- Abstract
Simple Summary: Neuroendocrine neoplasms' (NENs) rarity and heterogeneity represent a clinical challenge. Somatostatin receptor (SST) positron emission tomography/computed tomography (PET/CT) availability and different reimbursement policies across countries account for its heterogenous employment on a single-case basis. The aim of this study was to prospectively collect data of the real-life use of and indications for [68Ga-DOTA0-1NaI3]octreotide ([68Ga]Ga-DOTANOC) PET/CT in a prospective 5-year electronic archive at a single center. Overall, more than 2000 scans were included. This systematic data collection in a high-volume diagnostic center represents a reliable cohort reflecting the trends of [68Ga]Ga-DOTANOC PET/CT use across different clinical indications and primary tumor sites. The recent introduction of novel treatments for advanced neuroendocrine tumors (NETs) and the well-established impact of clinical case discussion within dedicated multidisciplinary teams indicates the need to promote the centralization of rare diseases, such as NENs (neuroendocrine neoplasms). Data on the real-life use of and indications for [68Ga]Ga-DOTANOC PET/CT were collected from a prospective monocentric 5-year electronic archive including consecutive patients with confirmed and suspected NETs (September 2017 to May 2022). Overall, 2082 [68Ga]Ga-DOTANOC PET/CT scans (1685 confirmed NETs, 397 suspected NETs) were performed in 1537 patients. A high positivity rate was observed across different clinical settings (approximately 70%). Approximately 910/2082 scans were requested by the local oncology ward (851 confirmed NETs, 59 suspected NETs). The following observations were found: (i) the detection rate across all indications was 73.2% (higher for staging, peptide receptor radioligand therapy (PRRT) selection, and treatment response assessment); (ii) in suspected NETs, PET was more often positive when based on radiological findings. This systematic data collection in a high-volume diagnostic center represents a reliable cohort reflecting the global trends in the use of [68Ga]Ga-DOTANOC PET/CT for different clinical indications and primary tumor sites, but prompts the need for further multicenter data sharing in such a rare and slowly progressive disease setting.
