A Phase 2 interventional study of therapeutic conventional surgery and laboratory biomarker analysis in Oropharynx Cancer, sponsored by Heath Skinner. Recruiting at 1 site in United States. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2026-07-21.
Sponsored by Heath Skinner · Phase 2, Interventional, and Treatment
This is a trial studying patients with human papilloma virus (HPV) positive oropharyngeal cancer with tumors that can be removed via transoral surgery. Following surgery, patients will be classified as either low, intermediate, or high risk based on the characteristics of the tumors. Low risk patients (Arm S) will receive no further treatment after surgery. Intermediate risk patients (Arm RT) will be treated with Intensity Modulated Radiotherapy (IMRT) after surgery. High risk patients (Arm CRT) will receive a combination of IMRT and chemotherapy after surgery. Patients will be followed for up to five years after the completion of treatment.
This phase II trial is designed to rationally de-escalate adjuvant (Intensity Modulated Radiotherapy (IMRT) in the post-transoral surgery (TOS) setting in a study population consisting of patients with resectable oropharynx carcinoma, p16+ as confirmed by immunohistochemistry IHC, with a performance status (PS) of 0-1. Patients will be classified into one of three category/treatment groups (low-, intermediate-, and high-risk) according to their highest pathologically risk feature. Radiation will be given via an IMRT technique. For the high-risk patient group, a reduced, but slightly accelerated radiotherapy (RT) fractionation regimen of 50 Gy (HCC 18-034) in conjunction with cisplatin will be used compared to the standard 66 Gy and cisplatin. Low risk patients will transition to observation, intermediate risk patients will receive 30 Gy in 15 fractions of IMRT, and high risk patients will receive 50 Gy in 25 fractions (one day a week will include two treatments) plus 40 mg/m2 Cisplatin for 5 weeks. Patients who are not able to tolerate cisplatin will receive carboplatin instead.

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.
Patients must be deemed eligible for a TOS procedure with no evidence of distant metastasis as determined by imaging studies. Metastatic disease may be evaluated using CT or PET/CT where appropriate; this can be performed with or without contrast. The following imaging is acceptable to evaluate the primary and regional disease:
Patients with the following within the last 6 months prior to registration must be evaluated by a cardiologist and/or neurologist prior to entry into the study.
Patients must have acceptable renal and hepatic function within 4 weeks prior to registration
o For patients stratified following surgery and to concurrent chemotherapy (Arm CRT), calculated must be > 60 ml/min using the Cockcroft-Gault formula
Exclusion Criteria:
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.
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.
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.
A 0–100 scale of how well someone can carry out everyday activities. 100 is no complaints and no signs of illness; 70 is able to look after yourself but not to work or keep up normal activity; 50 is needing considerable help and frequent medical care.
Studies often ask for 60 or 70 and above. Your doctor gives the score.
Neoadjuvant treatment is given before the main treatment (usually surgery), often to shrink a tumour. Adjuvant treatment is given after it, to lower the chance of the cancer coming back.
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.
Cancer that has spread from where it began to other parts of the body. “Metastatic” cancer is cancer that has spread this way.
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.
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.
The New York Heart Association’s four classes of how much heart failure limits physical activity.
Studies set their own limit — many outside heart failure leave out class III–IV, while heart failure studies may ask for a particular class. Check the class this study names.
A “mini-stroke”: temporary stroke-like symptoms caused by reduced blood flow to part of the brain, spinal cord or eye, without signs of a new stroke on a scan.
Stroke symptoms need emergency care at once, even if they go away.
How quickly the kidneys clear creatinine, a waste product, from the blood. A study may estimate it from a blood test with age, weight and sex (often by the Cockcroft–Gault formula), or measure it using blood and urine collected over a set time. Given in mL/min; higher is better.
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.
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.
Periods have stopped for good: usually no period for 12 months in a row without another medical reason, sometimes confirmed by a blood test (FSH).

Recurrence-Free Survival (RFS)
Time to recurrence, defined as local and/or regional progression (identification of disease growth that is present within the area in which it was first located) and/or distant metastasis (identification of disease growth that is present in area(s) distant to that previously located). Local progression is defined as progression at the primary tumor site. Regional progression is defined as progression in the draining lymphatics (typically the cervical, retropharyngeal/retrostyloid and supraclavicular lymph nodes). Distant progression is defined as tumor recurrence in one or more non-local and non-regional sites (e.g., bone, lung, liver, etc.). Recurrent malignancy will be determined based on clinical exam and imaging findings. Patients who are disease-free but who die from other causes will be censored.
Time frame: Up to 2 years (for cohort)
Loco-regional control (at 1 year)
Loco-regional control will be evaluated based on the percentage of patients without recurrence (identification of disease growth) in the primary site or regional lymphatics based on imaging and/or clinical exam.

