  colorectal cancer, colorectal adenocarcinoma, colonic adenocarcinoma, colorectal carcinoma; colonic carcinomas WKP
  Definition: Adenocarcinoma arising in the colon or rectum.
  Colorectal carcinoma is one of the most common cancers and one of the leading causes of cancerrelated death in the United States. Pathologic examination of biopsy, polypectomy and resection specimens is crucial to appropriate patient managemnt, prognosis assessment and family counseling. Molecular testing plays (...)

  JRC:10442 : cutaneous metastasis of a gastric adenocarcinoma.
  Etiology
  Gastric cancer is thought to result from a combination of environmental factors and the accumulation of specific genetic alterations due to increasing genetic instability, and consequently affects mainly older patients.

  Susceptibility
  Genetic association studies have identified 210 risk loci for inflammatory bowel disease, which have revealed fundamental aspects of the molecular biology of the disease, including the roles of autophagy and Th17 cell signaling and development.

• helminths
  24 November 2004

  Parasitic worms are highly differentiated multicellular organisms. Their life cycles are complex; most alternate between sexual reproduction in the definitive host and asexual multiplication in an intermediary host or vector.
  Thus, depending on parasite species, humans may harbor either adult worms (e.g., Ascarus lumbricoides) or immature stages (e.g., Toxocara canis) or asexual larval forms (e.g., Echinococcus species).
  Once adult worms take up residence in humans, they do not multiply (...)
