Thanks Lisa S. We have started using FET PET in the metastatic setting on a trial where we are collecting pathologic correlates. Our early experience would suggest it is quite promising. In the absence of this though, repeat MRI and or biopsy can be useful. We have not tended to use as much in GBM. We have favoured perfusion and permeability as well as spectroscopy...…...but even with this often a mix of treatment change and tumour on path. It is certainly not an exact science!! Happy to hear others experience in this space.
I really enjoyed this case study! I struggle with this question a lot in both the GBM and metastatic setting. Just wondering if people are performing FET PETs routine in this difficult scenario? And, if so, how reliable you have found it?
