Clinical Trial Summary

To evaluate the concordance and discordance between results of 68Ga-DOTATATE PET-CT scan and OctreoScan ® which is considered standard of care diagnostic test for neuroendocrine cancers and other imaging modalities like CT scan/MRI as gold standard.

Description:

The number of lesions that could be identified clearly as single foci will be determined for each patient. The same anatomic areas will be imaged with 68Ga-DOTATATE PET and 111In-penteoctreotide Scintigraphy to ensure relevant comparison of lesion detection. Because of confluence and inability to clearly delineate single liver lesions in some cases, liver metastases will be classified as 1 organ metastasis, independent of the number of liver metastases present. Lymph nodes smaller than 1 cm on CT or MRI and showing marked avidity for 68Ga- DOTATATE and 111In-penteoctreotide will be labeled as positive for disease. The presence of lesions will be confirmed by cross-sectional imaging of all patients with CT or MRI.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Number of lesions detected by 68GA-DOTATATE compared to conventional imaging technique	We want to determine if the 68Ga-DOTATATE PET/CT scan changes care plans compared to conventional imaging/diagnostic techniques (Octreoscan, MRI).	SOT within 28 days before 68Ga-DOTATATE PET/CT scan
Secondary	Frequency and severity of Adverse Events	Adverse events will be collected from the time of 68Ga-DOTATATE injection until 48 hours post-injection visit. Adverse events will be classified using criteria for adverse events (CTCAE) Version 4.	4 days
