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 ...

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 ...

The impact of re‐characterizing metastatic pancreatic neuroendocrine tumors: A prospective study
Journal of Neuroendocrinology, EarlyView.Abstract The biology of metastatic pancreatic neuroendocrine tumors (panNET) may alter over time. It remains to be defined if, how, and when this patient group should be recommended to re‐evaluate the characteristics of their disease. This prospective single‐center, longitudinal cohort study at Uppsala University Hospital, Sweden (NCT03130205 ...

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 ...

A Carcinoid Tumor in the Urinary Bladder With Uncommon Clinicopathological Presentation [PDF]
Iranian Journal of Pathology, 2017 Background: Carcinoid tumors usually originate from the enterochromaffin cells located in gastrointestinal tract and bronchopulmonary system. They may rarely arise in the urinary bladder, where this can be eventually miscued as any other commoner bladder

International Journal of Cancer, Volume 157, Issue 1, Page 116-125, 1 July 2025.What's new? This study used data from all 16 German cancer registries for colorectal neuroendocrine neoplasms to calculate incidence and relative survival. The data allowed differentiation by primary site, morphology (well‐differentiated neuroendocrine tumors—NETs, poorly differentiated neuroendocrine carcinomas—NECs and mixed neuroendocrine‐non ...
