Background: Peptide receptor radionuclide therapy (PRRT) is based on tumor somatostatin receptor (SSR) overexpression to deliver targeted isotope therapy. Functional imaging of SSR expression (SRE) is used as a predictor of efficacy, but there is no method to objectively predict PRRT efficacy. We report the efficacy of Predictive Quotient Index (PQI) to predict the utility of PPRT. PQI is derived from circulating NET transcript analysis (NETest) integrated with the tu...

Background: The efficacy of PRRT is based upon NET over expression of somatostatin receptor (SSR) to deliver targeted isotope therapy. SSR expression (Krenning scale) compared to Predictive Quotient Index (PQI) (circulating NET transcript analysis mathematically integrated with grade) indicates the latter is more accurate for predicting PRRT efficacy. We evaluated whether PQI was specifically predictive or was prognostic for PRRT compared to other therapeutic strategi...
