Summary
•
Tumor localization and spread reflects cell origin
•
Increasing importance of molecular/genetic evaluation
•
Staging and evaluation of extent of surgery very
important in disease stratification/prognosis
•
Tumor spread may be subtle – diffusion changes only,
hidden sites (e.g. anterior skull base, spinal cul-de-sac)
•
MDT assessment offers optimal management
•
Neuraxial imaging must be the norm
•
Late imaging important to look for late recurrences and
late effects/secondary tumors
