Simultanenous Duplicate Malignant Disease-Adenocarcinoma of the Colon and Disseminated Neuroendocrine Tumor Abstract #884

Introduction: Fifty-nine-year old man, under examination due to weight loss, enterorrhagia, general abdominal discomfort. Endoscopy detected tumorous infiltration 20 cm from the anus, bleeding. Histology: adenocarcinoma. CT abdomen detected liver lesion. The lesion was hypervascularized, and the CT picture was atypical for metastatic adenocarcinoma. CT chest: tumor lesion in the left lower segment, metastatic LN in mediastinum. According to the CT, the picture is atypical for metastases.
Aim(s): Bronchoscopy: tumorous granulations in the region of B 10 left, histology: neuroendocrine tumor. Scintigraphy of the skelet: pathological cumulation in the ribs and chest backbone. Tumor markers within normal levels.
Materials and methods: Because of the unclear finding in the liver and patient's symptoms, resection of sigmoid tumor and liver revision was done. In the liver, multiple lesions were found and resected. Histology from sigmoid tumor: adenocarcinoma . Histology from liver metastases: neuroendocrine tumor GR 1. Octeoscan: multiple lesions of high activity found in liver, lungs, skelet. The level of CrA was 275.

#21 Peptide Receptor Radioligand Therapy (PRRT) is an Effective Treatment for the Long-Term Stabilization of Malignant Gastrinomas
Introduction: Gastrinomas represent a rare group of neuroendocrine tumors usually located in the duodenum or pancreas. They secrete gastrin, which is responsible for the clinical picture of severe acid-related peptic disease and diarrhea, known as the Zollinger-Ellison syndrome (ZES). While symptomatic control may be achieved with proton-pump inhibitors (PPIs) and somatostatin analogues (SSAs) treatment, little data is known regarding the possible anti-tumor effect of the peptide receptor radioligand therapy (PRRT) in gastrinoma patients.

#142 The role of 18F DOPA-PET in a case of malignant pheochromcytoma
Introduction: Pheocromocytoma is a rare tumor arising from chromaffin cells of adrenal medullary or extra adrenal paraganglionic tissue. Histological criteria cannot differentiate benign from malignant pheocromocytomas. The diagnosis of a malignant pheocromocytoma requires local invasion, recurrence and documented metastatic disease. The radionuclide scanning (123I - 131I-MIBG) is a fundamental diagnostic tool used to confirm the biochemical and radiological diagnosis of pheochromocytoma. In fact, MIBG scanning may confirm that the visualised lesion in an adrenal gland is indeed a pheochromocytoma and detect extra-adrenal paraganglionic tissue. However, MIBG scans are negative in around 15% of benign pheochromocytomas and in up to 50% of malignant ones. Other radionuclide techniques (18FDG-PET, 18F-DOPA-PET, 18F-FDA-PET) have been successfully used in investigation of pheochromocytomas. 18F-DOPA-PET and 18F-FDA-PET have been reported to be highly sensitive and specific for benign pheochromocytomas, while 18FDG-PET can be useful for malignant lesions with higher metabolic activity.

#416 A Rare Case of Cushing Syndrome Caused by an Ectopic ACTH-Secreting Pancreatic Neuroendocrine Tumor in a Patient with Von Hipple-Lindau Disease
Introduction: Von Hipple-Lindau (VHL) disease is a rare autosomal dominant disorder, that causes the susceptibility to various tumors, both benign and malignant. The most frequent tumors are central nervous system haemangioblastomas, especially cerebellum and retinal haemangioblastomas, renal cell carcinoma /renal cysts and pheocromocytoma.

#177 Dissociation Between Iodine-131 meta-iodobenzylguanidine (MIBG) Scintigraphy and Radiolabeled Octreotide in the Localization and Management of Sporadic Malignant Pheochromocytoma: An Impact on Management
Introduction: The Rx of malignant pheochromocytomas w/negative MIBG scan remains a challanging problem. Octreoscan is helpful in localization and Rx planning in such cases. Rx using SST analog & PRRT is a desirable goal.

#640 Chomogranin A, NSE, and 5-Hydroxyindolacetic Acid Measurements in Malignant Carcinoids
Introduction: GEP-NETs are a heterogeneous group of cancers more common in the small intestine which are usually asymptomatic. In patients with malignant carcinoids, a number of tumor markers (TMs) have been considered enclosing urinary 5-hydroxyindolacetic acid (5-HIAA), chromogranin A (CgA), and neuron-specific enolase (NSE) serum levels measurements. Unfortunately, the sensitivity of each TM largely depends on disease extent and the presence of functioning tumors, and thus their usefulness is still unclear.
