PET response criteria in solid tumors (PERCIST) is a set of rules that define when tumors in cancer patients improve ("respond"), stay the same ("stabilize"), or worsen ("progress") during treatment, using positron emission tomography (PET).
The criteria were published in May 2009 in the Journal of Nuclear Medicine (JNM).
[1] A pooled analysis from 2016 concluded that its application may give rather different results from RECIST, and might be a more suitable tool for understanding tumor response to treatment.
