Changes on Chromosome 18 are Involved in Sporadic and Familial Ileal Carcinoid Tumor Development Abstract #262

Introduction: Small intestine neuroendocrine tumors (ileal carcinoid) is generally considered a sporadic disease. We have identified nine families with an ileal carcinoid tumor diagnosed in two or more individuals.
Aim(s): To compare genetic changes detected in familial cases to those in sporadic tumors to reveal genetic aberrations behind carcinoid development.
Materials and methods: Clinical and molecular studies of 55 sporadic and familial patients diagnosed with ileal carcinoids were performed. Molecular analyses of 61 tumors from 45 individuals, including eight familial and 37 sporadic patients, aimed at determination of global copy number aberrations using BAC and Illumina SNP arrays.

#500 Duodenal Carcinoid Tumors are Associated with Increased Survival and Earlier Detection When Compared with Jejunal or Ileal Carcinoids: A Population Based Study
Introduction: Seventy to eighty percent of small intestinal carcinoids (SIC) are found incidentally. Jejunal and ileal lesions can often be resected locally, but advanced duodenal carcinoids require high-risk pancreaticoduodenectomy.

#119 Valproic acid induces apoptosis-mediated cell death of the ileal carcinoid cell line GOT1
Introduction: Downregulation of tumor suppressor genes, evasion from apoptosis, and reduced differentiation are hallmarks of cancer that can be due to abnormal epigenetic control. Histone deacetylase (HDAC) is an enzyme involved in the deacetylation of histone proteins, resulting in chromatin remodelling and altered gene transcription. HDAC inhibitors are emerging as useful anticancer drugs.
