About this study

Background: Neuroendocrine neoplasm (NENs)are rare cancers arising from the neuroendocrine cells and can affect almost any part of the body. They vary from low grade neuroendocrine tumors (NETs) to high grade neuroendocrine carcinomas (NECs). These tumors often occur in the gastrointestinal tract, pancreas, lungs, adrenal medulla (pheochromocytomas) or adrenal cortex (adrenocortical cancer) and other areas of the body mentioned below: * Gastroenteropancreatic neuroendocrine tumors (GEP-NET): stomach, duodenum, pancreas, colon, appendix, etc. * Liver and gallbladder * Adrenal tumors * Pituitary gland * Thyroid gland: medullary thyroid carcinoma * Parathyroid tumors * Pulmonary neuroendocrine tumors: typical and atypical carcinoid, small cell lung cancer (SCLC), large cell neuroendocrine carcinoma (LCNEC) * Extrapulmonary small cell cancer * Peripheral nervous system tumors: paraganglioma, neuroblastoma) * Breast and genitourinary tract Their rates are rising in the United States and worldwide. Researchers want to learn more about NENs through this natural history study. Objective: To study the natural history of people with NENs and obtain samples from them to learn more about the disease. The clinical management of all NETs is not standardized, with only a few FDA-approved therapies and we would like to learn which combination therapeutic approach should be used, how long treatment should be continued, and in what subgroup of NENs a particular treatment option should be …
