Colon Cancer Clinical Trial
Tissue Procurement and Natural History Study of Neuroendocrine Neoplasms (NENs) Including Adrenocortical Carcinoma (ACC)
Summary
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 used.
Eligibility:
People aged 18 and older who have or are suspected to have NENs or ACC.
Design:
Participants will be screened with a medical history.
Participants will have a physical exam. Their symptoms and their ability to perform their normal activities will be reviewed. They will have blood and urine tests.
Participants will receive recommendations for managing their disease and potential treatment options. They will be able to ask as many questions as they would like.
Participants may provide saliva, blood, and stool samples for research. They will give tumor samples from a previous surgery or biopsy.
Participants may have optional biopsies. During biopsies, cancer tissue will be obtained using a needle and syringe. Tissue will be taken from the liver, lung, or a lymph node. Participants may have an imaging scan or ultrasound to help locate the tumor or area to be biopsied. They will receive local anesthesia and may be sedated.
Participants will complete a questionnaire about their family medical history.
Participants will have follow-up visits every 6 months. They will have physical exams and give samples. If their health changes, they may have extra visits. If they cannot visit NIH, they (or their doctor) will be contacted by phone or email.
Participants will take part in the study for all their life.
Full Description
Background:
Neuroendocrine neoplasms (NENs) are divided into neuroendocrine tumors (NETs) and neuroendocrine carcinomas (NECs). These are rare malignancies occurring for example in the gastrointestinal tract, islets of the pancreas, lung, adrenal medulla, thyroid C-cells, etc., and is a heterogeneous group of neoplasms with unique tumor biology, natural history, and clinical management issues.
The annual occurrence of NENs has been increasing in the United States (US) and worldwide. The current incidence in the US is about 6 per 100,000 persons a year and represents 0.46% of all malignancies.
Most NETs are sporadic, but they can be part of familial cancer syndromes such as multiple endocrine neoplasia type 1 (MEN1), neurofibromatosis type 1 (NF1), or Von Hippel-Lindau (VHL) syndrome. Poorly differentiated NECs are all high-grade carcinomas that resemble small cell carcinoma or large cell NEC of the lung.
Treatment for localized NETs is surgical resection, however, a variety of therapeutic options are available for patients with advanced NETs. When to apply a given option, what combination therapeutic approach should be used, how long treatment should be continued, and in what subgroup of patients a particular treatment option should be used is unclear and controversial.
Objective:
-To comprehensively and longitudinally evaluate the natural history of participants with NENs and allow sample acquisition for use in the study of NENs.
Eligibility:
Participants with confirmed or suspected NENs including ACC.
Age >= 18 years old
Design:
This protocol is a bio-specimen collection and natural history protocol in which samples will be collected from participants with NENs (from well-differentiated to poorly differentiated neuroendocrine neoplasm).
An accrual ceiling of 300 participants is planned over an accrual period of 10 years.
