195 / 1498
UK RAPID; EORTC/LYSA H10
RT or no RT in PET-negative early stage
HL
•
Central PET review necessary
•
More events in PET- patients with chemo only
•
Similar findings but opposite conclusions (8 vs 20 and 8 vs 25 events) between
RAPID
1
and H10
2
•
Rapid failed to demonstrate non-inferiority (HR 1.57; p=0.27) with PFS
differences of up to 8.8% (ITT) and 11.0% (per protocol)
•
No difference between PET+ and PET- patients –questionable role of PET in
this setting!
•
Deleting RT in PET- early stage HL still experimental
