Brief Summary:
This clinical trial studies the intensity of adjuvant ("helper") therapy required in p16 positive oropharynx cancer patients, who have had all known disease removed surgically by a minimally invasive approach, and who have extracapsular spread in their lymph nodes. Patients can consent to participate in either the randomized (physician chooses radiotherapy arm or radiotherapy & cisplatin arm) or non-randomized (patient chooses radiotherapy arm or radiotherapy & cisplatin arm) pathways. After the surgery, receive either radiation alone, or radiation and weekly cis-platinum during therapy. Patients are then followed for cancer, functional and quality of life outcomes.

Primary Outcome Measures :
  1. Number of Participants With Disease-free Survival (DFS) [ Time Frame: 1 year ]
  2. Locoregional Control [ Time Frame: Up to 2 years ]
    Rate of patients with no recurrence at original oropharyngeal site or in the neck nodal basins.


Secondary Outcome Measures :
  1. Rate of Distant Metastasis [ Time Frame: Up to 2 years ]
    Assessed by biopsy or imaging-detected recurrent disease at sites away from the original primary and cervical zone.

  2. Disease Specific Survival [ Time Frame: 1 year ]
  3. Number of Complications/Acute Toxicity by Organ Class [ Time Frame: Approximately 18 weeks ]
    -Assessed by the National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) version 4.0.

  4. Change in Quality of Life as Measured by the MD Anderson Dysphagia Inventory [ Time Frame: Baseline, 1 month, 6 months, 12 months, and 24 months ]
    • Each item is scored on a 5 point Likert scale (strongly disagree, disagree, no opinion, agree, strongly agree). Strongly agree = 1, Disagree = 2, No opinion = 3, Agree = 4, and Strongly Agree = 5
    • The lower the score the lower the quality of life

  5. Change in Cognitive Function as Measured by Cognitive Failures Questionnaire [ Time Frame: Baseline, 1 month, 12 months, and 24 months ]
    • 25 questions to assess the frequency in which participants experience cognitive failures including forgetfulness, distractibility, and false triggering
    • Answers range from 0 = never to 4 = very often
    • The higher the score the worse the cognitive failures the participant has experienced

  6. Change in Quality of Life as Measured by Neck Dissection Impairment Index (NDII) [ Time Frame: Baseline, 12 months, and 24 months ]
    -The NDII consists of 10 questions; each with a 5 level ordinally scaled response option ranging from "not at all" to "a lot". The response for each item is then scored from 1 to 5, with 5 denoting higher quality of life (Not at all) and 1 being the least (A lot).

  7. Change in Quality of Life as Measured by University of Michigan Xerostomia Questionnaire [ Time Frame: Baseline, 1 month, 6 months, 12 months, and 24 months ]
    • It contains 8 questions regarding dryness either during feeding or in the unstimulated state. Participants rate each item from 0 to 10, where 10 indicates the maximum dryness or discomfort due to dryness.
    • The higher the score the worse the participant's xerostomia

  8. Change in Hearing as Measured by Hearing Handicap Inventory - Adult [ Time Frame: Baseline, 1 month, and 12 months ]
    • 11 item questionnaire to identify issues with hearing
    • Answers are yes = 4, sometimes = 2, and no = 0
    • The higher the score the more issues the participant has with hearing

  9. Change in Quality of Life as Measured by Scale of Subjective Total Taste Acuity [ Time Frame: Baseline, 1 month, 6 months, and 12 months ]
    • 1 question that asks about taste acuity
    • Answers are 0 = same taste acuity as before treatment; 1 = mild loss of taste acuity, but not inconvenient in daily life; moderate loss of taste acuity, and sometimes inconvenient in daily life; severe loss of taste acuity, and frequently inconvenient in daily life; and 4 = almost complete or complete loss of taste acuity
    • The higher the score the worse the participant's taste acuity

  10. Change in Quality of Life as Measured by Speech Handicap Index [ Time Frame: Baseline and 12 months ]
    • 31 questions regarding participant's speech and the effects of speech on his/her life
    • The answers for the first 30 questions range from 0 = never to 4 = always and the answers for the 31st question ranges from 0 = excellent to bad = 4
    • The higher the score the worse the participant's speech is affecting his/her life

  11. Change in Quality of Life as Measured by EORTC QLQ-C30 [ Time Frame: Baseline, 1 month, 6 months, 12 months, and 24 months ]
    • 30 questions designed to assess the quality of life of cancer patients
    • The first 28 questions have answers that range from 1=not at all to 4 = very much. The higher score indicates a worse quality of life
    • The last 2 questions have answers that range from 1 = very poor to 7 = excellent. The higher score indicates a better quality of life
