Overview
Brief Summary
This is a Phase I study looking to evaluate the safety of dose escalated stereotactic radiotherapy (SRS) without exceeding the maximum tolerated dose in patients with high-risk human papilloma virus (HPV)- unassociated oropharyngeal squamous cancer.
Detailed Description
Human Papilloma Virus (HPV) is frequently found within tumor cells removed from patients diagnosed with oropharynx cancer. Tumors which do not contain HPV virus (termed "HPV-Negative") are not cured as frequently by radiation therapy. Tumors which do contain HPV in patients who have a history of cigarette smoking also are not cured as frequently by radiation. One way to potentially overcome this challenge is to deliver a more intense dose of radiation treatment to the tumor. The standard way to deliver radiation, termed Intensity Modulated Radiotherapy (IMRT), can protect normal tissues near tumors to a certain degree but not completely. Stereotactic radiosurgery (SRS) is a technique which can deliver radiation more precisely. This trial will test the safety of treating HPV-unassociated oropharynx tumors to higher radiation doses wth SRS (termed a "boost") after a standard course of IMRT has been given. In addition, the investigators will look at whether magnetic resonance imaging (MRI) scanning can detect treatment response in oropharynx tumors earlier than with standard tests.
