Current Primary Outcome Measures (submitted: July 21, 2014)

• PFS rate [ Time Frame: Up to 2 years ]
  Defined as the proportion of patients alive and progression-free at 24 months. Kaplan-Meier estimates will be calculated. 90% exact binomial confidence intervals will be computed for each arm. The 2-year failure proportions that include second primary cancers from the head and neck region as event will also be reported.
• Accrual rate [ Time Frame: Up to 18 months ]
• Risk distribution [ Time Frame: Up to 18 months ]
  A 90% binomial confidence interval will be estimated for the percentage of patients in each risk group.
• Incidence of grade 3-4 bleeding events during surgery and positive margins after surgery, graded according to the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE) version 4.0 [ Time Frame: Up to 18 months ]
  The percentage will be deemed too high if 13 or more patients reported with grade 3-4 bleeding in the operating room or with positive margins, which corresponds to an empirical rate of 22%. A 90% binomial confidence interval will be estimated for these events.

Current Secondary Outcome Measures (submitted: July 21, 2014)

• Incidence of adverse events evaluated by the CTCAE version 4.0 [ Time Frame: Up to 3 years ]
  The difference between arms will be evaluated using Fisher's exact test.
• Overall survival [ Time Frame: Time from registration onto the study until death from any cause, assessed up to 3 years ]
  Kaplan-Meier estimates will be calculated, along with their corresponding 95% confidence intervals. The median, 1-year, and 2-year survival rates will be estimated.
• Swallowing function before and after treatment, evaluated using the modified barium swallow (MBS) ratings, performance status scale for head and neck cancer (PSS-HN) normalcy of diet scale, and the MD Anderson Dysphagia Inventory (MDADI) [ Time Frame: Up to 2 years ]
  Descriptive statistics will be provided (by arm) for swallowing function, evaluated using the MBS ratings, PSS-HN normalcy of diet scale, and the validated survey MDADI instrument. Longitudinal analysis will be performed, by arm, on each of these measures.
• Voice before and after treatment, evaluated using the Voice Handicap Index-10 [ Time Frame: Up to 2 years ]
  Longitudinal analysis will be performed, by arm, on each of these measures.
• Change in patient reported quality of life (QOL) as measured by Functional Assessment of Cancer Therapy-Head and Neck [ Time Frame: Baseline up to 6 months post radiation therapy ]

Descriptive Information

• Brief Title: Transoral Surgery Followed By Low-Dose or Standard-Dose Radiation Therapy With or Without Chemotherapy in Treating Patients With HPV Positive Stage III-IVA Oropharyngeal Cancer
• Official Title: Phase II Randomized Trial of Transoral Surgical Resection Followed by Low-Dose or Standard-Dose IMRT in Resectable p16+ Locally Advanced Oropharynx Cancer
• Brief Summary: This randomized phase II trial studies how well transoral surgery followed by low-dose or standard-dose radiation therapy works in treating patients with human papilloma virus (HPV) positive stage III-IVA oropharyngeal cancer. Radiation therapy uses high-energy x-rays to kill tumor cells. Drugs used in chemotherapy work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving radiation therapy with chemotherapy may kill any tumor cells that remain after surgery. It is not yet known how much extra treatment needs to be given after surgery.

Detailed Description

PRIMARY OBJECTIVES:

I. Accrual, risk distribution, and surgical quality will be used to determine the feasibility of a prospective multi-institutional study of transoral surgery for HPV positive (+) oropharynx cancer followed by risk-adjusted adjuvant therapy.

II. To assess the oncologic efficacy following transoral resection and adjuvant therapy in patients determined to be at "intermediate risk" after surgical excision, the 2-year progression free survival (PFS) rate will be examined.

SECONDARY OBJECTIVES:

I. To estimate the patient distribution with various histologic risk features. II. To assess and compare early and late toxicities associated with transoral surgery (TOS) and the different doses of adjuvant postoperative radiotherapy (PORT).

III. To evaluate swallowing function before and after TOS and risk-adjusted adjuvant therapy.

IV. To evaluate quality of life (QOL), swallowing perception and performance, voice outcomes, and head and neck symptoms.

TERTIARY OBJECTIVES:

I. To correlate tumor TP53 mutation and other associated mutation profile with pathologic findings, with PFS and other outcome parameters in patients with resectable HPV-associated oropharyngeal squamous cell carcinoma (OPSCC) after the above treatments.

II. To evaluate radiation resistance markers, including excision repair cross complementing 1 (ERCC1) single nucleotide polymorphism and protein expression, and correlate them with treatment efficacy.

III. To investigate the usefulness of biomarkers in predicting progression-free survival and biomarkers, including tumor ERCC1, epidermal growth factor receptor (EGFR), plasma cytokine/chemokines, cellular immunity to HPV, and oral HPV deoxyribonucleic acid (DNA).

OUTLINE: Patients are classified by risk status (low risk, intermediate risk, or high risk) and assigned to the appropriate treatment group. Patients classified as intermediate risk are randomized to 1 or 2 treatment arms.

ARM A (low risk): Patients undergo transoral surgical resection of the oropharyngeal tumor.

ARM B (intermediate risk): Patients undergo transoral surgical resection of the oropharyngeal tumor. Patients then undergo low-dose intensity modulated radiation therapy (IMRT) once daily (QD) five days a week for 5 weeks.

ARM C (intermediate risk): Patients undergo transoral surgical resection of the oropharyngeal tumor. Patients then undergo standard-dose IMRT QD five days a week for 6 weeks.

ARM D (high risk): Patients undergo transoral surgical resection of the oropharyngeal tumor. Patients then undergo standard-dose IMRT QD five days a week for 6-7 weeks. Patients also receive cisplatin intravenously (IV) over 60 minutes or carboplatin IV over 30 minutes on days 1, 8, 15, 22, 29, 36, and 43 during radiation therapy.

After completion of study treatment, patients are followed up every 3 months for 2 years and then every 6 months for 1 year.
