Description:
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.

skin cancer) unless disease free for a minimum of 3 years; noninvasive cancers (for
example, carcinoma in situ of the oral cavity, larynx, breast or cervix are all
permissible) are permitted even if diagnosed and treated < 3 years ago.
- Patient must not have had previous systemic chemotherapy for the study cancer. (Note:
prior chemotherapy for a different cancer is allowable).
- Patient must not be receiving any other investigational agents.
- Patient must not have had any prior radiotherapy to the region of the study cancer
that would result in overlap of radiation therapy fields
- Patient must not have any life-threatening comorbid illnesses e.g. stroke with major
sequelae or myocardial infarction/ unstable angina within the preceding 3 months or
psychiatric illness/social situations that would limit compliance with study
requirements.
- Patient must not be pregnant or breastfeeding. If a woman of childbearing potential,
patient must agree to use medically acceptable forms of contraception.
