HBO-XRT: Dose Escalation Study of Hyperbaric Oxygen With Radiation and Chemotherapy to Treat Squamous Cell Carcinoma of the Head and Neck
Study Details
Study Description
Brief Summary
This research is being done because we do not know the best treatment for advanced Squamous Cell Carcinoma of the Head and Neck. These cancers have been treated with a combination of surgery, radiation and chemotherapy in varying combination. When the tumor is inoperable, radiation therapy is used with or without chemotherapy in the hope of curing the tumor.
Recently, it has become recognized as generalized knowledge that cancer cells are hypoxic (low oxygen concentration). Because of the low oxygen concentrations, many cancer treatments have not been successful. The theory behind this study is to give oxygen to patients prior to chemotherapy and radiation in hopes of generating greater results in killing cancer cells. The purpose of this study has two main objectives. The primary objective is to determine patient tolerance to each arm of the trial.
The second objective is to determine the feasibility of treatment delivery and acute toxicities associated with each regimen.
It is our intention to undertake a randomized and controlled trial should this Phase I trial prove successful in terms of patient tolerance.

Phase 1 |
Detailed Description
The goal of this study is to see if patients can tolerate HBO therapy up to five days a week.
Three patients in Arm 1 (HBO on Monday and Friday) will be observed throughout their course of concomitant radiation, chemo and hyperbaric therapy. If these patients appear to tolerate this protocol well, and no adverse effects that can be directly attributed to HBO are observed, then three more patients will be recruited for Arm 2 (HBO on Monday, Wednesday, and Friday). If again these patients appear to tolerate this protocol well, and no adverse effects that can be directly attributed to HBO are observed, then a third group of three patients will be recruited for Arm 3 (HBO Monday through Friday).
If Grade IV acute toxicity is reported for a single patient in any of the arms, 3 more patients will be recruited in the same arm. If no further adverse events occur, the protocol progresses to the next arm. If Grade IV acute toxicity is observed even a single patient, the study will be stopped.
Tumor and/or lymphatic tissue specimens will be obtained prior to starting treatment. Tumor tissue specimens will be analyzed to determine whether there is a predictive susceptibility of tumors to HBO sensitization using currently defined biomarkers known to correlate with survival.
