Brief Summary:
The NeuroBlate® System (NBS) is a minimally invasive robotic laser thermotherapy tool that is being manufactured by Monteris Medical. Since it received FDA clearance in May 2009, the NBS has been used in over 2600 procedures conducted at over 70 leading institutions across United States. This is a prospective, multi-center registry that will include data collection up to 5 years to evaluate safety, QoL, and procedural outcomes including local control failure rate, progression free survival, overall survival, and seizure freedom in up to 1,000 patients and up to 50 sites.

Study Type : Observational
Estimated Enrollment : 3000 participants
Observational Model: Cohort
Time Perspective: Prospective
Official Title: Laser Ablation of Abnormal Neurological Tissue Using Robotic NeuroBlate System (LAANTERN) Prospective Registry
Actual Study Start Date : October 2015
Estimated Primary Completion Date : December 2030
Estimated Study Completion Date : December 2035

Primary Outcome Measures :
  1. Safety (Reportable adverse events) [ Time Frame: up to 12 months ]
    Safety profile described by the NBS and surgical-related AEs

  2. Reason for NeuroBlate [ Time Frame: Index procedure ]
    To identify the primary reason the NeuroBlate system was chosen for subject

  3. Number of patients demonstrating local control, overall survival, and seizure freedom (ENGEL and ILAE classifications) [ Time Frame: up to 12 months or last follow-up ]

    Collected for all subjects by disease etiology.

    Local control as measured by time to local tumor recurrence.

    Overall survival assessed by Kaplan-Meier method.

    Seizure freedom assessed for all subjects with epilepsy at time of last follow-up. The ENGEL surgical outcome scale is composed of four classes of epilepsy (Class I, Class II, Class III, Class IV) categorized by severity. The ILAE outcome scale contains six classes (Class 1, 2, 3, 4, 5, 6) categorized by severity.

  4. Change in Quality of Life [ Time Frame: up to 12 months or last follow-up ]

    Assessed by the following questionnaires:

    1. KPS (subjects with CNS malignancy): Scale ranged 0-100 measuring the ability of patients with cancer to perform ordinary daily activities
    2. FACT-Br (subjects with CNS malignancy): Measures general quality of life reflecting symptoms associated with brain malignancies across 5 scales (physical well-being social/family well-being, emotional well-being, functional well-being, and other)
    3. EQ-5D (all subjects): A generic measure of health consisting of the descriptive system and the visual analogue scale (VAS). The descriptive system assesses subject mobility, self-care, usual activities, pain/discomfort, and anxiety/depression. The VAS reports the subject's self-rated health
    4. QOLIE-31 (subjects with epilepsy): Contains 7 scales assessing emotional well-being, social functioning, energy/fatigue, cognitive functioning, seizure worry, medication effects, and overall quality of life for adults
