About
This phase II trial tests whether reduced dose radiation therapy after transoral robotic surgery works in treating patients with human papillomavirus (HPV)-positive oropharyngeal cancer. HPV positive oropharyngeal cancer has a better prognosis than oropharyngeal cancer not caused by HPV. A standard of care treatment for HPV positive oropharyngeal cancer is transoral robotic surgery followed by radiation therapy. However, this treatment is associated with many long-term side effects including difficulty swallowing. Radiation therapy uses high energy rays to kill tumor cells and shrink tumors. Giving reduced dose radiation therapy after transoral robotic surgery may improve swallowing outcomes and quality of life compared to standard of care dose radiation therapy after transoral robotic surgery.
Full description
PRIMARY OBJECTIVE:
I. To evaluate swallow function among post-operative circulating tumor HPV deoxyribonucleic acid (ctHPVDNA)-negative patients treated with reduced intensity adjuvant radiation therapy (RT) doses as compared to historical controls from ECOG 3311.
SECONDARY OBJECTIVES:
I. Evaluate progression free survival (PFS), overall survival (OS), and locoreginal control (LRC) among post-operative ctHPVDNA-negative patients treated with reduced adjuvant RT doses.
II. Evaluate PFS among post-operative ctHPVDNA-positive patients treated with standard of care adjuvant therapy.
OUTLINE:
Patients who are ctHPVDNA negative after surgery undergo reduced dose radiation therapy for 3 weeks (15 treatments). Patients who are ctHPVDNA positive after surgery undergo standard of care radiation therapy.
After completion of study treatment, patients are followed up at 3, 6, 12, 18, and 24 months.

Inclusion criteria
Age >= 18 years.
Eastern Cooperative Oncology Group (ECOG) performance status =< 2 (Karnofsky >= 60%).
Life expectancy > 12 weeks as determined by the Investigator.
Has diagnosis of HPV-associated squamous cell carcinoma of the oropharynx
pT1-2, pN0-1, cM0 disease.
Positive ctHPVDNA titer prior to surgery.
=< 10 pack-year smoking history.
Completed transoral robotic surgery (TORS) oropharyngectomy and at least ipsilateral neck dissection by an Emory otolaryngologist.
Pathology must demonstrate at least one of the follow intermediate risk factors:
Pathology cannot demonstrate > 4 positive lymph nodes, ENE, or a positive final margin (defined as < 1 mm). Margins that have been subsequently cleared are allowed.
Radiation increases the risk of birth defects. For this reason, females of child-bearing potential (FCBP) must have a negative serum or urine pregnancy test prior to starting therapy.
FCBP and men must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry and for the duration of study participation. Should a woman become pregnant or suspect she is pregnant while she or her partner is participating in this study, she should inform her treating physician immediately. Men treated or enrolled on this protocol must also agree to use adequate contraception prior to the study, for the duration of study participation, and 12 months after completion of radiation. A female of childbearing potential is a sexually mature woman who: 1) has not undergone a hysterectomy or bilateral oophorectomy; or 2) has not been naturally postmenopausal for at least 24 consecutive months (i.e., has had menses at any time in the preceding 24 consecutive months.
Willingness and ability of the subject to comply with scheduled visits, drug administration plan, protocol-specified laboratory tests, other study procedures, and study restrictions.
Evidence of a personally signed informed consent indicating that the subject is aware of the neoplastic nature of the disease and has been informed of the procedures to be followed, the experimental nature of the therapy, alternatives, potential risks and discomforts, potential benefits, and other pertinent aspects of study participation.
