Background: Predicting and monitoring PRRT is based upon NET overexpression of somatostatin receptor (SSR) to deliver targeted isotope therapy. Imaging SSR expression is ~60% accurate as a predictor of efficacy. However, it and other imaging modalities e.g., CT/MRI, have utility for monitoring response. Specific blood NET gene expression (Positive Predictor Quotient- [PPQ]) is accurate in predicting PRRT response (93–97%, Bodei et al. EJNMMI 2018). The utility of NET tran...
