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.
