Post-treatment follow-up

Goal : To assess the response and to diagnose recurrence when still resecable

• Standard Follow-up: • Clinical exam

• Every 4-6 months during 5 years • CT / year • Which place for new imaging modalities ? • MRI ? • FDG-PET/CT ?

Response assessment can be challenging • frequent post-treatment modifications (edema, residual fibrosis or scar tissue) can mimic persistent or recurrent disease • Systematic biopsies should be avoided because of radionecrosis risk
