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

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.

Stanford is currently not accepting patients for this trial.

Eligibility


Inclusion Criteria:

   - REGISTRATION TO SURGERY (ARM S)

   - Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1

   - Patients must have newly diagnosed, histologically or cytologically confirmed squamous
   cell carcinoma or undifferentiated carcinoma of the oropharynx; patients must have
   been determined to have resectable oropharyngeal disease; patients with primary tumor
   or nodal metastasis fixed to the carotid artery, skull base or cervical spine are not
   eligible

   - Patients must have American Joint Committee on Cancer (AJCC) TNM tumor stage III, IV
   a, or IV b (with no evidence of distant metastases) as determined by imaging studies
   (performed < 4 weeks prior to pre-registration) and complete head and neck exam; the
   following imaging is required: computed tomography (CT) scan with IV contrast or
   magnetic resonance imaging (MRI)

   - Patients must have biopsy-proven cyclin-dependent kinase inhibitor 2A (p16)+
   oropharynx cancer; the histologic evidence of invasive squamous cell carcinoma may
   have been obtained from the primary tumor or metastatic lymph node; it is required
   that patients have nodal stage N1-N2b confirmed by clinical or radiographic methods
   (clinically N0 patients are not eligible)

   - Carcinoma of the oropharynx associated with HPV as determined by p16 protein
   expression using immunohistochemistry (IHC) performed by a Clinical Laboratory
   Improvement Amendments (CLIA) approved laboratory; using p16 antibody obtained from
   Roche mtm laboratories AG (CINtec, clone E6H4) is recommended

   - No prior radiation above the clavicles

   - Patients with a history of a curatively treated malignancy must be disease-free for at
   least two years except for carcinoma in situ of cervix and/or non-melanomatous skin
   cancer

   - Patients with the following within the last 6 months prior to pre-registration must be
   evaluated by a cardiologist and/or neurologist prior to entry into the study

   - Patients must not have evidence of extensive or "matted/fixed" pathologic adenopathy
   on preoperative imaging

   - Absolute neutrophil count >= 1,500/mm^3

   - Platelets >= 100,000/mm^3

   - Total bilirubin =< the upper limit of normal (ULN)

   - Calculated creatinine clearance must be > 60 ml/min using the Cockcroft-Gault formula

   - Women must not be pregnant or breast-feeding due to the teratogenicity of
   chemotherapy; all females of childbearing potential must have a blood test or urine
   study within 2 weeks prior to registration to rule out pregnancy; a female of
   childbearing potential is any woman, regardless of sexual orientation or whether they
   have undergone tubal ligation, who meets the following criteria: has not undergone a
   hysterectomy or bilateral oophorectomy; or has not been naturally postmenopausal for
   at least 24 consecutive months (i.e., has had menses at any time in the preceding 24
   consecutive months)

   - Patient must not have an intercurrent illness likely to interfere with protocol
   therapy or prevent surgical resection

   - Patients must not have uncontrolled diabetes, uncontrolled infection despite
   antibiotics or uncontrolled hypertension within 30 days prior to pre-registration

   - REGISTRATION/RANDOMIZATION TO STEP 2 - ARMS A, B, C AND D AND REGISTRATION TO STEP 3

   - Histopathologic assessment of surgical pathology must include examination for
   perineural invasion (PNI) and lymphovascular invasion (LVI) and reported as absent or
   present; the absence or presence of extracapsular extension (ECE) requires gross and
   microscopic assessment and is defined to be:

      - Absent (negative or nodal metastasis with smooth/rounded leading edge confined to
      thickened capsule/pseudocapsule),

      - Present - minimal (tumor extends =< 1 mm beyond the lymph node capsule), or

      - Present - extensive (gross, tumor extends > 1 mm beyond the lymph node capsule
      (includes soft tissue metastasis)

   - Patients must have ECOG performance status 0 or 1

   - Patient must be registered/randomized within 5-7 weeks following surgery

   - Women of childbearing potential and sexually active males are strongly advised to use
   an accepted and effective method of contraception
