#3035 Large-Cell Neuroendocrine Carcinoma of the Lung in Elderly Patient: Case Report and Review of Literature
Introduction: Lung neuroendocrine tumors account for less than 25% of lung cancers.Which is a rare malignant tumor with an aggressive profile has often already affected lymph nodes at presentation and it is de novo metastatic in nearly 40% of cases.

#22 A Case Illustrative of Phenotypic Heterogeneity and Challenges in the Management of Paraganglioma
Introduction: Paragangliomas (PGLs) are extra-adrenal, usually benign, highly vascularized tumors that originate from neural-crest-derived chromaffin cells. These tumors are subdivided as either sympathetic or parasympathetic, depending on their location and catecholamine production. Sympathetic PGLs are situated along the abdominal sympathetic trunk and usually produce catecholamines, whereas parasympathetic PGLs are located in the head and neck, and these usually do not produce catecholamines. PGLs may present as sporadic or inherited tumor syndrome, including MEN 2, with RET germline mutations, von Hippel-Lindau (VHL) disease due to germline mutations in VHL gene, and pheochromocytoma-PGL syndrome. The latter is frequently a hereditary condition and is caused by germline mutations in the SDHB, SDHC, or SDHC genes. Patients with familial PGLs may present at a younger age, often as multifocal tumors, with an increased risk of recurrence and a higher frequency of malignancy in those with SDHB mutations. SDH mutations induce angiogenesis and tumorogenesis through the inhibition of hypoxia-inducible factors (HIF)-propyl hyroxylase. A younger age at onset, malignancy, and a positive family history are clinical parameters of high specificity, but low sensitivity for diagnosis. Genetic analysis for mutations in SDH genes for the patient and family members, and surveillance for the affected patient and family members, are necessary where there are no clear clinical or family indicators for the syndrome. We present a case of a large abdominal malignant PGL in a 20-year-old pt. that went on without clinical detection for at least three years.

#453 Activation of Hedgehog Pathway in Neuroendocrine Tumor
Introduction: Neuroendocrine tumors (NETs) are rare tumors and often follow an indolent course, especially the tumors of low-to-intermediate grade. The genetic etiology of sporadic NET is largely unknown. It is well-known that a significant number of patients with NETs may have harbored the slow-growing lesions since very a young age, suggesting it could result from alterations of pathways involved in development. Hedgehog (Hh) signaling has been found to be important in embryonic patterning, stem cell maintenance and tissue repair; and is normally silenced in most mature adult tissue. However, it frequently undergoes gain-of-function mutations or reactivation due to ligand overproduction and has been linked to the etiology of a variety of tumors.

#1564 Well Differentiated Pancreatic Neuroendocrine Tumors (WDPNET) G3: Does the Ki67 Really Do It All?
Introduction: WDPNET G3, although not recognized by the 2010 WHO classification are far from exceptional. They also represent a great therapeutic challenge especially since their molecular drivers are unknown.

#2113 How to Perform Contrast Enhanced Oncologic Staging MRI of Abdomen and Pelvis with a Hepatocyte Specific Agent in a Large Bore MR Scanner: Optimizing Extrahepatic Tumor Evaluation in Neuroendocrine Neoplasms
Introduction: Liver specific MR contrast agents in neuroendocrine neoplasms (NEN) have shown its advantages in evaluation of hepatic tumor burden. However, a standard scan protocol is insufficient in extrahepatic and especially pelvic tumor evaluation.

#3089 Mixed Large and Small Cell Neuroendocrine Carcinoma of the Endometrium: A Case Report and Literature Review
Introduction: Neuroendocrine carcinoma (NEC) is an extremely rare subtype of endometrial cancer which is usually seen among perimenopausal or postmenopausal women. It runs an aggressive course and posts a clinical challenge due to limited treatment options available.

#2866 Extrahepatic 68Ga-DOTATATE-Avid Tumor Volume and Serum Chromogranin A Predict Short-Term Outcome of 177Lu-DOTATATE in Late-Stage Metastatic Gastroenteropancreatic Neuroendocrine Tumors
Introduction: 177Lu-DOTATATE is an effective therapy for somatostatin receptor-positive neuroendocrine tumors (NETs). Often enough 177Lu-DOTATATE is used as the last treatment resort in advanced NET.
