Abstract:

Purpose: The aim of this observational cross-sectional study with retrospective review of the data is to evaluate the efficacy of using Technetium-99m - Octreotide in imaging Neuroendocrine tumors (NETs).Materials and
Methods:
A total of 58 patients with Technetium-99m -Octreotide (Tc-99m- OCT) were identified in our database, from January 2013 until December 2016. 41 patients (age range of 15-75 year) meet our inclusion criteria namely; histopathology proven neuroendocrine tumors, Technetium-99m -Octreotide scan, CT, MRI or both done in our institute for correlation.Results: 23 patients had true positive Tc-99m– OCT scan. In addition to the primary tumors the Octeriotide scan revealed metastasis in the lung, liver and retroperitoneal lymph nodes. The smallest lesion detected on Octreotide scan was a 4-mm pulmonary nodule, that was missed on lung window CT scan. The Tc-99m– OCT had 17 true negative, one false negative and no false positive. The CT and MRI scans had 18 true positive, 17 true negative, 5 false negative and one false positive. The overall sensitivity, specificity, accuracy, positive and negative predictive values of Tc-99m– OCT scan were; 96%, 100%, 97%, 100% and 94% respectively. Whereas those of CT and MRI were; 78%, 94%, 85%, 94% and 77%, respectively.Conclusion: The overall diagnostic accuracy of Technetium-99m-Octreotide is high. In addition to the conventional radiological investigations, Tc-99m-OCT scan is a mandate for better and accurate staging of patients with NETs.
