Reduced-Dose Intensity-Modulated Radiation Therapy With or Without Cisplatin in Treating Patients With Advanced Oropharyngeal Cancer
This randomized phase II trial studies the side effects and how well modestly reduced-dose intensity-modulated radiation therapy (IMRT) with or without cisplatin works in treating patients with oropharyngeal cancer that has spread to other places in the body (advanced). Radiation therapy uses high energy x rays to kill tumor cells. Drugs used in chemotherapy, such as cisplatin, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. It is not yet known whether IMRT is more effective with or without cisplatin in treating patients with oropharyngeal cancer.
A Randomized Phase II Trial for Patients With p16 Positive, Non-Smoking Associated, Locoregionally Advanced Oropharyngeal Cancer
- To select the arm(s) achieving a 2-year progression-free survival rate of >= 85% without unacceptable swallowing toxicity at 1 year.
- To determine patterns of failure (locoregional relapse versus distant) and survival (overall and progression-free) at 6 months and 2 years.
II. To determine acute toxicity profiles at the end of radiation therapy and at 1 and 6 months.
III. To determine late toxicity profiles at 1 and 2 years. IV. To determine patient-reported swallowing outcomes at 6 months and 1 and 2 years.
- To determine the predictive value of 12-14 week, post-treatment fludeoxyglucose F 18 (FDG)-positron emission tomography (PET)/computed tomography (CT) for locoregional control and progression free survival (PFS) at 2 years.
VI. To determine the predictive value of blood and tissue biomarkers for disease outcomes at 2 years.
VII. To determine swallowing recovery per videofluoroscopy imaging at 2 years.
OUTLINE: Patients are randomized to 1 of 2 treatment arms.
ARM I: Patients undergo IMRT once daily (QD) five days a week for 6 weeks to a total dose of 60 Gy and receive cisplatin intravenously (IV) over 30-60 minutes weekly during radiation therapy for 6 doses in the absence of disease progression or unacceptable toxicity.
ARM II: Patients undergo IMRT five days a week for 5 weeks to a total dose of 60 Gy in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed up every 3 months for 2 years, every 6 months for 3 years, and then annually thereafter.

- STEP 1: REGISTRATION
- Pathologically (histologically or cytologically) proven diagnosis of squamous cell carcinoma (including the histological variants papillary squamous cell carcinoma and basaloid squamous cell carcinoma) of the oropharynx (tonsil, base of tongue, soft palate, or oropharyngeal walls); cytologic diagnosis from a cervical lymph node is sufficient in the presence of clinical evidence of a primary tumor in the oropharynx; clinical evidence should be documented, may consist of palpation, imaging, or endoscopic evaluation, and should be sufficient to estimate the size of the primary (for T stage)
- Patients must have clinically or radiographically evident measurable disease at the primary site or at nodal stations; tonsillectomy or local excision of the primary without removal of nodal disease is permitted, as is excision removing gross nodal disease but with intact primary site; limited neck dissections retrieving =< 4 nodes are permitted and considered as non-therapeutic nodal excisions
- Immunohistochemical staining for p16 must be performed on tissue, and this tissue must be submitted for central review; fine needle aspiration (FNA) biopsy specimens may be used as the sole diagnostic tissue if formalin-fixed paraffin-embedded cell block material is available for p16 immunohistochemistry; FNA specimens prepared with adequate p16 testing in this manner are acceptable to submit for central review; if the p16 preparation is not adequate, additional specimens will be required to establish p16 status; centers are encouraged to contact the pathology chairs for clarification
- Clinical stage T1-T2, N1-N2b or T3, N0-N2b (American Joint Committee on Cancer [AJCC], 7th edition [ed.]) including no distant metastases based on the following diagnostic workup:
- General history and physical examination within 56 days prior to registration
- Fiberoptic exam with laryngopharyngoscopy (mirror and/or fiberoptic and/or direct procedure) within 70 days prior to registration
- One of the following combinations of imaging is required within 56 days prior to registration:
- A CT scan of the neck (with contrast) and a chest CT scan (with or without contrast)
- Or a magnetic resonance imaging (MRI) of the neck (with contrast) and a chest CT scan (with or without contrast)
- Or a CT scan of neck (with contrast) and a PET/CT of neck and chest (with or without contrast)
- Or an MRI of the neck (with contrast) and a PET/CT of neck and chest (with or without contrast)
- Note: a CT scan of neck and/or a PET/CT performed for the purpose of radiation planning may serve as both staging and planning tools
- Patients must provide their personal smoking history prior to registration; the lifetime cumulative history cannot exceed 10 pack-years; the following formula is used to calculate the pack-years during the periods of smoking in the patient's life; the cumulative total of the number of pack-years during each period of active smoking is the lifetime cumulative history
- Number of pack-years = (frequency of smoking [number of cigarettes per day] x duration of cigarette smoking [years])/20
- Note: twenty cigarettes is considered equivalent to one pack; the effect of non-cigarette tobacco products on the survival of patients with p16-positive oropharyngeal cancers is undefined; cigar and pipe tobacco consumption is therefore not included in calculating the lifetime pack-years; marijuana consumption is likewise not considered in this calculation; there is no clear scientific evidence regarding the role of chewing tobacco-containing products in this disease; investigators are discouraged from enrolling patients with a history of very sustained use (such as several years or more) of non-cigarette tobacco products alone
- Zubrod performance status of 0-1 within 56 days prior to registration
Absolute neutrophil count (ANC) >= 1,500 cells/mm3
Platelets >= 100,000 cells/mm3
- Hemoglobin >= 8.0 g/dl; Note: the use of transfusion or other intervention to achieve hemoglobin (Hgb) >= 8.0 g/dl is acceptable
- Serum creatinine =< 1.5 mg/dl or creatinine clearance (CC) >= 50 ml/min determined by 24-hour collection or estimated by Cockcroft-Gault formula
- Bilirubin =< 2 mg/dl
- Aspartate aminotransferase (AST) or alanine aminotransferase (ALT) =< 3 x the upper limit of normal
- Negative serum pregnancy test within 14 days prior to registration for women of childbearing potential
Patients who are human immunodeficiency virus (HIV) positive but have no prior acquired immune deficiency syndrome (AIDS)-defining illness and have cluster of differentiation (CD)4 cells of at least 350/mm3 are eligible; HIV-positive patients must not have multi-drug resistant HIV infection or other concurrent AIDS-defining conditions; patients must not be seropositive for hepatitis B (hepatitis B surface antigen positive or anti-hepatitis B core antigen positive) or seropositive for hepatitis C (anti-hepatitis C antibody positive); however, patients who are immune to hepatitis B (anti-hepatitis B surface antibody positive) are eligible (e.g. patients immunized against hepatitis B)
- The patient must provide study-specific informed consent prior to study entry, including consent for mandatory submission of tissue for required, central p16 review
- Patients who speak English (or read one of the languages for which a translation is available must consent to complete the mandatory dysphagia-related patient reported instrument (MDADI); if the patient cannot understand spoken English and reads only languages not available in the MDADI translations, the patient can still participate in the trial, as this has been factored into the trial statistics; for all other patients, the MDADI is mandatory as it is included in the primary endpoint to be studied
- STEP 2: RANDOMIZATION
- p16 positive by immunohistochemistry (defined as greater than 70% strong nuclear or nuclear and cytoplasmic staining of tumor cells, confirmed by central pathology review)

I am a radiation oncologist who specializes in the treatment of head and neck, lung, and skin cancers. I serve on national guidelines committees outlining the best practices for these cancers. I design clinical trials to improve treatment of these cancers. I give lectures and design courses to help others learn more about how to best treat these cancers.
