Standard treatment for glioblastomas includes radiation and chemotherapy with a drug called temozolomide (Temodar); however, glioblastomas frequently develop resistance to standard treatment and recur or progress. Glioblastomas are known to have decreased levels of oxygen compared to normal tissues. There is evidence that these lower oxygen levels in glioblastomas may contribute to their ability to resist treatment effects of radiation and chemotherapy. In this study we will look to increase the oxygen concentration within the glioblastoma by adding hyperbaric treatments (the experimental part of this study) to standard treatment with radiation and temozolomide in order to see whether increasing the oxygen concentration within the tumor increases the tumor-killing ability of standard radiation and chemotherapy.
In addition, the investigators are interested to evaluate the effect of this treatment protocol on a person's quality of life and level of stress, and, therefore, the investigators will ask subjects to complete several brief questionnaires while they are on-study.

The drug LBH589 (panobinostat) is an experimental (investigational) drug that is being tested for recurrent (returning) malignant gliomas. An investigational drug is one that has not been approved by the U.S. Food and Drug Administration (FDA). It belongs to a new class of drugs called "histone deacetylase inhibitors." Histones are proteins located in the nucleus of cells that bind to DNA, the chemical that makes up genes. These proteins help control which genes are turned "on" and "off." Studies have shown that drugs like panobinostat (LBH589) may lead to tumor cell death.
