Octreotide Scan Tell your doctor if you are pregnant or breastfeeding. You have scheduled an Octreotide™ study. This study uses a small amount of radioactive material. The level of radioactivity used is extremely low and has no side effects. How do I prepare for my study? • Discontinue taking Somatostatin® 24-48 hours before injection. Discontinue radiation therapy. • Notify your physician if you have a cold or the flu. What will happen during my study? This is a 2 part study. Part 1: We will inject a small amount of radioactive material into a vein in your arm. Part 2 (24 hours later): • We will position you on an imaging table, under a special detector called a gamma camera. The camera will be close to the part of your body being imaged. The camera does not produce any radiation and will not cause any pain or discomfort. • You may also receive a CT scan as part of the imaging procedure to help your doctors read the study. • Sometimes additional imaging is required 48 hours after the injection.

Recent Advances in Radiological and Radionuclide Imaging and Therapy
European Journal of Endocrinology (2004) 151 15–27 ISSN 0804-4643 REVIEW Recent advances in radiological and radionuclide imaging and therapy of neuroendocrine tumours Gregory Kaltsas, Andrea Rockall1, Dimitrios Papadogias, Rodney Reznek1 and Ashley B Grossman Departments of Endocrinology and 1Academic Radiology, St Bartholomew’s Hospital, London ECIA 7BE, UK (Correspondence should be addressed to Ashley B Grossman, Department of Endocrinology, St Bartholomew’s Hospital, London EC1A 7BE, UK; Email: [email protected]) Abstract Neuroendocrine tumours (NETs) constitute a heterogeneous group of tumours that are able to express cell membrane neuroamine uptake mechanisms and/or specific receptors, such as somatostatin receptors, which can be of great value in the localization and treatment of these tumours. Scintigra- phy with 111In-pentetreotide has become one of the most important imaging investigations in the initial identification and staging of gastro-enteropancreatic (GEP) tumours, whereas helical computed tomography (CT), magnetic resonance imaging (MRI), endoscopic and/or peri-operative ultrason- ography are used for the precise localization of GEPs and in monitoring their response to treatment. Scintigraphy with 123I-MIBG (meta-iodobenzylguanidine) is sensitive in the identification of chromaf- fin cell tumours, although scintigraphy with 111In-pentetreotide may also have a role in the localiz- ation of malignant chromaffin cell tumours and medullary thyroid carcinoma; for further localization and monitoring of the response to treatment both CT and MRI are used with high diagnostic accu- racy. More recently, positron emission tomography (PET) scanning is being increasingly used for the localization of NETs, particularly when other imaging modalities have failed, although its precise role and utility remain to be defined.

The 2010 Gastrointestinal Cancers Symposium General Session IV: Prevention, Screening and Diagnosis
The 2010 Gastrointestinal Cancers Symposium General Session IV: Prevention, Screening and Diagnosis Abstract #125: The role of octreotide imaging in detecting neuroendocrine tumors (NETS) in 2010: Do we still need it? Speaker: Diane Reidy‐Lagunes, MD – Memorial Sloan Kettering Cancer Center Introduction • The goal of the presentation is to understand the relative utility of CT or MRI (morphologic imaging) and octreotide scan (functional imaging) to detect disease in patients with neuroendocrine tumors. • Many patients in the preoperative/postoperative metastatic setting are actually getting both of these imaging modalities and it is unclear if there is an incremental benefit of using both modalities in detecting neuroendocrine tumors. Background – Neuroendocrine Tumors and Octreotide • Neuroendocrine tumors (NETs) are uncommon tumors that express the neuroendocrine markers synaptophysin and chromogranin. • Per SEER data presented by Dr. Yao the incidence of NETs is increasing. Their prevalence is also increasing as patients live longer with the disease. • Well differentiated NETs typically express somatostatin receptors. • Octreotide is an eight amino analogue of the 14‐amino acid regulatory hormone somatostatin. It binds to tumor cells that have predominantly type 2, 3, 5 somatostatin receptors (SSRT). Octreotide Scan (aka OctreoScanTM) – Background • A diagnostic nuclear medicine imaging modality utilizing an octreotide molecule linked via a chelator to Indium. • Injected and binds to predominantly SSRT 2, 3, 5 when delivered to the cell surface. • Radioactivity is internalized into the cell via endocytosis and a gamma camera takes pictures of tumors to evaluate extent of disease. Comparison of Radiation Exposure and Cost • An Octreotide scan’s radiation exposure is similar to that of a CT scan.

Some examination methods into account the radiation such as X-ray or nuclear medical diagnostics involve ionising radiation or doses, are available to the radioactive substances.

Therefore the Recommendations for medical exposure as low as possible. There is constant enhancement of imaging procedures address first of all physicians referring patients for diagnostic procedures and therefore these recommendations are further diagnostics. The goal is to avoid unnecessary radiation exposure reviewed and updated on a regular basis. while achieving the same level of diagnostic accuracy.

Octreotide Uptake in Parathyroid Adenoma Paratiroid Adenomunda Oktreotid Tutulumu

There was no focal pathologic tracer uptake, but generalized marked increase in skeletal uptake on bone scintigraphy. Octreotide scintigraphy showed accumulation of octreotide in the region of the left lobe of the thyroid gland in the neck. Thereafter, parathyroid scintigraphy was performed with technetium-99m labeled metroxy-isobutyl-isonitryl (99mTc-MIB) and MIBI scan demonstrated radiotracer uptake at the same location with octreotide scintigraphy. The patient underwent left inferior parathyroidectomy and histopathology confirmed a parathyroid adenoma. Somatostatin receptor positive parathyroid adenoma may show octreotide uptake. Octreotide scintigraphy may be promising and indicate a possibility of using somatostatin analogues for the medical treatment of somatostatin receptor positive parathyroid tumors.
