Tissue Procurement and Natural History Study of Neuroendocrine Neoplasms (NENs) Including Adrenocortical Carcinoma (ACC)

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.

• INCLUSION CRITERIA:
• Age >= 18 years old
• The ability of the participant to understand and the willingness to sign a written consent document.
• Participants with the documentation of:

• histological or cytological confirmation of NENs or adrenocortical cancer
