Neuroendocrine Tumor Markers

Frontiers in Neuroendocrinology, 2001
Tumor markers used in the diagnosis and follow-up of patients with neuroendocrine tumors are in most instances not specific for a given tumor and circulate under normal conditions in the serum, making their use as an early diagnostic tool difficult (low sensitivity).

Clinical and pathologic characteristics of appendiceal neuroendocrine neoplasms diagnosed during pregnancy

Frontiers in Endocrinology, 2023
IntroductionAlthough appendicitis occurs in approximately 1:1000 pregnancies, appendiceal neuroendocrine neoplasm (ANEN) diagnosis during pregnancy is very rare.

Neuroendocrine tumor theranostics

Cancer Science, 2022
AbstractTheranostics is a term coined by combining the words “therapeutics” and “diagnostics,” referring to single chemical entities developed to deliver therapy and diagnosis simultaneously. Neuroendocrine tumors are rare cancers that occur in various organs of the body, and they express neuroendocrine factors such as chromogranin A and somatostatin ...

Can a penalized-likelihood estimation algorithm be used to reduce the injected dose or the acquisition time in 68Ga-DOTATATE PET/CT studies?

EJNMMI Physics, 2021
Background Image quality and quantitative accuracy of positron emission tomography (PET) depend on several factors such as uptake time, scanner characteristics and image reconstruction methods. Ordered subset expectation maximization (OSEM) is considered

Renal neuroendocrine tumors

Indian Journal of Urology, 2009
Neuroendocrine tumors (NETs) are uncommon tumors that exhibit a wide range of neuroendocrine differentiation and biological behavior. Primary NETs of the kidney, including carcinoid tumor, small cell carcinoma (SCC), and large cell neuroendocrine carcinoma (LCNEC) are exceedingly rare.The clinicopathologic features of renal NETs diagnosed at a single ...

Gastroenteropancreatic Neuroendocrine Tumors [PDF]

CA: A Cancer Journal for Clinicians, 2018
Abstract Neuroendocrine tumors (NETs) are heterogeneous malignancies arising from the diffuse neuroendocrine system. They frequently originate in the gastroenteropancreatic (GEP) tract and the bronchopulmonary tree, and their incidence has steadily increased in the last 3 decades.
