Study Type: Interventional

Official Title: Phase II Trial of Neoadjuvant Chemotherapy for HPV-Associated Squamous Cell Carcinoma of the Oropharynx Followed by Reduced Dose Radiotherapy/Chemoradiotherapy for Responders or Standard Dose Chemorad

Brief Summary: This study looks at the use of three cycles of chemotherapy given prior to radiation therapy in patients with cancer of the oral cavity and evidence of prior exposure to Human Papilloma Virus (HPV). Patients with cancer of the oral cavity who have evidence of exposure to HPV have a better prognosis than those who do not have such evidence of exposure to HPV. The main hypothesis of this study is that using three cycles of chemotherapy prior to embarking on radiation therapy will allow the use of reduced doses of radiation therapy and, therefore, less radiation induced side-effects. The primary objective is to determine the activity of this pre-radiation chemotherapy strategy along with reduced dose levels of radiation with or without chemotherapy during the radiation phase. The effectiveness of the strategy will be assessed at three months following the completion of the radiation therapy phase and also at two years following completion of the radiation therapy.

Detailed Summary:

Induction Chemotherapy TPF induction chemotherapy will be administered as published from the TAX 323 phase III trial. Specifically, each cycle will consist of docetaxel at a dose of 75 mg per square meter, administered as a 1-hour infusion on day 1, followed by cisplatin at a dose of 75 mg per square meter, administered as a 1-hour infusion on day 1, and fluorouracil at a dose of 750 mg per square meter per day, administered by continuous infusion on days 1 to 5. Induction chemotherapy will be given every 3 weeks for three cycles, unless there is distant disease progression, unacceptable toxic effects, or withdrawal of consent by the patient. All patients will be required to have a continuous venous access device such as a PICC line or Infusaport type device. This is standard of care for continuous infusion fluorouracil. Response assessment by examination, contrast-enhanced CT imaging and whole body PET-CT will be performed after the third treatment cycle. Radiotherapy or chemoradiotherapy will commence within 3-4 weeks from the conclusion of the induction program.

Selection for Radiation Alone vs. Chemoradiotherapy For CR/PR patients with CR at primary site following induction chemotherapy, locoregional therapy will be risk-adjusted according to baseline tumor stage/characteristics. Local therapy will be 1) radiotherapy as a single modality for Tx (T1-2), T0-1 or exophytic T2, N0-2a disease, or will be 2) concomitant chemoradiotherapy for Tx (T3), endophytic T2, T3, N2b-c disease. Patients with PR at primary site will receive concurrent chemotherapy and reduced dose radiation.

All SD/PD patients will receive concurrent chemotherapy and full dose radiation. Patients catalogued with disease progression on the basis of new distant metastatic disease spread (DM) during induction chemotherapy will be taken off protocol for con

Current Primary Outcome: Response (CR+PR) Status at 3 Months Post-therapy [ Time Frame: 3 months following completion of radiation phase ]

The 3-month response rate will be estimated using standard methods for estimating proportions and their 95% one-sided confidence intervals (CIs). Comparison to the historical control data will be carried out using a chi-square test for comparing proportions (or a Fisher exact test if an expected cell frequency in the 2x2 table is less than 5).
