Latest News
Summary
- This summary is based on the review of three systematic review(s)/meta-analysis(es). [1-3]
- Imaging Uptake and Tumor-to-Background Ratios: In patients with neuroendocrine tumors (NETs), the uptake of Gallium-68-labeled DOTATATE showed no significant change at primary and metastatic sites following somatostatin analog (SSA) therapy, though the tumor-to-liver/background ratio increased post-treatment.
- True Positivity Rates: Radiolabeled peptides varied in true positivity rates, with (111)In-DTPA-Octreotide at 63.7%, (99m)Tc-EDDA/HYNIC-TOC at 58.5%, (68)Ga-DOTATATE/TOC at 78.4%, and (64)Cu-DOTATATE at 82.4%; PET tracers (68)Ga-DOTATATE/TOC and (64)Cu-DOTATATE demonstrated higher rates than SPECT (single photon computed emission tomography) agents.
- Diagnostic Performance for Pancreatic NETs: The sensitivity and specificity of (68)Ga-DOTATATE in SSR-PET/CT imaging for primary pancreatic NETs (pNETs) were 79.6% and 95%, respectively, with pooled detection rates of 81% for patient-based and 92% for lesion-based analysis.
- There is no safety information available in the reviewed studies.
- There is no population types or subgroups information available in the reviewed studies.
