The Correlation between 68Ga-DOTATATE PET/CT Results and Tumor Proliferation in Patients with Gastroenteropancreatic Neuroendocrine Neoplasms (GEP-NENs) Abstract #2048

Introduction: GEP-NENs are heterogeneous neoplasms characterized by overexpression of somatostatin receptors (SSTRs). PET/CT with 68Ga-DOTATATE has shown excellent results for imaging of NENs and has been used more and more widely.
Aim(s): Analyze the correlation between 68Ga-DOTATATE results and biological characters of GEP-NENs. Explore the cut-off value of SUVmax to differentiate NET and NEC.
Materials and methods: 126 non-functional GEP-NENs cases were enrolled. All the patients had pathologically proven primary and/or metastasis. Images were acquired 1h post injection of 100–200 MBq 68Ga-DOTATATE. The highest SUVmax of lesions generated from each patient was used in analysis.

#9 Case Management of Metastatic carcinoid of the Foregut,Midgut and Hindgut:the relevance of Ki-67 prognostication
Introduction: The predictive value of tumor grade in the prognosis of carcinoid is insufficient and somehow misleading. The grade and differentiation in carcinoid tumors must be seen in conjunction with the Ki-67 index. The Ki-67 protein is a cellular marker for proliferation, present during all active phases of the cell cycle (G1, S, G2 and mitosis) and absent from resting cells (G0). It is therefore an excellent marker to determine the growth fraction of a given cell population. The Ki-67 labelling index is often correlated with the clinical course of carcinoid.

#11 Plasma chromogranin - A response to octreotide test: Prognostic value for clinical outcome in endocrine digestive tumors
Introduction: Gastroenteropancreatic neuroendocrine tumors (GEP-NETs) expressing somatostatin receptors may be treated with somatostatin analogues (SSAs). Selection criteria are a positive Octreoscan® or a >50% hormone level decrease after octreotide s.c. injection (octreotide test) (OT). Plasma chromogranin A (CgA) is the best general GEP-NET marker, but data on CgA response to OT are scant.

#12 Chromogranin A as a predictor of progression, regression or stable disease in ileo-cecal (midgut) carcinoid tumors
Introduction: A general characteristic for NETs is their expression of certain proteins, such as chromogranin A (CgA), which is released from the dense core vesicles of NE cells, occasionally together with cell specific hormones, such as gastrin and serotonin. Plasma CgA seems to be closely related to tumor burden of intestinal carcinoid tumors in humans.

#13 Neoadjuvant peptide receptor radionuclide therapy for an inoperable neuroendocrine pancreatic carcinoma
Introduction: Pancreatic endocrine tumors (pNETs) are rare but are among the most common neuroendocrine neoplasms of the abdomen. At diagnosis, many of them are already advanced and difficult to treat.

#14 Radioguided surgery in NET: First impression with Ga-68 labeled somatostatin analogues
Introduction: Neuroendocrine tumors (NET) constitute a heterogenous group of neoplasms. The development of Gallium-68-labeled somatostatin analogues, such as DOTA-NOC or DOTA-TOC, PET/CT have dramatically improved the diagnosis of neuroendocrine tumors. Surgery remains the treatment of choice for localized disease as well as metastatic disease. The aims of surgery are: improvement of symptoms, reduction of tumor mass / burden and to give better quality of life to patients. Recurrent laparotomies often lead to multiple adhesions and altered anatomy. So it is increasingly difficult for imaging physicians and surgeons to separate non-malignant from malignant tissue.
