SOMATOSTATIN RECEPTORS SCINTIGRAPHY PRIORITIZATION CRITERIA BASED ON NET PATIENT EPIDEMIOLOGICAL PROFILE: A BI-CENTRIC STUDY

This study aimed to create a generic profile of patients with NETs and to establish the prioritization criteria for somatostatin receptors scintigraphy (SRS), within the NETs diagnostic algorithm, being the first study of this kind conducted in Romania. Material and methods: A bi-centric, retro-prospective study comprising 103 patients with NETs, evaluated through 99mTc-TOC SRS, in two nuclear medicine departments from “Sf. Spiridon” County Clinical Emergency Hospital Iasi, Romania and Center of Nuclear Medicine, University Clinical Center of Kragujevac, Serbia. We analyzed the clinical-paraclinical features of included patients, as a starting point for streamlining the selection of patients for SRS. Results and discussion: The total group of patients included 47.57 % men and 52.43 % women, the age varying between 21-83 years. The most frequent primary NETs were represented by pNETs, and GI-NETs and the symptoms were nonspecific for majority of analyzed patients. Both prospective and retrospective analysis showed that SRS was followed by positive results. For prospectively analyzed patients, due to the used customized sheets, it was extremely easy to identify four SRS prioritization criteria. Conclusions: This study could outline the profile of patients with NETs, as the starting point for streamlining patient selection for SRS. The four prioritization criteria proposed by us could guide the diagnostic algorithm.
