#2944 Soluble ST2 (sST2) Levels in the Management of Carcinoid Heart Disease in Patients with Neuroendocrine Cancer
Introduction: The identification of a sensitive biomarker to detect the presence and severity of carcinoid heart disease could allow more selective use of clinical and echocardiographic screening. ST2 is a protein belonging to the family of interleukin 1 receptors, present both in the isoform of transmembrane (ST2L) and in the soluble one (sST2). sST2 blocks the anti-inflammatory, anti-hypertrophic, and anti-fibrotic effects of cytokine IL-33 on the myocardium and recent studies have shown that sST2 levels increase in the blood of patients diagnosed with heart failure.

#2988 Epigenetic Treatment with Histone Deacetylase Inhibitor Enhances Uptake of [111In]In-DOTA-TATE by Increased SST2 Expression on Neuroendocrine Tumor Cells
Introduction: The somatostatin-2 receptor (SST2) is a target for peptide receptor radionuclide therapy (PRRT) in neuroendocrine tumors (NETs). By using epigenetic drugs, which can regulate gene transcription, PRRT efficacy may be further improved due to enhanced SST2 expression.

#3000 Patients with Somatostatin Receptor Type 2-Negative Neuroendocrine Tumors Have Sustained Inferior Survival Rates in a Propensity Score-Matched Analysis
Introduction: Sufficient expression of somatostatin receptor type 2 (SST2) in neuroendocrine tumors (NETs) is crucial for treatment with unlabelled somatostatin analogues (SSAs), or peptide receptor radionuclide therapy (PRRT) using radio-labelled SSAs. Impaired prognosis has been described for SST2-negative NET patients, however studies comparing matched SST2-positive and -negative subjects are missing.

#2905 DNA Methyltransferase Inhibitor Hydralazine Induces Upregulation of Somatostatin Type 2 Receptors in Human Neuroendocrine Tumor Cells
Introduction: Epidrugs like DNA methyltransferase inhibitors (DNMTi) can increase somatostatin receptor type 2 (SST2) expression in neuroendocrine tumor (NET) cells in vitro and in vivo. This effect could be used for NET patients with low SST2 expression who are currently ineligible for somatostatin analogue (SSA) treatment. However, the DNMTi known to stimulate SST2 have either a high toxicity profile or are not yet approved.

#19 Antitumor activity of Pasireotide (SOM230) alone and in combination with Everolimus (RAD001) in DU-145 human prostate cancer model
Introduction: Pasireotide (SOM230) is a novel multi-receptor ligand somatostatin analogue with high affinity for somatostatin receptor subtypes sst1,2,3 and sst5. Like octreotide, which binds primarily to sst2, it inhibits hypersecretion of hormones from patients with functional pituitary tumors and gastroenteropancreatic neuroendocrine (GEP/NET) tumors. In addition, tumor shrinkage has been observed with both compounds in patients with acromegaly, Cushing’s disease and GEP/NETs, but its tumor-reducing mechanism of action has so far not been revealed. In patients with breast and liver cancer, octreotide had little or no antitumor activity.

#131 Efficacy and safety results from a Phase II study of pasireotide (SOM230) in the treatment of patients with metastatic NETs refractory or resistant to octreotide LAR
Introduction: Pasireotide, a multi-receptor targeted somatostatin analogue, has 30-, 5- and 39-fold greater affinity for sst1,3 and sst5 receptors, respectively, and a slightly lower affinity for sst2, than octreotide. Because of this multi-receptor binding profile, pasireotide may be effective in controlling symptoms of carcinoid syndrome in patients with gastroenteropancreatic neuroendocrine tumors (NETs) who are no longer responsive to currently available somatostatin analogues.

#143 Association of somatostatin receptor 2 immunohistochemical expression with [111In]-DTPA octreotide scintigraphy and [68Ga]-DOTATOC PET/CT in neuroendocrine tumors
Introduction: In the absence of preoperative somatostatin receptor (sst) scans, knowledge of immunohistochemical sst2 tumor expression may help in predicting the success of somatostatin analogue-based follow-up studies and treatment of neuroendocrine tumors (NETs).

#447 SOMscan: Towards a Ga-68-labeled Pan-Somatostatin PET Imaging Probe Based on SOM230 (Pasireotide)
Introduction: The somatostatin receptor subtype sst2 is largely expressed on neuroendocrine tumors. However, current clinical studies indicate that the subtypes sst1, 3, 5 are of substantial relevance as well.

#586 A Single-Center, Open-Label, Phase II, Proof-of-Concept Study with Pasireotide LAR in patients with progressive medullary thyroid cancer (MTC): preliminary data
Introduction: MTC is a well-differentiated neuroendocrine tumor in which somatostatin receptor (sst) expression is higher for sst1 and sst5 than for sst2.
