• lymphoid
  • For lymphoid neoplasms, e.g. lymphoma and leukemia, clonality is proven by the amplification of a single rearrangement of their immunoglobulin gene (for B cell lesions) or T cell receptor gene (for T cell lesions). (wikipedia.org)
  • lung
  • After investigations, the primary site became known in five cases (lung, colon and appendix, one case each, and the ovary in two cases). (uni-bonn.de)
  • In an American study of a database of over 60,000 lung cancers, GCCL comprised between 0.3% and 0.4% of primary pulmonary malignancies, with an age-adjusted incidence rate of about 3 new cases per million persons per year. (wikipedia.org)
  • For several decades, primary lung cancers were consistently dichotomously classified for treatment and research purposes into small-cell lung carcinomas (SCLCs) and non-small-cell lung carcinomas (NSCLCs), based on an oversimplified approach that is now clearly outmoded. (wikipedia.org)
  • tumor
  • A Krukenberg tumor refers to a malignancy in the ovary that metastasized from a primary site, classically the gastrointestinal tract, although it can arise in other tissues such as the breast. (wikipedia.org)
  • when the primary tumor is discovered, the same signet-ring cells are typically found. (wikipedia.org)
  • Most common primary anterior mediastinal tumor (20%) in adults but rarely seen in children. (wikipedia.org)
  • Neoplasm is an abnormal growth of tissue which, if it forms a mass, is commonly referred to as a tumor. (wikipedia.org)
  • Current English, however, both medical and non-medical, uses tumor as a synonym for a neoplasm (a solid or fluid-filled cystic lesion that may or may not be formed by an abnormal growth of neoplastic cells) that appears enlarged in size. (wikipedia.org)
  • tissue
  • Although there are many kinds of NETs, they are treated as a group of tissue because the cells of these neoplasms share common features, such as looking similar, having special secretory granules, and often producing biogenic amines and polypeptide hormones. (wikipedia.org)
  • invasive
  • This may reduce costs and minimize the discomfort patients have to undergo by curtailing extensive invasive investigations in search of unknown primary neoplasms. (uni-bonn.de)
  • groups
  • We compared the DNA repair gene expression in cultivated untreated primary fibroblasts of both patients groups using customized cDNA microarrays (800 genes). (aacrjournals.org)
  • list
  • We conclude that ultrastructural examination of adenocarcinomas in serious fluids can help to identify the primary site of certain neoplasms or at least shorten the list of possibilities. (uni-bonn.de)
