Arm A (MRI-guided Laser Ablation)
* MLA is a minimally invasive laser surgery currently FDA approved for cytoreductive treatment of brain tumors, both primary and metastatic. MLA employs a small incision in the scalp and skull, through which a thin laser probe is inserted and guided by MR imaging to the core of a tumor mass where it delivers hyperthermic ablation from the core to the rim.
* Participants will undergo DCE and DSC-MRI imaging at the following time points:
* no more than 3 weeks prior to MLA (OPTIONAL)
* within approximately 4 days after MLA
* 2-4 weeks after MLA
* Every 12 weeks (+/- 7 days) for the first year or until disease progression
|
Arm B (MRI-guided Laser Ablation, Doxorubicin, Etoposide)
* MLA is a minimally invasive laser surgery currently FDA approved for cytoreductive treatment of brain tumors, both primary and metastatic. MLA employs a small incision in the scalp and skull, through which a thin laser probe is inserted and guided by MR imaging to the core of a tumor mass where it delivers hyperthermic ablation from the core to the rim.
* Within 7 days of MLA (range 2-14 days) doxorubicin will be given intravenously on an outpatient basis weekly for 6 weeks at a dose of 25 mg/m\^2 over 5-30 minutes
* Following the completion of doxorubin, etoposide 50 mg/m\^2/day will be given orally for 21 days of each 28-day cycle (treatment can continue up to 24 cycles)
* Participants will undergo DCE and DSC-MRI imaging at the following time points:
* no more than 3 weeks prior to MLA (OPTIONAL)
* within approximately 4 days after MLA
* 2-4 weeks after MLA
* every 8 weeks (+/- 7 days) until 2 years have elapsed or disease progression, whichever comes first

SECONDARY outcome
Timeframe: Up to 48 weeks post MRI-guided laser heat ablation (Arm A) or up to 2 years post MRI-guided laser heat ablation (Arm B)Population: The one participant in Arm B did not consent to any procedures past 12 months post-MLA. There are time points not included because either the NSE was not detected in the samples or the samples were not collected.
* Arm A patients had blood drawn at the following time points: baseline, 3 days post-MLA, 2-4 weeks post-MLA, and every 12 weeks thereafter for 12 months post-MLA * Arm B patients had blood drawn at the following time points: baseline, 3 days post-MLA, week 1, week 2, week 3, week 4, week 5, week 6, and every 8 weeks for the first 2 years or until disease progression, whichever occurs first. * Neuron specific enolase is an enzyme involved in glycolysis, which is localized in neurons and axonal processes. Potentially, it escapes into the blood and CSF at the time of neural injury. Elevated serum NSE seemed to correlates with disruption in BBB following MLA and transient increase in BBB permeability.

Patient 1: Arm B (MRI-guided Laser Ablation, Doxorubicin, Etoposide)
n=1 Participants
* MLA is a minimally invasive laser surgery currently FDA approved for cytoreductive treatment of brain tumors, both primary and metastatic. MLA employs a small incision in the scalp and skull, through which a thin laser probe is inserted and guided by MR imaging to the core of a tumor mass where it delivers hyperthermic ablation from the core to the rim.
* Within 7 days of MLA (range 2-14 days) doxorubicin will be given intravenously on an outpatient basis weekly for 6 weeks at a dose of 25 mg/m\^2 over 5-30 minutes
* Following the completion of doxorubin, etoposide 50 mg/m\^2/day will be given orally for 21 days of each 28-day cycle (treatment can continue up to 24 cycles)
* Participants will undergo DCE and DSC-MRI imaging at the following time points:
* no more than 3 weeks prior to MLA (OPTIONAL)
* within approximately 4 days after MLA
* 2-4 weeks after MLA

SECONDARY outcome
Timeframe: Up to 48 weeks post MRI-guided laser heat ablation (Arm A) or up to 2 years post MRI-guided laser heat ablation (Arm B)Population: The one participant in Arm B did not consent to any procedures past 12 months post-MLA. There are time points not included because either the S100B was not detected in the samples or the samples were not collected.
* Arm A patients had blood drawn at the following time points: baseline, 3 days post-MLA, 2-4 weeks post-MLA, and every 12 weeks thereafter for 12 months post-MLA * Arm B patients had blood drawn at the following time points: baseline, 3 days post-MLA, week 1, week 2, week 3, week 4, week 5, week 6, and every 8 weeks for the first 2 years or until disease progression, whichever occurs first. * S100b is a low-molecular-weight Calcium-binding protein primarily found in astrocytic glial cells of the CNS. It is secreted by astrocytes for neuroprotective and -trophic cellular functions in the CNS. Elevated serum values can be associated with temporal changes in BBB integrity following MLA.

SECONDARY outcome
Timeframe: 1 year from MLAPopulation: Data was not collected for this outcome measure.
The linear regression model will used to investigate the correlation between MR imaging and peritumoral BBB disruption. To account for correlation among the repeated measures from the same patient, the longitudinal data will be analyzed with the use of linear generalized estimating equation (GEE). Whether the average measurements differ at the multiple time points will be evaluated through GEE model. Least-square means at each time points will be presented and standard errors will be calculated within the use of the GEE sandwich method when accounting for within-patient correlation.
Outcome measures
Outcome data not reported
SECONDARY outcome
Timeframe: 6 monthsPopulation: Data was not collected for this outcome measure.
Biomarkers with higher correlation coefficient (r approaching 1) will be given higher priority. A minimum r=0.5 is required for inclusion for further analysis and will be used as a peritumoral permeability score. This score will then be correlated with the patient outcome data (as measured by 6 month PFS rate) to determine whether it has a predictive value.
