Turcot syndrome

Lynch syndrome, caused by a germline pathogenic variant in a mismatch repair gene and associated with tumors exhibiting microsatellite instability (MSI), is characterized by an increased risk for colon cancer and cancers of the endometrium, ovary, stomach, small intestine, hepatobiliary tract, urinary tract, brain, and skin. In individuals with Lynch syndrome the following life time risks for cancer are seen: 52%-82% for colorectal cancer (mean age at diagnosis 44-61 years); 25%-60% for endometrial cancer in women (mean age at diagnosis 48-62 years); 6% to 13% for gastric cancer (mean age at diagnosis 56 years); and 4%-12% for ovarian cancer (mean age at diagnosis 42.5 years; approximately 30% are diagnosed before age 40 years). The risk for other Lynch syndrome-related cancers is lower, though substantially increased over general population rates. [from GTR]

MedGen UID:
78553
Concept ID:
C0265325
Disease or Syndrome
6.

Tumor Progression

A pathologic process in which alterations at the molecular level result in a more aggressive cytologic and phenotypic profile and clinical course of a neoplasm. [from NCI]

MedGen UID:
61255
Concept ID:
C0178874
Neoplastic Process
7.

Intracranial Neoplasm

A benign or malignant neoplasm that arises from or metastasizes to structures within the cranium. This includes meningeal and other tumors that occur in the spaces that surround the brain, and neoplasms of the brain. [from NCI]

MedGen UID:
287152
Concept ID:
C1527390
Neoplastic Process
8.

Epithelial Neoplasm

A benign or malignant neoplasm that arises from and is composed of epithelial cells. This category include adenomas, papillomas, and carcinomas. [from NCI]

MedGen UID:
277963
Concept ID:
C1368683
Neoplastic Process
9.

Cancer, Embryonal

MedGen UID:
199639
Concept ID:
C0751364

Ependymoastrocytoma

MedGen UID:
155907
Concept ID:
C0751677
Neoplastic Process
11.

Polar Spongioblastoma

A lesion characterized by the presence of neoplastic neuroepithelial cells with palisading nuclei. This lesion implies a morphologic growth pattern and it is not considered a clinicopathological entity. [from NCI]

MedGen UID:
154309
Concept ID:
C0555199
Neoplastic Process
12.

Base Pair Mismatch

The presence of an uncomplimentary base in double-stranded DNA caused by spontaneous deamination of cytosine or adenine, mismatching during homologous recombination, or errors in DNA replication. Multiple, sequential base pair mismatches lead to formation of heteroduplex DNA; (NUCLEIC ACID HETERODUPLEXES). [from MeSH]

MedGen UID:
109084
Concept ID:
C0600501
Cell or Molecular Dysfunction
13.

Astroblastoma

A rare glial neoplasm more commonly found in young adults. It is characterized by tumor cells with characteristics suggestive of an astrocytic origin (positive for GFAP), arranged perivascularly. The cells have broad, non-tapering processes radiating towards a central blood vessel. The biologic behavior of astroblastomas is variable, so no WHO grade has been established, yet. (Adapted from WHO.) [from NCI]

MedGen UID:
90811
Concept ID:
C0334587
Neoplastic Process
14.

Neoplasm of the central nervous system

A benign or malignant, primary or metastatic neoplasm that affects the brain, meninges, or spinal cord. Representative examples of primary neoplasms include astrocytoma, oligodendroglioma, ependymoma, and meningioma. Representative examples of metastatic neoplasms include carcinoma and leukemia. [from NCI]

MedGen UID:
88335
Concept ID:
C0085136
Neoplastic Process
15.

Neuroepithelial neoplasm

A neoplasm composed of neural epithelium, not necessarily a neoplasm located in the neural epithelium or neuroepithelium. [from HPO]

MedGen UID:
60215
Concept ID:
C0206715
Neoplastic Process
16.

Neuroectodermal neoplasm

A neoplasm arising in the neuroectoderm, the portion of the ectoderm of the early embryo that gives rise to the central and peripheral nervous systems, including some glial cells. [from HPO]

MedGen UID:
60072
Concept ID:
C0206093
Neoplastic Process
17.

Neoplasm of the nervous system

A benign or malignant, primary or metastatic neoplasm involving the central or peripheral nervous system. [from NCI]

MedGen UID:
45046
Concept ID:
C0027766
Neoplastic Process
18.

Embryonal neoplasm

A usually malignant neoplasm composed of primitive (immature) tissues that resemble fetal tissues. Medulloblastoma, Ependymoblastoma, Pineoblastoma, and Wilms tumor are representative embryonal neoplasms. --2003 [from NCI]

MedGen UID:
45034
Concept ID:
C0027654

39314
Concept ID:
C0085584
Disease or Syndrome
20.
