This partially randomized pilot phase I trial studies magnetic resonance imaging (MRI)-guided laser surgery and doxorubicin hydrochloride in treating patients with glioblastoma multiforme that has come back. The blood brain barrier is a separation of circulating blood from the tissue of the nervous system, preventing substances in the blood from entering the brain. MRI-guided laser ablation disrupts the BBB around the tumor which may allow cancer-killing substances to be carried directly to the tumor. Drugs used in chemotherapy, such as doxorubicin hydrochloride, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Using MRI-guided laser ablation prior to chemotherapy (doxorubicin hydrochloride) may result in a greater concentration of drug in the tumor to kill the cancer cells while limiting side effects.

PRIMARY OBJECTIVES:
I. To determine magnetic resonance (MR) imaging correlates of peritumoral blood-brain barrier (BBB) disruption after MRI-guided laser ablation (MLA).
II. To identify serum biomarkers of peritumoral BBB disruption after MLA, which can be used to establish peritumoral permeability scores.
III. To determine 6-month progression-free survival (6PFS) in patients who receive doxorubicin hydrochloride (doxorubicin) immediately following MLA and patients who receive doxorubicin beginning 6-8 weeks after MLA as compared to the historical control of bevacizumab alone.
SECONDARY OBJECTIVES:
I. To determine the predictive value of the peritumoral permeability score for patient outcome as measured by 6-PFS rate.
II. To determine overall survival in patients who receive doxorubicin immediately following MLA and patients who receive doxorubicin beginning 6-8 weeks after MLA as compared to the historical control of bevacizumab alone.
III. To evaluate quality of life (QOL) using Karnofsky performance status and the Mini-Mental State Examination (MMSE) in patients who receive doxorubicin immediately following MLA and patients who receive doxorubicin beginning 6-8 weeks after MLA.
EXPLORATORY OBJECTIVES:
I. To investigate the correlation between the duration of MLA-induced BBB disruption (as determined by MRI correlates and biomarkers) and 6-month PFS.
II. To determine the effects of MLA treatment on patient’s tumor-specific immune responses.
OUTLINE: Patients are assigned or randomized to 1 of 2 treatment arms.
ARM B: Patients undergo MLA. Beginning 6-8 weeks later, patients receive doxorubicin hydrochloride intravenously (IV) over 5 minutes once weekly for 6 weeks in the absence of disease progression or unacceptable toxicity.
ARM C: Patients undergo MLA. Beginning within 7 days, patients receive doxorubicin hydrochloride IV over 5 minutes once weekly for 6 weeks in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed up every 8 weeks for 2 years.
