The Role of Adding Somatostatin Analogues to Peptide Receptor Radionuclide Therapy as a Combination and Maintenance Therapy

Purpose: Although somatostatin analogues (SSA) and peptide receptor radionuclide therapy (PRRT) are validated therapies in patients with advanced gastroenteropancreatic neuroendocrine tumors (GEP-NETs), it remains unclear whether SSA combined with PRRT or as maintenance therapy can provide prolonged survival compared to patients treated with PRRT alone. In this retrospective study, we aimed to investigate whether there is a survival benefit to adding SSA to PRRT as a combination therapy and/or maintenance therapy. Experimental Design: The investigation included 168 patients with unresectable GEP-NETs treated at the University Hospital Bonn, Germany. The patients were divided into two main groups: PRRT monotherapy (N=81, group 1) and PRRT plus SSA (N=87, group 2) as combined therapy with PRRT and/or as maintenance therapy after PRRT. Results: Data for overall survival (OS) were available from 168 patients, of whom 160 had data for progression-free survival (PFS). The median PFS was 27 months in group 1 vs. 48 months in group 2 (p = 0.012). The median OS rates were 47 months in group 1 and 91 months in group 2 (p < 0.001). The death-event rates were lower in group 2 (26%) than in group 1 (63%). SSA as a combination therapy with PRRT and/or as a maintenance therapy showed a clinical benefit rate (objective response or stable disease) of 95%, which was significantly higher than group 1 (79%). Conclusions: SSA as a combination therapy and/or maintenance therapy may play a significant role in tumor control in patients with GEP-NET who underwent a PRRT.
