Individualized Treatment in Treating Patients With Stage II-IVB Nasopharyngeal Cancer Based on EBV DNA

There are two study questions we are asking in this randomized phase II/III trial based on a blood biomarker, Epstein Barr virus (EBV) deoxyribonucleic acid (DNA) for locoregionally advanced non-metastatic nasopharyngeal cancer. All patients will first undergo standard concurrent chemotherapy and radiation therapy. When this standard treatment is completed, if there is no detectable EBV DNA in their plasma, then patients are randomized to either standard adjuvant cisplatin and fluorouracil chemotherapy or observation. If there is still detectable levels of plasma EBV DNA, patients will be randomized to standard cisplatin and fluorouracil chemotherapy versus gemcitabine and paclitaxel. Radiation therapy uses high energy x rays to kill tumor cells. Drugs used in chemotherapy, such as cisplatin, fluorouracil, gemcitabine hydrochloride, and paclitaxel 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 giving cisplatin and fluorouracil is more effective than gemcitabine hydrochloride and paclitaxel after radiation therapy in treating patients with nasopharyngeal cancer.

Stanford is currently accepting patients for this trial.

Inclusion Criteria:

   - Biopsy proven (from primary lesion and/or lymph nodes) diagnosis of cancer of the

   - Patients must have detectable pretreatment plasma EBV DNA, determined by the central
   lab prior to Step 2 registration

   - Stage II-IVB disease (American Joint Committee on Cancer [AJCC], 7th edition [ed.])

      - History/physical examination by a Medical Oncologist or Clinical Oncologist or
      Radiation Oncologist or Ear, Nose, Throat specialist (ENT), which must include an
      endoscopic evaluation, a complete list of current medications, and assessment of
      weight and weight loss in the past 6 months within 21 days prior to registration

      - Evaluation of tumor extent with magnetic resonance imaging (MRI) of the
      nasopharynx and neck within 28 days prior to registration; if MRI is medically
      contraindicated, obtain computed tomography (CT) scan with =< 3 mm contiguous
      slices with contrast and bone windows (to evaluate base of skull involvement);
      Note: If a treatment planning CT scan is used, it must be with =< 3 mm contiguous
      slices with contrast and be read by a radiologist

      - To rule out distant metastasis, patients must undergo the following imaging
      within 28 days prior to registration:

         - A CT scan with contrast of the chest, abdomen, and/or pelvis or a total body
         positron emission tomography (PET)/CT scan (non-contrast PET/CT is

         - A bone scan only when there is suspicion of bone metastases (a PET/CT scan
         can substitute for the bone scan)

   - Zubrod performance status 0-1 within 21 days prior to registration

   - Absolute neutrophil count (ANC) >= 1,500 cells/mm^3

   - Platelets >= 100,000 cells/mm^3

   - Hemoglobin >= 8.0 g/dl (Note: the use of transfusion or other intervention to achieve
   hemoglobin [Hgb] >= 8.0 g/dl is acceptable)

   - Total bilirubin =< 1.5 x institutional upper limit of normal (ULN)

   - Aspartate aminotransferase (AST) or alanine aminotransferase (ALT) =< 1.5 x
   institutional ULN

   - Alkaline phosphatase =< 1.5 x institutional ULN

   - Serum creatinine =< 1.5 mg/dl or calculated creatinine clearance (CC) >= 50 ml/min
   determined by 24-hour urine collection or estimated by Cockcroft-Gault formula

   - Negative serum pregnancy test within 14 days prior to registration for women of
   childbearing potential

   - Women of childbearing potential and male participants who are sexually active must
   agree to use a medically effective means of birth control throughout protocol

   - Patient must provide study specific informed consent prior to study entry, including
   the mandatory pre-treatment plasma EBV DNA assay

Exclusion Criteria:

   - Prior invasive malignancy (except node negative, non-melanomatous skin cancer) unless
   disease free for a minimum of 1095 days (3 years) (for example, carcinoma in situ of
   the breast, oral cavity, or cervix are all permissible)

   - Prior systemic chemotherapy for the study cancer; note that prior chemotherapy for a
   different cancer is allowable; however, at least 6-weeks recovery is necessary if the
   last regimen included nitrosourea or mitomycin

   - Prior radiotherapy to the region of the study cancer that would result in overlap of
   radiation therapy fields

   - Patients with hearing loss assessed to be primarily sensorineural in nature, requiring
   a hearing aid, or intervention (i.e. interfering in a clinically significant way with
   activities of daily living); a conductive hearing loss from tumor-related otitis media
   is allowed

   - >= Grade 2 peripheral sensory neuropathy (CTCAE, v. 4.0)

   - Severe, active co-morbidity, defined as follows:

      - Major medical or psychiatric illness, which in the investigator's opinion would
      interfere with the completion of therapy and follow up or with full understanding
      of the risks and potential complications of the therapy

      - Unstable angina and/or uncontrolled congestive heart failure

      - Myocardial infarction within the last 6 months
