unreferenced date October 2011 Tumor progression is the third and last phase in tumor development. This phase is characterised by increased growth speed and invasiveness of the tumor cells. As a result of the progression, phenotypical changes occur. Together with the progression, more and more aneuploidy occurs. This leads to expression in cell and nuclear polymorphism.

A Tumor Bank , as used in this article, is a term commonly used to describe a service that collects, stores and distributes fresh human tumor tissue for the purposes of biomedical research, primarily cancer research. A Tumor Bank is sometimes also referred to as a Tissue Bank , since normal tissues for research are also often collected. However, this function is distinct from a Tissue bank Tissue Bank which collects and harvests human cadaver tissue for medical research and education, and banks which store Biomedical tissue for organ transplantation. Cancer Samples Most tumor banks collect their tumor samples from discarded tissues not needed for pathologic diagnosis, after patients undergo surgery to remove the tumor. The tissue is often snap frozen in liquid nitrogen but may also be preserved in special fixative such as RNAlater which preserves RNA , or formalin which preserved tissue architecture. Many NCI designated Cancer Center Cancer Centers in the U.S. have a Tumor Bank to supply biomedical scientists with actual patient samples of cancer and associated adjacent normal tissue. This process is currently a high priority to support more Translational Research .

Tumor hypoxia is the situation where tumor cell biology cells have been deprived of oxygen . As a tumor grows, it rapidly outgrows its blood supply, leaving portions of the tumor with regions where the oxygen concentration is significantly lower than in healthy tissues. Hypoxic tumor cells are usually resistant to radiotherapy and chemotherapy , ref W. A. Denny, Prodrug strategies in cancer therapy, Eur. J. Med. Chem., 2001, 36, 577 595 ref but they can be made more susceptible to treatment by increasing the amount of oxygen in them. Bioreductive prodrugs also play a significant part in dealing with these kinds of cells they can kill the oxygen deficient tumor cells selectively as hypoxic cytotoxins . The study of tumors in such conditions was pioneered by Louis Harold Gray Dr L. H. Gray . Tumor hypoxia can also be a result of the high degree of cell proliferation undergone in tumor tissue which causes a higher cell density and thus taxes the local oxygen supply. There are several companies working to address tumor hypoxia Novacea, Inc., Proacta Inc. and Threshold Pharmaceuticals, Inc. These companies are developing the following drug candidates AQ4N Novacea , PR 104 Proacta and TH 302 Threshold Pharmaceuticals .

The term tumor metabolome describes the characteristic metabolic phenotype of tumor cells. Comparison of the metabolic characteristics of different tumor cell lines and tumors revealed that during tumorigenesis, the same alterations always occur in distinct metabolic parameters regardless of the basic metabolism of the tissues from which the tumor developed, such as brain or liver and regardless of the molecular mechanism by which tumorigenesis was induced. The characteristic attributes of the tumor metabolome are high glycolysis glycolytic enzyme activities the expression of the pyruvate kinase isoenzyme type M2, which is mainly in its dimeric form Tumor M2 PK increased channeling of glucose carbons into synthetic processes, such as nucleic acid , amino acid and phospholipid synthesis a high rate of pyrimidine and purine de novo synthesis a low ATP GTP CTP UTP ratio low AMP levels high glutaminolysis glutaminolytic capacities release of immunosuppressive substances dependency on methionine References cite journal last Mazurek first S. coauthors Grimm H.

Orphan date February 2009 Unreferenced date January 2007 Vestibular tumor s are growths that tend to develop underneath the serous tissue of the sublinguinal region. They may be found anywhere between the chin and the larynx or voicebox and are not more inclined to one side of the body than the other. They are predominantly present in adolescent females though they are not directly related to any hygienal issues. While surgery is the most often cure, deaths rarely occur due to the existence of vestibular tumors. History The first reported case of a vestibular tumor was in 1898 in Lancaster, Pennsylvania . Though there have been stories of growths of the like of vestibular tumors, this was the first medically reported case. At the time, surgery was too dangerous, so Emilia Walfen was forced to live with the tumor, which eventually grew to the size of a Concord grape . Issues arising from the presence of vestibular tumors While they are not always life threatening, they do propose a major health impediment. First of all, they can grow to be quite noticeable and after reaching a large size, are often easily irritable. Secondly they can lead to difficulty swallowing due to the pressure on the tongue or pharynx . Surgery is most often the decision made by the patients and it is rather affordable though if not treated may lead to life long problems. Category Types of neoplasia ... more details
