#139 Association of carcinoid with noncarcinoid neoplasms
Introduction: Carcinoid tumors have a complex disease spectrum. Most have a benign clinical course, but some are aggressive, with invasive growth, metastasis and short survival. In carcinoid tumors, more than 20% are associated with noncarcinoid neoplasms. When the second tumor is a more malignant lesion, the prognosis usually is correlated more closely with the noncarcinoid malignant neoplasm.

#2129 Phosphohistone H3 (PHH3) Immunohistochemical Staining Outperforms Conventional H&E Mitotic Count in Classifying Pulmonary Carcinoids
Introduction: Pulmonary carcinoids (PC) are well-differentiated NETs and are classified as typical carcinoid (TC) and atypical carcinoid (AC). Despite the fact that TC and AC exhibit significant differences in patient survival, their classification depends on relatively subtle differences in mitotic count (MC). Although careful counting of mitotic figures (MF) is essential, it is a very subjective task, time-consuming and lacks of sensitivity and interobserver reproducibility, due to selection bias of the hot spots, heterogeneous distribution of MF, difficulty in distinguishing MF from similar chromatin changes (i.e. in apoptotic cells or due to crush, karyorrhectic debris, pyknosis or apoptosis).

#247 Carcinoid Metastases to the Breast: More Common than Previously Thought. A Presentation of 13 Cases
Introduction: Metastases from carcinoid tumors to the breast have been described as a rare phenomenon. Presentation and cytopathologic findings of these tumors can closely mimic that of a mammary carcinoma.

#2166 A Family Bronchial Carcinoid Tumor.
Introduction: Typical and atypical bronchial carcinoids are neuroendocrine tumors of the lung. Family lung carcinoid tumors are rare and have been described as very rarely in literature.

#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.

#70 The validity of Ki-67 as a prognostic indicator in patients with appendiceal carcinoid tumor
Introduction: Carcinoid tumors of the appendix are rare and often discovered incidentally through appendectomy. Most are clinically benign but may be associated with metastatic disease. Ki-67, a nuclear protein structurally associated with chromatin, is an excellent marker for measuring cell proliferation and it has been shown to correlate with the outcome in pancreatic and ileocecal carcinoids.

#104 Myocardial motion abnormalities in patients with carcinoid disease without overt carcinoid heart disease
Introduction: Cardiac abnormalities occur in 15-70% of patients with carcinoid disease, typified by fibrosis of the right-sided valves. Myocardial motion abnormalities in subjects without overt carcinoid heart disease have not been previously described. Tissue Doppler Imaging (TDI) allows quantative analysis of myocardial motion. We used this technique to investigate whether myocardial motion is reduced, suggesting fibrosis, in patients with carcinoid disease.

#105 A pilot study using biochemical markers to predict acrcinoid heart disease in patients with carcinoid disease
Introduction: Carcinoid heart disease (CHD) affects up to 15-70% of patients with carcinoid disease. Recent ENETS guidelines recommend regular echocardiographic assessment to screen for CHD. Chromogranin A (CgA) is a peptide widely used to monitor carcinoid disease progression. Neurokinin A is a tachykinin which may be a more sensitive measure of carcinoid disease progression and prognosis. N-terminal pro Brain Naturetic Peptide is used as a screening tool for heart failure and recent results suggest utility in the diagnosis of CHD.

#122 Molecular genetic findings in gastric carcinoid suggest possible neurofibromin/Ras pathway involvement in carcinoid pathogenesis
Introduction: The molecular pathogenesis of gastrointestinal carcinoid tumours is poorly understood. We have been undertaking molecular genetic investigations of a young woman with neurofibromatosis type 1 (NF1) in whom a gastric carcinoid tumor was detected following an episode of gastrointestinal bleeding. She was otherwise relatively mildly affected by NF1. In NF1, gastric carcinoids have been found previously only in patients with other predisposing factors, which were absent in this patient.

#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.