Time frame: Up to 5 years
Quality of Life via FACT-HN
FACT-HN is a self-administered questionnaire. Item responses are on a Likert scale score ranging from 0 to 4. Individual responses are summed to compute subscale scores, and the subscales to compute overall total scores. FACT-HN includes 2 parts - FACT-G and FACT-HN. The basic FACT-G (general) is comprised of 27 items, with four subscales including Physical Well-Being (score = 0-28), Social/Family Well-Being (score= 0-28), Emotional Well-Being (score = 0-24), and Functional Well-Being, (score = 0-28), for a total score min/max = 0-108. The FACT-HN is comprised of 12 head and neck specific items (0-48). Thus, the overall total possible score range is 0-156. Analysis will include the FACT Head \& Neck Trial Outcome Index, a composite score which includes only physical, functional, and FACT-HN, thus, scores range from 0-104. Higher scores indicate better Quality of Life.
Time frame: Baseline (before treatment), at 4-8 weeks post-surgery, at 3 months, 6 months, 1 year, up to 2 years following treatment
MD Anderson Symptom Inventory-Head & Neck (MDASI-HN)
Patient-reported swallowing perception and performance using MDASI-HN measures treatment related symptom burden in head and neck cancer patients. The 20-item MDASI measures both severity and burden of symptoms and their effect on patients' daily activities, using a numeric rating scale of 0-10. This instrument includes 13 core symptoms and 9 head and neck specific items. Higher scores indicate superior perception of function.
Time frame: Baseline (before treatment), at 4-8 weeks post-surgery, at 3 months, 6 months, up to 2 years following treatment
Modified Barium Swallow (MBS) rating
Three swallowing outcomes will be rated by the SLP conducting the MBS study and reported by research staff: 1) laryngeal penetration (yes, no); 2) aspiration (no, sensate, silent), and 3) pharyngeal residue (no, \< 50%, \> 50%). These have been selected as universal items generally reported by swallowing clinicians that have been shown to significantly predict pneumonia in patients with oropharyngeal cancers. Prevalence of these dysphagia endpoints will be estimated at each time point.
Time frame: Before treatment, at 4-8 weeks post-surgery, 6 months and 24 months following treatment
Voice outcomes
Patient-reported voice outcomes will be assessed using the Voice Handicap Index-10 (VHI-10) survey. The VHI-10 is a patient self-assessment instrument that quantifies patients' perception of their voice handicap. It evaluates patient's physical (P), emotional (E), and functional (F) perceptions of voice and has shown to be highly reliable for internal consistency and test-retest stability. The VHI-10 utilizes a 10-item questionnaire in which the patient circles the response that most accurately reflects his or her own experience on a linear scale (from "never" to "always"). "Always" response is scored 4 points, a "Never" response is scored 0. The remaining options are scored between 1 and 3 points. The tallied number of points for each of the subscales is computed to a total composite score. The patient's values are compared to published norms.
Time frame: Baseline (before treatment), at 4-8 weeks post-surgery, at 1 year, up to 2 years following treatment
Performance Status Scale (PSS-HN)
The Performance Status Scale (PSS-HN) is a clinician-rated instrument consisting of 3 questions: normalcy of diet, public eating/swallowing, and understandability of speech subscales in patients with head and neck cancer. Each subscale is rated from 0 to 100, with higher scores indicating better performance.
Time frame: Baseline (before treatment), at 4-8 weeks post-surgery, at 3 months, 6 months, 1 year, up to 2 years following treatment
MD Anderson Dysphagia Inventory (MDADI)
Patient-reported swallowing-related quality of life will be measured using the MD Anderson Dysphagia Inventory (MDADI). It evaluates the patient's physical (P), emotional (E) and functional (F) perceptions of swallowing dysfunction. The MDADI is a 20-item questionnaire in which the patient circles the response that best reflects their experience in the past week on a 5-point Likert Scale with answers ranging from "Strongly Agree" (scored as 1 point on all questions except E7 and F2, where it is scored as 5 points) to "Strongly Disagree" (scored as 5 points on all questions except E7 and F2, where it is scored as 1 point). Scores for individual questions are summed and averaged to obtain a composite score ranging from 20 (extremely low swallow functioning) to 100 (high swallow functioning).
Time frame: Baseline (before treatment), at 4-8 weeks post-surgery, at 1 year, up to 2 years following treatment
