Neuroendocrine cells neurosecretory cells are cells that receive neuronal input neurotransmitters released by nerve cells and, as a consequence of this input, release message molecules hormones to the blood. In this way they bring about an integration between the nervous system and the endocrine system, a process known as neuroendocrine integration. An example of a neuroendocrine cell is the cell of the adrenal medulla innermost part of the adrenal gland which releases adrenalin to the blood. The adrenal medullary cells are controlled by the sympathetic division of the autonomic nervous system. These cells are modified postganglionic neurons. Autonomic nerve fibers lead directly to them from the central nervous system. The adrenal medullary hormones are kept in vesicles much in the same way neurotransmitters are kept in neuronal vesicles. Hormonal effects can last up to ten times longer than those of neurotransmitters. Sympathetic nerve fiber impulses stimulate the release of adrenal medullary hormones. In this way the sympathetic division of the autonomic nervous system and the medullary secretions function together. The major center of neuroendocrine integration in the body is found in the hypothalamus and the pituitary gland. Here hypothalamic neurosecretory cells release factors ... circulation.

Incidence In most series, LCLC s comprise between 5 and 10 of all lung cancers. Diagnosis LCLC is, in effect, a diagnosis of exclusion , in that the tumor cells lack light microscopic characteristics that would classify the neoplasm as a small cell carcinoma, squamous cell carcinoma, adenocarcinoma, or other more specific histologic type of lung cancer. LCLC is differentiated from small cell lung carcinoma SCLC primarily by the larger size of the anaplastic cells, a higher cytoplasmic to nuclear size ratio, and a lack of salt and pepper chromatin. Classification The newest revisions of the World Health Organization Histological Typing of Lung Cancer schema include several variants of LCLC, including a basaloid, b clear cell, c lymphoepithelioma like, d rhabdoid phenotype, and e large cell neuroendocrine carcinoma. In addition, a subvariant , called combined large cell neuroendocrine carcinoma , or c LCNEC, is recognized under the new system. To be designated a c LCNEC, the tumor must contain at least 10 LCNEC cells, in combination with at least 10 of other forms of NSCLC.

Endocrine oncology refers to a medical speciality dealing with hormone producing tumors, i.e. a combination of endocrinology and oncology . Few centres are specializing in hormone producing tumors only, due to the relatively low incidence . Most centres have gastroenterologists, oncologist or endocrinologists who deal with other diseases as well. One exception is the Uppsala Centre of Excellence in Neuroendocrine Tumors ref http www.endocrinetumors.org ref at Uppsala University Hospital in Sweden , where doctors treat only endocrine tumors.

Transarterial chemoembolization TACE , also called hepatic artery chemoembolization HACE , is a technique in which small embosphere s particles designed to block blood vessel s coated with chemotherapeutic drugs are injected directly into an artery supplying a tumor . This leads to two synergistic effects the injected emboli restrict the tumor s arterial blood supply, and the chemotherapeutic agent is delivered directly to the target tissue. As an added benefit, the chemotherapeutic side effects of this treatment are greatly diminished compared to systemic chemotherapy , as the chemotherapeutic agent is locally concentrated in the area of the tumor. TACE is used for several types of hepatic tumors, most notably hepatoblastoma s and neuroendocrine tumor s. Category Hepatology Category Oncology oncology stub ... more details
