Excerpt
It has been 18 years since the first guidelines on PET response criteria were released [
1] (with little supporting data at that time) and 15 years since the first successful use of PET for evaluation of a molecularly targeted therapy (imatinib) was published [
2]. This latter study demonstrated the huge potential of PET imaging in assessing tumor response early after treatment initiation, at a time when conventional criteria based on size measurements (RECIST) were found to be unsatisfactorily. Since then, numerous studies using FDG PET as a surrogate marker to evaluate response to therapy have been published; PET Response Criteria In Solid Tumors (PERCIST) have been introduced [
3,
4] and data regarding repeatability of PET have been published, supporting the use of thresholds to discriminate between responders and non-responders [
5,
6]. Nonetheless, unfortunately, FDG PET is far from being a standard tool in clinical trials assessing new antineoplastic tools, but there have been indeed relevant progress. …
