The biopsy may be either of the tonsil base of tongue and/or an involved neck node. 2 unstained slides and/or tissue block must be available from the initial diagnostic biopsy * Positive expression p16 and phosphorylated eIF4E is defined as \>=30% of tumor cells with cytological and/or nuclear staining * Age ≥ 18 and ≤ 65 years of age * Karnofsky Performance Status ≥ 80 * Adequate organ function, as follows: Adequate bone marrow reserve: absolute neutrophil count (ANC) ≥ 1.5 X 109/L, platelets ≥ 160 X 109/L, hemoglobin ≥ 12 g/dL Hepatic: total bilirubin within 1.5 X upper limit of normal (ULN) ; alkaline phosphatase (AP), aspartate transaminase (AST) and alanine transaminase (ALT) ≤ 2.5 X ULN (Patients with Gilbert's syndrome as the cause of hyperbilirubinemia may be eligible if total bilirubin ≤ 2.5 X UNL) Renal: Serum creatinine ≤ 1.3 mg/dL. Patients with serum creatinine \> 1.3 mg/dL may be eligible if creatinine clearance (CrCl) ≥ 55 mL/min based on the standard Cockroft and Gault formula. * Patients of childbearing potential must have a negative serum pregnancy test within 14 days of treatment.
