Clinical Trial Summary

This is a non-randomized, open-label phase II clinical trial that studies the effect of reduced dose radiation therapy and chemotherapy after surgery in treating patients with human papillomavirus (HPV) caused throat cancer. Giving reduced dose radiation therapy and chemotherapy after surgery may improve quality of life compared with standard of care primary chemoradiation approach without compromising survival.

Description:

PRIMARY OBJECTIVE: I. To measure swallowing function and disease specific quality of life of patients with oropharyngeal cancer treated with transoral surgery and reduced intensity adjuvant therapy. SECONDARY OBJECTIVES: I. To examine kinetics of circulating tumor deoxyribonucleic acid (DNA) in patients treated with transoral surgery. II. To estimate local control, progression free and overall survival using transoral surgery and reduced intensity adjuvant therapy. OUTLINE: Based on pathologic findings after standard of care transoral surgery, patients are assigned to 1 of 3 groups. GROUP I (LOW RISK): Patients whose small tumor was removed completely and have only one lymph node involved will undergo clinical observation. GROUP II (MEDIUM RISK): Patients whose tumor was removed completely but has certain features that make it more likely to come back such as growth around the nerves or into the vessels, or has more than one lymph nodes involved, will undergo external body radiation therapy (EBRT) for 5 weeks in the absence of disease progression or unacceptable toxicity. GROUP III (HIGH RISK): Patients whose tumor has a "positive margin", which means the tumor could not be removed with healthy tissue around it or tumor grows significantly outside the lymph node will undergo EBRT for 6 weeks and receive cisplatin intravenously (IV) weekly for 6 weeks in the absence of disease progression or unacceptable toxicity. After completion of study treatment, patients are followed up for 3 years.

Intervention

Procedure:
• Transoral Surgery
Patients will undergo transoral surgery

Radiation:
• External Beam Radiation Therapy
Patients in Group II and Group III will undergo External Beam Radiation Therapy (EBRT) RT following transoral surgery.

Drug:
• Cisplatin
Patients in Group III will receive cisplatin, 30 mg/m2, administered intravenously weekly per for 6 weeks.

Procedure:
• Incisional Tumor Biopsy
Incisional biopsy of the primary tumor site will be required to confirm p16/HPV status of the tumor

Other:
• Circulating tumor deoxyribonucleic acid (ctDNA) levels assessment
Assess ctDNA levels at baseline, 2 weeks, 4 weeks, 10 weeks, 24 weeks and 1 year after the surgery.
• MD Anderson Dysphagia Index
MDADI is a 20 item quality of life questionnaire specifically focusing on swallowing aspects. It was originally designed for head and neck cancer patients. The total score ranges from 20 to 100 with the higher score indicating higher level of function.
• University of Washington Quality of Life Questionnaire
University of Washington Questionnaire is a 15 item quality of life instrument specifically designed for head and neck cancer patients.
• Euro-QOL 5 dimension scale questionnaire
A generic quality of life and cost utility instrument widely used and validated for multiple disease settings, including head and neck cancer.

Diagnostic Test:
• Modified barium swallow (MBS) evaluation with aspiration-penetration scale
The videofluoroscopic modified barium swallow (MBS) study is the gold standard for for the evaluation of dysphagia, and specifically, airway protective mechanisms. The penetration/aspiration (PEN/ASP) scale is a routinely used eight-point scale designed to describe the depth of bolus penetration into the airway and the patient response to the penetration or aspiration.
