TEP With 68-DOTANOC in Gastroenteropancreatic Neuroendocrine Tumors (68-DOTANOC-GEP)

This study has been completed.
Information provided by (Responsible Party):
Nantes University Hospital Identifier:
First received: November 13, 2012
Last updated: July 28, 2016
Last verified: July 2016

Evaluation of the diagnostic performance of PET / CT with 68Ga-DOTANOC in Gastroenteropancreatic Neuroendocrine Tumors with comparison with other techniques used in routine clinical practice (octreoscan ® ; multiphase SPECT / CT, MRI or endoscopy).

Therapeutic impact and safety of PET / CT with 68Ga-DOTANOC will also be assessed. Expected results are a confirmation of the superiority of 68Ga-PET DOTANOC versus scintigraphy octreoscan ®, with a potential impact on the therapeutic management of patients.

Condition Intervention
Patients With Gastroenteropancreatic Neuroendocrine Tumors Drug: 68-Ga-DOTANOC

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Diagnostic
Official Title: Diagnostic, Prospective, Comparative, Multicentric Study of the PET / CT With 68Ga-DOTANOC Versus Conventional Imaging Procedures (octréoscan ® Scintigraphy and CT / MRI) in the Assessment of in Gastroenteropancreatic Neuroendocrine Tumors

Further study details as provided by Nantes University Hospital:

Primary Outcome Measures:
  • Detection of Gastroenteropancreatic Neuroendocrine Tumors lesions in the initial assessment or during the search of recurrence. [ Time Frame: 12 months ]
    Reference to the gold standard (that will be obtained from the data of histology and / or follow-up imaging at least 12 months

Secondary Outcome Measures:
  • Compare the diagnostic performance of PET / CT with 68Ga-DOTANOC with the standard process [ Time Frame: 12 months ]

Other Outcome Measures:
  • Assess the clinical impact of PET / CT 68 Ga-DOTANOC in terms of specificity and predictive value for the detection of locations of GEP. [ Time Frame: 12 months ]
  • Assess the relevance of decisions of PET / CT 68 Ga-DOTANOC in terms of specificity and predictive value for the detection of locations of GEP. [ Time Frame: 12 months ]
  • Assess the value of PET / CT 68 Ga-DOTANOC in terms of specificity and predictive value for the detection of locations of GEP. [ Time Frame: 12 months ]
  • Tolerance of 68-Ga-DOTANOC [ Time Frame: 12 mois ]
    the vital signs and clinical tolerance will be assess during the 2 hours following injection of the radiopharmaceutical.

Estimated Enrollment: 130
Study Start Date: November 2012
Study Completion Date: May 2016
Primary Completion Date: May 2016 (Final data collection date for primary outcome measure)

Ages Eligible for Study:   18 Years and older   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Age over 18 years
  • effective contraception or exclusion of pregnancy dosage of beta-HCG in women of childbearing age
  • Fortuitous discovery of suggestive tumors of TE-GEP with well documented conventional imaging (multiphase CT; MRI, US endoscopy) associated or not associated with clinical or biological signs of TE-GEP tumors (increase in tumor markers) OR
  • Histologically proven GEP-TE (WHO classification 2010 (26) well differentiated in the initial staging OR
  • Suspicion of recurrence or progression of well differentiated TE-GEP tumors on conventional imaging or laboratory tests (increase in tumor markers) OR
  • Clinical or biological syndrome strongly suggestive of digestive endocrine disease without identification of lesions with conventional imaging
  • Informed consent and patient's written
  • Affiliation to an insurance

Exclusion Criteria:

  • Multiple endocrine neoplasia
  • TE GEP tumor not differentiated
  • Pregnancy and lactation
  • Persons protected by law
  • Restlessness, inability to lie still hold at least 1 hour; Claustrophobia
  • Poor compliance predictable or inability to undergo medical test for geographical, social or psychological
  • Treatment with radiotherapy, chemotherapy or other antitumor treatment within 6 weeks of previous morphological and scintigraphic examinations. In case of treatment with somatostatin analogues delayed, scans will be performed 4 weeks after the last injection. However, a shorter period may be observed to avoid to do again the initial assessment exams.
  • malignancy except basal cell cancers and cancer in situ of the cervix
  • Contraindication of injection of a contrast agent necessary for the production of multiphase scanner.
  • Patients who had a CT scan without injection of contrast material can not participate in the study
