Validation of 99mTc- EDDA - HYNIC -TOC Kits for Diagnosis of Neuroendocrine Tumors

February 3, 2025 updated by: Latin American Cooperative Oncology Group
Evaluation of the properties of the image capture test using 99m Tc - HYNIC -TOC EDDA (octreotide labeled with 99mTc) for the diagnosis of neuroendocrine tumors compared to the 111In - DTPA-octreotide.

  • Allocation: N/A
  • Interventional Model: Single Group Assignment
  • Masking: None (Open Label)

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Adult patients with neuroendocrine tumors
Other: 99m Tc - HYNIC -TOC EDDA and 111In - DTPA-octreotide
The patient will undercome an PET/CT exam with 99m Tc - HYNIC -TOC EDDA, after 20 days of wash out, the same patient will undercome the same exam with 111In - DTPA-octreotide in order to compare both radiopharmaceuticals
