Outcome rephrased

2%

Neck recurrence

“caused by PET strategy” “Not avoidable by CT”

6% Neck recurrence

92%

NPV for PET (12w)

“Very safe strategy”

Discussion ? % Saved LND relative to CT (12w) ? ? % PPV for PET (12w)

-> still too many LND?

Conclusions Not many neck recurrences occur Introduction of PET(12w) for LND selection is very safe It also seems to save unneeded LND, but unknown how many
