  Purpose
This protocol is designed to test the efficacy of 68Ga-DOTATOC PET/CT in diagnosis, staging, and measurement of response to treatment in patients with somatostatin receptor positive tumors. Goals are to 1) compare this unique PET/CT scan with the current standard of care which is a combination of Octreoscan SPECT (single photon emission tomography) plus a high resolution, contrast enhanced CT; 2) Determine the sensitivity of 68Ga-DOTATOC PET/CT in diagnosis of patients with suspected somatostatin receptor positive tumor; and 3) For those patients who have had recent treatment (e.g., surgery, chemotherapy, targeted therapy such as anti-angiogenics, kinase inhibitors, peptide receptor radiotherapy), this scan will be used to measure response to treatment. These studies will be obtained with the long term goal of submitting a New Drug Application (NDA) for FDA approval of 68Ga-DOTATOC PET/CT in adults and children.

Condition Intervention
Neuroendocrine Tumors Carcinoid Tumors Neuroblastoma Medulloblastoma Drug: 68Ga-DOTATOC PET/C

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: Double (Investigator, Outcomes Assessor)
Masking Description:
The Octreoscan and 68Ga-DOTA-tyr3-Octreotide PET scans are read independently by two certified nuclear medicine physicians for discordant positive lesions.
Primary Purpose: Diagnostic
Official Title: Safety & Efficacy of 68Ga-DOTA-tyr3-Octreotide PET/CT in Diagnosis, Staging & Measurement of Response to Treatment in Patients With Somatostatin Receptor Positive Tumors: Comparison to Octreoscan Plus High-Resolution, Contrast Enhanced CT.

Primary Outcome Measures:
  • This protocol is designed to test the efficacy of 68Ga-DOTATOC PET/CT in diagnosis, staging, and measurement of response to treatment in patients with somatostatin receptor positive tumors. [ Time Frame: 1 week to 6 months ]
    We will 1) compare this unique PET/CT scan with the current standard of care which is a combination of Octreoscan SPECT (single photon emission tomography) plus a high resolution, contrast enhanced CT; 2) Determine the sensitivity of 68Ga-DOTATOC PET/CT in diagnosis of patients with suspected somatostatin receptor positive tumor; and 3) For those patients who have had recent treatment after the initial PET/CT scan (e.g., surgery, chemotherapy, targeted therapy such as anti-angiogenics, kinase inhibitors, peptide receptor radiotherapy), we will measure response to treatment.

Ages Eligible for Study:   2 Years and older   (Child, Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  • Signed informed consent
  • Age greater than or equal to 2 years
  • Known or suspected somatostatin receptor positive tumor such as carcinoid; neuroendocrine tumor; neuroblastoma; medulloblastoma; pheochromocytoma. Supporting evidence may include MRI, CT, biochemical markers, and or pathology report.
  • Karnofsky performance status or Lansky Play Scale status of greater than 50 (or ECOG/WHO equivalent)
  • Subject is male; or is a female who is either pre-menarchal, surgically sterile (has had a documented bilateral oophorectomy and/or documented hysterectomy), postmenopausal (> 1 years without menses), non-lactating, or of childbearing potential for whom a serum pregnancy test (with the results known prior to investigational product administration) is negative. A negative serum pregnancy test will be required for all female subjects with child bearing potential. If a false pregnancy test is suspected, e.g., perimenopausal condition, an obstetrician will be consulted to determine if she is/is capable of becoming pregnant.

Exclusion Criteria:

  • Subject weighs more than 400 pounds (Subjects who weigh more than 400 pounds will not be able to fit inside the imaging machines).
  • Inability to lie still for the entire imaging time (e.g. cough, severe arthritis, etc.)
  • Inability to complete the needed investigational and standard-of-care imaging examinations due to other reasons (severe claustrophobia, radiation phobia, etc.)
  • Does the subject have any additional medical condition, serious intercurrent illness, or other extenuating circumstance that, in the opinion of the Investigator, may significantly interfere with study compliance?
