#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.

#28 Prognostic Clinicopathologic Factors in Longitudinally Followed Patients with Metastatic Small Bowel Carcinoid
Introduction: Neuroendocrine tumors demonstrate heterogeneous behavior based upon site of origin and specific histology. Even after controlling for anatomic location, disease stage and histologic grade, registry studies show persistent diversity of outcome in patients with midgut carcinoid.

#231 Chromogranin A as a Predictor of Progression, Regression or Stable Disease in Ileo-Cecal Neuroendocrine Tumors
Introduction: Chromogranin A is an excellent marker for NET and tumor volume. Plasma CgA is suggested as the most reliable marker in follow-up of patients with some types of NET.

#670 The Relationship Between the Ki-67 Protein and IGF-Related Genes in Gastroenteropancreatic Neuroendocrine Tumor Patients with Normal and Elevated Serum Chromogranin-A
Introduction: GEP-NETs are rare, heterogeneous neoplasms with a distinct biological and clinical behavior. Both IGF-system and Ki-67 indices have been reported as important stimulating factors in carcinogenesis and/or tumor progression. The tumor marker CgA is an independent predictor for survival as well. Currently no data are available about a possible interaction between IGF-system (IGF(-R)s, IRs, BPs) and Ki-67 protein in GEP-NET patients with normal and elevated serum CgA.

#117 Synchronous appendiceal neuroendocrine carcinoma and mucinous cystadenocarcinoma: a case report
Introduction: Appendiceal tumors with histological features of both carcinoids and adenocarcinomas are very rare. Carcinomas of the appendix are usually mucinous adenocarcinomas with a tendency to produce peritoneal pseudomyxoma and without metastatic spread until late in the disease course. Carcinoid tumors of the appendix are a common incidental finding.

#1592 Primary Neuroendocrine Carcinoma of the Breast: A Diagnostic Approach to the Special Type of Breast Malignancy
Introduction: WHO classification from 2003 defines primary neuroendocrine carcinomas (NEC) of the breast as a group of tumors with expression of neuroendocrine markers in more than 50% of tumor cells. In the current WHO classification this category is renamed to “carcinomas with neuroendocrine features” without defined clear-cut of the percentage of tumor cells positive for neuroendocrine markers.

#146 Recurrence characteristics in resected pulmonary typical and atypical carcinoids
Introduction: Pulmonary typical and atypical carcinoids are widely considered indolent, although they can metastasize even with a very long relapse free interval. No standard follow-up strategy exists after a radical resection.

#248 Difficulties in Differential Diagnostics of Neuroendocrine Tumors
Introduction: Primary neuroendocrine tumors (NET) of soft tissues and soft tissue metastases are seen rarely and need differentiation from other types of tumors (as chemodecroma or paraganglioma).

#255 The Carcinoid Syndrome Caused by Retroperitoneal Carcinoid Tumors
Introduction: The carcinoid syndrome is caused by increased levels of serotonin and is mostly seen in cases of carcinoid tumor in the small bowel and liver metastases, as there is a very high first pass effect.

#489 Goblet Cell Appendiceal Neuroendocrine Tumors: Diagnosis, Recurrence Rates, Treatment and Survival. A Series of 37 Patients
Introduction: Goblet cell appendiceal neuroendocrine tumors (GCA-NETs) share histologic features of both adenocarcinomas and NETs.
