  • Siewart described three different categories of OGJ adenocarcinoma, all based upon anatomic location: A Type I tumor, located between 5 and 1cm proximal to the OGJ, is an adenocarcinoma that typically arises from an area of intestinal metaplasia of the esophagus and can infiltrate the OGJ from above. (wikipedia.org)
  • Low-grade tumors may recur and infiltrate adjacent structures. (medscape.com)
  • Stage III lung cancer, though heterogeneous in its classification, includes non-metastatic but locally advanced disease with involvement of N1-N3 nodal stations and/or T3 and T4 primaries. (frontiersin.org)
  • By analysis of patient specific alterations in circulating tumor DNA in blood samples we aim to establish blood-based assays for early detection of lung cancer, treatment monitoring, and early detection of relapse in the primary and advanced setting. (lu.se)
  • Here, we performed immunohistochemistry on tissue microarrays (TMAs) containing 80 pairs of human pancreatic cancer specimens to assess the expression levels of Ring1B, H2AK119Ub1, EZH2, and H3K27Me3 in tumors. (oncotarget.com)
  • In either instance, it appears that presence of diffuse mucin in the peritoneal cavity (versus a localized collection of mucin) predicts a more aggressive tumor. (surgpath4u.com)
  • Aggressive tumor phenotypes can emerge through subtype changes and lineage plasticity as major mechanisms of treatment resistance in cancer. (sttrcancer.org)

  • There are various limitations in susceptibility, how host susceptibility ies may focus only on specific tumour epidemiological studies (e.g. statis- factors may modulate the impact of outcomes or may not be designed to tical power, exposure assessment, mechanistic events leading to tumour detect some types of tumours).

  • The International Endocervical Adenocarcinoma Criteria and Classification (IECC) reliably segregated EACs into human papillomavirus (HPV)-related and HPV-unrelated tumors according to the presence or absence of HPV infection-related morphology (apical mitotic figures and basal apoptotic bodies), which is easily identifiable under scanning magnification ( 12 ).
