Official Title: Application of Diffusion Tensor Imaging and Tractography in Pediatric Tumor Surgery
Brief Summary: The goal of this project will be to demonstrate that Synaptive Medical's Diffusion Tensor Imaging(DTI) product functionality used in pre-operative planning and intraoperative surgical navigation, improves clinical outcomes corresponding to a reduction in neurological and neuropsychological deficits in pediatric brain tumor surgery.
Detailed Summary:
Brain tumours are the most common form of solid tumours in children which often arise from the cerebellum. Treatment involves a complete resection of the tumour. Although surgical resection may eliminate most of the malignancy, signs of post-neurologic deficit may present as a consequence to the treatment.
One such example is cerebellar mutism syndrome (CMS), a postoperative syndrome typically arising 1 to 2 days after resection of a midline posterior fossa tumor; it consists of diminished speech progressing to mutism, emotional lability, hypotonia, and ataxia. While some of the symptoms recover after a few months, neuropsychological testing shows long term deficits in language (agramatism), executive function and verbal memory.
This study aims to investigate whether the use of Synaptive Medical's BrightMatter™ technology can help neurosurgeons better visualize and plan surgeries by avoiding eloquent fiber tracts in the brain and cerebellum; thus minimizing damage pertaining to neurologic and motor functionality. The use of these products will also be assessed for improved clinical outcomes in pediatric tumor surgery.

Current Primary Outcome:
- Total volume of tract damage [ Time Frame: Assess the total volume of tract damage from baseline pre-operative examination through study completion (~ 1 year). ]Measure # of damaged tracts
- Total size of craniotomy (resection zone) [ Time Frame: Measure the total size of craniotomy from time of incision to end of surgery. (1 measurement/subject). ]Measure craniotomy size
Original Primary Outcome: Same as current
Current Secondary Outcome:
- Total time it takes for the surgeon to pre-operatively plan cranial approach. [ Time Frame: Assessed during start of surgical pre-operative plan through to end of surgical pre-operative plan (1 measurement/subject). ]Measured in hours
- Total OR time [ Time Frame: Assessed during surgical visit ]Measured in hours
- Duration of hospital stay [ Time Frame: Assessed during surgical visit up to 26 weeks ]Measured in # of days
- Total cost of surgery [ Time Frame: Assessed through study completion, an average of 1 year ]
- Quality of life assessment [ Time Frame: Assessed during surgical visit up to 26 weeks ]Measured using a standard questionnaire known as the WHOQOL-BREF questionnaire-World Health Organization Quality of Life Assessment
- Functional testing [ Time Frame: Assessed during surgical visit up to 26 weeks ]Measured using a routine functional impairment test for the pediatric population known as the Lansky performance scale
- # deaths and complications with surgery [ Time Frame: Assessed post-operatively after each surgery. Patient is followed until study completion (~ 1 year). ]Number of cases
Original Secondary Outcome: Same as current
