Expedited Laser Interstitial Thermal Therapy + Chemoradiation For Newly Diagnosed High Grade Gliomas

The investigators of this study want to see if shortening the total treatment time for brain tumors is safe.The treatment for participant\'s brain tumors is laser surgery (Laser Interstitial Thermal Therapy (LITT)) followed by radiation with chemotherapy. For participants, the total time of treatment from surgery to the end of radiation and chemotherapy is about l 0 weeks long. This study asks whether it is safe to shorten the total treatment to 7 weeks. To shorten the total treatment time, investigators want to see if it is safe to start radiation with chemotherapy within 5 days after surgery. Usually patients start their radiation with chemotherapy about 21-28 days after the surgery. Shortening the total time of treatment may allow investigators to kill the cancer cells more effectively.
