#1544 Immunohistochemical Expression of Estrogen and Progesterone Receptors in Neuroendocrine Tumors
Introduction: Expression of progesterone (PR) and estrogen receptor (ER) in some neuroendocrine tumors (NET) raises the possibility of hormonal regulation in these tumors, but those prevalence and clinical implication are unknown.

#2712 HORMONET: Study of Tamoxifen in Well Differentiated Neuroendocrine Tumors (NET) and Hormone Receptor Positive Expression
Introduction: We have shown immunohistochemistry (IHC) expression of estrogen (ER) and progesterone receptors (PR) in 20.8% and 18.8% of 96 NET patients (pts). An old clinical trial (Mortel C, 1984) suggested antitumor effects of estrogen/progesterone-directed therapies in NET. Yet the effects of an antiestrogen agent in NET pts whose tumor express ER and/or PR are unknown.

#2051 Do We Need Hormonal Therapy for Pancreatic Neuroendocrine Tumors? An Effort to Reduce the Size of PanNETs
Introduction: Pancreatic neuroendocrine tumors although rare , have been significantly increased over the past few decades. They range from indolent to highly aggressive in nature. Just like breast and endometrial carcinoma are hormonal dependant,

#2746 Immunohistochemical Biomarker Expression in Gastro-Entero-Pancreatic Neuroendocrine Tumors at ENETS Centre of Excellence, University Hospital Zurich, Switzerland
Introduction: Gastro-entero-pancreatic neuroendocrine tumors (GEP-NET) are a heterogeneous tumor entity with respect to biological behaviour and prognosis. This makes diagnosis and treatment a major challenge.

#789 Ovriectomy
Introduction: Bilateral OVX in female rats cause neurodegeneration in the nervous system of rodents and imitates systemic disorders in postmenopausal women. Synaptic modulation by estrogen is essential to understanding the molecular mechanisms of estrogen replacement therapy.

#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.

#2945 Misdiagnosis of Pancreatic Neuroendocrine Carcinoma - A Potential Threat
Introduction: Pancreatic neuroendocrine tumors (PNETs) are a rare clinical entity.Very less data is available in Pakistan on PNETs.Common metastatic sites are liver, lung and brain Reports involving metastasis to breast are almost negligible.
