Improving Small Lesion Segmentation in CT Scans using Intensity Distribution Supervision: Application to Small Bowel Carcinoid Tumor [PDF]
Finding small lesions is very challenging due to lack of noticeable features, severe class imbalance, as well as the size itself. One approach to improve small lesion segmentation is to reduce the region of interest and inspect it at a higher sensitivity rather than performing it for the entire region.

The novel mTOR inhibitor RAD001 (Everolimus) induces antiproliferative effects in human pancreatic neuroendocrine tumor cells [PDF]
Background/Aim: Tumors exhibiting constitutively activated PI(3) K/Akt/mTOR signaling are hypersensitive to mTOR inhibitors such as RAD001 (everolimus) which is presently being investigated in clinical phase II trials in various tumor entities, including

Late-stage diagnosis of carcinoid heart disease due to lack of access to health care
Carcinoid syndrome (CS) is a unique constellation of symptoms caused by release of vasoactive substances from neuroendocrine tumors (Pandit et al., StatPearls, 2022).

Early Detection and Localization of Pancreatic Cancer by Label-Free Tumor Synthesis [PDF]
Early detection and localization of pancreatic cancer can increase the 5-year survival rate for patients from 8.5% to 20%. Artificial intelligence (AI) can potentially assist radiologists in detecting pancreatic tumors at an early stage. Training AI models require a vast number of annotated examples, but the availability of CT scans obtaining early ...

Gel chromatographic characterization of immunoreactive adrenocorticotropin in patients with ACTH hypersecretion [PDF]
We investigated the molecular size of circulating immunoreactive ACTH by gel chromatography in patients with ACTH hypersecretion due to various disorders of the hypothalamic-pituitary-adrenal axis.

Post-surgical Pancreatitis Masquerading as Recurrent Neuroendocrine Cancer [PDF]
Neuroendocrine tumours of the pancreas can have a spectrum of behaviour from relatively benign to aggressive. Resection can result in cure although metastatic disease is described.
