FOLH1 and posterior cortical atrophy: In a previous analysis, we performed a machine learning-based analysis of 18F-DCFPyL (an 18F-labeled PSMA radioligand) PET/CT radiomics in patients with intermediate- to high-risk PCa scheduled for robot-assisted radical prostatectomy (RARP) with ePLND to predict LNI and high-risk tumor features, and observed excellent cross-validated predictive values [10].
