Fragility fractures in well‐differentiated gastroenteropancreatic neuroendocrine tumors: Results from a multicentered retrospective study

Journal of Neuroendocrinology, EarlyView.
Abstract Patients with gastroenteropancreatic–neuroendocrine tumors (GEP‐NETs) may present skeletal fragility that might be related to multiple factors, including bone metastases, vitamin D deficiency, hormone secretion, and disease treatments. This study examines the prevalence and determinants of fragility fractures in low grading (G1‐G2) GEP‐NETs ...

Minute ampullary carcinoid tumor with lymph node metastases: a case report and review of literature

World Journal of Surgical Oncology, 2009
Background Carcinoid tumors are usually considered to have a low degree of malignancy and show slow progression. One of the factors indicating the malignancy of these tumors is their size, and small ampullary carcinoid tumors have been sometimes treated ...

Automatic Brain Tumor Segmentation using Cascaded Anisotropic Convolutional Neural Networks [PDF]

, 2017
A cascade of fully convolutional neural networks is proposed to segment multi-modal Magnetic Resonance (MR) images with brain tumor into background and three hierarchical regions: whole tumor, tumor core and enhancing tumor core. The cascade is designed to decompose the multi-class segmentation problem into a sequence of three binary segmentation ...

Statistical mechanics model of angiogenic tumor growth [PDF]

Phys.Rev. E 85, 010901(R) (2012), 2011
We examine a lattice model of tumor growth where survival of tumor cells depends on the supplied nutrients. When such a supply is random, the extinction of tumors belongs to the directed percolation universality class. However, when the supply is correlated with distribution of tumor cells, which as we suggest might mimick the angiogenic growth, the ...

Constipation, the sole presentation of primary renal carcinoid tumor: A case report

Rare Tumors, 2019
Primary renal carcinoid tumors are quite rare. The pathogenesis of these tumors is unknown due to lack of enterochromaffin cells in the kidney. Because of nonspecific clinical manifestations and radiologic features, they are commonly misdiagnosed. Hence,

Bronchial carcinoid tumors [PDF]

Cancer, 1975
Twenty-eight pulmonary carcinoid tumors were reviewed histologically and clinically. Hematoxylin-and-eosin-stained sections were utilized, as well as special stains, including the argyrophil and argentaffin reactions. The 22 tumors located centrally, at the level of primary or segmental bronchi, had a microscopic appearance distinct from those located ...
