•
PET
CMR does not = absence of microscopic disease
(although strongly
predictive of good prognosis)
•
Residual disease
detection
depends on:
•
Volume, intensity, background activity
•
Scanner detection limit
•
Microscopic disease
presence
depends on:
•
Histology, prognosis
•
Chemotherapy given
•
Initial bulk, residual soft tissue, local infiltration
•
Can RT be omitted in PET-ve patients?
•
Should we ignore residual masses if PET-ve?
