| gene expression regulation, neoplastic | Any of the processes by which nuclear, cytoplasmic, or intercellular factors influence the differential control of gene action in neoplastic tissue. (12 Dec 1998) |
|---|---|
| cell transformation, neoplastic | Cell changes manifested by escape from control mechanisms, increased growth potential, alterations in the cell surface, karyotypic abnormalities, morphological and biochemical deviations from the norm, and other attributes conferring the ability to invade, metastasize, and kill. (12 Dec 1998) |
| pregnancy complications, neoplastic | Neoplasms occurring during the course of pregnancy, or pregnancy during the course of a neoplastic disease. (12 Dec 1998) |
| neoplastic | <oncology, pathology> Pertaining to or like a neoplasm with new and abnormal growth, pertaining to neoplasia with the formation of a neoplasm. Origin: Gr. Plassein = to form (18 Nov 1997) |
| neoplastic arachnoiditis | Infiltration of subarachnoid space by neoplastic cells, typically medulloblastoma or metastatic carcinoma. Synonym: neoplastic arachnoiditis. (05 Mar 2000) |
| neoplastic endocrine-like syndromes | Endocrine syndromes due to hormone production by neoplasms of non-endocrine tissue, or by other than the usual endocrine tissues. They are often the first indication of a previously undetected neoplasm. (12 Dec 1998) |
| neoplastic meningitis | Infiltration of subarachnoid space by neoplastic cells, typically medulloblastoma or metastatic carcinoma. Synonym: neoplastic arachnoiditis. (05 Mar 2000) |
| neoplastic processes | The pathological mechanisms and forms taken by tissue during degeneration into a neoplasm and its subsequent activity. (12 Dec 1998) |
| neoplastic syndromes, hereditary | The condition of a pattern of malignancies within a family, but not every individual's necessarily having the same neoplasm. Characteristically the tumour tends to occur at an earlier than average age, individuals may have more than one primary tumour, the tumours may be multicentric, usually more than 25 percent of the individuals in direct lineal descent from the proband are affected, and the cancer predisposition in these families behaves as an autosomal dominant trait with about 60 percent penetrance. (12 Dec 1998) |
| communicating hydrocephalus | Type of hydrocephalus in which there is an abnormality in cerebrospinal fluid absorption; there is no obstruction to cerebrospinal fluid flow in the ventricular system or where the cerebrospinal fluid passes into the spinal canal. (05 Mar 2000) |
| congenital hydrocephalus | Hydrocephalus due to a developmental defect of the brain. Synonym: primary hydrocephalus. (05 Mar 2000) |
| postmeningitic hydrocephalus | Ventricular dilation following meningitis and secondary to obstruction of cerebrospinal fluid pathways. (05 Mar 2000) |
| posttraumatic hydrocephalus | Ventricular dilation following injury, due either to impaired circulation and/or absorption of cerebrospinal fluid or due to loss of brain substance (h. Ex vacuo). (05 Mar 2000) |
| primary hydrocephalus | Hydrocephalus due to a developmental defect of the brain. Synonym: primary hydrocephalus. (05 Mar 2000) |
| secondary hydrocephalus | An accumulation of fluid in the cranial cavity, due to meningitis or obstruction to the venous flow. (05 Mar 2000) |
