PET(-CT) for staging of lung cancer
• PET improves accuracy of staging
– High negative predictive value of PET for mediastinal lymph
nodes
• Improved staging has impact on treatment strategy
– Selective irradiation of mediastinum based on PET results in
low rates of nodal failure
• Residual FDG uptake after treatment correlates with
location of high uptake pre-treatment and is
associated with worse outcome
• What is the impact of PET on delineation?
