  2. Tumour heterogeneity - Wikipedia

    en.wikipedia.org/wiki/Tumour_heterogeneity

    A minimal level of intra-tumour heterogeneity is a simple consequence of the imperfection of DNA replication: whenever a cell (normal or cancerous) divides, a few mutations are acquired [2] —leading to a diverse population of cancer cells. [3] The heterogeneity of cancer cells introduces significant challenges in designing effective treatment ...

    en.wikipedia.org/wiki/Glioblastoma

    Glioblastoma, previously known as glioblastoma multiforme (GBM), is the most aggressive and most common type of cancer that originates in the brain, and has a very poor prognosis for survival. [6][7][8] Initial signs and symptoms of glioblastoma are nonspecific. [1] They may include headaches, personality changes, nausea, and symptoms similar ...

    en.wikipedia.org/wiki/De_novo_mutation

    A de novo mutation (DNM) is any mutation or alteration in the genome of an individual organism (human, animal, plant, microbe, etc.) that was not inherited from its parents. This type of mutation spontaneously occurs during the process of DNA replication during cell division. De novo mutations, by definition, are present in the affected ...

    en.wikipedia.org/wiki/Loss_of_heterozygosity

    A diploid population of 10 individuals, that bottlenecked down to three individuals repeatedly, resulted in all individuals homozygous. Loss of heterozygosity (LOH) is a type of genetic abnormality in diploid organisms in which one copy of an entire gene and its surrounding chromosomal region are lost. [1] Since diploid cells have two copies of ...

  7. Familial adenomatous polyposis - Wikipedia

    en.wikipedia.org/wiki/Familial_adenomatous_polyposis

    Familial adenomatous polyposis (FAP) is an autosomal dominant inherited condition in which numerous adenomatous polyps form mainly in the epithelium of the large intestine. While these polyps start out benign, malignant transformation into colon cancer occurs when they are left untreated. Three variants are known to exist, FAP and attenuated ...

  8. Response evaluation criteria in solid tumors - Wikipedia

    en.wikipedia.org/wiki/Response_Evaluation...

    Response evaluation criteria in solid tumors (RECIST) is a set of published rules that define when tumors in cancer patients improve ("respond"), stay the same ("stabilize"), or worsen ("progress") during treatment. The criteria were published in February 2000 by an international collaboration including the European Organisation for Research ...

    Hereditary nonpolyposis colorectal cancer (HNPCC) is a hereditary predisposition to colon cancer.. HNPCC includes (and was once synonymous with) [1] Lynch syndrome, an autosomal dominant genetic condition that is associated with a high risk of colon cancer, endometrial cancer (second most common), ovary, stomach, small intestine, hepatobiliary tract, upper urinary tract, brain, and skin.
