The neuroendocrine carcinoma is defined as a high-grade malignant neuroendocrine neoplasm arising from enterochromaffin cells, usually disposed in the mucosa of gastric and respiratory tracts. The localization in the gallbladder is rare. Knowledge of these gallbladder tumors is limited and based on isolated case reports. We describe a case of an incidental finding of small cell neuroendocrine c...
Merkel cell carcinoma (MCC) is the eponym for primary cutaneous neuroendocrine carcinoma. Recently, a new polyoma virus has been identified that is clonally integrated in the genome of the majority of MCCs, with truncating mutations in the viral large T antigen gene. We examined the presence of Merkel cell polyomavirus (MCV) in a set of 17 frozen tumor samples by quantitative polymerase chain r...
Neuroendocrine tumors are very rare tumors that occur most commonly in the gastrointestinal tract. The occurrence of neuroendocrine tumors outside gastrointestinal tract is very rare but not unknown. Thus, neuroendocrine tumors and their primary seat can be found in the bronchi and lungs, as well as in the testicles, ovaries, prostate, etc. The occurrence of neuroendocrine tumors as a primary s...
Malignant tumors of the sinuses and nasal cavity are rare diseases. Squamous cell carcinoma is most common histological type (55–70 % cavity). The frequency neuroendocrine reaches 5 %. Currently, there no generally accepted standard for treatment sinonasal localization. If surgical associated with a significant deterioration quality life or poor outcomes, chemoradiotherapy can be recommended. T...
Florian Bösch Seite KKK 6 Abstract
Reg IV (RELP), a Regenerating protein family member, is constitutively expressed in neuroendocrine cells of the intestinal mucosa. The helix-loop-helix transcription factor Hath1 is the human homologue of murine Math1, which regulates the embryonic differentiation of neural and intestinal secretory lineage cells. Hath1 is constitutively expressed in a subset of mature secretory gastrointestinal...
Although potent androgen receptor pathway inhibitors (ARPI) improve overall survival of metastatic prostate cancer patients, treatment-induced neuroendocrine prostate cancer (t-NEPC) as a consequence of the selection pressures of ARPI is becoming a more common clinical issue. Improved understanding of the molecular biology of t-NEPC is essential for the development of new effective management a...
UNLABELLED Small cell lung cancer (SCLC) is an aggressive neuroendocrine subtype of lung cancer with high mortality. We used a systematic drug repositioning bioinformatics approach querying a large compendium of gene expression profiles to identify candidate U.S. Food and Drug Administration (FDA)-approved drugs to treat SCLC. We found that tricyclic antidepressants and related molecules potent...
BACKGROUND Small-cell neuroendocrine carcinoma has been recognized as a rare histologic variant occurring in only 0.5% to 2% of prostatic primary tumors. However, recent autopsy studies suggest development to this phenotype in up to 10% to 20% of the cases with hormone-refractory disease. CASE PRESENTATION A case of conventional adenocarcinoma before androgen-ablation therapy but showing prog...
