question the study is designed to answer.
Number of patients that develop cancer on the contra-lateral side of the neck within 12 months of completion of radiation treatment
To evaluate the development of cancer on the contra-lateral side of the neck within 12 months of completion of radiation treatment.
Measured: 1 year
Secondary outcomes (7)
Level of xerostomia
To evaluate whether the omission of elective radiation to the contralateral neck decrease patient reported xerostomia at 6, 12, and 24 months to a mean score of 47.2 (from an expected 57.2) as measured by the European Organization for Research and Treatment of Cancer (EORTC) QLQ H\&N35
Measured: 2 years
Mean swallowing change (modified barium swallowing test)
To evaluate the functional swallowing change of patients treated with unilateral neck radiation as measured by a modified barium swallow for the period of one year after the end of radiotherapy. The investigators will use summary statistics such as changes in means and changes in proportions to evaluate the functional swallowing change of patients treated with unilateral neck radiation as measured by a modified barium swallow test.
Measured: 2 years
Mean swallowing change (patient reported)
To evaluate patient reported swallowing of patients treated with unilateral neck radiation as measured by the EORTC QLQ H\&N 35 for the period of two years after the end of radiotherapy. The investigators will use summary statistics to characterize changes in means of reported swallowing for patients treated with unilateral neck radiation as measured by the EORTC QLQ H\&N 35. The investigators will use sign-rank tests to investigate if the changes are equal to zero.
Measured: 2 years
Rate of contralateral neck progression
To evaluate the development of cancer on the contra-lateral side of the neck within 24 months of completion of radiation treatment. The investigators will use cumulative incidence curves and Fine and Gray proportional hazards regressions to characterize the rate of contralateral neck progression for the period of 2 years after the completion of radiation. In this analysis, death will be considered a competing risk.
Measured: 2 years
Overall survival (OS)
To evaluate the OS of head and neck cancer patients treated with unilateral neck radiation for the period of two years after the end of radiotherapy using Kaplan Meier curves and Cox proportional hazards regressions.
Measured: 2 years
Disease free survival (DFS)
To evaluate the DFS in accordance with RECIST 1.1 of head and neck cancer patients treated with unilateral neck radiation for the period of two years after the end of radiotherapy using Kaplan Meier curves and Cox proportional hazards regressions.
Measured: 2 years
Dosimetric degree of normal tissue avoidance
To quantify the dosimetric degree of normal tissue avoidance of unilateral neck radiation when compared to bilateral neck radiation using Wilcoxon Rank-Sum tests
Measured: 2 years

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing Radiation therapy (5 days for 7 weeks), Radiation therapy (5 days for 6 weeks) and Cisplatin in people with Oropharynx Cancer, run by Fox Chase Cancer Center at 1 site in United States.
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 14 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 2 Nov 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
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 Ryan Romasko (2678388380, ryan.romasko@fccc.edu), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Number of patients that develop cancer on the contra-lateral side of the neck within 12 months of completion of radiation treatment (time frame: 1 year). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
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 2 Nov 2026.
