Over three and a half years ago, I wrote a post about about early work looking at the possibility that a PET scan done anywhere from three days to a month out from the start of a new systemic therapy (chemo or EGFR inhibitor) for advanced NSCLC could be predictive of a good outcome or not.

Over the lasat decade, PET scans have become commonplace in the staging of NSCLC. There's an older post that reviews the concept of PET scans in providing metabolic imaging, as well as a podcast that provides a more complete discussion of PET scanning in oncology, with a focus on lung cancer.
