    Scientific background

    Somatostatin is a small cyclic peptide that is widely expressed throughout the central nervous system and peripheral tissues1. In peripheral tissues, somatostatin exerts inhibitory effects on secretion processes, whereas in the brain, it acts as a neurotransmitter in both a stimulatory and an inhibitory manner1,2.

    Somatostatin mediates its action via six high affinity G-protein coupled receptors (SSTR1, SSTR2a, SSTR2b, SSTR3SSTR4, and SSTR5), which are encoded by five genes1,2. Expression of the different receptors is developmentally regulated in a time- and tissue-specific manner2.

    Somatostatin receptors have been found on a variety of neuroendocrine tumors, such as paragangliomas, carcinoids, and breast tumors3. Synthetic peptide derivatives of somatostatin have been successfully used in the treatment of neuroendocrine malignancies and in vivo imaging of tumors that are positive for somatostatin receptors4.

    In general, SSTR2 is the most common SSTR subtype found in human tumors, followed by SSTR1, with SSTR3 and SSTR4 being less common.
