Biochemical factors in the blood serum of neuroendocrine tumor patients with carcinoid syndrome
Introduction. Carcinoid syndrome is the most common functional syndrome in patients with neuroendocrine tumors. More than 40 biochemical factors are responsible for the manifestation of carcinoid syndrome, among which serotonin is the most important. The

Improving Segmentation and Detection of Lesions in CT Scans Using Intensity Distribution Supervision [PDF]
We propose a method to incorporate the intensity information of a target lesion on CT scans in training segmentation and detection networks. We first build an intensity-based lesion probability (ILP) function from an intensity histogram of the target lesion. It is used to compute the probability of being the lesion for each voxel based on its intensity.

Analysis of an EGFR mutation by PNA clamping method in lung carcinoid tumors [PDF]
Background Pulmonary carcinoid tumors consisting of typical carcinoid tumors (TC) and atypical carcinoid tumors (AC) are rare, accounting for 2–5% of all lung tumors. TC is considered a low-grade tumor with a rate of distant metastasis up to 12%.

Pioglitazone inhibits growth of carcinoid cells and promotes TRAIL-induced apoptosis by induction of p21(waf1/cip1) [PDF]
Background/Aims: We investigated the effect of the peroxisome proliferator-activated receptor-gamma (PPAR-gamma) agonist pioglitazone on growth and TRAIL-induced apoptosis in carcinoid cells.

Gastrointestinal carcinoid tumors [PDF]
carcinoid tumors (CTs) represent the commonest neuroendocrine tumors. Those in the gastrointestinal tract are diagnosed in surgical specimens, clinically, and using imaging techniques (endoscopy, echoendoscopy, CT, Octreoscan, etc.). The goal of this retrospective study was to review a personal series of gastrointestinal carcinoid tumors, and to ...

Somatostatin Analogues in the Treatment of Neuroendocrine Tumors: Past, Present and Future [PDF]
In recent decades, the incidence of neuroendocrine tumors (NETs) has steadily increased. Due to the slow-growing nature of these tumors and the lack of early symptoms, most cases are diagnosed at advanced stages, when curative treatment options are no ...

Fine needle aspiration cytology of hepatic metastases of neuroendocrine tumors: A 20‐year retrospective, single institutional study [PDF]
Background Fine needle aspiration (FNA) is considered an excellent technique for documenting metastatic neuroendocrine tumors (NETs). This study aims to evaluate the accuracy of FNA in diagnosing metastatic NETs to the liver and determining the grade ...
