  • Bayerdörffer E et al (1995) Regression of primary gastric lymphoma of mucosa-associated lymphoid tissue type after cure of Helicobacter pylori infection. (springer.com)
  • germinal
  • B-cells undergo changes within the germinal centers to prepare them for making antibodies. (nccn.org)
  • Other DLBCLs start from B-cells that have been released from germinal centers. (nccn.org)
  • The postulated normal counterpart is post-germinal centre B cell with features of plasma cell differentiation. (atlasgeneticsoncology.org)
  • Most of the non-germinal center tumors fall into a specific category, termed the activated B cell (ABC) type, so named based on a resemblance in terms of gene expression to normal activated B cells, whereas others into an unclassifiable category. (uptodate.com)
  • tumor
  • Tumor cells have been shown to produce substances that stimulate the abnormal growth of new blood vessels that allow the tumor to grow. (knowcancer.com)
  • Since normal blood vessel cells divide very rapidly, it might be possible to stop tumor growth without harming normal tissues. (knowcancer.com)

  • 1 ⇓ ⇓ - 4 The tumor suppressive roles of FOXO proteins owe, in part, to their regulation of a large subset of genes involved in DNA repair, cell cycle regulation, and apoptosis. (bloodjournal.org)
  • DLBCLs
  • Some DLBCLs start from B-cells that are within the "factories" of your lymphatic organs. (nccn.org)
  • Diagnosis
  • In this article, we review prostatic lymphomas and discuss the differential diagnosis of high-grade malignant neoplasms of the prostate. (urotoday.com)
  • Shortly after my diffuse large b-cell lymphoma diagnosis, my wife suggested we go to MD Anderson. (mdanderson.org)
  • Reexamination and immunohistochemical staining of the previously biopsied lymph node specimen revealed the same clonal population of T cells positive for CD3, CD4, CD10, and programmed cell death protein 1 (PD-1) that was present in the skin and confirmed a diagnosis of AITL. (mdedge.com)
  • types
  • Immunohistochemical markers for normal follicular helper T cells-CD-10, chemokine CXCL-13, and programmed cell death protein 1 (PD-1)-can be used to differentiate AITL from other types of lymphoma. (mdedge.com)
  • involvement
  • We illustrate this with a case of a 46-year-old man seen with lower urinary tract obstruction who had diffuse involvement by a high-grade malignancy on prostate biopsy. (urotoday.com)
  • Workup with positron emission tomography-computed tomography demonstrated intensely hypermetabolic lymph nodes in the mediastinum, as well as widespread osseous involvement and involvement of the pancreatic tail, prostate, and urinary bladder, suggesting secondary prostatic involvement by a nodal lymphoma.
